oh sh*t moments

[abvw]

Spent all day trying to do a timing belt on a Ford Focus with the 2.0L Zetec motor. Scrambled around the shop trying to find a 5mm thick piece of steel to lock the twin cams in place, got frustrated and somehow rigged 3 wrenches on the cam to hold it in place. Finished it, crank over the engine.. It ran smoothly for about 5 seconds, then it started to miss and the engine light came on..

Removed the belt, this time I found two 5mm hex L keys, jammed them in the slots and installed the belt. Turned the crankshaft over twice, double checked the timing. Everything looked okay..

My coworker started the car, as I stuck my head out of the wheel well and peek over the fender, the timing belt was flung across the engine bay right in front of my eyes. The motor stalled abruptly and both our jaws were on the floor. I have forgotten to install the crank pulley belt guide and the timing belt slipped out and was whipped across the shop.

My face turned white and felt a chill down my spine when my coworker told me the Zetec were interference. I was about to break down and cry. I don't quite remember what happened after that, all I was thinking was "oh **** oh **** oh ****" and proceeded to "finish" the job.

Thank goodness the motor ran fine after the third timing belt install..

High-school job at grocery store, boss yells to get some pallets moved out of isle in store. Run to back room to get the electric fork lift that's plugged into charger overnight. Grab the handle and pull down so it kicks forward dragging the charger off the wall shelf and crashing to the ground. Dammit, how did that happen?? Apparently no safety setting on forklift so it worked all the time when it had juice, even when plugged into charger.

Luckily the owner was pretty understanding and I didn't get ripped too bad. Never did know how much to repair / replace that forklift charger but it couldn't have been cheap. Ended up staying at that job some years during college and given responsibility of about 1/3 of store stocking and ordering, so all was good.

In 98 I had a Honda that I wanted to make faster. I installed an aftermarket exhaust. After a week of hearing a rattle under the car I decided to fix the problem. The car was lowered so that I could not get dads jack under it unles I parked at the end of the driveway where it met the street. I jacked the car up, looked under, found the heat shield making the noise and went to grab the rivet gun. Went back under the car and put the rivet in but it took about 30 minutes to complete the work. I went to get out from under the car and noticed I had zero room to wiggle. It took everything I had to drag the ground on my back to get out. Talking to dad he said "told you a while back the jack sinks and to use jack stands". I have never crawled under a car again without stands. It was really close that day.

I needed to replace the carrier bearing on my f250. Well my driveway at the time had a good slope to it. Not thinking I take the last bolt and I notice the truck start moving. I was VERY lucky to barrel roll out, my hand got run over but it wasn't a big deal. What was a big deal was my 7k pound truck heading straight towards my neighbors house. Luckily it hit the curb and proceeded to steer left where it drove off a 5 foot high retaining wall and got hung up on the axle. Big oops

I was replacing the radiator on the owners wife 08 explorer, which is cased together with brackets to the condenser.it was my first one so I was following the book witch tells you to separate them in vehicle and drop the radiator down.i don't remember how but all of a sudden I hear a small sshshhhh I move it around then a big swoosh of free on and pag oil.....I just put a big gaping hole in the condenser on the owners wife's ride on a Saturday. She was steaming that she had no ride for the weekend.but we got it all fixed and the sold it not long after.now when i do those i recove the ac real quick and pull both out together and seperate them on the floor.another time I was working on a 98ish expedition of a good customer, I pulled foward in the bay so the door could clear the rack, I thought I put it in park and left the door open and left it running. I didn't realize the shift indicator was off and was actually in reverse, it went strait back and bent the door back.luckily we have a body shop and I asked the main guy if he could save me, he said yea but wat ever you do don't try to close the door back.that was the first thing I did.hes a great body guy and hea was able to fix it pretty quick.learned from it and now if I open a door with engine running and in park I apply the parking break.

A couple of years ago we enclosed an outdoor area where our gas meter was. The meter counter reported it and so we had to move it outside. So once they came and put the new meter where it had to go, the utility co asked us to cut the concrete to expose the existing gas pipe so the could do the transfer. I understood dig up the pipe at all costs using every tool at my disposal...
So after putting the forklift attachment on the skid steer to help break up the soil under the concrete, we kept digging. I was expecting an iron pipe, to my unpleasant surprise I hit the plastic PEX-like pipe and whoosh! After we evacuated the building and businesses around us, after all the emergency vehicles left and the utilities guys started hunting for the master shutoff and cutting more concrete in the parking lot...
Long story short it was around a $15,000 bill.
I don't dig anymore.
Cheers

True story titled "One last Ride"

I had a 97 eclipse 5 speed with the 420a engine. Decided I wanted to trade the car. Craigslist. Found a guy who wanted to trade his 91 z28 with a mildly built 350 even for my car. Reason he wanted to trade was he had a 97 eclipse himself, but totaled it, and couldn't afford to drive the z28 everyday.

So, we set up to trade on Monday. My great idea was to give it one last top end run and Track top speed with a cell phone app.

1st gear - 30mph
2nd gear - 50mph
3rd- 80/90mph
4th.. err.. 2nd... BOOM!

Hand slipped shifting from 3rd to 4th, and went into 2nd, at about 85mph. Redlines at 6500rpm,seen the tach jump to 9000! By that split second it was all over. Car shut off, costedfor a mile. Trailered it home. Spent 8 hours running to them parts store and doing a timing belt. Jobs done, nothing. Found out it was an interference engine 8 hours and $125 later. Spent 20 minutes taking off the valve cover. Destroyed springs, lifters, retainers etc.

Was going to replace the engine. Till I found out a junk yard engine was $800. Sold it to a guy to become a mud truck.

Last week I did a tuneup and valvecover gaskets on an 04 Intrepid, with the 3.0 mitsubishi engine. To remove the valvecovers, you have to unbolt and remove the front timing cover, and unbolt the rear one from the rear valvecover. Timing covers are old and brittle plastic.

I did the job, put everything back together. Fired the car up, made a BANG! noise under the hood and died. Found rear timing cover blown to smithereens. Car ran, but crappy. Found bank 1 cam off by three teeth. Installed new timing belt, all was good. Found a metal grommet all bent to **** on the floor under the timing belt area of the engine, same type that goes in the timing covers where the bolts go, keeps you from overtightening them and cracking the mounting ears. I surmised that one of the rear timing cover mounting ears "lost" its little metal grommet thingy while I was doing the valvecover gaskets, and somehow got stuck in the timing belt.

That little mishap only cost the customer an additional $200 on top of the other work. They got a much needed timing belt the hard way (old one was cracked and about to break anyways).

Goes to show you that no matter how good you get at something, you still Eff up from time to time!

 

[Danglerb]

My first car Alfa 1600 spider, first time I ever worked on a car, I'm changing the plugs and decide to "check the timing" and very carefully turn the crank with a wrench and use a screwdriver to check for TDC. I get cam timing spot on, then crank the engine with the starter before checking a second time, but forget to take out the screwdriver. The new exhaust valves took a serious bit out of my behind.

My first oil change, drain out the oil then get the bright idea oil is maybe "stuck" in the motor and start it up to get the last bit out. Lots of noise as the lifters collapsed, but shut it off quick and no apparent damage.

 

[Hafen_Kafer]

Back in the day, (when I didn't know about this forum) I could, (tried) fix anything with an adjustable wrench, a Philips and a flat heat screw driver.

One time while changing the shoes of the bug. I was trying to remove the springs with the flat head screwdriver. It kept slipping and slipping. The last time it slipped and I almost stab a friend in the face. The thing stopped like two inches from his face.
I've never been scared like that before.
And thankful to God as well.

 

[laser3kw]

I was working for a trucking company as a go - fer.
I jumped in the company pick up to back it up into the bay to unload parts.
I thought "I just need to back up a little." So I left the drivers door wide open, popped it into reverse, backed up far enough to catch the drivers door on the concrete guard post and bend it around.
That was also my last day.....

 

[t4runner]

I was a youngster at a garage when an elderly man came in with his 1965 Pontiac. He said it was making a noise when he would pass someone on the road. My boss asks me to give it a test drive so off I go, when I round the corner I put the pedal to the metal and bang just like that it stops running. I open the hood and theres a hole the size off a soft ball in the side of the block with a rod sticking out. Being young and stupid I go back to the shop on foot and tell the old guy [ with my boss standing there ] I got good news and bad news, the good news is I found the noise and the bad news is and I show him the broken rod I have in my hand. I thought the old guy was going to have a heart attack. My boss was not to happy with me to say the least. I ended up working there for over 10 years

 

[firebox40dash5]

1st gear - 30mph
2nd gear - 50mph
3rd- 80/90mph
4th.. err.. 2nd... BOOM!

Oof. I know that feeling. Did it a couple times with my WRX at the strip, had a nice smooth short shifter, and not only were the gears nice and smooth, there was almost no gate between them. I don't have a clue how I did it, since I usually sidestepped the clutch, but I think I managed to mash the pedal back in before it fully engaged. I'm almost as surprised it didn't break the tach needle off or spin it when it wrapped around the bottom.

 

[86k10]

During my first year I was putting back a Ford straight 6 300 and grabbed too long of a water pump mounting bolt and punctured a hole into the 1st cylinder. Boss was pissed but the next day he was calmer and said that he is surprised he hasn't seen it before.

I had a 1996 Z28 camaro with the 6 speed manual. I was going down a hill doing about 45 MPH one night. I had just shifted down a gear when I noticed some weird light behind me. I couldn't figure it out, then it dawned on me that it was the reverse lights. Luckily I had not let the clutch out. It never made any funny noise going in to reverse, I am so glad it was dark, otherwise it would have been really bad.

I had to remove a broken screw out of a special infared light for aircraft. It was in final assembly and ready to ship when the assembler broke the screw. The last thing I was told was "do not damage this". I had the light laying on my bench on a shop rag, I had my verniers in my back pocket, I turned, the points on my verniers caught the shop rag and the light went to the floor. A $25,000 light now broke

At another shop I worked at, I was the setup man and groupleader. We had a new job to be set up using a special cutter. The cutter was special made in Switzerland and they said it was $15,000. The last thing I was told was to not damage the cutter. I always would run enough parts so the guys running the machine could make rate and then some. I loaded the parts, ran a set (3 parts = a set), and while they were running, I was cleaning the cosmoline off of the other parts. With the cycle times, you couldn't quite clean three parts while the machine was cutting parts, so I turned and pushed the button to stop the machine. The Machine was an OKK and we were using the head in the bore mode to come down, cut the parts and then retract. This was the only machine in the shop that when the cutter was off, the head would still come down. So I shut off the cutter, started cleaning parts and heard a very loud crunch. The cutter was totally trashed, the fixture was trashed, all I could thing was "oh ****". I went up to the supervisor and told him I had something to tell him, and he knew.

If someone has me do something and they say"whatever you do........." I will not touch that part for the rest of the day. Because every time I'm told that, something goes wrong.

 

[bugnout]

When I was 18 I went through about half dozen jobs in the same number of months. Just couldn't find anything that I was a fit for.

Worked as a bagger in a grocery store, quit that job because a friend talked me into delivering cars for a dealership. Dealership paid just enough to cover expenses (not including motel) so I wasn't making any money at all, and it was days on the road without a shower, so I quite that. My mom talked me into signing up for Community College. didn't really see any point in that, but I did it anyway.

I took a job as the all night attendant at a gas station, 10pm to 6am. Thought I could do my homework before my first class at 8:00AM at the local community college. I sat in this both in the middle of the gas pumps and took the money through one of those sliding drawers. The station had drive through car wash, the kind that you have to put it in nuetral and let it pull you through.

I had trouble staying awake for the whole shift and got in the habit of turning off all the pumps and shutting the carwash rollup door on the far end of the building, the door I couldn't see from the booth. That way I could take a little nap without fear of a drive off. Figured anyone wanting gas or a wash would knock on the window.

I'd been working there maybe 2 weeks. Saturday night at about 2:00am a guy in a brand new firebird woke me to turn on the pumps so he could fill up. As he's paying he asks to use the car wash, I take his money and power it up. He gets lined up and going, and I go back to napping only to be woken 5 minutes later by the same guy pounding on the window. He's wet and not happy.

Turns out I had forgotten to open the rollup door on the exit of the wash and he had to jump the track to avoid crashing into the door. the tire roller ended up jamming the bottom of the door, and it took me about 15 minutes to get it open so he could get his car out. He was pissed!

No damage to his car except maybe needing an alignment. The bottom section of the rollup was bent up pretty badly. Boss came in at 6:00am. I quit before he could fire me.

I found a job at an aluminum extrusion factory working on the paint line. I held that job for all of 2 shifts. Just long enough to pay for the steel toe boots I had to buy. I just didn't have the assembly line mentality. After that I worked as a stockman in an appliance store. Two weeks into that job, I joined the Air Force, but stayed on until I left for boot camp.

 

[porschedude996TT]

I was working on the flightline at a high performance twin engine aircraft plant and wondered if I could start both engines at the same time... Supervisor comes out of the hanger just when I hit both starter buttons. Busted and no it didn't happen, engines turned too slow to fire. No damge but did I look like an idiot to the boss.

 

[ijroorda]

At a construction job I worked for a couple of summers, I backed into a brand new trailer with another almost new trailer - right in front of my boss. It was completely my fault because I wasn't even looking in the mirror, but instead of getting mad at me, he tore everyone else in the yard a new one for not spotting me while I backed up. Fortunately it was only light cosmetic damage to both trailers.

now if I open a door with engine running and in park I apply the parking break.

In California you can probably get away with that. Here in the rust belt, if you apply a parking brake that doesn't get used regularly, it's never coming off!

 

[aka Larry]

I worked on putting a clutch in a V6 Probe GT for a friend. It was a PITA to say the least. We were working on it at another guys shop since he had a lift and the PGT owner lived out of state. It was late when we were done and to top it off the clutch just would not disengage. We called it a night and had another friend haul it back to my garage on his trailer.

Later that night I woke up about 4:00am with a oh, **** thought of "I bet I put the damn friction disc in backwards". It seemed totally logical so I called my friend and told I I f*cked up, but I will fix it. Took then transmission back out and F*CK! The friction disc was installed correctly! The "clutch kit" he gave us to use had parts from three different manufacturers (disc, pressure plate, lightweight flywheel) and when compared to an OE unit the OA height of the pressure plate fingers looked quite different. I was about 95% sure this was the issue, but I called my friend to let him know I didn't screw up, the one who sold him these parts likely did. Since this was the only plausible scenario luckily we called and found an OE clutch kit at the local parts store. I told my friend we would install this OE clutch kit and either it worked or it didn't but either way I was tired of f*cking with this car and he could come get it or I could set it on fire. Either way I was done with it. We installed the new clucth and it worked perfectly.

Lesson learned...compare old and new parts before reassembly to be sure they are correct!

 

[marklandon]

pulled a ground chain (steel rope used as an indicator that a high voltage electrical line is de-energized) over a hot 34500v line.
when the CB reclosed in the station, it blew the ground chain into about a thousand pieces............ i still hear that noise

Now how could that happen Not like I have not herd the same sound before and yes its loud

 

[ianguilly]

Backed the company van into a parked car. Boss laughed about it.

 

[Rewind97]

Wrecking the company truck after only being there a couple of months.

 

[Blackmarket]

Was operating the front-end loader to move a pile around.

Over a year ago, the company mechanic installed a quick detach kit to it. This allowed us to change between bucket and snow blade. Problem is, he didn't modify the tilt stop.

So I haven't use this piece of equipment much because I don't work at this site that often. Picked up a pile then went to dump it. Dumped, then tried to tilt bucket back. Nothing but a loud bang! Bucket had overcentered itself because the stop hadn't been changed. Due to the difference in the geometry of new quick detach kit, it allowed it to go overcenter and destroyed the dogbone that controlled the bucket tilt.

Wasn't necessarily my fault. I just happened to be the poor ******* that finished it off.

A used pair was over $2000.

Like I said not really my fault but I still felt horrible.

 

[SSGTWC]

Getting fired for being right.... The guy next to me was working on an international truck and thought the timing was off, rebuilt the card, pulled the timing chain, still could not get it to run. I had been telling him and the owner that you time an international v8 on number 8 all week. The owner called the international dealer and walked out and said, huh, you time those on number 8. I lost my **** and told him I had been telling him that all week, we got into a fight and he fired me, only job I ever been fired from and my Dad fired me.....(yes, my dad was the owner) LOL.....

and International engines don't have timing chains

 

[24ModelTFord]

My uncle bought a new dodge van in the early 80's. Had it decked out with captains chairs, table, big side windows, etc. Drew the line at what they wanted for a sunroof. He decided it would be cheaper to install one himself. Went and bought the biggest one he could find, layed it out in the shop, climbed up and cut the hole. Too bad when he measured for the hole, he used the outside of the rubber dimensions. I'll never forget it - he set the sunroof over the hole and it fell right into the van.....priceless......

Once, when asked to get rid of an email account on a Mac... I did.

I'd said repeatedly that I was uncomfortable working on the thing as I'm primarily a Windows guy, but they asked nicely so I said I would do it.

Trouble is in the difference between the way the Mac email program and the way Microsoft's Outlook handles accounts. Apple treats the email account and all the mail you have ever downloaded as one item... So if you delete the email account because you no longer use it... It deletes all the mail you have ever retrieved from that account. No warning and no backup. In the 13 years I've been a systems admin I have never screwed up that badly, before or since. I'm the guy that does the extra backup just in case.

I felt so horrible... No possible recovery according to Apple. Her backup hadn't been working for years, and was a future project.

I apologised, and she accepted. Telling me she understood.

She lied. She fired my company three days later.

I don't really blame her. But I wish she hadn't said she understood.

 

[Heavy Metal Doctor]

A few others of my own doing --
Tipped a forklift on its side and crashed it through a cinder block wall when the brakes quit on a hill.

Hit couple different cars with our big trucks - local towing guys like to leave cars parked willy-nilly - even up on curbs - all around our shop. One was a lunch wagon truck up on the deck of a roll back parked with the tail end sticking out across the alley to my shop - backed out in pouring rain (couldn't see **** in the wet mirrors) and nearly shoved it off the side of the roll back. Another time they parked one of our trucks in on the street (cars double parked), so I swung the front end up onto the side walk to wiggle out of the space backward - didn't realize they also had a Buick sedan parked on the sidewalk and caved in the trunk before I felt anything.

Took the boss' new 1 ton pickup (against my will - I wanted nothing to do with it, because I know how uptight they get about new stuff getting messed up) to deal with unloading trailers from a tractor trailer. Being in a hurry, I got in the freight truckers blind spot and he moved. The side rail of his trailer trashed a front fender before I could get outta the way. The funny part was I knew it was purely my fault, but the boss' son (was there / saw it) wanted the truckers insurance info like it was that guys fault The truck driver said "how about if I bill for scratching the side rail of my trailer?"

Back in the mid eighties I was working for Anvil mines in the Yukon (was one of the biggest lead/zinc mines in the world at the time) as a haul truck driver. Night shift, guy up in the tower tells me to dump in a particular spot, totally dark. Was driving one of those Euclid ore trucks, raise the back and FLASH! Top of dump box hit one of the main power lines to the mine. Wasn't killed due to the 12 ft tall rubber tires which insulated me. Took out power to the mine and townsite for 6 hours. Can't begin to imagine what 6 hours of lost production cost the mine but it was probably in 7 figures. Wasn't fired only because the guy in the tower told me to dump there. They fined me a days wages though.

 

[turdferguson13]

When I was working as a lot tech at a dealership I was told to pull out a TDI Toureg so the people buying it could drive it home. They had liked it so much they decided to buy it without even a test drive. Salesman was in kind of a hurry and that made me hurry a little too. Thought I had enough room between another car on my side and a hand rail on the passenger side. I was wrong. Scraped the passenger side door pretty good. The people buying it looked at it and said some stuff about painting white being difficult to blend or whatever and left not too long after.

A week or 2 later the car came back from paint and I cleaned it really nicely and they came back to check it out. They bought it anyway! 2 and a half years later I still work there.

 

[metal1313]

Coming home from work one night I fell asleep behind the wheel on the highway. I awoke upside down to a random trucker frantically trying to undo my seat belt. He cut the belt and dragged me out before I figured out what was going on.
I fell asleep and gunned the fully loaded f550 to top speed before drifting into the wall then down an embankment. Rolled it a few times. I had told my boss I wasn't comfortable driving home but he wanted us out of our motel that night. He wasn't too mad at me, but then had to tell my parents I was in the hospital. They have been friends for 30 years, so he was a little worried about their reaction

Now that was funny right there. I would have loved to been there to see that in person.

I had work release my last two years of high school. I worked for a high end European car shop in Houston. One day the owner of the company told me to flush and fill the oil in the lower end of the transom on his boat so he could entertain friends that coming weekend.

I drained the oil, pulled the fill plug and filled it back up. The following Monday I, and my dad (who was the shop manager, and knew nothing about this) got reamed for almost killing everyone on the boat. It would seem that when you drain the lower transom on an inboard/outboard, you also drain the upper. I did not know this.

The company owner and his friends all found out at full throttle.

The company owner made my dad pay for it, out of his pocket, $1800. Still don't quite understand the logic there.

When I first started rough carpentry/construction my boss told me to keep my hammer loop toward my backside. I didn't listen. Shortly after being told that, I walked down a ladder with my hammer in front of my tool belt. It caught one of the rungs and I went for a fun ride.

The ladder separated from the roof's edge with me stuck to it. Unfortunately 10-15' behind the ladder was a roll off dumpster that the ladder used as a pivot point a few feet below me causing me to speed up my impact into the ground.

I hit the ground so hard with my back it knocked the wind out of me - only to be smashed in the head with the ladder. The three guys on the roof were howling with laughter. All I could see was their faces on my way down.

Lesson learned, the hammer goes in the back for a reason.

I worked the rest of the day/week/summer/life never hearing the end of that one.

You my good man are correct, I did not take it apart, and I told the guy that, but hey, might as well be right twice right ?

 

[Thumper68]

A good friend was using my shop to paint a new bumper for his truck, after he had cleaned up and left I had a small welding job to do, I got it all tacked up and started to do the finish welding, a few seconds in I hear this "whoooommmpphh" sound I flipped up my mask and looked around, there was burning rags and paper towels all around and the can liner from the "flash proof" can was inside out. Evadentlly he had forgotten to close the lid and the thinner soaked rags had exploded!

Took me a few minutes to collect all the rags and toss them out the door.

Another time I had just taken the bench seat out of my truck and set it aside for a guy to come and get, I was welding away when I smelled a rancid smoke, turning around the seat was on fire. There had been a split in the vinyl and a spark had started the foam on fire, that one called for use of the extinguisher.

Umm...oops....

My own personal oh shat moment most recently happened today actually, did an R&R on a dodge 4x4 trans, and when re-installing the transfer case I had it on the tras jack, I turned around to grab my 14mm wrench off my tool cart and BAM the t case fell off the jack, and busted the tail shaft housing....F%€¥£%#!!!! Wound up stealing one off another 244D transfer case in the build room.

 

[Chuck122]

once while go-karting i checked the sparkplug to adjust the carb but forgot to tighten it before going on the track. at some point the damn thing popped out. the sound of an engine that is 8'' from your ear doing 10 000 rpms without a plug scarde the **** out of me. and at some point the plug grounded on my arm... ouch
it's hard to react cause you really don't know what is happening, you are focused on your line, gear changes, trottle input, braking and then BAM, loud noise pain on your arm
i went wtf for a few seconds
lesson learned!
