chrysler - hemis got plugs every 30k - the 3.7 every 15 k
I thought OBD2 mandated 100k plugs , but like every other law , it only applied ro GM

Well what can you do? I look at plugs at every service interval. I gotta tell ya', the Chrysler motors love to eat 'em. If you're lucky, you can clean and re-gap them--usually I'm not lucky.

Modern cars with aluminum heads and current spark plugs do not need anti-sieze or oil on the threads. Install the plug and torque to spec is fine.

If you really want to use anti-sieze on older cars with aluminum heads it's ok for older cas without OBD2 or cats.

Personal choice but I don't use anti-seize.

Interesting points. Could you please elaborate as to why it's okay to use anti-seize/oil on older cars (particularly why OBD2 or a cat would preclude its use) and why not on newer cars?

Moose,

Good job, where is squirrel?

Did you put iridium plugs in that M102? All the Mercedes distributor engines with EZL should use copper plugs. Here in the states many cars that won't pass smog checks and have rough idles are attributed to "fancy" plugs. Also these should use non resistor plugs.

The older Mercedes engines sensitive to the wrong plugs, I had a guy with a 280SL that would not start, told him it was the plugs. Spent two days checking everything fuel and electric only to find he had just replaced the plugs with Iridium plugs.

Interesting stuff there, Steve. I believe these to be Iridium, the boxes are in foreign. I haven't started it up yet, spent the last 13 hours working on it, still going. It did take a while to start, maybe twice as long as usual, and sometimes idles and runs a little rough. Thank you for the info, will hunt down some copper plugs today!

Here, have an e-beer on me for the help! :beer:

Very informative Moose...Thanks for the "how-to" on changing spark plugs. I will be referring to your process at my next change-out. I hope to see more of your insightful automotive photos soon.

BTW: I think "raccoon" from Montreal likes you... :thumbup:

I liked that a lot. By installment twenty, that little moose is going to be pretty grimy from sitting in dirty engine bays and whatnot.

What do you use to gap the plugs? The plugs I bought for my Formula (stock replacement plugs) were not properly gapped, so I bought a cheap little gapping tool for the job. I'd like to find a more high quality version, though.

Nice write up Moose, thanks.

The only suggestion I would make for the Novice audience is that you take a few moments before taking plug caps off to put as bit of tape with the cylinder number on so that you get the correct lead on the right plug when you put it back together.

Moose, can you ship your little fuzzy self down here and change the three rear plugs in my wife's minivan? They are really hard for a normal-sized guy like myself to get to. If only I had a couple more elbows in each arm. I will gladly give you a large bag of Moose Chow for your time and cover the shipping costs both ways.
Also, the next time you see your veterinarian, ask him about those fuzzy spots on your antlers.

those picts were pretty hilarious. I feel weird admitting I thought they were 'cute.'

Does the moose have bendable wires inside to hold a fixed position?

Minivans are easy to change the plugs. Gms I rock the motor fwd with a special tool or fords etc I crawl underneath. Break them loose with a midget rachet and then buzz them out with the air rachet. Then buzz them in with air rachet and tighten with midget rachet. Take 10 mins...hell takes longer to jack it up.

A flate-rate guy, and no picture of the cordless impact beating the plugs down to final torque? You took them out with a ratchet?

Fail.

Great post. Can't wait to see Moose change the oil.....


I was reading the post expecting a Mr Bill episode or something.

Moose - That is so cool, and a brilliant idea, thanks for taking the time to post it.

I'm looking forward to the next instalment - I hope we get to see you in your Snap On overalls! :)

Moose, I knew it was a joke the whole time, nobody would really need pliers to pull plug boots!

Depends on the engine. Certain VWs (VR6s) require a special tool to remove the HT leads from the plug, some of their 8-valve engines need a screwdriver to pop the lead without damage. The pliers prevent damage to the leads anyway.

VERY, VERY well done.

Adam

I'm glad you liked it, Adam. There will be more on the way. I did want to make another a couple weeks ago, but i was pressed for time and the lighting in the garage was terrible. So the Disc Brake Replacement will be covered another time. I do, however, have some pics:

Securing it with axle stands:

Removing the anti-rattle clip:

(Notice my fancy new latex gloves, i also have overalls.)

Just a teaser. :)

Hey Moose, what might this special tool look like? I'm going to get around to changing the plugs in my 2001.5 VR6 Passat one of these days, soon.
