Zen and the art of BMW maintenance… (plus some cheap tool cursing)
The wife was out of town for work so I took the opportunity to catch up on some much overdue maintenance on her car. The valve cover gasket has been leaking for a while and needed to be addressed. In addition, the oil filter housing and valvetronic motor gaskets were joining in on the fun so needless to say the engine was an oily mess.
While the car was apart and on the lift (love the lift!) it was time to give the suspension some love also; So new struts, shocks, mounts and control arms were also in the parts order.
Started Friday night.
Parts, lots of parts…
I worked in a shop during high school and summers during college. My old boss would be very disappointed.
Engine before…
I have wrenched on BMW’s (cars and bikes) for over 20 years and have changed valve cover gaskets on 3 series cars from the E30 to now the E90. Working on this car, and the lack of access, makes me pine for the good old days and the earlier cars with easy on/off covers and valve adjustments. I come to find out from my buddy who is a service manager at the local dealer that they get 7.5 hours book time for the gasket replacement. An entire day!
All apart; including the filter housing, belts, hoses and a few other “I should replace it while I’m here things”.
Here is one of those things… The crankcase breather tube. BMW went to the heavy use of plastic in the engine bay starting with the E46 and this car is no different. After certain amounts of time it all becomes brittle and develops leaks. It is always in places that stink to get to so while the filter housing was off I decided to change out those as well. (This little hose lives behind the cylinder head and under the intake manifold) The old one came out in pieces.
I hope I can remember where this goes…
3am…
Saturday… (Late morning start with lots of coffee)
Up on the lift! Did I mention that this thing is great? I haven’t had access to a lift since collage (early 90’s) and it makes such a difference.
New rear shocks and mounts. This one blew-up just after I pulled it. Guess it was time.
Remember that we live on a dirt road? Can you pick out the new shock and mount?
Rears are done. No drama. Nice and easy. The front was a little more trouble. First, I will say that I usually buy good professional quality tools. It has been my experience that they are worth it. It isn’t that less expensive tools can’t perform, or that expensive tools always perform, but the better tool is usually less trouble and just does what it is supposed to do. The cheap tools tend to be more hit or miss. YMMV. I loaned my tie-rod tool to a buddy who never returned it.

I purchased one at Harbor Freight for this job.
Here it is after 2 uses.
Add 2+ hours to the job running back to the store for a replacement. I should have sucked it up and ordered the German tool again and saved the headache. Lesson learned.
I purchased a strut compressor for this job. The last time I have to do springs I took them to a friends shop and used the wall mount compressor. We live an hour + each way from the shop and I decided that having the tools here was better so I ordered this.
The springs on some BMW’s and other German cars are short in length and # of coils which poses problems with these types of tools.
I knew this so I ordered the “adapter kit”. This is a reasonable inexpensive solution to the issue but the execution was junk. So, to get the adapter to work/stay in the tool I had to add some tapped holes and grade 8 bolts/washers. These springs, when compressed are storing a bunch of energy that is just waiting to do bad things to you should the tool fail.
This tool, with the adapter, runs about $260. A used wall mount is $400 around here on Craig’s List. Next time I’ll buy the real tool and save the 4 hours of messing around.
Sunday…
Picked up the wife from DIA and ran errands getting back to the house late afternoon.
2:00am and I had this…
Can you pick out the new parts? (it's kinda a game at this point, find the new parts)
3:00am and the tools were put away. The car is at the local shop being aligned as I write this from the coffee shop across the street.
Some things I was reminded of:
1. I still enjoy wrenching on these cars. A lot. The German thought process/engineering still makes sense to me.
2. The MaxJax is awesome! I had to do the final torqueing of the control arm bolts with car on the ground, weighted. 4 bolts. I spent all of 15 min crawling on my back and it made me appreciate the lift that much more.

3. Buy good tools. Cheap tools are frustrating.

4. I need more a lot more light in the garage. I worked the entire time with a head lamp on. When it comes the to "GarageJournal" the garage this spring, I'm going to add a bunch of additional fixtures.
Just got a call from the shop and the car is off the rack. Next up is my E46.
Thanks, as always, for reading through the ramblings.
Cheers,
Chris
