Before you give your mechanic the go-ahead and
"open your wallet", a couple of comments:
- I had a similar problem with my '90 M-30 motor
with over 100k and "the cover bolts were loose".
Check the bolts....I tightened mine and the leak
went away. Put the front of the car up on ramps
and go over the whole motor....10mm bolts on
front and go around the oil pan. These do work
loose over time creating misc leaks. Shouldn't
have to go thru expense of replacing gaskets.
Also adjust the valves and "replace the valve
cover gasket"...$12
- The timing chain should last 200-250K no
- While you are checking timing chain cover bolt
torques...clean the RPM/REF sensor located on
the Pass sd. off the front pulley/damper.
Clearance with the damper should be set to 1 mm.
- Order parts thru Bavarian Autosport
1-800-535-2002. Pagid pads aren't that expensive
and are worth the money. Talk to Bav Auto.
- In general, be very cautious about mechanics
advise. 1.3K seems very heavy for fixing a
timing cover leak. Use this board and get second and third opinions. If you can turn a wrench a
little, can save you big money. Defer big jobs
to an expert after thorough investigation.

Best Regards,

I brought my '91 535ia to my mechanic today, he put it up on the hoist to check everything out. Unfortunately he found there was a small oil leak coming from the front engine seal. He told me that it was a pretty major job and required the timing chain to be changed at the same time, the parts and labor would be about $1300 US (does this sound right?) Does the chain really need replacing? Can I do this job myself with a Bentley manual, some tools and some patience? I also have to do the brakes (pads and rotors) can someone let me know where is the cheapest place to get parts? Are the pagid pads worth the extra expense? or should I get metalmaster, deluxe or other? all opinions would be appreciated. Thanks in advance for the help.
: ps. I want to get new tires for my stock 15" wheels, any suggestions? I live in Vancouver, B.C. (alot of rain, very little snow)
