Working on an 87.

One of the long thin cover bolts on DS looked/smelled like it was in an engine oilway. Is this typical? I don't remember this on S3's I've done.

During this job, are any bolts that need removing in oilways or waterway?

 

The only bolt that touches fluid is the right "middle" tensioner bolt. (As you look at it.) This bolt actually communicates with one if the head stud holes and therefore needs a bit of sealant. Use Loctite 574 or something equal to this sealant. Drei Bond works, too.

 

the other bolt that can leak is the front lower timing cover long bolt this one goes through one of the b securing holes for the WP if you get it out and its corroded it should be replaced.
also replace the WP bolts, Ace has those as well.
I have been using the loctite non setting pipe thread sealant with PTFE on the WP bolts and tensioner pivot and tensioner mounting bolt no leaks and they come out without corrosion
