Cam Cover oil leak
I have a cam cover bolt on my 93 that has started to leak, Is it as simple as just removing the bolt and replacing the dowty washer/seal? Its one right above #1 plug wire boot so easy to get at.

Re: Cam Cover oil leak
Well a 200 mile trip, was still seeping a bit, So this time I replaced the bolt washer and put a dab of sealer on it.... Time will tell.

Re: Cam Cover oil leak
A clogged PCV system could cause Oil leaks in lots of places including the Oil Pan and Cam Covers and the Cam Cover Vent.

Re: Cam Cover oil leak
If in a hurry loosen it up enough to put three or four wraps of teflon tape under the bolt head and retorque

Re: Cam Cover oil leak
Thanks, Its just the one bolt above the #1 plug. No hurry I just redid it this AM, I did notice this time the rubber part of the washer protrudes more on one side than the other, so put it up this time against the bolt head also cleaned the seat area with 320 wet/dry to be sure it had no burs.

Re: Cam Cover oil leak
Fixed.. Went out today for a 2 hour drive no leak! Turned out to be the O-ring on the PCV line at the cam cover going to the TB. I just kept finding oil just under the plug area.. Old one was hard as a rock.
