I have been chasing a small oil leak, thought it was distributor seal, so installed new one however still getting oil in on the timing cover where the hold down is bolted. Is there a washer or other gasket that goes with hold down? Small leak just can’t seem to find source, any ideas?
I'm not a big fan of the rubber valley end seals, they get crushed and cut and split....especially ifvthe heads and block have been cut
UPDATE (if interested) so i just added some UV dye to oil went on a nice little drive to see where this oil is coming from. Sure enough it is from the bolt of the distributor hold down. added some photos as well. Ordered a new one from TA with a washer, might add some thread seal or tape when i install new one.
Huh, I would use the old bolt and just teflon tape the part of that passes into the timing case? Be careful with anything you use to make this seal so "extra" material does not end up going into the timing case. Seems like an odd place to leak. Do you have an oil pressure gauge and if so how does that look?
agreed very odd place, i have a gauge but my sensor went out so i need to reinstall a new sending unit for it. but last time i had positive pressure around 30psi+
I had a front cover that had an oiling mod done. Small copper tube tapped into oil feed line and curved to squirt onto distributor gear. Yours have this done and the tube sprung a leak? Just a thought.
