Ok, I found the source of the constant wet bottom of the block...I was thinking that it was the push rod tubes, so I replaced all O rings...it wasn't.
After pulling the heads, I noticed that the holes for the head studs that are inside of the valve covers were wet. AAHHHH!!! There is no seal on the flat washer, generally you don't use seal on head bolts, so, what do you all use to prevent the weepage around and under the washer? I am thinking a non hardning permatex below the washer and teflon thread seal on the studs... Thoughts? herb |

Did you check the torque on the head bolts before you removed them? Sounds like they were loose which "could" cause an oil leak, but that would also cause a major compression leak.

Hi Herb,
I've never heard of a leak there. You could do a couple of things. Something like hylomar would work there (non hardening sealant) or you could put in a little chamfer and use an o-ring. I wouldn't expect anthing to get by the threads though. Were the nuts tight? Matt |

Ok, sounds like a rare place to leak.....
The head nuts were tight, I did not check touque. It was not a lot of oil, just enough to coat the underside of the engine and hold dirt. I would get a few spots under the car all the time.... I think that a little sealant should do the trick..... thanks, herb |

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
I use a very thin smear of black RTV under the washer. Must be 100% clean of oil.
