Thanks! | | | | | Joined: Sep 2000 Posts: 67 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2000 Posts: 67 | Yes, I think it is the two outermost front and back ones that need to have sealant, but it won't hurt to put it on all of them. I bought a jar of Permatex thread sealant with teflon when I did my heads and it worked great.

Secondly, on some engines one headbolt is machined to allow oil flow? Wouldn't a bunch of thread sealer leak down there?
