Engine The impossible to access 258 valve cover bolt.

[jzak]

Hey Guys,

For you AMC 258 i6 / 4.2l owners out there, wanted to get your opinion on the best way to tighten down that valve cover bolt located up against the firewall. I've got a bad track record with valve cover gaskets, so last time I had a shop do it. It sealed fine for a few years, but just recently it started leaking again. Took a closer look back there, and it turned out the mechanic never bothered putting in a bolt. He just RTV'd the hell out of it. I'm going to try replacing the gasket, but nothing I have can access that area. I bought Hex T-Key allen wrench set, which helped with the other bolts, but that S.O.B. seems impossible to get at.

Any suggestions?

Thanks!

J

I replaced my bolts with studs then used a dab of locktite haven't had any issues yet

I bought these when I upgraded my Dana 300 . These work great for i guess it’s a cap screw. Long enough and I could actually turn them by hand. I also used one of those orange silicone gasket and it’s great.
