318 head gaskets and water jacket holes

solracmopar said

Guess I can start with pulling out the exhaust to manifold bolts and re- apply rtv those 4 bolts. I never rtv'd the intake bolts. Badsport - do you happen to know which intake to head bolts have water jackets? I'm really hoping I don't have to tear the heads off again. Damn leaks.

On a side note - Thanks for the quick response guys. Having your input sure helps.

I'm not saying RTV the intake bolts, there is a water port front and rear on the intake side of the head, I usually put some kind of RTV sealant on both sides of the intake gasket around those ports. The rear doesn't pass through the intake but is still open into water.

As far as the intake bolts, I usually use Hi Temp thread sealant on those, all of them.

Before you pull the heads, have someone pour while you watch. Check around the rear exhaust manifold stud as Tony mentioned, the front and rear manifold studs go into water and have been known to leak. There should be some Hi Temp thread sealant on those as well.
