supposed to be good for minor water leaks...

anyone used it? can recommend? stay away from it?

got a minor leak between one head and the block... both were decked and leveled as part of overhaul.  using steel head gaskets... maybe a different type gasket would be more "forgiving" and seal better??

I just hate to take the head off (and all that goes with it) if something like this product might do the trick...

only thing is that it says "do not use w/antifreeze"... no real problem here in S Texas, but would appreciate anyone's 2 cents...

thanks,mark

I don't know anything about that product but I leave those sorts of things for "fixing" an engine that is soon to be rebuilt. Since it has been rebuilt, I would go ahead and fix the problem. You need to use some sort of sealer, such as copper coat, on the steel gaskets. Even then, some milling machines don't produce a smooth enough surface for a good seal. Did the block and heads get a clean-up cut? A composition gasket will seal easier but may not be favorable if the piston to deck clearance is not close to 0.

Have you pressure tested the coolant system to pin-point exactly where the leak is originating from?  Unless you have verified that it is not one of the intermediate intake manifold studs leaking at the head, then that could be an easy fix if that is all it is.  If it is indeed leaking at the head gasket, then a composition gasket is more forgiving than the steel shim type in regards to irregularites in the deck and/or head surfaces.

 

Regardless of what you find, you’ll definitely want to run antifreeze or some form of rust inhibitor in these older engines as rust pitting from the water jacket side in both the heads and blocks is a problem when using plain water.

never use any of that stuff that claims to fix stuff that you just pour in to engine/transmission/radiator etc. not even when you are about to rebuild it, it might leave so much residue that can completely ruin the engine and parts, only when you are about to completely trash it. these method of repair is less then half ass.

don't hold back now... lemme know what you really think!!

agree with you though... I'd rather not do it the "easy" way when I could spend even more time bustin' knuckles and checking a head by taking it off one more time to make sure its right...

hey, driving is overrated anywhay, right? its the working on these things that's the best... driving it will only get the paint messed up!

thanks for the backup...
