Coolant leak at cylinder head on rebuild....torque spec's for nuts
don46:
several years ago, I had one do the same thing, I'd gotten it from LA sleeve with a big bore kit. I called and the guy told me there was no way it was leaking through the gasket, but it was. I had 2 head kits so I slipped in the other gasket and not problem and yes it was a Cometic gasket. Since then I have used literally hundreds of cometic kits with no issues.

So I got this today....
And fixed my leak...
It was a combination of the original crappy gasket (you can see it falling apart after removing it with that copper gasket spray) and torque wrench.
I was using my 1/2 drive torque wrench but it's really made for working with 35ft lbs and more. You can't really "hear" the click. You need to feel it. So I bought a 3/8" drive torque wrench a la harbor freight, $17.00.
And I was surprised how much 18ft lbs really is. When I originally over torqued it using the 1/2" drive, I probably was a little over 18ft lbs...but not by much.
Anyway, I torqued everything down using my new gasket and torque wrench and it worked.
dinky,
