440 Exhaust leaking???

[GassMann]

Hey all,

I installed a 440 in my 66 dodge charger. First time I have worked with a 440 block. It has HP exhaust manifolds. Runs great but I am noting steam from second to rear right exhaust bolt. Did I miss something when assembling the exhaust?

Did you use sealer on the exhaust manifold studs? Several of them go to the water jacket.

I always treat all of the studs as if they go into the water jacket, just to be safe.

I did not... simply didn't know they did. Now I do. I will pull the manifold and Permatex them in.

Drain the coolant BEFORE you take out the exhaust studs or bolts.
