Just as a point of reference as to what can be done with JB Weld... the "official" procedure published by SAAB for filling pits in the block surface that sometimes occur when a head gasket fails is to fill them with JB Weld and then shave it flush after it dries. Slap a new gasket on and tighten her up.

I've never used this procedure, but apparently a lot of SAAB techs have.

Wow while I had never heard of this stuff before this thread, I dismissed its application. Whats the heat rating of it? I'll have to ask pops about it.
