Message Yeah bonez....

When I got the motor apart doing the headgaskets, I found evidence of water contamination in those two cylinders which led me to believe that originally, that gasket had been sealing except under high boost. If that's the case, chances are it started very small, and got bigger as time went by.

The directions for those gaskets say that you have to polish the mating surfaces to almost a mirror finish (50 ra or finer iirc). I don't think I got them shiny enough.
