The first time when it ran really hot it had to damage the headgasket or warp the head.. I mean the oil was so hot it was barely holding oil pressure resulting in valvetrain noise. It didn't run very long like that so hopefully nothing is damaged internally. The Blue Devil did stop it from steaming out the exhaust; however, I know that it cannot permanently fix the problems I have. I'm hoping that it will only take a couple of head gaskets to fix instead of the heads being warped. Wouldn't you say the gaskets would blow or burnout before the heads would be warped? And if the heads were warped, wouldn't you think the motor would skip more than being just a little rough?
    Usually head gaskets go becuase its warped. OR lifted basicly a temp. warping issue.
    Might ought to pull the heads and check it out before something expensive lets go?

    I took the t-stat out to run the Blue Devil treatment, but I put it back in after I was done.

    So your saying chances are my head gasket blew because my heads are warped?
    Or because the gasket itself is warped?
