    Do you mean into the intake manifold? That is where the t-stat is. It could be leaking from there. If that is the case a new gasket should do the trick.

    Sounds like your problem is with the thermostat housing. I'd guess that the gasket is bad, but for about $10 more, I'd put in a new gasket, thermostat, and a new housing. Use a bunch of Permatex #2 non-hardening gasket sealer on the new gasket, and torque it evenly.

    I agree with Pugsley, but just want to reiterate torquing it evenly is very important. I broke an ear off once in a rush on a sunday night (no parts places open). Got nowhere real fast!

    Me too! I broke an ear off on my old dually's 454 in Monahans Texas on a Saturday night - it was a long wait till Monday morning to get a new one.

    LOL, story of my life... At least I was home, though. Sucks worse to have it happen away from home!

    Ever since that trip I've added a spare housing to my parts box - Pretty soon I'll be better stocked than most of the chain parts stores[​IMG]
