Re: thermestat housing leak
where are you getting the gaskets? i noticed that O'Reilly's gasket is not a very good fit, whereas AutoZone's seems to be perfect. That O'Reilly one was so bad that I didnt use it, I used RTV soley and it worked fine. I've done that on several occasions, and it seems to work as well as anything, just go easy on the bolts so that you dont squeeze it all out. One other thing to notice is that coolant will pool right behind the gasket area inside the engine, and if you're leaning on the core support that coolant will spill over and get the sealing surface wet. It will NOT seal if this happens while you're reattaching the outlet housing! Been there, done that. I get in there with some shop towels and wick it up before I seal it back up, that way there's no chance of ruining my seal. good luck.
