Ok I replaced my HG and got everything back together and fired it up(eventually). However, i have some white smoke coming from the exhaust in the engine bay. The smoke is coming from the flange right after the headers(header to downpipe).

I used some PB blaster on the nuts to get them free, that was like 2 weeks ago now(slowest BHG repair ever). I figured 2 weeks sitting would dry it all up?

The smoke really starts to get going after the car has been on for more than a minute. After turning the car off the smoke still seeps out for a few minutes. I cranked down the 3 bolts on that flange so i dont think its exhaust gas leaking out, unless i have a bad gasket.

Is the smoke the PB blaster burning off or is it more likely a leaking exhaust gasket?

On top of all that, the motor runs Really ruff at idle. Im pretty sure its a vacuum issue and not related. I cant tell though if its an exhaust leak causing it to run ruff or just oil buring off the flange studs.
