Hey I have a 1990 GT. Just yesterday I took it for a ride and when I got back, I popped the hood to find white smoke pouring out from the vents of the oil cap. When I took the cap off, there was a white sludge builtup (similar to an oil/coolant mix or condensation problem that most dodges have). I checked the oil and the coolant and they are both clean. I did headgaskets on it less than 2 months ago and replaced just about every gasket in the top end.

PCV valve and screen are both clean, and the exhaust isn't smoking abnormally. This happened all of a sudden, It wasn't gradual. Im kind of out of ideas at this point.

Intake shouldn't have any leaks, I put all brand new gaskets including valve seals when I did the headgaskets.


I haven't changed the oil since I did the headgaskets. The oil that's in the car now is clean.

I think ill pull off the valve cover on the pasas side next and see if I can get a better idea where the smoke is coming from.
