I have the 3.8L engine. I am getting fresh oil dripping from the upper
part of the pcv tube (near the IAC). The PCV valve appears to be doing
its job, but I am going to change it anyway. There does not seem to be
much blowby, at least with the simple removal of the oil cap trick and
there are no leaks around the valve covers that would indicate positive
pressure there. Snooping around the usegroup, I see several issues
being mentioned that might relate. The first is a baffle that prevents
oil from being sucked into the pcv valve. Is this really possible?
I'll take a look, but I'm not too keen on this being the problem. I
understand that this oil could affect some of the seals in the intake
manifold which could lead to driveability problems. I am not
experiencing this at this time. Another reason cited is the presence
of vacuum leaks. Problem is, where do I look for this?
The car otherwise drives perfectly and there are no codes on the
computer. The only symptom is this oil dripping from the upper pcv
