Why does oil come out of the PCV valve?
Why does oil come out of the PCV valve?
The PCV valve is in the valve cover, where oil shoots up and sloshes all over the place. If there is too much oil, one of the few ways it can escape is through the PCV valve. I was under the impression that the oil might sip into the valve and through the tubes. So it’s pretty alright for oil to appear on the valve?

Why do I get blue smoke from my PCV valve?

What causes a PCV valve to blow out?
Typically the PCV valve fails due to high pressure for other reasons. I’m going to try to link to a few threads that explains the PCV valve, how it works, how to test if it’s blown, and the intake manifold. Anyone can remove the cover and test to see if the PCV valve is blown without tools.
Can you use PCV or breathers on the valve covers?
Yes, that is exactly what I did on my s-trimmed 336, and it makes over 500hp with ZERO issues. You have to be very careful on what type of valve covers you are using as far as the PCV system goes.

What’s the problem with the frozen PCV valve?
One more thing (now comes the amazing part!)… While they are doing usual diagnostic for the frozen PCV valve yesterday, they also discovered three blown oil gasket and severe oil leaks; oil pan gasket are blown, crankshaft gasket are blown and another oil gasket are blown (I can’t remember where).
Is the intake plenum clean with PCV system?
No more smoke, AND after pulling the carb to check on the condition of the intake plenum, NO MORE OILY GOO!! The entire intake plenum and all runners are spotlessly clean and bone dry. I’m not discounting a proper PCV system and believe that it is needed for cleaner engine operation etc.
