Does the oil light start blinking when you are idling or driving? When was the last time you changed your oil? level is good? oil is clean?
To check your PCV valve, with your engine running take off your oil filler cap and put a plastic bag over the opening. If you feel suction trying to pull the bag into the crankcase, your PCV is good. no air suction = faulty PCV.
Have you checked for oil leaks?
