Tricky-Ricky Posted July 5, 2016 Share Posted July 5, 2016 I presume you mean the PCV valve, if you mean the one with the ball valve in it, its on the left side at the front end of the cam cover, and the pipe connects to the plenum, it highly unlikely that this would be the cause of high oil consumption, due to the fact that the system works but pulling oil vapour/blow-by into the plenum, if this valve is blocked it wont pull any oil through, and if its stuck the result is that as engine revs rise, the plenum depression lowers so the same result. If you have high oil consumption, and don't have the rev-up engine, then i would first run a compression test,and go from there, its more likly to be a ring/bore seal problem, has the engine got a high mileage and no full service history?
