Positive crankcase ventilation is what “PCV” stands for. Your motor oil is located at the bottom of the engine in your vehicle’s crankcase. This mixture is then pumped back out through the intake manifold and into your engine’s combustion chamber.

What happens if PCV valve is blocked?
If the pcv valve or the hoses are blocked, the crankcase will push up oil into the combustion chambers, which will cause oil to burn inside the engine and go out through the exhaust pipe. A lot of blue smoke will come from the intake and exhaust system.
If you have an aftermarket exhaust manifold, you will need to replace the valve cover gasket with a new one. You can do this by removing the old one and replacing it with one of the new ones that come with your exhaust manifolds. If you don’t have one, then you can buy one from your local auto parts store.
