Oil inlet check valve. Porsche 911 65-71  ❭  RS-29A

Oil Inlet Check Valves eliminate oil migration from the oil tank to the engine reducing excessive smoking on start up typical of cars that sit for long periods of time.



Fits:
Porsche 911 1965-71

For freshly rebuilt engines, do not install check valve until first oil change.
Before installing, start your engine and verify/ reference your oil pressure. Drain oil from the engine and oil tank. Remove the rubber oil inlet hose on the right side of the engine directly behind the #6 cylinder. Cut a 1.5" piece out of the center of the horizontal section of the hose. Install the check valve with the correct orientation and tighten the clamps. Reinstall the hose and refill engine oil.
Check your oil pressure gauge when you start your engine and verify pressure.
Note: the valve is clearly marked with an engine side and a tank side. Failure to install the check valve in the right orientation will cause oil starvation and catastrophic damage to your engine.
