Review on 🔧 Dorman OE FIX 615-380 Engine Intake Manifold for Buick/Chevrolet Models by Luis Green

If your Cruze is leaking oil or suddenly ejecting oil from an unknown location, the one-way valve in the intake manifold is worn and missing. This valve regulates the pressure in the crankcase. If the valve is missing, the engine will build up so much pressure that oil will leak out of the engine. This new improved design manifold prevents this valve from coming out. Oil suddenly leaked out of the engine compartment on the passenger side. I couldn't tell where it came from. The car is not leaking when idling on the lift. It will only leak while driving. In any case, the valve was missing in the standard distributor. Manifold and breather hose replaced. This fixed the oil leak. In fact, Dorman sells a kit for the Cruze. It includes an upgraded intake, new breather hose and upgraded valve cover. That would be the best deal.
