Where is the PCV valve?

Where is the PCV valve on the Ecotec engines?

On the V6s I used to have, they were tucked under the back of the injector plenum.

There is a PCV hose attached to the air cleaner assembly, so I would have assumed there would be a valve in there somewhere.

Oh don't ass u me.

The hose you call a PVC hose is a fresh air (filtered) supply to the crankcase. The crankcase vapors leave through a positive crankcase ventilation (PCV) orifice in the cylinder head directly into the intake manifold. If abnormal conditions occur, the system is designed to allow excessive amounts of blow by gasses to back flow through the vent hose into the intake system to be burned in normal combustion.
This system is the same for both the 2.2L and the 2.4L engines.
