the ecotec does not have a pcv valve!!! the orifice in head is clogged,have to pull intake off and un-clog restriction
The PCV valve (Positive Crankcase Ventilation) might be defective or clogged open allowing oil under excess pressure from the oil pan into the intake manifold and air intake. The PVC system is designed to draw excess fuel vapors from the oil pan which gets by the rings.via the valve cover area into the intake to be burned in the combustion cycle. Worn piston rings can also cause excessive pressure in the oil pan.overcoming the pressure in the intake tract. Check or replace the PVC valve and have a compression test done to see if the rings are worn. Mileage of the vehicle?
