Start the engine and remove the PCV valve from the valve cover (with the hose attached). Place your finger over the end of the PCV valve to see if it have strong suction. If so it is operating properly. If not, stop the engine and clean the hose and intake port where the PCV connects.(They sometimes become clogged). Also, make sure that the hose that runs from the air cleaner to the valve cover is not clogged. Let me know the results. Thanks.
