PCV System: Maintenance

Every 15,000 miles or every year, visually inspect rubber hose connected between air cleaner and valve cover for damage or plugging and clean hose.

Ensure that hose is clear by removing end at valve cover and blowing into hose. If hose is obstructed, remove hose and soak it in solvent. Scrub inside of hose with a long brush and dry with compressed air. When reinstalling hose, make sure all connections are tight.
