Blow-by gases can mix with oil vapors in your crankcase, contaminating your oil and creating sludge. Your positive crankcase ventilation (PCV) system gets those gases out, recirculating them for combustion. The system may need a source of fresh air, preferably free of dirt and debris—that’s where the valve cover breather comes in!

Moroso one-piece push-in valve cover breathers are designed to drain oil trapped in their foam filter elements back into the valve covers, rather than allow it to drain out of the air vents or get into the air cleaner. These breathers are available in several colors and finishes. They'll fit all Moroso valve covers, as well as any other covers with a 1.22 in. hole. Some have 90 degree nipples to feed vapor into the air cleaner, and an installation grommet is included.
