OPERATION



A closed type crankcase ventilation system is used to prevent engine blow-by gases from escaping into the atmosphere.

See the accompanying illustrations for PCV valve location.

SERVICE



To check for a clogged PCV valve with the engine running, remove the valve from its mounting. A hissing sound should be heard and vacuum should be felt from the inlet (bottom) side of the valve. Turn off the engine, shake the valve. A clicking sound should come from the valve when it is shaken. If the valve fails either of these tests, replace it.

REMOVAL & INSTALLATION



Remove the valve from its mounting. Disconnect the hose from the valve. Install a new valve into the hose and push the valve into the mounting.
