Piston Engine Models: B2000

With engine at normal operating temperature and key off, remove hose from PCV valve. Run engine at idle and place finger over the PCV valve inlet. If idle speed does not drop, replace PCV valve.

NOTE: To replace PCV valve on California models with automatic transmissions and on all Federal models, first remove carburetor. Carburetor removal is not necessary on other B2000 models.
