Cadillac PCV Valve Parts Questions & Experts Answers
- Q: How to remove and replace the PCV valve on Cadillac DeVille?A:Lift the engine cover and with the engine running at normal temperature, pull the valve accompanied with the hose off the rubber grommet in the valve cover. Depress the end of the valve and, if there is no vacuum, then look for a plugged hose, manifold port or the valve; replace any bad hoses. When the engine is running, unscrew the PCV valve and check for suction at the end; when the engine is switched off, shake the valve and listen to the rattle noise. Switch off the engine and again try shaking the PCV valve; if the sound is not of rattle then take a new one. To replace the valve simply unscrew or slide the valve from the end of the hose remembering which way it was installed. Always ensure you get the correct PCV valve for your car, especially in regard to the model year and the engine size; compare the old valve with the new one. Insert the valve well into the end of the hose to engage the rubber grommet, check the condition of the grommet and replace if required. Finally lock the PCV valve and hose firmly in the place in the valve cover and fit the engine cover again.
- Q: How to Replace the PCV Valve and Hoses on Cadillac Escalade?A:The Positive Crankcase Ventilation (PCV) system reduces hydrocarbon emissions by scavenging crankcase vapors and burning them along with the air-fuel mixture. It utilizes a PCV orifice for 6.0L models or a PCV valve for non-6.0L models, which are threaded into either the rear of the left valve cover for 4.3L V6 or below the throttle body in the intake manifold for 5.3L and 6.2L V8 engines. The system includes two hoses: the fresh air inlet hose carries outside air from the air intake duct to a pipe on the right valve cover, mixing with blow-by gases and crankcase vapors in the crankcase. These vapors are drawn through the orifice or valve, then into the intake manifold to mix with incoming air. For replacement, note that the procedure does not apply to 6.0L VB models, as the orifice is part of the driver's-side valve cover and is not serviceable separately; if clogged, the valve cover must be removed for cleaning. For 4.3L V6 models, the driver's-side engine cover should be removed, and for 5.3L and 6.2L V8 engines, the intake air duct must be taken off. Disconnect the hose from the PCV valve and use a socket to unscrew the valve from the engine, then reverse the removal procedures for installation.
