    Q:
    What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on Cadillac DeVille? Posted by Customer
    A:
    A PCV (Positive Crankcase Ventilation) system helps to reduce hydrocarbon emissions by passing fresh air through the crankcase, which picks up blow-by gases and then pulls them via the PCV valve into the throttle body or intake manifold where they are burned by the engine. The PCV system comprises of two hoses and a PCV valve that controls the flow of gases in relation to engine speed and manifold vacuum. On some newer models, an upper intake manifold is located over a "dirty air" tube that carries blow-by gases from the crankcase, through the PCV valve and into the throttle body. One hose brings in cool ambient air from outside through an air intake duct while another takes crankcase gases out of crankcase, through the PCV valve and into a throttle body. The PCSV system can be inspected for proper operation easily. Keep checking your PCV system, as carbon black and gunk deposited by blow-by gases will eventually clog up the "dirty" side system hose and inside of throttle body behind throttle plate as well as its valve. Common symptoms for a blocked or stuck PCV (positive crankcase ventilation) valve include rough idle, stalling or slow idle speed, oil leaks, oil in air cleaner or sludge in engine. Valves for Positive Crank Case Ventilation.

    Q:
    How to remove and replace the PCV valve on Cadillac DeVille? Posted by Customer
    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 check and replace the PCV valve on Chevrolet Blazer? Posted by Customer
    A:
    If the engine runs at normal operating temperature, while idling, withdraw the valve (with attached hose) from the rubber grommet on the valve cover. In a V6 engine, PCV valve takes place in a valve cover. Take it out and see if there is any suction and shake it to check for rattles. Put your finger over the tip of the valve. If there is no vacuum at the valve, test a clogged hose, manifold port or valve itself. Replace any plugged or deteriorated hoses. Shut off engine and shake PCV valve; listen for rattle. If it does not rattle, get a new one to replace that which exists currently but doesn't make noise when shaken, and pull it out of end of hose so that you can take note its installed position as well as direction before replacing it again with an identical one To fit a replacement PCV vale, remove it from the end of hose and remember how it has been placed consequently you may have problems with finding appropriate vehicle model year, size for such an item purchased only after comparing previous characteristics with new ones Check for damage on rubber grommet and if need be install a new one. Lastly push another pcv valve and hose into their respective slots inside the valve cover securely.

    Q:
    What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on Chevrolet Express? Posted by Customer
    A:
    To reduce hydrocarbon emissions, the Positive Crankcase Ventilation (PCV) system scavenges crankcase vapors rich in unburned hydrocarbons. Rather than using intake manifold vacuum for this purpose, as it happens in the conventional PCV systems; however, the system in these vehicles does not. It is done by connecting a fresh air inlet hose from the air intake duct or resonator box straight to valve cover, which allows pressure equalization by fresh air. There is another hose that draws in crankcase vapors by connecting the left valve cover to the intake manifold. Based on intake vacuum levels, PCV valve controls vapor flow into intake manifold. The engine model determines how a particular PCV system is configured. When servicing an engine, the hoses of its PCV system should be checked for any damage or clogs as well as leaks. Rough idling, stalling, high or low idle speeds, oil leaks and sludge buildup may all occur due to blocked or leaking hoses. Vacuum presence in the PCV hose can be tested very simply checking vacuum gauge readings at different stages of running and diagnosing such problems as leaks blockages or excessive crankcase pressure which influence PCV system work.

    Q:
    How is the PCV valve accessed and serviced on Chevrolet Express? Posted by Customer
    A:
    The PCV valve is internal within the valve cover and therefore, the engine cover has to be discarded so as to access the PCV valve. The fixed orifice for 2004 and later models (except 2018-later 4.3L models) is built into the valve cover and is not replaceable, while the 2018 and later 4.3L models use a conventional PCV valve that is screwed into the top front of the left side of the valve cover. For 2003 and earlier models, with the engine idling at normal operating temperature, the valve cover should be pulled from the rubber grommet with the hose attached and will enable that vacuum check by pulling out the PCV valve. For 4.3L engines where the PCV was produced after 2018, the PCV valve comes with a hose attached, and can be unscrewed from the left valve cover. To check if there is vacuum, block the valve opening with the finger and if their is no vacuum, check for blocked hose, manifold port or the valve, and replace any spoilt hose. When the engine is switched off gently move the PCV valve to listen for a rattle; if the valve doesn't rattle then it should be replaced. For the models up to 2003 and for 4.3L models manufactured before 2018, the valve must be pulled out from the end of the hose with the attention to the position of the valve and for the models which have been produced from 2018, the PCV quick-connect fitting must be disconnected to isolate the valve from the hose. A replacement should be of the correct vehicle and engine size as the old one; the two valves should also be compared. The new valve should be driven in up to the rubber grommet and then the grommet tested for damage and replaced if the case were applicable. Last but not least, for 2018 and later 4.3L's, the PCV was supposed to be threaded into the left valve cover and tightened securely by hand, further, the PCVs were supposed to be inspected for clogs or crimped hoses before connecting the quick-connect fitting onto the top of the valve until the until an audible click is heard.

    Q:
    Where is the PCV valve located and how do you check and replace it on Chevrolet Silverado? Posted by Customer
    A:
    The PCV valve is located in the left valve cover. Pull the valve (with hose attached) from the rubber grommet in the cover while engine idle normal operating temperature. Put your finger over the valve opening. Check for a plugged hose, manifold port, or the valve itself if there's no vacuum at the valve. Replace any plugged or deteriorated hoses. Turn off the engine and shake it to check for rattling sounds from PCV valve. Replace it with a new one if it does not rattle. To replace pull out the one end of hose and note its seated position. When purchasing a replacement PCV valve, make sure it's for your particular vehicle and engine size. Compare the old valve with the new one to make sure they're the same. Push until seated into hole in end of hose . Inspect grommet for damage and hardening; replace as needed. Push securely into place pcv valve and line.
