    Q:
    How to check and replace the PCV Valve on 2000-2011 Ford Ranger? Posted by Customer
    A:
    One must regularly clean and check the PCV valve and hoses to keep the PCV system efficient. The valve can be found in different places depending on the model of the engine. It should shake when you take it out and give it a good shake, or just replace it if you do not hear anything. Check if there is any vacuum after detaching the hose. If there is no vacuum it means that one should look for leaks or replace any damaged components. Ensure that the hose is clean and in good condition with necessary fittings. Fit a new valve where necessary and reconnect the hose safely too.

    Q:
    Where is the location and how to check and replace the PCV valve in Mercury Mariner with four-cylinder engines? Posted by Customer
    A:
    If the model is 2004 and earlier, then you need to start the engine and detach the PCV valve from the valve cover. Check for a vacuum at the end of the valve. If there is no vacuum, take out the valve and check if there is a vacuum in the hose. Change it if necessary. Inspect whether the rubber grommet is damaged or not. Clean and examine your hose. You should install a new PCV valve if required. For models 2005-2008, you need to remove your intake manifold and disconnect a hose from a PCV valve. Remove a valve from a crankcase oil separator. Installation will be vice versa. If it's 2009 or later models, then the PCV valve refers to one of parts of the crankcase oil separator.
