    Q:
    What is the purpose of the Positive Crankcase Ventilation (PCV) system,PCV Hose and PCV Valve and how to replace on Subaru Forester? Posted by Customer
    A:
    The Positive Crankcase Ventilation (PCV) system reduces hydrocarbon emissions by directing blow-by gases and crankcase vapors into the intake manifold, where they are mixed with intake air before entering the combustion chambers where they mix with the air/fuel mixture that gets used during combustion. It does so by taking fresh air from the housing of an air filter and then routing it through a group of tubes into the crankcase where it mixes up with blow-by gases before being extracted out of this area through PCV valve via intake vacuum, which finally directs them into the intake manifold. The throttle body is connected to PCV valve and there is a ventilation hose, leading from it to a vented chamber inside the engine, such that when you lift off or close your throttle valves, vacuum created in your intake manifold pulls fresh air through both these hoses into your engine. However, at full throttle opening, there is usually not enough vacuum generated within your engine's intake manifold to be able to suck any additional atmospheric pressure inside its crankcase neither can it draw out any leftover blowby gases or even vapors from this crankcase. Instead, other conduits allow more than sufficient amounts of these two substances to escape from the engine block while ending up in either its induction pathway like cold-air pipe or even in an open-element type of air cleaner that could be contained within one's vehicle's hood; whereby all this happens simultaneously as we have mentioned earlier. It is important for one to regularly check their PCV system for clogs or damage because if this passage gets obstructed then leaking seals start happening among other things. There are easy ways of checking fresh air inlet tubes for cracks and wear; replace any malfunctioning ones found here after disconnection. A second component making up part of an emission control system fitted onto most vehicles' engines is known as your "crankcase ventilation" hose meaning that this would also need inspection as well. PCV valve, which is on a crankcase's right rear corner, can be unscrewed and substituted as necessary. One must always maintain their car's PCV system regularly so that it functions optimally as well as emits less amounts of harmful substances into the atmosphere; this guarantees effective performance since all wastes produced tend to minimize when dealt with immediately.

    Q:
    What happens during wide-open throttle conditions for the 2005 Subaru Impreza? Posted by Customer
    A:
    Intake manifold vacuum is not high enough to pull fresh air into the crankcase or to pull blow-by gases and crankcase vapors out. Instead, other hoses allow some of these gases and vapors to flow out of the crankcase and into the air intake duct or air filter housing.

    Q:
    What components of the PCV system should be inspected for the 2006 Subaru Legacy? Posted by Customer
    A:
    The fresh air inlet hoses should be inspected for cracks or deterioration, and if damaged, they should be replaced. The crankcase ventilation hose, or PCV hose, should also be inspected for damage. The PCV valve, located on the right rear corner of the crankcase, can be unscrewed and replaced if necessary.

    Q:
    How can the crankcase ventilation hose be replaced for the 2007 Subaru Outback? Posted by Customer
    A:
    To replace the crankcase ventilation hose, loosen the hose clamps and pull off the hose at each end. Inspect the hose for damage, and if necessary, replace it. Installation is the reverse of removal.
