This PCV valve in Cadillac Escalade vehicle is very important in increasing the performance of the engine and at the same time minimizing the emission of the undesirable gases. This component recycles partially burnt gases from the crankcase back to the combustion chamber for their safe combustion. As such, the Cadillac Escalade's PCV Valve prevents oil from becoming tainted with heated vapors detrimental to the engine and further, it reduces sludge build-up. Functioning through variation with the intake manifold vacuum, PCV valve regulates the processes of gases for higher and optimal performance of the engine. It closes to limit flow at idle to avoid a lean situation or opens up under higher revolutions to cater for augmented blow-by gases. Also, it acts as the flame arrester as it prevents pressure build up on the crankcase in instances of turbo charges or back fire. It is advised that the PCV Valve should be checked often to prevent damages which are expensive, as a result of the malfunction, such as oil leaks and high incidence of fuel consumption.
