The Positive Crankcase Ventilation (PCV) system is an emission control device that reduces hydrocarbon emissions by scavenging crankcase vapors rich in unburned hydrocarbons. The PCV valve regulates the flow of gases into the intake manifold based on intake vacuum. Inspect the PCV system hose for damage or obstructions when servicing the engine. A clogged or leaking PCV hose may cause rough idle, stalling, low or high idle speed, oil leaks, or sludge buildup. To check the PCV system's functionality, disconnect the PCV hose, check for vacuum, and run the engine at 1500 rpm with the fresh air inlet hose pinched off. Correct any issues with the PCV system, and if there's evidence of engine oil in the throttle body or air filter housing, have the crankcase pressure tested. Excessive blow-by might indicate other underlying issues that need to be addressed.
