This video goes over how to replace a PCV valve on a 2013 Nissan Altima with a 2.5 four-cylinder. This should be the same process for any 2013- 2017 Nissan Altima with a 2.5 motor. PCV stands for Positive Crankcase Ventilation. A PCV valve controls emissions. Essentially, it takes gas produced by the motor and routes it back into the combustion chamber to be burned without harming your vehicle. If the valve doesn’t open and close on schedule or if any part of the system clogs, the result can be rough idle, sluggish acceleration or increased oil consumption. The PCV system allows for cleaner exhaust, prevents blow-by at seals and gaskets and removes crankcase gas generated by the combustion process that would sludge up and destroy the engine if left unchecked. It also allows the engine to perform better, run more efficiently, which produces better fuel economy. For whatever reason, PCV valves are usually overlooked and neglected and really should be part of your normal routine maintenance at least every 50,000 miles.
