1995 Nissan Truck PCV VALVE

The pcv valve on the 2.4 l engine is located behind the alternator and the engine oil filter. The best way to change it is to go thru the wheel well. Take off the passenger front wheel, lift or remove the rubber splash curtain, remove the oil filter, disconnect the rubber vacuum hose, then use a 19 mm wrench to remove the pcv valve. I've found it easier to remove the two 10 mm retaining screws of the bracket that is securing two metal lines and an electrical connector for a little more accessibility. Changing the oil at the same time you do this is highly recommended for your convenience.
