How to Replace a PCV Valve in a 2002 Dodge 1500

Dodge first used the Ram nomenclature for its full-sized pickups in 1981. In 1994, Dodge redesigned the Ram, giving it the now famous "big-rig" appearance. The 2002 model year brought about another redesign for the Ram, retaining the "big-rig" look, but enlarging the headlights and smoothing the body lines. The 2002 Ram 1500 had three engines available: a 215-horsepower, 3.7-liter V-6, a 240-horsepower, 4.7-liter V-8 and a 245-horsepower 5.9-liter V-8. All three engines have an emission control system -- positive crankcase ventilation system -- that circulates toxic gases from the crankcase into the combustion chamber for burning. The PCV valve opens and closes, as needed, to regulate the flow of the gases.

Step 1 - Find the PCV valve -- the L-shaped plastic valve --connected to the oil filler tube, just below the oil filler cap.

Step 2 - Pull the rubber vacuum hose from the PCV valve with a slight twisting motion.

Step 3 - Twist the PCV valve about a half-turn counterclockwise and pull the PCV valve from the oil filler tube.

Step 4 - Line the tabs on the PCV valve up with the notches in the oil filler tube. Insert a new PCV valve into the oil filler tube and twist it clockwise to lock it into place.

Press the rubber vacuum hose onto the PCV valve.
