I still can not find this basted PCV valve. Dodge has hidden it well or it's so obvious I'm just plain over looking it. Last resort may be to reference a Chilton's repair manual. Appreciate the feedback fella's. Thanks.

Hi there, recently replaced the PCV valve on my 2005 Dodge, it was located on the side of the oil filler neeck,just below the cap. Hope this helps.:smileup:You have to twist and pull to release it, then twist and push to locate the new one. For me it was only a $9 part.

The Positive Crankcase Ventilation (PCV) valve is an important part of the engine. The valve provides additional air intake into the crankcase while circulating unburned gases to prevent back pressure. Cadillac developed the first PCV valves but released the design publicly. All vehicle manufacturers, including Dodge, use similar designs. Locating the PCV valve on the Dodge Ram 1500 follows the same process as for all other vehicles. The precise location depends upon the engine and the manufacturer.

Step 1

Trace the air intake hose, the large tube coming out of the air filter housing, from the housing to the PCV valve. The PCV valve connects to the intake hose after the air filter.

Step 2

Trace any vacuum tubes coming off of the intake hose. The tubes will be black rubber about a quarter-inch in diameter. Most vehicles will only have the one. Some will have two. The vacuum tube will lead you directly to the PCV valve. The tube may route through the brake booster along the firewall.

Step 3

Pull the tube off of the PCV valve to verify you have located it properly. The valve on the 3.7-L and 4.7-L engines will be on the side of the oil filter housing. The 5.7-L valve is on the intake directly behind the throttle body. The 3.9-L, 5.2-L, and 5.9-L follow standard layouts and place the PCV valve on the valve covers directly. Newer engines may place the valve in a different location.

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.

Step 5

Press the rubber vacuum hose onto the PCV valve.
