The 1997 Dodge Dakota came equipped with a 2.5-liter four-cylinder, a 3.9-liter V-6 or a 5.2-liter V-8 engine. PCV stands for positive crankcase ventilation, and the valve is responsible for relieving pressure inside the oil crankcase. The PCV valve on the 1997 Dakota can become saturated in oil and dirt over time, causing it to stick in the open or shut position. The PCV valve can also become stuck inside the valve cover of the engine if it is left in too long, requiring extra procedures to remove it.
Instructions
- 1
Open the hood of the Dakota.
2Locate the PCV valve, which is mounted into the passenger side valve cover. Remove the PCV valve by pulling it upward out of the valve cover. If the PCV valve is stuck inside the valve cover proceed to Step 3.
3Spray a rag or paper towel with penetrating oil. Wipe the upper flange of the PCV valve with the moistened rag. Wipe the small nipple where it is joined to the rubber hose on the outer end of the PCV. Allow the penetrating oil to set for about 5 minutes for best results. Remove the PCV valve from the engine by hand. Use pliers to gently rotate the PCV valve in the valve cover if needed. Do not use too much force on the valve because it is plastic and will break.
4Remove the PCV valve outer end from the rubber hose with your hands. If the PCV valve hose is severely dry rotted or cracked, replace the hose.
