I have one of these cars too, also 3.5. I purchased with 34K and has used a quart of oil every 1000 miles since then. It has no leaks or smoke or any other signs of oil consumption. So much research, nobody knows why these engines do this, some have gone as far as contacting Chrysler just for them to say, " that's normal". But here is the diagram for the PCV:

Crankcase oil


You didn't mention the year of the car, but it sounds to me like a faulty PCV (positive crankcase ventilation) valve. They do tend to give out as a car ages and should be replaced periodically as part of normal maintenance. This valve is designed to ventilate oil vapor from the crankcase into the intake to be burned instead of being vented into the atmosphere. A small amount of oil in the hose running from the valve to the intake is normal, but if there is a significant quantity it could be a bad valve, or it could indicate an over-filled crankcase. In either case, remove the valve, spray some carb cleaner inside it and shake up & down until you hear the internals of the valve moving freely. Drain the cleaner and re-install. Sometimes this will do the trick. If the oil persists in collecting in the hose, replace the valve.

Where do I find the pcv valve on my 97 explorer


On a 4.0L or 4.6L V-8 engine, the PCV valve is on the back of the engine. Follow the black hose running to it just below the coil pack. On Explorers with a 3.0 L V-6, the PCV valve is on top of the engine on the right-hand side valve cover, installed in a rubber grommet with a black rubber hose running to it.

Location fo pcv valve on 2001 ford ranger 4 cyclinder 2.3


I think it is in the valve cover. see illustrations from shop manual.



Positive Crankcase Ventilation System Overview The Positive Crankcase Ventilation (PCV) System (Figure 132)cycles crankcase gases back through the engine where they are burned. The PCV valve regulates the amount of ventilating air and blow-by gas to the intake manifold and prevents backfire from traveling into the crankcase. The PCV valve should be mounted in a vertical position. On some applications, the PCV system is connected to the evaporative emission system (refer to the VECI decal). located on the underside of the hood or on the radiator cooling fan shroud.

To much pressure in the crank case.


try changing your PCV valve. Go to your nearest parts store and they will show you where it's located. If you have an autozone near by they will give you a free printout with a diagram.
