    The front PCV was blowing oil into air filter housing and has since stopped. Back PCV has southern engineered tubing, haven't been able to get parts from dealership. Parts availability is the only complaint I have for my Jeep. Almost everything has to come from Dodge-Chrysler dealership, no aftermarket. Thanks for solution, I'll check it out.

Sounds like you have one or more faulty compression rings. This is not a DIY job and will be costly. What does the oil pressure gauge read?

1992 cadillac deville leaking oil at dipstick

I would look for other leaks. If you are sure it's leaking at the dipstick tube, there is normally an o-ring where the tube presses into the engine. In general, this is an odd place for a leak, as ther eshould be no oil pressure in the pan (where the tube terminates) and unless the engine is overfilled with oil, the tube end shouldn't be immersed in oil to leak. IF there is pressure in the oil pan, that generally indicates bad rings. I have seen engines where the oil dipstick actually pops out of the tube under pressure when the engine is running due to pressure in the oil pan from blow-by at the rings.

My 1996 jeep grand cherokee oil dipstick tube has vacuum

The PCV system is supposed to pull vac on the crankcase to re-burn the fumes in the oil pan.
But your engine sounds like it has a vent problem via the air filter.

3.0 jeep grand cherokee poor starting.changed heater plugs but vehicle still turns over quite a while before firing on a morning.once started it is fine rest of day.

Oil Heater,,,the auto parts stores have an heater tube you insert into the dipstick tube,,,its a cheap fix,,usually about 20 dollars,,,keeps oil warm and provides quick starts,,,other fix's are expensieve,,so this is the lowest cost method. good luck. Tim.

Need a picture of oil pump for 1993 cherokee straight 6

Jeep Wagoneer/Commando/Cherokee 1984-1998 Oil Pump - Removal & Installation
2.5L and 4.0L Engines
(see Figure 1)
  1. Disconnect the negative battery cable. Raise and safely support the vehicle.
  2. Drain the engine oil and remove the oil pan.
  3. Unbolt and remove the pump assembly from the block. Discard the gasket.
WARNING If the oil pump is not to be serviced, do not disturb the position of the oil inlet tube and strainer assembly in the pump body. If the tube is moved within the pump body, a replacement tube and strainer assembly must be installed to assure an airtight seal.
To install:
  1. If a new pump is being installed, prime the pump by submerging the strainer in clean engine oil and turning the pump gears until oil emerges from the pump feed hole.

Fig. 1: Oil pump inlet tube installation
  1. Using a new gasket, install the pump on the cylinder block. Tighten the short bolt to 10 ft. lbs. (14 Nm) and the long bolt to 17 ft. lbs. (23 Nm).
  2. Install the oil pan and lower the vehicle.
  3. Fill the engine with the proper type and quantity of oil.
  4. Connect the negative battery cable. Start the engine and check for proper oil pressure.
Hope this help (remember comment and rated this).

Need to know how to check oil in transmition in a 95 ford aspire

Check the engine oil level every time you fill the gas tank. The car should be on level ground when checking the oil.
  1. Turn the car off and wait several minutes.
  2. Locate the engine oil dipstick and withdraw it from the tube.
  3. Wipe the dipstick with a clean rag and reinsert it in the dipstick tube.
  4. Remove the dipstick again, hold the dipstick horizontally and observe the level of the oil.

Fig. 1: Grasp the engine oil dipstick and withdraw it from the tube

Fig. 2: Observe the oil level on the dipstick and add oil if it is low

  1. The oil level should be at the FULL mark on the dipstick.
  2. If the level is at or near the LOW mark, replace the dipstick and add fresh oil to bring the level up to the FULL mark. Do not overfill.
  3. Recheck the oil level and close the hood.

Good luck, and remember rated this help!!!

Oil blowing out of the dipstick tube.

On top of the valve cover there is a fresh air breather unit. Make sure the breather unit is not plugged.
Also the fixed orifice PCV should be clear. Find a tool that will go through the orifice and make sure it is clean.
Remove the vacuum hose and check it for cracks or internal damage. With the engine running, make sure you have vacuum through the hose.
Let me know when your finished cleaning the crankcase breather system.
