It is possible that your PCV Valve is not functioning as well as it should,,,also,,it may be that your engine has excessive wear in the piston rings and lower oil rings,,causing excessive blow by into your engine crank case.
This will of course affect how your engine runs and how much oil is consumed.
Check PCV valve and replace as neccessary.
If this doesnt work,,i'd suggest taking it to a mechanic.

What causes water blow back in 1999 4.7 grand cherokee after starting

Sound like a head gasket is leaking. The coolant is leaking from the water jacket through the failed gasket in to the engine crankcase. The "blow back" is caused by the combustion inside the cylinder to leak into the water jacket, pressurizing it.
Drain the oil immediately and do not attempt to run the engine until you have the gasket replaced. Water in the oil will destroy the engine beyond repair.

Oli leaking 1990 yj

Look for leaks high on the engine, like valve cover gaskets...

High oil pressure, if you actually had that, would not necessarily exit the engine....Crankcase pressures are not related to system pressure, per se.

Get a mirror and inspect very carefully.. Sometimes you have to clean the engine and test again, as air blows leaks all over (while driving...)

I have a 1990 Jeep wrangler and the oil pressure is off the charts, it is so high that it ruins the filter and blows oil everywhere. will changing the oil pump fix the problem or create more?

Sounds like the oil presure relief valve is stuck closed. I do believe the valve is built into the pump but I would ask when buying a pump.

94' jeep cherokee laredo..white smoke when i'm parked or stopped

Your Jeep is Burning Oil. Do you need a Quart every Now and Then? The only way to fix this is to get the Piston Rings Replaced and is not Cheap. There are a Few Additives on the Market that you can put in the Motor to Minimise the Problem for a While. You need to go to Your Auto Parts Store and see what is available in your Area on these though. Please Rate My Response! Thanks!

Jeep grand cherokee 2001 problem

See if the oil is above or below your valve cover. If it is above, clean your CCV and replace CCV gromet. If it is below, replace your valve cover gasket. If you really can't tell, spray carb cleaner on the engine when it is cold. Spray from top down and make sure it is clean in the area around the valve cover. Now watch where your oil is coming from and follow steps above.
