2007 Jeep Grand Cherokee drinks oil


Topic starter

2007 jeep grand cherokee, 3.7 liter, 151,000 miles, automatic. Vehicle runs great, driven daily, No codes, no driveway stains, no excessive smoke from exhaust. I have to add 2-3 quarts of oil between regular 3000 mile oil changes. Where is all this oil going?

Does the inside of your tailpipe have oily residue?

Well if it was leaking it would be dripping all over the place so it's burning it. Normally that's Warren piston rings which cars cost a fortune to rebuild the engine. But you could change the cheap little PCV valve and pray that stuck open that's the only other alternative


Already answered this one but mainly it's Warren piston rings you can do a compression test to see how worn they are do a wet and dry compression test
