Believe it if not the under carriage of this jeep is extremly clean so if there was a leak I would be able to see it very easily...I have crawled all over,under that jeep trying to figure it out and have seen no leaks...what is a leak down test?

 

Google it. I'm tired.

 

Are you serious? Your Jeep eats/leaks out a quart a WEEK? In my 55+ years, I've never seen a vehicle consume that much oil. There is no way it could be burning that much and still run. It's leaking somewhere, and it would benefit you greatly to find the leak before you ask the group about solutions.

 

K...thanks

 

A quart every 300 to 350 miles is alot.

 

I understand its a lot of oil to lose thats why i posted the question,but im going to really get into this jeep tomorrow to try and find a leak of some sort...like previously said it has to be leaking from somewhere i just havent found it yet...

 

I'd expect to see smoke with that consumption. You might have someone follow you.

Sometimes when the intake valve seals are shot you will see a cloud/burst, of smoke when you first start it after parking hot. After 1/2, 1 hour might be good. Overnight oil that ran down past the seal might have gone on down past the rings.

Might check your plugs, see if the color, (blackness), is even, and X2 on a compression test.

 

You are correct sir haha

 

I would have to disagree about it still running (but I also think there would be clear sign of where the oil is going). I just pulled my 4.0 with 290K on it and it had full power from what I could tell and I would loose a quart every 20 miles it was spitting it out of dip stick tube burning threw exhaust pretty much every orifice it could make it out. Cylinder 6 was the cause but it had full power.
Here are pics of what I found when tearing it down.

 

I would just change your oil to Valvoline MaxLife to fix the seals and oil consumption, haha

But seriously I would check every fluid you have for the presence of oil contamination along with a complete degrease of the engine/trans by hand if necessary and then look for any signs of a leak, including by the firewall. Also like has been said, plugs could tell the story.

My guess is blow by and it's smoking more than you realize, I hope it's something simple for ya though.

 

Thanks guys for all the help I'm going to really get into her today and also going to follow my wife around just to see how much the jeep is really smoking.

 

be sure to replace your PCV valve... if that is clogged it will suck oil and soon cause leaks.

 

HAHA too tired to do others work for them??

 

Yep. That's "tired"!

 

I run rotella 15w40 during the summer months. No more oil usage
