2009 3.8 Where's my oil going?

I've read all about the oil consumption issues with this motor, but I'd like to delve a little deeper into the issue at hand. My motor seems to be consuming ALOT more than most, 1QT/250 miles. I have no leaks on the ground, the plugs are not fouled and have no smoke coming out of the tailpipe. I've checked for leeks around gaskets and have found nothing.

I did a full Seafoam treatment twice to no avail, not even a smoke show.
I've changed out the PCV valve since it was spitting oil into my air filter. I run 10W30 HM oil. Still the consumption continues.

So I'm just wondering where exactly it's going? I would assume out the exhaust, but it isn't smoking or anything of the like.
I will likely end up having to rebuild the motor but until then, I'll keep pouring oil in her and change the filter every 5k.

Try 5w-20 like the cap says. I use this in my 08 and have never had the oil burning issue. If this doesn't work I would guess it has to be coming out of the exhaust unless a ghost is stealing it.

Also just for schitz and giggles, what is the compression in each cylinder?

Initially, 5w20 was in it from the dealership. I bought it used a month or so ago. I checked the oil when I got it and it was full. I checked the oil 2 weeks later and found nothing on the dipstick. I may try 5w20 again as it seems no matter what type/brand oil I use it eats it anyway.

Did you try synthetic?

Does your coolant disappear as well?

Forget the 5w-20, it'll suck that out like like a five cemnt soda pop. You need to do a cylinder leakdown test & see if the rings are holding compression. If they are it's then likely you've either got bad valve stem seals, or some bad valve guides.

I've just taken the jeep into the dealership (toyota) and they said they cannot do anything for me. Im being sent to the chrysler dealership right next door for testing. Im under a powertrain warranty which toyota will be paying for so I hope that chrysler will cut the BS and just give me a new motor. Wish me luck

So here's the news:

Chrysler dealership did diagnostic work and decided the motor needs to be pulled for internal work.
The dealership from which I purchased the vehicle(Toyota), does not want to pay for said work. They will attempt to contact the PO (a friend of the dealership's owner) and see if he ever made a complaint to Jeep under warranty. If so, they will try to force Jeep into paying for the motor work.
If that does not work, I have the option of letting them buyback the vehicle and take a trade of equal value.

Sadly, they are a Toyota/GM/Buick dealership so my options are few as far as replacement vehicles. It seems as though my Jeep life will be short lived.

Will you break even in the buy-back?

Yes, it will be whatever the purchasing costs were for myself.

I say new engine, or get your money back and go somewhere else and buy a Jeep.

Be polite but firm. You paid for a Jeep in good running order. That is what you should get. If I buy a beer and it's flat, I don't want a glass of milk, I want a glass of nice cold crisp beer!

I have never found leeks on engines either. As far as that goes - No onions, garlic or kurrat either....

But seriously - sure hope you get some relief from the dealer though.

The wagon should, of course, be as light as possible, but strength should not be sacrificed to lightness, for on any but the regularly traveled roads, the wagon will get many a hard knock...
