That sucks that he had to pay, but that seems like not a bad price for parts and labor. I assume the dealer didn't do the work? At least the j&p will probably be better then the factory engine.

Fortunately I didn't undergo any terribly expensive corrective actions to resolve the pinging before my engine was replaced at 60,000 miles, under warranty. However, I had replaced the expensive oxygen sensor and an EGR valve around 50,000 miles. I'm sure both were destroyed by sending so much burnt oil exhaust down the pipe, but I had to pay out of pocket for those repairs. I wonder how my catalytic converter has been affected.

There was also a period of time where the lifetime could be purchased for the years you state in various forms. 0 deductible, 500, etc.... I purchased my 07 lemon on 25 July 2007. lol I think I paid 750 for the 0 deductible lifetime. So they got me double with that one.

Yes I had my short block replaced under warranty after a few consumption tests. Now it appears to be running great without any oil loss! Mine was done at around 64k miles. But they did kinda get me, my radiator was cracked and they had to replace that too (not under the lifetime powertrain).

Sad to say my beloved 07 2 door has joined the ranks of oil sucking JK's. It's going in today for diagnosis at the dealership. Haven't even hit 50,000 miles yet.
Between the deep rod knock at startup and needing a full quart of oil about every 200 miles the motor is likley toast.
Motor, intake, exhaust are stock. Changed oil at dealer every 3,000 miles since new. Trans, transfer case, and diff fluids have all been replaced twice.
Bummed. I've taken exceptionally good care of this motor and it's crapping out on me at low mileage. Guess all I can do is wait and see what they say.

Our current racing oriented Jeep also started consuming oil after only 12,000 miles- reason was found on overhaul, as both pistonrings and valve stem seals were completely worn. Engine consumed about 0.5 litres on 100 miles. The premature wear was most likely to be caused by too rich mixture, which flushed the oil from cylinder walls, but the engine had also consumed some sand, water, mud and other stuff, that shouldn't go into engine. next season we are probably going to swap for Pentastar becqause of the weight and power
