Bulletproofjk my oil consumption test started with an oil change done by the dealer and a return check of the level ever 500 miles 1st check it was down 1 1/2 quarts... guess I failed the test!

Went to the dealership this morning after getting off duty to get my loaner vehicle, the JK was sitting there hood open, engine disassembled waiting on the extended warranty adjuster to show up and approve the repair since it will be over $1000 dollars. Just wondering if this will happen again in another 28,000 miles? Took a few Pics of what it looks like if some can tell me how to get them on here I'll post them

They wanted 100 bucks to install it, but I opted to do it myself for 10. I installed it that evening, following a write up on here, and I noticed when the old valve popped out, it still rattled inside, which made me think it wasn't broken in the first place.
Anyway, I took it in today and when they told me it was only using 1/2qt, they also said I still needed a new pcv valve. I told them it was brand new, and that I installed it myself the same day they told me about it. So then, after about another hour, they said the tech claimed it wasn't fully seated.
I'm pissed now because I feel like with their excuses they took away my ammunition for complaining to chrysler corporate. This oil consumption test accomplished absolutely nothing. Even if I complain to chrysler, I'm just going to have to do another test, where they'll have another bullshit excuse. I change my oil myself and it uses well over 1/2qt per 1000. I measure it out every time...I just don't know how the hell to prove that to them.

The second character in the engine number represents the manufacturing plant.

S = Saltillo
T = Trenton

Check your engines. Maybe we can see if the plant location has anything to do with engine failures.
