Majority of the time dealerships are not informed of yard holds or anything that may be engineering related or a tightly seeled comercial issue at DCX. All they are, are salesmen and women. If you want to know some facts then try contacting one of the engineers at JTE in Detroit...but there not going to tell you anything

I do however, work for an organization that can and will provide me with the reality of any given situation from the manufacturing side of things. On that note, I have not seen or heard of any oil leak issue and by reviewing the 3.8 tech adaptation, I can't see where one would develop (to the point where production would be halted).
Yeah - there are definitely some good salespeople out there - looks like you're one of them.

I have noticed over the past 10 years or so that salespeople are overall getting a bit less pushy and are generally slightly better informed. I think that is due to the advent of the internet where a potential customer can fairly easily gather a ton of information about the car they are looking to buy - keeps the sales staff on their toes. From what I've seen the manufacturer and dealerships only do so much to educate sales staff. If you really want to get informed you've got to do it on your own, which I 'm sure makes you better at your job and leads to increased sales and return customers.

Thanks again for the info! This is in another thread, but do you happen to have access to power curves for the 3.8 and the 4.0?

I now have 2500 miles on mine, and it was in once for an oil leak. They said it as something with the filter. I have no idea...but it seems to be fixed now.

There should be expected that there are going to be issues with the JK because its in its first year of production.
Exactly what I have been thinking while reading this whole topic. Simply saying that it is proven technology in a mini van means nothing.

Adaptation of the 3.8L engine to Wrangler and Wrangler Unlimited required
the following modifications:
New exhaust manifold due to packaging

Modified intake lower manifold to add bosses for the ignition coil and air
inlet due to packaging

Cylinder block motor mount bosses added as part of impact energy
management strategy with Pre-Loaded Engine Bushings (PLEBs)

Front engine cover modified to accommodate mechanical fan as part of
heavy-duty cooling

Oil filter location moved from side of block to chain case cover

One-piece rear crank seal assembly is molded onto a stamping and
replaces three parts

Two-piece structural oil pan for noise, vibration and harshness (NVH).
Lower portion is steel for impact resistance; upper bolts on and is a
structural tie to the transmission. The upper is made of aluminum

Oil capacity with filter is increased to 6 qt (5.7 L) to meet Jeep
requirements for engine lubrication

mechanical fan? I read this at rockcrawler.com
Perhaps the nicest thing about the new engine on the dusty Rubicon Trail was the new electric fan. You could hear it cycle on and off with a gentle buzz and it never had that high-revving roar the inline six had. Better yet, it also didn't fire a downward blast at higher rpm's. The TJ's fans would cause such a huge cloud of dust from underneath that the Jeeps looked like Peanut's Pigpen going down the trail. You'll be thankful for this, as will anyone behind you.
sounds like electric fan plus the gap from the front of the engine to radiator would rule out a mechanical fan?

Not saying that there is in fact an oil leak issue but, these changes have absolute potential for new oil leaks developing.

NEW 1 pc. rear main seal
NEW 2 pc. oil pan
RELOCATED oil filter

Also , the JKs ive seen have the threaded boss on the water pump snout for mounting a mechanical fan

There is no oil leak. Not a shred of actual evidence.
