2010 unlimited Rubicon. 26000 km on jeep, 3000 km on new motor. Massive oil consumption when the old motor was pulled. Was told by service manager that jeep is using a new part number on the replacment motor and in his 25 years as a jeep guy a new part number means jeep fixed an issue. None the less I love my pile of junk jk, I'd buy it again.

my 2010 SIlver JK with 4100 miles is showing signs of having water in the oil... made an appointment for service so we shall see if its real or just my imagination...
but my coolant level is showing low.. my oil level high and a nice swirly foamy hot chocolate look to the oil... usu == bad news..
my previous 2 JK's never had any engine mechanical issues

I do know (as posted here on this forum) that several JK owners who have either had spun bearings (due to the sump running dry) or high oil consumption have found, upon their motors being pulled down for investigation, that both compression rings and oil expander rings on the pistons had been installed incorrectly at the Mexican engine plant (compression rings with all the gaps lined up, & oil rings intalled upside down). I suspect that that these incorrectly assembled motors were limited to a few batches before quality control identified the problem and fired Gonzales the line worker for being smashed on tequila during his shift (a reasonable scenario considering relevations that workers at their US plant were getting drunk and stoned on their lunch breaks).
The fact that Chrysler covered the cost or half the cost of re-build/replacement of these motors even when out of warranty (according to the people who posted their experiences here) suggests that Chrysler is well aware of the problem. Hopefully this means that they have already dealt with the issues at the plant, so that motors rolling of the assembly line now should at least have their pistons assembled correctly.
Certainly anyone with a spun bearing or extremely high oil usage should have the motors pulled down and all findings documented, even if they have to pay for it themselves. The evidence of incorrect component assembly can then be used in evidence; I'm sure Chrysler would come to the party quick smart when faced with this if they are not being co-operative.
Having said all that, I agree with others that the spun bearing issue is not, based on percentages, a common problem. In comparasin, an example of a statistically common problem with JKs would be steering clunk due to faulty steering boxes/intermediate shafts, which it seems a large percentage of owners (myself included) have or the issue of overheating automatic transmissions.

symptoms point to oil issue and possibly spun bearing.
