Wow, this is a scary thread (haven't checked into these forums in a while).
RDinNHandAZ, I'm a diesel owner. You obviously have enough experience for me to ask the following question, that would otherwise call for way too much speculation:
Based on the suggestion in your last post in this thread about dwest's and others' engine issues post 100k miles possibly being different than what diesel PM owners might expect, do you think that the engine parts that seem to be failing are a stronger or better built version in the diesels or [and this is going to reveal a bit of my own ignorance about all of the differences between gas and diesel engines] is it that some of those parts don't exist in the diesels, or both?
Or, is it that the differences in the low RPM torque of the diesels would possibly allow the same parts to last longer in the diesels -- e.g., rocker arm (roller) bearings in a gasser spinning at an average of 3,300 RPMs would last 120k miles, would be equivalent to 180k miles in a diesel spinning an average of 2,200 RPMs, or something like that?
So, is the difference stronger parts in a diesel or same parts, same number of operations for life expectancy for parts to fail, but more miles because of lower engine RPMs?
Kind of a nerdy way to ask it, just trying to get some expectations for my own PM which, by the way, I bought with an extended warranty for 7 yrs or (I think, but after reading this thread really need to check) 120,000 miles.
Finally, how hard would it be for gasser owners to get FCA to replace (or at least do an inspection of) the rocker arm bearings at or before 100k miles, based on the mounting history of issues (and a reference to the cases posted in these and any other PM forums)?
