All 3.6L owners should run a few UOAs starting at 50K to check for potassium. My oil cooler started leaking at 50K, but I did not see (or smell) evidence of it until 63K miles which coincided with a spike in potassium which continues to rise.
When I look back at the UOAs, I can see the potassium spike that was small (3PPM) was the start of the leak which only became worse over a short time.
The oil filter housing/cooler design that FCA has is one of the worst I have seen in many years. No o-ring support in the form of a machined boss in the block and plastic construction combined with higher operating temperatures and oil pressure is a perfect recipe for a guaranteed leak.
What a POS...
