I'd be interested to find out what caused the failure. Unfortunately, it's tough to figure out at times. The Explorer I have, it was easy, several inches of stuff in the oil pan that resembled wheel bearing grease. I got it that way, replaced the rod bearing and cleaned out the pan, and it's running pretty well. My Intrepid that I've had for about 8 years, not so lucky to know the why, but the 2 rod bearings I've had fail, did not spin, did not hurt the crankshaft, and I was able to replace the failing bearings and drive it. The first bearing was over 100k miles ago, the second was about 8-10k ago. The bearings looked like they were peeling, and according to a bearing failure analysis chart, it was surface fracturing. According to the machine shop we use at the shop, it's from the really high cylinder pressures, high operating temperatures, and basically the engine being ran near its design limits, with over 200 HP from 2.7 liters, and enough torque to move a full sized car down the road without feeling like it's slow.
