That is the funny thing about this failure, it was failing at idle. Very little heat build up. High RPM I had tons of oil flowing. Funny I never heard any knocking either.

It seized up without any heat showing in the bearings? Are there any metal deposits on the crankshaft?

These are the bearings that seized the engine. I have placed them how I found them in the rod. The rod did not have much bluing but as you can see the bearings spun. I have already replace the oil cooler, oil lines and am in the process of cleaning out the cases. I have procured another crank and rods, bearings, chains, oil pump. I am personally bringing this country out of the recession. :D

Hello just wondering if there were any updates to the forensics done to determine cause of the bearing damage?

I am not sure if it was mods I made to the crank or bad rod bearings. See the postings on the Glyco bearings for the 2.4 rod bearings. Either way the new engine will have a 2.0 crank and no mods.
