Thanks for your reply, but i am not form mechanical background so could understand you could please elaborate.
here is the complete NTB report.
"The technician removed all the cam caps and there are lightly scored. The camshafts journals are lightly scored. There is no discoloring to the camshaft journals or caps. There is no scoring or discoloring to the camshaft lobs or lifters. The technician removed all the rod caps and the #1, #2 and #4 rod bearings are scored. The #3 rod bearing has spun and is missing. There is no heat discoloring to the rod caps or rod journals of the crankshaft. The #2 and #4 rod bearings are pitted. There is a lot of metal in the oil pan. There is large metal pieces in the oil pick up screen, but the screen is not blocked. The oil pan has a new drain plug installed and is tight. The technician states there is no damage to the oil pan drain plug threads. There is no impact to the oil pan. The oil filter is not new and does not appear to be leaking. The oil filter is a PZ-21, yellow in color. There is no sludge seen. There is oil blow back from the engine to the muffler. The technician states there was no oil or drain plug when the vehicle came in but the inspector can not verify this. No other damage or failures noted at this time
Cause of Failure
There is an isolated failure of the #3 rod bearing with subsequent damage to the engine from metal contamination. There is no heat discoloring to indicate a lack of lube condition. There is no verified failure of the oil pan drain plug at the time of this inspection.
They are denying my claim stating there was no heat discoloration and and it don't take 4 month with 1900 miles driven between the oil change for the drain plug to fell out.
Toyota says if the drain plug was hand tighten then it might take a while for it to come out, and since i didn't drive the vehicle as soon as i saw the engine light, there is not heat discoloration if i would have driven then there should have been heat discoloration.
I have picture which shows oil leakage all the way from front to rear.
Do you think NTB is right or Toyota???? Since NTB is denying my claim i am not sure what to do?
