Hi Last week My car engine light came on, I towed my vehicle to dealer and he told me drain plug is missing and no oil in engine becasue of which engine seized, I went back and spoke to NTB where I got my oil change doen about 4 month back and they filed a case with insurance and insuarcne denied my claim stating the reason for engine failure is
"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"
But Toyota states
this " Found Drain plug missing and oil residue all the way to the rear, car must have been at highway speed when plug came out, after getting approved to tear down found bearing failure on #3 from lack of oil, also found cams and journals scared when adjuster got here we pulled car in and raised it and oil was still dripping from rear rear struts evidence that it lost oil at highway speed due to drain plug coming out. ".

Please let me know can a drain plug come out after 4 months and can a # 3 bearing fail on its own with 39000 miles and I have maintained my engine very well and have done all oil change on time.
Do you

Hi Bharatjain01, Welcome to 2carpros and TY for the donation

I'm not convinced by NTB conclusion to the insurance people. If you have all the documentation to indicate scheduled maintenance are being kept up its unlikely that it'll have one bearing failure for the low mileage. My theory on this they must have used an impact wrench on the drain plug stripping it and the crankcase pressure help it out while in high speed. This is my conclusion

Hi rasmataz,
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?

Honestly where you stand at this point is the burden of proof is yours to prove how the engine lose its oil. You have meet the scheduled maintenance on engine lubrication and documented-The question here now is how did that drain plug came lose-was it tightened properly? No evidence on the oil pan threads being stripped or the plug-I'm terribly sorry this is as far I can assist you in this matter.
