Most likely scenario is a flooded cylinder and a hydra-lock condition. If that is the case, make sure you find out what cylinder it is so that you can check it for a bent rod too.

sounds like maybe it is time to pull injectors to relieve all cylinders of any possible back-pressure and boroscope it to ensure there is no damage and go from there.

honestly if its a detroit it locked up on the mains. ive seen this happen 3 times all when idling and its due to oil pump pressure fluctuations from shitty pickup tube orings. they are extremely fussy with bottom end clearance and oil films.

i would pull mains one by one and try turning it over after you pull each one. DO NOT PULL THEM ALL AT ONCE UNLESS YOU LIKE THE TASTE OF CRANKSHAFT!!!

i did change the oil pressure pick up tube o rings few mns ago, you are right they were bad would kick the low oil light when coming to a stop, o rings fixed that

If it's the bearings you should be able to tell by looking at each journal you will see the bad bearing peeling. I have found that if a motor runs out of oil or ran low pressure that the rod bearings lock up first because they do alot more moving around than the mains. I have seen 3 engines ran dry on oil. All three times it was the rods that had them locked. I am not saying it didn't damage the mains but the rod is what locked the motor up tight. Also that the rods are the last to get oil on the crank.
