Well if it spun a bearing it could ruin the rods to keep running it. Or it could sieze again and put a rod through the block...
been there done that.
really messy... sucks the big one.

but, i am 100% for positive it has no bottom end problems, or oil pressure problems.
~40 psi @ idle while hot is pretty friggen good if you ask me. bottom end problems would not allow that.
and ive been driving it since it happened, if the rod bearings were going tits up, they would have by now.
and if it grenades, well, ive got some good pics for you guys, and i still have my old 1.5 turbo engine kicking around..

think its possible that it seized from having improper oil in the crank case?
i did have almost a quart of 20w50 in there.. and it wasnt diesel rated 20w50 either..

I dont think the motor oil would have been your problem. If you were running 100mph, at 25 psi, you were revving what... close to 4krpm?
maybe you touched a valve. timing tooth jumped, or timing belt is missing a cog/old/loose.? or cam slipped. then you shut it down hot, turbo still spinning while no oil goes to it, while everything else cools at different times. maybe the cyl walls cooled before the pistons and rings, which caused them to stick and possibly distort, still giving you some compression but not what you had. then as everytihng was cool, the starter broke free the stuck or burned or distorted rings/pistons. it still goes, but you now have some blow by, as long as the oil is thick, it will boost the compression a bit, enough to keep running, untill something lets go, piston, rod, valve, or possability even the turbo. or the timing belt. ... maybe water in the fuel, or a clogged fuel filter.

the pistons grew too large and stuck to the bores.. thats the only plausible thing to happen. if timing jumped at all, it would have broken stuff. i would have been rebuilding it for sure..
it didnt just lock up.. it slowly lost power. over about 2 seconds, then i threw the clutch in.
it didnt make any noises either..
i was full throttle for atleast a solid minute.. the pistons expanded too much. scuffed a couple on the cylinder walls, and now the rings have been scraping the aluminum off the bores, causing the engine to run better every day..
i know for 100% positive my timing is still dead nuts..

Or the oil broke down too much under the heat and loads and the pistons began to weld fast.. Or a combo of both..
Same but different situation my 2 cycle golf cart was doing the same thing when all this darned ethanol "enriched" gas hit the pumps.. Not to mention I *might* use it a bit harder than it was intended for.. Once warmed up and run hard it would loose power, when shut off it would be locked up.. ABout an hour later it would start and run, just not so well..Specs for piston to bore clearance is rather large so I don't think it was expansion as much as the lack of lube.. Upping the oil in the fuel mix and a cold air intake straightened it out..
If it isn't knocking (in ways other than it should) run it... Heck I'm still sucking oil out of my overflow tank and yet it keeps going...

made a trip to portland and back last night.. (250 mile round trip + some running around)
and my car never skipped a beat, except when it started leaking on the fuse box and my foot.
no knocks out of the ordinary, didnt get abnormally hot, besides the fact my rad fan switch is dead..
