Hmmm...I'm still not quite buying this. It hydrolocked while RUNNING? How is that possible?
Now, it could have been running like a wet dog and the excessive fuel could have washed the cylinders dry and then seized them. But I can't imagine the engine taking in that much fuel while the piston and valves are working away in there at high speed. It couldn't pump it fast enough.
So this is not a correct diagnosis in my opinion.
Either the cylinders did seize from having no oil on the walls, or the car hydrolocked while being started up, after the fuel actually had time to fill up the cylinders.
I suppose it is possible that you did the damage by a partial hydrolock when you started up, and then drove the car with valves bent, etc. until it gave up. That's seems plausible.
#21 of 43 I'm thinking the same thing...

And if this were the case, think how it would have been running!
Something seems funny here...

stereotypical guesswork from the service advisor...

I'll bet that engine is fried inside, washed clean of lubrication, causing a seizure.
the only way an engine could hydrolock while under full speed would be running through a deep puddle or creek and having a huge amount of liquid sucked into the air intake...we are talking gallons per second here.
#24 of 43 It wasn't raining heavily out, was it?

#25 of 43 what happened when engine failed
Oct 10, 2003 (11:03 am)
the problems started with a bad battery. I was exiting the freeway and the engine died. I started it while still moving but it died again. I stopped and the second time i tried to start it I revved the engine when i cranked it. that's when i heard the bang. I don't know if starting it multiple times caused the cylinder to flood. yea, its possible the engine seized and then flooded. I hope not.

Is not a good thing.

Well then it didn't hydrolock, so that's not what happened.
If excess fuel washed the cylinders clean, then we would find a very high reading on the dipstick.

I was just curious as to whether or not any CEL or oil warning lights came on before the engine blew. Also I would imagine in an upsetting situation like that, it woud be easy to over rev the engine in an attempt to keep it running.
I also question as to how they knew the oil pump was ok in a blown engine.
Also 11 grand for an engine? It must be the gold series engine..as in made out of solid gold.
If you put in another engine, Hope it works out for you.
I must say that I long for the good old carb and ignition points days, as I read more and more horror stories in these forums.
Good luck with what you do.
