Siezed engine... Any hope?

[rocktamer]

So this thread is about a gasser, but I figure the same principles apply.

I have a 2001 F350 V10 work truck. I pulled up to the shop one night last week and parked the work truck. I tinkered with my diesel for a few hours. I went to my work truck and tried to start it and nothing. I could hear the starter engage but not turn. I checked the battery, all was good there. Made sure the starter as getting the proper voltage, good there. I tried to turn the nut on the harmonic balancer, attached to the crank, and could not get it to budge. I took it to a shop and they came up with the same conclusion, the engine is seized.
I dont believe there was any catastrophic failure. The truck was not overheating, i did not hear it throw a rod or anything fail apart in the engine, and everything was normal when I parked it and turned it off. The only concern I have is possibly the oil pump went bad, which might cause this. I am curious what your thoughts are on this.
I am also looking for any plausible way to attempt to get the engine cranking again. Any recommendations would be appreciated and considered.

Never tried this on a truck, but has seen outboards sieze and many times pouring marvel into the cylinders and letting it sit has freed up the motor. Also there is a company (not sure the name) that makes something specifically for this

Someone tell me if I'm wrong, but if it seized, it would have done it while running correct? And if I understand right, the engine was running fine when you shut it off.

You might be better off posting this in the gasser section.

If it's seized from heat then you are going to have to pull all the plugs and fill the motor with Marvel or something else to try and lube the rings, also you may find you need to drop the pan and look for a blued rod or main cap. If you find one loosen the cap and see if the motor turns. If so you had excessive oil starvation. They just don't stop turning for no reason.

Some where I had read ford had oil filters were failing causing engine damage on them

Could the starter gear have gotten jammed in the flywheel? Which would cause your truck not to start and the engine not to turn. I'm not sure how likely this would be but it's just a thought.
