Story I got with the pictures is, a guy was riding on the autobahn at about 6000 rpm. After hearing the noise (valve seat came loose) slowed and got onto the shoulder and limped it to the next exit.

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

Take your new engine, put a set of new rings,,,maybe a timing chain - and ride. Use the old block for a door stop.
That's not the OP's engine.
And guessing by how long that engine must have run (on one cylinder) with pieces of broken off valve in there, nothing's seized at all.
If it had been shut down the moment it lost power and started making noise, it might even have been salvagable.

Which was what caused 90 percent of the damage.

Exactly, it should have been shut off at the first hint of noise and opened up for evaluation.
