Wrecked engine restore.

I bought two 1985 300D Mercedes one is a parts car, one is the main car. The parts car was parked because it was driven over a ditch that had a log in it and ripped the oil pan off. The previous owner drove the car for about 20 minutes before parking it. Is it possible that the engine is still okay? I've heard how robust these engines are but I don't think even they will last that long without oil...

20 minutes without oil. I would say, unfortunately, the engine is toast.

Is it the proverbial running when parked or it ran for 20 minutes before seizing?

Can you turn the crank by hand?

Define drove... putzing on a slow road versus higher power ops?

The oil pan ripped off, as in zero oil??

Yes and yes. Also the engine wasn't seized when parked as far I know.

If it is not siezed I'd look in the pan and on the oil pump screen for metal pieces. If you don't find anything significant I'd install a pan and try to start it. If it runs and has good oil pressure you might have gotten lucky.
