I bought this running 2.2 diesel engine a couple of weeks ago and just got to cleaning on it and found this plate looks like a patch to me, wondering if anyone has seen this before? I believe the engine is out of a 81 or 82 pup

I have never seen a plate like that on any of several C223 engines.

Unfortunately that looks like a repair plate to seal off a crack in the block perhaps from insufficient antifreeze. Looks like they have a few tack welds in the corners too.

Yes I have seen it done on a good number of engines. Some hold well while others are nothing but trouble.

Aside from the patch how does the engine run?

I removed the freeze plug by it and found that it's not in the cooling system, when I bought the engine it was sitting on the ground and only ran it for a few seconds. When I get a chance I'm going to remove the oil pan and take a look.

Then I hope it was not a piston failure that allowed the top end of the rod to crack the block. Yes you'll want to get eyes on the inside of that crankcase to vet it all out before putting any more time, money or effort into it.

Hopefully you'll find everything inside more professionally taken care of then a metal plate with what looks on the surface to be self drilling hex head screws holding it in place.
