Signs of a factory reman diesel engine? (W115)

[mabbonizio]

I have a 72 220D that has had an OM616 dropped into it at some point in its life.

There are some peculiar aspects to it. For comparison, I have a 82 240D with original motor. That car has the engine number clearly stamped on it.

On the 72 here are its oddities:

Some large numbers in white paint stamped on the front of the engine. Cant read em, they've worn down.

Vacuum shut off on the injection pump (gorilla knob is required to glow and start the motor but does NOT shut it off.

Injection pump looks like whats on my 82 240D

Old Loop style glow plugs

Oil filter is at the bottom of the engine like it would be on a W115

Intake manifold looks to be from an early W123. Car has a W123 air cleaner and takes W123 240D air filters.

The reason I bring this up is because I think the throttle linkage is some type of hodge-podge setup and is not achieving full throttle, won't allow the manual engine stop level under the hood to shut down the engine, and has lots of slop so I'd like to replace it all.

thoughts on this being a factory re-man engine? It seems to have excellent compression and starts immediately, runs nice and smooth.

On the front of the engine, my '82 240d has an ID plate with the word 'TAUSCHAGGREGZT'. I was told on one of these forums that it's a factory replacement engine. Don't know if this applies to yours. As my car is 200 miles away at my parent's home right now, I can't verify anything else, like engine-numbers, at this time.

I was at a dealer picking up some parts during the middle 80s. A shipment of factory rebuilt engines was delivered while I was there and I got a chance to look at them.

I noticed that the spot where the engine number was supposed to be was covered up by a tag with the words MERCEDES-BENZ and then that long Tagger word. There was no engine number on the engine, but there was a spot under the tag where I was told the dealer could stamp a number in by hand if they wanted to.

This place would stamp in the original engine number, from the original data card, if they were doing the replacement. Otherwise they sold it without any engine number assigned.

They said they sold about six of them a week.

Six a week? That's not very encouraging!

This was a dealer that got a air container in from Germany every day. They usually had a waiting list for replacement engines.

They didn't really like to stock large items since they could get them overnight.

And they didn't like to sell them to anyone but shops they worked with. You could buy one but you could have yours rebuilt at a shop for about half the price. For the general public there was 'special pricing' which discouraged do-it your-self types.
