240D engine compatibility 616 912 versus 615 912
 

The machine shop that has my 1983 240D engine has an engine that they rebuilt that the owner never came and picked up. The guy that runs the shop says that he will let me have the engine (long block) at a minimum cost (includes cylinder head). I am going down at lunch to discuss it with him. Seems the first six numbers are 615 912 whereas the engine that came out of my car is 616 912 12 086860. I will get the rest of the numbers at lunch. He seemed to think this was an older engine. What all is involved to go to this "older" engine and will my injection pump work on it.
thanks,

Here are the numbers
My engine I am planning on rebuilding:
616 912 12 086860.

Engine that they have already rebuild that is for sale at a very economical price:
615 912 10 074644. What model/year would this be out of?

I went and looked at it and it looks pretty "new" - having never been run since the rebuild. Took a peek inside the oil fill cap and it was spotless. I did notice that it has the "old" style glow plugs. Would this engine work in a '83 240D with a minimum amount of trouble?

I think a 615 912 engine is a 220D, most likely a 71-73.

Your 616 912 engine is a better engine. In addition to the glowplug issue I think the 615 engine has a different oil filter location, no provisions for an A/C mount where your R-4 compressor is located in the 240D. The injection pumps are quite different as well. Your 240D is an automatic and the 615 engine is from a 4-speed so you will have to change the flywheel to the automatic version.

I would shy away from this one, even if you could get the 220D engine for nothing.

Good luck - Tim

Thanks - that is the information I needed. If anyone wants to call the guy it is at Cassidy Automotive Machine shop - Macon, Ga. (478) 746-3296. Ask for Gary. I am proceeding with the rebuild of my '83 engine.
