Engine Swap Question - Sprinter to E-Class
I have two dead 2007 E-320's with the 642 engine and one good engine from 2013 642 from a Sprinter. Just wondering when i do the swap if the heads have to be changed and what else would need to be changed. All I know so far is that the block and the cranks are the same. Just really want to know if the sprinter engine is a worth while donor engine for the E320?

The drivers side head is different because the E class takes it's EGR coolant from the back of the head, sprinter does not. Also depending on model tear the timing windows for the cam sensor is different. Oil pan and oil pickup tube are also very different. Pretty much everything that bolts onto the outside of the long block is completely different.

From top of my head
- different intercooler piping
-different motor mounts
-different tune. When car's OM642 are 205-250 HP rated, those in Sprinters are tuned to 188 HP.
-not sure if injectors are the same
-Sprinter oil pan has 16l capacity and will stick under sedan.
Meaning even if you succeed with mechanical transfer, you better reuse all modules from old engine and pray it will work.

Wonder if blocks are similar, as in short block one to the other works. Obviously all the other stuff will be changed. Depends on how MB does stuff with there blocks. As far as sensors go ya can always extend the cables to facilitate if space is adequate.

Blocks are the same, even the head differences are minor if you stick to the same year. I have a R320 CDI long block in my sprinter.

Thankyou for your information. I have the old engine from the car so I would use the car heads ( and cams) and injectors. I would change the oil pans and the mounts from the old car engine to the engine removed from the sprinter. The car ECU and key , etc would stay the same.
Intercooler piping stays with the car and goes to the engine removed from the sprinter.
I hope thats it.

I don't know the age, mileage or condition of your used Sprinter engine at your plan to put in. Having gone through the process, the amount of work of swapping over the short block is not much more than also replacing the piston rings and a connecting rod bearings. That's what I did. I didn't even bother unbolting the mains.

Yes, That would be the best option for sure. then you know what you have. Unfortunatley my old engine is the car ran out of oil and siezed!! This is the way i bought the car. So I'm afraid all the cylinders and mains would be toast. Even the cams etc wouldn't be usefull. I suppose i could strip it and see? I"m in no hurry to start this project so I really appreciate hearing what you all have to say. thankyou so much for posting to this thread.
GL, if ya got time thats the best.

Time is on my side. I'll just put the project on hold until i find a good donor engine. The other option I'm now considering is to buy another 07-09 EClass 320 that is smashed and use the good parts from my two cars to fix the body on a smashed one.
