Default Will an 03 TN1 engine work in a 06 TN1 van?

Hi, I am wanting to know if an 03 engine will work in an 06 sprinter.


TIA

Not likely. The engine controls and emissions are different.

Most of the accessories and intake manifold will need be swapped for the 04+ versions, this includes the turbo. The entire fuel system including injectors will need to be the OM647 versions. The core engine is interchangeable from my understanding.

That is my understanding.

The basic engine is the same.

You cannot swap a removed 2003 OM612 engine complete into a 2006 to replace a OM647 engine.

If you have all the parts from the OM647 engine then the parts should be able to be swapped over to the stripped OM612 engine.

I have not done such a swap.

One caveat may be that all of the threaded bosses or attachment points may not be there for every OM647 component.

Added:
There may be an issue with the mechanical fuel pump assembly on the OM612.

Yes it's possible and has been done before. You use 03 long block with 03 injectors because the pistons are different in 04+. I have done this before let me know if you need more info.

If not too much trouble to answer, for future reference.

I assume the OM612 injectors can be triggered/controlled by the OM647 ECM. Are the injector connectors the same? Does the OM612 fuel rail and solenoid remain?

Does the OM612 low pressure mechanical fuel pump get left unused in place, or is a block plate of some sort used?

Does the OM612 high pressure fuel pump remain in use? (I was thinking that the OM647 high pressure pump had a electrical connection not found on the older style OM612.)

Any other issues you care to share?

Thanks in advance.

Yes the injector connectors are the same and are triggered by OM647 ECU with no issues.
Complete fuel rail from OM647 is also transferred over. You change the front plate where the low pressure pump mounts with one from OM647. Also OM647 high pressure pump is used and it does mount up like its suppose to. In simple terms you strip OM612 to block and head leaving injectors in and dress it up with OM647 components wiring,turbo,rail,pump etc. Everything functions like it should with no warning lights and limp modes (I use DRB3 for all diag on T1n). I have driven swaps like these cross country with no issues.

Great input!!

Thanks for the information. It should be very valuable for forum members as the T1N's age out.

So safe to assume that it works the other way too?

And vise versa for OM612 to OM647.

Thanks again.

Do your research before going too far.

Some input from Doktor A.

The complication you have is mounting and driving the mechanical feed pump and the 612 high pump.

The 647 intake cam lacks the drive extension for the 612 feed pump and the 647 upper chain ramp plate lacks the opening and threaded mounting holes for the feed pump.

The 647 cylinder heads' bolt pattern for the high pump will not allow mounting of your 612 high pump.

And comments by Dennis Lindenengineering that the lower end is ok.
