Hello.

So somebody told me that the OM615 and OM617 are so similar that they are basically interchangeable. So if you have say a car running a OM615, a OM617 will fit on the same mounts, fit on the same transmission and fit the 615 flywheel to use your old clutch or torque converter etc, because the 617 is basically the same casting but with one extra cylinder. But the bell housing bolt pattern, the engine mount locations and the flywheel bolt pattern are the same.

So to convert from 615 to 617 you just need to mess with plumbing and pipes and exhaust and such.

Anybody know how true this is? I have a 615 but don't have a 617 I can compare it to.
