M156 engine interchangeability
Hi guys,
Curious as to what issues might be encountered swapping out an existing M156 but replacing it with one from a C or ML-chassis into a W211 E-chassis?
Do the various M156 engines have any differences in oil pan? Engine mounts/crossmembers? Harness (just plug'n'play or a headache of a splice job)? Anything else?
M156 E's are very rare here, and to source a donor engine it will almost certainly have to come from a C or ML. Hoping it is a relatively straight-forward approach, however I am bracing myself for it to be anything but.
