Om642 v6 diesel

[Blackducati]

Hi. Does anyone know what the big end and main bearing oil clearance on the OM642 is please? I am rebuilding the engine with new oversized bearings and want to plastiguage them before I install them. Many thanks

Not if it's a small one...(or printed in lots of small pieces)!

Hi. My name is Robert Lewis I’ve been told that you are a bit of an expert on Merc engine’s! I am trying to find out what the big end and main bearing clearance is on the OM642 v6 Diesel engine. I am totally rebuilding it and want to plastiguage it to make sure that it’s all good before final assembly
Kind regards Robert

No problems with diseasal engines as long as all the emissions control equipment is fitted and working as designed...
I wouldn't have one through choice but can see the attraction for some.
