My fuzzy memory is that the Motori V6 diesel was first used as a boat motor and was reliable.

Roger Penske, no slouch at diesel science, owned controlling interest in Motori at one point.

I wonder if some Italian trade magazine ever wrote an article sorta like: Everything ya ought to know about using and rebuilding the Motori V6 diesel?

Even the Cummins I6 hit the skids for a few years when the EPA convinced Cummins to go with the EPA’s extreme EGR NOx “solution” rather than DEF injection.
