Granted, any engine can develop crank walk, and doubtless some other Mitsu engines have, but the notoriously prevalent issue affected that particular engine built at the US DSM factory.
Yeah, I know it was directly in relation to DSM engines (but not limited to). That's why guys get confused about 1G/2G - Gen 1/Gen 2 references. It would be more accurate to use 6 bolt/7 bolt references but 7 bolt cranks weren't in the equation on US market Mitsubishi trucks. As far as I can figure out, the Mitsubishi 4G6X engines don't just 'crank walk' and fail - the crank walk is the result of excessive thrust bearing wear which is a symptom of another problem (random oil pressure drops). It could be from crap maintenance, mixing mineral and synthetic oils without flushing between oil type changes, debris and junk jamming oil squirters open - the 'crank walk' isn't a predetermined design flaw.
