The turbo'ed versions blew head gaskets constantly. The non-turbo versions were fairly reliable and got excellent fuel economy but had no power. Rated around 165 H.P. if I remember right. They used a unit injection system similar to the 2 strokes. Very difficult to tune and required a lot of special tools to do so. Parts are getting tough to find, don't bother Detroit Diesel for help. Rebuildable cores pretty much gone too. On the bright side 1990 was the last year they were made, and the later versions were supposed to be better. I think they had a standard SAE bell housing but I don't remember if it was a #1 or #2 (just looked, someone on the internet says #2). Not the same as a gas engine.
