This was not an engine that GM had Trouble with. You are referring to the car 5.7 engine that many consider to be a gas engine converted to diesel fuel. while that may be true i believe they did beef up the block some along with the heads it was not enough and along with the short pushrods those engines did not reliably last. As to their toughness they were marginal at best. The engine you refer too is basically an industrial type engine that is very long lasting with the proper maintenance. The only real pain in the neck problem I can think of is that some of them (most depending on who you ask) leak oil. Usually a small seep here and there that just gets messy after a while. I dont know if it was the gaskets or what but they get dirty in trucks. They can be noisy but they are a working mans engine. A little detail to the sound deadening system can usually quiet things down acceptably.

One thing about them is if anything (i.e. broken keyway) happens to the positive displacement roots type blower (not the turbos) it will not start or even run. We have had this problem with the engine in our dump truck. In a truck that doesnt bother me, but on the water I'd be nervous. But first, they are LOUD engines with that blower screaming. During my US Navy years they were trying hard to get away from them since there were alot of better applications out there. > > Regards, > Terry Wilhelm > > Jack Kenworthy <[EMAIL PROTECTED]> wrote: > I have a question for any mechanic-types out there - particularly marine-diesel familiars.
