which chevy motor was the good one? wasnt one a converted 350 gas motor?michiganfarmer said:I was a diesel mechanic years ago. Any mechanically injected engine will burn any liquid that will burn. Used engine oil, used tranny fluid, all kinds of veggy oil, anything.
the chevy 6.2, and 6.5.
the ford 6.9,
A mechanically injected engine is anything that has an injector pump with high pressure steel lines going to nozzels that are screwed into the head.
injectors are controled with electricity.
Nozzels are controled with fuel pressure.
nozzels are much more forgiving, and mechanically injected systems have gear pumps that feed the injection pumps with 40 psi, or so. They are much more forgiving. They will pump much thicker fluids, and by the time the fluid gets to the nozzel it has been heated, and thinned enough to atomize.
The GM diesel that was most popular was the 6.5L which came in turbo and non turbo versions. The earliest ones were also non electronic controlled which is a benefit for older truck owners. They were all mechanically injected, just electronically(computer for lack of a good word)controlled. The 6.2L was the earlier ones and I have seen them go 300k mi. with no problem, just lacking in power like the 6.9L Fords. They can be retrofitted with a Banks turbo and will have plenty of power. The Dodge diesels were mechanically injected and also electronically controlled, not sure if any were totally mechanical or what years.4animals said:which chevy motor was the good one? wasnt one a converted 350 gas motor?
