History of the 350 Diesel

Oldsmobile came out with the 5.7 Litre 350 cubic inch Diesel engine in 1978, and was available in almost everything from Chevy Trucks to Cadillac during its production period. They where produced mainly for fuel economy due to the gas shortage in the late 70's early 80's. They were known to be very bad engines as they arrived. Lots of Injector Pump problems, blowing head gaskets, and poor maintenence due to lack of knowledge basically killed them. Many engines were perfesionally changed out by GM mechanics, but still with many top end problems and poor maintenence, and also due to water in the fuel.The first few years of the 350 Diesel were the worst ever, as far as most people are concerned, in some people's opinions, it was the worst engine ever, but it was all due to poor knowledge and lack of maintenence as far as I'm concerned.

All Oldsmobile Diesels were discontinued for the 1986 model year eventhough they were practically perfect by then, therefore most were forgotten, and a wide margin were gone...not everyday do you see a car or truck with a 350 Diesel, but when you do, they are runnig great! The few that chose to put a remanufactured engine in instead of a gas 350 are still driving them with tons of miles on them. I have mine in a 81 Pontiac Bonniville...its a Remanufactured one, but it runs perfect.
If you take care of them, they will last forever!
