@bigchevy80 This one was the DX, suposed to be much better than the old D, but I think it's still bad.. I have converted the car to 6,2 Diesel, it gets around the same mpg, it's almost as fast as a 350 gas, It's like a space rocket compared to the 5,7DX, and it's much more reliable....

@kiarra00 The later ones were much better. I had one in an '84 Caprice that had close to 200,000 miles on it and ran like a top. Convert the head bolts to ARP studs and you're good to go.

damn it was smokin

The idea was sound...the fuel shortages of the '70s were still fresh in everyones mind, and GM was trying to get compact MPG from a full size car. sadly this engine was awful, stretching head bolts and blowing HGs for a hobby along with a weak bottom end. I owned a caddy seville with this motor, a lovely car spoilt by the engine

I was a GM mechanic in the early '80's, and we would cringe every time one of those Olds diesels came in on the back of a tow truck- and it seemed like it was every single one made for a time. 9 times out of 10 the engines had to be replaced, with either a new diesel or we converted the car to a gas engine. The 350 diesel engine was overweight, underpowered, and unreliable. Mercedes knew how to build an automotive diesel at the time- but GM did not.

@DaBoogie049 I have put a 6,2 Diesel in the car now, and they have a much more massive sound than the 350 diesel, I have a video of the first startup.
do you still have the engine? if so i am looking for one to rebuild and convert to run on vegtable oil...

@Gibson299 I did put a diesel in it.... 6,2 from Suburban... Roughly the same mpg, much faster (almost as fast as 350gas) And much more reliable than the 350 diesel.. Check out my video of the 6,2 running in this car. :)
