1978-81: Chevrolet and GMC C10 Pickup
This is the truck side of the 1978 Olds 350 diesel debacle. That same year it was added as an option for the very lightest-duty half-ton, two-wheel-drive Chevrolet and GMC pickups under the Ordering Code LF9. This engine was less problematic in trucks than in the cars because truck owners were a little more diesel-savvy and didn’t do some of the silly things that got car owners in trouble. Still, the trucks had their trouble and ’78 and ’79 were the worst years. Most of the issues were fixed by 1980 and the engine was available through 1981 in full-size trucks, replaced for ’82 by the all-new 6.2L diesel.
