I just picked up an 84 k5 with a 6.2 and a turbo. I see no labels identifying it, and am lost. Ok im an idiot so far on turbos. It sounds a lot more like a gas engine than either of my other diesels, I suppose the single exhaust. Anyways, there's no boost. No smoking, runs fine, just... Almost exact same power as my 82 and less than my 89. The manifold pressure gauge has no reading. I can stick pics online, but.... Where do I start? Hep me, hep me, hep me!!!
