Lack of power in diesels:
#1, a blown turbo line (Bad Charge Air Cooler, popped off clamp or hose)
#2, a bad turbo, oil will be dripping out of the exhaust tubing.
#3, Restricted air intake, dirty air filter or crushed air piping.
#4, Restricted exhaust, blocked catylitic converter (you unfortuneate soul) or crushed piping or malfunctioning exhaust brake.
#5, Incorrect injector pump timing.
6V92 has a blower instead of turbo I believe and they had a problem with the drive coming apart (engine starts but blower doesnt operate) however, that wouldn't let you out of the driveway. Also, 6V92's, if I recall correctly, operate with the DDEC IV Engine Computer, so if the visual inspections don't reveal anything obvious, I would recommend taking it to a Detroit Dealer (any Freightliner, Peterbilt, Kenworth) with a Detroit sign, will be able to hook up and decode it for you. If you have no computer and the engine has a mechanical fuel pump, take it to the same shops above and don't let anyone without gray hair touch it! Good luck. |
