Think your engine may need a rebuild? Take a look at these common problems that it might be time to rebuild your diesel engine.
POWER LOSS
Loss of power can be caused by fuel problems, especially severe fuel contamination, excess buildup, injector issues, faulty turbo, or air getting into the system.
POOR FUEL ECONOMY
Too heavy of loads or hard acceleration might cause a drop in fuel economy. It also might mean your diesel engine needs rebuilding. Your fuel might be contaminated, you could have filter or injector issues, or you might have a leak in your system.
EXCESSIVE OIL CONSUMPTION
If you notice your engine using more oil than normal, you might want to investigate the issue before it causes a major system failure. You could be leaking or burning oil, which could be caused by dirty oil, too much oil in the crankcase, high engine vacuum, too little end clearance of piston rings, worn or broken piston rings, oil pressure too high, lugging engine, or restricted air intake.
KNOCKING
Engine knocking can indicate a very serious problem in your engine and should not be ignored. Some causes of engine knocking can include compression issues, faulty fuel injectors, timing issues, failed bearings, or failed wrist pin bushing or wrist pin.
COMPRESSION ISSUES
A lack of compression is one of the biggest indicators of an issue within your engine that needs to be addressed. Compression issues can reveal leaking/broken valves, leaking/broken piston rings, blown head gasket, camshaft issues, broken timing belt, or a hole in the piston or cylinder.
SMOKING
Excessive smoke coming from your exhaust can also clue you in to a larger issue in your engine, especially blue or black smoke. This can indicate quite a few problems, including faulty injectors, faulty injector pump, bad air filter, bad turbo, carbon build-up, poor or incomplete combustion, worn valve guides or seals, or wear in power assemblies.
