What causes diesel mixing with engine oil?
The Causes of Fuel Dilution in Engine Oil This often happens in the region between the piston rings and the cylinder bore. Other factors include leaking of the fuel injectors, incomplete combustion of the fuel, low engine temperatures, long periods of idle time and frequent short-distance driving.
What causes excessive smoke from diesel engine?
Over-fueling is the primary cause of black smoke from the exhaust of a heavy duty diesel engine. Over-fueling can be caused by diesel fuel injector wear that enlarges the nozzle hole or erodes the injector needle and allows excess fuel to flow into the combustion chamber.

Can a bad diesel injector cause blue smoke?
Can faulty injectors cause blue smoke? This can be caused by worn/leaking injectors or restrictions in the air intake system. Blue smoke is normally the result of engine oil entering & burning inside the combustion chamber. This is most often caused by low compression, or worn piston rings.
What causes a diesel engine to blow white smoke?
Diesel Engines Blowing White Smoke from Exhaust 1 Faulty or damaged injectors 2 Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway). 3 Low cylinder compression (eg caused by leaking or broken valves, piston ring sticking, cylinder and/or ring wear, or cylinder glaze)
