Why does my 3126 start up with smoke?

Cat runs fine after a warmup. Power seems normal. Smoke on start up with the 3126 could be an intake manifold heater that is not working. Pretty easy to check the heater for power when ignition is turned on and check it for resistance to make sure it is not an open circuit.

Why does my diesel engine have blue smoke?

Blue engine smoke is the rarest type of smoke emanating from a diesel engine. The presence of blue smoke is an indication of burning oil.

What causes blue smoke from the crankcase breather?

Worn piston rings and/or cylinder walls can be the cause of blue smoke and can cause a loss of compression. This condition can cause more than the normal amount of fumes (blow-by) coming from the crankcase breather. The 8T2700 Indicator Group is used to check the amount of blow-by.
