Completely normal, at most it needs to be cleaned. If u dont believe me just get it inspected.
Blue smoke is burning oil.
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
Blue smoke is burning oil. If the smoke stops after a moment, It's your valve guide seals.
Blue smoke is caused by engine oil being burnt by the engine.
Hi there,blue smoke on a diesel motor is normally fuel,and the smell will be unburn diesel,rough start and heavy smoke that will disapear as the engine getshot.
blue smoke is pretty bad.. your adding ethanol to your diesel fuel when your at the pumps Blue smoke could be a sign of engine wear. The blue is the engine oil being burnt in the engine. 2 possible wear parts are the intake valve guides and the piston oil rings.
My understanding of exhaust smoke is that Blue is oil, Black is unburnt fuel, White is unburnt diesel on cold start. The main question would be, how much smoke and when does it do it?
White smoke is a coolant leak Black is a rich condition Blue is burnt oil.
Usally that is an indication that the valve seals need replaced.
White smoke means water, blue/black smoke means oil, black smoke can also mean the fuel mixture is too rich.
A diesel puts out Black smoke when it is running Too Rich. Blue means Burning Oil, white is a Coolant leak (Blown head gasket). Black actually means it's wasting Fuel.
"BLUE" smakoe on a diesel can be a little confusing, made worse by what era the engine comes from and if the emisions control stuff in the exshaust has been removed. Old school heavy duty deisel engines for large trucks and rail locomotives, 1902 untill 1980's will put out green blue acrid smelling greasy smoke when cold or allowed to idle to long. Normal. All diesels but out a pull of black or white smoke at start up. Newer Diesel engines will only smoke blue if they have a bad injector or are worn out. For the blue to get through the polution control stuff since about 2008 means there is something really wrong.
