First and cheapest, always check the air filter or for air restrictions.
Black smoke- overfueling. restricted air flow, injector nozzels not closing completely.
White smoke- water
burning in cylinder. low compression
(valve adj. or burnt valves)
( if low comp, smoke will burn your eyes from sulfer smell ) cold diesel engine
will always blow white smoke til engine
warms and pistons expand.
Blue smoke- burning oil
after checking air filter, try accelerating slower from dead stop to cruising rpm
. if still have problem, send injectors out and rebuilt and tune the engine.
Hope this will give direction, from cheapest to most expensive.
