Cummins white smoke and popping

This is somewhat normal. Same goes for when asking for much power when the engine is cold. Does Size Really Matter? By popping I mean pressure waves of some kind.

When it does this, there is NO visible smoke. At low RPM, everything seems normal, other than a little white smoke , the Bmight be a contributor here. Need some help with an Cummins 6. The truck was tuned months ago and had been running with no problems until about a week ago.

L Cummins engine, and I am having some problems. Sometimes when it is col the truck sputters and blows white smoke , and it takes a few minutes to clear out. It seems we get a lot of questions about white smoke from a deleted truck. Old school diesel guys know white smoke is quite common when the engine is cold.

White smoke is just unburned or poorly combusted diesel fuel. Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up. In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time.

I have a pair of 4bta-2motors in 28. My next door neighbor recently bought a used SeaRay with twin 8. Temp, EGT, Boost is fine. A brand new diesel engine running at full load will experience a little bit of blow-by upon startup.
