white smoke issue????

Ok, 2000 f250 with new rebuilt 7.3 with perfect compression numbers. I have rebuilt injectors with stage 2 nozzels, oil has been changed since rebuilt engine. I I am getting a pretty good amount of smoke coming with normal acceleration from a stop. Truck starts and runs like new with perfect compression and no blowby. Just really smokey...... I have lil over 2k on engine since rebuilt and has done this since rebuilt was put in, just thought it was my injector making this happen. also truck has no smoke on cold starts since rebuilt engine and has been in the mid 30s here last couple of weeks. Truck fires right up runs perfect with no romps or anything like that with older injectors on cold starts.

any clues or hints please.....

Even after the compression numbers turned out the way they were, that wasn't the cause of the smoke? Rough deal for sure.

How about air in the fuel? Air leaking into the fuel bowl? Fuel pump pushing low PSI causing a mini vapor lock?

Have you had the dealer check HPOP pressure and fuel pressure?

I hope you get this figured out.....mine is doing the same thing!!!! Doesn't smoke until it warms up.Was doing this when I bought it and I thought it was the SCT tuner. Got a chip and it's a little better but is pretty bad around town stop and go.Smoke is light gray to white.

Do you still have the crank case vent tied into the intake? Iím thinking PCV (vent) or turbo putting oil in the intake, ether way have a look see in the intake lines for oil wetting. Next guess would be a valve guide seal which you would need to pull the manifolds to find.

I hope I can figure it out too. Getting tired of seeing smoke in the mirror and I am sure the people behind me will too. Same here, light gray to white but no coolant smell at all, straight diesel smell.
