Blue smoke

[Nasty7.3]

2003 7.3 blowing blue smoke replaced turbo and injectors?

Has a constant haze when driving. Almost nothing at idle

Check CCv for blockage and check blowby. Too much crank case pressure will cause blowby. Blue is oil.

If you havent driven it much yet it could just be left over fuel and oil in the exhaust system from the injector swap.

Has it been a constant problem before injectors & turbo? How long has it been doing the smoking....

Does it have a loss of power. & how does it start cold. Also what's the miles on the engine

I had an issue like this recently. But I had smoke,hard /no cold start and very noticeable loss of power. Ended up being low compression

Yes before injectors and turbo and after motor has 200,000 but has always ran strong and good. Never smoked till one day having some fun doing a burn out ha.

Normal amount of blow by and crack case vent had a little kink in it so we will see
