Default Excessive smoke

I have a 2005 I rebuilt the motor 30,000 miles ago... all stock. The last couple weeks I'm getting a lot of white smoke when I start it up in the morning after its warm no smoke at all......any suggestions?

Possibly a leaky injector. I would send an oil sample in and get an analysis done. Is there any blow by?

Remanned or brand new injectors? Either way i would get an oil analysis done. I think its only $28 at Blackstone.

Retorque your feed tubes and injectors. Run a good dose of injector cleaner through the system encase some gunk is causing an injector to leak.

Also make sure you check for blow by.

That is a sure sign of a bad injector get it fixed before you melt a piston! Worst case is you already melted a piston but since the smoke goes away you might get lucky! Pull them all send them back to who sold them to you for testing! really weird that NEW injectors are doing this?! Remans do it all the time!
