No signs or symptoms? just smoke

Hey guys,
I have done as much research as possible on this matter up to this point as I can.

Got "white" fuel smoke. Its not the cooler or injectors. Only occurs when warm most commonly at stop lights or signs. It will blow pillows of fuel smoke while idling perfect with quick throttle response, no lag. Turbo spools just right.

As soon as you break the throttle the smoke stops. No smoke while under acceleration.

Cold starts are great, no smoke, no even on excessive idle.

No CEL, loss of coolant or any other effects. This started once a month now its 4 days a week. Not an everyday occurrence!

Only thing I changed was running Delo LE 15/40 this time.

I gotta check the FICM output. Do you think it might be the common vane on the turbo, sticking?


A brief introduction:

38 new parts from Ford, cab off approx 1 1/2 years ago. 62k to date.
Coolant filter
All the updates including turbo drain tube and blue file spring.
New egr cooler and oil cooler.
Banks high ram intercooler
4" straight pipe.
CCV Mod
Stock tune
New batteries
Racor fuel filter

You guys are great! Thanks in advance!

Jake

possible that the unisom ring is sticking, when my unisom ring was frozen to the turbo housing with soot it would smoke white at full throttle then the smoke would turn from white to black. It only happened during full acceleration not at idle or a slow roll.

sounds to me like oil leaking into the turbine housing from a bad shaft seal but that is just an off the top of my head guess for a concern like that with no drivability issues.

The CCV mod is blowing smoke as usual. That's a great thought ! Km thinking the turbo as well.
When you drive it hard and roll to a stop it will most likely smoke. When you touch the throttle it vanishes?

Thank you gents

Sounds like a case of blow by or a plugged/kinked CCV mod line. Mine did that when it melted to the manifold.
