white smoke when tuned

[Powerstroke W/smoke]

hey guys. got a new motor from ford not too long ago after mine died at 18k miles. but recently when my sct is active on my truck, at stop lights or when parked it tends to start smoking thick white smoke. and it does it only when my sct has tunes in the truck. no overheating, not coolant spraying out, no other issues. any help is appreciated guys

Not positive but sounds like an EGR problem to me

have you smelled the smoke? Since it only does it tuned I wouldn't expect it to be an egr cooler leaking. But if it's thick and musty and smells like coolant......well there ya go. How many miles have you put on the new motor?

White smoke can be a sign of a several things. If it does it once its warm (white can be seen in cooler temps before cylinder temps get warm) then its likely a coolant issue, defective injector (think D-max as they are known for this), incorrect injection timing or low cylinder compression (leaky valves, ring issue or coked-up cylinders due to wet stacking...too much cool idling).

One simple test for EGR issues is to idle the truck; if/when it starts smoking then loosen the coolant/degas bottle cap. If the smoke goes away its likely EGR or possibly a head gasket issue.

Good luck man.

why would it go away when the cap would loosened or removed?

I know what yer feeling W/SMOKE!! I've had the same issues over 4 months. Started having issues after running hot tunes for extended periods. No Puking! No Overheating!
Returned to stock..... Ford re-flashed and changed PFE. Pressure feedback exhaust switch.
Part# 5C3Z*9J460*B Sensor Asy.
Smoke free for three days and the cloud returned. Recently had head gaskets replaced with studs and no smoke for a couple weeks. EGR is bypassed! Starting To Smoke Again and still stock tunes. Ya think these rigs are having faulty PFE Switches!!
Too many will same smoke issues!! WHATZUP

Has to do w/ the system being pressurized and if it is smoking while idling and you alleviate pressure at the cap it has an easier route for escape. Not foolproof but a good indication of a compromised egr or h/g.
