Look at the clear coolant tank under the hood. If its low, theres a problem. If its not low, ur ok.

If you are making short trips condensation created by the hot exhaust doesn't have a chance to burn off.

I think you may have figured it out..... is the liquid supposed to be up to the cold fill line? Not sure if these pictures help:

I remember they said before they changed the turbo that they bore scoped everything. It all looked great except for the oil that was inside. The turbo going bad was a reason for that. They cleaned it all and changed it. Haven't had the check engine since the turbo..... so I'm wondering if this is a new problem or was related to that problem. If someone can make it sound "related" to the initial turbo problem, they will still cover this problem.

Coolent temps looked fine.

Well the dealer had it for 3 days and then couldn’t figure it out. Today they decided to let it sit and idle for a while....... after 15 min he said he finally got WHITE SMOKE...... (it was 88 degrees today, so not cold condensation.

They are baffled, and don’t think it’s piston heads etc as he drove it for 90 miles with no smoke until idle. They are thinking maybe replace the other turbo as they’ve already replaced the first one.

Any other ideas?

leaking head gasket?
It's hard to see from the pics, but is the coolant level low, and dropping?

K9cop

Waiting to hear back about that. It is low but it was that low (I believe) from the day I got it.
Dealer is convinced it’s not the head gaskets since they only do it after a long idle. No other time. At least I think that’s what they were telling me. Lol.

Going from my 2009 5.4liter V8 to the 2016 3.5 turbo, I noticed that the new truck had a significantly greater amount of exhaust steam/smoke. I drilled the drain hole in the CAC shortly after getting it and the steam/smoke is not happening anymore. I suspect that any condensation in the intercooler is being evaporated by the warm air flow and being pushed out as steam un startup and probably WOT. Unless it's blue or smells, I wouldn't worry about it. Or drill the CAC and see.

The dealer should have a tool for checking if the heads/head gaskets are cracked/leaking, it's really simple using a unique fluid that turns from blue to green when combustion gasses enter the cooling system. More commonly known as a "block tester"

"after 15 min he said he finally got WHITE SMOKE...... (it was 88 degrees today, so not cold condensation."

I don't think there should be any condensation at 88 degree temps.

Im thinking a different Ford service center should take a look at it. There should be no reason they can't diagnose the problem fairly quickly.

Im no EB expert but, my gut and knowledge tells me its a head gasket or a coolant leak in or around one of the turbos. I don't know a lot about how and where the coolant lines are routed through the engine and turbos tho.

just my 2 cent opinion.
