I left the house this morning and about a mile away my truck started smoking. It got to the point of being embarrassing.
I pulled into a store to get a coffee figuring I was going to limp back home. When I pulled out it didn't smoke as bad then cleared up, completely.
I smelled the smoke, it was oil (pretty blue) and it was coming out the exhaust.

I pulled out as soon as it started, no warm up.
It was 15 degrees out.

The only thing I can figure is:
The oil pressure was high due to being cold and with that, the restrictions around the turbo bearings (that keep the pressure up before the drain) combined to push some oil out past the seal.

After things warmed up it went back to normal.

If it was a failure it wouldn't have cleared up.

Has anyone had this happen???

Oil is 5W-40 synthetic changed every 7K.
Turbo has about 25K on it.

i wouldn't worry, things don't like 15deg out, esp under pressure as you said. It was pushing some oil by..

 

Those oil change intervals may have had something to do with it...

 

My F350 work truck does the same thing all the time. Its a matter of the turbo seals not being warm enough and letting a little oil into the turbine. Just have to try and stay out of any decent boost until its warmed up enough.

 

X2 that's too long IMO on a natural aspirated vehicle let Alone a forced induction vehicle .

 

I have ran my setup for years in Alaska and never had this happen. Even at -40 below zero. But I have never just started it and started driving it either.

 

How is your oil drain back line plumbed? Pics?

I agree with the others about your maint schedule.

 

****, I change oil when oil light goes on,

 

5K tops, filter changes at 2500 if you stretch it that far...

Always allow sufficient warm up time. Probably just pushed oil past those cold seals.

 

Like I said, hehehe
