Smoke through intake!

after I’m driving and get the truck up to temp whenever I shut it off there’s a little smoke or steam coming through my air filter. What could this be?

"Steam" from oil/combustion gasses.. the crankcase breather vents directly into the intake between the filter and turbo

Yup, also why most trucks end up with a little oil in the CAC tubes and boots.

Unless it's really bad, nothing to get that shook about.

Take the oil fill cap off whilst it's parked and running. If it blows the cap off when you sit it on there upside down then you have more than normal blow by.
