High oil temp and pressure sluggish moyor

[Crosscarriers]

Yes it was Summit International in Kansas City Missouri. Like i said it regened 20mi after picking it up and it just regened again about 30mins ago.
Ive only put maybe 2000mi on the truck since picking it up and when i pulled over it was leaking smoke again right after the turbo pretty much right there at the doser valve and nox sensor. Its not smoking as much as it was before we tightened the clamp but definitely still leaking. Could this damage my turbo or doser? And shouldn't this trigger a sensor somewhere? I appreciate all the help!!!
