Oil Residue In Charge Side Of Turbo

Okay so I did a search and read this may be caused by pvc discharge into turbo. I have oil residue in the charge side but it is not wet but rather hard and sticky, very difficult to wipe clean. The other thing is I'm having trouble believing the pvc oil discharge because I had my friend (also LLY owner) pull off his charge side boot at the turbo and there is no oil residue in his turbo and he has 230K on his engine and I have 156K. I continued to the drive the truck another 2500 miles and didn't notice any oil loss on dipstick. My big concern is I use this truck with a 4500 pound (Lance 1172) truck camper and a trailer and I'm afraid of getting stranded if the turbo oil seal suddenly lets go, are these turbos know for oil seals failing or I'm I just worrying to much?

Normal.
Boogie on.

When you start seeing a loss on the dipstick (other than the normal 1/2-1qt @5k-7k miles), then take notice....maybe.

Simple green and a water rinse will clean it all up.

I agree with @hook’em_horns it’s the Pcv system. Reroute it. And never worry about it again.
