Mine is not hooked up to the CAC and I started the truck and idled it for around 5 minutes. The passenger side of the engine compartment was sprayed with oil in the short time I ran it that way.

Open imap sensor and look if it vacuum sucking or blow air.

I’m on the same issue. Probably turbo rebuild again.

Also, check oil drain hose, air filters, position turbo at idle, oil you use, crankcase pressure or blowby pressure struggling oil to come out, air compressor.
