My srt is doing the same exact thing yours is doing and i literally just had all my valves, valve guide seals, and head resurfaced. after doing some research i have discovered that if the turbo is not draining its oil out the center cartridge due to a clog somewhere it will cause the oil to backup inside the turbo and leak out the turbine side where it than ends up into the vacuum line that leads directly to the intake over by the throttle body. I have not confirmed weather or not this is the answer but my asshole mechanic used silcone on my oil drain as a gasket which ended up blocking 70% of the drain tube. atm im in the process of getting a real gasket and putting it all back together.
My idea though is to just disconnect that vacuum line and see if the car still smokes after that (dont drive it, i believe that vacuum line also goes to the brake booster) just rev it up in your driveway or something. my car has the same exact symptoms as yours. its perfectly fine at cruising no matter what rpm im in but if i step on the gas i get massive smoke and a nice spray trail behind me and there is no physical way that much oil is getting past my piston rings with 160psi across the board. Oil pressure builds when you boost or have any kind of motor power being produced, it only makes sense the turbo is getting fed alot more oil during those periods and if its not draining the fluid fast enough it will begin to go wherever it can escape from and it just so happens the intake will just suck it all up super quickly when the motor is looking to pull more air (or boost) in
