I have 0 oil consumption for the 3 years I’ve had the car aside from spark plug tube leak. However that’s never made a quantifiable change in oil level including now.

Also no to cleaning out the intake. I think all the residual oil is burned off already. It’s been a month or more since the AOS was swapped out and for the few days following it I saw some smoke out of the tailpipe but nothing after that unless there’s a pool of it that’s remaining until higher vacuum force from high RPMs suck it in.
