This is happening to me as well. Not sure of the root of the problem.
I do have a Sxth oil catch can installed and reach out to them. Their team had me check the installation was correct and that the O-rings were sealing properly. All seems to be good there.
I also have an Afe Power Takeda stage-2 cold air intake. There's a hose routed to or from the intake tube that's very loose. Not sure if that has anything to do with the oil smell but I haven't done any other mods or made any other changes to the car.
Very interested if anyone else has had a similar issue and what the solution is.
