They do get pretty dirty but the OCC helps a lot, the N54 get a lot of oil blow back from the crankcase and all gets dumped to the rear turbo and eventually makes it was to the intake ports.
I think is great that you are doing this for a great price, I've heard the dealership charging over 1k to do this same job.
