they send the return oil down a very narrow passage that's part
of the concentric tube design. That gets plugged and then instead
of returning oil, it burns it. Dip tube was totally blocked with that
mayo when I replaced my CCV. I'd do the CCV every 75K and not
worry about the mayo on the cap.

I'm doing this next week:
The Permanent M54 CCV Delete - E46Fanatics
Sourced the aluminum valve cover, oil dipstick tube, connecting hose, and plastic cover that goes on top for $150 from some guy on CL. Valve cover gasket set for the M56 plus a few other parts are on the way. Rebuilding VANOS at the same time.
I imagine rebuilding the VANOS, replacing my CCV system with a superior solution and fixing my leaky VCG all at the same time will provide quite an improvement in engine response.
