Hi, 2009 X5 3.0si, changing valve cover gasket and others.
Tested PCV (built into valve cover) and will not hold suction.
All I've read is that it is not replaceable(must replace valve cover).
I've seen decent hacks on V8 X5's and they have a replacement.
Hard to believe with the popular 3.0 that there isn't a PCV replacement.

If there is, does anyone have the part number and where to buy?
I've checked all the major suppliers, Pelican, RM, FCP Euro, etc, NOTHING!

Any ideas?

Thanks,
