I figured it was CCV when I first saw it but after reading some of these threads I am now freaked out. I really hope it's my CCV's and not the valve stem seals.
I love my X5 and hope it gives me several more years of non issues as it has the last 72k.
Beside replacing the CCV's should I replace anything else corresponding?
Thanks,

I think CCV's are the place to start. I may still remove and clean my valve covers when I have time, but I'm happy currently with the sludge removal and the CCV's being replaced. My mechanic claims it's almost always CCV's
and the valve covers though. They just replace them and pass the $800 part cost on. If I get to it, I'll remove and clean them instead myself.
I can't imagine valve stem seals being an issue at 72,000 miles...
