Thanks much for you input!

I didn't have any VANOS issues or symptoms either when I overhauled it on my M54 X5 last year (with about 96K miles on it at the time). But I figured "while I'm in there" doing my VCG, it's only about $120 worth in parts (seal & rattle kits), I will never have to wonder about it again since the seals are already at about 100K life. The engine has been idling like butter now.
I'm planning on doing a similar overhaul on my S54 MC on the next inspection when doing my valve adjustments.
