StartX5. Just wondering if you recall your odometer reading when you completed your Vanos seals project?

I have the same 2004, X5, 3.0i, M54 engine and I'm sitting on 90K miles. I'm preparing for a valve cover seal replacement job to kill a tiny, but seriously annoying, oil leak from my valve cover (just over the exhaust, so the drip hits the hot pipe and turns into smoke and a complaint from the wifeepoo). It's been there for over a year now likely due to a failing oil separator that I replaced a few month back. Enjoyed your most excellent post on the valve cover gasket - a shot of a hot chick or a good joke is the only missing element

Bottom line, since the valve cover job looks like 40% of the Vanos job, and I have 90K miles on the engine, should I just pony up the time and kill the Vanos seal job? Bonus round question - it appears that the Vanos position sensor will also be in the clear, should I just swap it as well?

PS - the small cost of the parts is not an concern since I value driving piece of mind and one less thing for the wife to mention (not that she can't notice other things "wrong" with the X5 and then ask for a new one all in the same breath - normally triggered by a sighting of a new X5 which seem to be the official taxi here).

Thanks in advance for any advice. Mahalo,
