So my wife is getting sick of the burnt oil smell, so I need to do the valve cover gaskets.
The X currently has 155k miles. It's a 3.0. I've never really had to do anything to it. I put a disa valve in at 65k, replaced the ccv at 140k (cold weather vs.).
Should I mess with the vanos?
I don't really see any of the symptoms that I've read about. Only issue I have now is a hard start issue. If the motor is cold, or off for a couple hrs, it takes forever to start. Just sits and cranks. If I try starting it, then stop, and try again, it will fire right up. But if I just hit the key and hold it, it will turn over for a good 15 sec or more.
Could that be a vanos issue? Seems more like a intake cam sensor issue, but there is no cel?

Also, should I bother with the intake manifold gaskets? Never been touched. I know on the m62 the intake rarely lasts longer than 130-150 before you start getting leaks. Is the 3.0 the same?

Thanks in advance for the tips.
