i realize they are not related to VANOS...just wondering what kind of maintenance should be done with my mileage (90k). i just purchased the truck a few months ago. figured since i'll be in there pulling the engine bay apart enough to remove valve cover and VANOS, i may as well do whatever i can at that time. all the things i mentioned so far seem simple enough that it would be dumb NOT to do them all at the same time.
but back to my original question, does anyone else concur that the noise is most likely VANOS related?
