[QUOTE="Unicycle52, post: 412293, member: 669"] I would suggest you replace the tensioner (or have it replaced). It has very fine teeth on it to hold the adjustment and they wear. If you attempt to adjust the current tensioner the teeth may not hold and if the cam chain tensioner slips out of adjustment and throws the cam timing out of position it can be a mechanical disaster (as experienced by another forum member). The knowledgeable mechanic that did mine under warranty also mentioned that part of the tensioning operation is assisted by oil pressure. Make sure your idle isn't set below 1100 rpms. Mine was replaced at 40K but I'm pretty sure it started making noise 5 - 8K before replacement. At idle you could hear it get noisy then quiet then noisy. They are known to need replacement around 35K. Hope this helps. Bill Hamilton [/QUOTE]
