What kind of warranty does RND have on their engines? 2 years and 23k miles seems odd to have this kind of wear considering your oil change regimen.

The 2000 VarioCam system is a pretty simple on/off setup. The exhaust cam position is fixed relative to the crank, and the intake cam position moves a fixed 24 degrees relative to the exhaust cam. The movement of the tensioner is reversed for the 4-6 head. At approx 1,500 rpm the cam solenoid/tensioner moves to advance the intake cam, and at 5,500 rpm it returns to the original position.

Hmmmm so the 3K rpm and above driving threshold has no vario cam wear benefits? (for 2000 3.2 S engines )
