Funny, I just opened mine up to find the culprit of my -9 on one bank and was puzzled to see the first pad looking just fine. The I turned the tensioner over to see the 2nd pad and whoa! Looked just like that sucker in the picture!

This is what happens when people drive a Porsche like a Honda, or Toyota or Buick Skylark.. Easy driving keeps the VVT arrangement in the "loaded" position at all times and increases the forces these wear pads see.

Men can also drive like females, and they wear these components out way early as well. We have actually seen these wear so thin that they break in half.

Thanks for all the info. Time to start looking for tensioner pads...

Ha ha! That explains a lot! When I bought this car in the spring, the p o almost had a fit when I punched it on the test drive!

Mine is at the -6 limit as well.

How big a DIY job is it to replace the tensioner pads?

Can it be done with the engine in place or do you need to drop the engine?

My bank 1 values vary greatly from hot to cold. Dead cold, its at about - 6.5, fully hot engine (after running for more than an hour) it comes down to under 5.5. I'm not digging into the motor until it gets substantially worse, and it been about the same in the 25k miles I've had my car.
