Vario cam tensioner pad

I see the same thing, although the amount is really very minimal. Many others see the same thing. I'm not really worried about it.

The best thing you can do to minimize wear to the pads on the Vario-Cam engines (2000-2002), besides the obvious maintaining oil quality, is to avoid cruising in the changeover rpm range of 2200rpm- 2500rpm





They usually wear this much after 40K to 80K miles & cause the changeover to be less smooth enough to see a power drop on a dyno chart @ that rpm. Eventually the pad can deteriate enough to crack & break causing excessive camshaft timing deviation & Eventually chains coming loose. So it's a good idea to install the new more wear resistant wear pads before 80K miles.

Excellent! I have always avoided stop and go traffic as I had feeling it was loading and loading chains....now I know

I actually thought there was a phasing at 4K.

So there are more robust pads that are available...this good news...are they 996 part number revisions? When is someone going to design "metallic" roller pads??

I will have to have to have the facilities and know how to drop the engine by then. Once I have that can this work be done by a non expert?

Vario-Cam is a single timing change @ 2200-2500 rpm & it really helps from 4000rpm up. There is a update kit containing 2 pads & 1 o-ring to do 1 Vario-Cam tensioner so you need 2 kits. The wear pad has to be softer than the chains so that the pads wear & not the chain. The cams have to be removed & re-timed so you need special tools

Thanks for the information...I have heard that cam timing is pretty tricky
