From all the posts on premature cam wear/failure it looks like I am not the only one.

I knew from the start at the engines first oil change to use the right oil and best oil available due to the narrow cam issue of the 05.5-06 Jetta TDI cam.

This engine has only seen Amsoil 5w-40, vw 505.01 oil but I am still seeing premature cam failure at the 119,000 mile mark. There is a noticeable ridge developing in the cam but only on every other lobe of the cam.

Looking at the forums I do not see any chatter of upgrade or additives to help with the wear issue or are there any for this problem?

Thanks ahead of time for any replies.

Maybe if you removed it and polished the edges that might help. Using thicker oil always helps. Colt does a cam regrind if it's not too bad and it supposedly adds a few hp.
