I just want to get to the bottom on why the cams are failing in the common rail trucks? I might also add its not just one cam supplyer its all of them!!
I'd think if there were a bunch of cams failing... there'd be a lot more talk about it. I've not seen anyone... recently anyway claim their cam has failed. I've also not seen any aftermarket tappets that claim to be better than stock. You say there's wear after 10 miles so what's going to be different if they're changed ? In 10 miles they'll be worn again.

Since I've changed to 110lbs springs a billet tubes, I do expect more than normal wear but, see no reason to upgrade tappets although the one's I have are only a year old. Guess I'll find out once I pull the cam.
