Cam gone flat? Here's a interesting video.

The old Mopars that were used as Police Duty didn't have this problem. If they did they would have worked out the problem, especially since warranty work would be involved. Cop cars and taxis did a lot of idling, although most cabs were sixes. Cop cars idling waiting for you to go speeding by with their Radar gun pointed at you. So it would seem that the biggest difference today is the removal of the zddp from the oil. And like anything else an occasional bad cam or lifter could be the reason for some of the problems. So at this point we still don't have a definite reason for the problems some people have encountered. I'll go with the oil with the added zddp and keep my fingers crossed.
