I took a 6.0 and board it .060 over all forged i put everything back together started it and i had a lifter tap so i took everything apart and put a new lifter in it and the exact same one is tapping what seems to be the problem. Its the only one doing it need some help to solve my problem.

 

Hey, we rebuilt my friends 6.0 , except we did a .030 over and its doing the same thing. If you happen to know what the problem could be, please let us know. We will do the same. I am sure someone will help us.

 

How do you know it is just one lifter tapping?
