Building a new 505 With Callies / Mopar Performance Block
Andy
The cam plug is out. Brand new Mopar block timing cover surface is clean, new timing cover surface is clean. New gasket measures .032 before torquing. Oil pump shaft is installed. The timing cover is torqued down to the block. Cam button is properly assembled using break in oil for lubrication it measures .640 assembled. The only thing that maybe throwing off the measurement is there a specific torque for the torx bolts for the cover or access plate also the o rings are installed in the cover if that makes a difference.
Edited added cam button assembly.
Cam button. Item one fits snugly (slight tap to make it seat completely) in the cam gear, then shim item two is installed, then item three thrust bearing is installed, then shim item four installed and last top piece item 5 installed with the bevel pointed to access plate.
