I have been rebuilding a 2017 5.0 for a neighbor and once I got to the camshaft timing portion of the rebuild I noticed something odd with the VCT assembly.
I had no issues getting the LH (drivers side timed in) but once I got to the RH side I noticed something odd with the intake VCT assembly (although seated onto the cams as it should be). The VCT assembly wasn't turning the intake camshaft the same rotational degree, it was turning it less. Initially this would have led me to believe the assembly wasn't seated into the slot in the cam but that wasn't the case. I pulled the RH phaser assemblies off of the cams and decided to take the intake assembly apart and this is what I found.
It looks as though a piece had broken off of the pin and has been slapping around inside the assembly ( see nicks in photos).
This thread is just an FYI for anyone rebuilding and trying to time their machine. If this happens I wouldn't hesitate to suspect a VCT assembly.
