Hi, I am working on a V6 engine from this video: https://youtu.be/Bp2Cc_iriWM?list=PLfP1GxQ1lPaSWOY7biDuGwAnmmQplrREZ&t=989

I need to set up cam mates with a number of rocker arms like this : http://puu.sh/iQhWS/7f6158a365.jpg

The first one works perfectly, but upon as the cam shaft rotates, the rocker arms after the first one keep going UNDER the cam shaft for some reason: http://puu.sh/iQi43/035a35db4a.jpg

This is the zip file: https://drive.google.com/open?id=0B2oiT5d2gFWaZGlUQ0FDZ1JiRDQ[4]

The assembly file's name is FINAL ENGINE.
