2006 550i roller drag lever locations
 

Hello,

Some of the roller drag levers (rocker arms) popped of when I was changing out the valve stem seals and me not knowing that they were different tolerances I just popped them back on anywhere they were missing. I started the motor for 5 sec and shut it down when it didn't sound right. The results could have been much worse but nearly all of 2b rollers on the exhaust were broken on both bank1 & bank2. Everything on the intake for both banks is fine. Could incorrect timing cause all of these to break like this or would just one roller in the wrong spot cause everything else to fail? I know I didn't take them all off and I need to find a diagram showing which roller tolerance 2a, 2b, 1 or 3 goes where. I've looked online and in my Bentley manual I can't find this info anywhere. I'm going to replace them but I have to know where they go so as not to repeat this again. Anyone with this info please help I'm totally stuck.
