I finally got the cam followers from Chicago BMW. As I suspected I was not successful in pinning the chain tensioner and am finding it more difficult than expected. I can push the tensioner pretty far down with screwdriver but cannot get it to stay. What size is a #30 drill bit? I have been trying allen wrenches down to less than 1/8 and cannot get any to start. Maybe too much oil still in it. I cannot spin the motor over now that cam sprockets are off to remove excess oil. Any ideas? -------Rethy
