Re: 8BA cam position
So I tore into the motor today, removed the rod caps and plastigauged the gaps on all, everything is .002 even one of the main caps was .002. Still no sign of what would cause a knock. I cut short pieces of hose and installed them on the rod studs to protect the crank. Then pushed the piston up in the bore to check for any movement in the wrist pins, there is not any slop that I can tell. Looking at the rod bearings there is some wear, should I replace them even thou they gap well with in specs?
I also noticed the rod cap nuts have a groove around them that were facing up when install. What is the purpose of that?
