Hi all Quick one, are these ball bearings supposed to move? Im assuming they let oil into the camshaft holder to distribute oil into the camshafts? Cheers
They might have been used to block off the oil gallery after machining. Note the indents to hold the balls in place.
Once an intersecting passage way is drilled it's just simple way to block it off again. They use the same idea to block gallery's in some carby's etc too
