So with the rotation of the valves (due to either the rotators or an off centre lifter / cam configuration) a particular direction of movement is encouraged right?
If this direction of motion opposes the tightening of the lock nuts on a valve stem the clearance would tend to become looser with use right? And if the direction of valve rotation goes with the direction of tightening the lock nuts then the valve clearance would become tighter with use - right?
Does this sound possible or feasible?
I once heard a story of someone revving his motorcycle engine so hard that the valves got so tight the cylinders wouldn't hold any compression - myth, legend, BS - I don't know...
