Silly way to write a rule.
Why is it so hard to just come out and have it black and white, no its ands or butts.
First it said towards valves, now it says valves/ lifters.
Unless they are trying to say it can't be on the crank side.
The arrow can only point two directions toward the lifters or away from the lifters, the rule says toward the vaves/lifters remove the word valve rule will be clearr?
