as far as the accusump opening and closing often, it will not
harm the valve, thats what it is made to do, as far as it opening,
when you pull up to a stop light or at idle it shouldnt be a problem
as the engine should only take the oil in from the accusump as it is
needed, if it is not beeing "pulled in" by the engine it shouldnt
really push to much in
