new cap fitted, still blows off, cleaned the breather pipes and pot out and put a bottle where the filter is at the end of the breather, next to nothing in it since thursday.
there is a little smoke from cold start up which id say is the valve stem steals, easy sort, no smake on or off throttle. left it ticking over for 10 mins yesturday and there wasnt a puff out the exhaust.
its not used oil and its not blown the dipstick out either

one way valves in the breather pot?
