my uneducated guess is that when the float sticks petrol gets into the inlet
manifold at ahigher quantity than usual and might thus dilute the oil. to
check for a sticking valve you just need to take off the valve cover and
turn the engine by hand, you should be a ble to see every valve going down
in turn as per valve setting instruction.
Good luck.
