I would say that the pump seizesing is the most likely cause or the push rod itself, with the pump and pushrod removed, remove the spark plugs and check that the engine can be turned by hand freely, check for the presence of oil around the pushrod hole and finally gently rest a cross head screwdriver in the pushrod hole and slowly turn the engine by hand, the screwdriver should rise and fall ( only a small amount of movement will be noticed - 10 to 20mm ) . I f this is the case then the fault is probably due to a seized pump either the lever arm failure or a valve failure causing the pump to hydraulicly lock.
