90% of the new motors I see pissing oil out of every seal/ gasket or the stick are either only runnung 1 breather or none. All of them resolved the problem(if caught soon enough) by installing some sort of Positive Crankcase Ventalation system on it. Either a conventional PCV valve setup or moroso Vac-U-Pan kit or a vacuum pump, but something has to create negative pressure in the crankcase for everything to seal properly. 2 breathers won't create negative pressure & will likely still leak.
