OK I have a Kinroad Sahara 150cc buggy, IM having issues with oil coming out my oil breather, and it comes out enough to make a mess. Could this be blowby? My engine doesnt smoke that much, it smokes very little just enough to see it. Ive been thinking about rebuilding the top end. New piston , rings, cylinder, new head with valves. was just wanting to know if there is anybody out there that has had the problem with oil coming out there oil breather...please i need some good answers here......
