Blow by is caused by Bad PCV system or piston rings and or piston ring lands being broken.I would first check the Pcv system for vacuum ,if that is ok then I would dump some cleaner down the carb when hot, let it sit for 1 hour then go drive the piss out of it. http://youtu.be/t0OVIsU01mg 6846625-Lisasamoa5.jpg (479 downloads) http://youtu.be/fAP_2rxz_GA
