Hi all, it has been a long time. My father purchased what we believe to be a 1949 8N with a 2/9N hood with the intake stack sticking out of the hood and a 2/9N front axle with 2/9N front hubs. The serial number on the engine along with the rest of the tractor, transmission, rear axle, etc point to it being a 1949. It is still a 6V tractor. The engine seems to start well and runs well, with good oil pressure, but she smokes like crazy out the tailpipe and oil breather tube, which I believe indicated bad rings. Is this correct? What should our next steps be? Compression check dry and wet and then possibly ATF soak?
