How to replace piston rings! I replace the piston rings in an Iseki TX 1300 mini tractor. This process is basically the same on gasoline and diesel engines. The engine in the video is a Mitsubishi KE70. The engine would not longer start because of low compression and I started to see oil in the coolant. It has gradually lost power and being harder to start before it would no longer start. I thought it was just a bad head gasket, but the engine also needed new piston rings to get the right compression. Also change the oil, coolant and radiator rinse, new air filter and some other repairs!
