Hey. I'm tired of buying 35$ bottles of oil to the gearbox, and wonder, what csn be done to stop leak without opening the gearbox? 00grease or is there a way to make it stop leaking? My thought is that you can put some stuff/chemicals ina car engine to stop leaks in water and oil, would this work on the leaky bladder of this gearbox? The Norwegian kr is low in value so everything with a dollar sign is crazy expensive nowadays. Input?
