Just wondering, I have a slow drip of oil coming from the gear lever shaft outlet on the case. It's not huge, when it gets warm it drips more, when I first shut the motor off it's considerable, when it's cool it drips less, when it's cold/not running it doesn't drip. I think it's just an O-ring, but 1. I don't have an o-ring (yet) to replace it 2. I don't want to go digging out the existing if that's not the correct fix and get myself in deep with a larger repair.
