Sawman,
I just realized that, if you have not used the one-shot oiler, you should not have any oil on your drive. (At least not under the front corners.) The oiler should work only if someone depresses the oiler button, so it could be that your one-shot mechanism is starting to fail, which might lead to catastrophic loss of oil. (But the one-shot on my '61 +4 is 51 years old and works fine.)
