This question isn't about my Duc, but should apply to all makes and types. I have an '84 Honda Ascot that has an oil leak. It leaks while it's sitting (not running), and will lose ~5 drops over night. I've cleaned the engine so it's nice and shiny to help see where it's coming from. I have been able to narrow it down to the lower left side of the engine, but can't pinpoint. I was thinking about dusting it with baby powder, but was wondering if there are tips or tricks others here have used. Any advice is appreciated.
