Today I decided to investigate. I got my locking pliers and gripped the clip on the little drain plug at the bottom of the airbox (?). The drain and the rubber cover snapped off in my hand. The good news is that a cupful of oily water (watery oil?) came out as soon as it was opened.
What is the drain plug for?
What does it mean to have the liquid in there?
Can I just superglue the bit back on?
