Didn't lose any water. Holly shit.... Was water supposed to be there? I just took a 12mm to undo the two bolts, took off the connector, blasted it with carb cleaner, let it sit in the balcony, and put it back in hours later. The gasket sits flush inside a groove, and was perfect. Just reused it. I made sure I disconnected the battery and started up w/out hitting the gas. (As you should do anyway)
