Larry the cover has a very small gasket that is in the cover. Also I used a hand mityvac to syphon it out at 500 mile, but now at 2400 needed to pull the cover to check every thing over... all looks well on mine[emoji106]
Looks to me the gasket is reusable![emoji1]If you take the cover off, is the gasket reusable? I plan on doing mine with a syphon I use on my waveunner when changing oil.
