The MCX surge tank is a air - oil seperator .
You are correct except for oil is drained from the tank to the small vent line to valve cover.
When engine is upside down oil from valve cover will go into surge tank and then leak out surge tank vent .
This is why we install valve on end of surge tank vent.
Jeff ,nice pic of you in Snow Rider Mag when you where at the Intermountain Snow Show .

Thanks Mark. We will make the appropriate adjustments to our install instructions.
BTW, your pic was much better than mine... I kinda looked like a rosey cheeked, pregnant gopher in mine!
