This kit helps ensure that the oil tank remains vented if the rollover valve freezes shut. The kit vents the oil tank to the valve cover so in the event of a rollover any oil that escapes the oil tanks drains right back into the engine. Kit includes cap for oil tank, cap for valve cover, hose and clamps. Fits Sidewinder & Thundercat ZR9000
