GY6 150cc Crankcase Gasket

Keep your GY6 150cc engine sealed up tight with this crankcase gasket. It sits between the left and right crankcase halves and keeps oil where it belongs instead of weeping out around the case seam — a common issue on high-mileage or recently-opened-up GY6 short blocks.

If you're already in there for a top-end rebuild, a stator swap, or a crank replacement, this is a cheap-insurance part to replace on reassembly rather than reusing the old one. Gaskets compress and take a set the first time they're torqued down — reusing a used one is asking for a leak down the road.
