CANTON 22-220 SBC LIFTER VALLEY VENT

SBC Lifter Valley Vent Tubes are designed to be installed in the eight lifter valley drain back holes. These 2" tall vent tubes reduce crankcase pressure by allowing air to freely pass through but not allowing oil to drain directly onto spinning crankshaft absorbing horsepower and increasing temperature. The oil is redirected to the sump through the timing cover and rear block holes. Sold in a pack of 8 per set.
