The Lifter Valley Vents SBC 1/4in NPT 8pk from ALLSTAR PERFORMANCE is an essential engine breather accessory designed for small-block Chevrolet (SBC) engines, specifically addressing crankcase pressure buildup during operation. This product is crucial for preventing oil sludge accumulation and extending the life of your engine, whether you are working on a stock rebuild or a high-performance build.
Each vent features a 1/4 inch NPT (National Pipe Taper) connection, which is the industry standard for engine block breather ports on SBC small-blocks. This eight-pack configuration allows for addressing multiple breather locations or maintaining a spare inventory for future builds and repairs. The NPT thread design ensures a secure, leak-free seal when properly installed with thread sealant, preventing unwanted oil vapor escape.
Mechanics and engine builders will appreciate this multi-pack offering when installing new cylinder heads or refreshing top-end gaskets. Installation is straightforward: simply thread the vents into the designated lifter valley ports on your small-block head, apply appropriate thread sealant, and torque to specification. These vents are compatible with small-block Chevrolet engines ranging from 265 to 400 cubic inches.
