BMP Aluminum Lifter Valley Vent Tubes

Keeping debris out of your oil system is a job for Bill Mitchell Products lifter valley standpipes. These small tubes plug the oil drainback holes of your engine block to keep oil from draining back down over the camshaft but still allowing the crank case to breath. They can be quickly removed or installed with an Allen wrench.
