Mr Gasket Crankcase Evacuation System Reduces pressure buildup in the crankcase

Designed primarily for drag race applications, this crankcase evacuation system is designed to reduce pressure build-up in the engine crankcase. This provides a better piston ring seal, less intake charge contamination, and reduces oil leaks caused by high crankcase pressures, while increasing engine performance. Kit includes two chrome plated Mopar style push-on valve cover breathers, two breather grommets, two check valves and two 3 1/2" long, 45 degree cut/threaded tubes, which must be welded into collectors.
