Mr. Gasket Crankcase Evacuation System

Built primarily for drag race applications, this system is designed to reduce pressure build-up in the engine crank-case. The results are better piston ring seal, less intake charge contamination, and reduced oil leaks, while increasing engine performance. Includes two chrome plated push-on valve cover breathers, breather grommets, check valves and 3-1/2'' long threaded tubes. Tubes must be welded into collectors.
