Crankcase Evacuation Sys

The MR. GASKET Crankcase Evacuation System (SKU MRG6002) is a weld-on breather kit engineered to manage crankcase pressure and prevent oil blowby in high-performance and modified engines. This universal system is ideal for street rods, racing applications, and custom builds where factory ventilation falls short. By safely routing crankcase vapors away from the engine, this evacuation system reduces pressure buildup that can damage seals, gaskets, and bearings while improving engine longevity and reliability.

Constructed from durable steel, this crankcase evacuation kit features a weld-on design that provides a permanent, leak-free installation on custom fabricated or modified engine blocks. The system includes essential components—breathers, grommets, check valves, and nipples—all rated for 5/8 inch hose connections. The integrated check valve prevents backflow and atmospheric moisture from entering the crankcase, while the breather design minimizes oil carryover. This comprehensive kit approach eliminates guesswork and ensures all necessary fittings are included for a complete installation without additional sourcing.

Enthusiasts, hot rodders, and performance engine builders benefit most from this universal system when upgrading older carbureted engines, boost applications, or high-RPM builds where standard factory breathers cannot handle elevated crankcase pressures. The weld-on mounting requires basic fabrication skills or professional installation on the engine block or custom pan. With compact dimensions of 5 x 3.7 x 9.6 inches and a lightweight 1.45 lbs, this evacuation system integrates cleanly into tight engine bays. Whether you're rebuilding a classic engine or optimizing a modern performance platform, this MR. GASKET crankcase evacuation system delivers proven protection and reliability for sale online and in-store.
