Review BIG END PERFORMANCE Crankcase Evac. System

The Big End Performance 70360 Crankcase Evac Kit is an essential upgrade for any high-performance engine, designed to improve oil circulation and enhance engine durability. This kit is specifically engineered for small-block Chevrolet and GM engines, and is a must-have for those seeking to maximize power and efficiency.

At the heart of this kit is a high-performance crankcase ventilation system. The 70360 kit includes a baffled crankcase vent, which is designed to prevent crankcase vapors from entering the intake system, reducing oil consumption and improving combustion efficiency. The baffled design ensures that the vapors are properly directed back into the crankcase, where they belong, minimizing emissions and optimizing performance.

Additionally, the 70360 Crankcase Evac Kit includes a compact, high-flow oil separator. This separator is designed to remove moisture and contaminants from the crankcase vent stream before it enters the intake system, ensuring that only clean, dry air enters the combustion chamber. The separator is also easy to install, with simple bolt-on design and minimal modifications required.

The 70360 Crankcase Evac Kit also includes a high-performance crankcase pressure relief valve. This valve is designed to relieve excess crankcase pressure, preventing damage to the engine caused by high oil temperatures or vacuum conditions. The valve is adjustable, allowing the user to fine-tune the pressure relief setting to suit their specific engine and operating conditions.

The Big End Performance 70360 Crankcase Evac Kit is made from high-quality materials, including billet aluminum and stainless steel, ensuring durability and resistance to corrosion. The kit is also easy to install, with clear instructions included, and all necessary hardware provided.

In summary, the Big End Performance 70360 Crankcase Evac Kit is a must-have upgrade for any high-performance small-block Chevrolet or GM engine. By improving oil circulation, reducing oil consumption, and preventing crankcase vapors from entering the intake system, this kit helps to optimize engine performance, enhance durability, and maximize power output.
