Reduced Catalytic Converter life requiring replacement runs +$2,000 each.Progressive and Exponentially Impairs Performance Without a Oil Catch Can this Condition Is It is engineered to eliminate valve coking issues, increase fuel economy by eliminating oil associated detonation, reduce tailpipe emissions, and prolong engine life by removing damaging combustion by-products and trapping them from entering into the intake air hose connected to your McNally Gen 2 Catch Can. McNally Gen 2 Oil Catch Can is a true oil PCV crankcase evacuation and separation system. This 'Blow-by' results in loss of power, detonation, and long-term burnt carbon buildup on the pistons and valves reducing the air velocity and flow through the engine which keeps the engine running cooler. Because a GDI engine is a closed system this oil, sulfur, and waste carbon, referred to as 'Blow-by', naturally finds its way into the air intake system. Understanding the Need for a Proper GDI Engine Oil Catch CanД®veryday vehicle use of a Gasoline Direct Injection (GDI) engine will cause the build-up of a certain amount of oil, sulfur and waste carbon into the intake air system. At McNally we believe we have come up with the most innovative and efficient design of any oil separating catch can on the market today. Centrifugal force pushes the particles against the now thinner, cooler side walls of the oil catch can and condense faster to collect more blow-by byproduct. As the contaminants enter into the can the proprietary internal design of the cans separation apparatus force them into a spiral motion. Next, the new McNally Gen 2 Oil Catch Can uses thermal differential and centrifugal force in addition to coalescent filtration.

First, we use coalescent filtration to remove the majority of harmful contaminants that diminish the performance and longevity of your engine over time. The McNally Gen 2 Oil Catch Can have features which put this can a step ahead of the competition. With the Gen 2 design, our proprietary check valves are built into the catch can, making installation faster and easier. Our old design needed the installer to cut the hose in order to insert in-line check valves and it was crucial that they faced the correct direction. First, Let us start with the check valves.
