If you own a GDI (Gasoline Direct Engine) then you need an Oil Separator Catch Can.
McNally Gen 2 Universal Oil Catch Can and Catch Can Kits
What is a Catch Can and why do I need one?
The McNally Gen 2 Oil Catch Can will Save You Thousands of Dollars in Repair Costs and extend the Life of Your direct injection engine.
There is a problem today with Gasoline Direct Injection “GDI” Engines. GDI Engines produce "blow-by" that over time will slowly cause your engine to coak up and lose performance, reduce mileage and ultimately damaging your intake valves in your engine.
Installing any of the McNally Gen 2 Oil Catch Can Kits will reduce this damage caused by Gasoline and Diesel Direct Injection Engine blow-by. Our gen 2 Oil Catch Can Kits provides continuous cleaning of the intake air with every mile and in every driving condition for the life of your vehicle. * The Catch Can must be drained on a regular basis; it is suggested every 3k to 5K miles.
McNally gen 2 Oil Catch Can Kits are a true oil PCV crankcase evacuation and separation system that is engineered to eliminate valve coking issues, increase fuel economy by eliminating oil associated detonation, reduce tail pipe emissions, and prolong engine life by removing damaging combustion by-products and trapping them from ingestion via the intake air charge.
Direct Injection Engine Oil Catch Cans:
- Eliminate Engine Coking
- Maintain Engine Performance
- Keep Your Engine Running Cooler
- Maintain Fuel Efficiency
- Designed for all Types of Gasoline and Diesel Forced Induction Engines
Understanding the need for a proper designed PCV system Catch Can
Everyday vehicle use of a Gasoline Direct Injection (GDI) engine will cause the ingestion of a certain amount of oil, sulfur and waste carbon, etc. into the intake air system. Because a GDI engine is a closed system, this oil, sulfur, and waste carbon, etc. referred to as Blow-by naturally finds its way into the air intake system. This Blow-by results in loss of power, detonation, and long-term burnt carbon crystal buildup (coaking) on the pistons and valves reducing the air velocity and flow through the engine.
McNally Universal Oil Catch Can Kits are a true oil PCV crankcase evacuation and separation system that is engineered to eliminate valve coking issues, maintain fuel economy by eliminating oil associated detonation, reduce tailpipe emissions, and prolong engine life by reducing and removing damaging combustion by-products and trapping them in the catch can and keeping the from ingestion via the intake air charge.
Without an Oil Catch Can this condition is progressive and exponentially
impairs the performance of the direct injection engine by:
- Reduced horsepower and torque
- Contaminated Catalytic Converter(s)
- Reduced Catalytic Converter life requiring replacement runs +$2,000 each.
- Fuel Mileage efficiency
And an increase in maintenance costs; intake mechanical cleaning can run from $1200 to as high as $2,000 and up, EACH TIME. Chemical cleaning is MUCH less expensive however it sometimes can create other problems via corrosion and even worse may eventually force the purchase of new Catalytic Converter especially if the cleaning is not properly performed by a certified mechanic.
Preventing or mitigating this challenge to your vehicle requires some engineering modifications such as adding a McNally GEN 2 Oil Catch Can to the closed Original Equipment by Manufacturer (OEM) Positive Crankcase Ventilation (PCV) system.
The bottom line is, without a proper evacuation system you WILL sustain long-term and expensive engine damage. This damage begins on a direct injection engine day and mile 1 and progressively gets worse. The McNally Gen 2 Universal Oil Catch Can Kits catches these harmful contaminants. The catch can should be drained at every oil change interval in compliance with the vehicle owner's manual maintenance schedule or every 5000 miles which every is sooner.
