The McNally Oil Catch Can Just Got Better!

This new design has many new features greatly improving it over our Gen 1 can. While sticking with an oil catch can design that looks familiar, we’ve added some Bells, Clicks and Whistles we think you’ll find impressive. We’ve finally added quick connect fittings to the top of the can, speeding up the installation process and making it simpler. This was the first thing we wanted to do, so we finally did it! Another feature we added was getting rid of the typical drain valve on the bottom of the can which is hard to reach in most tight modern engine bays. Now we have a release knob on top of the can, just pull it up to relieve the reservoir of the condensed byproduct. This makes maintenance so much easier and it keeps your engine and garage floor neat and tidy. Not only is the release valve on the top but now there’s a level indicator window to let you know when your can is full of contaminants, so no more guessing.

11.5 inches in height and 4 inches in diameter.
McNally Universal Gen 2 Oil Catch CanNow for the fun stuff. First, Let us start with the check valves. 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. This created a lot of confusion. With the Gen 2 design, our proprietary check valves are built into the catch can, making installation faster and easier. The McNally Gen 2 Oil Catch Can have features which put this can a step ahead of the competition. First, we use coalescent filtration to remove the majority of harmful contaminants that diminish the performance and longevity of your engine over time. Next, the new McNally Gen 2 Oil Catch Can uses thermal differential and centrifugal force in addition to coalescent filtration. As the contaminants enter into the can the proprietary internal design of the cans separation apparatus force them into a spiral motion. 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. 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.
The addition of these two features, will give our customers confidence knowing that their McNally Oil Catch Can is doing the job right!

Designed for all Types of Gasoline Direct Injection (GDI) and
Diesel Forced Induction (DFI) Engines

The McNally Gen 2 Universal Oil Catch Can
will Save You Thousands of Dollars in Repair Costs
and Extend the Life of Your Engine.


You will receive 3 quick connects and 2 foot clear drainage hose.

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 coke up and lose performance. It will reduce mileage and ultimately damage your intake, valves and pistons in your engine.

Installing any of the McNally Performance Oil Catch Cans or Oil Catch Can Kits will reduce this damage caused by Gasoline and Diesel Direct Injection Engine "blow-by". Our McNally Gen 2 Oil Catch Can provides continuous cleaning with every mile and in every driving condition for the life of your vehicle.

  • Maintain Fuel Efficiency
  • Coalescence Filtration
  • Dual Chambers
  • Internal Low Drag Check Valves

Understanding the Need for a Proper GDI Engine Oil Catch Can

Everyday 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. 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. 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.

McNally Gen 2 Oil Catch Can is a true oil PCV crankcase evacuation and separation system. 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.

Without a Oil Catch Can this Condition Is
Progressive and Exponentially Impairs Performance

  • Reduced horsepower and torque
  • Contaminated Catalytic Converter(s)
  • Reduced Catalytic Converter life requiring replacement runs +$2,000 each.
  • Fuel Mileage efficiency

The cost from having to do an Intake mechanical cleaning due to carbon build up 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. If the cleaning is not properly performed by a certified mechanic it is possible for corrosion and even worse may eventually force the purchase of new Catalytic Converter. The McNally Gen 2 Oil Catch Can takes out the problematic particles before they reach your engine.

Preventing costly mechanical repairs and engine damage to your vehicle requires additional modifications to your engine. Adding a McNally Gen 2 Oil Catch Can to the closed Original Equipment by Manufacturer (OEM) Positive Crankcase Ventilation (PCV) system is the first step to keeping money in your pocket rather than spending it on auto repair bills.

Understanding the Difference Between
Screen Filtration and Coalescence Filtration.

The screen filtration system is just that. You push a liquid (or gas) thru a screen to filter out any unwanted contaminants. When you are dealing with particulates such as "blow-by" that screen will eventually become blocked up. The McNally Gen 2 Oil Catch Can’s stainless steel coalescence filtration system provides an increased amount of surface for the particulates to attach themselves to BEFORE these harmful particulates get to your engine. Every engine and vehicle will vary in the amount and mixture of contaminants that are filtered. The best part is the McNally Universal Gen 2 Oil Catch Can is maintenance free. You only have to drain the Oil Catch Can with every oil change.

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 with time. The McNally Electronics Gen 2 Universal Oil Catch Can catches these harmful contaminants BEFORE the damage is done to your vehicle.

Best Can Ever!
These oil catch cans are one of the best on the market that I have tried! I purchased two other brands, that were either too small, or did not meet their expectations. But these McNally catch cans are very effective in collecting the excessive gas and oil, for my 2013 F150 ecoboost!

Catch can is exactly as described. Construction is solid using metal/aluminum parts and the machining is precise. I would recommend this product to anyone looking to buy one. Installed it on a 2014 f150 ecoboost and now waiting to see the results. Ordering and shipping was a breeze as well.

Great Performance! Installed on Chevy 5.3L L83 DI engine along with an oil change. I'm at 47% oil life left and my catch can already had to be emptied. The design on this is superior. Stay away from generics and I would always recommend getting a large capacity can. The only improvement I could recommend is to make it bigger! Avoid dirty valves with Direct Injection and install this can.

Catch Can
This is a quality product. It is too early to tell if it does what it claims as I have not really put enough miles on my F150 to check how much water and oil it catches, however it was fairly easy to install and every thing I see about the EcoBoost GDI engine this is needed to protect the intake valves and the engine

The McNally Gen 2 Oil Catch Can is really beautifully made. I fitted this unit to a 2015 Holden Commodore SV6 fitted with a 3.6 liter LFX engine. I folowed the instructions reffering to a 3.6 liter Cadillac CTS and everything worked out fine. The catch can was fitted on the LHS between the engine and radiator and has the appearance of an OEM part. I made my own custom bracket which supports the base as well as the top.
