Road Test Results – Baffled Oil Catch Can for 2024+ Mustang V8
We’re entering the fourteenth year of production for Ford’s 5.0L Coyote V8 engine, and in that time the Coyote has made a name for itself. It’s a powerful, throaty engine that’s been in the Mustang GT since the 2011 model year. Since its inception, the folks at Ford have managed to squeeze an extra 68 horsepower out of the Coyote with the new 2024 Mustang GT boasting 480 horsepower. Despite these gains, one issue the Coyote has had for years still persists—excessive blow-by.
What is Blow-by?
If you’re not familiar, blow-by is a result of high pressure on the top side of the piston pushing combustion gasses, as well as droplets of oil and fuel, past the piston rings and into the crankcase. To prevent excessive pressure in the crankcase, most modern vehicles extract blow-by via the PCV system and route it back into the intake. While most manufacturers add an air-oil separator to the PCV system, they often aren't as effective at removing oil as we might like. This leads to the problem of oil and contaminated fuel entering your intake system, potentially leading to engine knocking, power loss, and shortened engine life among many other issues.
Our baffled catch cans prevent the damaging air and oil blow-by from reaching your intake. With our catch can installed between the crankcase and the intake, oil and fuel vapors are separated from blow-by gasses with turbulators and baffles. Our catch can traps these contaminants while sending clean air through a filter to the intake.

Mishimoto’s Baffled Catch Can
Our engineers set out to design a baffled catch can for the 2024+ Ford Mustang V8 with a few goals in mind.
First and foremost, the most important goal was to ensure our design effectively collected and filtered blow-by. The second goal was to design the catch can as a direct fit for the 2024+ Mustang V8, ensuring easy installation and operation with no trimming or cutting required. We also wanted to make sure the catch can was easy to service and looked sharp in the engine bay.
To meet these goals, our first step was to incorporate our existing Mishimoto V2 Compact 2-Port Baffled Catch Can design. This road-proven and dependable design is made from 100-percent billet 6061 aluminum, featuring a 50-micron bronze filter and internal air diverter to improve oil separation.
Next, our engineers fabricated a custom two-piece bracket and measured for our fuel and oil-resistant hoses. Not only does the metal bracket offer sturdy dependability, but the two-piece design allows for easier servicing. The nitrile hoses feature excellent fuel and oil resistance, so they won't degrade over time like cheaper rubber hoses.
Road Test Results
As we expected, the latest version of the 5.0L Coyote V8 produced significant blow-by. Our engineer, Anthony, was surprised at how much blow-by was collected in such a small timeframe. After only 1,493.6 miles of driving, we measured 15mL of blow-by collected in our baffled catch can.
These results tell us two things. First, our baffled catch can successfully performed and met our goals. Second, the latest generation of 5.0L Coyote V8 engine is still suffering from excessive blow-by production, meaning it is a powerplant that greatly benefits from the addition of a catch can.
The Mustang we tested did not have high-mileage, ending our test with 6,558 miles on the odometer. If we were able to collect this much blow-by in a short amount of time on a low-mileage Mustang, imagine how much is reaching the intake over the lifespan of the engine.
