Your Guide to Catch Cans: Keeping Your Engine Clean
What is a Catch Can?
A catch can, also known as an oil catch can or PCV catch can, is a small device that helps keep your engine cleaner. It works by catching oil and moisture that can build up in your engine’s crankcase. This stuff can make your engine work less efficiently and even cause problems over time.
Why Do You Need a Catch Can?
Engines create a lot of pressure and gasses inside. Some of these gasses can get past the piston rings. These blow-by gasses can carry oil mist and water vapor. Without a catch can, these can go back into your engine’s air intake system. This oil can coat parts, reduce performance, and even cause damage.
Key Features to Look For
1. Size and Capacity
Catch cans come in different sizes. A larger catch can holds more oil before it needs to be emptied. For daily driving, a medium-sized can is often enough. If you have a high-performance car or drive in tough conditions, a bigger one might be better.
2. Internal Baffling and Filtration
Good catch cans have special insides. These insides, called baffles, help separate the oil from the air. They might also have a filter. These features make the catch can work better at trapping the oil and moisture.
3. Ease of Draining and Mounting
You’ll need to empty the catch can sometimes. Look for one that’s easy to drain. A valve at the bottom makes this simple. Also, think about how you’ll mount it. Some come with brackets, making installation easier.
4. Durability and Build Quality
A well-made catch can will last longer. Check the materials it’s made from. It should feel solid and strong.
Important Materials
Aluminum and Stainless Steel
Many good catch cans are made of aluminum. Aluminum is light and doesn’t rust. Some are made of stainless steel, which is very strong and resistant to corrosion. These materials help the catch can last a long time.
Plastics
Some cheaper catch cans might use plastic. While plastic can work, it might not be as strong or last as long as metal. High-quality plastics are better, but metal is usually preferred for durability.
Factors That Improve or Reduce Quality
Improved Quality
- Good Baffling: This is key to trapping oil effectively.
- Quality Seals: Prevents leaks and ensures the system works right.
- Sturdy Construction: Means it won’t break or leak easily.
- Easy to Maintain: Simple draining and cleaning makes life easier.
Reduced Quality
- Poorly Designed Baffles: Lets oil pass through.
- Cheap Seals: Can lead to leaks and loss of pressure.
- Thin or Weak Materials: May crack or corrode.
- Difficult to Service: Makes maintenance a hassle.
User Experience and Use Cases
For Daily Drivers
Even for everyday cars, a catch can helps keep the engine intake clean. This can lead to better fuel economy and a smoother running engine. You’ll notice less gunk building up on your intake valves.
For Performance Enthusiasts
If you have a turbocharged or supercharged engine, a catch can is almost a must. These engines produce more blow-by gasses. A catch can protects these high-performance parts from oil contamination.
For Older Vehicles
Older engines can sometimes have more blow-by. A catch can can help manage this and keep them running better for longer.
Overall, a catch can is a smart upgrade for many vehicles. It’s a simple way to protect your engine and keep it performing at its best.

Q: How does a catch can improve a car’s performance?
A: By preventing oil mist from coating intake valves and sensors, a catch can helps maintain optimal airflow and combustion. This can lead to better fuel efficiency and consistent engine performance.
Q: Is a catch can necessary for all cars?
A: While not strictly necessary for every car, a catch can is highly recommended for turbocharged or high-performance engines. It’s also beneficial for older vehicles that might have more blow-by gasses.
