The Ultimate Buying Guide: Catching What Matters
Are you looking for a way to keep your engine cleaner and running smoother? A catch can might be just what you need! This handy device traps oil and gunk that can build up in your engine. Let’s dive into how to pick the best one for you.
What is a Catch Can?
A catch can, also called an oil catch can or PCV catch can, is a small container. It connects to your engine’s crankcase ventilation system. This system lets out gases that build up inside your engine. Without a catch can, these gases can carry oil mist and other contaminants back into your engine. This can make your engine parts dirty and less efficient. A catch can stops this by collecting the oily stuff before it gets back in.
Key Features to Look For
When you’re shopping for a catch can, keep these important features in mind:
- Capacity: How much gunk can it hold? Bigger is often better, especially if you drive a lot or in tough conditions. You won’t have to empty it as often.
- Baffling/Filtering: Does it have good internal parts to trap oil? Look for cans with internal baffles or filters. These help separate the oil from the air more effectively.
- Drainage: How easy is it to empty? Some cans have a drain valve at the bottom. This makes cleaning out the collected oil super simple. Others might require you to unscrew the can.
- Mounting Options: How will you install it? Check if it comes with brackets or clamps. Make sure it will fit easily in your engine bay.
- Hose Connections: Are the fittings secure? The hoses connect the catch can to your engine. Good quality fittings prevent leaks.
Important Materials
The materials used in a catch can affect its durability and performance.
- Aluminum: Many good catch cans are made from aluminum. This metal is strong and lightweight. It also doesn’t rust.
- Steel: Some less expensive options use steel. Steel is also strong, but it can rust over time if not protected.
- Hoses: Look for hoses made from oil-resistant rubber or silicone. These will last longer and won’t break down from engine heat or oil fumes.
Factors That Improve or Reduce Quality
Several things can make a catch can great or not so great.
- Good Quality:
- Solid Construction: A well-built can feels sturdy and has smooth edges.
- Effective Internal Design: Baffles and filters that really catch the oil are a big plus.
- Leak-Free Connections: Tight fittings mean no oil or fumes escape where they shouldn’t.
- Easy Maintenance: A simple drain valve makes keeping it clean a breeze.
- Poor Quality:
- Thin Metal: Cans made from thin, flimsy material might dent easily.
- Poor Sealing: If the lid or fittings don’t seal well, you’ll have leaks.
- No Internal Trapping: A simple empty can might not do much to catch oil.
- Difficult Draining: If it’s a hassle to empty, you might not do it as often as you should.
User Experience and Use Cases
People use catch cans for a few main reasons.
- Cleaner Engine: The biggest benefit is keeping your engine’s intake system cleaner. This means better airflow and more efficient combustion.
- Improved Performance: A cleaner engine can sometimes lead to a little boost in performance and fuel economy.
- Preventing Oil Consumption: By trapping oil mist, it can help reduce how much oil your engine burns.
- Tuning and Performance Cars: Enthusiasts often use catch cans on modified or high-performance engines. These engines can produce more blow-by gases.
- Everyday Driving: Even for regular cars, a catch can can help maintain engine health over time.
Emptying the catch can is usually the main task. How often you do it depends on your driving and the can’s size. Most users find it’s a simple task that takes just a few minutes.
