If you buy something through a link in our posts, we may get a small share of the sale.

There is a lot going on in the internal combustion engine of your vehicle. One of which is the build-up of pressure in the crankcase. As the pistons inside the engines move continuously, they exert a huge volume of air in and out. Blow-by is formed due to this buildup of pressure.

In the crankcase of the engine, this pressure starts to increase rapidly. If that pressure is not released, it causes a lot of harm to the engines. This pressure needs to escape. The gas that creates this pressure is a mixture of air, oil, and other contaminants.

Catch cans work by collecting contaminants which would otherwise form carbon deposits in the intake valves. By installing a the best oil catch can, you will increase the longevity of the engines by keeping it from being damaged!

Benefits of Using Oil Catch Can

If you own a modded vehicle that has an internal combustion engine, then installing a catch tank will keep your vehicle free from engine related issues, and frequent repairs.

An oil catch can in your vehicle favors your car in two ways.

1. Prevent Sludge And Carbon Deposits From Forming

Accumulation of residual carbon and sludge creates issues in your vehicle’s engine and intake system. The impurities from the blow-by air tend to build up on turbochargers, intake manifold, piping, and other parts.

The device allows you to capture the oil contaminant from the pressurized air. The air will then travel to your car’s intake manifold and so, no deposits form on your intake valve.

2. Increases Engine Performance

The buildup of deposits may heavily reduce the power produced by the engines. Issues such as knocking, pre-ignition, and low fuel economy occur due to clogging of the injectors. An oil catch can prevent these problems to occur and increase the performance of your car.

Things To Consider Before Buying The Best Oil Catch Can

If you are considering getting an oil catch can for your vehicle, there are a couple of things you must know. Not all the catch can you see are created equally. You may just buy one and it doesn’t work the way you thought it would.

Here are the factors you need to consider before purchasing a catch can.

1. Know What You Are Getting

You have to be extra careful when purchasing catch cans, especially from online marketplaces. Scams in the aftermarket parts world are very common.

One of the biggest scams in purchasing the tank is that there are no filter components inside. They can usually come with a filter that separates the contaminants. Make sure that all the components are mentioned by the supplier on their product page.

2. Pricing

Oil reservoirs come at multiple price ranges. The inexpensive one usually doesn’t have a baffle system. They have steel wool that divides the contaminant from the oil-air mixture. A baffle system is generally better at separating the oil.

3. Appearances

This is an important factor to consider since it is an aftermarket device. Most catch cans are made with sturdy aluminum alloys, which gives the tank a sleek look. The device comes in various colors, to match the theme of your vehicle. You can select one that stands out or blends in perfectly.

4. Features

The more features, the better! Apart from the baffle system that filters the oil from the oil-air mix, there are other components that make the device worth purchasing.

This includes a dipstick that allows you to monitor the level of oil that is captured, drain valves that can empty the can without opening the entire thing and so on.

Why Don’t Some Cars Come With Oil Catch Cans?

Catch cans are found in most performance cars. Catch cans are usually installed by the owners themselves. This brings a good question.  Why don’t manufacturers place cans on their cars?

Gasoline direct injection or GDI engines have great benefits when an oil catch tank is installed. There is a good reason as to why cans manufacturers do not place it on their vehicles.

The PCV system of your vehicle functions by drawing the pressure from the crankcase. It also sucks out moisture that has tiny oil particles that are in the intake charge.  The oil deposits cause performance loss, reduced combustion, low fuel efficiency, and other engine component problems. The repairs can be expensive.

You will find that a lot of vehicle owners mismanage oil changes. Oftentimes, owners forget when their cars need maintenance. The contaminants are captured from blow-by gases. The deposits form doesn’t cause problems to the vehicle immediately. It is important to know that the damage happens over time.

Also, the manufacturer doesn’t want you to stick to the same car. Manyas owners eventually change their car and the manufacturers want you to purchase the vehicles from them.

Oil Catch Can Take Care Tips

Oil catch cans are durable devices that don’t require much maintenance. You still have to keep the can clean and get rid of the oil deposits on a regular basis. Here are some tips you can use to increase the longevity of cans:

1. Drain The Tank Frequently

The type and volume of contaminants collected depend on various factors.

It depends on the driving conditions, miles driven, and condition of the climate. The most appropriate time to deplete the oil is after every 500 miles or so. Keep a note of the volume collected so you know when to drain the tank next time.

2. Keep The Oil Catch Cans Clean

The engine parts and the outer surfaces usually become soiled with grease and other types of dirt. The oil catch can will too.

The best way to clean the engine and the cans is by using a degreaser. This will effectively remove dirt and grease without harming the oil catch cans.

3. Clear Any Clogs That Forms

You want oil catch cans to function effectively. Clogs don’t just form on the engine components. They can build up on oil catch cans as well.

To clear any clogs, simply start the engine and when it is in idle mode, open the drain valve of the can. This will release any vacuum that developed in the oil catch cans.

A second way to unclog the can is to remove the oil cap. Then you need to open the drain valve. This will allow the air and unclog the catch can.

Frequently Asked Questions

1. Do Oil Catch Cans Actually Work?

Yes, oil catch cans actually do prevent contaminants from entering the intake manifold. The pressurized gases from the crankcase enter the oil catch cans before the intake manifold. This is where tiny droplets of oil are collected.

It is true that not all the contaminants can be collected, and some eventually do enter the intake manifold. Oil catch cans collect the majority of the oil, which would have coated the intake manifold if not collected.

2. What Is Inside an Oil Catch Can?

Oil catch cans are designed with the baffling on the inside that traps oil and vapor on the bottom side of the reservoir. The baffling system prevents the oil from going back up and then traveling over to your intake.

Some expensive oil catch cans have a micron bronze filter that also prevents the oil or contaminants from going back to the intake. There is also a dipstick so you check the level of contaminants in the oil that you have caught within the catch can

3. Where Should I Mount My Oil Catch Can?

The Oil-air separator is mounted in your vehicle’s engine compartment. The most appropriate place to mount a catch can kit is on the hook that holds the thermostat housing.

The reason why mounting the oil-air separator in this region is a great idea, is because it will allow you to drain the collected oil from the drain valve of the oil-air separator. This region also provides a clear pathway for the hoses to go along with the vents.

4. How Hard Is It to Install an Oil Catch Can?

One of the most notable things about a catch can is that it can be installed very easily. It is a simple modification that comes with great benefits. You don’t have to tune the device after installation. You can get the can installed in as little as 5 minutes.

If you don’t have prior experience in installing the device, then it’s better if you let the experts do it. You need to route the hose in a specific way, and the fittings need to be firmly attached. The use of management tools such as ties may also be required.

5. Oil Catch Can vs Breather Tank

The main purpose of a breather tank is to prevent pressure build-up. By preventing the pressure build-up, a breather tank will promote the engine’s health.

It will also free up a considerable amount of horsepower. It does this by preventing the creation of positive pressure. It allows the pistons and rods inside the engine to move more freely.

This way, the breather allows the engine to work more efficiently. Breather tanks are necessary for high boost/horsepower induction applications.

A catch can simply capture the deposits by cooling the hot and pressurized gas. The gas forms liquid droplets, which are collected in the tank.

6. Who Makes the Oil Catch Can?

There are several manufacturers that make fantastic oil catch cans. But not all oil catch cans are created equally.  Whatever option you select will work fine. Oil catch cans are all designed to increase the longevity of the engine.

If we had to name any particular catch tank, we’d choose the one from Dewhel. The catch can have all the features you need. Their products are well received by customers and provide satisfying performance.

Final Words

Installing a catch can give you that race car noises or a massive boost in performance. It is just a simple modification that will increase the longevity of the engines.

It is true that you don’t necessarily need to have this device. Your vehicle can function easily with having a catch can. This is the reason car manufacturers don’t include them.

The best oil catch can simply separates the contaminated oil from the air-oil mixture. The workings of the device might sound pretty simple, but it is very effective. It can also help you avoid costly engine repairs and save you a ton of money.

We hope you get the best oil catch can for your vehicle that will keep your engines running smoothly for years to come. Take care!
