A catch can keeps oil from ending up where it isn’t supposed to be and prevents the problems that come along with that. They can extend the life of your vehicle substantially.
What Is A Catch Can?
Catch cans, also called oil catch cans, prevent oil and other contaminants from building up in your engine’s intake manifold. We can install catch cans for a variety of different 4×4 makes and models.
What You Need to Know About Catch Can Installation
These devices can help most vehicles, but especially those that have direct injection engines.
Direct injection engines, like those found in 4x4s, inject fuel directly into the cylinder, which means the fuel doesn’t pass through the intake manifold to act as a cleanser as it does in port-injected engines. That means that there’s nothing preventing the oil from building up in your system, hence the need for a catch can.
The catch can plugs into the hose that runs from the top of your engine’s crankcase to the intake manifold. The hose relieves pressure in the crankcase, but it also allows oil into the intake manifold.
It’s positioned there so it can filter out all of the things that don’t need to be in your intake manifold or engine. Our mechanics can install the device quickly so you’ll be back on the road sooner.
Yes, there are universal oil catch can kits available that will work on most vehicles. Unless you have experience working on cars, it’s still advisable to take your car to a professional to have a catch can installed.
While it can be helpful in all vehicles, this device is extra important if you have a direct injection vehicle. Common vehicles that have these include some 4x4s, Hyundais, Kias, and Subarus, among others.
Without a filter to prevent debris from building up in your system, you could be at risk for engine issues. A common problem that results from oil buildup is for your engine to develop a “cough.” This is due to the airflow being blocked, which prevents the cylinder from fully igniting.
When making a case for getting an oil catch can, the benefits have to be mentioned. With that in mind, let’s go over them.
- The device prevents oil from clogging your intake manifold.
- It can increase the lifespan of your vehicle’s engine.
- Catch cans improve your vehicle’s fuel usage.
How Often Should A Catch Can Be Drained?
The general recommendation is that a catch can be emptied every time you get an oil change. That means you should be emptying it roughly every six months or 5,000 kilometres.
Keep in mind that every vehicle is different. It’s a good idea to check the catch can regularly until you’re able to establish how often it needs to be emptied to accommodate your vehicle.
Does A Catch Can Filter Need To Be Changed?
Yes, a catch can filter should be replaced from time to time. Unlike an oil change, there’s no set timeframe for when this should be done. Not all catch cans even have filters, and the ones that do can come with different recommendations.
It’s a good idea to ask your installer if there is a filter and how often they recommend changing it. They’ll be able to give you more information about your particular device and advise you on whether or not you can replace it yourself.

Catch Can Installation FAQ
Are our catch cans illegal?
Catch cans are designed to separate the fluid and mist from the air that makes its way through and catch it in the bottom of the unit, and they sit between the crankcase and the intake system. Your engine may cake up with oily carbon deposits without a catch can, and if not cleaned, you may suffer poor fuel economy and loss of power. Catch cans are entirely legal, and in some cases, they come as a standard like in some well-designed diesel.
Is it worth installing one on my 4x4?
There is no reason why you should not install a good quality catch can. This is the only legal way to keep your intake manifold clean and your car’s EGR working. In the long term, installing a catch can help you maintain power, good fuel economy, and reliability. If you are not proactive in maintaining clean piston rings and decarbonizing your engine, a catch can is recommended to help prevent some problems.
The main function of a catch can is to catch excessive amounts of oil that may be present in the intake system before preventing it from entering the cylinders. However, make sure you buy a quality catch can if you decide that good insurance is worth the expense.
Does your 4x4 need a tune after installing a catch can?
You do not require an aftermarket tune after installing a catch can. This is to say, re-tune after installing a catch can is not necessary. Vented or not, there are zero reasons to re-tune your car for a catch can. This is the beauty of installation; it is a straightforward modification.
However, you do not have to re-tune it if you have a tune. You will only need five minutes to install it. Installation only takes a few minutes from opening to closing the hood and is as easy as reconnecting and disconnecting a hose.
