Everything you need to know about oil catch cans


This time we will discuss Oil Catch Cans. Whats the use? How to install? Basically everything you need to know to find the best setup for your car.

How does an oil catch can work?
With most modern cars the carter is ventilated by one or more fittings from the valve cover to the intake. because of this a lot of oil will enter the intake channel which has negative consequences for the power of your car and can result in a sticky trottle. You can fix this by installing an oil catch can. This will catch the oil (surprisingly) and keeps the intake clean.

How to install an oil catch can?
Installation is pretty easy. Install an oil catch can in such a way that the hoses can be installed on the valve cover. Other fittings on the intake system can be plugged off. Just pay attention that you take some high quality hoses that are not thinner than the plugs on the valve cover. The best option is to take -AN fittingen, as there is no chance that these will pop off. Something that will sooner happen with regular hoses and hose clamps.



An oil catch can can be best placed at the front of the car, as this way the air from driving will cool the oil, so there is less oil fumes in the oil catch can.
Can you improve an oil catch can?
Yes, there are several ways to improve an oil catch can. for example you can put a heat sink in the oil catch can, therefore the condensation surface will be bigger. You can also put some steel wool at the bottom of the oil catch can, so the it will catch the fumes sooner. You can also put a breather filter on the catch can but make sure that there will be some baffles between the filter and the hoses on the valve cover. This because otherwise the oil fumes will be dumped into the engine bay right away.
Are there other options instead of an oil catch can?
Yes, you can also take an evac system. An evac system is actually a one way valve that goes from the valve cover to the exhaust. This way the fumes will be directly blown out to the exhaust system. This has no downsides for the APK as thik kit will only work at certain revs. You should also need some heat resistant hoses, as the exhaust can be pretty hot.
