What to Look for Before Buying?
Well, going through the reviews will not be enough if you want to get a unit that will let you get the most out of your engine. For that, you will also have to keep some factors in mind. And, these are the ones that you should keep in mind before you decide to make a purchase:
Before you make a purchase, the first thing that you have to consider is the overall build quality. Even though most of the units will come with an aluminum body, there might be some other material.
And we would recommend you to stick with the aluminum ones only because they are exceptionally durable and will last for a long amount of time.
Alongside the build quality of the unit, you should also factor in the overall weight. If you get something that is not lightweight, you are going to add unnecessary heft to your vehicle, which is not ideal.
Most of the aluminum ones are generally lightweight and will add a minimal amount of weight to the car. So we would suggest you opt for those ones only.
Most of the catch cans have a general feature, which is to lower the number of contaminants from the intake to enhance the overall performance. However, some come with some extra features backed in. Such as the oil catch can with breather can filter out the air too. So if you are looking for additional functionalities, we would recommend going for those.
A proper seal of the body is an important factor in the case of oil catch cans. In that case, we would recommend you to opt for the ones that have TIG welding and comes with thick O-rings. Those will be able to make a proper seal and will not allow any oil leakage to occur while the can is functioning.
How to Make an Oil Catch Can?
If you do not like to spend some extra bucks to get an oil catch that can be installed in your car, you can make one by yourself. And we are going to simplify that process too. The steps that you have to follow are:
Step 1: Gather Necessary Materials
To begin with, you are going to have to gather some materials. The things that you are going to need are:
- An aluminum bottle, motorcycle air filter
- A section of rubber hose
- Steel fiber
- Mount for a car fire extinguisher
- Epoxy putty
- Copper or bronze fitting
- self-tapping screws, nuts, and bots
After getting all of this, you should be ready to begin the assembly process.
Step 2: Assemble the Parts
First, you will have to fit the hose section on the mouth of the aluminum container. Make sure you have a proper seal for that, or else you are going to have face leaking problems.
Then you will have to drill a hole into the container. The hole should be 2/3 from the bottom and to the top. This hole will have to be widened, and you can use a round file for that. After that, you will have to install copper or a brass fitting.
Next, you will have to apply epoxy putty to the base of the copper or brass fitting that you just installed. Then you will have to stuff the inside of the container with steel fiber, which will trap the oil and water droplets and also carbon deposits.
Lastly, you will have to use an extinguisher mount at the engine bay. You can use a rubber to make it hold on to the bay securely. And you can scavenge that from the inner tube of a punctured wheel.
Step 3: Install the Catch Can
You are going to need a couple of bolts, self-tapping screws, and nuts. Use them to connect the catch can to the valve cover. And for that, you will also need a rubber hose.
Moreover, you will have to factor in the movement of the engine, or else the fitting can disconnect or break while the engine moves. After you have connected the unit properly, you should have a working oil catch can in your vehicle.
Breather Tank vs. Catch Can
Even though a breather tank and a catch can sound like the same thing, they are not. In fact, each of the units has a separate functionality, and one can not replace the other. We are going to let you know what each of them is for.
The functionality of a breather is to relive the gas pressure and allow it to evaporate throughout the filter. It is just a cap that you have to install to the top of the valve cover. For sealing the intake properly, you will have to cap it to the intake line too.
However, there are some caveats with this unit. The breather might cause the engine to emit a smell from the raw fuel and oil. Alongside that, you will have to replace the unit every time it becomes full.
Oil Catch Can
As you know by now that oil catch cans are installed directly to the fuel intake of the engine. That means you will not have to fiddle around with the installation process as much you have to for a breather tank.
It will keep the engine bay clean and will be able to make the fuel vapors recycle into the engine efficiently. With that, it will not only emit the strong fuel smell that a breather usually emits.
Frequently Asked Questions
Why should I get an oil catch can?
Usually, in the cylinder and chamber dividers, you will notice there is no proper seal. Because of this, the pressure and the oil can outflow the cover area. And this outflow can cause carbon build-up, which an oil catch can mitigate.
Can an oil catch can increase the overall performance?
They can not directly increase the car's overall performance. However, having one of these in your vehicle will make sure that the engine is clean, which will make sure that it can perform optimally.
How often should I drain the oil catch can?
It will totally depend on the workload of the engine. However, we would recommend you to check the internal fluid level after every 500 miles of driving.
What is the benefit of having a dipstick in an oil catch can?
If the oil catch can has a built-in dipstick, you will be able to check the internal fluid level directly. Apart from that, you will also not have to dismount it to empty the fluid inside.
Does an oil catch can need a breather to work?
No, they will not require any breather to work optimally. However, if you require one that comes with a breather, you will be able to find one.
With that, we would like to wrap it up here by hoping that we were able to make choosing the best catch can easy for you. We wish you good luck and hope that you can get the most performance out of your engine without facing any deterioration.
