The oil catch can is also called the oil catch tank. This is a simple device that can be installed in the crankcase/cam ventilation system of a vehicle. Oil catch can reduce oil vapor, which is recirculated to the engine’s air intake.
They prevent contaminants and oil from accumulating in the intake manifold. Catch cans work by collecting contaminants which would otherwise form carbon deposits in the intake valves. By installing an oil catch can, you will increase the longevity of the engines by keeping it from being damaged.
Simply put, the oil catch can is just an additional filter, depending on the fact that oil is heavier than air to do its work. The equipment usually contains steel wool or a baffle system to separate the oil from the air. Then, the oil will fall to the bottom of the jar until it is cleaned. Even on budget, it can prevent oil from causing serious damage to the cylinder.
Oil Catch Can Benefits
- Prevent Sludge And Carbon Deposits From Forming
The accumulation of residual carbon and sludge can cause problems in the vehicle’s engine and intake system. The impurities in the blow-by gas tend to accumulate on the turbocharger, intake manifold, pipes and other parts.
This device allows you to capture oil from compressed air. Then, the air will flow to the car’s intake manifold, so no deposits will form on the intake valve.
- Improve engine performance
The accumulation of deposits can severely reduce the power produced by the engine. As the injector is blocked, problems such as knocking, pre-ignition and low fuel economy will occur. Oil accumulation can prevent these problems and improve the performance of the car.
Your engine is volatile. It is full of fuel, hot oil, a lot of forced air, and a lot of moving metal parts. All these work together to produce combustion. If you don’t know what burning is, it’s basically a series of explosions.
When the combustion process occurs, most of the compressed gas will be discharged through the exhaust gas. Leave some residue to make it enter the crankcase. This is called a leak.
A spare crankshaft ventilation system has been installed to prevent the accumulation of mist. Dirty air is transferred inside the valve. Using the oil catch tank, you can effectively separate the air from the oil. The filter returns the oil-free air to the engine, so it can continue to supply fuel to the vehicle.
The oil catch tank has been installed to the ventilation system of the crankcase. You place it between the intake system and the vent. When vapor passes through the tank, oil droplets, water vapor and unburned fuel will condense. This caused them to sink into the tank. This process makes them never reach your intake and prevents negative effects.
The best oil catch can have an internal filter. This may be Brillo type or fine metal mesh. This medium will create a larger area, giving these vapors a chance to condense. You will need to drain the excess oil that has accumulated over time, but this is a simple process, just open the drain plug.
In a typical four-stroke engine, the piston goes up and down four times per cycle. When it descends for the first time, the intake valve opens to create a vacuum. This process allows cooler, rich air to enter the combustion.
At the same time, fuel enters the cylinder. Then, the intake valve closes and the piston rises toward the top of the cylinder. Compression creates pressure inside the cylinder.
The pressure becomes so high that a small amount of air escapes through the piston and ring. Air enters the crankcase. Again, this is called a leak. As the RPM increases, the number of leakage will increase. If your engine has more cylinders, you can also expect more blowby.
It should be noted that not all air will escape, otherwise we will never burn. Only a small part.
The crank itself rotates in an oil pan full of oil (obviously). Although this keeps all components lubricated, ventilation must be maintained so that pressure does not build up inside the crankcase. If accumulation occurs, you will face unbearable failure. In turn, this caused a lot of oil to gush out on the street.
The pressure from the crankcase will return through the intake port, not just the air. It will also contain oil. This will pass through your intercooler and then back to the combustion chamber. Along the way, the oil will cover all parts of the intake manifold, valves, booster hoses and intercooler. Because of the high temperature, the oil solidifies onto the valves.
So-what will happen next?
The intake valves get caked with oil. In engines with port injection, this is not a problem because the gas is introduced before the combustion chamber. This allows it to flow through the intake valves. This action can actually clear the valve and prevent oil from caking.
In direct injection engines, agglomeration on the oil can cause many symptoms. These include:
- Reduce fuel economy
- Power loss
We know that automakers will not install oil catch tanks in factories.
We can solve the problem by placing the oil catch tank after the PVC and before the intercooler. This allows the pure air mixture to enter the intake valve and intercooler. This also means that you do not have to worry about oil caking and performance degradation.
Oil accumulation will greatly increase your strength or make an offensive sound. Therefore, many people who modify vehicles have overlooked this essential equipment. If they take the time to install the engine, they will find that the engine usually runs at maximum power and is worth the extra effort.

5 Best Oil Catch Can
When you are ready to find the best oil catch tank, there are a few things you need to know first. Not every catch tank is the same. In fact, if you are not careful, you may buy directly rubbish goods.
The biggest scam is to buy oil catch tanks with nothing in it. It should come with parts such as filter media and hoses. It should not be an empty can.
Even if you buy one with a hose attached, it may not reach the quality level you expect. In fact, many of them cannot withstand the vacuum pressure or high temperature of the engine compartment. It may melt or collapse, which is a disaster. If you feel that the hose is somewhat fragile, we strongly recommend that you purchase another after-sale hose.

Q: Oil Catch Can VS Breather Tank
A: The main purpose of the breather tank is to prevent pressure buildup. By preventing pressure buildup, the breather tank will promote the health of the engine.
It will also release a lot of horsepower. It does this by preventing positive pressure. It allows the pistons and rods in the engine to move more freely.
In this way, the breather allows the engine to work more efficiently. For high pressurization/horsepower induction applications, a breather tank must be used.
The catch can simply catch the deposits by cooling the high temperature and pressurized gas. The gas forms liquid droplets, which are collected in a tank.
