FAQ oil catch can

What is an Oil Catch Can?

 

During the combustion process, a certain amount of gas does not leave through the exhaust, rather it makes its way into the crankcase. The crankcase is equipped with a PCV valve which diverts the dirty air back to the intake system. An “oil catch can” sometimes referred to as a Catch Tank or Air/Oil Separator is a remarkable mechanical component that helps to separate oil from the dirty air. Once the air enters the catch can, it comes in contact with the baffles inside the can where the air condenses and separates into fuel, oil and other contaminants. All the contaminants fall to the bottom of the can while the clear air is sent back to the engine where it can be re-burned.

 

Although every gas-powered car experiences gas blowby which is the buildup of oil vapor in the intake and throttle body, but mostly high-performance engines suffer badly as their performance drops significantly. If you notice an oily residue in your intake system, it is time better to get an oil catch can.

 

Do Non-Turbo Vehicles need Oil Catch Can or is it Only Necessary for Turbocharged and Supercharged Engines?

 

Every vehicles experiences carbon buildup and blow-by production on the intake valves whether it is naturally aspirated, turbocharged or supercharged. However, in turbocharged and supercharged cars, this carbon and blow-by buildup is in huge quantity especially when the vehicle is under boost. This makes it necessary to install an oil catch can in order to ensure a smooth engine performance.

 

The modern direct injected engine gets dirtier much faster than the traditional multi point fuel injection systems because the fuel moves directly into the combustion chamber and no fuel are sprayed on the intake valves to keep them clean. As a result, dirt accumulates on the walls of the intake manifold and intake valves causing a disrupting performance. Installing an oil catch can on a non turbo and turbocharged engine prevent by collect oil and carbon sludge buildup to the intake system and maximizes the engine performance.

 

 

How Often Should I Drain My Oil Catch Can?

It depends on the driving condition, driving range, blow-by buildup and weather condition which determines how often you should drain the oil catch can. However, we typically suggest to drive 500 miles after installing a catch can then drain the oil and measure the amount of buildup. This will help you determine easily when to drain the can.

 

What are the Oil Catch Can Benefits?

The Oil Catch Can is necessary for vehicles with direct fuel injection engines as the valve rings do not perfectly seal between the piston and the cylinder walls. Due to this gap, pressure, as well as burnt oil, escapes into the valve cover area producing blowby. Blowby makes its way into the PCV line and breather where they are recycled back into the intake manifold reducing the octane level. Moreover, the blowby results in carbon deposits in the intake valve and the oil catch can help in reducing this deposit. This also ensures a long life of the engine as well as the oil as most contaminants are removed before they can get mixed with the engine oil. Also, the knock retard is eliminated due to the absence of contaminants resulting in a phenomenal performance as well as fuel economy.

 

What is the Purpose of a Stock PCV System?

PCV or Positive Crankcase Ventilation system is designed to circulate the fumes out from the engine crankcase. This helps to reduce the crankcase pressure which would otherwise result in oil leakage or damaged seals.

 

Difference Between Directly Bolt on Baffled Catch Kit VS Universal Baffled Catch Can?

Direct-fit catch can kits feature specific brackets and hoses for a bolt-in install. Come with everything that you need for the specific vehicles

Both bolt-on and universal catch can maintaining excellent octane level and reduce detonation. Moreover, baffled catch cans have an internal surface area where the oil mist condenses and separates.

 

What is the different closed loop vs vented catch can?

Vented catch can keeps the intake clean and prevents the buildup of blow-by while improving the octane level. However, during long drives and a higher boost, vented catch can produce a bad smell of burnt oil.

On the other hand, the Closed Loop catch can do not produce any smell but it allows some oil to get mixed with the gas in the fuel chamber. However, the amount is very minimal so it doesn’t cause any problem.

 

Single Vs Dual Oil Catch can

Single Valve Catch Can – This particular catch can is tailor-made for naturally aspirated motors. In other words, it is perfect for those of you who are not focused on performance.
Dual Valve Catch Can – The dual valve catch can, on the other hand is designed to fit all types of engines may they be naturally aspirated engines or forced induction engines. This catch can is forged for vehicles that are being built for performance. Performance vehicles that have superchargers or turbos installed can earn more advantages from a catch can as the can catches unwanted oil vapor and stops it from going into the engine manifold.


Why Dual Oil Catch can and how does it work?

The Dual Catch Can Kit has both PCV and CCV side covered. This way the air is purified when it exits and enters the system. The catch can absorb the blow by, oil vapor and other pollutants that come through the PCV side and CCV side


Why V3.3 Oil catch can and how does it works?

The engine works by turning the intake manifold as the source of vacuum, which sucks all the blow-by back to the intake system. However, when the throttle is pressed (WOT), the intake manifold stops building the vacuum pressure and during this time, damaging compounds like blow-by water, carbon, ash, and sulfuric acid can go through and mix with the oil, damaging the engine in the process. The intake manifold is before the throttle and the catch can only work when in idle.
The V3.3 oil catch can work if the vehicle is in idle or in acceleration and is more efficient than a single oil catch can. The V3.3 catch cans are used as an additional suction source of help to the blow-by problem by Adding additional vacuum location just in front or upstream of the throttle body or TB inlet and we utilize one-way inline check valves that select the best possible suction source when the full throttle is open.


which oil catch can should i get ?

If you are not focused on a performance engine and not going to run the engine hard, go WOT, or track. The single oil catch can or dual oil catch can is fine. . The V3.3 is practically better because it provides the best results based on the strongest suction source at the time and generated suction just in front of the upstream of the throttle body or TB inlet.
