Do I Need a Catch Can on My Silverado

As most truck owners know, the Silverado is a workhorse. It’s tough, it’s durable, and it can handle just about anything you throw at it. But one thing it can’t handle is oil buildup in the engine.

That’s where a catch can comes in. A catch can is a small container that attaches to the engine and catches excess oil before it has a chance to build up and cause problems.

A catch can is a small container that is installed in between the engine and crankcase of an internal combustion engine. The purpose of a catch can is to collect oil, fuel, and water vapor that would otherwise be lost through the engine’s PCV (positive crankcase ventilation) system. Over time, these fluids can build up and cause issues such as decreased performance, increased emissions, and oil leaks.

A catch can will help to prolong the life of your engine by keeping these fluids out of the combustion chamber. If you drive your Silverado regularly, or if you live in a dusty or dirty environment, then installing a catch can is highly recommended.

Best Catch Can for 6.2 Silverado

If you’re looking for the best catch can for your 6.2 Silverado, look no further than the Moroso Billet Catch Can. This catch can is designed to work with all Silverados equipped with the 6.2L V8 engine, and it’s crafted from high-quality billet aluminum for superior durability. The Moroso Billet Catch Can features a unique baffle design that separates oil vapor from air, and it has an internal filter that captures oil vapors and prevents them from entering the engine.

This catch can also includes a drain plug for easy maintenance, and it’s available in either a polished or black anodized finish.

Does My Engine Need a Catch Can?

If you have an engine, chances are you need a catch can. Here’s why: engines produce a lot of blow-by. Blow-by is when hot gases and oil escape past the piston rings and into the crankcase.

These hot gases contain water vapor and oil vapors. Over time, this moisture condenses on the cool surfaces inside the crankcase (like the cylinder walls). This causes rust and corrosion, which can lead to engine failure.

A catch can separates these blow-by vapors from the air inside the crankcase so they can’t cause damage. It also collects any oil that gets blown by, so it doesn’t end up in your intake manifold or clogging up your PCV system. That way, only clean air goes back into your engine.

So if you want to protect your engine (and who doesn’t?), get yourself a catch can.

What is a Catch Can on a Chevy Silverado?

A catch can is a device that is installed in an engine to catch and store oil and other fluids that may leak from the engine. The catch can is connected to the engine’s PCV system and prevents these fluids from entering the intake manifold where they can cause problems.

How Important is an Oil Catch Can?

An oil catch can is designed to stop oil from entering the engine from the crankcase ventilation system. It does this by collecting oil mist and vapors before they can reach the engine. The can then drains these fluids away so that they don’t enter and contaminate the engine.

Most engines are now fitted with an oil catch can as standard, but some older models may not have one. If your car doesn’t have a catch can, it’s worth considering fitting one as it could prolong the life of your engine. If you do a lot of short journeys or drive in stop-start traffic, an oil catch can is particularly important as these driving conditions produce more oil vapors than normal driving.

Oil vapors can condense on cold surfaces such as the intake manifold and valves, leading to deposits forming which can affect engine performance. So in summary, an oil catch can is a worthwhile addition to any car as it helps to keep the engine clean and running smoothly.

Can a Catch Can Cause Problems?

A catch can is a device that is used to collect fluids as they are released from an engine. The catch can is typically mounted on the firewall or fender and has a series of small holes drilled into it that allow the fluid to be collected and then drained away. While a catch can will not cause any problems if installed correctly, there are a few things that can go wrong.

If the catch can is not vented properly, pressure can build up inside of it and cause the engine to run leaner than normal. This can lead to engine damage over time. Additionally, if the catch can is not installed in the correct location, it may not be able to properly collect all of the fluid being released from the engine, which could lead to leaks.


If you own a Silverado, the question of whether or not you need a catch can is one that may have come up. A catch can is designed to prevent oil from entering the engine, and it does this by catching any oil that may be expelled from the PCV system. Many people believe that a catch can is unnecessary on a Silverado, but there are actually quite a few benefits to using one.

One benefit of using a catch can on your Silverado is that it will help to extend the life of your engine. Oil that enters the engine can cause all sorts of problems, and over time, this can lead to serious damage. By preventing oil from entering the engine, you can help to ensure that it lasts for many years to come.

Another benefit of using a catch can on your Silverado is that it will improve fuel economy. When oil enters the engine, it creates friction and resistance which causes the engine to work harder and use more fuel. Bycatch catching any oil before it has a chance to enter the engine, you can improve your truck’s fuel economy by as much as 5%.

So, if you’re wondering whether or not you need a catch can on your Silverado, the answer is yes! Not only will it help to prolong the life of your engine, but it will also improve fuel economy.
