The components that make up your automobile are made from some tough stuff, but over time, they will have to be replaced. The crankcase breather in your car's engine is one of them. Typically, a crankcase breather should be replaced once every 12,000 miles along with the PCV valve, but if it becomes extremely clogged with oil and dirt, it should be replaced immediately. Luckily, crankcase breathers are not that hard to install in the engine and are easy to find in the market. In this guide, we are going to show you some pointers on buying a replacement crankcase breather for your vehicle.
Types of breather
There are different types of crankcase breather on the market. Some of these include:
- Alloy base
to atmospherebreather: This crankcase breather is fitted with a 13mm diameter neck leading to a crushed aluminum filtration medium that's resistant to most chemicals and one that absorbs moisture. Some models also come with either polished silver or anodized filter caps.
- Rubber base
to atmospherebreather: This is similar to the alloy base
to atmospherebreather except that, as its name implies, it has a rubber base. It also comes in more varied neck diameters, ranging from 13mm to 19mm.
- Alloy base sealed inline breather: This breather comes with a reticulated foam filter, which provides good filtration capabilities and high air intake. The filter can also be reusable and washed regularly. In addition, the breather also comes with a 13mm inlet and outlet neck for the air to come through.
Make sure that you get the right crankcase breather for your car. Installing the wrong kind of breather in your car may lead to oil dripping out of the valve cover gaskets.
In addition to original equipment manufacturer (OEM) replacement breathers, there are also aftermarket crankcase breathers that you can purchase. This type of breather is not made to follow the exact same specifications set by the manufacturer (as with OEM crankcase breather) but instead has its own unique features that may increase the efficiency of the engine or make it last longer than a factory breather. Some aftermarket breathers, for example, are made from lighter but more durable spun aluminum alloy, while some are fitted with special
media traps that collect more contaminants. However, these aftermarket components are not guaranteed to perform or last in a similar fashion as OEM breathers.
