The crankcase breather filter makes sure that only clean air enters your car's system. When this filter is clogged, it could eventually result in oil breakdown and sludge buildup. Replace your crankcase breather filter as soon as you notice the symptoms of damage.
What type of breather filter should be used?
Replace a damaged crankcase breather filter, unless you want to revamp the entire engine and spend more for repair. Replacement crankcase breather filters are relatively cheap. In fact, you won't have to spend more than 10 USD for each. If you're looking for a replacement, there are two main types:
- To-atmosphere crankcase breather filter: This type of crankcase breather filter comes in a traditional design. It can come with either a rubber or alloy neck that is installed to your engine's crankcase hose. Inside this is a crushed aluminium filtration material, which is resistant to petrochemical corrosion. Fumes from the crankcase are vented into the air. This makes the filter moderately easy to clean.
- Inline crankcase breather filter: This type of crankcase breather filter is considered a pipercross inline or "sealed unit". This type uses a washable reticulated-foam filter element that can be placed into your existing crankcase pipework. The inline crankcase filter is ideal in parts of the world where "venting to atmosphere" is not allowed. The filter element can be washed. This allows the filter to work properly all the time.
What are other things to consider when selecting a crankcase breather filter?
Before you purchase your brand-new replacement crankcase breather filter, you have to make sure that it comes with a complete set of installation instructions or a manual. By installing your crankcase breather filter on your own, you'll get to cut down costs and learn the basics of crankcase breather filter installation as well.
Crankcase breather filters are usually made from synthetic nanofibers and aluminum alloy with chrome coating. They also have wire-backed pleats that provide strength and filter longevity. Most crankcase breather filters can be cleaned easily, which makes them long lasting. They are cleaned in the same way as using either low-pressure shop air on the clean side or a vacuum on the dirty side. It is advisable to select only trusted names in the industry, so you won't be sorry you purchased the part in the first place.
