What does a crankcase vent filter do?

How do I know if my crankcase vent filter is bad?The crankcase ventilation system works by rerouting blow by gases back into the engine’s intake manifold to be consumed by the engine. The crankcase vent filter functions similarly to other filters.

How do I know if my crankcase vent filter is bad?

The crankcase vent filter works the same way as any other filter. When the crankcase ventilation filter needs servicing, it will usually display few symptoms that can alert the driver that attention is required.

  • oil leaks 
  • high idle 
  • decrease in engine performance 

If it has been a while since you inspected your crankcase vent filter, have it inspected by a professional mechanic to determine if it needs to be replaced.

Additionally, WIX offers a line of crankcase-breather filters that are purpose-built for today’s high-performance and high-demand automotive applications.
