The breather element allows air coming into the crankcase to be filtered. Most vehicles are equipped with both a PCV valve and a breather element. Over time, and as the PCV filter gets dirtier, the breather element gets clogged or damaged and can lead to engine damage. Oil leaks and excessive exhaust smoke are both signs your crankcase breather may be clogged. Over time, this can cause damage to piston rings and seals, and cause poor overall performance. Poor engine performance or oil leaks are also possible signs your PCV valve is failing. If the PCV valve is in working order, the breather element may need to be replaced. O'Reilly Auto Parts carries PCV parts for most vehicles, including a PCV valve and breather elements for a complete repair.
