Genuine Mazda Oil Separator for Mazda 3, Mazda 6, Mazda CX-5 2.0 2015-2021 PE0113570

Genuine Mazda oil separator for Mazda 3, Mazda 6, Mazda CX-5 2.0 2015-2021, part number PE0113570 is an important component of the crankcase ventilation system (PCV), designed to separate oil particles mixed in crankcase vapors before the gas is returned to the intake tract for combustion. This helps limit oil buildup in the intake pipe, intake manifold and combustion chamber, contributing to lower emissions, engine protection and stable operating performance.

On Mazda 3, Mazda 6 and Mazda CX-5 with the 2.0 Skyactiv-G engine from 2015-2021, the oil separator works in sync with the PCV valve, valve cover, intake manifold, throttle body, crankcase ventilation hoses and engine ECU. When the oil separator works properly, oil vapor is effectively separated before returning to the combustion chamber, helping the engine run smoothly, reduce deposits in the intake system and limit lubricant consumption.

PE0113570 is an original Mazda part manufactured to high quality standards with a heat-resistant engineered plastic body, optimized oil-separation chambers and an integrated PCV valve system (depending on version). The correct-spec design provides efficient oil separation, withstands temperature and pressure in the engine bay, and installs accurately on compatible models without modification.

After a period of use, the oil separator may become clogged with oil residue, the ventilation passage may be blocked, or the PCV valve may fail, causing abnormal crankcase pressure. In that case, the vehicle may show oil consumption, unstable idling, a Check Engine light, oil leaks through seals, or heavy oil buildup in the intake system. If not replaced in time, engine performance will decline and the risk of carbon buildup in the intake will increase.

PE0113570 is manufactured to Mazda original equipment standards, ensuring effective oil separation, high durability and full compatibility for Mazda 3, Mazda 6 and Mazda CX-5 with the 2.0 Skyactiv-G engine.
