Genuine 1271988 Engine Oil Separator PCV Breather Box

The Genuine 1271988 Engine Oil Separator is a factory OEM positive crankcase ventilation (PCV) component designed to maintain proper crankcase pressure and prevent oil contamination in the intake system. This oil trap assembly separates oil mist and vapor from blow-by gases before they are recirculated back into the engine's intake manifold, protecting engine performance and longevity.

Key Features:

• Factory Genuine OEM quality part manufactured to strict specifications
• Separates oil vapor from crankcase gases to prevent oil consumption and intake contamination
• Essential component of the crankcase ventilation system
• Helps prevent oil leaks, excessive smoke, and rough running conditions
• Direct replacement for worn or failed oil separator assemblies
• Also known as PCV breather box or oil trap

When this component fails, symptoms may include oil leaking from seals, white smoke from the exhaust, rough idle, or engine stalling. The oil separator works by trapping oil droplets from crankcase gases through internal baffles and filters, allowing cleaned air to pass through while returning separated oil back to the engine. Replacing a faulty oil separator restores proper crankcase ventilation and prevents costly engine damage caused by excessive oil consumption or contaminated intake systems.
