Bentley Continental GT GTC Flying Spur 4.0T Oil Separator PCV Crankcase Breather 079103542E

4.0T Oil Separator / PCV Crankcase Breather for Bentley

Restore correct crankcase ventilation on compatible Bentley 4.0T models with a replacement oil separator assembly. Reference part number 079103542E, this unit manages crankcase vapour flow while separating oil mist before gases are routed back into the intake system.

Designed for 4.0T Engine Breathing Control

The oil separator is a key component in the positive crankcase ventilation system. Internal diaphragm or separator wear can contribute to unstable crankcase pressure, oil consumption, intake contamination, whistling noises or drivability faults. Replacing the complete assembly helps restore clean, controlled ventilation.

Installation Guidance

Allow the engine to cool, remove the necessary intake covers and hoses, then release the original separator carefully to avoid damaging surrounding connectors. Inspect breather hoses and seals while access is available. After installation, clear stored engine-management codes and check for vacuum leaks and stable idle operation.
