Industrial Engine Oil Separator Audi A8 Quattro S6 S7 S8 RS7 4.0T Engine Oil Separator

The Engine Oil Separator for Audi 4.0T TFSI engines isolates oil vapor from blow-by gases in the crankcase ventilation (PCV) system, helping maintain proper engine performance and emissions control. Designed for Audi A8 Quattro, S6, S7, S8, and RS7 models with the 4.0T TFSI gasoline engine, it installs at the engine valve cover assembly to restore and regulate crankcase ventilation. This part supports maintenance tasks and repairs by replacing worn or faulty PCV oil separators, reducing oil consumption and enabling the crankcase ventilation system to function as intended. Common replacements include the Engine Oil Separator, PCV Oil Separator, and Crankcase Ventilation Valve, reflecting its role as a standard component in Audi PCV system restoration.
