Where is the PCV valve located in 18 ltr engine 1994 VW Golf?

The exact location of the PCV (Positive Crankcase Ventilation) valve on a 1994 VW Golf's 1.8L engine can vary slightly depending on the specific engine code (e.g., 2E, ABF, etc.). However, it's generally found on or near the valve cover.

It's often a small, usually plastic, canister-shaped or cylindrical component with a hose connected to it. Look carefully along the top of the engine, around the valve cover. You might need to consult a repair manual or a diagram specific to your exact engine code for precise placement. A Haynes or Chilton manual for your year and model would be a great help.

Important Note: Without knowing your specific engine code, this is the best general guidance I can offer. The location could be slightly different depending on the specifics of the engine.
