Where is the PVC valve on a 1993 Toyota pickup V6 manual transmission?

The Positive Crankcase Ventilation (PCV) valve on a 1993 Toyota V6 pickup (3.0L 3VZ-E engine) is typically located on the valve cover. It's a small, usually black, plastic valve. It might be hard to see depending on the modifications or condition of the engine bay.

However, a precise location isn't easily given without a diagram specific to that year and engine. The best approach is to:

1. Consult a repair manual: A Haynes or Chilton manual for your specific vehicle will have a diagram showing the exact location.

2. Look closely at the valve cover: The PCV valve is usually connected to a hose going to the intake manifold. Follow the hoses from the valve cover; one of them will likely lead to the PCV valve.

Keep in mind that the engine bay might be tight, so you may need to use a flashlight and possibly even remove some components for better visibility.
