Where is the PCV valve on a vortec v6?

The PCV (positive crankcase ventilation) valve on a Vortec V6 engine varies depending on the specific model year and design. Here is a general guide on where to find it for some common Vortec V6 engines:

Vortec 3.4L V6 (1998-2004):

1. Open the engine hood of the vehicle.

2. Locate the engine block on the driver's side of the vehicle.

3. Look near the back of the engine block, towards the top.

4. The PCV valve is usually a small plastic or metal cylindrical part with a hose attached to it.

5. It's often located either directly on the valve cover or on a rubber hose that connects the valve cover to the intake manifold.

6. Check your vehicle's specific repair manual for the exact location of the PCV valve for your particular model year.

Other Vortec V6 engines may have similar locations for the PCV valve, but it's always recommended to refer to a vehicle-specific repair manual or consult with a trusted mechanic if you're unsure.
