Where is the PVC valve on a 1999 Buick lesabre?

The PCV (Positive Crankcase Ventilation) valve on a 1999 Buick LeSabre is typically located on the valve cover. However, the exact position on the valve cover can vary slightly depending on the engine (3.1L, 3.8L).

To locate it definitively, you'll need to:

1. Consult your owner's manual: This is the best resource as it will have diagrams and specifics for your exact vehicle.

2. Look at a repair manual specific to your 1999 Buick LeSabre: These manuals have detailed diagrams and instructions. Chilton and Haynes are popular brands.

3. Search online for images: Search for "1999 Buick LeSabre [your engine size] PCV valve location" on Google Images. This can help visualize where it's generally located.

The PCV valve is usually a small, plastic valve with a hose connected to it. It often looks like a small, capped cylinder. Remember to be careful when working near hot engine components.
