The PCV valve on a 2002 Chevy Cavalier is located on the back of the valve cover. It is a plug in type.
A 1997 Chevy Cavalier typically requires 5W-30 motor oil for optimal performance. It's important to use oil that meets the API (American Petroleum Institute) certification standards, preferably with a rating of SG or higher. Always check the owner's manual for specific recommendations based on your driving conditions.
The type needed is listed on the cap-where you place the oil.
