To find the correct part number, you need to:
1. Identify your engine: Look for an engine code stamped on the engine block itself. This code will help you determine the exact engine type. Your vehicle's documentation (owner's manual, etc.) might also specify the engine.
2. Use a parts website: Once you know your engine type, use a reputable auto parts website (like AutoZone, Advance Auto Parts, Napa Auto Parts, etc.) and enter your vehicle's year, make, model, and engine code. The website will then show you the correct PCV valve part numbers for your specific vehicle.
3. Check your local auto parts store: You can also visit a local auto parts store and provide them with your vehicle's information. They can look up the correct part number for you.
Without knowing your specific engine, I cannot provide a definitive part number.
