Please check notes in each part listing to ensure the Valve Seat is correct for your 1998 NISSAN QUEST with a 3.0L engine. ENGINETECH, CLEVITE / PERFECT CIRCLE, & BECK/ARNLEY are competing brands, and each brand's Valve Seat may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Valve Seat fits only certain 1998 NISSAN QUEST models.
Clicking a "More Info" link will display a picture and/or other details about that Valve Seat in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Valve Seat, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Engine parts, other NISSAN QUEST parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1998 NISSAN will not be lost if you switch.
