Please check notes in each part listing to ensure the Piston Ring is correct for your 1998 OLDSMOBILE CUTLASS with a 3.1L engine. DNJ ENGINE COMPONENTS & SEALED POWER are competing brands, and each brand's Piston Ring may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Piston Ring fits only certain 1998 OLDSMOBILE CUTLASS models.
Clicking a "More Info" link will display a picture and/or other details about that Piston Ring in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Piston Ring, 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 OLDSMOBILE CUTLASS 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 OLDSMOBILE will not be lost if you switch.
