Please check notes in each part listing to ensure the Valve Lifter is correct for your 1977 MERCURY MONARCH with a 4.1L 250 1BBL engine. Special restrictions like "California only" or "with sport package" may indicate a Valve Lifter fits only certain 1977 MERCURY MONARCH models.

Clicking a "More Info" link will display a picture and/or other details about that Valve Lifter in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Valve Lifter, 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 on "Find More Parts", to find more Engine parts, other MERCURY MONARCH parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1977 MERCURY will not be lost if you switch.
