Please check notes in each part listing to ensure the Crankcase Breather Cap is correct for your 1956 CHRYSLER NEW YORKER with a 5.8L 354 engine. GATES & STANT are competing brands, and each brand's Crankcase Breather Cap may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Crankcase Breather Cap fits only certain 1956 CHRYSLER NEW YORKER models.

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

After choosing a Crankcase Breather Cap, 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 CHRYSLER NEW YORKER 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 1956 CHRYSLER will not be lost if you switch.
