From a single valve cover gasket to a complete tested engine, Mason’s Auto Store carries engine parts for Toyota, Honda, Ford, Chevrolet, Subaru, Jeep, Porsche and other popular makes. New genuine OEM components come from factory supply, while complete engines and larger assemblies come from salvage vehicles and remanufacturers, each one inspected and tested before it is sold. Every product page lists the OEM part number, the model years it fits and any engine-code notes, because the same model can use a 2.5-liter four-cylinder in one trim and a V6 in another. Engine mounts, drive belts, tensioners and gaskets are the parts that keep an engine quiet, dry and aligned; replacing a cracked mount or a leaking gasket early prevents far bigger repairs later. If you are buying a used or remanufactured engine, tell us your VIN and engine code and we will confirm the match, note the mileage and explain the warranty in writing before you pay. Mechanics and fleet managers can request bulk pricing on gaskets, belts and mounts with one inquiry. Our Battle Creek team has sourced and checked engines and engine parts for decades, so you get answers from people who know the work.

Buying guide: Engine Parts
Match the engine code
Check the engine code on the label or in your VIN (8th character on most US vehicles). Mounts, gaskets and belts often differ between engines in the same model.
Used & remanufactured engines
Complete engines are compression-checked or run-tested before sale and ship on a pallet with freight insurance available.
Machine-shop know-how
Mason's has offered valve jobs, flywheel resurfacing and press work since long before online shopping.
Engine Parts — FAQ
Are used engines tested?
Yes. Used engines are inspected and tested before listing, and the mileage and test result are recorded on your invoice.
Which belt do I need?
Belt length depends on the engine and whether the vehicle has A/C. Use the vehicle filter and check the fitment notes, or send us your VIN.
Can I get a quote for several engines?
Yes — use the bulk inquiry form with your VINs and we quote availability, condition and freight.
