Find used engines on sites such as UNeedAPart.com, BuyUsedEngine.com, AutoGator.com, Craigslist.org and eBay.com. Each site offers different tools for sorting through available engine listings, which are filterable by manufacturer, fuel type, or the number of cylinders in the engine.
Sites such as AutoGator.com, Craigslist.org and eBay.com contain used and remanufactured engines sold by dealers and private sellers who currently carry that item in stock. Alternately, UNeedAPart.com works as an online portal for connecting consumers with different auto salvage yards throughout the United States. As such, users need to submit a request for a specific engine in order to initiate a search for that model.
