When buying a used Ford engine, it is important to remember that though these engines are meant for Ford vehicles, they are not interchangeable, so purchase only the one that matches your vehicle's specifications, states eBay. To determine the right type of Ford engine to purchase, take note of the Vehicle Identification Number and contact Ford to know the right type of engine to use. The owner's manual can be a valuable resource for this purpose as well.
Once the right type of Ford engine is identified, the next step is to locate a used engine for sale. Good resources for this task include local auto dealers, garages and online marketplaces such as eBay Motors.
It's always necessary to verify the engine's condition before finalizing the purchase. This may not be possible when buying a used engine online, so always ask for high-resolution pictures of the engine being considered. A free vehicle check using services such as Carfax, SaferCar or VINCheck may also be helpful in knowing the engine's mileage, its previous owners and if it has undergone a serious accident or major repair.
One inspection tip that applies to Ford engines is to pay attention to the color of the cast blocks, as this can indicate if the engine was well-maintained. If this is the case, the cast block should be silver in color. Otherwise, the cast block will be a brownish hue, which is often caused by oil corroding the metal.
