When is a Used engine the Right Choice?

By Jim McNeily

There are many reasons I can think of to buy a used engine for a car or truck with a broken engine. Used engines with low mileage are very affordable and are fantastic replacement engines for certain needs.

Let's say, for example, that you own a fairly new car, less than 6 years old. And one day the engine overheats badly. You are stranded on the side of the road on a 95 degree day and waiting for a tow truck to take you to your favorite engine repair shop. You may be thinking to yourself that this car only has 65,000 miles on it, so how can the engine stop working? You may also be thinking, "I'm not ready to buy a new car.

That is a good question and, most likely, will be answered once the mechanic checks out your car. Don't forget that it is critical to know why an engine failed, particularly on a newer car, or you may have another problem which may not be covered under the warranty, since it was a subsystem that failed and re-caused the problem.

In fact, if I had an engine failure pre-maturely, I would want to find out if an in-direct source caused the situation. We all know that a well maintained and properly driven car can get over 200,000 plus miles on the engine before it wears out.

So, you're back at the car shop. The mechanic has gone through a complete diagnostic routine and found the cause of the failure. He says, "You sprung a leak in the bottom radiator hose". When the coolant leaked out, your engine overheated badly enough to warp the heads and crack the block, and that the engine now needs to be replaced.

Here are my thought patterns on the matter and what may be the best replacement engine choice for you. Since we know that, barring unforeseen problems, like overheating the engine badly or springing an engine oil leak, the engine should go 200,000 miles or more.

Why not buy a used low mileage engine in good shape, repair the system that caused a pre-mature engine failure, and inspect all of the other systems that are easy to get at while the motor is out of the engine compartment? Then learn how to take care of your car and keep an eye on the 'small stuff' and drive the 200,000 miles you should have gotten the first time. - 29952
