How to Test a Used Motor Before Buying It?

If your car’s motor has stopped working, there is a high possibility that people must have suggested that you find used motors for sale in a junkyard.

It is a common practice here in the USA to save some bucks by buying a used motor, instead of spending on a new one. Although, for someone who has never been to a junkyard, some reservation about the idea is expected.

The thing about junkyards is that it is a matter of sheer luck, you may find an unbelievable deal, or you may just end up wasting your time. Even if you find a used motor in the junkyard, you’d like to test it before buying, right?

Therefore, you must read on to discover a few ways to test the functionality of used motors.

Compression Test

To ensure that the used motor you are buying is fit to install, you may conduct a motor compression test which would allow you to assess the condition of valves, valve seats, and piston rings. Through this test, you would also be able to get a compression reading of each cylinder.

Ideally, the average reading of each cylinder should be over 100 PSI, and there should not be more than 10% deflect in the highest and lowest readings.

Since it is a technical maneuver, you may also consider hiring a certified technician but make sure the junkyard allows you to test the motor before buying.  

Compatibility Test

Apart from the condition of the used motor, it is also imperative to make sure that the motor you are about to buy is compatible with your vehicle.

Since there is seldom any return or replacement policy at the local junkyards, if you end up with the wrong motor, there won’t be any solution for that. For this reason, it is recommended to do a compatibility test.

You will need your VIN for this test. The VIN is a special number assigned to every vehicle which contains the engine code and is quite helpful in finding a new/used engine. When you buy a used motor, you don’t need an exact match but a motor that matches the specification of your VIN, turbo, and production date.

Easier Option? Buy Used Motors Online 

All this may sound like a fun weekend activity for mechanics and hands-on people. But many may not want to go through all this trouble to find a used motor when there is a better alternative available.

Those looking for motors and transmissions for sale near them can buy one online with much more ease and convenience. The online sellers of used motors would only need your VIN, and they’ll ship your desired used motor with a warranty & assured quality. It is an option worth considering.

Final Thoughts

A junkyard is a strange place where you may find anything and everything, but the quality of your discovery depends on your luck and a keen eye for desirable things. It may be quite appealing in some cases but when buying a used motor, it is best to avoid junkyard-diving and buy a used motor from a reputable supplier who would sell you only a high-grade motor with a reliable warranty policy.
