4 Things To Check When Buying A used car engine

Oil Quality Check

You want to check the oil's colour and viscosity. Darker oils may indicate that there is a problem with the engine, which can be checked by your mechanic. You will also want to check the jug's lid for signs of leakage onto the container. Generally speaking you don't want to buy a car if it has an oil leak as this points towards more problems later on.

Compression Testing

The compression test basically checks your engine's ability to make power, so it is important! In order to do a compression test you'll need some Gunk Motor Flush or something similar, a long thin tube and someone who knows what they're doing! Next just take off each spark plug one by one and insert the tube, pumping it a few times you will check to see if your compression is within range.

If each cylinder is coming out between 105-145 PSI then you're good, but anything below 95 PSI probably means you need a new engine or at least some major work done.

Leak-down Testing

For this test you'll need a pressure gauge and someone who knows what they're doing! You simply take off the radiator cap and turn on your car for around 10 seconds or so. Next check that your cooling system's pressure holds water for 5 seconds after shutting off the engine. If the pressure drops too quickly then there might be something wrong with your engine.

Basic Engine Inspection

This should be done by a mechanic not yourself as you need to know what's going on! But it basically consists of looking for leaks, water pump issues and other problems that need immediate attention. You'll also want to check the belts, hoses and all other parts for any signs of damage or wear as this could indicate a problem with your car's internal engine. Also don't hesitate to ask a mechanic for more information on what you should be looking out for when it comes to buying a used car engine.

Conclusion

Before buying a used engine always make sure to check everything yourself with the help of your mechanic. Generally speaking things like compression and leak-down tests tell you either where problems lie or if there are no problems yet, but these only work by getting someone qualified to look at them! So before making any decisions read up on how to do all of this yourself and then get in touch with your local mechanics and garages near you!
