Leak Down Test for Keeping Healthy Car Engine

What is a leak test? Are you aware of it? This is a test that tells you about the working conditions of your machine and the main difference is that it doesn't measure pressure but actually measures pressure loss. In this test, it is important to remove each spark plug and then the crankshaft is turned and therefore each piston reaches the top after the cylinder test. There is an ignition sequence in the cylinder and people usually start with the first cylinder. 

When a leak is found, they basically install a leak gauge and then plug it into the cylinder. If there are no problems and the machine is running in good condition then the leakage should not be more than 5 to 10%. But yes, if the leak is around or more than 30% then it is worrying and needs attention. Fix this problem ASAP. The best part is that this test is very simple and doesn't take much time.

Not only that, but with a leak test you can also diagnose other problems that are happening to your car and that is done together with the compression test. When there is a problem with poor compression with very minimal leakage then the problem is with the valve train. There are different reasons behind different problems. So in order to avoid any obstacles in the future, it is very important to solve them before any major damage occurs.
