But there's a whole bunch more to this story than just pumping air into a cylinder. Let's take a look at how to perform a cylinder leak down test properly and what you can learn from the results.

Horsepower and torque are all about cylinder pressure. Compression ratio, cam timing, cylinder head flow, and all the rest of the goodies that go into an engine ...

A similar test is for cylinder leakage, the difference being that instead of measuring pressure, it shows pressure loss.
