Taking an engine compression test is sort of like checking your car's blood pressure. It's a quick and painless procedure ...

Last month we acquainted you with a few unique procedures for using conventional tune-up devices—such as a vacuum gauge, timing light and electrical analyzer—for evaluating the efficiency and ...

Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

You might talk about it often, but do you really know what compression is all about? Every engine has to make it and those that don't are hurtin' for sure. But, here's the confusing part, for this ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per ...
