What is normal cylinder compression?

Healthy engines should have compression over 100 psi per cylinder, with no more than 10 percent variation between the highest and lowest readings. With a compression tester, a few hand tools, and 20 minutes, you can try this yourself.
What is acceptable engine compression?
As a general rule a compression of 135 PSI or better is excellent. Similarly, a compression of 85 PSI or lower is extremely bad. The most desirable situation is that all cylinders, give the same or close to the same reading. Furthermore, that reading should be above 135 PSI.

Do not use any type of tool to get it tight. When you’re ready, have a helper crank up your Honda as you observe the needle on the compression tester’s gauge. Once the needle on the gauge stops climbing, have him or her stop cranking the engine. Record this compression reading on a piece of paper.
What happens when there is no compression on all 4 cylinders?
When you have a situation where you have no compression on ALL 4 cylinders, you’ll see: The engine cranks very fast and this fast cranking speed is very noticeable. The Ignition System is sparking all 4 spark plugs, so you know it’s not an ignition system problem/issue. The fuel injectors spray fuel. You can confirm this with a Noid Light test.
