Compression Testing and What You Can Learn From It - EricTheCarGuyHere is a video on performing a compression test on an engine to assess it's mechanical con.Comparing measurements between cylinders is important. Running compression at idle should be 50-75 PSI (about half cranking compression). Snap throttle compression should be about 80% of cranking compression. Let’s analyze the results from the following sample test readings. In Example 1, cylinder #1 has a snap test reading that is If you have low compression. Modern engines with smaller displacements don’t have as much piston and cylinder wear as the big V8s of old. So, if you have a smaller engine with low compression, you can do another test and possibly avoid a full engine rebuild. A “wet” compression test can be done after the standard test.

While we’re not looking for specific numbers, let’s say that running compression at idle for an average engine is roughly 80-90 psi. The resulting explosion inside the combustion chamber causes the pistons to move and the engine to run. . Always carry out a compression test to confirm that the engine has low compression in one or more cylinders. Leave .
running compression test procedure
Start with a normal ("static") compression test. To eliminate rings, valves, holes in pistons, that sort of things. A normal cylinder balance test is also helpful (so you know which, if any, cylinder is presenting a problem). . Say the engine is running at 18 inches vacuum. Atmospheric pressure is about 30 inches, so the difference (30 inches .
Running the Test. Before we get started, let’s talk about equipment.
