1-Compression test. This tests the state of the 'bottom half' of the engine and the valves and seats. All cylinders should should be within 5 psi, and near the high end of spec. If your compression gauge is old or of poor quality or the vehicle battery is suspect, look only for equality between cyliâ¦.
