Dry/Wet Compression Testing - The classic wet/dry compression test is intended to detect worn piston rings by comparing cranking compression between a "dry" cylinder and "wet" cylinder. A wet cylinder is created by squirting a teaspoonful of engine oil through the spark plug hole to temporarily seal worn piston rings. Compression Test—Test Results The indicated compression pressures are considered within specification if the lowest reading cylinder is at least 75 percent of the highest reading. If one or more cylinders reads low, squirt approximately one tablespoon of engine oil on top of the pistons in the low-reading cylinders. Hence the term "relative". The principle of the relative compression test is based on tracking the battery current/voltage changes during cranking to determine the compression values of all. All 4 fuel injectors must be removed from the engine during each cylinder test to obtain valid test results. Note: The engine cranking time for the compression test should be less then 10 seconds and at 30 second intervals. there is something wrong as minimum cylinder compression is 356psi. you really need an un-oiled and an oiled result to see whats wrong. it could be a number of problems such as worn rings, head gasket, warped/cracked head, intake/exhaust valves riding.
