HI, Compression should be 128 to 156 psi, with no more than 14 psi. difference between cylinders.
Normal compression on a gasoline engine is about 125 psi.
standard compression is 178psi min is 142 psi. +/- 15 psi between cylinders. That's for the 2.2 engine.
200 psi
87 - 04 compression standard 121 psi minimum 114 psi max 128 psi
then youre running about 8.5:1 compression
With the engine off then turning it on, it should be between 23 to 31 psi. With the engine running, it should be 13 to 20 psi.
29 psi
251.37
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Engine compression psi? Radiator cap psi? Engine oil pressure psi? Tire pressure psi? Fuel pressure psi?
With a compression gauge.
