M117 compression test results

I dont have the paper in front of me, but did a compression test today on my 560. As I recall, the passenger side was 159-161 psi for all four. Very close. For driver's side the second from the front read 165 and two were about 159 and one at 154. Milage is 163k miles. Tested when warm.

I am not sure what they should read. They are all pretty close, so thats good!
