All

i have a 2012 Cooper R56 1.6L base. I am getting misfire on all cylinders while running.

Just purchased an OTC pressure gauge to do a compression test. I cannot find in the manual what the values are supposed to be, just that the compression should be 11:1.

My values where:

1: 230 / 220
2: 230 / 220
3: 210 / 230
4: 210 / 220

I am not sure these are correct. Other thread seem to have lower values. The values do seem consistent, so that is good ;-0

Any help would be appreciated. Going to try a leak down test this weekend.

Thanks in advance,
Tom
