cylinder compression test

M3coupe · 06-26-2013, 05:13 PM

On my phone so cannot search but I don't remember seeing a post on this for E9x. I have done them in the past for E36, E46 but both were NA motors. Can anyone comment on this process for N54 and if so what is considered "the correct psi range" for individual cylinder? Thanks
