Hi NAM!
Can anyone lead me to a how to for Pacemans/ Countrymans on leakdown/ compression testing? I have a 2013 JCW Paceman with 25K miles and was wanting to know how to do a leakdown and compression test. Does anyone know the procedures or has done it and can inform me or lead me to the right direction?
Any help would be greatly appreciated.

i've never done a leak down test. but compression test is pretty straight forward. on cold engine the numbers are lower than hot engine. the number i see on my engines range from 170 to 190 psi.
