i know its not exactly polo but does any one know the compression in the i was getting readings of around 150 psi (10ish bar) on all four cylinders is that about right??

Autodata says 9~12 Bar 130~174 psi so you are looking OK :-)

Nige, sorry to ask.. can you find out what compression a g40 (PY) should be reading?

Thanks chap
