Phat VR6 3 Posted July 17, 2008 Report Share Posted July 17, 2008 Hello, Realy easy matey, Unplug your coilpack. Remove a spark plug screw gauge in. Crank over engine untill it stops going upcarry out on all cylinders. ment to be around 11-14 bar iirc but best to see if they all match each other...Carry out hot as everythink is exspanded... but you can carry out cold aswellHope this helps Link to post Share on other sites
