    just look on cam it will tell you what valve you have to adjust if it says number as far as 3 means cylinder 3 intake and injector if you see V3 position means 3 exhaust, but need shims to adjust exhaust and need to adjust valve bridges touch plus 60 degrees this is not a beginer type of job if you have never done this before on d12 i wouldnt suggest it to do it properly it takes a little bit of experience.

    Yes I have done it myself last year. Doing it this year and and a Volvo mechanic told me I was wrong on doing it 123456 and the firing order was 536241 like in the manual.
    This is why I ask, I have done International tractors and Mcormicks. The manual is not specific on the part on which cylinder it is in conjuction with adjusting the valve.

    firing order shoud be 153624 and they have different set up on this engine you don't adjust like the old fashion way this is a little bit different you have the marks right on the cam of what you are supposed to adjust and when.
