    Another 2.6L valve adjustment question

    Hi all,
    can someone explain the valve numbering and adjustment order for this engine. Is it as simple as inlet and exhaust #1 at front of engine and #6 at back, so to set inlet #1 exhaust #6 spring needs to be fully compressed. And should the inlets be set first then the exhaust?

    Cheers,
    Pete

    After a bit of research I think I know what I have to do. Adjust inlet first sequence 1-6 inlet-inlet, 2-5, 4-3 etc. Then exhaust the same way. Please correct me if I'm wrong.

    Cheers,
    Pete

    stretching the grey matter but I think the 2.6 works off of the rule of 13/7

    the 13's rule
    number the valves front to rear 1-12.
    when a valve is fully open take its number from 13 and the answer is the number of the valve that you should be adjusting

    and the rule of 7

    number the valve pairs 1-6 front to rear
    when a pair of valves are on the rock (one is just about closed and the other is only just opening) subtract that pair number from 7 and the result is the pair you should be adjusting.


    I do remember that as its a single lump cam profile and that if you start with #1 at top dead center and adjust all the valves that are loose then turn the engine over 360 degrees all the remaining valves will be loose and adjustable. (assuming that your valve adjustment ist horridly wrong to start with.

    Thanks Dave. The way I did it checks out with the rule of 7. Seems to run nicely now, better than my 2.25. I set the exhaust at 12 thou as suggested in some posts which leaves some tappet noise but apparently helps minimise burnt valves.

    stretching them gray matter cells again...

    I think the couple that I used to do I used to set at a loose 10 tho which seemed to keep the noise down and didnt seem to let the valves burn... well, never had to pull one down at any rate.
