    Can you guys give me your input on my compression numbers please?

    It's a 2013 PX 25 hours, my concern is the difference in cyl # 2. Should I be concerned? That much difference wouldn't cause a slightly rough idle would it? I did the test 3 times on a warm engine with the plugs in, throttle open.
    cyl #1-- 145
    cyl#2-- 137
    cyl#3-- 145


    thanks in advance.

    5% Difference I would say is acceptable IMO. Keep an eye on it and see how it changes over time.

    Exactly! Working on that now

    Using JB weld on the head, hope it works out
