    I did a leak down and dry/wet test on my stock motor with 165K. Are these numbers normal? Seems low but evidently the l67 is considerably less then the l32 due to one point less compression. Reason I ask is my #2 cyl seems to have an oil control issue. The plug with 5k miles had considerable amounts of oil deposit. Hard revs and engine braking I can smell oil in the exhaust but not during hard acceleration or cold starts. Im wondering (hoping ) its an intake leak?

    Cyl % Dry Wet

    1) 20 150 180
    2) 15 160 185
    3) 17 150 185
    4) 17 165 180
    5) 17 165 185
    6) 20 152 175

    L67 and L32 are the same motors. L36 and L26 are higher compression.

    Those numbers looks fine to me, I've seen 160-180 be the avg for most cars.

    Perhaps you have a PCV issue that is causing extra oil to be burnt or maybe even it's getting past a piston ring. Kind of hard to guess at it but if that's the only issue then I'd almost be at the screw it point and just swap the plug out often if it's getting past the rings.
