what im saying is i go to adjust them, but when i push down on the rocker with a screw driver the push rod sinks down a good centimeter or so, im wondering if the lifters are bad already or what, because only a couple cylinders do this (3 4 and 5) at any given rotation (valves closed obviously) and i tried just not pushing down at all and setting it when it felt pressure, but then when i turn it over it wont push down on the valve at all. im gonna talk with my local mechanic and hopefully he can help..
