Quote: are you pushrod oiling? what lifters? is the block bushed? if so how big are the holes in the bushings? had a similiar prob. that I corrected,my mill was oiling way to much up top.I corrected It with a set of bushings with a.020 hole in the lifter.
we are using spray bars, i'm not sure what lifters, blocked is bushed and there are no holes in the bushings.
