If there is oil pressure in the lifter, and zero lash, how is it loosing lift?
About the oil squirting, I am starting to think that the valve train geometry was incorrect. With such a mild cam i dont know. Oil pressure does that? not bad valvetrain geometry pinching the rocker bleed hole, and increasing the pressure there ? Once the rockers were loosened they all oozed evenly. No noise cold or hot.
The little things are nice to know.
