how do you tell the difference between a ticking lifter noise vs noise from the valves hitting the seats? i have OF 1.0 with the newer comp hyd rollers. it makes some noise once it warms up, but with a mechanic’s stethoscope the noise seems about the same everywhere. over 30 psi at hot 1000 rpm idle and makes kind of a “snikt” sound.
basically once the forged 2618 pistons warm up enuff to stop slapping, the valvetrain starts making some kind of noise. it’s always something!
