Quoting Removed, click Modern View to seePressure has nothing to do with that movement. The only thing acting to move the rocker toward the lower position (intake control out of pump housing and exhaust into pump housing) is a spring behind the intake control valve. The control arm can push against this spring and compress it so as to move rocker all the way up against the pump housing during lift command, but control arm can not pull rocker back away from pump housing. Arm can be relaxed such that the spring can push intake control valve out of pump housing and thus the rocker away from housing and as a result push the exhaust valve spool into the pump housing, resulting in lowering. Control arm can push but not pull.

That makes sense wasn't sure how it operated. I assume my next step is to drop the pump to fix the exhaust valve?
Or is there another way to test?
