Rocker Arm help
Rat,
I am not wrong, but you are. Again. Probably set up more valve trains than you have had hot dinners. Notice how nobody is jumping in to defend you?
Put your glasses on & look at post #1 again. With valve closed, it shows the roller tip off centre to the exh side; with valve open, the roller tip is about to run off the edge of the valve on the exh side??????????
The rocker is effectively to long for this set up. Somebody in post #19 could see the problem, suggested lash caps like I did. See also post #15, working the saddle. They get it. If this rocker was raised up using shims to 'fix' the problem, the rocker would be at a very extreme angle at max lift; p'rod might bind in the cup & even contact the back of the rocker.
This rocker needs to sit lower in it's saddle if it is to be used. This will bring the roller closer to the intake side of the v/tip, valve on the seat, such that it rolls across the centre towards the exh side for a centered pattern during the lift cycle.
