Almost done but have a question re: hydraulic lifter preload adjustment. When assembling the engine it was easy to watch the DRY lifters to set the preload, but with the intake on it's a bit more difficult. In the old days I would adjust them with the engine running, but I would not attempt that on a Pantera (oil every where). I tried to set them the way Crane said. When the exhaust begins to open adjust the intake, then when the intake opens full then is half way closed adjust the exhaust. I fired it up and had tones of rocker noise. Then I did each cylinder at TDC and had them too tight. Went back again at each cylinder and I've almost got them right. When adjusting I back off the rocker until the pushrod is loose then tighten untill the slack is out, spinning the rod, then 1/2 turn more. Do any of you experts know any other method? Thanks
