So now it is a half year later, and I just removed the rockers to remove the round imprints on the faces of the rockers. I put it all back together, tried to adjust it initially cold to get it started, but it will not fire.
I have two other 216s in the shop with mechanical lifters. When the rocker is free, the slop allows it to rest either against the pushrod or the valve. On the 235, there is constant tension against the rocker. I can press on the adjustment screw pretty heavily with a screwdriver and get a feeler between the rocker face and the valve, but that tension is always there.
I am entirely inexperienced regarding hydraulic lifters, but I fear this 235 has them. Most probably I will never understand hydraulics until I strip down one of these motors. I need an answer to one question - if there is this constant pressure against the rocker can I assume the lifters are hydraulic and adjust them so? One more question - if I adjust them as hydraulics and they are not can I damage the engine?
These lifters have me pulling my hair out. One year ago I had a fine running 216 with a cracked block. Now I have a fine looking 235 that doesn't leak and doesn't run either.
