Hello again. So I had another question about valve lashing. I have a 74 Chevy with a small block 350. I lashed the valves starting at the number one cylinder. rotated the motor by hand with all spark plugs out, and intake and valve covers off. Watched the exhaust valve rise and fall and then the intake rise and fall to make sure that both valves were on the bottom of the cam lobe. Then I lashed both valves. Now, I know if you ask 10 different people you will get ten different answers on the "right way" to lash. So the way I did it was by moving the push rod up and down while tightening the rocker bolt until all the up and down play was out, then I turned the rod between my fingers intull a change in resistance was felt in the spinning, which should be "Zero lash", then tightened a half turn more. After that was done the same procedure was followed on all the other cylinders in firing order. My question is, after the valves are all lashed should any of the rockers have any slight play in them and should the push rods be able to turn? I lashed the valves twice this way and after i was finished I went back and wiggled eache rocker arm and turned each push rod and fount that some of the rockers had a very small amount of play, some push rods would turn between my finger. HMM....lots of and any advice is appreciated. Be advised, this enigne hasnt been worked on in over 20 years. It ran when I got it, but had a rocker arm that was broken. I have replaced the timing chain cover, front main seal, water pump, thermostat, intake and valve cover gaskets.
