Hi all. I am going to attemp my valve adjustment and timing tomorrow on my 54 truck with a 62 235 in it. I have gotten great advise and info from people here. I just want to clearify that I am going to be doing it right tomorrow. I have down loaded the 235 valve adjustment from the stove bolt page. I will heat up my engine and follow the directions. I still have a question regarding the zero lash that people talk about. I have the hydrolic valves so I need to adjust to these specks. Is zero lash when the screw on top of the rod is just touching it or is it when you can not spin the rod anymore? I want to make sure I don't want to have things to tight in the engine that it might damage something. Thanks guys, Scottys 54
I hope you got everything done properly. I didn't see your post before. Zero lash is simply the term that means no clearance between the valve stem and the rocker finger. Chances are the pushrods will still spin if you try to spin them, even if they are too tight. Chris
