When replacing valve springs, what is the best way to keep the valves from falling in the piston chamber? Also, is there play between the pushrods and rocker? :confused: Thanks for info.. :chevy :seeya
If you have a compressor, there is a fitting that goes in the sparkplug hole, also a magnetic tool, or if your like me( dirt poor) you get a friend to hold the valve while you change the springs and install the keepers.There is no play between the push rods and the rocker. On a solid lifter cam there is a lash adjustment between the rocker and the top of the valve stem. On a hydraulic cam , you preload the lifters....

What he said. I've always used the air compressor method to pump up the cylinder and hold the valve up.
On another forum I have read posts of threading nylon rope into the spark hole, then bringing that cylinder to TDC and the rope compresses in the chamber and holds the valve up.
