I don't even use air pressure, I just turn the crank to where both valves are closed for a given cylinder, then pull the rockers and remove the springs. The piston will be close enough to TDC to prevent the valve from falling in.
What is the normal compression pressure in the cylinder? I suspect we shouldn't go over that. Also keep your hands clear as the engine could rotate quickly when the air is applied. :eek:

Thanks for the tip BBA, I used your method, it worked great. I started to pressurize the cylinders, but it was too hard getting the air fitting in the sparkplug holes.
