Thanks for the great response to my hex bolt removal question, I was able to use the Crafstman Bolt Out impact type that has a center 3/8" drive set up instead of a wrench, it was the difference due to clearance limit.
Great suggestion.
Now that the camshaft is out I need to keep the valves up against the head in order to keep them from falling once I try to remove the keeper from the top side witout removing the head, I have a spring compressor.
How much air pressure do I need to inject into the cylinder and does it have to be constant or can I pressure it up with a electric bicycle tire compressor and leave it hooked up at about 95 psi.
I could purchase a small air compressor if needed fom sears or so.
Need your pro advise.
