Does anybody can help. I know there's one way to build one air chuck to drive air inside the piston thru the spark plug hole using one piece of the spark welded in one hose connector. If anybody could help me with one picture so I can build one to work in my truck. Thanks

If you REALLY wanna be redneck about it -

Pull the plug wire off #1.

Pull the plug.

Beat all the ceramic out of said plug.

Take 1/4" air hose fitting, weld to steel remnants of former spark plug.

Screw back into cylinder and hook up air.

Rope trick's easiest for me, just remember to turn the crank the opposite way when done to remove the rope. Sounds silly, but you wouldn't believe the Volvo guys that have tried to break the caps out of pistons trying to keep compressing the rope.
