Mitch...

you only need a comparison between cylinders to tell if something is broken or bent. If for some reason theres one cylinder being out; Have the mechanic perform a "leak test"(*) before he strips the engine down.

(*) Leak test= blocking the flywhell with the piston at TDC and closed valves, then applying compressed air through the spark plug hole and listening for any possible way of the air evacuating the combustion chamber. IE through dipstick (piston), exhaust(valve), carb(valve) or header tank (head gasket)
