With the spark plugs out of the engine and a FULLY charged battery, give the starter a one second click and then stop. Observe as you do this if the fan or crank pulley has moved slightly, if the valves have moved, and if the starter is fully engaging into the flywheel. Take the breaker bar and turn the crank pulley back a bit and then hit the starter button again to put some torque on the flywheel. This torque multiplication will move the crank journal a degree or two and will push or pull on the piston which in turn will apply thrust against the rings. All you have to do for the moment is crack the rings loose a thousandth of an inch to allow the penetrating oil to get in between the rings and cylinder walls. | With the spark plugs out of the engine and a FULLY charged battery, give the starter a one second click and then stop.
