After trying the aforementioned soaking to no avail, determine which cylinder is on the compression stroke by removing the spark plugs and using a compression gauge hose or other hose that fits snugly in the spark plug hole. Blow in the hose, if you can't easily then you have the one on compression stroke (if you use a gauge hose make sure it has no schrader valve in it). Break the porcelain out of an old spark plug and thread the metal body for a large grease fitting (1/4 NPT). Insert the plug in the compression cylinder and pump it full using a grease gun filled with cheap light weight grease (like white grease). Grease guns can develop thousands of pounds of pressure with no impact. Once the motor breaks free you can rotate the motor to squeeze most of the grease out of the spark plug hole. | After trying the aforementioned soaking to no avail, determine which cylinder is on the compression stroke by removing the spark plugs and using a compression gauge hose or other hose that fits snugly in the spark plug hole.

| + | Another approach is to put an Oz. of WD40 or PB Blaster in each cylinder and then pressurize with compressed air. On cylinders that are not under compression, the compressed air will distrubute the penertrating oil. With the cylinder under compression, the compressed air will act to rotate the engine while driving the penertrating oil past the rings. | ||
