Re: Removing stuck piston

[DAN ANDERSON]

For me it depends on if you are trying to save the rod and wrist pin or just the block? It can depend on if it is a motor has a head or not. Of course where the piston is in the jug matters. Assuming you are just saving the block, I drill the piston head around the wrist pin area and even the wrist pin bosses. Drill through the dome and make sure you don’t hit the block if it is a headless block. After a couple of good strikes with the biggest piece of shaft material that will fit inside the area, the piston usually will give way. After that it’s just a matter of knocking away any left over pieces.
