QUOTE(rick 918-S @ Jan 21 2026, 07:09 AM)  I would just break the pistons and not worry about damaging the cylinders. There is no way you are reusing them anyway. Banging on the tops are banging the rods on the crank. Piston/cylinders are available new and the prices are no terrible. For my information only... haha How exactly do you break the pistons if the case is assembled? Just was trying to visualize and got curious, not sure how that is possible. |

In this case heat is essential to freeing up the seizure between the piston rings and the bores , continue heating and using penetrant ,don't be afraid to get the parts nice and hot as you need to break the rusted area ,a meduim size butane bbq lighter will do the trick ,cheers.
