I have a 350 Chevy engine with frozen pistons. I've tried every type of penetrating oil I can think of off the shelf. I've managed to get 3 of the pistons out, but the rest are rusted in tight and won't budge. Any advice you could give would be greatly appreciated.
Thanks, TDamon

If they are rusted in place that badly, I question if the block is any good even if you remove them. It seems as if there would be excessive damage done to the cylinders. Tell me what you have done to remove them. I know you used penetrating fluid, but are you tapping them to remove them? Is the engine out of the vehicle and taken apart?
