Thanks for the answer. I almost figured that I broke them during disassembly, even though I was able to push the pistons out without any significant force. Will check for carbon deposits on the crack to verify.
What do you guys recommend to remove the rust powder deposits in the water jackets? I have not been able to find a place that does specifically block cleaning over here only a place that could drop the block into a ultrasonic bath.
...same with checking for cracks, seems like it is a non-existing issue, have not been able to find a shop that would do that....
Although I haven't tried this stuff, it is used by the Navy to do all their rust busting on the repair of the engines on the boats. I've considered buying some and figuring a way to flush the water jacket/passages by blocking all but a couple of holes needed to circulate the stuff. Could mount the head as well using FormAGasket to seal the head/block interface. Maybe mount a water pump & drive it with an electric motor. Just something I've thought about. Any other ideas on this??
