block pressure test
I suspect extreme pressure in the coolant system is a problem with the engine block or I messed up when I changed the head gaskets. I have fabricated an engine pressure check/leak tester and would like to know if the same psi used when checking the radiator/cap/hoses is sufficient? That may sound like a dumb question to a few of you here(I am very sorry if it is and has irritated you to the point you must insult me). I am hoping it doesn't require as much pressure as a firing cylinder; as of yet I have not found an expansion plug the size to seal off the coolant pump inlet. If the test only requires 15-17 psi the rubber plug I have secured with gorilla tape will most likely hold. I have never had to perform a pressure check on an engine block but my experience testing INS systems; some chassis(which flex when pressurized}required higher psi to force verification of the failure. I want see if that has been the case on some engine blocks although I doubt an engine block could flex. Thanks to all.

I don't know enough about these blocks to argue but Turner Engineering UK builds and sells new and remanufactured blocks with ductile iron flanged liners(sleeves). They also sell the sleeves separately so its possible to "remanufactured" your original block here in the state and not have the shipping costs of your core block and the delivery of the new/rebuild. From what I see navigating their website their new 3/4 blocks are cheaper than the remanufactured. I suspect I either misunderstood or it is harder to re-sleeve a failed block than it is to pour a casting. BTW; Thanks for the link; I hope mine fails the same except my steam cleaned cylinder is #4.
