Long story short, my vette has had water in cylinders 1 & 3 for quite some time - changed head gaskets many years ago and that didn't seem to be the problem - had the (aluminum) head pressure tested for cracks/leaks and no joy - so it must be the block?!?!?!
is there anyone in AZ that has the ability to run any of these tests (on my iron block) http://www.enginebuildermag.com/2012...nd-correction/ (obviously using the mot reliable method)
by coming to my home - since obviously the car doesn't run
