So, how is it that it's now a blown headgasket that is keeping water from circulating into the cooling system?...after replacing all the other stuff......
sounds like a mis-diagnosis.......
Inquiring minds want to know. It's Unfortunate that the people you took it to didn't check for that, early on.
My heart goes out to you, man. Looks like you took the long way around, to find the problem. What has it cost you so far?-Bob
