You have obviously be at it with this one for a while. Lots of good parts thrown at it and still no better off. So lets try a different approach. Lets do some testing.

Perform a cooling system pressure test and an engine cylinder compression test. The cooling system pressure test will allow you to confirm if there are any leaks present, internal or external. The engine compression test will show if there is a blown head gasket.

Another quick test would be to install the cooling system pressure tester and start the engine. You know you have some internal engine issues if you start to see the pressure build way over the manufacturers pressure limit posted on the radiator cap. (15-17 psi)
