Any new ideas as to what was or is going on?

When I performed the block fluid leak test the first time - while the engine was still over-heating if you looked at it sideways - the blue fluid turned green. I performed that test twice with the same results.

This indicates, according to another forum member who experienced a similar "green not yellow" color change, that there was exhaust gases entering the water jacket through the head gasket or crack or whatever.

Now that the engine is not overheating, the same test indicates that there is NOT exhaust gas leaking into the water jacket.

How can this be?
