I'm thinking water getting into r/h bank of the block. Cracked block, head gasket leak, cracked head. There is no water in crankcase, water level in radiator tank does not seem to go down. I haven't torn into it yet. I'll remove spark plugs, put my camera scope in each cylinder on r/h bank. Could it even be intake manifold? What are your thoughts that I haven't thought of? Thanks

Since there is no water in the pan and water level stays the same, any possibility that the exhaust pipes may be rusted inside

Engine has been run 3 times before and this did not occur. This is new. Further looking will help define it closer. Thanks for your idea.

Could be condensation in the exhaust. Take a run on the highway and see if its still there.

Not ready for the road, yet. I'll have to use the bloodhound method.

If you’re just starting and warming it up in the garage, take a look at the heat riser valve on the rh exhaust manifold. If it’s stuck or doesn’t get hot enough to open when you’re running it, you’ll never cook the residual water vapor out of that bank at no load or idle.

Good thought. I forgot about the heat riser. I'll check it. Thanks Can I remove the heat riser altogether?

Short answer yes. But you’ll need to pull it, plug the shaft holes or make a spacer to bolt the head pipe back to the manifold. If it’s free or you can free it up, I’d just wire it open for the time being.
