thanks for the ideas guys. I rebuilt this engine so I may have ended up with some oil in the water galley somehow. The oil is clear as when I poured it in from the bottle. I did use prestone green anti-freeze and will probably stick with that.
Ronnie, yes it is an automatic, I never thought about that aspect of it possibly being a hole between the trans cooler and anti-freeze.

I will give it a flush this weekend and start over to see if maybe it was from the engine build or if I really have a problem somewhere else.
Thanks for the input guys,
Wade
