So I have had water leaks all over the place when I add water I can see a little oil in the (rainbow) the leaks are coming from a split connector on the t stat hose to the heater control and the top radiator connection under the top hose
Any thoughts

 

Check tail pipe for white smoke. Open up oil cap look with a flash light. When oil and water mix oil turns thick,milky. Also low oil pressure from coolant mixing with it

 

No smoke and no milky water
