It might be darker in that area. Hydrogen being so small is sometimes very tricky and small leaks are hard to find.
With the right amount of HHO you should not have any smoke at all especially after running about 1000 KM or so and in my experience the temperature goes down not up. This will depend on the condition of the engine though. Have you had your injectors cleaned and pressure checked and adjusted? Has the pump been serviced and set?
