Coolant Leak...

Just had and engine rebuild after a big end failure. All seems to be going well so far apart from a small coolant leak coming (I believe) from the water outlet pipe directly underneath the turbo (or is it the water feed directly underneath the turbo?).
My question is how easy is it to get to this area of the car in order to fix the leak. I guess the only way to get to this area is from underneath the car on a ramp?
With the sump shield removed is it possible to get to this area or will I have to remove the up-pipe in order to gain access?
Any ideas / does anyone know?

If I recall, both coolant lines come from the top. I can't view picture here at work or I'd check around.
