You can check the weep hole on the front neck of the waterpump for starters. You can also get a small hand mirror to look at the underside of the turbos to see if its the water pipes for them.

Double check all your hoses and clamps as well. Did you replace the lines? If not, you may find yourself doing that sooner than later whether you want to or not. Ask me how I know that one. ;)

I've found that nearly all of my little water leaks over the years were due to my failure to properly tighten the clamps or get the hoses on far enough.
