Gear diffs are prone to weeping a little but the following will help...
1. Use something like AE green slime (as used on shock shafts) on the outdrive o rings.
2. Do not overfill (up to the top of the spider is about right)
3. Lightly coat the gasket with (Silicone) oil before installation.
4. Gently tighten screws in a diagonal pattern until snug. (This prevents deformation of the housing)
I built mine around a month ago and not lost a drop.
