Hey i have a small water leak coming from in behind the starter motor. I know there is a drain looking hole maybe from the valley behind it.

Could it be from the turbo water return??? Any other ideas would be appreciated. What other water gallerys are there in the back of the block/head on the starter side???

Cheers, Heath

The turbo is not water cooled. That went away in 04.5 when the LLY came out with the VNT.

I'd pull the fender liner and check the block heater first. It's installed in one of the freeze plug holes and is right above the starter.
