Kyle, my 104 engine was seeping coolant down the block in the same area as yours. But it would only leak when the engine cooled down. Maybe a day an ahalf later. White streaks down the block and oil pan. My INDY took a pressure test and it showed no leakage. I was possitive it was the o-ring to the water pump, he could not be sure about it. With a small mirror I could see that weep hole on the pump and it was dry. It had to be the o-ring to the block and pump. It was that o-ring, and I replaced the pump since I was there. Not an easy job on the 1990 300CE, it was a rotten job. Good Luck
