'83 300TD (purchased and resided in CA entire life) I decided to tackle what I assume is a leak at my turbo drain tube. When I ripped into the engine I found an unconnected nipple at the upper oil pan between the turbo train tube and what I though is an oil separator line. That had me scarring my head, until I moved the oil separator line and realized that it's never been connected. Before I tear into the god forsaken turbo drain tube, could this be the source for the oil leak?
