Where is the oil coming from

[Audibot]

Sorry if I didn't search hard enough...

Since my B7 got totaled, I resorted to upping the timeline on getting my C5 going. Just completed changing the timing belt, water pump, thermostat, cam seals, half moons and gaskets (with sealant applied in correct places), valve cover gaskets (with sealant applied in correctly places) front crank seal (with new bolt), serepentine belt, JHM EFK install, coolant flush. Engine started up immediately and was running pretty smoothly. Couple codes for EGTs and an O2 sensor, but I'm not concerned with those.

However, after parking it for the night, noticed some oil had leaked. It is coming from the passenger side, directly underneath the oil pan. I did not notice any oil leaking from the rear, front, or driver's side of the pan--just passenger side. But I can't tell where's coming from, since the upper part of the oil pan (where it connects to the block) looks clean and free of any fresh oil.

HALP!

passenger side turbo drain, its just an o ring where it enters the upper pan, mine are starting to seep after 180k miles. oil level sensor? those are the only 2 things I can think of right now on the passenger side of the engine.

Thanks! I'll be sure to check the return line. Someone else had also given me that suggestion

Found the source! Was not a turbo line at all. Required an endoscope to actually find it, but here it is:




What it looks like is some ass-clown used a pry bar to try to adjust the alternator belt or something, and end up putting a small crack in the block. Oil was going to be flushed out anyway with the Liqui-Moly engine flush, so after the oil is drained, it'll sit that way for a little bit, the area'll get cleaned, and some JB Weld applied. Once that has cured (shouldn't be long with the weather right now), system will be refilled with oil and hopefully good to go!
