Oil Leak Help

[sluhbmet]

My "new to me" bone stock e99 with 210,000 miles has an oil leak down the rear drivers side of the block and the front of the transmission bell housing. Most of the area seems to be damp and crusted but there's never any spots left on the driveway. I did some reading about turbo o-rings leaking, CCV issues, and (God forbid) the rear main seal that could cause symptoms like this. I've included a pic of the area in question. Does anyone have any insight on where the leak might be coming from? Thanks for all your help.

Mine leaks on the driveway about the size of a quarter in a week,don't know where it's coming from but it exits at the same place as yours.

Here's an interesting video, BUT I have to warn you about this guy,,,, he makes Great Videos, that Does NOT make him infallible though. He's got some really GOOFY theories (not about this though) So, don't take him as your Guru, as many do Confirm his advice on anything else he says

If its like mine, you can look under the turbo and see lots of oil under it, as well as oil in the valley (under the turbo).

Turbo Pedistil O-Rings... mine need to be done.... hopefully this summer.

Oil cooler O rings, Mine leaked above the oil filter and the O ring went bad. Diesel O rings has a kit to replace both O rings front and back.

I bet its the fuel drain valve orings on fuel bowl. Simple fix if it is. Do you smell diesel while starting up or driving?

Looks like oil cooler leak to me. Everything else mentioned in here leaks on the passenger side.

Thanks for all the replies. I checked the fuel drain valve on the back of the fuel bowl and it's dry as a bone and doesn't smell like diesel when running. I plan to get out there tomorrow and look in the engine valley for pedistal o-ring leakage. I hadn't read anything about oil cooler leaks yet. I will also try and focus on that area while I'm out there. Is the kit hard to install, if it is the oil cooler leaking? The main thing I need is some dry weather with no tornadoes here in Arkansas so I can actually get something done.

Mine leaks in the same general area, and I was told by very reputable source here that it was some sort of galleyplug in the block, and it was not that significant as of now to worry about. It would require pulling the turbo and possibly even a head.
