Good morning Adnrew :
The _first_ thing you needs do is : get that engine _Hospital_ clean so you can properly diagnose where the actual oil is leaking from .
Ther are numerous O-Rings , rubber pipes , elbows & grommets in that area that need periodic changing before the engine is reasonably oil tight ~ after I did them all on my '84 Coupe with it ruined engine & bad turbo , it still _used_ oil but didn't drip...
Be aware this is a vexatious labor job , a good (IMO) DIY candidate but _NOT_ for the boob who's doing the ball joints (3 hour job) on another member here's car ! many (? most ?) Mechanics get frustrated/lazy when faced with time consuming fiddly jobs and don't pay attention to the details , this is one of those PIA , detail oriented jobs , ask Tom he's watched me do it on his and my engines .
IIRC , under $100 in parts but BIG TIME labor co$t$ to do it right .

turbo oil leak
Hi all
I am writing with a question re my 82 300D turbo, 200k miles, original motor including original Garrett turbo. I have an oil leak that seems to come from the rear end of the turbo (e.g., where the exhaust leaves the turbo into the flexible part of the exhaust pipe). After a drive it leaves several drips on the ground. I am assuming that some rear seal within the turbo is leaking. I am writing to see if anyone can help me further diagnose this - is this reflective of some simple oil seal change, or does it likely mean the bearings and or impellar shaft have too much play and would also need replacement? I am willing to just replace the turbo if need be but it would be ideal for me to understand better what this type of oil leak means. The car has been well cared for including frequent oil changes, but the first owner (1982-1996, 125k miles) probably did not let it idle much before shutting it off. Thank you for any help.
Andrew
