[W126 Coupe] Wannabe Gullwing & Who know how to fix oil leaks on de cpe

[Josh Allen]

Regarding the oil leaks, I did the upper oil pan while the engine was on 
an engine stand, and found even that to be an adventure in aggravation 
just due to having to extract all the little hex head cap-screws that 
hold it on.

That being said, I seem to remember someone saying that it's possible to 
remove while the engine is in place, by doing some creative juggling and 
lifting the engine up off of the engine mounts to allow the pan to clear 
the cross member.

You might also consider scrubbing the engine down with an engine cleaner 
and see just where the leak is actually coming from.  I'd suspect the 
front main seal to develop a leak prior to the upper oil pan 
spontaneously doing so.  Both of my crank shaft main seals had done so 
on my 500SEC's replacement motor.

Best of luck in finding it, and hopefully it's something easy to remedy!
