As I went through loads of discussions and websites I probably found the couse of oil leak in here:

So now my question is where is that 'rear crankshaft seal' and how to change it. Believe me I've read loads of threads and wathed youtube videos but couldn't figer it out. I think it has some other name or so.
Unfortunately, if that's what it is, it is in single worst spot you can imagine, inside the bell housing, behind flywheel.
Ensure that this is where it leaks before you disassemble the whole thing. It is far more probably that turbo oil line or turbo line distributor are leaking oil and it might look like it is coming from bell housing since the would be dripping on top of it. Is the oil coming from inside one of the bell housing opening and there is no sight of oiil flowing around bell housing or is it just flowing on the outside surface of bell housing? First one would probably be RMS/oil pan seal, second would be something above it.
The only way to access RMS is unfortunately after removing whole transmission and then unbolting the flywheel/flexplate (depending which tranny you have). It is an expensive fix if you don't do it yourself.
