M104 oil leaks

[ytech15]

Hello,
I’m trying to locate the source of each of the following leaks;

1. Oil drops “hanging” from oil pan - where does it usually come from?

2. Wetness (no drops) around the passenger side rear corner of the engine. HG? or could it be a VC gasket? see picture

3. Oil drops hanging from the bell housing- rear main seal or perhaps oil travels down there from the rear corner of the block?

I’ve cleaned all of these locations but #2 as Ill have to tackle the cleaning from underneath..

Thanks
