Oil Leak behind engine

[roks]

Hi everyone,

Behind the engine seems to be getting wetter lately and somehow dripping on to the drive shaft.(both ends of the shaft are dry).

I replaced o-ring on chain tensioner few months ago, but no improvement. The bottom bolt seems to be wet all the time.

Could it be sipping out that to dripp? Would rtv gasket maker work?

Attached some pic....in no particular order..taken from the top, so some upside down.

Thanks in advance.
