TTS 8J Oil Leak

[ITP]

Hello,

I seem to have oil leaking from below my alternator. I'd checked the belt a week or so ago so it's a recent development. My concern is it could lead to the belt slipping and/or coming off which is a real pain in the backside.

I snapped a few photos, has anyone had a similar issue? Any advice on where this is coming from would be great, I can't see the source because whatever it is, is below the alternator. The underside is covered and because of the belt it's also sprayed about a bit.

Thanks in advance.

Could be valve cover leaking down a bit of oil and then being thrown around by the rotational parts
