This is a project car i bought not too long ago, i went to a mechanic and he told me its either a Head gasket leak or a some sort of value leak if anyone is 100% sure or just knows what they are talking about, can you please give me some direction on what to do or what needs to be done i just need help, its also old oil build up at the bottom near the oil pan/ on the oil pan i don't know if that can help with anything i'm just noting every problem that could possibly coordinated with the main problem

P.S the leak is right below the alternator

 

If the dampness shown is the main concern, that's not a head gasket leak - it's way too high on the engine.

As someone mentioned in your previous thread, the plastic coolant elbows are a notorious failure point and are right there under the alternator. That certainly would be the #1 suspicion without having any other data.

But I still stand by what I'd mentioned in your other thread- Id take the time to clean all of that gunk off (carb cleaner, pressure washer, etc) first as it'll make it much easier to see where its coming from- not to mention when you go to actually repair it. Same with oil build up on the bottom - could be a main seal, could be VC gaskets, etc etc - but starting with 100% clean surface will make the leak path more apparent.

 

I have a question, do you think its possible for it to be some sorta oil leak? while i cleaning it off it appears as this

 

It's certainly possible. Is the supercharger still full of oil? It's rare for them to leak, but not impossible. All of its oil is held up front in that snout area.

Also depending where that swipe was from, could be engine oil coming out of the LIM valley end gaskets.
