The Oil Gusher

[gmcnoob]

I have large amounts of oil pooling up around the intake manifold bolts on the passenger side rear. The valve cover gaskets were just completely redone by a mechanic and I am sure that is not where this oil is coming from. Please have a look at the pictures let me know what you think.

Is it possible that oil is coming up through those bolts?

Notice the oil dripping from the vacuum advance. Is it possible that oil can leak from there or is it just being splattered there somehow?

I just need to know what I should try first... Lots of posts say to reseal those bolts. I took about 100 pictures this morning from every angle. If there is something else you need to see please let me know. I greatly appreciate any advise on this.
