You should check the o-ring on the cam position sensor. Oil can leak out of there and drip down to the exhaust manifold or get blown back by the fan. It could also be valve cover gaskets or cam seals. Those are common problems. After checking those, I would look at the oil pressure sender and the turbo oil line seals.

As far as your oil pressure, once warmed up, you should be at 4-7 psi at idle and 35+ at about 3000 RPM.

Okay 2 questions in 1, if i was to take off the cam position sensor (1.witch is infront of the engine behind the powersteering res) 2.not knowing what im doing could i mess up the engine as far as not putting it back in right? i can see now that i do have a leak from there but im sure i have more than just that one leak.

This will show you how to remove and reinstall it. I would also mark the position of the bolt with paint or something as it will help you to get the timing set right (or pretty close) after reinstalling. I definitely would check the timing afterward, just to make sure all is good. It's easy to be off a tooth after reinstalling. You can't really "mess up the engine". It will just run like crap, if at all, if it isn't installed correctly.

If you remove the accordian hose, you should also check the oil pressure sender and the copper crush washer on the turbo oil line as you will have easy access to them. These are a couple other places that could possibly be leaking.

Okay I think I have everything I need but I have one more question in the CPS diagram from the Cygnus website that SupraJim posted (right above this post) It shows an o-ring at the end of diagram now correct me if im wrong but thats not where the O-ring goes correct? it goes here right? Or does it have one on the other side of gear on the shaft(@end far left of pic) and one on right where it says O-ring in yellow?

There is only the one o-ring, and it goes exactly where it is in that image you posted, after the gear and alignment teeth

They call that technical drawing; it’s a clear way to illustrate parts or items, bog standard drawing office procedure worldwide. Many of the drawings on the cygnusx1 site are illustrated this way for clarity. An assembly drawing on the other hand would show the O ring in the correct position or an arrow pointing to its correct position.

i think that diagram is showing the o-ring that goes on the back of the shaft not necessarily in front of the gear cause look how it has a diamond on it i think its just pic to show you the parts involved with the piece.
