Sorry. So many words and I've been relentlessly picked on all day. 
Anyway. This may be a dumb question, but are you sure you have the correct filter on? That leak could be a number of things. Most popular being the back of the intake.

I think so? a shop changed the oil. it did seem like it got worse after the last oil change and i took it back to them adn they couldn't find the problem. As for the intake it was done in 2008 and the person who did it says its highly unlikely it would be leaking again.

well i just got back from a shop and they say its the intake leaking on the back of the drivers side and wanted $550 to fix it. i didn't get it done. coincidently that is exactly where the OPSU connectors are. They also managed to put a bunch of scratches in my drivers side headlight cover that i had to use scratch x/swirl x to tone down 
why can't shops work on cars witout scratching stuff up? their sister shop put 3 DEEP scratches in the same ******* headlight cover 2 years ago during a radiator install and i had to take it back to teh body shop that had painted that door 1 freaking week earlier and have it repainted. luckily these aren't that deep but still, ugh.

do you have a lot of tools? i don't really have a lot of tools here. I'm not sure what i should do at this point because if its leaking again after so few miles that might mean there are bigger issues? I was under the impression that the intake is not pressurized but whatever is leaking on my car definately is.

The Angle Fitting #2 will require the removal of the EGR valve.
Good luck, and be patient.

OP,
I think you should buy yourself a set of tools and start working on your car yourself.
At first take it steady to learn your engine bay and know where things are and how to open/access them. Shoebox's website will help guide you a long way. He goes as far to note down the wrench/socket sizes needed. You will memorize them quickly as well.
Good luck with your decisions.

The EGR nuts are 1/2"-not metric.

Heat from the EGR and crank case blow-by are the biggest contributors to rear China Wall leaks.
A few reason why the leak recurs:
Surfaces NOT thoroughly cleaned of residual gasket material, oil, etc. before the re-install, and
Dimples not made to the China Walls AND the underside of the intake manifold, and
Not an adequate amount of sealant on both China Walls which carries up onto the intake gaskets, and
Intake not set straight down, and
Incorrect torquing of the manifold bolts and not repeatedly re-torquing them to take into account the gasket taking a set.
You really need someone who KNOWS how to do this job RIGHT or the issue will return down the road.

I'm going up to illinois tomorrow to have Blackbird87 change it. Hopefully that takes care of it. I went and got the felpro gasket kit ($15) and a spray bottle of The right stuff ($15) just now at autozone. with what i'm paying him, i'll be a lot less into it than $450-$550 which is what the 2 shops wanted to charge.
as for torquing/retorquing, how long do you need to wait before retorquing? i don't think i ever touched the manifold after it was changed the first time.

Completely unnecessary.

If those fittings have never been out I doubt thats the leak. When I have torn down LT1's I belive they have red locktight on them from the factory. I have had those OPSU's leak at the fitting tons of times and I just started using teflon tape on them. Now no leaks.
