after loosening the two bolts from the back of the intake manifold, how do I possibly get to that threaded nut at the bottom the the egr valve?!? I need to clean it and check the hoses and the modulator filters as well

thx

Easy!
I just did this 2 weeks ago.
Remove the two bolts that hold the egr, then undo the large nut that holds the egr valve tube at the BOTTOM of the tube NOT the top that connects to the egr valve. There's a bracket that has to be removed to access this nut, but it's easy to remove it, only 2 screws hold the bracket down(I forget which bracket it is, but it's really easy stuff). So you should remove the egr tube with the egr valve as one piece, it's so much easier that way, + you can clean the tube as well this way!
When the egr valve/tube is removed, make sure you clean out the gunk of carbon that's most likely going to be wedged where the egr bolts into the fuel plenium:clap:
good luck and let us know how it worked out for you!

When you reassemble the tube, use anti-seize compund (I use the gray pasty stuff from Permatex, but anything, including C5A copper-colored compund will do).

I forgot all about that. Oh well, I guess it doesnt matter for me at this point

thx guys, hopefully, I'll get a chance to do it tonight. I'll trace down to where the tube ends and unscrew whatever bracket is there and also the nut holding the tube on.

Trust me, it's really easy once your doing it. It will come natural to you what to do once your in front of the engine with tools in hand.

The tube screws onto the back of the cylinder head.

Right!
....you cant miss it.
