how to clean egr stuff
so I'm getting ready to swap everything on my new long block (22re) and noticed my egr passages are almost completely caked shut with carbon
so how can I clean that stuff out without hurting the valve......

This can be a tough job; that "gunk" is a mixture of crude oil and concrete, so far as I can tell.
I did it on a 3.0, so it's the plenum that was full. I actually soaked it in the sink overnight with a lot of dishwasher detergent (I live alone; if you have a loved one you should get a big plastic tray -- don't use the sink). Then I had clean "concrete," and I had to scrape it (use a wooden stick; a screwdriver can gouge aluminum). Then repeat; at least once more.
The good news is that a lot of the stuff that relies on vacuum (like the power steering and A/C idle-ups) started working after I cleaned it up!

so I have my intake off again......
looks like some of the passages are plugged shut! What works on this crap? Also is there a way to get the valve to open and close off the truck? I can guess the valve its self is probally gunked shut.....

Try gasket remover or oven cleaner - both good for caked-on carbon if you let it sit long enough. Make sure the stuff doesn't get on any wiring, rubber, plastic etc.

lol. I was actually able to soak the EGR in a jar of parts cleaner, and after a few hours I used a straw from an icee to scoop out the gunky carbon. The Icee straws have those little spoons at the end, and being made of plastic they are able to bend and flex around corners.
