yeah thats why i didnt post a pic of what i saw. but i was looking at it and felt it and it was for sure metal

I tried to get some pictures with little luck thanks to the terrible location of the uppipe and EGR.

wel, i tried to do the egr plate today and for the life of me, i could not get those damn nut loose, i tried for probably 45 minutes and could not break them loose! i was using a 7-8 inch gearwrench ratchet wrench and just couldnt do it. i never tried the bottom nut bc i couldnt get the rea one loose. i was so pi$$ed and still am. i am going to call jeff dean tommorow to see if he has ne pointers or how much to do it.

i tried connecting 2 wrenches and there wasnt enough room to do it.

did you go through the inner fenderwell then to break them loose? i had the fenderwell out and really couldnt even see the darn nuts.

Moving blanket or other thick blanket
2 Stubby flat blade screw drivers..I like the craftsman ones
1 12mm ratcheting wrench
1 14mm stubby open end wrench
Tin snips/hack saw/band saw

First thing to start with is removing the intake elbow from the filter box and the turbo inlet tube and set it aside. Then remove the silencer (large plastic box with the 6.6 on it) it's clamped on the underside to the turbo inlet tube and fastened in the front by a torx fastener. Now, lay the blanket over the air box and the engine bay on the passenger side up to the turbo inlet....this makes working back there ten times better. The EGR pieces you're looking for are located almost at the firewall on the passenger side of the compartment. Remove the small sensor that is screwed into the engine side of the EGR piece and move it out of the way...this will take a 14mm open end wrench. You now have as much access as you're going to get and this is where the 12mm ratcheting wrench will be your best friend. Loosen the 2 12mm nuts holding the EGR mating surfaces together...they face the firewall and are offset from one and other passenger side lower than the driver side. THEY ARE VERY TIGHT !!! You may need to link another box end wrench on your ratcheting wrench to get enough leverage to get them off...be persistent. Now the fun part...with both nuts fully removed wedge one stubby screwdriver at the top of the mating surface and pry like your life depends on it...mine was exceptionally tight. (Make sure the gasket is on the firewall side mating surface) Once you have the parts separated take the other screwdriver and wedge it in on the outside of the driver side bolt sideways. Keep working the two screwdrivers until you can get the sideways screwdriver pushed in almost almost all the way down the blade...trust me it will stay in place. Take the EGR block off plate you purchase from your retailer...I used the one from Meyer performance...and snip the ears off the far side of each plate. It should wind up looking like it's got a hook on either side where the stud will locate it...I trimmed mine like this so you can leave the screwdriver in place while you drop the plate it. Wiggle the plate into position...at this point my plate just about fell into place. Reassemble everything in reverse...don't forget that little sensor you just removed...and you should be EGR deleted. My first attempt at installing the plate took me forever...I just did a buddies truck and it took me 20 minutes start to finish...GOOD LUCK !!!!

nice job ..man
