Hotsauce,
dont think I could get a wrech on it well enough to use a mallet. But thats good to know about the locktite.

Mbeach,
I think the EGR block was machined by Nazrat before I bought it if I remember correctly, and it seems to do very good if I could just get it tightened up. Its not vibrating excessively or anything and both other ends seem tight, its a matter of getting to it I think, also mine is s/c'd so that may make the intake tube you mentioned a little different. A stubby may work, will have to take another look, is it definately a 22mm? Its hard for me to even get good a solid grip on the nut with regular length wrenches.

here are some pics of mine, I am pretty sure the upper pipe wont be a problem. The lower pipe looks like it would follow through if the bracket on the back valve cover bolt was removed. I will try the stubby first though, will have to go buy one lol. I think I have everything else but what I need.
