Yah, that's a fun one, & also the reason I've learned to always carry a 22mm stubby in my glove box.
The EGR block supplied with the s/c kit will test your patience because the nut tends to loosen itself...then you get hear what your VX would sound like as a diesel.
I found that a gob of hi-temp silicone on the EGR nut threads upon reassembly works better than loc-tite to keep it from loosening.
