The Bob, Since it does have bolts (two m 8x20) at the top (rather than studs) if they had made it able to part somewhere in the mid section it does seem that it could be done reasonably with the turbo in place... from the pictures it is not clear how much room, once the two upper bolts are out, you have to move it to a place which would allow it to be raised enough to get the thicker rubber gasket at the pan out.

If I had it out I would sure consider cleanly parting ( tube cutter maybe ) it along a straight section and fabricating a bolt over cover for it which would allow easier removal and replacement. They do appear to have short life times compared to the rest of the things in the engine compartment.

I just had a brain storm.. or at least a thundercloud..... Shrink tubing is available in huge sizes.. certainly big enough to cover this tube... and it can be shrunk with a hot air blower... I have seen leather whip handles attached to the leather using it... and strong does not begin to describe the larger thicker shrink tubing... neat, strong, and heat resistant,,, but could be taken off with a sharp knife at any time to get access to this tube... or it would not have to be used alone.. it could be shrunk down over a shorter piece of metal covering the cut....
