Removed it and double checked to see if the flange had compressed shut. A few did and I just used a small drill bit to open it up.
Didn't think of doing this... but no problems with bleeding the brakes, so I guess that means none of em were
completely compressed shut.
Sorted out a fuel leak, got the emissions down (from 8%!

), and took out the rear seats, then drove to the MOT station for sill-welding, a new exhaust hangar, and a retest.
Got my green sheet, so I'm happy

. Was intrigued to see that the station had failed the lack of rear exhaust hangar (I just had a jubilee clip). I thought they were going to weld a new one on for me, but they just put a couple of cable ties on!!
