Sniffle Valve Removal

[BillyT0020]

Does anyone have a trick to remove the sniffle valve w/o displacing the exhaust or dropping the lower cowl?

 

I’m on version 3.0 of a long right angle 7/16th wrench I welded up but it’s proving difficult to get it just right with having to take it home to make changes.

Next attempt I might try spinning a nut on the flare side to break torque on from the other end (rear of engine). 
 

TIA

Drop the exhaust and find someone with tiny hands. I cleaned mine at my last annual and it was pretty gunked up.

Yeah I ended up dropping the exhaust, and the lower cowl to replace with the new style Lycoming Valve. Now its easily removable if I need to clean the new one.
