Hey there— >From the location you describe and the symptoms, it sounds a lot like the >OPV/over-pressure valve to me. This would also explain (possibly) why you >can’t find the leak, since it might only happen when under pressure i.e. when >pulling a shot.
The OPV is located behind the drip tray on the right side—you’ll see a hole, maybe with a paper sticker over it, and behind that hole is the adjustment screw of the OPV. It’s a large bronze or brass flat-head screw. If memory serves, there is an o-rink in there, and if it has cracked slightly (like your group gaskets), it could be letting pressure drop a bit and leaking. You may be able to back the screw all the way out (with the machine cold, of course) and replace the o-ring. Or, you may need to replace the whole thing. I don’t have one here or I’d send a photo and disassemble to see what seals are in there. But it’s a starting point, anyway. Best of luck and keep us posted!
