Poulan 2175 Leaks Chain Oil

Another post about a problematic Poulan chainsaw. Here goes...

My Poulan 2175 "50th Anniversary" chainsaw leaks chain oil at a prodigious rate, running or not. Clearly this is a symptom of a worn seal, gasket, o-ring, hose connection, or similar. I confirmed that the notoriously leaky o-ring on the oil filler cap is NOT the source. I believe I found the general source of the oil leak, though not the exact source of it.

I scoped the inside of the tank and determining all appeared well within. Then I filled the oil compartment and added a few drops of oil-compatible fluorescent dye, and let the thing sit clutch-side down without starting it for 15mins... plenty enough time for this thing to leak. Sure enough, a puddle materialized after just a few minutes.
 
Here's the result under the blacklight and a UV filter on camera. It's pretty obvious the oil--which glows white in the image below--is pooling around the seal block (oem p/n: 530019206). There is zero oil seepage around the oil pickup elbow or the oil pump (beneath the clutch).
 
I suspect the leak is with the seal block proper, or the fittings on either side of it. I'll replace that $5 part and hope that solves the problem.
