I must've bent 3 or 4 of the Jensen "tools" before making a stronger one  :D

Yep, I was a tad disappointed with the Jensen tool myself. I guess it just kicks me for being lazy- I could've just made one of scrap stock that was much sturdier. Since I was placing an order anyway I thought I'd give it a go.
 Now i have to make one, and still get the nut loose. It is bottomed out enough to push the gasket out...

I made a much sturdier tool than what Jensen supplies and I agree that sometimes further tightening will help free it.

Yes Gil that's what I made as well. One that didn't bend so easily. The supplied one is fine for relatively new engines, but old ones it struggles with.

Well done!

I love it when people make their own tools.

Thanks Dave & Gil - "counterintuivity" for the win!
Tightening a little did the trick. Am gonna put a tiny bit of anti seize on those threads for the reinstall.
I agree the Jensen tool is of little value - it lasted but the first few seconds of this ordeal.
Ended up making an inelegant tool out of 3/32" fence brace that was snug enough to stay put under load.
Would love it if somebody sold a proper tool for this job (hint, hint)!

I had the same problem, tried the same actions without success.  The eventual fix was to further tighten the ring before trying to unscrew it - that worked for me.

Anything I am missing here on unscrewing an extremely stubborn Jensen sightglass ring nut?
Here's what I have tried so far:
-Penetrating Oil
-Descaling solution inside and out
-Heat - bringing boiler to steam
-plenty of torque
-lots of patience and several days of retries
