Yep, not surprising the gunk that builds up.
I got rid of the oil vapor bottle and so far no more gunk buildup.

Mine too

Thats just what mine looked like before I cleaned it. Mine were running around 220 as well. Cleaned the radiator out, added fresh coolant, along with a new thermostat. Temps haven't been over about 185 or so since then. Worked great. What are your temps running now?

It's amazing how stopped up they get. Mine from the back didn't look bad while installed. Of course you can't see the front side. I removed my catch bottle too and ran the line down into the frame.

I routinely hit mine from the front with a power washer and a wide angle nozzle (3500 PSI, I dont get too close ) and I still wonder what it looks like.

I'm going to pull it eventually, but I havent had a high heat problem.

I did mine last year because it was running hot. It is amazing how dirty they get. Running cool ever since.
