This CTSW has had high oil temps for the last 6 years. I sent the oil cooler to Hot Flush and after a bunch of metal this cheesy material started coming loose.

What is it?

Looks like the result of water vapor distilling, for lack of a better description, out the parafins in the oil base stock and then baked hard. Used to happen all the time with Pennzoil back in the day.

  I have no idea what it is, but save it and weigh it on a fine scale- like a reloading scale.  Then when you find out what it is, you can weigh the new part and find out how much might still be in there. I once had some red plastic like that clog up a hydraulic system. It turned out to be part of a sight indicator on the oil filter. It had cracked, and somebody pushed the red indicator back into the hole, and screwed a plug in on top of it. The pump chewed it up, and it jammed the hydraulic system valves. We kept cleaning the system, saving parts and weighing them, and comparing against a new part.

Did you know that many drones are powered by a Rotax engine?
