Copper in the oil was created by tonygarrett
I have a 100 hp 912. It has run great for 600 hours. I do an oil analysis at every oil change. The copper (and all other elements) concentration has remained the same for about 500 hours. Suddenly the copper concentration has jumped up about 15% for the last two oil changes. I do the oil change after the same number hours each time. The engine still runs great. No noticeable changes. Where could the copper be coming from? What part in the engine is made out of copper?

Copper would be found in bearings or gearbox components. If you have 600 hrs on engine, it's the normal time to readjust gearbox. Ronnie Smith at Southern Mississippi Rotax does these for ~$500 and does good work.

Hi Tony,
We have the exact same issue now with our 912 engine at exactly 600 hrs.
Can you please say what was the problem and how did you solved it. How many hrs did you do since.?

Thanks for your reply

Oshry.
