227 ppm on 52,000 km
changed oil and filters
21 ppm on 11,000 km
gone from a part of copper every 229 km to 524 km.
I still don't like it. Every single UOA I look at copper is below 1. 1 PPM / 40,000 km or something like that.
Only thing I can do is do another analysis around 30k. If copper is still going up at a regular rate, at this point it is becoming a regular wear metal and we can eliminate anything irregular like gaskets or oil cooler.
At that point, the engine would probably have to come apart.
