How much metal dust is commen with a brand new engine. I just heat cycled my new GPX for three runs. On the third run I took it for a couple laps(no crazy revs)and let it cool. Then I let it warm up again and changed the oil when it was hot. I have a magnetic drain plug(which I did not have with the first engine)and it had some metal dust along with some gasket material stuck to it. I know some is normal but there was a glob the size of a small BB,but all dust?
