I have noticed shiny particles in the oil drained from my vacuum pump puke tank every time I drain it, twice a day at the races on my new motor so I decided to look at the gear, it was a new Mopar brand and it is making metal since start up evidently
This motor has a set of Jesel paired shaft rocker arm set up on the 440-1 heads so I don't want it failing, I reused the one out of the old motor that has 5 + years of racing on it with no issues or evidence of wear on it yet
I'll watch it carefully now and hope it doesn't start wearing against this camshaft
