What would cause the gear on the oil pump driveshaft to wear? I have a melling hv oil pump and milodon oil pump drive I think part number 21505 made from steel and it says the teeth are heat treated. comp ex295hl cam. There is a real fine metal flake in the oil that is really hard to see I am thinking it is from this and don't think it should have this much wear.
I will post pictures soon.
