Re: Losing a Bearing or Two or Three?...Ugh
I am seeing a shiny spot deep in the root of the gear, making me think the cam gear is thinner and wearing deeper? Remember these mating surfaces are oil by mist in the bottom end. There is a old timers trick to a better oiling method but don't think thats your issue at this time.
Both mating surfaces are alike or should and the wearing section I would think would be like a ring gear /pinion tooth contact, about the center of the tooth. I had one worse that this, the tooth was worn in half, surprising it did not break.
All said, you have flakes/specks in oil and its concerning as you said they weren't there before start up?
I suggest digging deeper if not pulling the motor and put on stand, start looking at bearings. If you don't find anything, then clean it all up, even take the oil pump apart, keeping the gears matched and wash out.
It would not surprise me if you didn't find anything.
What about the cam wear button or plate? Cam gear to block surface wear? Do you have a rigid timing cover like a billet Cloyes with the hex-adjust bearing cover?
I would bet Big Dave has had a hand in stuff like this, maybe he will chime in.
