I changed my oil and decided to remove the inspection cover. It was glued on with some type of black silicone so I had to pry it off. I found these in the dip area and wondered if I should be worried or is this just left over from when the crank, main, and cam bearings were fitted.
The Cam is showing very little wear so I am thinking it may be a new or regrind does anyone know the significance of the red and white stripes on the cam?
If that looks like babbit, you need to inspect carefully the bearings to see if any of it has cracked off. The usual place to crack which would drop into the crankcase would be on the thrust surfaces. If it looks like aluminum or steel, it could be parts of the timing gears. It is not very likely that the pistons would break and leave particles. If one breaks it will usually shatter and the engine misfire and knock.
I don't know the significance of the stripes on the cam. Might have been a manufacturer or grinders trademark.
I had a 76 Ford with a 300 6 loose bits of piston once, I put several thousand miles on it before I got around to replacing the engine. When I did, I removed three bits of piston the size of a quarter from the pan as well as many smaller bits. Pistons can come apart with out causing a misfire, it did make a bit of noise though,
