Thread: What is normal for material in oil filter

Tweet

Just got a oil filter cutter and cut open my first filter on my drag motor and wondering what is normal or acceptable material? There is no big material but metallic flakes floating in the left over oil draining out of the filter. The magnetic drain plug really had nothing on it. This is a used motor (Guessing between 60-80 passes) with 5 easy passes and a couple of heat cycles on a fresh oil change and new filter. The pictures were taken very close up.

thanks
