Engine pull question

you never said it was right after a break-in period Im not sure what is normal but break-in oils have more zinc which is silver in color and heavier than normal oil. I got to say that some minor deburring is to be expected during break-in and the resulting sludge is sure to be metal particle filled and likely more magnetic. is zinc magnetic? Quick Answer. Zinc is generally not a magnetic metal. However, it can be made slightly magnetic when exposed to a very strong magnetic field, but this property immediately dissipates as soon as it is removed from the field.
didnt you say you had some residue on the oil drain plug?
