I tried searching, but did not find what I was looking for. Long time reader, new member. I work as a mechanic working on cars, trucks, heavy duty diesel trucks, and heavy equipment. I'm wondering about some of our commonly replaced parts. Such as ignition coils, spark plugs, plug wires, sensors etc. A lot of these get tossed in the trash. I have always separated drums/rotors or blocks for auto cast. I used to throw pads or axles into steel. Recently found out these can be sold to some core buyers. I have turned in alternators at the scrap yard and again found out they are worth more to core buyers. Looking for other areas I am missing or what to do with some more of the commonly replaced parts.
