rusty valve covers September 03, 2022, 01:51:37 PM in our cars are some rusty valve cover.some with a even layer of rust, some with the rust peeling off.what to do about it ?pitting corrosion should be avoided, i guess ?should i use a wire brush or apply rust converter ?maybe removing the oil with cleaning alcohol before ?after having it off, one of you guys brushed it cleanand painted it black with something, i have seen somewhere here.but since i wouldn't take it off now, i just like to conserve it a little..
