Rust concern
 

Hey ive been taking apart my engine to replace the head gasket but now that the cylenders are exposed i worrie about rust, im not sure will it rust quick if exposed to air or is it not steel, im not sure.

The reason is that the head gasket set i ordered was the wrong one so i have to get another.

if the cylinders are exposed they will build a layer of rust. either keep them oiled, or just wipe the rust off. you should be able to wipe it off because the walls should still be oily.

Thank, i was reading up and its aluminum (however its spelt) and well aluminum doesnt rust, but steel does.
