Thread: rusty cylinder

i left my sr out in the rain last night.it was covered but a little water got into the cylinder walls and some rust appeared. my question is should i be concerned about that little amount of rust or just use a rag and some steel wool and clean it???? thanks in advance

I wouldnt do that, scorch the walls and lose compression. Im guessing this is the bottom end with no head that you left out?

use a rag to clean off the surface rust, then hone it. Don't take the risk with steel wool.

30 grit sandpaper FTW

lollllllllll

30 grit sand paper it is then

30 grit sandpaper will look like gravel!! The lower the number, the coarser the paper. Someone is trying to be funny . . . . .

Any sandpaper will be too coarse. A light hone with oil sounds best. If that is not available, there is a product called crocus cloth which is a cloth backed abrasive in the emery cloth family that is extremely fine. Or, you could try a chemical rust remover (not a rust converter). This must be used with care, since they are usually acid based.

Exposed metal will rust even without rain because of the humidity in the air. If you must leave the engine (or crank or cams) out in the open for a time, you should wipe it down with oil to give it some protection.

hey thanks old guy kudos to u for being very helpful
