Vertical Cylinder Wall Scratches?

[lostforawhile]

Sandpaper, emory.. whats the difference? I am not english speaker, lija in spanish means something with abrasive properties, and theres lots, so we say lija (sandpaper) in every case. I use the 3M ¿sandpaper? made of some abrasive substance (not sand i believe) & backing cloth. I can assure a very good result in the case explained in this topic, using 150 grit (or more) and oil, then cleaning the hell out off it, OR (much better) the three legged thing with little stones that can be attached to the drill , but i guess that you have more control if you do it manually (sandpaper.. or i should say emory cloth?).
Sorry for the Babilonic Tower confusion

emeory cloth is not sandpaper, they are two different gators

you've probably stopped worrying about this by now but i do agree there's a distinct possibility that you are the Doctor Death of engine rebuilding! when i took my engine apart to get at the cookies inside i found it had a nice crosshatch hone pattern, and i dont recall it having loads of vertical marks, maybe one or two. maybe its not oiling properly / getting washed as you suggested.

my hatch's radiator sprung 99999999 leaks so i had to have it rebuilt but apart from that its ok
