I think the "sparkling" or "flaking" on Cyl1 is significant enough to look into. Cyl3 actually looks quite healthy to my eyes, but again, could be the photo. Looks like there's a little bit of a shadow on Cyl3 tip so it may be hiding the "flaking"/"sparkling".
From the pic though, funny enough, Cyl3 looks the best out of them all.. at least to my eyes. LOL
