I posted pics of my engine bores when I first disassembled it and was reassured that all was completely normal but today I noticed that the mark in the bottom middle of the photo feels rough. It feels like a raised abrasion and not necessarily a recessed or scored roughness but it is tough to tell for certain. However, the rest of the cylinder is completely smooth and then this roughness is quite noticeable.
So, is this the dreaded bore scoring? Or could it be where the oil ring gap has caused a roughness? And is there a solution short of throwing the entire engine in the garbage for either problem? Or is it something else entirely.
Arghhhh....
Second pic is the markings I'm asking about, circled and magnified for clarity.
Engine is a 2000 3.2L, cylinder #2.
