so i started to disassemble my TIII last night and i have noticed a few things

one of the plastic retain clips for the rocker arms fell apart when taking it out. Should i worry about anythign else being missing? When i buy a new one from cindy how do i go abouts installing it??

looking at the rollers of the rockers i noticed that they seem to have some wear on them. Is this normal? how bad can the wear get before i need to replace it? where to i get replacements?

Also when sending for cryo treating and DFLing do i need to take the rocker arms apart?

Also my #1 piston seems to have some damage at the front and rear of the engine! what would cause this and would anyone have 1 stock replacement or a set??

ill post pics in a bit
