long story short, i just bought a low mile engine that has been sitting for nearly 10 years, was removed by the owner and sat in his yard ever since
i pulled the head and didn't turn the engine yet, block looks all good, nice crosshatch, except theres some rust in cylinder 2 how can i clean this off without damaging the bore? really dont want to pull the piston and hone since its only a small spot
