Scratch on block surface

[BreckAConner]

Good Evening,

I was wondering if this scratch is acceptable? It was catching with my finger nail but I lightly took the wire wheel and got the bur off. Let me know what I need to do or if it's fine. I just got it back from the machine shop, not sure how I got the scratch on there.

if it were me, i would clean it with alcohol and put a TINY bit of High-Heat Copper RTV silicone along the scratch while im installing the headgasket, carefully skimmed smooth with a fresh razorblade.

reasoning: the scratch is tiny, and only within the cooling jacket, not crossing into the combustion chamber. some copper silicone should seal that up to keep water from squeezing through.

Thanks mike, I'll give that a try when it comes time. I was kind of freaking out and wasn't sure if it needed milled again..
