Accord 2018 weird toolmark under engine
 

In the undercarriage, over to the passenger side, just above the screw in the picture, it looks like some metal was shaved off the block.

Has anyone seen this before when you work on your honda? will this cause problem with rust going forward?

I don't see a screw in the pic. But I do see a couple of bolts. Aluminum doesn't rust. It can corrode though.
