Having completed boring my 3 ½" gunmetal slide valve cylinder bore I noticed a slight imperfection in the bore. It doesn't appear too deep. My question is whether I reject it or accept the slight pitting assuming it will not cause any issues later on down the line.

All other marks are felt pen! An experienced eye would be appreciated as I am new to this.

No, that won't cause any problems at all. If you try boring it larger to try and get rid of it there's a good chance that it will get worse. Been there, done that!

Thank you for the reply. Glad you said that as I did not relish having to return the casting and start again!!
