OCV solenoid replacement, something's a miss

[patriots21]

Hi folks, new guy here, I just finished replacing my OCV solenoid on my 2006 toyota vios, it's practically a sedan yaris which they market in southeast asia. Did this after I had my engine diagnosed following a check engine light. I managed to do it without much problem but I noticed something that I'm not so sure what to think of. After removing the OCV solenoid, I looked into the opening on the assembly and it looked to me that there's a piece of the base of the opening that has been chipped-off. It could of course be just be the way it is, i'd like to think so, but would like to hear some opinions. I've attached some images I took before replacing the new solenoid and a picture of the end of the old solenoid I took out.

It's a 2NZ-FE 1.3L engine.

Thanks.
