There are some slight chips on the holes. I Can take pics later

Slight chips are not bad. Chips that will need silicon are ones where the gasket does not have enough completely flat surface area to create a seal. I've made some nasty chips that I wouldn't think would seal, that actually do.

If you make me guess, I'd say if the chip is big enough that at any part of the ring has more than 50% of the width not laying on flat surface, you'll likely have need silicon. I hope that makes sense.

Heed all the advice given. Especially the folded gasket and over tightening.

Remove all the gaskets and the bulkheads and check for cracks in the plastic.
