Modify Island Sink Loop Vent

I have an odd looking loop vent under this sink. This one loops back to itself instead of going to a separate run and to the wall for proper venting.

I have to modify the loop vent due to new granite installation. Just looking for some feedback and opinions before I start cutting this thing.

Thanks
Ken

That's pretty funny. No, not a proper loop vent. If you can't/won't correct the venting side by running it to a dedicated vent line, consider an AAV.

I'm an amateur - this is not my day job Not about to try to connect this thing to the wall vent - that should have been done 30 years ago by the builder!

What is an AAV?

For the record there have been no know issues with the operation of the sink and drain.
