Thanks for the response!
If the smell is in the bathroom....it would need to enter the room from under the floor. My thought would be removing the toilet would still be the first step in removing the tank. And it would allow you to check the connection between the flange and the tank. The tops of these tanks is rarely flat so a leak could be anywhere on top. If (fingers crossed) it happened to be cracked or separated there, it could possibly be repaired/sealed maybe without removing the tank.
Nothing to lose.
It not there then it could be the vent connection to the tank. It may be cracked or never sealed/glued in the first place.
I guess I'm just hoping it's an easy fix.
