Yes but I popped all the plugs for the hot tank and installed new ones but did not pick up on hitting the center to expand. My bad there.

OK, I was asking as maybe if it comes to it, you can clean the area with alcohol or brake cleaner, put some thin sealer around it (like gasket shellac) and punch-expand what is in there now.
