Hi everyone, I recently picked up this 2007 Silvia for $25 due to a leak around the boiler. From initial inspection, I didn't find any cracks but did notice the threads were stripped.

After tapping new threads, installing a new gasket, and using new stainless screws, all screws except one thread and seat with no issue. The one pictured is causing a gap which I imagine is causing the leak. Could it be that water possibly froze here and warped the brass, and is there a solution for this?

Any help is greatly appreciated!

UPDATE: I reached out to a friend of mine who is a machinist and has a mill. We're going to try and flatten it that way.
