So far my "Freeze Plugs" are bone dry using the M7 bolt and washer, so it looks like this is permanent repair.

Another member emailed me: he mentioned that he tried to remove the "Freeze Plugs" to thread an NPT plug, but in the process of removing the "Freeze Plugs", the Housing hole is damaged, so he could not make new threads. He ended buying a brand new O. F. Housing.

So for those who want to remove the "Freeze Plugs" to tap new threads, I know it has been done before, but beware!
