They may be strong enough to put pressure on the new washer and eliminate the leak.

If not, you will need to find a way to seal that hole and use the new-gen system.
You could try a helicoil but the problem is that the threads need to be perfectly perpendicular to the flat sealing surface in order to avoid any leak.
Thank you, time is what is killing me right now because I don't quite have all the time in the world for my bike to be disabled. Friends have been advising me about the helicoil route.
