Leaking Glow Plugs

So once I got the returns all sealed and not leaking I have decided to address the next leak I see.
Several of the injector valleys would fill with fuel and when the engine was tunnng i could see significant air loss through the GP mounting threads.
Is it the concensus that these should be replaced, try to torque them domn or just leave it,

I really don't want to just leave it, I hate leaks.

Opinions please,

I'd try tightening the up a little. If they are working Motorcraft plugs, I don't see the need to replace them.

The glow plugs may not have been tightened correctly and the heat cycles have loosened then snug them down and that should fix it.

I am not sure of the brand, I think I will pull one out and inspect it.
Is there anyway to identify the brand of the plug?

Brand will be written on the plug it self.

If you don't know what's in there, it would be wise to pull all of them out, and inspect all of them, and bench test them all directly on a battery.

If they are motor craft they should say beru just above the threads. Any other brand should say what they are in that location also.

All of the images I have show the branding below the threads.
Mine have a stamp on the hex portion of the GP but I am too damn old to read what is says!
