Injector cup seal

[S3 Hilife]

Hi guys, after being down on power and boost I've just smoke tested my engine to find injector #1 leaking from the cup/seat.
Before I strip it down and attempt to remove the seat to repair it what's the best method to re seal it or is it an O ring that seals it? I've never needed to remove the injector seats before

Are the threads supposed to be wrapped or coated for these to seal properly?

As std no but I used a little sealant when I fitted mine... considering the boost etc its worth while...

Be very careful doing them up again though... they can split if you over tighten

Thanks mate, when you say sealant do you mean silicone?
