Tach pick up oil leak GS 850

[laajd]

I am posting this to get a little advice from the experts.
Regasketed my 1980 GS850G (Grey Ghost) see the thread in projects if you are intrested.
All the leaks are fixed except the Tach pick up where it comes off of the head above the #3 cylinder.
I put a new o-ring around the outer diameter of the casing but it is stil leaking.......
I tighened very snuggly.
Advice is welcomed.

There is an inner seal also, in addition to the O ring. Unscrew the cable from the adapter and you will see the seal
