Oil Leak Continental 470

[Cappy]

I know very little about Aviation Motors. Oil leaking from this part...any assistance would be appreciated..

 

[Cappy]

I learned it was an old Tach Drive that isn't used anymore..I read this was not under pressure but I can tell you the oil was a fine mist on the back of my seat console and it wasn't just a drop...

Any ideas..O Ring ?

Hello, Could you just remove the tach drive unit and plug the opening? Not a AV guy here...

The drive pictured is a reversing unit attached to the tach drive, there is a seal in the tach drive which is the culprit.

Replaced seal and no leak...Much appreciated Sir.
