I have a German VW Beetle gearbox (AB Code) that was recently rebuilt as a 4.12.
The box is leaking gearbox oil from the bell housing between the gearbox and engine so I thought there must be a faulty seal.
I have replaced the drive shaft seal twice and the leak is still there. I used an original VW seal the first time and then an Elring seal the second time and nothing seems to work.
I checked that the drive shaft was perfectly smooth (it is) and made sure there was not a groove cut into it from wear. I also cleaned out the area where the seal sits and used Permatex on the outside of the seal and a little gearbox oil on the inside - none of this has worked.
Does anyone have any other ideas of what I can do or check - it's driving me crazy and ruining my drive way!
