[Healeys] Front Seal - BN1 Gearbox

[David Nock]

There is a vent in the transmission/overdrive. It is in the top of  
the overdrive unit. When they were built new there was a small piece  
of thick paper tubing over the vent and I have had a couple of cars  
over the years that this was still on the overdrive causing a  
pressure build up and a leak.
