Schaltgetriebe / Frage in die Physik ?!

[sparkplug]

Dank Euch beiden.
Aber irgendwie bleibt meine Frage weiter offen.
Ich berufe mich auf dieses Zitat :

The only external venting of a Muncie 4 speed is through the input shaft. If you have a failing output shaft seal ( probably due to the rear housing bushing starting to fail) you will begin to have leakage at the input shaft. There is a oil slinger plate and the front input shaft nut act as guards against allowing gear lube leakage. There are also the 3 shifter shaft input seals, 2 in your side cover and 1 in the rear housing. The seal failure has to be pretty bad before a Muncie will start leaking out the input shaft. Auto gear makes a new style input shaft and throwout bearing collar with a seal on it but stock Muncie 4 speeds rarely have problems if everything is in great condition. Vintage road racers benefit from the Autogear components. I have Auto crossed a M22 equipped C3 for years with no leakage problems from its GM parts. My other thoughts are did someone add a vent to the main case? There is a slight potential that the oil return passage is blocked at the throw out bearing collar or the transmission is grossly overfilled, pretty hard to overfill a Muncie but, I have seen it done before.
