After changing the caps to work as designed (hold pressure ) the problem is still there on the one drive.. I was really hoping it was going to be that simple.
oh well

Update
 

Got rid of the obviously crappy gear oil I bought one here and put in some Amsoil severe gear and no more aerated oil in the resevoir entire weekend :daz:

This oil was supposed to be the $hit.. its not its crap..do not buy.

One problem down.
Now the other side is always low and I see my extension box is full of gear oil.. loose or busted hose somewhere.. one step forward two steps back ..STANDARD!
