<VV> Diff Still Blowing Lube Out Vent

That is really odd, I'd have to say. I have an early cover on our
Greenbrier with a 3.89 diff. Gears are turning at least as fast at 65 mph
than your 3.27 is at 75-85 mph. I get a slight amount of seapage, but no
puddles, just enough to attract dirt. Our Ultravan has a 4.11 but I've only
had it up to around 60 mph. We had a problem with gear lube getting pumped
out of the vent but that was my fault. I went with a custom vent design on
the Ultravan that someone else in the Ultravan club used. Didn't work for
me, it actually didn't work at all. Just taking it a mile down the road and
back at highway speeds was enough to loose a 1/4 cup out the breather !!
You can see the vent design that didn't work by looking at my Flicker pics
in the link below my sig line. I ended up sawing off the part of the
breather that extended down into the differential and welded a baffle over
the open hole. Problem completely solved.
I'd have to say that your problem has me stumped!!
1961 Greenbrier Deluxe, 4spd, 3.89 On the Road Again, yeehaw :)
1963 Spyder, restored 4spd Saginaw
1967 Ultravan #299 Newest of the herd!! Almost killed me already!!
A few pictures of the Greenbrier, UltraVan, engine and tranny tear down with
more to come!
> Mine is the newer design: driver's front.
> After a hard highway run, there is gear lube pooled on top of the cover;
the leakage is definitely coming from the vent.
> Any other ideas?
