[V8] Rear main seal leaking? Uh oh.....

[Carter Johnson]

That is correct - one or the other.  Sorry if I didn't
make that clear.  Obviously, though, with everything
apart, it makes sense to service the tranny.  It is
*likely* the rear main - we replaced all the breather
hoses in the hope that the leak was there when I did
the timing belt.  When you're under the car, if you
peer into the two holes at the bottom of the bell
housing, you can see oil accumulating on the inards. 
Also, a close inspection after a hard run in and 30
minutes running showed no leaks from up high, though
the right bank is noiser (cam chain slack????) and the
right bank distributer is a touch weepy.
