[V8] Hydraulic System Leaks WAS: RE: Serpentine Belt

[urq]

I had a leak that I swore was coming from the pump but turned out to be the
lower hose to the steering rack.  The thing has a sheath that allows all
leaks to drain to the lowest point, the banjo fitting at the pump.

The only one of my V8's that does not leak Pentosin (or some equivalent) is
the one that has nasty rattly noises from the timing belt or valvetrain and
is awaiting a 4.2 engine swap.  That also happens to be the only one with
working cruise control and a hitch.

If the leak is from the banjo bolt, then try the new o-rings and torque it
properly.  If it is fromt he hose end where the crimp is, try Mobil 1
Synthetic ATF.  In some cases it causes the rubber to swell slightly and
stop or drastically slow the leak.
