[V8] 91 V8 5 spd - Intake air leaks

[Kneale Brownson]

If the crankcase ventilation hoses are failing (they get all mushy and
start leaking), you normally get some oil dripping onto hot exhaust headers
to tell you they're going bad.  There are three crankcase vent hoses, one
up the back of the engine that vents the crankcase into the driver side
valve cover, one across the back of the engine that links the two valve
covers and one tucked into the front that hooks into the air intake.  The
first two have a molded lip that engages a retainer where they plug onto
pipes so you don't need any hoseclamps.  Some folks don't like paying the
Audi premium for that design feature so they've used other hose materials
and either clamps or zip ties.  The front one gets clamps that you can't
install unless you take off the throttle body and intake manifold.  The
that molded hose seems to stay put pretty well without clamping.
