[s-cars] Knocking developed while on highway.

[calvinlc at earthlink.net]

Does it knock if it is just idling?  If so, does it sound louder when the
engine is given gas in neutral or does it sound louder as the engine is
decelerating in neutral?  Does it sound like it is coming from the lower end
of the engine block or the upper end around the cylinder head?  What I am
trying to determine is if it is a rod bearing knocking.

    Does the knocking change with engine speed?

    Need some help guys.  As I was driving home from work in my '95 S6, I
    noticed a slight miss/hesitation for 1 second which was quickly followed
by
    knocking from the engine cabin. I immediately pulled over and gave it a
good
    listen to make sure of the source, and it does indeed seem to be coming
from
    within the engine.  I also noticed the turbo inlet hose has tore off
(the
    hose that goes from the intake to the turbo).  Car was driving perfectly
    before hand, and always had regular oil changes.  Oil level is perfect,
no
    smoke out the tailpipe.  What the heck could have happened here?!?
