Don't waste your time with a medical stethoscope - the design of the
bells is different, so as to make them useful for listening to
widespread sounds from squishy things. If you're after mechanical noise,
get a mechanic's stethoscope with a rigid probe connected to a diaphram.

How much are those?

I've found a cheap medical type far better than the tube method and less
dangerous and as effictive as the screwdriver trick.

Expensive! Mine came from the usual route (mil-surpus from Anchor)

You can improvise though. The screwdriver in the ear is effective, if
inconvenient in layout. You can make all sorts of lashups with two
tincans and a length of string, then work up from there.

I really don't want the possibility of the handle whacking me in the ear
when working on cars. My cheap medical stethoscope works fine for finding
car noises.
