of the statement usually make it in
tones which seem to demand exclama-
tions of admiration from those in the
audience. I personally am unable to
make the response demanded.
ITO drive at the speeds necessary
to cover such mileage in one day,
and to remain behind the steering
wheel for the period inevitably re-
quired, hardly seems reasonable. Driv-
ing oneself to endure such fatigue, to
take such chances as are involved,
scarcely seems admirable.
1T would seem that the sound
course with reference to fixing a
mileage schedule that would apply
with equal wisdom to all would be to
stop at that point in the days travels
when fatigue asserts itself in the form
of a loss in driving efficiency. That
point varies, of course, but each driver
is capable of selecting it for himself"
WHEN your automobile tries to tell
you what it needs, do you turn
a deaf ear? Or are you one of those
who are learning how to interpret
its special language Of signs and
noises?
If you are one of those in the
latter category you are certain to
benefit through decreased operating
costs and greatly increased service
from your car, according to Frederick
c. Russell. There is hardly trouble
that is not clearly expressed in the
automobiles own jargon. If this
language Is Greek to the owner he
pays the penalty in terms of what
might be termed service tax"
This tax is usually the difference
between motoring at the usual cost
and motoring with your hand ever
lastingly delving into your pocketbook.
When the car speaks is equally as
important as what it says. For ex-
ample, piston slap always shows up
worse when the engine is cold. Loose
bearings pound at all times, while loose
wrist pins speak out after the car gets
rolling along, especially when it is
rolling freely on level ground or down
a slight grade. If the engine starts
skipping regularly along toward the
top of hill it means that the valve
clearances are not sufficient. As the
engine heats up on the grade the valve
stems expand and the valves fail to
close. This results in the audible skip
and means that the car IS trying to
ask for better tappet adjustment.
Backflring when the car Is climb
ing hill usually means that the spark
plugs are not of the right heat type
Their points become overheated, caus-
ing preignition.
After firing explosions in the ex-
haust and muffler) when the car Is
going downhill may mean several
things, usually that the spark plugs
are missing. This causes unburned
gas vapor to accumulate in the ex-
haust system, then firing so as to cause
an explosion. Readjusting the points,
so as to bring them closer together,
usually will check this trouble. An
over-rich or excessively lean mixture
will also cause after firing, but the
trouble will not be as regular in all
kinds of weather as the kind produced
by missing plugs.
Shrill, continuous squealing under
the hood means that the distributor
cam is very dry. A small pat Of vase
line will cure this.
MOST squeaks in the chassis orig
N mate between the spring leaves,
usually at the front ends of the rear
springs. Double check on this by
spraying the spring ends with pene-
trating oil. This will also serve as the
remedy. A heavier, creaking sound
means that the shackles are not prop
erly fabricated, or that they are too
tight. Worn or old rubber shackles
will make grunting sound. Cure
this by heating the shackles or by re-
placing them, if heat treatment fails
to check the noise.
When the engine is running out of
gas it will give hollow, gasping sound.
A sound like canary bird chirping
when the car is accelerated means that
The cylinder head gasket has sprung
3 leak. Usually the gasket will need
TO be replaced when this trouble be-
gins.
Most motorists seem to believe that
squealing brakes means that the lining
S of poor material or that it has in
some way deteriorated. This, however,
S more likely to be due to lack of
When one brake shoe
comes into engagement before the
others, it vibrates. All noise is based
upon vibration.
The automobile talks fluently by
means Of its own original sign Ian
yuage. The classic example is the
character of the exhaust fumes. Blue |
smoke indicates excessive oil pumping, |
if smoking is noticeable after |
The car has gone down grade or after |
the driver slows down from high speed. |
Black smoke means an over-rich car
ouretor mixture, possibly trouble with
he choke valve. Steam from the ex- |
aauSt, except during the warming up |
period in cold weather, speaks plainly |
10 the owner, telling him that there |
Is gasket leak in the engine.
When the radiator leaks but shows !
no signs of water on the core any me-
,hanic will tell you that the break Is
along the edges and not |
in the core itself. Oil dripping from |
The rear Of the engine, If accompanied |
BY drop in oil pressure, speaks of |
eakage around the worn or loosened |
rear main bearing.
You stand better chance of enjoy |
ing more favorable experience with |
your car if the jargon it speaks is un-
and not Just another for
eign language.
