Kindly explain in detail what is, IN your
opinion the best way to fiji small hole
between the cylinder and water jacket, and
above the highest point Of piston travel
It IS best to have the defective part weld
ed You might try cleaning the spot thor
oughly and using smoother cement. This
has often been used to advantage TO re-
pair very small leaks

Why is it that some motor car builders use
aluminium crank cases and others use cast
ference in cost or strength Thanking you
in advance, / remain Curious"
Aluminium is used on account OF It's
lightness- Cast iron is much cheaper. but
weighs considerably mere. Aluminium has
is about One-third lighter. A high grade
aluminium casting is much to be preferred

Although my car is running very we'll /
have noticed lately that when driving on
car tracks with or without the clutch en-
THOUGH one OF the tires were flat or had a
lump on it. The trouble seems to be in the
rear wheels On an ordinary road the JOLT
ing is not noticeable on account OF the IN
eveHness Of the roadbed
VIII YOU kindly state through the col
umns Of the motoring department what
1T is possible that there is high spot
in one Of the differential beTel gears, which,
at each revolution is felt. It is also posi-
bic that some part Of the differentiaf may
be hitting the differential housing in turn
ing This may he caused by a slight end
play in the bearings
You should be able to remedy this by
lacking up both rear wheels and then al
lowing the motor TO drive the wheels slowly
A careful sounding Of the differential and
driving units should locate the trouble.

Recently I have had great deal Of trou-
bic with the valves. At the repair shop
they told me that the exhaust valve springs
need replacing and that because these are
weak the motor did not run right do
not know anything about valve springs eE-
for my car. Is this cOrrect2 Tt was my
impression that these springs could be OBJ
The valve springs must be sufficiently
strong to properly seat the valves at all
times when the cam is not acting on the
litter If the springs are too strong IN
necessary power viii be consumed in lifting
the valve Also If the motor parts are
considerably worn heavy valve springs VIII
tend TO make q very noisy motor. 1~On the
other hand, if the springs are too weak
high engine speeds, and an erratic motor

ing your repairs. but it should not be
difficult matter to obtain the proper springs
without making them.

For some time have had considerable
trouble with the front springs on my car.
The other day another one broke. This is
the fourth front spring I have had put in
during the past three months The spring
seems to be heavy enough and I drive the
car with caution when travelling over rough
roads. have tried different make Of
spring, thinking possibly that the ones I
first obtained were of an inferior grade. Do
you suppose this spring trouble is due to
the way the car is constructors I would
like TO know whether there is any way
can avoid this constant breaking q springs.
Please ADVISE IN your next issue and Oblige.
Reader.
The springs are probably too light for
the weight they have to support. The addi-
ton Of another leaf would undoubtedly
prove advantageous If YOU do not care to
do this would suggest that rubber bumpers
be Installed to relieve the spring from un-
necessary strains in going over bad roads
Care should also be taken to keep the
spring clips tight at all times When a
spring becomes loose at the anchorage point
it Will break very quickly

would like to know if there is any law to
stop the use Of chains or non-skid- devices
of any kind in the state Of New York or
other states; also if the park department
can stop the use Of non-skids in the park
Different states have different laws con
trolling the use OF nOn-slzid devices. The
cities in their respective states also have
ordinances controlling the use Of nOn-skid
devices.
The use Of chains in New York state is
OF amy law restricting their use except in
certain parks. There IS an ordinance re-
stricting the use Of chains on the park
department roads. However. the law is not
generally enforced, since their use is
means Of safety. Chains injure tires, and
no one uses them except when absolutely
necessary.
Motoring Department, The Herald: Could
you tell me about how many miles a 20
horse9ov-er car ought to make on a gallon
OF gasoline when travelling at the rate of
between . TO 80 miles per hour? About
how much gasoline would be used when the
hour with the throttle at the lowest posi-
ton?
Can there be anything wrong with the
car. wheR climbing a hill and running 1t
with the Accelerator, the throttle slips up
about two or three uotches2 What do you
think Of wood alcohol for cleaning out the
cylinders
Is there much difference in the amount
