GUS are III use TOF dispensing WITH Iue
four coils used in a Ford. / find the car
totherwsie Q. K, but the four coils
cannot be made to give equal sparks
thus giving unequal firing..L. o. D.
You can use a master vibrator coil
such as the New York or better still a
Splitdorf Ford type magnetic. The
magnetic on the Ford then is thrown
out of use and you may employ it for
auxiliary lighting.
Dear Barney Oldfield: In q previous
article you stated that the pistons of
an engine travel faster when nearing
the top than they do when passing or
just leaving the top center. What
causes this and can you prove it with
out a lot of mathematics M. G. E.
The difference In piston speeds at
different positions is due to connecting
rod angularity. 1t can easily be
proved but / fear 1 cannot do it with
out a diagram. I am sending this and
the explanation to you by mail.
Dear Barney Oldfie1d: I have a
brand new car and it Kisses through
the breather. | took it to the dealer
and he said the kissing would go away
claiming that it is caused by the rings
not being fully Tapped in. Since there
is misfiring of the engine on a pickup
am inclined to believe it is caused by
the kissing. What is your explana-
TOMB. C. L.
This kissing is technically known as
a blow-by and may be caused by poorly
seating rings, rings with too much or
two little end clearance, a bad cylinder
block with too much metal at one spot,
a hole In a piston, etc. Without doubt
the blow-by causes the misfiring by
reducing compression to a great ex-
at the end of 300 miles. ask the dealer
to fit new rings and tell him YOU will
not accept the engine until the blow-by
disappears.
Dear Barney Oldfield: A friend Of
mine and myself had an argument
abuot the exhaust of a popular eight
cylinder car. / said that water was
coming out and ] could see it. lie said
it was gasoline that did not burn. The
water or gasoline could be seen 1T the
end of the muffler tailpipe which was
all wet.-F. II. n.
In all probability what you saw was
water though some gasoline may have
been present. In cold weather quite a
lot of water is thrown down in the
explosion and this passes out as steam.
The steam condenses on the way or in
the muffler. In some cases as Iuuch
as two quarts per month may be pro-
duced.
Dear Barney Oldfield: I am hay-
ing a little trouble in locating a knock
in my car which is only about four
months old. 1t can't be from the
piston, no from the valves. Some
one told me it comes from the crank
case. When / put my foot on the
clutch it does not knock. d. Y.
1t is almost impossible for me to
tell you much about the knock because
you give me little information about
the nature of the sound, or the speed
with which it occurs. In an engine
four months old | would not suspect
ANYTHING more than q rocker arm with
a little side play or something equally
as trivial. Be sure that every chassis
part is lubircated according to in
structions .
Dear Barney Oldfield: I am very
much interested in reading your week
ly articles. | nave used my car two
years and have driven about $500
niles Before it is warmed up the
engine knocks, but after the car is
driven a few miles it stops.
Some time ago / left the drain plug
loose and all the water ran out. !
did not discover this until / had
driven about three or four miles. Do
you think that is the cause of the
knocking now before it is warmed up?
7 am told that if oil is forced I'D in
the sleeves by running the engine the
knock will stop. is this true? VIII
you kindly tell me what to do to
stop this knocking?-F. II. III.
In cold weather any engine is like
ly to be noisy. until the parts are
thoroughly warm. 1t is cutie posi-
BILE that your running without water
for four miles wore the sleeves a lit
tie. but then if YOU had sufficient oil
the wear would be negligible. The
%slapping or knocking as you call it is
a result of parts that are a little
loose. a result Of contraction Of the
metal due to temperature decrease.
/ would not worry about the condi-
ton because an engine should be |
judged by its actions when at normal
heat.
