OP ELIMINATING VALVE ; NOISE. ' : There II 'nothing so important as correct clearance . between valve tappet and valve'stem for good all around motor per form a nee.- Frequently the car owner permits slight valve noises to get on his nerves,, loses his : patience, .then drops Into the fir3t wayside Hospital and asks the first man he xneets to adjust his taprets, which in about nine cases out of ten Is the. wrong thing to do. It usual ly .results In a quiet tappet for the time being, but causes a lot of other complications that end up with expensive repairs. ; v Owing to slight variations in cam -designs, length of valves, and .other conditions too, technical for th? average owner to understand, correct tappet clearance varies in different makes of .cars. There fore, It, Is always best to go to the direct representatives of manu facturer or to men specializing In service on your particular make of car when y.du think your valves meed attention., . . ii , -' : Frequently, 4 the manufacturer specifies a different clearance on Intake and exhaust .valves in some cases the same clearance for both, but in either case !t I3 absolutely necessary that' their, specifications be 'adhered to closely. Closer set-. tings than ' specified with some cam design will ' result in . thej yalyes being - partially, oren; very I early on the lift side and. very late on the closing side. One condi tion affects carburetion material ly,' while the other causes a loss of pover "also burning and warping of exhaust valve. - Other complications resulting from setting the valves too close are plugs foulinf valves sticking In their guides, the scoring of tap pet rollers and the flat face of mushroom type tappets. Irregular firing "of cylinders, ' bucking and back lash noises at low speed, ra pid accumulation of carbon in combustion chamber, exhaust smoking and. a lot ofother condi tions too numerous- to mention: and in the end valves that are set too closejy usually develop incura ble noises as a result of scoring, requiring replacement. The above symptoms are often diagnosed as ring and piston trou- ' ble because the weak compres sion resulting causes combustion chamber, to become wet with oil as though thoN pistons were pass ing oil, and the irregular firing of motor causes knocks and slap ping sounds, that , are often mis taken for loose piston. S When these symptoms develop in your car particularly new cars, and .on older cars immediately after the valves have been tam pered with, it Is always best to have a good, service man, one that specializes on. your ; particular make of car, to; check your Valve settings, ignition timing, carbur etor and choker adjustment, be fore allowing, anyone to condemn your pistons as being too loose or your rings as worn out. .' .. To show 'how easily an owner or even a dealer's service depart men t can go wrong on this, I was called upon a few years ago by a big eastern dealer to examine five new model cars which he had just unloaded and declared the poor est running automobiles he had ever received. In this particular case, it happened that I had per sonally . checked these five auto mobiles, they being the ; first of the new models to come through production. ! . I was particularly anxious to observe the ' improve ment over previous models there fore, before cars had been shipped from the plant, I saw their motors pull 10 pounds more on the Dyna mometer Test than the old model, throttle down two miles , an hour slower than the old model In fact, I, was quite enthused with their general all f around goodness, so much so, that , wSen this . man's S. r C S. came to my desk, I was bound and determined to find out, what was wrong with his organ ization. soJ I 'delegated myself to investigate the matter..; i : First of all. we tried each car out separately. They were just as - bad as he , had reported, no power, : exhaust smoking, motors fired Irregular and cars would not throttle below ten miles per hour without' bucking and blacklash noises. ; . Somebody had thrown a monkey .wrench in the machinery sure enough, but It did not take long to find out how it all came about. It happened that his ser vice, manager had' just started a new system of inspecting and turning new : cars before deliver ing J them to customers. , These five, cars had gone through ' the hands of two hew men" who were not ' familiar With correct tappet clearances and Ignition i timing specified by manufacturer.; . Be cause the valves appeared . noisy when the motors were started up. which Is perfectly' natural e" ? standing idle two weeks In fre' car wmie in transit, tney naa. the valves up too close.- This ruined the mixture and" motors would not throttle down and in an effort to make them throttle they bad adjusted ignition timing! too late, naturally with these two conditions a correct carburetor adjustment could nat be obtained. However, after setting the above Item In accordance ' with manu facturers specifications, then . al lowing the motors to run at 1000 revolutions for three hours with a little surplus oil, tnese motors worked in nicely and : made a wonderful demonstration. The dealer enthused so much over their, performance, that he wired an order in for five more car loads. He also called ; a - little friendly meeting that night for the benefit of his service organi zation and every man knew the manufacturer's timing standards before he went home, also was supplied with an extra instruction book where all of this informa tion can be found. Always re member if the valve tappet is not quiet when set within the limits specified by maker, something else is wrong, slightly, noisy tappets as a rule do no harm. It is better to worry along for awhile for they come and go, sometimes for no reason whatever. At times valve noises are affected by low oil level in crankcase or by oil thinning out and again when car is out of service for several days due to oil film - drying up or draining back to case.' Consider all of - these points before trusting the adjust ing, to strange mechanics. 4' - -' 1 Excessive Oil "Consumption On several occasions I .have heard car owners complaining that their oil mileage "was entire ly too How.; Analyzing some of these complaints a few were found justified, but - in the majority of eases, to the contrary. ' i - - Opinions vary widely as to what Is considered - a fair average ' per gallon of oil, also fuel confmp-; clearances between valves and stems, worn piston rings, oil pass ing through front or rear bearing, leaking head gaskets or oil line connections, and , several other points, that will be covered In de tall later. Now, first of all,' we must de termine what is considered a fair average per gallon of oil. In do ing this, we must take Into con slderation the kind of service a car is subjected to: , --Under average city running conditions or speeds up to 25 miles per hour in the writer's opinion, S00 miles per gallon Is a safe standard for maximum eeon omy. ' If the oil level in your mo tor registers full after this dis tance, motor should be drained and refilled with new"!!.' The fact that oil level doessnot recede In 800 or'1000 miles Is not always the sign, of an oil tight mo tor. There is always a certain amount of crankcase dilution Wik ing place (gasoline passing pis tons.) In some cases a slight waste through leakage at some point or the amount motor actu ally consumed is offset by the amount of dilution occurring thus keeping the level up In crankcase, and it Is not uncommon for the amount of dilution to exceed what is wasted through leakage and quantity of oil actually consumed In the running of motor. In this case, the level in crankcase would increase and your supposed to be. lubricant might consist of half gasoline and oil - - Tests to determine extent of di lution under various running con ditions prove that as much as gill of gasoline can pass the pis tons into crankcase when mixture is not right during one start in cold weather. Road tests show that dilution can run as high as 45 per cent under the worse condi tions that, is under city running conditions where a motor is sop-t ped and started frequently after short runs, as in ' the case of a physician making his calls or salesmen calling on the trade.. The only way you can determine the quality of the oil . In your crankcase after a period of several hundred miles, is to have an un biased chemist analyze It. In a tion varies Wiriolv In the A it tar. ent makes of cars, because Wnel' "- the oil might show a deaienor. v lalr test, but in nine cases out of ten your motor will benefit by a fresh charge of oil. Beware of false economy. designers have made closer study of controlling the oil at the sev eral critical points, where wasts usually occurs, but even then, there is danger of leakage, if work manship and inspection-is not 100 per cent.' for a slight. leak at a gas ket joint or a screw loose is very liable to cause sufficient loss to cut your oil consumption In half Other ; conditions contributing to wasts of oil are improper mix tures diluting the oil.

CARS 'TRUCKS j k i 1 y . : XXIACTOIVS ..1 Under touring conditions 30 to 40 miles per hour, the oil is churned more violently by the higher motor speeds, and due "to higher motor temperatures, the oil Is thinned out more, therefore, the loss In vapor, through the crank case vent would be greater and leakage ' may develop .through other joints which would not show when the oil is mWe ous "at lower temperatures, furtherm'ofl? oil is burned up so it would te un reasonable to expect . the same economy under all running condi tions. , .,. ;::T: If you have been accustomed to city Tunning with your car, par ticular attention should be given to crankcase oil on your first day out when touring or until you have formed an acquaintance with its characteristics at higher speeds. Oil performance is liable to vary greatly at high speeds even in a given make of car, frequently mo tor bearings are burnt out or ex cessive wear develops which can not be perceived at the moment. through ' owners expecting the same economy ; of ; oil ; at , high speeds. 'f, j -v.i s;v"v i fr'-.'.:,''" In order to avoid the above dan ders, always start with full crank- ease and examine your oil level after the lirstlOO miles. This will give you a line on what to expect In the , way of economy, after which always look at your oil level when filling with gaso line. This latter precaution ob viates the danger of running out of oil due to Blow leaks which are liable to develop through a' screw or oil line connection jarring loose.- Unless some special device Is at tached to a motor for distillating or clarifying , the cylinder ',oil, crankcase should be drained, if oil level remains constant arter 50O miles of driving. However. if level goes down sufficiently af ter J60 miles to take a quart of fresh oil, crankcase need only fce drained every 1500 miles. Do not wait for level to go down one-half or three-quarters before adding fresh oil.- . ' Some authorities may differ 200 miles' on the above figures, and enthusiastic salesmen" frequently sell cars on the strength r Its ability to go 1000 or 2000 miles on a gallon of oil. However. If you could personally see the anal ysis report on oil "used' 500 to 1000 miles, common sense would prompt you to never try for more than 1000 miles per gallon under normale city,: running conditions. : Another point to remember in connection with standard passen ger cars is, neveferun for any great length of time M sustained maxi- ' mum speeds. as when racing. les sen ger cars are not designed to do this, r ordinarily bearingsf piston and" rings i require different fits to allow, for expansion and more lubrication, and as a rule wHen a manufacturer enters his" product as standard stock in a contest re quiring wide ; open . throttle,, it MAY, be -stock 60 far as parts iarc concerned, but he always finds It necessary to alter clearances,: hop the oil pressures, or add an aux iliary on system.

(by mail. ) when a German ' has fault t to find with the service rendered him by some public official, f he must be very careful about threat ening to report the delinquent of ficial to higher officials. rlThat constitutes threatening an official and is punishable under .Che Ger man law. It ranks with bribery, or: attempted bribery. A disgruntled Berliner who did not like the way a post official carried out his work threatened to : make ; a report . t6' the control if the methods were not changed. This was reported by the official who objected to the action of the. patron. The lower court held tha patron had violated, the -law anJ the supreme court of Germany has sustained the decision. The court explained to the con victed man that he has the right to make any report he desires to the head of a department whose service 'displeases him. ' He njay also report to the reichstag. But he must not tell the employe with whom he has trouble that he will make such reports unless the ser vice is changed. - Theological Students To Convene in Indiana INDIANAPOLIS, Doc. 22.- Students from approximately, one thousand theological seminaries and collages throughout the Unit Pd States and Canada will be here this month-cpd for the biennial couvntion of the Student Volun teer movement.
