Youth, like everything beautiful, ever passes. So the blue editorial "nine" is approaching a respectable age. A lot fell on the car. In addition to the usual operational runs, she did her best to participate in various tests: on handling and stability, thermal loading and brake system efficiency, vibration loading and smoothness, acceleration dynamics and maximum speed. Moreover, this car is not quite ordinary - from a young age, gas-balloon equipment SAGA-6 was installed on it, which feeds the heart of the car with liquefied gas (see ЗР, 1999, No. 8).
Our "nine" began to grow old slowly. At the next MOT after 60 thousand km, in addition to filters and oil, it was necessary to replace high-voltage wires, spark plugs, wiper blades, headlight hydrocorrector, outside rear-view mirror (it was damaged during automatic washing), side light bulbs and brake light. Installed crankcase protection - not so much to protect against shock, but to protect against dirt and snow flying into the engine compartment. For the same purpose, they put mud flaps into the windows of the steering rods.
By the next MOT - after 75, 000 kilometers - there were more problems. In addition to the usual routine maintenance, we were forced to put in a new rack and pinion steering gear, replace the tie rod ends, the rear wheel hub bearings, the battery and the ignition coil. They also looked into the gearbox, since the noise at idle in its bowels intensified with every thousand. We found that the third synchronizer was added to the “broken” synchronizer of the second transmission. By the same time, the eminent Walker exhaust system began to jingle. It seems that over 45 thousand km of work inside the muffler, the partition burned out. But this trouble can be attributed to the category of minor.
The main thing concerned the engine. And on gas and gas, he began to mope - he worked unsteadily at idle, and lost throttle response under load. In this case, there were no characteristic signs of malfunction of the connecting rod-piston or valve groups. The machine did not smoke, and there was no emission of oil into the air filter. And there was no reason for premature failure - they treated the engine carefully and poured only high-quality oil into it.
Cleaning, flushing and adjusting the carburetor did not produce tangible results. A visual inspection of the camshaft also did not answer the question. They found signs of wear on one of the “exhaust” cams, but it turned out to be harmless. It was alarming that when adjusting the gaps, the exhaust valves were “clamped”, and the compression for engines with the same mileage was not high enough: 1st cylinder - 10.2; 2nd - 11.5; 3rd - 10.5; 4th - 11.2. The operation of the engine improved somewhat after replacing the worn-out high-voltage wires, the Hall sensor and installing a compromise (for gas and gasoline) ignition timing - 6 ° C (it was 2-3).
In the head, meanwhile, stories involuntarily surfaced that when the “eighth” engines are running on liquefied gas, the valve group can fail (due to burnout of the valves). Well, an autopsy will show. Pretty soon - with 100 thousand km of total mileage (73 thousand on gas), it is planned to complete our experiment and disassemble the engine. Of the 85, 000 km of total mileage traveled to date, 58, 600 km were gas.
The equipment installed on the car only once required the preventive adjustment and replacement of the leaking gas valve, apart from, of course, the monthly condensate drain from the low pressure reducer.
The last 30 thousand km on our "nine" are working shock absorbers "Coney-sport". Of course, they are too tough for a "summer residence" car, but for a test car they are quite suitable. The car, although less comfortable, is more unequivocal and pleasant to drive.
It is possible that as it ages, there will be more and more imported components. However, we will try not to forget about domestic manufacturers. Our machine is Russian.
