Engine Overview and Common Failures
The weight of the VAZ 11194 engine according to the catalogue is 112 kg. The most well-known problem with this power unit is high oil consumption. The most effective way to eliminate oil consumption is to replace the pistons. Fluctuating RPM. Fluctuating engine RPM is usually caused by a malfunction of one of the sensors, typically those indicating the position of the crankshaft and throttle valve or the MAF sensor. Timing belt failure. It is crucial to closely monitor the condition of the timing belt, rollers, and water pump. If suspicious noises, knocking, or coolant leaks appear, it is better not to delay their replacement, otherwise major repairs will be inevitable in the near future. Stalling. Sometimes the car suddenly stalls at idle or even when shifting gears, and the usual cause of this is throttle valve contamination, less frequently related to issues with the EGR system. Minor problems. All minor engine problems can be summarized together. Issues with insufficient heating or overheating are almost always related to the thermostat, tapping noises under the hood are usually caused by hydraulic lifters, and engine misfire most commonly occurs due to faulty spark plugs or ignition coils.
