Engine Overview and Common Failures
The weight of the VAZ 11183 engine according to the catalog is 112 kg. Knocking in the engine is generally loud when cold, similar to a diesel, and is not considered a malfunction. It is a characteristic of the engine. Unadjusted valves also cause noise and knocking. But if it's not when cold or the valves, then it is a serious issue and should be taken to a service center.
Overheating: The thermostat constantly breaks. Sometimes you replace it, and then the engine doesn't heat up again. The quality of domestic parts can be very low and there are essentially no alternatives.
Stalling: If your Lada suddenly stalls while driving, every experienced driver knows that most likely the mass airflow sensor has failed and needs to be replaced.
Leaks: Oil leaks regularly occur, even in brand new cars. It mainly seeps from gaskets and seals, as well as from under the valve cover.
Electrical problems: The VAZ ECU part number 11183 1411020 52 is probably known by heart to every seller of spare parts for domestic cars. And believe me, this is not without reason.
Valve burning: Valve burnout rarely occurs due to poor fuel quality or if they are not adjusted for a long time. But first, it is worth checking the spark plugs and the four-output ignition coil.
Fluctuating RPM: There are numerous reasons for the unstable operation of this power unit, but most often faults in the sensors' operation or heavy contamination of the throttle body are to blame.
Critical breakdowns: If there is a dull metallic sound during acceleration and it intensifies with an increase in speed, then it could be due to knocking rod or main crankshaft bearings.
