The gasoline carburetor 1.1-liter VAZ 21081 engine was produced specifically for export versions of Lada cars.

A little about the design of the engine Lada 21081 8 valves

Especially for export to countries where there were tax incentives for small-capacity units, a motor with a displacement of 1.1 liters was developed. This was done by installing a different crankshaft with a smaller piston stroke. The cylinder block was made a little lower, by about 5.6 mm. There are no other differences.

The VAZ 21081 engine number is located at the junction of the block with the head

Otherwise, this is a typical eighth-family internal combustion engine with an overhead single camshaft, timing belt drive, and without hydraulic lifters. So locksmiths will have to manually adjust the thermal valve clearances. And also when the valve belt breaks, it bends in almost one hundred percent of cases.

Reviews, oil change regulations and resource 21081

As a result of re-export, a certain number of Lada models equipped with such a power unit returned to us. And although their owners are usually not very satisfied with the power characteristics of the internal combustion engine and its low reliability, inexpensive maintenance and penny spare parts easily cover the disadvantages.

Experienced servicemen recommend that drivers carry out oil service more often than the 10 km specified by the manufacturer. Better every 000 - 5 thousand km. The replacement is 7 liters of semi-synthetics 3W-5 or 30W-10. More on video.

The AvtoVAZ company declared an engine resource of 125 kilometers, but according to the experience of using it, it is about one and a half, or even two times more.

The most common engine failures 21081

Troenie

The failure of one of the components of the ignition system is often accompanied by tripling of the power unit. First you should pay attention to the cover of the distributor, high-voltage wires and candles.

Float turns

Almost all problems with the unstable operation of the power unit are somehow connected with the Solex carburetor. You need to either learn how to clean and repair it yourself or make friends with a good specialist whose services you will need constantly.

Other breakdowns

We will talk about all the remaining breakdowns briefly. The engine is prone to detonation and does not like bad fuel very much. You have to constantly adjust the thermal clearances of the valves, otherwise they will knock loudly. Often there are oil leaks in the valve cover area. The motor often overheats due to a malfunction of its thermostat.
