How much does engine 126 and 127 cost?
Engine 126 has catalog number 21126100026030, sells for about 107,000 rubles, engine 127, respectively, has catalog number 21127100026030, its price is slightly higher by 3-5 thousand rubles. The price on the secondary market will be significantly lower (up to 20-25 thousand rubles), but the savings will not pay off - a used “engine” can last no more than 1000 km, this is a real lottery.
How to find out what engine is in a Priora
You can find out by looking at the plate on the left glass of the rack, where the engine number is written on the edge. From it you can understand the 8-valve unit, or 16. You can also recognize the modification 21126 or 21127.
Oil
The oil used in this engine is similar to 21126: synthetic, semi-synthetic
5W-30 5W-40 10W-40 15W40
Oil sump volume
This point will be useful for those who are going to change the engine oil. With different transmissions, the volume of oil poured into the engine is also different.
VAZ 21129 + Renault manual transmission (cast crankcase) = 4.4l
VAZ 21129 + robot (stamped crater) = 3.2 l
The engine resource is 200 km. But in practice, you need to monitor the condition of the roller, pump and timing belt, because if individual valve elements jam, they will meet the piston group, and then both will come to an end. In addition, during the impact of these elements, it is not uncommon that the crankshaft bends slightly. You can drive with such a crankshaft, but there will be huge oil consumption.
Owner reviews
The plant positions the new VAZ-21129 power unit as a modern engine with good dynamic performance. The new engine is in many ways similar to 21127, which bothered car owners with the appearance of noise, knocking and tripping. The near future will show what the power unit will turn out to be in practice. Leave reviews and recommendations for operating the VAZ-21129 engine in the comments. Also evaluate his work in the survey at the end of the article.
Let us remind you that on the dynamometer stand this power unit showed 7 hp. more than indicated in the passport.
Features of 21129 engine/differences
The main feature of the 129 engine is the “innovative” for AvtoVAZ installation of an intake receiver with variable chamber geometry and volume. Due to the damper, the volume of the intake chamber changes depending on the speed. As practice shows, the damper is activated at 3500 engine speeds.
In addition, the engineers managed to get rid of the mass air flow sensor - mass air flow sensor. Along with him, his ailments went away, which tormented the owner of the 21126 engine: unstable idling, sometimes exorbitant consumption, high cost. Instead of mass air flow sensors, engineers installed a connection from DBP and DTV sensors (atmospheric pressure and air temperature sensors). This is where the differences from the 126 engine end. Speaking in fact, the intake system with variable geometry is as old as the world and has been installed by global manufacturers almost since the 80s.

The structure and design of the VAZ engine, no matter what the standard, is typical for most modern mass-produced engines that are intended for budget car models (
the table with characteristics is located below in the article
).
The key feature of the power plant under consideration is the internal combustion engine’s compliance with Euro-5
.
AvtoVAZ
to apply the Euro-5 emissions class through a major modernization of its 16-valve 1.6-liter engine series
21127
, which was taken by the manufacturer as an experimental basis.
The company's engineers first made changes to the intake system, slightly clamped the exhaust and loaded updated firmware into the “ brains
”.
In addition, the power plant received new supports and an oil pan, as a result of which it was moved to a rigid subframe.
The modern internal combustion engine of the 21129
is fully adapted for the installation of an alternative transmission of the French brand
JR5
.
As for the key components of the engine in question, everything is according to the classical scheme: a cast-iron head with a cylinder block ( 4 cylinders, in-line arrangement
) with a lightweight connecting rod and piston group manufactured by
Federal Mogul
for 16 valves.
The basis of the fuel system is the injector. The gas distribution mechanism is equipped with a belt drive
with an automatic tensioner, and hydraulic compensators are installed in the head of the unit. As for the intake system, it is regulated by special throttle valves.

Frequent overheating in summer and prolonged warming up in winter
.
Many car owners, new and used Lad Vesta
,
X-Ray
(
X-Ray Cross
),
Largus
, are extremely dissatisfied with the quality of thermostats that are installed at the
AvtoVAZ
and, as a rule, it is these internal combustion engine elements that cause a storm of indignation among the owners of these cars.
It is precisely because of an unfinished thermostat that in hot summer weather there is a fairly high probability of the power plant boiling, and in the literal sense of the word. As for the winter period, everything is the other way around; the engine simply takes a long time to warm up. 2
.
Premature failure of timing components and timing belt breakage
.
According to the manufacturer's regulations, maintenance of the gas distribution mechanism must be carried out once every 180 thousand kilometers. Moreover, according to auto mechanics, the timing belt
actually works out this mileage, but the idler pulley and water pump of the system tend to jam at 140-160 thousand kilometers.
The most unpleasant thing for car owners in this matter is that if the timing mechanism slips, then the drive belt automatically breaks, and after it the pistons bend the valves and “ hello
” overhaul.
For reference, we note that, according to the manufacturer, engines produced after July 2022 are not subject to valve bending when the timing belt breaks ( we cannot but confirm or refute this fact, sorry
).

.
Engine tremors at idle speed
.
A certain proportion of car owners claim that on the internal combustion engine in question there are frequent cases of tripping at idle, and this problem is often caused by faulty spark plugs and/or ignition coils. In some cases, tripling may occur due to excessive contamination of fuel injectors, which can be easily washed with special auto chemicals. 4
.
Extraneous knocking noises in the engine compartment at idle
.
According to many car owners, quite often strong knocking sounds similar to the clatter of hooves are heard from under the hood at idle. According to experts, this sound comes from hydraulic compensators, and many owners of different Lad models have already managed to change these engine elements under warranty. 5
.
Minor ailments and problems
. The main, but very unpleasant problem of the engine under review is the crankcase ventilation valve, which often jams in cold weather, even mild ones. Such a nuisance contributes to the fact that excess pressure of the engine oil simply squeezes out one of the seals, as a result of which lubricant leaks can no longer be avoided.

Today, the engine under review is still considered relatively new, so finding a similar internal combustion engine on the market with even minimal mileage is quite difficult. Sometimes on popular sites you can find single copies with low mileage, but the history of such power plants is quite dubious, and no one gives any guarantees when the price of a contract internal combustion engine is 45-50 thousand Russian rubles. As for the new unit, official dealers are ready to sell you this motor at a price of 120 to 140 thousand Russian rubles.

In conclusion, we note that the service life of the VAZ 21129 series 1.6-liter power unit, according to the manufacturer, AvtoVAZ, averages 200-230 thousand kilometers before overhaul or replacement.
However, often in reality, the lifespan of a VAZ engine can reach 250-300 thousand kilometers before serious breakdowns ( for reference: from the words of “hardened” taxi drivers
).
