What’s new?
The easiest way to recognize the modified engine is by the cylinder head cover – it is attached with six screws for the “reverse Torx” E8, and not with two cap nuts, memorable from the VAZ-2108.
In total, almost fifty details have been changed. Another is now the cylinder head with a gasket. Some parts are united with other VAZ engines – 1800 cc domestic and “alliance” H4M.
The new units are generally less material intensive – a crankshaft with only four counterweights and narrowed crankpins, a hollow camshaft with narrow cams, the head itself, valves with thinner stems, more compact valve seats.
All this makes the engine cheaper to manufacture.
What is good and what is bad?
There remains a “plugless” piston design, where a broken timing belt does not lead to a major overhaul. And some good, proven solutions of the VAZ-11189 engine. For example, a semi-automatic timing belt tensioner, piston cooling nozzles or a one-way thermostat, through which the very small circle of the cooling system passes through the stove and quickly warms up the interior in winter.
The camshaft cams have been narrowed considerably, especially at the rear. The pushers are solid, coming from the H4M engine.
But many new solutions are controversial.
Spark plugs with a 12mm turnkey thread “on 14” roads are not available in every store. The established Brisk MR14-LC with a copper electrode cost 1000 rubles each in April, although in June they fell in price to 350-400 rubles. It is still expensive because this is the price per piece!
Candle factory prescribes to replace every 30 thousand km. And it is better not to touch them unnecessarily – the thin and fragile outer insulator is easily damaged.
The new valve cover gasket is silicone, which is great. Only the original costs 500-1000 rubles! The choice for non-original is still very poor.
It is comforting that up to 90 thousand km you can not climb under the hood – this is exactly the time until the first adjustment of the valves with one spring and a solid pusher. But the work will be long and expensive: to select pushers you need to completely remove the camshaft, and each pusher will cost about 500 rubles.
New cylinder head gasket – so far only the original for 2000 rubles (for the old VAZ-11189 you can take 300 rubles).
How happy?
Grant drives a VAZ-11182 more pleasant than before. It’s not so much the three horsepower gain that’s felt, but the 80 percent availability of torque as early as 1,000 rpm. Of course, 143 Nm of Lada does not make a cannon, but the elasticity of the engine is good – you can change gears less often.
There is less noise and vibration. And although the compression ratio has increased slightly (from 10.3 to 10.5), you can fill in the AI-92. Granted, with the caveat “if AI-95 is not available.” But for whom is it available in the current economic situation?
As promised, oil consumption for waste will be halved. The oil separator in the valve cover has been significantly enlarged for this purpose. Oil scraper rings – removable, from the improved engine 1.8. The declared resource of the engine is 200 thousand km. Admittedly, we have not yet noticed much economy: in the combined cycle, the editors Grant consumes 8.5 l/100 km.

Last year, Largus and Grants began installing a new base engine – a 90-horsepower eight-valve VAZ-11182. Do not look for logic in the numbering: it replaced the 87 hp VAZ-11189.
