Engine Overview and Common Failures
The weight of the VAZ 21179 engine according to the catalog is 110 kg. The engine number is located at the junction with the gearbox. Since the beginning of production and up to the present day, car owners with this engine complain about excessive oil consumption. There are many opinions about the causes, but it seems that we are dealing with design features, as the lubrication consumption disappears after honing and adjusting the piston clearance to normal. Another common problem with the engine is the sticking of the oil pump relief valve in the open position due to the accumulation of combustion products and other dirt particles. The drop in lubrication pressure leads to rapid wear of the crankshaft and camshafts. On a specialized forum, there are complaints about regular oil leaks from the camshaft plugs and wear of the fuel supply pipe against the wiring bracket, and even cases of fires. It is also important to monitor the condition of the timing belt, as its breakage can cause valve damage.
