In the era of fuel vehicles, the engine and gearbox of a car determine the lower limit of a car, in other words, if the power system of a car is not bad, then the car can at least be purchased with confidence, if not hot. Among them, the engine as the heart of a car, the importance of self-evident, in recent years with the continuous progress of engine technology and process manufacturing, has rarely seen a large area of engine failure, but buy second-hand cars can still not be taken lightly, today we will talk about a few problematic engines, we have to polish our eyes when buying a car.
The first, the GM 1.6L self-priming engine, codenamed LDE
Before 2015, GM was equipped with this engine in a number of its compact cars, it adopted the latest Ecotec DVVT and multi-point EFI technology of GM at that time, the maximum power was 86kW, the maximum torque was 150N·m, from the parameter point of view, it was indeed stronger than the same displacement engine in the same period, but in the GM car, the parameters often have nothing to do with the power, weak power, high fuel consumption is the general view of consumers.
In addition, this engine and GM's first and second generation 6AT gearbox, the same common diseases are very many, such as water pump leakage, oil seal leakage, high temperature and other problems are not uncommon, and this engine more than 5 years later, the probability of ignition coil damage is very large, P0016 fault code let the repairman see to scratch his head.
Vehicle type: Chevrolet Cruze, Buick Yinglang
The second model, the Volkswagen EA888 engine
Volkswagen's EA888 engine believes that everyone is not unfamiliar, from the listing has developed to the third generation, its advantages are very many, such as the use of compound injection and variable valve timing and other technologies, so that this engine whether in the power performance, or fuel consumption, have a good level, this generation of EA888 engine also redesigned the piston ring, and the oil and gas separator has been optimized and modified, so that the situation of burning oil has improved, the listing has been rarely burned oil feedback.
However, the problem of burning oil in the first and second generation EA888 engines is very prominent, whether it is a 1.8T or 2.0T engine has such problems, and the probability of occurrence is very high, the timing chain of these two engines is also easy to be elongated, which will cause the chain to jump teeth, causing engine failure, in addition, failures such as water pumps and ignition coils are also common.
Installed models: Audi A4/A6, Volkswagen Passat/Magotan, and Skoda Speedpie
The third model, the Nissan 1.6L engine, codenamed HR16
Isn't it strange to see this? Japanese engines have always been reliable in quality and low fuel consumption, and Nissan's HR16 engine has been used for more than a decade to have a good reputation, why is it on the list?
In fact, around 2014, the second-generation HR16 engine carried on Nissan's low-end models has appeared many cases of burning oil, and even new cars thousands of kilometers away, the fault is caused by the piston ring material problem, although the manufacturer has not given a clear reply, the Internet can be searched everywhere in the case of Xuanyi burning oil.
Vehicles: Xuanyi, Qida, Liwei, etc
The fourth model, peugeot/Citroen 1.6T engine
This engine is the main model of Peugeot/Citroën, which is still in use today, on the one hand, Peugeot/Citroen is indeed shy, on the other hand, this engine can still be played after many years, it can be seen that it does have its own unique features.
This engine was initially known as PSA Group and BMW cooperation research and development, 8 years ago its maximum power was 123kW, the maximum torque reached 245N·m, and at 1400 rpm can reach the peak torque, the performance is very strong, but it is also accompanied by the problem of burning oil, the reason is that the valve oil seal material durability is poor, its carbon deposition problem, high-pressure oil pump problem, water leakage and valve room cover oil leakage also have a lot of feedback.
The main problems of this engine erupted around 13/14, and the engine was also improved in the later period of Peugeot/Citroen, and the quality is still relatively stable.
Models: DS5/DS6, Peugeot 408, etc
The fifth model, SAIC 1.8T/1.8L engine
Many people may not be very familiar with this engine, if I said that roewe 550 used this engine, will you be more familiar with it?
The design of this engine is extremely unreasonable, such as its cylinder head screws are too long, the intake manifold is equipped with a waterway and the use of wet cylinder liners and other designs are controversial, it is easy to cause timing chain elongation, easy to jump teeth, burning oil, easy to high temperature cylinder pads and other common diseases, the most serious is that its antifreeze is always inexplicably less, and this engine repair standard is high, the rework rate is very high, so that the repairers have "repair the aircraft under the repair table, only Roewe can not repair" ridicule.
These two engines are not only used by roewe 550, but also used before models such as Zotye and MG.
Vehicles: Roewe 350, Roewe 550, Roewe 750, Zotye T600, Santa Fe, MG 3 and MG 5
The above several engines are equipped with many models, perhaps not every one will have problems, but it is still recommended to pay more attention when buying a car, buying a second-hand car itself is to save money, if you buy it for a long time, you need to overhaul the engine, it is simply not worth the loss.
What do you want to say about these gearboxes? What else is there to add? Feel free to leave a message in the comments section to discuss!
