Volvo is not necessarily the most luxurious car in the world, but it may be the safest car in the world.
Volvo has always been known for its superior security, and the bosses who bought Volvo also went for this. After all, a rich life needs safety to ensure it. If you don’t have safety, no matter how rich you have, it will be useless; Because 70% of new wives, 80% of new houses and huge wealth that have not yet been heated must be based on living well. There must be no accident in the car. If something happens, it will be a big deal. Once something happens, a child will be an accident, and your wife, the house and Wealth is all about others, so the safety of buying a car is the first priority.
In the face of burning engine oil, everyone is equal. Even if it is the safest car in the world, no one stipulates that he cannot burn engine oil ? How can a car be advanced without burning oil?
0 There is no limit on the model, no borders, no distinction between high and low, so you must recognize it if you burn it, and you don’t have to beat your chest and stamp your feet and be upset. Just repair it.
This is the vehicle nameplate, that is, the vehicle ID card. The car in 2011 seemed that Volvo did not belong to Geely at that time, just like Land Rover does not belong to that person, it is the same truth.
two fault codes, don’t worry, this is a common problem with this engine, the chain wheels are broken. It seems that the chain wheels have become consumable parts on , Mercedes-Benz, and Volvo, and they must be broken regularly. Although Audi also burns engine oil, Audi's chain wheels are not easy to break. I would like to praise Audi here.
real-meter kilometers are more than 270,000 kilometers, and it is normal to burn some engine oil. However, it seems that some cars of this machine also started burning when they were tens of thousands.
Pull out the dipstick and look at it. It seems that there is no oil in it. It seems that there are two liters missing...
Looking at this cabin, do you think it looks very familiar? Yes, it is used with Ford, Land Rover and other models The 2.0T engine is very classic, and it is the top ten engines of the world of in the past . It seems that it has entered the top ten in the world at the same time as Volkswagen's EA888 (it's true that they all burn engine oil) [grin]
without any delay, cleanly open and remove it, hurry up and solve the problem. Be sure to hand it over to the car owner before Mid-Autumn , and they are waiting to use it.
Designed in this car, you must first remove Yuanbao beam . This subframe is thick enough, and the steel plate is so thick that it is worthy of being the safest car.
Two young men lifted the ingot beam to one side first and put it on...
The next one is the engine. Not to mention how the machine is designed, just looking at the aluminum alloy oil pan, you can tell how conscientious the materials are. Alas, BMW and Audi's plastic oil pan, you can have some fun.
Removed the dirty engine oil, and there was not much release. It was indeed the engine oil burning, and it was almost burned.
cut off the engine wiring harness and pipelines... During this process, I found that many pipelines and engine bracket owners on the outer side of the car had changed. As expected, they were the owners who were not short of money, so they went to buy Volvo.
Lift slowly lifts the body, and the engine and gearbox fall down.
The guys started to disassemble the machine with a smile. As for work, you should do it happily, and don’t be emotional.
Remove the chain cover...
Remove the exhaust valve . The exhaust valve of this car is very simple. It is a single vacuum valve with several coagulation plates to separate oil and gas in the most primitive way. But the more primitive the method, the better the effect.
rotates the chain wheel by hand, and the amount is very wide. The intake chain wheel is 100% wasted, and the exhaust is also empty, which is not as large as the intake air, but it is already very large.
Remove the cylinder head... This machine is indeed conscientious, cylinder head and cylinder block are both aluminum alloy.
starts to decompose the cylinder and remove oil pan , which is oil pump and balance axis .
Remove the large tile...
Where did this metal fragment come from?
Take out piston one by one...
has the culprit for burning the engine oil found? piston ring 's gas ring is about to match, and the oil ring is blocked by carbon deposits, which is the biggest reason for burning engine oil. To solve this problem, the piston ring must be improved.
Piston has the piston on the back of the foundry manufacturer KS and the piston size is 87.43 because the cylinder diameter is 87.5. There is a slight strain on the cylinder wall of
. It is estimated that boring cylinder is needed. However, this car is not very good at boring cylinders. Its special structure determines that it is not easy to boring cylinders. This is a later story.
But this kind of strain must not be ignored. If this problem is not solved, the problem of burning the engine oil cannot be solved.
Please click on the table are the three key points of this repair. The repair of the cylinder, the replacement of the valve oil seal , the improvement of the piston ring...
As soon as you look at the top of the piston, you will know that the owner must not have the habit of using the fuel additive , because this car uses a direct injection engine, if not Fuel additives, carbon deposits will occupy this place, which will lead to burning engine oil over time.
The master of boring the cylinder took the things away... But he said that this car cannot boring the cylinder, so he could only clean it for me. As for how to repair the strained cylinder, let me find a way for myself...Brother... You are going to do it. It's my death.
Camshaft also had obvious strain... and it was in the first shaft journal. I wanted to let it go but I was afraid of engine oil pressure relief...
looked carefully and the strain was very deep. I gritted my teeth and changed it... …
All four cylinders have been polished, and some marks that are not really strained are gone after polishing, but this slender stretch mark has always existed. What should I do? Can't bore the cylinder... Then...
Fortunately, Yongkang is the capital of hardware, the processing industry is relatively developed, there is a process called metal spraying... The thing is taken to spray and then polished to process cylinder , the scratches were repaired.
But here I want to mention that if it is a large-scale strain, the spraying process will be useless, so it is recommended that everyone use fuel additives to avoid large-scale carbon deposits falling off and causing large-scale strain.
After repairing, the guy will further clean the cylinder. All the pieces of metal processing must be cleaned...
OK, the engine is installed. Apply special assembly oil to each large tiles, which is more effective than applying engine oil. good.
Tighten the large tile screw according to the specified torque...
Since the problem lies in the piston ring, the piston ring needs to be improved. Using an improved piston ring, this wave ring is not easily blocked by carbon deposits and can be more durable.
But when installing the piston, I found that there is no suitable tool, what should I do? Find our lathe prince Fat brother here!
This separately processed 87.5 piston funnel has been finely ground at the bottom and will definitely be extremely smooth to use, hehe.
It feels really comfortable, silky lubricating, and you can slimly enter with a slight poke. One word, it’s great!
Tighten each small tile screw according to the specified torque...
Balance shaft mark facing the oil pan...
crankshaft upper dead center fixing tool inserts into the cylinder to ensure that crankshaft is in the correct position...
Install the oil pump chain wheel...
00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 Install the crankshaft oil seal...
Install the most conscientious aluminum alloy oil pan. Alas, in today's cars, you dare to use plastics. It is said that some people dare to use plastic hem arm...
Install the flywheel disc...
The engine and the gearbox are perfectly connected...
The strange thing about this car is that such a high-end car does not use hydraulic heading columns, but uses mechanical heading cups. Is it to save costs? As long as you use the mechanical top cup, you must check and adjust the valve clearance.
Because the camshaft was replaced, the gap between the two top cups was wrong. I changed two top cups here. If the gap between the valve is wrong, not only will the engine sound bad, but it will also affect power and fuel consumption.
lift the cylinder head...
tighten the cylinder head screw according to the prescribed torque...
replace the new exhaust valve...
install the turbocharger...
install the injector ...
replace the two brand new The chain wheels are directly used for the Ford service station. The price of the same machine Volvo is 1.5 times that of Ford...
Update all chains, tracks and wheels, and tighten the screws of the chain wheel according to the specified torque.
Install the chain cover...
After replacing the front oil seal of the crankshaft, use special tools to fix the crankshaft belt tray. This has a position.
, timing mark must be aligned... Otherwise, a fault code will be reported at that time.
Use the original matching spark plug , NGK double platinum spark plug...
spark plug ceramic part to avoid sticking to ignition coil rubber ring in the future.
Replace the new spark plug...
After updating all seals, install the valve chamber cover. At least in the next five years, it is estimated that this cover will not need to be removed again (in five years, sealing gasket may age).
Repair the car and halfway it, and came to this cute fat man's place to process things, which is to process this gasket ...
Because there should have been gaskets in this place, it was thrown away by the previous repairman, and I bought it as well as I bought it. If not, I can only process one by myself. The gaskets processed by
come in handy, and the entire installation work can continue...
installed the entire set of belts, and the installation work is basically done...
engine assembly has been completed. In fact, compared with EA888, the structure of this machine is simpler.
The only troublesome thing is that the engine enters the cabin is in the way, and it is not as comfortable as the EA888 can sink.
organizes the wiring harness, and the engine can enter the cabin...
slowly lowers the body, and the engine enters the cabin...
Fix the screws at both ends of the engine and transmission , and they will not fall off.
connect the wiring harness and pipelines...
heavy Yuanbao beam subframe needs to be pushed back...
continue to connect the pipelines and lines...
add full synthetic engine oil , the real full synthetic engine oil is not 88 and the 99's kind.
Fill power steering oil...green, not red transmission oil .
successfully started the vehicle, and a stream of blue smoke came out of the exhaust pipe, it was cool!
Next, a gratifying scene appeared. The water vapor in the exhaust pipe became more and more, and the entire lens was covered with a layer of water vapor. This means that combustion is good. The car that burns the engine oil will not have water vapor.
Black water is sprayed out from the ground, detoxifying and nourishing the skin [grin], it's great, these will definitely not burn engine oil, and they can also be very fuel-efficient.
Because the subframe has been moved, four-wheel positioning must be done. Finding Master Aliang to position it is our compulsory course now.
All data must be adjusted to the best state so that you can have a good driving feeling.
Because this car is a direct injection engine, in order to avoid carbon deposits, you must use fuel additives to prevent carbon deposits from starting with a new car.
Carbon deposits are the cancer cells of the engine. They should be eliminated as much as possible in the bud, and then they will suffer endlessly. It is recommended to add a bottle of fuel additives to a box of oil, which is the most economical and guarantees the effect.
went out for a test drive. Generally, we will test drive dozens of kilometers to one hundred kilometers after overhaul...
all speed ranges have to be tried, because fuel additives are added, so we fill it with the oil...
Along the way, the fun this engine brings us has emerged one after another. To be honest, compared to the EA888 engine, this machine has more powerful power and more direct output. Of course, there are unique advantages between the two and no match.
Mid-Autumn Festival is approaching, and we try to hand over the car to the owner as soon as possible, because holidays are the peak period for car use, and today the wind is sunny... It should be the intersection of wind and clouds, and it is also a zodiac auspicious day for delivery. We retrieved the car from Xinchang , and drove it back for him today [grin].
So the question is, will this Volvo not burn engine oil in the future?
of course! Otherwise I would have a hammer [covered my face]. However, if the car is repaired, the owner must cooperate with maintenance and use.
1. Change the engine oil on time for maintenance. It is not required to have 5,000 kilometers, but it does not exceed 10,000. It is recommended to change the engine oil within 7,000 or 8,000 kilometers.
2. Use fully synthetic engine oil that meets the specifications. The oil cover of this car says 5W30. Combined with the fact that this car is a European and American engine, you must use the high viscosity engine oil inside the 5W30, such as A3B4 level or C3 For grades, you must not use A1B1, which is used in Japanese and Korean cars.
3. If the filter element is dirty, replace it. Don’t blow it and continue to use it. This will lose the filter effect, which is equivalent to in vain.
4. Use fuel additives regularly and strictly control the amount of carbon deposits. If the amount of carbon deposits falls off due to excessive carbon deposits, we will not provide quality assurance because this is a problem caused by your not caring for the car, not a quality problem.
Finally, everyone is welcome to add to the shortcomings of my writing in the comment section. If there is any mistake, you are welcome to criticize and correct me. I wish you a happy Mid-Autumn Festival. #Share your experience today# #Check-in Challenge Bureau# #Mid-Autumn Festival talks about homely #
