Come on, Changchun Brother Audi A6L.0T, also known as C6, the sixth generation of C-class cars, belongs to the top generation of the world, and is also the pinnacle of the Audi A6 series. The overall condition is okay. Let's do some preparations today to let him return to the peak [like]
Although the overall condition is OK, it is just the whole, it is a rough... In terms of details, the word classic has been defiled many times. Just for this kind of counterfeit screw, what is the classic look?
and this bumper bracket go where did you go? "Where Are Dad Going?" wasn't popular in the past few years? Did Dad break this bracket off by Dad?
A bumper with three different counterfeit screws [covering your face] can also be regarded as a counterfeit style and level, so classic old cars must pay attention to details.
Explore it in and find more dark pits. Why is the back cover of the headlight missing? This car is either missing this one or missing that one... Alas, there is no way, after all, it is impossible to have no problems for so many years.
Since it is a refurbishment of the whole vehicle, we will start with oil and water. According to the information provided by the owner, this car has not changed the brake oil for five years. Since that is the case, let’s start by replacing the brake oil.
details! The essence of old car renovation lies in the details! have a look! Where did the screw cap on the wiper go? Without this thing, it is not only not beautiful, but also prone to rust.
The era of changing brake oil with your feet on the pedal is over, and the era of changing brake oil with a fully automatic machine has arrived. This way, the era of changing brake oil is completely and clean.
The old oil in the brake system needs to be replaced cleanly. Each brake pump must be put one by one, and put it thoroughly one by one...
Just look at the green-haired brake oil released. You can imagine how long it has been since I changed [cover your face]
Each wheel must be put all over, and you must put it thoroughly. You must never do anything to cut corners.
Then pour the replaced brake oil into the waste oil barrel... The black and green brake oil is really shocking to look at.
After changing the brake oil, continue to replace the brake disc and brake pads... The state of the brake disc being worn is no longer possible to repair it, so just replace it with a new one.
This is the imported brake disc used when this Audi was first introduced to China. Later, the brake disc was not seen in China when it was produced in China. But fortunately, I have another set of them in my family, which allows my brother to use the imported original brake disc, which is worthy of the classic old cars.
Germans like to wrap parts with tarpaulin, which seems to be their habit. There is also anti-rust oil on this brake disc that has not dried up. The original manufacturer after domestic production has been changed to spray paint to prevent rust. Everyone can express their opinions on which of the two methods is better. I really can't find the German version of the brake disc, I can only use domestic ones. In fact, domestic products do not mean bad. After all, most of Audi's accessories were domestically produced in the later period. After opening
found that it actually had the word "Germany" and the workmanship and quality are also good. No matter what, the things are good anyway, who does it produce it? [cover your face]
Remove the old brake disc and brake pads...
replace with a new disc and a new disc, which looks quite good...
Next is the key task, digging coal and removing carbon... This machine is not going to overhaul this time, because burning engine oil is not very good, so we plan to remove carbon deposits for him and make a disassembly and control burning engine oil.
There are many parts that need to be removed from carbon, such as combustion chamber , air intake valve... There are also many ways to remove carbon, such as walnut sand, dry ice ... But the one that can pull the pus is a good plaster, and the one that can be handled is a good method.
Look at the location of the intake valve, which is full of thick carbon accumulation. The car owner cleaned it up in Changchun not long ago. Now there are carbon accumulations again. Carbon accumulations at different locations have different harms. For example, if the carbon accumulation in the intake valve falls into the cylinder, it is easy to cause the cylinder to be pulled. Even if it is not dropped, it will affect the intake efficiency.
This carbon deposit cleaning brush is very popular on the Internet recently. It is said that it has been cleaned very clean. I specially bought one and try it...
imitates the way it looks online while spraying cleaner while brushing the valve... The 2.0T direct injection engine seems to never escape the curse of carbon deposit, so you must clean the carbon deposit regularly.
To be honest, the washing effect is not satisfactory. If you are a little careless, you can hand over the car [grin], but I insist on the principle of removing carbon, so I still cannot accept this effect.
Forget it, please come out to clean our walnut sand. Sometimes the equipment is really better.
This way, the effect after washing is worthy of the audience. To clean the carbon deposits, you must see the true color of the metal to be considered as passing.
We repair the car and will never leave any hidden dangers. We have removed the air intake manifold , so the old fuel injector seal ring must be replaced at one time, and the qualified old seal ring itself has also aged, cracked and damaged.
Germany imported and equipped with Aierling's fuel injector seal ring. The original car was equipped with his, so using this seal ring is a bit expensive, but it is safe.
Install the intake manifold, and remove the valve chamber cover and prepare to change the seal because of oil leakage...
Looking at the color inside the engine, I can say responsibly that the maintenance of the engine oil was definitely not the full-synthetic oil . In today's era when the full-synthetic concept is a big street and the synthesis concept is mixed with fish, there are not many repair shops that can really use good engine oil for you.
Replace the valve chamber cover pad and prepare to cover the cover back. The problem of oil leakage will be solved.
The problem with refurbishing of old cars is that some accessories are really hard to buy. Just like this car, the bottom bracket underneath is broken and it is not possible to buy it. What should I do? Just repair it! I'll find a master to weld you back.
is this bracket. Weld a nut so that the base plate screws can be installed... The previous nut and bracket were desoldered due to impact and could only repair it by themselves.
Put this repaired bracket back onto the water tank frame, and a detailed problem has been solved...
Because this 2.0T direct injection engine is the first direct injection engine in history, the transmission system still uses a belt, and the maintenance manual stipulates that the belt will be replaced every 80,000 kilometers. Here we ordered a set of original belts to be replaced.
, it’s all original parts and timing belts. This Audi has two supporting manufacturers, one is Ina and the other is Continental . Friends who want to save some money can buy these two brands, but as a patient with obsessive-compulsive disorder, I will decisively use the original label and code.
This car does not require dismantling the front frame. It has a large position and is designed with a humanized design. Basically, a skilled master can handle it in half an hour.
new belt is in place. Although the maintenance manual says to replace 80,000 kilometers, I personally think there is no problem in driving 100,000 kilometers.
Next, continue to worry about the details. This car has been ripped off for a while before, and many small screws and lids are gone. Don’t look at the small things, you are afraid that small things will be difficult to find when repairing the car. The screws for this ignition cable sheath are hard to find.
Even if it is a screw, I will find the original one for you. This is my usual style and principle of my brother. It costs dozens of dollars a small screw. Do you think I am crazy with my brother?
original screws are in place, and the strong German flavor is back. This is what the classic German old car in our minds should look like.
Then prepare for today's highlight, cleaning the carbon deposits in the tank. To put it bluntly, carbon deposits in the combustion chamber are cleaned. The carbon deposits in the combustion chamber directly affect the engine oil burning, especially the machines that directly inject into the cylinder. The carbon deposits in the cylinder must be regularly removed. First remove the spark plug , but the spark plug is also shattered enough, so I will change it later.
Through endoscope we can see a thick layer of carbon in the cylinder. If this thing is not handled cleanly, it can easily cause the cylinder to burn the engine oil, and it will be completely troubled. There are many ways to clean the carbon deposits in the cylinder, such as filling cylinder cleaning, dry ice cleaning... But today we use a new and gentlest way to clean it.
We pour fuel treasure raw liquid into engine oil barrel , and mix it with a variety of potions to make homemade fuel additive . Use this potion to replace gasoline, clean it and run it for carbon deposits. It not only cleans the carbon deposit in the combustion chamber, but also releases piston ring that is stuck by carbon deposits.
Of course, you also need to redeem a certain proportion of gasoline...
Add a little bit of engine oil as cylinder moisturizing agent, you can only add a little bit...
Since you have washed, then wash the oil and oil channels together. I saw that the engine was darker in color and there was a lot of oil sludge. We washed oil sludge together while cleaning the carbon deposits.
Come on, pour in a can of sludge cleaning agent, and the engine will run for two or three hours later. Just use this time to wash the engine's stomach.
Pour the cleaning potion into the drip bottle... Use the potion as fuel, clean and run while cleaning, without wasting the owner's gasoline, and then do the work again. Beautiful!
OK, hang up the dandruff bottle and start cleaning. It’s a long three-hour cleaning process, don’t worry.
In these three hours, we have a lot of things to do, such as the real headlight back cover that can be installed for it while it is broken.
This broken bracket, install it back in this fragment time...
Various counterfeit screws replaced him with the original screws at this time...
Someone said that cleaning carbon deposits is an IQ tax... Let's talk about everything, water begins to come out of the exhaust pipe...
I saw it clearly, it is really water coming out. What does this mean? It means that the combustion is good... After the carbon deposit is cleaned up, the gasoline is burned well, which not only reduces fuel consumption but also increases power.
exhaust pipe is constantly detoxifying and nourishing the skin. Don’t worry, after such a thorough cleaning, there are many benefits to the car. Engine cleaning is actually an important part of the vehicle maintenance.
In addition, we also plan to change it to a new set of spark plugs. This EA113 direct injection engine and EA888 spark plugs are universal and can be used with confidence.
This is the situation in the cylinder after washing. The carbon deposits are basically dissolved and burned, and you can see the true color of the metal. But don't expect that white color, it's something that someone else has done to show you.
We strive to show you the most realistic effect. This kind of slight black but basically clean and yellow is the most realistic state after cleaning. My buddy is real, so there is no need to cheat.
Replace four original spark plugs... Volkswagen original is actually Audi original [covering face]
Next is the topic of preventing carbon deposits. Burning engine oil has a close relationship with carbon deposits. We have cleaned the carbon deposits before. If we don’t do prevention, wouldn’t it be a waste of washing?
Give the car a can of fuel additives... This thing is actually what everyone often calls fuel treasure... To be precise, fuel treasure is one of the fuel additives. It is recommended to use fuel additives regularly by direct injection engines in the cylinder.
The engine oil released after carbon deposits and sludge cleaning in the cylinder will be particularly black. It is not a gimmick, but really black...
Because this car is slightly burning the engine oil in the future, we plan to add a bottle of piston ring release agent and carbon deposit sludge inhibitor before adding the engine oil to further dissolve the carbon deposit on the piston ring.
Pour a bottle of blue color...
Pour a bottle of golden yellow...
Use full synthetic engine oil, and car maintenance requires full synthetic engine oil, especially high-end models, which really get what you pay for.
Since it is the preparation of an old car, how can you forget the gearbox after getting the engine? This transmission oil is so black, and it is estimated that it has not been replaced for more than 100,000 kilometers.
Pour the transmission oil into the container...
Use a special connector to import the oil into the inverted transmission...
Car maintenance is not as simple as changing the oil. Look at this filter element, it has grown hair. Do you change it or not? [cover your face]
Look at this gasoline filter element. I guess I have never changed it after buying a new car, and it has accumulated more than ten years of scum inside. After pouring out
, it was shocking. Brothers, the gasoline filter must be replaced regularly.
Change the number of new gasoline filter element. At least for some time in the future, the problem of gasoline filtration will definitely be clean.
Since it is an old car, there must be some hidden diseases. For example, although this car does not have a fault light to alarm, its power and fuel consumption are always unsatisfactory. Why? You can find that there is a suspicion of air leakage when looking at the data flow.
Using the smoke leak detector, you can clearly find that there is a crack in the lower tube and air leakage...
Remove this tube and find the location of the crack. It is this small crack, which causes the entire engine to be in poor working conditions.
exhaust pipes were originally unreliable and could not buy them at all. I dug three feet to find them... I found a relatively reliable brand product. Anyway, it was just a piece of pipe, just not leaking.
Aging and cracking are all greasy turbocharger tubes, and they are replaced with new ones...
Check the data flow again. This is the standard data flow. The problem of air leakage is successfully solved...
When this car came, the owner explained that the exhaust gas has never passed last year. The reason is that the three-way catalyst is not good. Moreover, it seems that the owner has changed a three-way catalyst before, but it is definitely a miscellaneous brand of the sub-factory.
Let’s change it to a Huake, which is made by the original supporting factory. Although it is made by the same factory, it is estimated that the supply to Audi OEMs may be better, but since it can provide the market and is from the original OEMs, it is probably not too bad.
What is this "big hole"? That's right, it's the fuel tank, why is there a hole? Because we removed the oil pump [Tears]
The duty cycle of the original car's oil pump reached more than 90%, which means that the efficiency is inefficient. In order to increase the power, we plan to replace it with a new oil pump.
Hehe, the new oil pump is in place, and the missing power has been made up...
Next is to replace the power steering oil. Have you used this method of changing power steering oil in cyclic power steering oil? From the return pipe , force the old oil out...
Then add new oil from the engine oil port and cycle continuously until the oil color comes out of the return oil port is the same as the new oil.
At the beginning, the old car is inseparable from spray painting. In fact, the whole car paint is OK, but this bumper is a bit sorry to the audience.
It doesn’t matter, change to a new bumper and repaint it, it’s beautiful!
In addition, the areas that cannot be seen cannot be ignored. For example, the engine's lower guard plate is full of holes and is tied with iron wire in many places.
The screws and snaps are also damaged and missing... How can something like
be worthy of the refurbished style of our classic old car?
decisively order a new engine lower guard...
equipped with screws and snaps...
installs new engine lower guard...
installs new transmission lower guard...
found a "bang bang" slap at the rear of the car last night. It turned out that the fixed bracket of the rear bumper spoiler was scraped.
decisively order and replace the fixed bracket...
After the spoiler screws were fully equipped, the abnormal noise problem was solved.
broken dipstick...
Replace a new dipstick...
So the details are renovated in place, and going out for a test drive is so cool. The power brought by the direct injection engine and the solid workmanship and material experience of the old car are not replaced by a new car.
After several days of test drive, it was confirmed that the whole car had been perfectly repaired. The old car returned to its peak, and it was time for this old car to say goodbye to our column team. With a reluctant mood, we bid farewell to this old car. From then on, there will be another classic Audi A6 that is rushing to lightning in the black soil of the Northeast.
