"Engine cylinder heads, valve chamber covers, camshaft position sensors, oil leakage is generally caused by oil seals and gaskets."

"This car is the crown of '07, it runs a lot, and the owner doesn't maintain it much, you can see that your 10-year-old Xiali is about the same as this.

If the car has severe oil leakage and thick oil sludge, it means that the oil leakage time is very long, and the owner has not dealt with it in time, and the car condition can be imagined. ”

Speaking of this, Lao Wei also squatted down and pointed to Li Liang to point out the oil stains that leaked onto the chassis.

When Li Liang thought of his extension, the oil sludge had already covered the steel mark under the engine, and he nodded unconsciously.

"Of course, this situation generally does not cause much problem, sometimes the oil sludge is thick, but also because the owner spilled when adding engine oil."

Lao Wei smiled in a low voice: "What I taught you today is another point, can you remember it, if you look away?" Hey, he......y, hey, hey

Hiss!

Li Liang gasped and took a breath of the special cool air provided by the auto repair shop wrapped in the smell of engine oil, and Lao Wei, who looked at the strange smile, couldn't help but complain in his heart: It is estimated that it will cost a lot of money to make Lao Wei laugh like this!

And......

Isn't it selling off again?

"Overhaul?!"

Li Liang was puzzled and a little surprised, perfectly catering to Lao Wei's performance.

Lao Wei raised his chin and nodded slowly.

"It's not a major overhaul, but it's about the same."

Lao Wei turned around a few times, turned the lid of the oil filler down, and flipped his palm so that Li Liang could see the inside of the lid, which had a layer of milky white paste on it.

Li Liang was taken aback, the oil filler is directly through the inside of the engine, and now this kind of thing appears on this cover?!

Then the internal condition of this engine can be imagined,

Terrifying!

Old drivers know that engine oil plays a role in lubricating and reducing wear in the engine, and can also prevent rust and corrosion, reduce the vibration inside the engine and play a buffering role.

If the engine is the heart of the car, then the oil is the blood of the car!

"This is called oil emulsification, once this situation occurs on the lid, it is said that the cylinder gasket is broken, causing water to enter the oil and mix, causing the engine to wear and tear faster, and the heavy responsibility directly damages the engine."

Li Liang took the lid and looked at it seriously and asked:

"You can't take a car like this, can you?"

Lao Wei nodded and replied: "If you can, you won't accept it, if you want to collect it, you have to reduce the budget of at least 3,000 yuan and then quote it." ”

Taking back the oil port cover from Li Liang's hand, Lao Wei opened the lid of the water tank again, and he could see the slightly cloudy antifreeze inside.

"And here, when the engine is running, check the bubbles at the water tank mouth, if the air bubbles at the water tank mouth increase when the refueling increases the speed, and the bubbles decrease when you release the throttle, you can also determine that the cylinder gasket is damaged, remember?"

"Remembered." Li Liang quipped: "Brother Wei, do you have a sister, I'll be your brother-in-law, right?" ”

"Roll the calves!"

Lao Wei tightened the two lids, picked up a piece of cotton yarn, wiped his hands, and walked towards the tea table.

"These are all experiences, in fact, no matter where there will be problems, it always costs money to repair the car, which is equivalent to increasing the cost of the car, when you collect the car, calculate the cost of repair, if the price is not suitable, and it is time-consuming and laborious to repair, then the car is better not to charge."

After the two sat down, Lao Wei added to Li Liang with a smile: "Sometimes, the price of a boutique car may be higher, but it is worry-free, and it is hard to sell." ”

Lao Wei's words made Li Liang fall into deep thought, especially the sentence just now, he was a car with 1200 yuan on the surface, and then counting the transfer fee, maintenance fee, refueling, etc., this is the cost of the car.

And it takes a lot of time to rebuild the car, and the longer the maintenance time, the later the car will go on sale.

What if you receive a boutique car?

You may only need to wash the car and hit the taxi wax to sell.

……

It was getting late, and Xiao Zhang began to pack up his tools, and it seemed that it was time to get off work.

"Brother Wei, let's sit down together, it's time for dinner."

Lao Wei waved his hand, "No need, there is something to do today, if there is any big work in the future, just take care of your Brother Wei." ”

"Good ......"

That being said, it always felt like something was wrong.

Li Liang said goodbye to the two and drove out of the compound with Xia Li,

In the rearview mirror, Lao Wei and Xiao Zhang waved their hands, and Li Liang honked his horn and turned into Xinbo Road.

Watching Li Liang's car disappear at the gate of the courtyard, Xiao Zhang muttered, "Master, his car doesn't need to change the spark plug." ”

"I said I needed it."

"So why did you charge an extra 50 yuan for working hours? Isn't the cost of man-hours added to the accessories for a small job like this? ”

Lao Wei smiled, took out a cigarette and put it in his mouth,

"It's tuition."

"Hey, Xiao Zhang, do you hear that? The three-way catalytic converter of his car may be scrapped, tsk tsk, don't tell him, almost half of his car price. ”
