The Toyota Corolla, which can't be broken, has finally broken down, and it has run 190,000 kilometers in 17 years, and this time it will be overhauled

My old guy who can't drive badly has finally entered the repair shop, and this time it is an overhaul, and a few days ago it was on the highway, and there was no speed directly.

I didn't drive it, our students drove it, and they drove on the highway, and they just didn't have speed, and he said that he couldn't refuel, and then the car couldn't be ignited.

I saw a bunch of faulty lights, then the oil failed, then the engine failed, and I figured something was wrong.

And then dragged it back, dragged back from Yiyang, it took a lot of effort. Dragged back now just dismantled the cylinder head, disassembling the cylinder head is the above section.

Then I found that this is the timing chain here, there is a screw out here, this screw should be broken, just evaluated, 8 percent may have to overhaul the top cylinder.

Oil coke is severe

Now let's start to dismantle it, in fact, I didn't change the oil very badly, but this situation is not too good. Because when this car was in my sister's hands before, it was driven by their children for more than two years.

The kid has been trying to find a reason to change the car, so it is said that he drove 40,000 kilometers without changing the oil, just to break the car, but it didn't break down later, and if it wasn't broken, it came to me.

Therefore, if you do not change the oil for a long time, this kind of coking will become very serious. And at that time, it was estimated that the oil was changed, and it was also a very poor oil, and I don't know if there was a fake oil. So this engine is actually very carryable, and it is said that it is an engine that cannot be broken.

I have just removed this oil pan now, it is not in good condition, maybe in the process of opening, it has appeared and the oil is not on, and the oil lamp alarms.

Then, all down there, I saw a lot of shiny and shiny metal chips, and maybe the tiles inside were almost polished.

summary

Today, the heart, the engine and the gearbox, this piece was finally removed.

After the demolition, now it's just a matter of waiting for tomorrow to continue to break it down and see where the reason is.

The reason has not been found yet, because the oil suction port is not blocked, but a lot of metal chips are deposited in the oil pan, and many metal chips are fresh, so it should be that the tile inside is worn off.

After grinding it off, it all sank to the bottom, so we will go to tomorrow, continue to the next step, dismantle the engine, and find the cause after dismantling, anyway, it must be more injured inside.
