Today, there's a ford in the factory with 2. 3 loads, and the owner of the car has said that the oil leak in the gas chamber has been repeated several times, two gas chamber mats have been replaced in five years, three gas chamber covers have been completed, one of which was specifically a aluminium. The oil is still impenetrable。
And when i opened the hood, the sight was really funny. It's not the usual oil spill. It's all over the gas chamber. It's all over the air filter
Looking at this oily engine, i know it's another misdiagnosed case. Many repair unions customarily believe that oil leaks in gas chambers are mats that age or lids that change, but the problem is often less simple。
This ford win 2. 3l engine, using the duratec series engine, which is a good one to tell the truth, but by a certain number of years and miles, there's a general disease. Guess what? The root of the problem is not in the airlock itself
Based on our maintenance experience, the problem is rooted in the grinding of the engine cylinder, which leads to a chain of pressure in the cylinder, so that the pressure in the axle box increases exceptionally. When pressure is overstretched in the axle box, the engine oils find their way through the pressure, and the relatively weak airlock covers naturally become a major disaster area。
Think about it. It's like a man's internal pressure is too high. It's not the mask, it's the pressure in the body. In this case, you're changing 10 gas chambers, using a nice seal, and you can't solve the problem。
I remember one time, a teacher said to me, "the engine needs to breathe, and if you don't let it breathe, it needs to be snotty!" this was the case with the victory of the ford, which caused a loss of balance and high internal pressure due to the problem of the cylinders。
Speaking of which, some masters might have thought of checking the pcv valve. It is true that under normal circumstances the pnv valves are used to regulate the pressure of the warp axle cylinders, but when the cylinders are worn out, the pressure is far beyond the control capacity of the pnv valves. It's like running smoke from a fire workshop with a small exhaust fan, which does nothing。
So, how do you figure that out? In addition to observing oil spills, the gas tank pressure can be measured and the engine compression ratio examined, which will tell you the truth. Sometimes the experienced teacher knows the extent to which he listens to the sound of the engine, then combines it with the amount of gas that travels on his feet。
In the face of this situation, the only cure would be to overhaul the engine and address the problem of air-cylinder grinding. As soon as i know that, the first reaction of many drivers is, "does a leak require a major engine? Isn't that the pit man?” indeed, this maintenance program sounds a little scary, as if you had a cold and the doctor gave you a chest opening。
That's how the owner of today's car heard the engine had to be overhauled and his eyes were staring at him. After all, the car had been in place for some years, and after a combination of considerations, he had found no major repairs and had finally opted to give up maintenance. As repairers, what we can do is tell the truth and leave the choice to the owner。
In fact, i think it's not how much we make in the car repair business, but what's important is that we be able to afford our skills and trust the owner. If you know the airlock covers won't solve the problem, you'll have the owner trade it for it
Therefore, in the event of repeated oil spills in the future, it is recommended that you be more careful not to rush into the gas chambers and to make a thorough examination of the root causes of the problem. If the gas tank is a problem, it is important to make it clear to the owner that the change of the mattress can only be a temporary relief and treat the symptoms。
In so doing, even if the owner chooses to use a new mat first, at least he knows that the problem may re-emerge in the future and will not blame repair plant technology. To put it bluntly, this is a matter of good faith and is the foundation of our business。
This case is shared here today, and it is to be hoped that you will be able to make less detours in dealing with similar problems, not to allow the owner of the car to spend his money and not to misperceive his/her work. If you can't get rid of the disease, you can fix it
