Loss of power and pulls Mondeo tdci 130cv

Hello everyone, I have a 2.0 TDCI-1130CV Mondeo, year 2002 manufactured in Spain. It currently has 240,000km. When I was 5 years old, I suddenly noticed a loss of power (if it is required, but it costs it more than normal), followed by a blow from the turbo when accelerating and pulls around 2000 rpm. I took him to the Ford and told me it was the intercooler sleeve. They changed it and like new again. Year and a half later the same symptoms returned. Back to the workshop and same diagnosis. As the guarantee of the replacement piece was one year old, again paying and walking. Now, almost two years after the 2nd change, the breakdown has been reproduced. I don't want to have to go through the workshop again to saber me 200 Euracos again.
Can anyone tell me how to identify the happy sleeve and if you can change without having to go to a workshop? Please ...

greetings,

The sleeves are going to be raised because they are the ones that leave the intercooler and go to the turbine. Bush the radiator of the intercooler and you will see the sleeves are always supported both, or if you do not turn on the car and when you accelerate it, you will hear it an escape (blowing) from the hose that is broken the sustainment of them are not difficult.

Thanks short circuit, today I will take a look. By the way, you will not know where I could find a step by step how to replace them. The most that I have done so far is to change the battery and brake pads, and I have doubts ...

Well, nothing, I have disassembled the sleeves and nothing at all, they are in perfect condition. I have also proven that the blow is not noticeable, it is only perceived when you circulate. Is it possible that the breakdown comes from another element?

Does anyone think of anything about this breakdown?

I have proven that the blows are only noticed when accelerating, they are not perceived if the speed is maintained. Nor are they noticeable, only when the vehicle is going.
Another doubt that suggested me when I disassembled the intercooler sleeves, is that their internal walls were impregnated with oil, and I don't know if that is normal or not.
All the information you can provide will be well received.
