Two doubts, golf mkiv, intercooler and wheel

Hello, I have broken intercooler again, I lose oil, I already take it to the workshop but again, I am thinking of changing it myself and my question is ... is a lot of hand to replace this piece, ??
The other doubt that I have is that the right front wheel moves, by chance they change it by puncture and when the wheel does not touch the moving from left to drch as if something was sounded or with slack-
I like the mechanics but I have no very idea, that is why I will go to a rental workshop that also advise not the fence to shit, thank you.

First in the intercooler there should be no oil if there is the problem is the turbo and if you have no idea that is quite delicate you can load the engine, second of the wheel if they are not the wheel screws do not walk with the car, you can fall to the ground if it is a trapeze and you can have an accident, better see a confidence mechanic

Hello, in the intercooler I have oil, I already happened to do more than 5 months and in the workshop I told me that it could be repaired, I do not need to change it, that is why I believed that I could do it without much complication, now if the oil in the intercooler is the fault of the turbo because I do not know that I

repair me Your help

I imagine that I repair you the turbo because the intercooler is just a radiator that cool the air, if it has oil it is from the grease of the turbo that the seals are leaving and put oil but repair them is very difficult it is better to look for one in a scrap or buy a new one but they are expensive, better look for someone to eat,

Hi again, yesterday I went to the workshop and the mechanic told me that the wheel clearance is due to the direction, the direction is slaughtered, the 2 wheels move, and with respect to the intercooler it does not seem that chorree, it is seen that the losses I saw were from the previous one, thanks to you
