<br/> I have a S60 Volvo with 105,700 miles and recently got a full maintenance done, my car was working fine before the maintance, but the Volvo repair shop said that at 105,000 miles it is important to get a "new timing belt" put in and for me to get my breaks replaced as well. After all of this was completed, they said that there is nothing wrong with my car and that they checked everything on my car. The next day my car began to make extremely loud noise when I pressed the breaks and when I put my car in park. I waited another day to see if the problem still occured and it did. I took my car back to the shop and they said that my "breather box" had a hole in it. My car has not leaked oil either! I think that they did not seal the valves properly when they replaced my timing belt and is causing the noise that I am hearing. Please help..... They are saying that it will cost $700 to replace the "breather bix" and I think they caused the problem........
