Just after having fixed the fuel leak at the fourth injector, raising the fuel pressure and replacing a couple of broken water tubes, when the engine is above the 70 - 75 degrees {not when is colder} I hear a strange noise, something like fsssssss, when I pass the 4700 rpm in all gears and this noise is getting stronger as the revolution goes up! Seams that is coming from the right side of the car but I can't locate it.
Any suggestions?
