I have an mi16 engine in my 205GTi and for some reason at a certain throttle position it makes a squeaky almost whistley sound... when i bought it i knew the cam tensioner bearings needed changing which i did as they squealed at a certain RPM,
So i changed those which did the trick however there is still a noise coming form the engine bay when my foot is so far on the throttle, its not at a certain RPM and the noise does not change pitch at different speeds.
Its really bugging me lol and i hope iv explained it well enough so i don't confuse anyone...
Any ideas would be much appreciated to save my sanity .
