Noticed recently that at high revs in any gear or on idle my engine is making a high pitched whine, whilst the gf held the revs at 3.5k it sounds like its coming from the cam area... vague I know. I had the belts changed at 519 just over a year ago but only recently noticed this, ill try and get a video up but its loud enough for me to start noticing it unless im getting extremely paranoid all of a sudden!
