I have an annoying rattle on my engine(2.0 gti 8v),its fine on tickover but at around 3k it develops a top end rattle and if you keep reving it dissapears.If i rev it up slowly its not as bad and is more noticeable under load.Its high mileage 157k but other than a puff of smoke at start up its fine,It is definately top end so can rule out big ends.
Anyone have similar problems before???
