OK my first real(maybe not,hopefully) problem with my carisma 1.9 di-d 2004.
Its done 145k now nothing major gone wrong in the past,well serviced,clutch, airflow meter and usual stuff.
Now when i accelerate i can hear a rattle which you can only hear at 3000 rpm in 2nd and 3rd,it maybe there in 1st 4th and 5th but engine noise may drown it out.
this isnt a loud rattle and goes once i pass 3000rpm,sounds like a fast but quiet drum roll being played on a tin can.if i push my gear stick to one side or the other it quietens down and even stops stops sometimes but once i let the gearstick back into position it is there again.there is no rattle if car is in nutral and i rev the engine to 3000rpm,i cant hear it if i drive and open the window so im guessing something from the linkage to or in the gearbox.
i considered the cam belt tensioner but that was replaced 20k ago with the belts.
Any ideas ??
