K11 Micra 1.0 90k miles. Has a timing chain. There is now a noticeable "chatter" from the engine when in top gear, at medium to high revs (60 MPH plus). Not present at high revs in other gears. Not present at startup, when idling or at low revs.
Recently had an oil change, which improved it slightly. Car drives well otherwise. Is this chatter due to the timing chain or just normal valve noise due to a 90k small engine?
Thanks, Bruce
