Hi, I have an '06 Rio5 automatic hatch which has the same motor as the new Accent (1.6 Alpha CVVT).
It has always had some piston noise when cold and I realise that's quite normal but just recently I've noticed a piston noise (sounds like just 1 cylinder) even when hot.
This occurs at around 1700rpm under light load e.g. coming up a long, slightly inclined driveway at about 15kmh. It's not pinging as I use
95RON.I always drive the car with consideration and ran it in carefully. It's due for its second oil change (15000ks) and I supply my own oil to the dealer (Castrol Magnatec).
Is this condition more than just an irritation? Could it cause premature engine problems? (out of warranty of course!).
Should I push this issue with the dealer before my warranty runs out?
Do you think a different type of oil may lessen the problem?
Like everyone else here, I appreciate your presence on these forums.
Thanks, Rick
