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
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.
