2008 Hyundai Tiburon GS/Sport I4
Well I'm way under the mileage I may have put 40,000km on the timing equipment I only mentioned the 125,000km because that's what the warrenty that Dayco offers is but now the car has a whole new issue I'm so tired lol changed alternstor changed belts changed rad fought for few weeks with the timing now i think the bypass security thing I have In it is having issues maybe to do with moisture or water from it being cols and thawing but the little security symbol sometimes doesn't light up and it won't start then after i try a few times the light flashes car starts lol f*** sakes chasing kne problem after another with this thing. But ya I'm about 20,000kms under the change interval for timing equipment .Your first mistake was trusting Dayco. Your interval is and always will be 60k miles (or 100k kilometers) and not a centimeter more. The 2.0 might be more forgiving with odd brands but we always have recommend either the Gates or Aisin kit due to quality problems with other brands. We've been preaching this for 20 years now. I think your best bet is to eat the $90 USD on a proper Gates kit for peace of mind.
If you have to helicoil it then make sure it's done right. helicoils are stronger than the original base material anyway so that's not necessarily a bad thing. Good luck!
