Although I have lost the link in Korea to this information, Kia announced that both the new 2.4 and new 2.7 engines are equipped with timing chains instead of timing belts. No mention of maintenance schedule for these chains.

there is no maintence schedual for replacement but the from what they tell us in training that the chain should be inspected at 100K but that is not an official remark, as far as i have seen there is no printed specification for inspection or replacement

2.7 V6 is still a belt, with 80k service interval.
2.0 and 2.4 Theta engines use timing chains.

Not according to Kia's HQ in Korea or my service people. The old 2.7 was belt driven but the new one is chain driven.

The KIA Tech training course I was on last week must be incorrect then

2.7 is a 'long like' belt, 80k mile intervals, 100k miles spark plug intervals.
It is a very different 2.7 than previoucly seen in other mdoels.
