The Sportage over time does start to have valve train tick. This is a known problem and you have to adjust the valves to get it to stop completely.

Using heavier weight oil or an oil filter with a silicon anti drain back valve helps.

One thing I've started using is Lucas Oil Stabilizer which works really well.
