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.

The DOHC has hydraulic lifters which are self adjusting, in fact there is no way to adjust the valves short of rebuilding the top end! The hydraulic adjuster may be gummed up, try some seafoam or other quality cleaner in the oil, GM makes a good top end cleaner I just can't remember the name right now!

It may not even be the lifters, I had the same sound, and it took the dealership a month to figure out what was causing it, turned out to be a intake valve that was not completely closing on it's own and then on the compression stroke it would snap closed causing the tick! If it hadn't been a warenty job it would have cost me well over $3K as they had completly rebuild the top end, new valves and re-grind the seats etc!.

Another possible cause could be a pin-hole or crack in the exhaust manifold down pipe, an exhaust leak is commonly mis diganosed as valve chatter.


Hi, I think I have the same problem with my 2000 sportage,I noticed a ticking sound when it idle at 750-1000rpm and it stop ticking when engine reach 2500+rpm

Im using 0-40 synthetic oil (could it be the cause?) and my oil filter doesn't have anti drain back valve.

My exhaust manifold is cracked and I have 0422 CEL code on(CAT), can it be the problem?

What should I start to look at first?
