I'm an owner of a 2000c DOHC Sportage 1996 UK model with 90,000 miles on the clock.

Sometimes I get a metalic ticking sound at idle and only when the engines at normal operating temperature. This normally mainly happens when re-starting the car after a short stop, it has also happened when in traffic but only on tickover. What do you guys think this could be? And what solution?

hi,
ok the noise is tappets, this normally happens when there is a air pocket
in the cup, cure this by running engine at 3000 rpm for about 10 minutes
should cure problem, the other cause is using wrong oil grade??.

or a lifter might be sticking.
change the oil run a higher octane fuel.

Or do nothing. Those noises are pretty much normal. Especically after a hot restart.

Just make sure the oil level is good and the correct viscosity.

Thanks guys, pretty much knew it was tappets. Is it just as simple as an oil change? Is it worth using an engine oil cleaner lubricant to flush the old oil out of the tappets and then replacing it with a good quality synthetic oil? Or will it do more harm than good?

Just thought I'd update.

Did an engine oil flush and refilled with semi-synthetic oil, nothing has changed! I still get this ticking and i'm convinced it not comming from the tappets. Noise seems lower than the cylinder head and right at the front of the engine, roughly where the cooling pump sits. Is the cooling pump driven from the cam belt or V pulley?

Any Ideas?

Hello HighTower, I have a 98 Kia Sportage and since I bought it has done the same thing yours is doing, that slight ticking at idle. Usually when it gets worse after warm up it means rods or mains bearings are worn out, try running a bit of lucas oil stabilizer. Also while its running, slide underneath of it and listen to the catalytic converter, the one downstream. Chances are your noise is really coming from there though it sounds like an engine problem. Many of them have that problem though Im not exactly sure what it is though if it is coming from the converter its nothing to worry about, simply a nature of the beast habit. Hope this helps you out a bit
