I never mentioned intake valves....re-read the post...intake valves are your assumption. ...
Yes that was my assumption, because all anyone on the Kia/Hyundai forums ever talks about is that issue. I've never read a report from any source of carbon accumulation on piston tops causing a problem on any Kia or Hyundai engine. This forum has nothing whatsoever to do with Audi, or any other European auto make, and information posted about those vehicles have nothing to do with Kia/Hyundai. If you have information about carbon deposits being an issue on our vehicles, then by all means post that here.

You sure are quick to shoot someone down when you don't have all the facts or even read the post......
Your type never ceases to amaze me.
If YOU reread MY post, you will find out that I did not 'shoot down' your carbon tick idea in any way - all I said was that I have no idea due to lack of proof.

So yes, I don't have all the facts, and in the case of Kia/Hyundai engine issue root cause, I don't have any. And that's what I'm looking for on these forums - facts based on hard proof. So if you can find and post ANYTHING related to your carbon tick idea happening on a Kia/Hyundai engine, then I will respond to that. However, I don't get into pi$$ing contests, so unless you come up with documentation for Kia/Hyundai engines that supports what your saying, then this will be the last time I reply to you.

And very sorry that I'm not your type.

valve tick

Doing a online search. Dealers seem to be telling owners. That a Kia valve tick is totally normal. Which is what our local dealer told my wife.

How does a gasoline engine sound like a Volkswagen diesel ??

For 32 years, I have had many engines apart. From lawn mowers to Mack trucks.
With main focus on Chevy and John Deere.

The wife has a 2012 Forte. 122,000 miles.
Around 70,000 miles a slight valve tick started.
I told her maybe the injectors.
She took it in. They told her it was fine.
She took it in after 90,000.
Again told fine. But they did replace spark plugs.


The tick would go away or be very slight after awhile.
Now it is loud. Sounds exactly like a Volkswagen diesel.
Does not go away after warm up.

Seems like a tick not a rod knock
Stethoscope did not show anything abnormal.

I have not come across anyone describing a procedure to go through.
To try to locate / isolate the Kia { valve } tick

I am just amazed that a gasoline Kia engine.
Is supposed to sound like a Volkswagen diesel.
Which all owners are to except that as normal.

I find it hard to believe. That some mechanic, wrencher, or gear head.
Has not figured out what makes the noise in Kia engines.


Anyone have any positive results??

Not sure what's going on there, but camshafts that act directly on valve tappets Do make a clicking sound, which is normal. Is it one set of valves, or all?

There is nothing unique about a Kia designed engine. All manufacturers use the same technologies, part suppliers, and in some cases even the same software to control engine operation. If someone is experiencing this phenomenon it may very well be carbon tick. All the major OEM's have experienced it in their products at one time or another.

If you believe you may have engine carbon tick it won't hurt to add a bottle of high quality injector/ combustion chamber cleaner on top of a full tank of high octane (super) gasoline. Drive it hard for that tank of fuel and see if the issue goes away. All that will cost you is a tank of fuel and the cleaner. If it does reduce the noise, you have discovered the Red X and solved your problem.

I would do this test my self, but am not experiencing the issue......perhaps someday.
