Hello,
I have a kia sorento 2012 2.4 mpfi (Not the GDI engine), manual transmission, the car works and runs fine, but there is weird noise that comes out of the engine bay at 2000 RPM its like lifter, knocking noise, but isnt lifters supposed to be present at all rpms ?
anyone had any similar issues before?
Regards,
Sari
Can you please make a YouTube video of the noise and post the link here?
Yes make a YouTube video and post a URL here and we will listen
Hello,
i have a weird tapping/ticking noise coming from the engine, the car drives fine, no oil lose between change intervals, the car has 249000KM, and its manual transmission, engine is 2.4L mpfi not GDI.
The tapping noise comes from time to time, does not matter cold or hot. Oil inside is conventional oil 5w20 planning to move to Full Synthetic 5W20.

Those are some of the worst cars ever made. And the engines are known for catastrophic failure. I'd say you're lucky the engine made it this far.
Get rid of it!
these engines were recalled several times. They often don't make it past 60k miles. You can try checking your VIN and see if Kia will give you a new engine, but from what I hear they don't treat customers too well. Now we know that Kia knew about the problems and ignored them.

Kia also told NHTSA about a recall of more than 618,000 2011-’14 Kia Optima, 2012-’14 Sorento and 2011-’13 Sportage vehicles because the Theta engine bearings wore out too early and caused the engines to seize.
It's a primitive engine without hydraulic lifters so clearances need to be adjusted every 60k miles (if the engine doesn't blow up first).
Yours could be totally rattled out.
i know those issues where in the GDI 2.4 model, but not the MPFI? are you sure this engine has no lifters ? and the engine does not loose oil at all !! i've driven it for 5000 km now and still no oil lose at all.
The GKFE uses bucket tappets. Look it up.
It doesn't matter if it doesn't lose oil. That just means the piston rings are sealing. The engines contains many other parts that can fail. You may already have a failed bearings which is causing things to clatter inside the engine.
These engines were assembled with very poor quality control. Reports say they get metal debris floating around which causes premature wear and failure. Those hundreds of millions of recalls ... were for YOUR exact model vehicle and engine. Kia had to pay some pretty painful fines for causing the issues, and then ignoring them.
That's about 150K miles. If the video is at 2k rpm then it's much slower than a crank tick which you would hear 33 times a second or a valve tick you would hear 15 times a second. It's odd it comes and goes. Just make sure it's not a belt tension-er. I have been fooled more than once when the tension-er developed some slop or alternator drive belt was worn. Check the power steering pump has fluid and isn't sucking air.
