My parents 2009 Sante Fe is the worst...it literally sounds like a bomb ticking from the time the engine is cranked to the time it is turned off no matter how warm it is

Thanks to all who answered, Agreed on the CAI and exhaust, I still hate the sound and figure ill drown it out with the exhaust lol!

i'm sure if the valve cover wasn't plastic it'll be quieter.....in fact are there any aftermarket metal valve covers!!!!!! i wouldn't be the only one keen on that!

I'm at 60k miles and i've always heard a feint clacking while idling. Also, I started getting a gurgling noise while starting and while accelerating/revving after the dealer did a coolant flush, but i'm about due for another oil change so I was going to get it checked out when i'm there.

It features hollow stainless-steel DOHC with powder-metal cam lobes, pent-roof combustion chamber and shimless bucket tappets in the cylinder head.

BorgWarner Morse TEC supplies the complete timing system which uses the company's proprietary silent timing chains. Continuously variable valve timing (CVVT) works on the intake side.

The aluminum alloy engine block, which is formed using a high-pressure die-cast method, has a unique Metaldyne-supplied cassette-type balance shaft module with a two-stage oil pump built-in. In the lower-end, the block is reinforced by a ladder frame. Other notable features include fracture-split sinter-forged connecting rods and a stainless-steel exhaust manifold.

Theta's EMS (engine management system) software is EMS-II from Siemens VDO and the 32-bit PCM (Powertrain Control Module) calculates the amount of intake air by utilizing a contamination-proof hot-film type MAF (mass air flow) sensor.

In the 2011 Hyundai Sonata and Kia Optima, this engine has Gasoline Direct Injection and produces between 198 hp (148 kW; 201 PS)-200 hp (149 kW; 203 PS) and 184 lb·ft (249 N·m) -186 lb·ft (252 N·m) of torque.

MPI version of the 2.0L Theta engine has a 10.5:1 compression ratio and it produces 163 hp (122 kW; 165 PS) at 6,200 rpm and 146 lb·ft (198 N·m) of torque at 4,600 rpm and is available in the Middle East.

MPI version of the 2.4L Theta engine has a 10.5:1 compression ratio and it produces 176 hp (131 kW; 178 PS) at 6,000 rpm and 168 lb·ft (228 N·m) of torque at 4,000 rpm and is available in the Middle East.

Where did you find this info? FYI our engines, here in the US anyway, are all run by MAP sensor, no MAF.

Iv'e had this same problem in mine as well. I have looked on this forum and from what I can tell the engine noise is normal. Lots of people from this forum have taken there cars to dealers and they tell them it is a normal noise with this engine. So I don't think you have anything to worry about.

when he pulls the accelerator pedal similar is the case but my sound is not very loud though it can be noticed!
If somehow the crank rings are slipped what kind of indications would that give, and about starting and pressure car puts nill petrol in engine in cold state however once start it creates no trouble at all if we switch it off or start it!

I purchased my forte about 3 weeks ago and like everyone else I hear alot of noise. The only differents is that I hear it almost anytime I am idleing. The car sounds really junky. I hate that I purchased a brand new car and it sounds jsut as loud as my old one.

actually i like my stock engine knocking it sounds mean


and is it just me or does revving it up when its warm to around 1.5-2k and letting go of gas quick make a fuel cutoff or something ? sounds good hahah
