2005 ain’t particularly old (at least I don’t think so) – you’re making my 2000 truck feel ancient man!
anyways – I always group my vehicle’s sounds, and rate them in severity –
7. body/trim
6. interior
5. exhaust
4. suspension
3. drivetrain
2. engine
1. legal requirementsthere’s obvious reasoning: you can’t drive without the vehicle being legal, and the engine works, then the engine can make power go to the wheels.
the successful aging of a car is entirely relative to it’s human. Are you a calm driver? where do you drive? highway? city? potholes? dirt roads? – my biggest observation is that 1 day of hard use on a car isn’t bad – but if you’re the type of person that sees a car’s purpose as such, then prepare for faster deterioration.
How to prevent? firstly stay on top of your fluids – they’re the first telltale sign to engine wear. then stick to your maintenance schedule.
when you find new sounds, it’s very important to find specifically where the sound is coming from, and group it in severity to its function (power steering for example)
yes engines start to make more noise as they age (not going to lie, Kia’s are not yet known to live a long time [the company is still young, no statistics]
mostly due to the expansion and erosion of piston rings, bearings, seals, etc. – some of which are easy to replace, most of which are not, and just accepted as noisemakers due to the cost and effort.
personally I miss the days when cars lasted beyond their owners. The automakers have realised that this is no longer a successful moneymaking strategy and have decided to make worse cars that require more service calls – because it makes money. however overall, your personality as a driver will equate to a longer lasting car.

whoa also just read that you have an integra – I used to have a CR-V (which has the same engine) – on a 2000 I don’t suppose you’re likely to have VTEC, however you very well might. if that’s the case I miiiiggghhhhttt suggest that your valve clearances are having a hard time adjusting at higher RPMs and perhaps only some of them are expanding fully during the “VTEC stage”
^ after reading that aloud I feel like a bit of an idiot but still seems valid. I could be 100% shooting in the dark but could someone verify that I might be onto something?

weird question, but are you driving with a large container of water or anything? maybe a hilly environment?
and howww noticeable are we talking here like irritating surges that would be embarrassing if you were taking a girl out on a date or like would only you notice it?
my guess is it has something to do with the engine reaching a happy equilibrium at a constant speed – something relative to air intake or electrical. maybe a lag in timing is causing the compression stroke to fire late – maybe check or clean your fuel injectors.
Or it could even be air intake – something relative to initiating combustion.
I would try driving your car for a *short* time with the throttle body removed (or maybe just air filter) – and then try a fuel injector cleaner.
^ think more along the lines of ruling out problems and isolating a particular issue that either exacerbates or improves your situation.

Hey Guys, so here’s an update (sorry video update hasn’t been working, will try again) – attached are some photos, one being of my timing belt cover pried back – as expected, the timing belt and pulley seem to be in fine working order, the belt is centered, and upon operation etc, there is no play or wobble. Underneath the vehicle, I did find the sound to be much more prominent – I think Eric nailed this one with the harmonic balancer, however I’m kind of curious as to the specifics – I mean the harmonic balancer on a V6.
Here’s what I’m thinking:
the sound does seem to mimick a tempo relative to 1/6th of the engine’s speed
it’s not likely to be a crankshaft bearing because that would likely be more constant (unless the harmonic balancer is placing weight on a specific part of the bearing)
I’m assuming the harmonic balancer is part of the crankshaft pulley
– but in all fairness, what could go wrong with a harmonic balancer?overall I don’t predict this to be a difficult fix – remove drive belts, transmission in park, wrench single bolt on driveshaft pulley.
Any advice? personally I am very relieved that I am sure this is no longer the timing belt – at which point I’m quite comfortable leaving the problem and adding the sound to the character of my car… 🙂

Awesome thanks a million Eric! is it common for a timing belt sprocket to be on a bearing? could it be the crank pulley bearing or similar?

Yea thanks a lot for the help, guys!
so as I mentioned, I removed all of the exterior belts (doesn’t have a serpentine, but alternator, powersteering, and A/C in succession) – and the engine still made the noise. I’ve managed to pry open a cover and get a peep at the timing belt – the sprocket is running true, and seemingly unlaboured, but there’ no real way of knowing unless I go allll the way in to the timing belt – which I could do, but it’s a bit risky given the winter environment etc, and the fact that I’ve never been that far into an engine before.
What is a balancer? does anybody know where that is on the VG33E?

sonofabitch you might be right. Coolant leakage- I don’t know if the water pump is driven by the timing belt or not- the PS belt drives the fan, and the fan is attached to the water pump, but the fan and waterpump function separately (like a freewheel on the same pulley) but i am noticing a coolant leak- I had to undo the coolant-pump intake in order to replace the idler assembly. But i’ve put it all back how i found it. how could the waterpump leak onto the timing belt? how do I fox that? I’ve got a photo of exactly this situation from the service manual… trying to upload it via mobile….

I would agree it’s not a strut issue. I just replaced all 4 struts on my truck (and to be honest didn’t notice a single change in the way she drives/handles) My suggestion would be an upper or lower balljoint or control arm bushing?
if it’s a balljoint you’ll here a very distinct kind of clunking when you hit a small or sharp pothole. a control arm sound would be noticeable more if you drive slowly over a large speedbump that compresses/extends your full suspension.
