Hello Ladies and Gents

I can hear the noise when revs are at 1600-2000 . Normally its not noticeable but I can clearly hear it when parked next to a wall or a car.

Please check this two links
1) Engine bay http://www.youtube.com/watch?v=XtDUvRdH5U4
2) From inside the car http://www.youtube.com/watch?v=elcxPPE181A
I hope its something cheap to repair.

Gen 3.5 2.0 22k miles
Oil changed every 5-6k miles
Owner’s manual recommended oil is 5w20 or 5w30
I’m using 5w30 Amsoil
Oil level 75% max, I had it at max level but no change.

Thanks for help

Hi
Unfortunately no, I haven't found what it was, but I've tried hyundai-forums.com, 1 reply so far:

''Thanks for providing the engine mileage. The noise you are hearing is normal for a car using 5W30 oil. The thinner viscosity give you better mileage and higher revving, but a higher viscosity oil will muffle the tappet noise better. You could try STP Oil Treatment to quiet the engine, but I am quite sure you have normal engine noise based on your engine bay audio.''

hope there is solution for it, because this noise is quite embarrassing.

There was a post some time ago describing the same noise:

...Basically when I rev the engine above 1,500rpm, all I can describe it as is like a ball bearing rattling round an empty tin can sort of sound coming from the engine...
Androo007

The only difference is that I can hear it from 1100 to 2000rpm.

In my manual Hyundai recommends using 5w20 and if this one not available then 5w30.

Sounds like your hydraulic tappets to me. And because it's a 2.0 Beta engine your timing chain is probably rattling a bit too.

Cancel the first bit, I'm a nob - 3.5's don't have hydraulic lifters.

ADD-IT do a good hydraulic lifter treatment. I put some in a customers Gen 3 a while back and after a day or two the noise had reduced significantly.

yes te cost for a set of lifters is nearly 500 pounds i made enquiries for my car! but like i said earlier in a post i flushed it with stp flushing oil then changed the oil and filter and its fine now!
could just be a sticky lifter thats all! give it a go dont cost much to do! and better than paying out loads of money!! put 10/40 oil in!!

Ok, I'll try the stp engine flush, but is it safe for the engine?

yes i just done mine its sweet now and mine has done 139,000 miles was really nosiey before!

Inital "ticking" (as I call it) is fine when its cold, as the oil has probably drained out of the tappets over a period of time, (overnight), obviously when you first start up the car, the oil starts to go around the engine, and fills up the hydro`s (tappets) then they should go quiet, also as the oil heats up it gets thinner, so it fills up the tappets faster, the video on this topic is obviously showing this is not happening, my previous post on this, is all based on the assumption that the car has the correct oil in it, has had a regular oil change, etc..etc...etc...

If it has`nt then we could start going down the road of "worn" cams, etc. but we should stick to what we know and can "hear", engine flush can help, but all that trys to do, is clean out any deposits that maybe "blocking", this can be, the oil pickup pipe, a blocked tappet (though the chancies of this happening is like 1-10,000), oil filter maybe blocked? there could be a number of things that could be causing this, however (unless you got loads of money to burn, which i dont think many have at the moment) you could go through the entire "oil change, engine flush, new filter, oil treatment, hydrolic treatment fluid, valve conditioning treatment, etc..etc...etc...) total cost at least £100+... (cheaper to ask a garage to take alook).

**WARNING DISCONNECT THE BATTERY BEFORE DOING ANY ENGINE WORK TO PREVENT INJURY**

However, lets get our hands dirty and save a few quid, we have taken an estimated guess that its the tappets or timing chain, so take a look at the timing chain, and check the tension on that (see the manual for correct tension) if that seems ok, then the next stage is to take off the rocker cover, and then manually turn the engine over with a spanner or rachet and check each tappet with a gauge, though by the sounds of it, you will probably able to see which tappet is failing if its a tappet that has given up, if you cant, then as you manually turn the engine over, check each "hat" on the tappets to see if they are "popping up" as the cam leaves it, (note this will probably only happen once as the oil drains out), if you see a tappet that doesn`t "pop" when the cam leaves it, then this is most likely the damaged one, and will need replacing, I wouldn`t buy a "new" set if you can help it, as the cost is extreme, instead I would check e-bay or keep an eye on here, for an engine thats gone bang, and get a replacement tappet from this instead, should be cheaper.

for those that have a "bare`able" noise from there engines, do an oil flush, and get some "good quality oil", magnatec for example, yes it is expensive compared to the other oils, but £30-£40 once a year isn`t that bad when you consider the costs of doing the above. (engine treaments like SDP etc) is down to personal choice really, but if you use something like magnatec then you should`nt need any oil treatments to be added, lastly as a "tip" when you do the oil change, get a clean bit of "white cloth" (net curtains work well for this, but dont let the wife or your mum catch you using her best ones from the airing cupboard... lol) on the "old" oil thats come out of the engine, do a couple of "swipes" through it with the cloth, and see how much "debrie" it has in it, MANY MANY MANY people do an oil change without checking there old oil, and then go on to the next year for there next service, if you have a "fair amount debrie" in the old oil (large'ish clumps, or gritty bits), then do another change after a couple of months, dont wait for the full year, it is a "wise" idea at this time to use some "cheaper oil" if your gonna do another change after a couple of months, as you dont want to go throwing away a £30-£40 bottle of magnatec after a couple of months on a change, wash/rinse/repeat untill your happy with the condition of the "old oil" then use magnatec for the final change, you will have peace of mind then, that your engine is reasonable clean and will hopefully function for many years to come without problems.

Long post I appologise for that, but hopefully it will help some of you out there.

PS. read my siggy...

I've found a youtube video, same problem but different car (hyundai accent)

mmm listening to that other clip ts sounds similiar to our noise. i wonder if all gen 3.5 owners have this noise and not noticed it or is it just us being fussy.either way im not convinced its a "normal" noise and have e-mailed hyundai now to see what they come back with. if the dealer had said "thats normal its the so and so valve or whatever then maybe could have believed them but to say its normal without giving a cause or reason for it makes me wonder. seems like the dealers dont want to get involved.i took the rocker cover off today and checked chain tension seems ok not flopping about and the valve clearences seems close giving the wide spec hyundai manual gives so none the wiser .

Unless they perhaps fitted solid lifters for 3.5 gens, (maybe sharky would know this), I wouldn`t be happy with that noise at all, solid lifters by default make more noise then hydro's, but to be honest, if it was me and I had brought the car, then I would'nt be happy with this noise, over time its going to get louder rather than quieter, unless as I say they are solid lifters.

My concern would be now, that if i kicked up a stink to the dealers about this and in the end got them to take a look at the lifters, they "May" try the short cut approach and slap in thicker oil to quieten it down, obviously not the best approach... IF you can convince the dealership to inspect the lifters, then I would insist on being there at the time if possible, so you can watch just to get some feedback from the mechanic as he/she inspects it.

The other "possible" option maybe, is to go to an hyundai main dealer, and see if they have any gen 3.5 in that year on the forecourt, and ask them to fire it up and take a listen, (if you can get more then one to "view/listen" too, the better, then you can make a comparision to your own).

I really cannot see to be honest that the "noise" you have is or could be classed as "normal" from any dealer, as buying a car the first thing your going to notice is the bodywork and engine noise, has the car always sounded like this when you first got it? or has it gotten louder as time has gone by? see if you can perhaps persuade the dealer to take a look at the lifters, also try and listen to some other makes with the same year and see if you can perhaps decide once and for all that this is not "normal" and then you can persue your case with more justification.

well, dropped it off today and picked up the loan car well i say car its a 1.1 getz. they had another coupe off the sane age on the forecort so asked to start it up from cold to have a listen and it made no rattle at all proving to them that ours is not a normal characteristic of the car so might actually get something done this time.

my bro's f2 evo made the same noise, noticed it was pishing oil out the rocker cover so we replaced the gasket and changed the oil, and the noise is gone....i would say it sounds like a "lazy Tappet" and thats its not gettin enough lub where it should be. these noises are always a bitch to place but from experience i'd definatley recommend checkin the rocker cover for leaks, Front and back

gonna keep an eye on this topic as my Gen 3.5 2.0 has same problem its only done 9500 miles with service every year its an 06 plate...

Had a mechanic mate listen to this tappet noise today he did the screwdriver test listening through the handle with the tip on injector rail reckons the noise is worse on the rail! Gonna see if i can get the car to local dealer and do a cold start on it they said they would have to do it this way.Last time they looked at it they couldnt hear the problem

i had a listen to another 06 plate with 24k on it and no noise whatsoever on cold start up and when warming up there is more to this than normal if only some make the noise??

hi glassman, let me know if you take yours to a dealer and what they say/do they might know what causes it as my local dealer not exactly confidence building at the mo. if they change something and it cures it then will know what it is.cheers
