VE SS-V UTE 2008 Engine Noise Under Acceleration

[tpmax]

Hi,

So I've been having an issue with my 2008 Manual VE SS-V UTE , There is a noise under acceleration, sounds a bit like a high pitched rattle or pigeon noise. Seems to happen when the oil temp is above 106 degrees, wont make the noise when cold.
The story so far. The dealer has replaced the tailshaft (under warranty), The noise didn't go away. The head mechanic at the dealer tried telling me the engine was pinging which it wasn't, as all I ever run in it is BP ultimate. So I rang customer assistance and they got the district service manager to take it for a drive. He said it was the crank shaft resonating and that the bearings needed to be replaced and machined to a tighter tolerance, this was done and I was told before I picked the car up that the noise was definatley gone. I drove for 10 minutes and the noise came back. I rang customer service and they said that the district manager beleived the noise to be normal and a characteristic of these cars. Which I didn't beleive. I had another mechanic look at it and he beleived it to be the clutch "squaking". I am really fed up and I want the noise fixed. Customer assistance have basically told me I am stuck with the noise and the car.
Does anyone have any ideas as to what the noise could be?
Cheers
Tom

If you find a fix.. please let me know. I have had this issue for 3 years with zero results.

[tpmax]

yes its driving me insane, I have noticed its not as bad when the fuel tank is almost empty.
have you taken yours to the dealer?

[ASAUTE]

It's a dry gear in the fuel gauge needle, wd40 will sort it out

[tpmax]

no its not.

my mates cars been doing the same thing if you get it fixed or find out what it is would be much appreciated if you post hope you get it fixed to

[tpmax]

yeah its very very annoying,
im gunna take it for another opinion, I just can;t beleive that the district service manager believes the noise to be "consistant with a V8 Burble" I actually took a journalist from caradvice for a spin in it, and if the issue isn;t resolved they will contact holdens PR deparment.
Interestingly the noise seems to be worse when I have a full take of pertol, but it can;t be anothing to do with load as having a passenger with an empty tank would = roughly the same amount of weight has a full take with no passenger. and the noise doesn;t seem as bad when i have a passenger with low tank.
I;ve also been told to try W10-60 (currently castrol w10-30) oil in it as this would have a greater viscosity at higher temperatures and the noise doesn;t occur until the car has reached operating temperature.
Has yoru friend tried anything?

What does it sound like? So I can try and see if mine is same - my previous car was a BMW 6 cylinder so I don't know what is correct sound or this prob sound

[tpmax]

Have a listen to the noise, you can hear it very clearly around the 17-18 second mark, the quality isn't too good as i recorded then on my phone.

[TinSnips]

yep.. that's the noise. Exactly. Would you mind if I took this recording with me when I take my car in next Tuesday for yet another clutch issue?

[tpmax]

yeah take it in and let me know what they say,
I have had one mechanic tell me it was the clutch. but holden were reluctant to take there adivce.
How many you of have this noise?
if we can compile a list of people with this complaint we might be able to create a bit a "noise" and get something done about it.

[TinSnips]

It's not clutch. I'm on my 3rd. I'm starting to think it's a vibration somewhere.

[tpmax]

Well I have been told it is crank shaft resonance. also was told it was tailshaft vibration. (but these were both fixed/replaced)
how worn are your engine pulleys? could it be a slight missalginment? also what engine oil do you run?

[TinSnips]

No, tried that path too. Have had a few balancers, p/steer pullies, etc - all alignment has been checked a bunch of times.

I run 5w30 Anglomoil full synth.

[tpmax]

have you tried anything like a 10w-60?

[TinSnips]

no mate. To me, quieting a vibration is not the same as fixing it. I have always kept to factory spec oil, for warranty purposes - not that that is so much of an issue now! I'm not sure what they'll be able to turn up, if anything - but it's intermittent on mine - meaning it happens when i'm driving on my own, but not with a tech. Go figure.

[tpmax]

yeah i've managed to get mine to do it with the road tester and then with the mechanic in the car. i also let a non holden mechanic have it for a few days and he heard it. Maybe i should just flog the car off to a dealer and get another one.

[TinSnips]

Only been able to replicate it at one dealership - who couldn't diagnose anything else either, so a bit of a pointless venture.

In the video at the 17 second mark (I did hear it from the 10 second mark), are you talking about that metalic tinkling sound?

Are you in a specific gear when it does it or does it happen in any gear? I think if it was your clutch you'd almost expect to have other issues or symptoms, same for any internal engine issue. If the crank bearings needed replacing I think there'd be some cold start knocking....

Sounds like your car has an aftermarket exhaust, I would be going over all connection and mounts. If you've had an aftermarket exhaust fitted (or not) check to see that all O2 sensors are done up tightly. They have a washer on them that will rattle on the exhaust making a racket.

You said they replaced the tailshaft, did they check the centre bearing? When you have a load in the car does it do then or only when there is 1 person?

[TinSnips]

Any gear, pushing through ~2700-4000 rpm or thereabouts.

And yep - that's the sound. Almost like a fluttering or resonance. Hard to describe.

maybe check the cats, there have been some reports that they have been dying prematurely and or the exhaust heat shields

[HEXEM]

I just noticed at the very end of the video when you downshifted the revs would have been as high (if not higher than the exceleration) however there was not rattle....

Therefore it is some characteristic with positive load on the engine. Its almost like the rumble from the exhaust reaches a certain harmonic and vibrates something loose on the car... It is hard to tell though by listening to the audio recording and not be a tech.

How is the shift selector, is is loose or tight all the time? does it vibrate at the same time as the noise? Try holding the shifter tightly in a downward direction when excellerating and see if you get the same result...

I have found over the years that you have to pretty much do your own trouble shooting before you walking into a Holden service centre to have something tricky fixed. I'm not saying they are all like it, just been my experiance. If a little computer doesn't tell them what's wrong they basically say wait till something breaks then they'll know.... There are some good holden techs out there just few and far between unfortunately... Sign of the times we live in.. The disposable society...

I know it's a long shot... Do you guys have aftermarket extractors? Hit exhaust hard?

[TinSnips]

Going from my experience with this noise - stock exhaust and haven't found anything loose - though haven't checked cats to date. Shifter feels fine - holding it has no bearing on the sound - the sound seems to come from in front of the dash - but the resonance of it makes it deceptive. VERY unlikely to be gearbox or clutch related as both have been replaced a number of times.

It is at its loudest under load - and heavier than average acceleration (though you can hold the revs and it will continue at a lower volume - never when just revving or downshifting. Has to have load) - though not necessarily belting it. Has to be up to temp.

Agree completely with the state of the techs. Good ones are few and far between - but they are around.

Not sure about Tpmax - but mine is still stock and it's happened basically from new.
