02 VTR rattling noise under lift off? - new video with noise!

27th February 2012, 09:23

Hi
My Saxo VTR 02 plate on 70k miles makes a rattling noise
It occurs sometimes at idle but most commonly in third and second in hard acceleration at 2-3k rpm, as well as lift off coming back through that rev range
I know it's not the manifold heat shield, because I've removed that!
Read others list it as: engine pinking/centre section baffles/under car heat shield/engine mounts

Anyone shed some light?

Thanks!

resonator ?

Original air filter setup has been removed, can be the resonator then?

27th February 2012, 09:36

could be though not sure...I've heard it rattling in that rev range before, especially when letting go of the throttle back to 3k and under.

Any ideas how to sort it?
My air filter now looks like this

Where is the resonator!?

27th February 2012, 09:40

the resonator is normally located under that air filter pipe, can't really tell from that pic if it's still on or not :/

Also since you have non factory covers in there: check that everything is nice and bolted tight. Including the rad and fans since you seem to also have changed the factory one for a double, and the frame.

Sometimes you just hit the resonance frequency at a certain speed and revs and it rattles, the joys of owning a saxo...

27th February 2012, 09:42

That better?
It is just the piping you see that is present
I shall check the covers
But it sounds very metallic, carbon fibre wouldn't sound like that surely

27th February 2012, 09:45

Seems like you don't have the resonator anymore, it should be under the pipe that's under the torsion bar. Is it making that noise while stationary or while driving, because you could find out by revving while you're under the bonnet maybe?

27th February 2012, 09:47

It can make the noise when idling but only slightly and not consistently
But 2nd and 3rd at 2-3k RPM, definitely occurs
Should be able to listen when idling and neutral up to 3k RPM to check though

27th February 2012, 09:49

I'd do that in your shoes, best way to find out really. I do suspect some induction noise but there's no way to be sure. If I was in your car I would probably tell you what it is, unfortunately i don't have the magic powers of distant hearing

27th February 2012, 10:02

Shall attempt it
Induction noise is far deeper and less metallic than this noise
Damn you and your lack of powers!

Thanks for the help though

27th February 2012, 10:20

no worries. Like I said if I was sitting in your car I would probably immediately hear where it comes from. I'm sure you'll find out what it is soon enough...

Hope I can!

Thanks

27th February 2012, 11:22

Mate i think i havr the same problem?
Whilst in 2nd-3rd if i put my foot down when revs are low it makes like a cranking/metaly type noise?
Is this what your getting?

Yeah a metallic rattle
But does it with no throttle, lifting off at 3k and dropping to 2k

27th February 2012, 12:18

Mine makes this noise when putting my foot down to the floor in low revs in gears 3 an 4
Not a clue what it is tho :s

27th February 2012, 21:27

Louder on lift off for me!

27th February 2012, 21:35

exhaust pipe may be too close to bumper ... used to have same problem .. get under the car and where the exhaust is held by rubbers bend the small bar that is going thru the rubber until the exhaust has enough clearance

doubt it
but shall check it

thanks

This is a video
I'm holding the inlet manifold pipe and just moving it backwards and forwards
The creaking doesnt sound good
Anyone clarify?

Could be an engine mount needs replacing?

1st March 2012, 20:12

Does it do it when from cold? mine has a rattly noise when i tap the throttle/change gear and when the engine warms up it some what quietens down

Nothings loose at all.

It does it from cold
Constant sound - never quieter
Sounds like the sound in the video but sped up as obviously I can't shake the engine that fast!
Sounds at 2750 rpm and 2000-2200 rpm in 1st 2nd or 3rd gear

Just does my head in coz it sounds like the car is falling apart!

I say rattly, more of a squeak as i change gear the engine vibrates. But if sit and rev the engine to get the mounts moving no noise.. Once its warm the noise goes on mine.

its embarresing though. Il have a look @ your vid.

1st March 2012, 20:20

In the video there is a definite creaking
But when moving the sound is more rattly
If I had a steadier hand, the engine movement would be more visible!

1st March 2012, 20:21

Is the bolt the downpipe bolts to tight?

1st March 2012, 20:23

I shall give some exhaust bolts a tighten and tweak tomorrow and we will see if that's a problem
If not be mounts will be changed

1st March 2012, 20:25

How much are new mounts out of interest?

1st March 2012, 20:59

Standard ones?
Not a clue
I've got Baker BM group N ones to put in
But the noise does sound like a spring grinding, like on the down pipe!
Any ideas how tight that has to be?

Ah well they are more solid anyway iirc? so id just ignore the noise as the rattles will over power it. Lol.

Id just do it as tight as it would go. Im going to check mine over tommorow after work.

1st March 2012, 21:07

Ok nice one

Thanks

2nd March 2012, 11:48

Brand new video
Phone Is placed next to drivers front wheel
Noise is distinctly heard on the revs coming back down after being lifted
Metallic shaky/rattle sound

Definitely that sound
But where from!?!?

The downpipe bolts were tight enough

2nd March 2012, 11:49

Easier to access link

Thanks!

2nd March 2012, 15:52

Bump for diagnosis!
People saying baffles in centre section
Too loud for that?

2nd March 2012, 17:31

Think I've found it
And it's annoying at what it is!
The lower exhaust mount - on the down pipe is loo/none exist at
Problem is, I don't see where the bolt should go!?
There doesn't appear to be a thread for the bolt to go in
Images will show

3rd March 2012, 04:42

should bolt onto the gearbox. on the third pic it looks like there is a hole for a bolt slightly out of line with the manifold hole

Just pull the pipe down a little and it should line up

What bolt is it/would it be!?

4th March 2012, 23:11

Anyone know about this bolt!?

5th March 2012, 00:17

Exhaust rattle at all ?

yes it should line up.

can't honestly remember. think it could possibly be a torx or allen type. have a look in this guide it might be in there

Will have a look
Nice one thanks

5th March 2012, 21:47

item wasnt in that link
anyone any ideas what size bolt im looking for?

thanks

9th March 2012, 14:06

Can't for the life of me get those holes to line up
The manifold is just too rigid to allow movement down on the downpipe :/

9th March 2012, 14:50

i wouldcheckto see if you exhaust is hitting the ARB mine was
and then you couldcheckthe see ifyour induction pipe is hittin the brace because you will have engine tilt when throttle and lift off

I'm pretty sure it is the missing down pipe bolt
But I will check those too

9th March 2012, 17:47

Mine sounded similar for while and it was the heat shield on the cat under the car. Ripped it off and it went away. is your cat in the manifold though?

9th March 2012, 19:10

Cat is in the manifold
Oh and I'm sure that it's this missing bolt

10th March 2012, 08:04

Remember having this problem on my Ax GT's, happened all the time!

Can you not place something rubber in between the exhaust and box? Not sure how you could secure it mind but would stop metal on metal!

Thought that
But not a clue what to use!

15th March 2012, 18:40

try bending the bracket out the way just to make sure its def that mate, if it is ya need a bell housing bolt which has a 8mm allen key head on it, hope this helps

Wouldn't want to bend it out the way, would rather bolt it up!
Just need to slacken downpipe/cat bolts that attach it to manifold and it should drop a little/enough to attach!

15th March 2012, 19:57

You can just hear my squeak in this vid going fron 1st to second. No idea what it is though.

3 secs in .

yes thats it popping at the end.

15th March 2012, 20:28

That sounds like a gearbox squeak?
Either that or a hole in the exhaust whistle as back pressure goes back through it?

Nah gearbox goes through gears smooth and has no whine or nothing so cant be that. No holes in the exhaust.

Its like when the engine jerks to as you bring the clutch up but which mount?

Changing the spring that connects thw downpipe to cat this week to see if its that. Mine looks uber rusty so might be. If its not il have ot work around changing all the engine mounts.

15th March 2012, 20:38

as for your exhaust why dont you take apart the whole system, then rebuild from manifold back, that way you should get the bolt in on the mount. worth a try?

I've tried from the backbox forward
No avail
So thinking just dropping the cat a little bit to try make the bolt line up

I've got all mounts to change too!

Il start with the one next to the downpipe.

Had the car on the ramps the other day when i was changing the centre section and everything is solid under there. I have no grinds knocks when turning so it must be the mounts.

Im just going to put a powerflex rubber in mine. (i think?) and then price up new engine mounts next to the ecu and gbox one. Im pretty anal.

16th March 2012, 00:36

Im just a time waster :/
I've had my group n's since like January!

Dear meh lad. Tbf i changed my back drivers slider pin and clips and was meant to renew the pass the same time but i delayed it a week. Ive done it now. Next thing is the pin that goes on the gbox somewhere, little pin ive still got that to do. ive had it nearly 2 weeks. Doing that this weekend.

16th March 2012, 13:16

Think I'm actually just going to leave until I fit a 4-1 piper instead!

16th March 2012, 15:25

I put a jack under the gearbox mate just gave it enough tilt on the engine (similar to acceleration) to get the bolt through

Sounds a good idea actually!
Could push the gearbox in line better
If it messes the mount up, at least I've got a new group N to put in!

23rd March 2012, 09:26

Having another go at getting this bolt in today
Bump for fresh ideas
Not sure the 'push the gearbox up' method will work, coz surely it will just push the engine to too, thus moving the manifold and downpipe higher?
The downpipe is too high as it is!

23rd March 2012, 09:48

Which one are you changing? the one next to the downpipe?

23rd March 2012, 09:50

The one that bolts that downpipe to the gearbox
It currently isn't though - thus making the horrendous rattle
I need to put one in
But the downpipe sits too high against the hole in the gearbox

23rd March 2012, 09:59

This one? *old pic

Or

Ah that nut that bolts in...

Ordering a new rubber to go in mine. Almost positive its that. Nothing else rattles/squeaks.

Also how skinny is the downpipe LOL...

23rd March 2012, 10:06

That 'squarish' bracket, a bolt goes through there
Mine is missing

23rd March 2012, 13:28

2nd attempt
Still not luck :/
I can't pull the downpipe down enough to line up
Any ideas people?

23rd March 2012, 13:34

standard mani?

Im just bashing out ideas but how much of a gap do you have? post a pic.

My only suggestion and im not sure if it would do the mani stud threads any good is loosen the mani abit, just a little then bolt the downpipe in then nip up the mani.

Other then that i have no idea. Is the downpipe twisted somehow?

Well I've just driven with it
And there was no noise!

It probs got sick of you faffing with it so it let you off with the noise haha.

23rd March 2012, 15:36

In all honesty I did get tempted to just hacksaw the mount off

23rd March 2012, 22:11

Just found this it lists 2 different bolts though.http://www.catalogue.bosal.com/pages...sysnr=02414040

26th March 2012, 11:35

Doesn't seem to matter either way about the bolts, i cant even get the downpipe low enough

26th March 2012, 13:14

i have the same rattle and i dont have that mount at al; snapped off/
Check the radiator heatshield

30th March 2012, 20:34

Will do
But I don't have a radiator heatshield?

30th March 2012, 21:26

i think mines the baffles but not sure im going to search tommorow

will let you know my findings

31st March 2012, 22:56

Nice one

Thanks
