Help! Strangest Sound From Inside The Dash

[omri617 18]

Hi again dear friends
Suddenly there is this sound :

Things done before it came :
replacing the radiator .

It sounds strange , like coming from the dashboard inside , where the passenger foot area and the glovebox (my car is left hand drive)

I changed the right (Long) driveshaft , it didn't make any difference!

Dunno why but it wont share direct from youtube either. Could be a worn bearing shell maybe big end does it run/idle ok?

Get underneath, there is a heat shield that clips onto the steering rack.

 

My OBD car had this rattle on over run and this was the cause. It was unclipped causing the rattle.

[Slo 283 1 Cars]

Sounds more like an ignition fault like its running on 3 or missing etc does it drive ok or does it hesitate/struggle to go does it idle?

[omri617 18]

it drives fine , no change in the power of the car

 

i will check the shield right now!

[omri617 18]

ORB - got underneath the car , couldn't find what you told me

I never saw there is a shield for the steering rack

 

By the way , it increases when pushing the throttle , and also when the car is not straight , entering my parking lot some uphill and a turn.

I must be deaf cos i cant hear bugger all wrong there, if the cars running fine and theres noise coming from the footwell/behind the dash area check your manifold for cracks as mine ticked quite loudly until i welded it up

 

Oh and put some fuel in before you run out

[omri617 18]

On the second video , listen to 1:30 onwards..

[Dizzee stuff 33 1 Cars]

exhaust blow, cracked manifold or manifold gasket ????

Downpipe hitting linkage?

[omri617 18]

why the sound increases when car is on uphill a bit? why it increases when throttling?

[omri617 18]

Question :

 

When car is stall , running in Neutral , pushing the throttle increases the noise . which parts are moving in there that have potential to be the cause?

[Slo 283 1 Cars]

Alternator, waterpump, power steering pump (if fitted), bottom crank pulley could be loose and potentially anything inside the engine

 

could also be something moving around hitting the alternator fins

Will check all you mentioned 1 by 1 tomorrow.

Thanks Andy

sounds like a blow

Downpipe hitting linkage?

 

I'm with ORB on this. If the sound I'm hearing is what you are questioning, it's most clear in the first video and sounds like a very dull and hollow rattle, that comes in when you blip the throttle and then hold the revs. So to me it sounds exactly as I'd expect from the downpipe touching something, such as the gear linkage, subframe or exhaust tunnel.

 

It's most likely that your engine mounts are knackered, and so the excessive engine movement when revved is allowing the downpipe to come in to contact.

 

Edit: listen to it from here http://www.youtube.com/watch?feature=player_detailpage&v=x01RhnkAwQo#t=24s

+1 on the worn engine mounts. My aftermarket 4-branch was knocking massively against the long gear rod until the engine mounts were upgraded, hasn't done it since!

[omri617 18]

How many engine mounts there are and what are there positions ?

[GLPoomobile 958]

You know you could actually work that out for yourself if you spend 5 minutes peering under the bonnet.

 

You are going to have to start helping yourself if you want to learn anything about these cars.

[omri617 18]

yeah you are right actually , i wrote this when i was under the car and using my phone as light , and as a guide

got under the car and checked the things mentioned by the answers of the great members here . Step by Step .

Eventually , to find out that the engine mount is Cracked!

So you were right Barnaby about it all I thank you , also to you Lemmingzappa

here is how it looked -

 

Thank you all again.

[GLPoomobile 958]

Good. Hopefully you didn't take my last post as offensive. I was using my phone and can't use emoticons to soften my tone

 

Getting quick answers from the forum community is great at times, but don't let it become a dependancy. The best way to learn is to be hands on and try to figure things through yourself.

[omri617 18]

Not at all , even if it was a bit tiny offensive , Sharing your knowledge , help , and the will to answer silly questions all the time from us , just makes it vanish. ​
