Hi, well thats the strangest title Ive ever given a thread!

Im helping a mate out with her ST200 2003.

It has a VERY loud noise from under the bonnet.

I thought it was the power steering pump, but its too load for that, I hope!

Its so loud you can hear it from quite a distance away, like a fog horn!

Could she be experiencing moosing?!!!!!

Thanks

Mark

If it’s a 2003 car it will be an ST220, not an ST200.

 

Im sure there are loads of vids on youtube showing moosing, the one below is the first one I saw on a ‘ST220 moosing’ search :)

Hi yes its a 220!

Great thanks for the links.

The only one I found before wasn't so loud!

I think that's the issue, Ill apply the remedies suggested.

Cant wait to tell her that car is moosing!

Thanks!

The IACV, or it’s gasket is normally to blame.

My 2.5 v6 moosing sounded like this, after second cleaning of icv valve,

replaced it with new iacv valve.

It doesn't really break, not at first anyway, I think it just becomes so crapped up with dirt over the years it stops being able to open/close fully. So it still works to a degree, but when the airflow increases the valve starts bobbing up and down and letting air through when it shouldn't. And due to the design of the system, it makes that signature noise... like someone farting down a hose pipe in rapid short bursts.

 

That does look like the gasket for it, but honestly I wouldn't have thought you could fix the farting moose by replacing that alone. I suppose if the gasket was severely corroded and letting air through it then it may make a noise but I expect it'd sound more like a vacuum leak, added to which you'd likely get rough idle if not stalling issues.

 

Cleaning it can work but it depends how far gone it is. I tried cleaning mine but it only stopped it moosing for about five minutes before it started doing it again. But, mine had been moosing for years - I just ignored it until it finally got worse and started to really annoy me. Maybe if I'd cleaned it when it first started to moose I may have got a few more years out of it.

 

I've also seen people recommend the "anti moose pipe" which replaces a vacuum line with something longer and thicker - all that does is mask the sound being made in the pipe, it doesn't actually fix the problem. Ultimately, I think the only real fix is to just bite the bullet and replace the valve with a new one. I got one off ebay for 40 quid and it came with a gasket too and my car hasn't farted since.

 

Edit: Although it has developed a severe drinking problem but that's likely unrelated to the IACV.

I’d better add a bit about the gasket.

The issue with the gasket can be when people clean the IACV, or remove it to paint it etc, but re use the old gasket.

The moosing can continue until a new gasket is fitted.
