Maybe I'm wrong then but it just seems illogical to me that the gasket can cause the noise at all because if the gasket was leaking that bad the air would be being sucked in through it and you'd probably hear a noise but it would surly be more like a vacuum leak as I said before, because the air entering the engine isn't passing through the actual valve and it's already established that the valve malfunctioning is what causes the noise.

 

I think a more likely explanation is whoever claimed the new gasket cured their moosing problem has cleaned their IACV once which didn't cure the problem, put it back on with the old gasket and found it still moosed, so took it off again, cleaned it a second time which did cure the problem but also replaced the gasket with a new one and when they found the moosing was gone, they assumed it was because of the new gasket and not because a second clean actually did the trick.

You may have not got what I typed

The IACV can be removed purely for painting or as part of a larger refurb. Re using the gasket can lead to moosing, which is then cured by fitting a new gasket.

The same applies for cleaning the IACV, it’s best to fit a new gasket.

 

When I refurbed my IACV the car was noisy until I fitted a new gasket........The refurb didn’t touch the inside, it was purely cosmetic.

I do get what you're saying. You say it was noisy, you replaced the gasket, the noise stopped. I'm just saying I don't see how the gasket alone cured your noise since the "woo woo woo woo" or a prolonged "wooooooo" noise at idle if it's really bad is the actual valve failing or failed. Then again I'm only speaking from experience of the Duratec 25, the ST220 obviously has a different air intake and inlet manifold design so manybe that has something to do with it

 

Fun fact as if it wasn't actually obvious from the nickname, but the noise is of course called moosing because it actually sounds like a bit like rutting moose:

Only the Duratec has a deeper voice apparently. Anyway not to worry I'm sure if the OP wants to try replacing the gasket first it'd be considerably cheaper than the valve so wouldn't hurt to try first.

No, I wasn’t saying that

Im saying it wasn’t noisy. I removed and refitted the IACV as part of a refurb, but used the same gasket. It was then noisy. I fitted a new gasket and it was back to normal.

 

For various reasons lots of people remove the IACV and then suffer moosing.

This can be purely as part of a spruce up, to tart up or polish the UIM or to remove the UIM in order to change the plugs.

My old 2001 2.5 used to suffer from moosing, the warbling kind and the funny looks I got from people was amusing ha ha.

I never bothered replacing any parts and just used to pull the iacv and blast it with carb cleaner and it would behave for a few months before needing it again.

My current 2002 2.5 has never done it, don't know if it will as the miles increase but its still only on 73,200 so fingers crossed it will behave for a bit more

Thanks for all the advice!

Ive got a new ICV, fitting it this weekend, should sort it!

Ill make sure the gasket is ok or just make a new one.

The cars got all kinds of other issues, like probably running on 4 cylinders, very loose front suspension etc etc!

So I may be back for more help!

Quick update

New ICV fitted , the Moose has left the building!

Very happy owner, she had been told all sorts of things like, "they all do it", "Its because its cold" etc!

Thanks for the help!
