RATTLE SOUND FROM TOP END OF CLIO 182 ?

[neilsafc]

Anyone got any ideas what this rattle sound is on my clio 182. It seems to run ok but noise is on from cold and gets worse when warmed up hot ?. link to video below.

Dephaser maybe ?

expensive only had car since april got a warrenty on it would it be covered

Have you had the inlet off and checked all your spark plugs are done up tight? Just a thought but it could be worth a try before anything else

 

[neilsafc]

no i havent would it not miss if they where loose other than the rattle the car funs ok

That doesn't sound like dephaser to me, sounds like something is loose.

No it wouldn't as it's still in the bore and connected but they are know to work themselves loose, especially in cylinder 3. Mine did even though they were all torqued up correctly, had a feeling what it could be so had it all off and voila, a nice loose spark plug that had backed off a turn and a half or so :/ mine was running fine but just started to sound really noisyand tappety.

Seriously worth a look, it'll only take half hour tops to have it off and back on again and could save you a hell of alot of work and money. Even if it's not that you might find the issue when you've removed all the top end clutter

 

[neilsafc]

Well I've had top of spark plugs fine not loose, rattle sounds like its coming all the way along the top through the cams

I had the exact noise it sounded loose and around the camshaft area,it turned out to be the waterpump bearing had gone!!

Been to a garage I was told to go as one of the guys used to work for renault straight away before I even popped bonnet said dephaser knackered and I don't think the warranty covers it well sick as only had the car 2 months last Renault I'm buying me thinks

 

[Cookson]

Should be covered under warranty tbh

 

[Jonff]

That really doesn't sound "dephaserish" I know it sounds daft but is the engine cover on tight? Also check the fuel rail guard.

 

[neilsafc]

Thought it would have but it wasn't bought from a main dealer and warranty is through warranties 2000 and it the gold warranty if anyone knows this warranty company

 

[Lloydy]

erm... if theres any power loose and not revving like it should when going for abit it could be the vvt pulley, maybe?

if so then looking at £125 for the pulley and recommended cam belt change which are about £450

 

[MartinR]

Here's a video of my waterpump (off the car) but you get the idea on how noisey it would have been at idle speeds etc.. it never leaked either?

 

[neilsafc]

There is power there and revs normal just makes a right racket like in my video above in link

 

[neilsafc]

Would you get the same symptoms with a water pump then as you would a dephaser meaning when you but ears near the top cover sounds like cams rattling

 

[MartinR]

The specialists that looked at mine first said it was the dephaser then put it down to a failed rocker! so took it to my usual place and they found it to be the waterpump. And it sounded like it was coming from the rocker cover/camshaft area.

 

[mark123]

One of the idlers on cam or aux belts failing?

 

[neilsafc]

Hmmm so many things could be then

 

[Cookson]

Well, if you get the cambelt, dephaser done, and get the water pump done while its all off, you should be sorted

 

[Scutch]

You'd know if it was the dephaser. There's a few vids on Youtube of that failing. Not a nice sound.
