vibrating noise by cambelt

[Monks Seat]

hi all,
the other day i noticed that i had a slight chattering coming from by the cambelt and also my idle rpm had dropped bu bout 25 rpm. so i took the cover off and i think it was coming from the cambelt guide tensioner, i took it to seat and they sed there was nothing wrong, well no when i rev the engine now to like 4500 to 5000 rpm i get this vibrating noise coing from by that tensioner, has any one got any ideas of what it is and what i can do???
any help would be great.
cheers

I guess it's the tensioner How long since the last cam belt change and what is the mileage? Tensioners etc. are replaced when the cam belt get done - should be every 4 years or every 60k miles.

the car is only 2 and a half years old, its dun 24000 miles, i really duno wt 2 do.

to be honest, i would take the tensioners off and have a look, ive got the chamshaft chain and all that off mine at the moment, waiting to reallign the timing on it

Maybe try another dealer or try and get a 2nd opinion from somewhere. If it is affecting idle revs and vibrating then it clearly is a problem and you don't want the tensioner to fail.

i agree with what kriso is saying, if the tensioner was to break, then this could probablys lead to further damage, and if the belt snaps then ... i think you can guess the rest lol

its really annoying me tho, is it hard to check? iv only ad the car a month, its been such a problem child so far! when i first had it i noticed a knocking, i took it to seat and to cut a long story short i ended up haviing a new power steering rack, power steering pump, new anti roll bars, drop links. but i still have the noise and seat av sed its the bump stops and every ibiza dus it! i duno if it true or its a load of bullshi$!!!!! any ideas?

not to sure about the 4cylinder engines mate as mines only a baby 3 potter, so on my engine you have to support it befor you even take the camshaft chain cover off! but on the 4cylinders i dont think you have to do that, i would get a haynes manual and read it up, even if the manual isnt the same car, just look for one that has the same engine

 

[Monks Seat]

iv had a quick feel and the guide tensioner feels solid, so im lost. any more ideas? or has any one else had anything like this???
cheers

maybes the vibration from the engine makes it vibrate when it is running? run your engine, get the longest screw driver you have, and put the metal end against the casing and put the plastic screwdriver hanel against your ear and have a listen and see if you can hear and others noises, the screwdriver trick works just like a stethoscope

il have a proper look again 2moz, but knowing the luck im having the cambelt will snap and the ibiza will b a gonner! lol

 

[Monks Seat]

im sooooo pi$$ed, iv had a real gud look and listen 2day and the tensioner is solid yet it still vibrates from that area. any one got any other ideas how to stop it? apart from changing it? also any more ideas on why im still getting the knocking from my front drivers side wheel, iv put further up in mi thread what has been replaced??
cheers

The first thing I'm going to ask is this:- Does the belt tensioner in question tension a toothed belt or a flat belt with no teeth? The cam belt is flat on one side and toothed on the other.

I'm thinking that you are getting your belts mixed up.

If we are deffo talking about a toothed belt, you are in grave danger of an engine failure. If we are talking about a flat belt then it's your alternator belt tensioner that is the problem and it isn't a big problem.

Alternator belt problems can cause variations on the tickover too as the alternator load affects the tickover speed.

Once we have established the tensioner in question I think you will find that you have a tensioner bearing failure causing the vibration/noise rather than a loose tensioner.

 

[rocky2008]

yeah, my car used to have a rattle on the alternator belt, but it sorted it self over time really

 

[Monks Seat]

Thanx 4 the replys, its the tensioner on the back of the cambelt, its only a little bearing, it ain't the altonator belt, I'm at a proper loss with this one, I duno wt 2 do cus I no its this but seat won't do any thing, when I took it 2 them I no they didn't listen to it properly cus I watched wt they did, when I told the girl on the desk they were like we have looked at it! I was like such a liar! I no its my luck it will all **** up!

 

[rocky2008]

if thats the cae then i suggest you replace it befor you regret it

go to a different dealer, or phone customer services and tell them they will sort it for you
