Dear all,
I had the cambelt changed on my v6 spider when I bought it and I soon noticed that there was a lot of whining going on.
Couple of weeks ago I got all the auxiliary belt tensioners and belt changed but the whine is still there - definitely from cambelt area.
I've asked the garage that changed it what they think (respected Alfa specialists in Oxford) and they looked blankly at me as if I was making things up - they insisted it's fine.

Went to another specialists in Oxford who had a v6 GTV and the difference in sound was enormous - mine was SO whiney in comparison. The chap who runs the place said that perhaps the belt was just a bit tight and that I shouldn't worry too much.
Are there any mechanics on the forum who know about these things? Can the tension on the belt be adjusted slightly? Anybody know anywhere that might be able to do the work for me? The garage that changed the belt don't think there's a problem and the other garage said that he'd prefer not to touch the v6!!!

What should I do???

Help please!

The whine is not correct, as it sounds like a failed or badly fitted tensioner. The garage that fitted the belt, was it Solo Italia or Palmer Phillips by any chance.

I fitted a cambelt a bit tight to one of my cars and it whined. I looked around a few forums and they suggested that waiting about 1000 miles would be enough time for it to loosen up a little.
The whine went away but if it hadn't within 1000 miles I would have gone back in and loosened it. That was about 40,000 miles ago and no failures yet.

It sounds like you are overdue the next change then. Should be every 36,000 miles ;)

Xavster, was the waterpump changed when the belt was done?

Yes it was one of those garages you mentioned that fitted the belt!

Nope - it was OK at the time..... Is that run off the cambelt? Do you think that might be whining or is it just precautionary thing?

How much labour would I have to pay to get the belt retensioned, or at least checked?

Thanks for the help so far!

My Spider Has Done This Aswell Since Cambelt Was Changed, Biit's More Of A Screeching Sound On Start Up Thou When Cold, People Have Sugested It's A Bit Too Tight, I Don't Think It Will Do Any Damage (hopefully) Just Sounds Bit Dodgy. Chap Who Did My Cambelt Says To Go Back When I Get The Chance And He'll Check It.

Screeching will be your Aux Belt slipping a tiny bit when cold so as you say not serious.

Hi,
If you have whine get it fixed as I'm sure that on the morning my belt went bang, water pump failure, I am sure I heard a brief whine when I started up. I know that two plus two don't always make four BUT are you up for the consequences?
No - exactly.
Whining is caused by over working bearings in tensioners and jockey rollers. This will cause them to fail. My wife knows this to her cost on her Corsa.
Good luck

I appreciate what you are saying and agree that a faulty tensioner can whine but there is something about the sonic qualities of toothed belts like cambelts that makes them whine when a little bit tight.

Aux belts are run a lot tighter but they don't whine.

I know how tight mine was because I only used hand pressure to push the tensioner while I locked it down, not a tool or lever but it still whined.

I have just had the cambelt, waterpump, tensioners etc done on my 156 (first week of ownership 64k on original cambelt) and the car now whines where it didn't before. I spoke to the garage and they said give it a few days and if it doesn't go away they will have a look but this is normal.

I guess all we can do is wait and see!!!

I've done a few v6 belts recently and have come across this problem myself, about 12 months ago:

Someone tried to change the belt on a freinds 156 V6. They ballsed it up and valves were bent. I rebuilt the engine for my friend but when I started it up there was a slight whining noise.

I couldn't identify where it was coming from and decided to see if the engine would 'bed in'......

It didn't. The whining became more prominent. It turned out it was one of the (new) idler pullies that was making the noise. The bearings inside were noisey.

The parts used were genuine Alfa but it may be that the idler was just faulty.

But I think its more likely that between myself and the initial culprit we damaged the new idler whilst fitting it. The bolt holding it in place was rounded off when it was first fitted. In order to remove it when I took the heads off, I had to smash a socket over the head of the bolt with a lump hammer. I think the percusive persuation may have damaged the bearing.

Replacement involved removing the cam belt again...
