Madness cambelt failure

today going through a tunnel my cambelt went pop thank god i took out warrenty cover in case of that eventuality so the car is at the garage looking sorry for itself and in the meantime i've got to drive round in the wife's calibra. bloody waranty co. have already tried to lay blame on the variater saying that as the variater isn't covered if that is found to be the cause of failure then they won't pay a penny, and the garage haven't had a chance to look at the car yet why do i smell a rat?? any how i can relive the moment as a warning for others ;
driving down through tunnel injector light comes on and the engine dies didn't even notice the engine had cut out,
so if ure bella's knicker elastic has'nt been changed and shes done over 36000 miles since the last change save yourselves a trip in the back of a breakdown van and get it sorted.

Re: cambelt failure

.....sorry to hear about your problem and I hope you get back on he road before too long with little damage to your wallet.

BTW you didnt say how many miles you had done and is it 5 years old as suggested by the 1999 year of your car or has it been replaced before?

Best of luck with the warranty, you pay for the protection, so I hope you get it sorted.

Re: cambelt failure

Bad news indeed...what was the mileage since the last change?

btw.....the variator will have NOTHING to do with the failure, but the tensioner might.

Re: cambelt failure

Wrinx is right. The tensioner is the likely culprit ... the older ones had a habit is seizing. You can soon see if there isa section of belt sans teeth. Or the belt may have just failed.

So if the warranty company want to blame the cariator, let them. I don't think you can tell if it is knackered or not unless it's on a running car.

Re: cambelt failure

I hate it when warrantee companies and general other insurance companies ie for furniture try to get of claims when you paid good money to cover for potential loss or damage

I hope they fork out, good luck

Re: cambelt failure

Bad luck

I had my variator replaced under warranty recently as it was rattling, so I'm surprised they are saying it's not covered. However, as others have said, I don't see how the variator could be at fault. Give them some grief if they argue the toss.

While the belts are being replaced (hopefully undr warranty) I would fork out for the variator yourself (around 100). Mine started rattling at around 40K and you wouldn't want to have to have the belts off again.......

Hope it works out OK.

Re: cambelt failure

scuse the random question, but whats a variator?

sounds more like a belt failure than tensioner, as you would possibly have heard the tensioner rattling before it comletely failed. i almost lost a 1.4 engine a few months back, but stopped as soon as i heard it happen luckily.

Re: cambelt failure

Welcome Buzz......the tensioner doesn't give much (if any!) warning and will just chuck the belt. Belt failures (from what I've read here) are very rare...check out Alfajacks thread about his 156 belt.

The variator is on the end of the inlet cam, adjusts the timing to give extra power about 3500revs (ish!). Like the VVT systems.

Re: cambelt failure

thanks for the support, guys car is being looked at today in hindsight all i could offer is that for the past month or so the car has started to have a top end that was getting noisier and noisier, car had done 58'000m but because the manufacturer still insist on 72k being the belt change time there shouldn't be a problem with the warranty co. coughing up, as for the variater, after the cars laast service my local independant put a claim in for the variater which the warranty co. said wasn't covered, so as it had only just started to go i was going to get it done with the belt service, guess that 's going to be sooner rather than later, as for the garage am in constant touch with them and the work will be guaranteed for two years.
any one else had a rebuild after cambelt failure, did the car run better after ??

Or every 5 years if you do less than 12,000 miles a year.

Re: cambelt failure

Sorry to hear about that, mate. Hope you manage to get it sorted with the warranty company.

Agree with Kurz - these companies are happy enough to take you money year on year, but will fight tooth and nail NOT to pay out when you have a legitimate claim on their policy.

The only one I know about was fine for about a year .... that had the top-end rebuilt. No damage to pistons. But two broken valve guides and new set of valves. Tensioner seized and stripped belt section. No strang enoises before it happened. Engine was being started at time, so damage was limited. Tensioner literally fell apart when it was removed from the engine. That was at 73K!!! Guess who was waiting for their local dealer to get a space for the service ... and well out of warranty.

After about 8K miles/one year though, a big-end went. Apparently the "shock" of the valves hitting the piston could have been the cause. This may have meant the bearing scored on the crank. Can't really say as it could have been a number if factors, but it was odd this happened so soon after. Anyway long shot was a bottom end rebuild as well - crank regrind, bearings, new oil pump and rings. When they had the engine out, there were two fine scratches on two cylinders and cracked rings. Polished out scratches so no rebore required. That engine now sounds much sweeter and the oil consumption is now about 1 litre per 10k miles ....

Just under 3K for both (at specialist) .... including two sets of belts!!

The chap I bought my QV off said that when he had the engine rebuilt it came back much better. He wasn't just telling me that so that I'd be more likely to buy it, when I offered him the asking price he said he didn't want to sell it any more!

So you get a noticeable loss of power when the variator is on the way out? I thought you could tell if a variator was gone or on the way out is if it sounds diesely for longer than usual on start up (mine sounds a little diesly for about 2 secs) Which i'm sure i read somewhere is the norm.

Mine too. I didn't know a knackered variator resulted in lack of power.

Only if it has completely seized in one position of the other.
i.e stopped variating.

Re: cambelt failure

Nakkered variator will result in you losing that extra surge in the higher revs band....you'll still get there, but not in the same way

Doesn't do any harm except to your reputation as the owner of a Twinspark diesel

Re: cambelt failure

I had a tensioner failure at 8000 km on my 2.0 TS, while I was doing only 10 km ph in a traffic jam, the engine was completely knackered, all valves bent pistons damaged, complete engine rebuild. Including new pistons. Tensioner (plastic Canadian made) was completely exploded. Luckily the car was on warranty, would have cost me a fortune if not. When does Alfa re-introduce a chain driven distribution like in the old days .... BMW (excuse me) with the new 3 series is back to chains... those Krauts know better !!!

Re: cambelt failure

since we are talking varaitors, i got mine changes 10 months ago under warranty as i was getting the diesely sound for a couple of seconds on startup. I was well happy because this included a cambelt and tensioner change for free at just under 3 years old. Just recently i noticed the sound coming back so i recorded the noise on my phone and played it at the dealer, and thankfully i have just had everything changed free of charge again.

Now i can certainly confirm it effects performance- i was shocked when i got the car back last week, it has loads more torque at low revs, so much more responsive and has a real surge of power now all the way to 7000 rpm. Also ive noticed it is running a couple of mpg improvement as well, a very happy person indeed. What im gonna do to help preserve the variator is to get the oil changed every 6 months

Re: cambelt failure

Preserving the variator is best done by keeping the oil topped at all times......running low will apparantly kill them.

Re: cambelt failure

yea i know, the thing is im so paranoid of not overfilling i usually manage to get the level just under max, but noticed after my recent service the level was a couple of mm above max and to be honest seems to run better at that level???

Re: cambelt failure

Just to let you know we heard a rattling noise getting increasingly louder so took our 147 to the dealers and they found that the cambelt tensioners were below the tension mark therefore needed replacing at 27'000 miles and 12 weeks out of warrenty!! After lots of wrangling Alfa UK paid the full cost but with no help from the dealership.

Re: cambelt failure

update on my car: nows seems after a week that the garage that i took my car to doesn't have the technical expertise to diagnose the fault for the warrenty co. who are trying every trick they know to pass the blame back onto me ; someone must have told them i am a serial cambelt snapper, only good thing is that they are reffering the car to a local alfa specialist who happened to be the garage who serviced the car last month and were willing to undertake warranty work on the car for minor issues at the time
