Quite an overlooked service item is the cambelt, I've heard of countless people who either forget or choose not to get the cambelt changed leaving it 2 years over schedule, so I'm curious to know if anyone has ever had one snap on them

Yes, Renault 5 many years ago.

Although in hindsight it may have been a timing chain.

A friend at College (~2018?) Had a cambelt snap on their Pug when they started - Lunched the head.

Yup, my first car back in the 90s.
“Remember, sort the cam belt soon” said the private seller.
“Will do!” said a teenage me..
Ended up beyond economical repair within 6 months and that was that.

No, but it's something I always take into consideration when buying a car (assuming it uses a belt). I hate not knowing when it was last done, and if there's nothing to prove when it was last changed I'll get it done myself ASAP.

Yep, first one was due at 74k service but snapped at 35k miles. Found out afterwards the service schedule had been changed the previous year to 30k. Then same car after £2k to repair the head a fan belt let go and shredded and managed to get between cam belt and pulleys so the timing slipped and another 16 bent valves and mileage still only at 50k.

Yes several,

Seat Leon tdi new belts water pump etc in 2007 at about 85k then went on until 2016 and it snapped on idle at 185k, my own fault completely. So 9 years and 100k out of a dayco belt. Bent two valves, rebuilt and went on to do 250k.

Honda Civic 1.6 vtec 7th gen? Tensioner failed because it wasn't replaced with the belt, took out valves etc, rebuilt under Honda warranty.

Passat 1.8t b5.5 not mine, new cambelt tensioners, water pump failure, the garage didn't replace it, car written off, 20 valves on that one.

yup while back. early mid ish ninties maybe

I had a cambelt change done at halfords in Chadwell heath. a few months later the belt snapped.

ended up with a few belt valves. Luckily it snapped in a crawl going past the circus taverl on the A13.


I persued Halfords and they paid for the repair, initially offered me the cost of the belt back. lol.

Once on a vectra and once on a corsa, both with only 30-35k miles and a couple of years on belts that had a 60 to 80k change interval. the ecotec was really when vauxhall went down the toilet IMO their engines were excellent up until then.
Had a camshaft itself snap on a citroen dispatch which caused the belt to fall off but remain intact

Some dodgy record keeping from a previous owner falsely said the cambelt had been done. Nope and it went on the A3 at about 70mph in a Lexus RX400H.

Waterpump went at the same time or was leaking which weakened the belt apparently.

Total damage = nothing.

New belt and pump and engine was perfectly fine - the cambelt was a shredded mess though

Twice.

First time on my Datsun Sunny, when I was poor, took ages to straighten the valves, six bent, with two of the exhaust valves having dog legs in them, but I managed to get them all straight enough to work.

Second time, 1.6 petrol Transit, with a low compression non interference engine. Rang the local factors, who we had an account with at the time, they delivered to the side of the road. Running again within two hours.

I've seen a couple which stripped the teeth off the belt, and one where the tensioner failed causing the belt to jump a couple of notches. I've never actually seen a belt snapped.
Is this unusual or do people just presume that the belt has snapped when told it has failed?

Fair comment.

My Datsun stripped a few teeth, then picked up again, which was why so many valves were bent.

The Transit belt snapped.

I had one snap on a 2.0 Cavalier, that engine then ended up in a Corsa with nothing more than a new belt, water pump and a service, good old non-interference engines!

I also had one snap on a 2.5 mk5 Transit whilst trying to start it one very cold morning , I ordered a new belt when it happened, straightened the push rods in a vice whilst waiting for it to be to be delivered and had it running again that afternoon, it actually ran better afterwards smile

A woman I work with had the belt go on her Audi TT 225 years ago. She cherished the car and it was within schedule when it went, surprisingly. The head and valves were damaged IIRC but it was fixed and went back on the road.

Nope and only changed one in my ownership of cars. I have mostly had sheds were the price to get it changed was worth nearly the same as the car.

Got it replaced in 2019 though for my Golf.
