Hello,

Does the Octavia II have a cambelt and if it snaps, will engine damage result?

Regards,

Richard.

Yes and yes.

HTH

Why do you ask, most modern engines have a cambelt! :confused: Edit: just had another thought, which engine variant are you refering to?

Something I owned recently had a chain. I can't remember if it was my Primera GT or my Octy vRS Mk1. Probably the Nissan.

I believe most Nissans are chain driven, so it will have been that one

Our Nissan 2dlx has a belt, but my older Jags mk2 and 4.2 E type serious 3s all had chains, and yes its stops you in your tracks.

Octy 2, 1.9 TDI PD Ambiente 4x4 Combi and Nissan Sunny 2.0 DLX, Company Octy 1.9 TDI Tor Combi.

BMW are all chain driven too as is the yaris.

The cambelt saves the manufacturer some money.

If the cambelt snaps on any modern VAG engine, AFAIK they are all interference designs so it will trash the engine.

Yes and yes.

Well, my questions have been answered now, but I ask because as someone else pointed out, some engines have chains rather than belts. I ask about the engine trashing because some engines are non-interference and there is no damage if a belt snaps (e.g. my Mazda!).

If you have a TFSI motor there's no need to fear.It's chain-driven.They haven't been known to fail.

yep don't fanny about not having replaced, make sure the tension kit, new bolts and for what it costs a new water pump are fitted with the metal impeller.

The 2.0 FSi turbo is cambelt driven.

The 1.4 TSi is chain but not available on the Octavia II as far as I know.

Both have

I'm looking to get an Octavia 4x4, if it's been serviced "by the book", how reliable is the timing belt? Are failures a matter of chance, or are they normally brought on by poor servicing, i.e. no belt change?

As long as its serviced as it should (new belt every 80k assuming its a diesel) then failures these days are rare.

Why use interference engines at all then? I've done some reading and I gather that they might be more efficient and that diesels are virtually always interference? Why is this?

Diesels are allways interferance due to high compressions, this means effectively the piston has to get closer to the valves when the engine is running.

Sometimes the design of the engine means that is cant be anything else. Five valves per cylinder for example, just the angles they are at to get them all in means they will hit each other if not timed correctly.

1.8TFSI (TSI) is chain driven AFAIK
