Hi guys

Can anyone here confirm if my 1.4 TSi Yeti (due next month) will have a chain driven camshaft?

Many thanks. Andy :-)

I know hes not flavour of the month on here

Petrols are chain, diesels belt.

Thanks gentlemen - I'm very happy with that :-)

I always favoured the idea of a chain but I have heard of many that stretch, rattle and snap (not necessarily Yeti but other VAG engines). Chains suffer from modern long life servicing due to the quality of lubrication. VAG belts, on the other hand, are generally quiet and trouble free. A belt would not put me off.

What's wrong with Honestjohns flavour ?

His original video road test of the 1.8 TSI Yeti was very favourable.

I had a chain on my old Honda CX500. That needed replacing at regular intervals.

Chains are not the magic solution to all maintenance requirements. I'd imagine they are more likely to go since the majority of people think they require no attention. They still need adjusting and checking and what about ancillaries on them like water pumps?

In my experience chains don't require any attention and have automatic adjustment and I have not known any to drive water pumps. I may be wrong of course. The first sign of wear is usually a rattle on first start up, and later, a rattle on tickover.

Some of us are old enough to remember A Series BL engines and timing chain rattle!! They ssttrreecchheedd but still worked!

Personally, I like his column in The Telegraph, but I have noticed a few adverse comments around here

Rock hopper ...a CX500?......good grief, that's going back a bit. The despatch rider's favourite and I remember thy needed a mod to the timing gear. I always felt they looked like a generator on wheels to be honest - I had a Suzuki GS1000S at the time I think - happy days :-)

And the memories come flooding back

In those days I rode a Yamaha Xj650 then an XS1100. Oddly nearly every Honda I owned had cam chain gremlins. Both CBR600s (89 and 91) seemed to eat them, seems that back then the tensioner was the cause of cam chain problems. All my Suzukis, Yamahas and Kawasakis over the years seemed OK (apart from the Kwaks where the paint fell off)

Motorcycle thread time - get pushrods, they are fine on my BSA's, but the Guzzi has chains.

Maybe gear cams - straight cut or angled ?

The cam chain tensioners are always at fault, and when belts snap (see Renault), there is no warning first.

I like his column too, it has plenty of sound legal advice but his car recommendations are inconsistent and at times truly bizarre. He seems to write glowing road test reports of new VW's and then tell people to avoid them in his advice column. I've lost count of the times people have written in with a positive report of their ten year old VW which they are looking to replace with another and he replies with his default setting of 'buy a Ford or a Honda Jazz'.

Cam chains are normal in bike engines, although it is the cam chain tensioners that tend to get the bad press.

Bevel gear drive FTW!

Interestingly the newest (not yet Yeti) 1.4 TSi is belt cam though. I recall reading somewhere that VAG's experience with chain cams has been mixed versus say Mercedes. Although these days the smaller Mercedes petrols are Renault based units...

The latest VAG belts are referred to as 'lifetime' belts because they have a minimum life expectancy of about 200,000 miles without a specific time limit (if I remember rightly). I would be happier with that than a chain.

Is there a slight fuel efficiency gain in a belt versus as chain?

There should be. No chordal rise on a belt.

A series engines had duplex chains, as did Guzzis, apart from the very early ones which had helical gears. There were several aftermarket straight cut gear sets, usually in some aluminium alloy, NFG in my experience.

HonestJohn is a saleman, he doesn't appear to have any technical knowledge. He gives a big list of potential problems as reasons not to buy certain vehicles then ignores the same list when advising on what to buy, Jazz or Cee'd. But then, most Telegraph readers only do 2000 miles a year in 3 mile increments.

None of my old Mini or Moggy 1000 engines had duplex chains (with the exception of my Cooper S)

I used to do 40000 miles a year and still found time to read the saturday Telegraph.

I think you mean the Daily Express. That's what my 90 year old Dad reads,only He doesn't do as much as 2000 miles a year now.

Thanks Nick I had that impression but what is chordal rise?

Think the Honest John negativity is that he tends to have a downer on any car with problems as if it's the end of the world. All cars have common faults

You have to take everything you read on any forum with a pinch of salt!
