Ford Ecoboost 1.0 Cambelt Changes starting to be due @ £1000+

Cheat? It’s literally the test which measures emissions. There’s no cheating

whos Boris ? Is he the guy who you googled ?

I assume its because when emissions testing, it used to be ram at a constanstish speed. Wouldn't surprised me if some of the turbo were tuned to not produce boost at that point. Just have to look at vw to see that the tests can be rigged (obviously a different test), but shows it can be done.

Boris the PM who is driving the EV revolution and contributing to the price of petrol and road tax that I pay, with supposedly co2>200g/m
which means my NA petrol is expensive to run
- wasn't that obscure was it

e: so ecoboost's ( 1.0 .... ) have gone back to chains on newer generations ?

Was going to post the same thing myself. Had a 2014 Golf 1.4 TSI which was sold with a lifetime belt but that then got adjusted to a normal belt service schedule. Pretty sure this spread to all the VAG sub brands using the same engine.

However, wasn't as painful as ford turning around and asking for £1k, think we paid an independant a couple of hundred quid.

This thread worried me for a bit as my 2016 Focus ST is going be 6 years old this August

But after looking at youtube my engine has a timing chain and not a belt :)

Doesn't the Focus and my C30 have the same underpinning P1 platform? I changed the timing belt a couple of years ago and it was about £400 I recall, and that included a new water pump too since it's right next to it.

yes it’s very obscure to be honest. We aren’t in your head and don’t know what you are thinking. Not sure how EV has come into this ?
There is no impact of EV on fuel or VED Nothing has changed in several years

They have, I think they came in around 2019 with the revised engines, the ones with cylinder deactivation and revised turbo and manifold. It is possible they went chain + cylinder deactivation for greater co2/fuel savings, however I've heard cylinder deactivation has been dropped on even newer engines, but can't be sure on that.

You’d want a turbo to creat boost. The fact it uses some energy otherwise wasted to reduce pumping losses (in combination with low friction 3cylinder engines) is why downsizing was the tactic for the NEDC test and a real solution to lower CO2 whilst meeting emissions

VW situation was different as -it is alleged - they admitted they programmed in that the car detected it was on a test so increased EGR intentionally hence lowering NOx

Ok so that really is an admission that previous design strategy was a dead-end, I wonder how they explain the u turn, and,
whether other manufacturers still in ICE are doing the same.

people with failures should be able to use that to help in any class-action (against the false claims by belt manufacturers)

How on Earth is that an admission. Timing chain technology moved on in 10yrs.


Class action? You buy a car with a warranty for 3-7 years. After 10 you have nothing to fall back on.

I have no actual evidence or idea myself, but from some of the Ford forums I read, someone posted this

newer 1.0 ecoboost has timing chain instead of the belt due to the cylinder deactivation technology implemented on the latest ecoboost, with this feature, modification have been made to the crank shaft and the timing belt is replaced with a chain to support the increased mechanical load when activating and deactivating a cylinder

Not sure if true.

I have a Mk8 with a chain and my parents have a Mk8 with a wet belt, the wet belt is definitely smoother and quieter, you can certainly feel the difference. I imagine the goal for these manufacturers is to get the cars certified at the lowest CO2 output with the highest fuel economy weighed up against design etc.

Presumably when emissions standards change, and fuel economy testing changes, different methods become more or less viable. It could be cylinder deactivation was their preferred method now, but it might have required a chain to accomplish?

Now they've gone mild hybrid they've been able to make the turbo bigger/different and generate less boost and lean on the hybrid stuff a bit more.

The cylinder deactivation makes them feel rougher as well, maybe something that can be disabled in Forscan. I know Mountune turn it off on their remaps for the 1.5 ST.

Yeah I find it is noticeable. I think popping into Sport mode disables it also, but again I could be wrong, it feels as though it does disable it when I try it.

I think it the older mk2 focus which has the same platform as the Volvo C30

I have no idea what platorm changes there are between the Mk2 Focus and my MK3.5 Focus
 
Not sure they share anything these days. Ford doesn't own Volvo anymore. It was only the mk2 afaik and I don't think they used the same engines except for the ST, which had the T5.
 
What's so complicated about these new fangled wet belt changes? Presumably it's a toothed belt which sits on the cam and crankshaft pulleys, with a tensioner I imagine, and somehow has an oil bath too. I imagine lots of ancillaries might need to come off to get at it, but what is this special tooling that's required? Does the belt sit in the engine, rather that sitting outside the engine under plastic covers?

It requires a lot more components to be removed. Whereas timing belts are generally just behind a plastic cover and an engine mounting. A wet belt has to be sealed in the engine like a timing chain, so the entire front cover is usually aluminium which usually also involves removing the sump. Theres also the fact that the alternator and water pump are bolted to or through the front cover. It's a very labour intensive job. There's also time involved cleaning up sealant and resealing the front cover and sump.

In the Fiesta there's not a lot of room and some people even prefer to remove the engine entirely to do the job.

Yes unfortunately

A torque multiplier is required to remove the crankshaft bolt as well as special locking tools I believe
