MCF Posted August 30 Share Posted August 30 Out of interest is anybody aware of major engine fails with the 2017 onwards 1.1 engine or is that a 1.0 pure Ecoboost issue ? 1 Quote Link to comment Share on other sites More sharing options...
Eric Bloodaxe Posted August 30 Share Posted August 30 In theory it (and the earlier 1.0 version used in the Mk 7.5) should be just as liable to failures linked to degredation of the wet belt, if services are missed and/or incorrect grade of oil used, as is the ecoboost, (though not being turbocharged may reduce stress on the belt?). I can't recall seeing a failure mentioned on here, though there seem to be relatively few about, compared to the 1.0 ecoboost. I've never managed to find a sales figure for the non turbo version, while the 1.0 ecoboost had, I think, sold at least 1.6 million by 2019. 3 Quote Link to comment Share on other sites More sharing options...
Kolmo74 Posted August 31 Share Posted August 31 Hey! For a minute I thought I was the only person in the planet with a 1.1. 😅 I'm interested in this question too, obviously. Not too long ago, when I discovered the wet belt issues on the Ecoboost I got horrified of knowing the 1.1 uses the same wet belt. Well, maybe just worried... REALLY worried though! Thing is after countless searches I haven't found a single case of wet belts issues in the 1.1. Maybe because there are way less out there than Ecoboosts? Also, I found a video on YouTube from an apparently reputable guy talking about these issue. In the video this guy pointed out that the direct injection helps to the wearing of the timing belt..."something something cold start something solvent properties of petrol directly into the chamber something belt made partly of nitrile something something." Maybe since the 1.1 doesn't have direct injection it takes longer for the belt to wear? I asked about this at the dealership, the service manager still insisted in the 10 years/240K km replacement interval. 🤷♂️ 4 Quote Link to comment Share on other sites More sharing options...

Well, according to Ford (see link below ) the YouTuber was correct about the injection system. How much the DI on the ecoboost contributes to fuel dilution and how great the effect of that on the belt is compared to the other issues - missed changes, wrong oil, use of engine flush, etc - is an interesting question.

FordFiesta2017_FiestaDrive_TechSpecs_EU.pdf 480.86 kB · 4 downloads Regarding the missed oil changes, I've had them done with every service, that is, every two years or 30K km. Is that good enough? In my case, my car is from December 2017, and it's 39K km now, so only 3 oil changes in roughly 6 years. Last year I took it to the dealership to have the rear bumper repainted, and since it was going to stay there for three days, I asked to have the oil and filter changed. The service manager, after putting the order in the computer told me I didn't need it since I had it changed the year before (two years ago), and canceled the order. Other people, on the other hand, claim it should be changed every 8K km or every year at the very least. So, who's in the right here? I like my car, I really do, for just 85hp and 110N/m, it's not too different from my old 99 Escort 1.8 TD. Except that in that car, oil changes and timing belt replacements seemed to be optional, it'd just keep working fine. 😅 1 Quote Link to comment Share on other sites More sharing options...

So, who's in the right here? When I got my previous 1.0 (wet belt) ecoboost in 2018 I was surprised that the service intervals (UK) had changed to 18,000 miles**/2 years. No-one was able to tell me of any changes to the engine or oil specification to suit this, so I just stayed with annual oil and filter changes, as have many others on this forum. (** near enough to 30,000km so obviously the same where you are) 1 1 Quote Link to comment Share on other sites More sharing options...
Kolmo74 Posted August 31 Share Posted August 31 I was thinking... is it a lot of work to remove the oil pan? In man hours, $$€€££. I would need an oil change, of course, but I'd really like to know how's the oil pump looking. Worst case scenario, an independent tech is doing it for 900€. Expensive, but still like a 40% less than Ford is charging here. Also he told me he's doing a lot of Ecoboost belts lately, which makes sense. Was it 2013 when the EB engines first appeared? 1 Quote Link to comment Share on other sites More sharing options...
MCF Posted August 31 Author Share Posted August 31 Been driving a 1.1 from new for 6 years and clocked up just over 20,000 miles. The bi- annual services have been done yr2/yr4 and yr/6 is due now. Local dealer today offered me another brand new 1.1 and at just £ 17,500 I am seriously tempted to just stay with the n/a engine as I do less mileage now I have changed jobs and mainly urban driving. Mechanically,only ever had to replace the battery after 5 years. New car would be available to pick up next week which would save me a service cost. 1 Quote Link to comment Share on other sites More sharing options...

Basically yes, some of the press cars/demonstrators appeared late 2012 eg: https://www.autocar.co.uk/car-review/ford/fiesta/first-drives/ford-fiesta-ecoboost-10t-125ps 4 hours ago, Kolmo74 said: I was thinking... is it a lot of work to remove the oil pan? Quite a lot about it in this thread (there are several others): 1 Quote Link to comment Share on other sites More sharing options...
