It does appear the 1.0 eco boost issues have been dealt with but no harm bringing that cambelt change forward to 100k or 6 years old. Much like the 1.2 pure tech engine found in various Citroen’s, Peugeots, Vauxhalls and Opels it’s essential the correct oil is used when serviced. I would even go as far as buying the correct oil yourself and giving it to the garage if your using an independent garage. The wrong oil in these engines does make a difference.

Have some experience of this. We own a new MG HS which is meant to use 0W20 oil. There have been reports of other owners getting their vehicles serviced by main MG dealers no less and finding they have used 5W30 for the oil change.

;;;and what happens? The higher viscosity oil dissolves or busts the belt?

Not saying this couldn't happen, on an allegedly too-delicate-for-this-world "modern engine" but it seems...er...a bit of a stretch

Incidentally, I think its Ecoboom not Ecobang

So the answer is no

I am sure the latest are chain now not the old wet belt.

Apologies, my mistake, they are all belt as far as I am aware.

Edit: I thought they did change to chains but there is very little online. It looks like they may be chain from 2021 onwards (the hybrid versions) but I honestly canot be sure. I think the turbo has moved to the back on these versions.

My sons 2014 Ecoboost has just suffered a welt belt failure at 51k which is at this stage looking like a £1400 recon engine replacement ..........

I think there is much we do not know about the sourcing of cambelts by car makers. For such an important continually stressed item, high quality is of the utmost importance. The excellent PSA 1.2 puretech engine's reputation was marred by a poor quality batch of belts which crumbled. I have no idea who made them. If you search 'cam belt manufacturers' , seven 'well known brands' appear.

We had a Ford Focus whose high quality original belt lasted the lifetime of the car (21yrs and 162,000 miles), as it was designed to do. I suspect there are cases where owners, observing Ford's precautionary advice of changing it at 100,000m or ten years...or even earlier thinking they were being extra safe, had cheap inferior belts from obscure makers substituted for the perfectly good original one, which failed a few tens of thousands of miles later - quite apart from the risk of cack-handed mechanics taking short cuts and causing collateral damage, e.g.timing issues.
