Oil belt drive belt shredded Focus 10. EcoBoost 2019#

Featured Replies

Following on from my previous post and 4+ weeks later.  The issue has been confirmed that it is the Oil Pump Drive Belt that is shredded which in turn has killed the turbo (and not teh wet belt as I was first told).  Dealership have been appauling but that is a story for another day.  Full service history.

£2.6 to fix plus the £800 I have paid in hire car fees over the last month.  Ford have offered 35% towards the fix of the cost. 

However they also confirmed that the belt should last 144k miles or 10 years.  I have asked them to go and reconsider the case next week.

Any advice?



The oil pump belt is a wetbelt.

£2.6k sounds cheap for a new engine.  Is that just a new chain, belt and turbo?  Are they hoping that the lack of lubrication won't have damaged the top end of the engine at the same time as the turbo?

I doubt you'll get any more goodwill than 35% but no harm in asking.

I have been on this forum for 5+ years, the number of stories I've heard about wet belt disasters is just awfull most demanding the replacement of an engine. It is only by sheer luck I'm not in the same boat as I'd never heard of the issue before getting my Focus.  I could just as easily have bought the 'wrong' car.

I genuinely feel so sorry for all those that were conned by Ford in buying a car unfit for general purpose. It's certainly made me very wary for my next car to do some research before purchase...

Not just ford. Peugeot got a the same issues with there 1.2 petrol engine. 

And even Honda with the 10th gen (I think) 1.0 Civic.

Electric the way to go. 🤣🤣🤣

Can someone please tell me what the difference is between the wet belt and oil pump drive belt?  I am not a car person so really confused.

Are they just two diffetent belts part of the wet belt system?  As such it is a wet belt (just the oil rather than timing belt/chain) - as such it is part of the known issue

 

As Tom said they are both Wet Belts.

One is large and drives the Camshafts and on some cars the Water Pump as well.

The other one on your car is smaller and only drives the Oil Pump.

I'm assuming that your car is an 1.0 Engined Automatic. If so then as far as I know  these have a Balance Shaft as well and a Tensioner on the Oil Pump Belt. As far as I know the Tensioner fails and strips the Belt Teeth.

Someone else may be able to confirm if my understanding is correct.

There is no difference whatsoever.

A wetbelt is any belt that is bathed in engine oil inside the engine.  As opposed to a conventional dry belt that is outside the engine.

On the early 1.0 EcoBoost, there were two wetbelts.  One for timing.  And a second for the oil pump.

On the later engine (which you have) the timing is done via a chain, so there is only one wetbelt, the one that drives the oil pump.

 

It is part of the known issue, but crucially NOT covered by the extended goodwill, which only applied to the earlier engine with two wetbelts.

We now have access to Mk4 parts catalogues and can confirm that those do still use a balance shaft.

And, it appears, a tensioner which is the part which failed in the earlier version, leading to the recall in the US. 

Ford claim the reason there was no recall elsewhere was due to hardware differences but they never specified what they were and we've not been able to find any (unless it was a faulty batch or incorrect assembly at the engine plant supplying the US market).

I can't access the Parts Catalogue just now, is it only the Auto or the earlier Engines that have the Tensioner?. 

All the 1.5 Engines have the Balance Shaft but only the early ones have the Tensioner.

I'm not sure when this parts catalogue was 'borrowed' from Ford, it definitely isn't fully up to date.  The info we can access suggests that it is only auto's with the balance shaft, and that all autos with the shaft have the tensioner as well.  This is the bottom half of the screenshot above.

Thank you Tom, that was my understanding as well but we both could be wrong.

How do I know whether I have the older enginer or the newer one with the timing belt - I have just look at my VIN and it shows - 2020 Focus (2018)

It was firsddt registered in September 2019 it is Auto.  I know it was redesigned around this point - or am I just going down a rabbit hole.  I just like to know as much as possible going into these things

All Mk4 Focus have the newer engine.  (Unlike Fiesta where there was a large crossover)

Yours is definitely the chain engine.  With only one wetbelt for the oil pump.

Me, myself and I. 🤣🤣🤣

After spending 45 years working on these bags of ***** petrol and diesel cars, I know a thing or two what makes are good and what's not, what model is good and what's not, what engine is good and what's not. You get the picture. 🤣🤣🤣🤣🤣
