I recently discovered the issue that the 1.0 ecoboost uses a wet belt, I had no idea.  I was also blissfully unaware that anything other than a squeaky clean service record with Ford would be tantamount to useless. However the worst happened and my engine oil strainer became blocked and out of the blue it failed catastrophically.  It was towed to a garage where they said the engine would need replacing and that there are a number of items that I would need to replace to maintain any future warranty on the new engine. So I fork out for;

New engine

New turbo

New clutch (had issues with the slave cylinder so this made sense) 

several supporting parts.

 

Roll forward 2 weeks, the work is complete and I collect the car, all seems well. Until it then out of the blue fails to start, it cranks, there is fuel but no spark.  AA take a look and can't get it going so take it to a local garage, they can't find anything wrong with the engine, the work but have some odd behaviour where if they remove the spark plugs and refit, it will run for a little while and then stop.  We decide to have the ECU tested, and that comes back with no errors or faults.  

When the ECU is plugged back in, lo and behold it bursts in to life and runs for the next 2 or so weeks covering at least 3k miles.

Then, it fails again randomly, I tested the ground, seemed fine no more than 30mV lost over the chassis to engine ground, replaced the air filter and ran a diag with Forscan.

The Forscan showed coil issues in A,B and C, so I replaced them, no luck

reset the codes, tried to start, but battery was struggling.  Had battery tested, and that was awful so bought new battery.

It then runs for say a days worth of short journeys and now has cut out again!!!

Literally out of ideas, any help or suggestions would be amazing.

Take the car back to Ford and make them fix it. You have warranty on all the replacement parts

Hi DaveT70,

Would that also apply to a Ford supplied engine not fitted by Ford? The garage (annoyingly 125miles from home) said that Ford wouldn't warrant the engine if I didn't also have several ancillary parts replaced, which I did.  I assume that would mean that the parts themselves are warranted for defect from Ford, but the actual work is only warranted by the garage that did the work.

Thanks in advance.

You would have to allow a dealer to investigate to see what is causing the issue. If one of the new Ford supplied parts that has been fitted has failed due a manufacturing defect (and this has not been caused by incorrect installation) Ford will cover the cost of both parts and labour if the repair is completed by one of there dealers.  You will have to supply your invoice's for the work along with copies of part purchase invoices from Ford (including oil invoices) that the garage who completed the repair will have.

Yes, all parts are warranted from date of invoice

Hi Pommeroot,

have experienced similar issues myself, like you I was blissfully unaware of the wet belt and the issues this could cause, had been having issues with the vacuum pump but when the one way valve went on this the Engine service now advisory appeared on the dash and the engine went into a lower power mode.

with the wet belt issue for a couple of days before the oil light had been flickering on and off,  so dipped the oil and this was as it should have been, didn’t think anything was an issue, luckily I was driving past my usual garage when out of the blue the engine management light came on the engine power dropped, so pulled the car over and handed them the keys.

after hearing it was the wet belt that had delaminated and blocked the oil conduits I had this changed and the engine cleaned out.

As all the associated parts had also been changed with this, when the car came back to me it drove great for a couple of days and then started cutting out usually when in a traffic jam, the car would drive great then all of sudden it would go to stall, no reaction when you pressed the accelerator.

after a lot of head scratching an autoelectrician diagnosed that the low pressure fuel sensor needs to be changed. This takes us to a week last Friday and to date, touch wood, no further issues.

hope this helps

Hi Andy / FGT

It seems the one way valve is *another* common issue.  This had already happened on mine, luckily there are aftermarket solutions, so replaced and all was good as new.  That was until the belt clogged the oil pick-up strainer.

The flickering oil light happened to me within about 5 minutes of catastrophic failure!

I've had the car looked at by 2 mechanics and both think it could be a wiring issue caused by poor re-routing of the harness.  Not clipped back properly and one cable going under the engine mount.

Since my initial post I have had random comms issues on the MS1 bus, but your low pressure sensor is interesting because I was getting -1.8Kpa (unless that is correct)

 

Thanks
