Hi, I am considering swapping my mk2.5 ford focus 1.8 for the above.
Quite like the idea of the 1.0 for the noise and fun factor. Are the revised chain driven cam engines more reliable than the older 1.0 ecoboost with the wetbelt. I understand the revised engine has a wet belt for the oil pump drive. Or will I be better with the 1.5 ecoblue diesel for long term reliability. Cheers

I'll be keeping an eye on this as my own MK2 1.8 focus won't last forever.
My worry around the three cylinder engines that when my folks had one in a 2013 fiesta it felt a bit "rough and ready" and was mated to a tall and widely spaced ratio 5-speed 'box. It'll be interesting to know if the focus installation is any better

My dad had a 2012 ford focus 1.0 ecoboost he had it for ten years the engine was a little gem very smooth and felt strong for the 100bhp version. No problems but was serviced on the button. My brother in laws 1.0 has overheated but survived when the degas pipe went. But I know a lot haven't been so lucky with them. My focus is feeling its age now.

It'll be interesting to know if the focus installation is any better Loss of engine power and serious valve damage is commonplace on higher mileage EcoBoost engines. The EcoBoost engine features only direct fuel injection with no fuel to naturally clean leading to a build up of carbon on the intake valve stems which restricts airflow. High-mileage EcoBoost engines also can suffer from fuel pressure problems. Low pressure produced by the fuel injector pump restricts the engine hampering its performance. This can often be resolved by simply replacing the fuel pump. The most significant and notorious issue with EcoBoost engines is related to overheating. Early Ford models fitted with EcoBoost engines had coolant pipes made of nylon which were to prone to failing at high temperatures. A Field Service Action (FSA) was issued in March 2015 which saw Ford replace the pipes of 96% of 44,682 affected vehicles. |

That info is related to wet belt ecoboost, the degas pipe recall was a good one for the dealers, if there was any leakage or cracks in the pipe then it was new engine time. The engines themselves were very low cost and with no repair parts made available save for the peripherals. I have no experience with the newer ones but stay away from the wet belt ones. - another fun fact, oil additives sold as service add-on's by the dealers shortened the life of the belts by quite a bit... Until they were reminded by Ford of the prohibition on fuel and oil additives unless explicitly required by Ford technical.

We have rebuilt a lot of ecoboost engines in house here - so many we have an exchange unit in house - (repair it/fit it/then repair the one that came out for refitting). Bottom crank bolt is "murdertight" - replacement has diamond faced disc that goes in to stop it slipping. When I say "murder tight" I mean torque multiplier tight - "FT". |

I know you can get bits for them now, it was 2014-16 when I was in a Ford dealers and they were not designed to be rebuilt (aftermarket says different!) but they really are a 'recycle' engine. We had a guy turn up with one out of the vehicle wanting (I think) the crank pulley bolt taking out and assumed we'd have a crank locking tool, IIRC we just warmed the bolt to 75degrees with a plumbers gas torch and rattled it out with a 3/4 buzz gun....

Decent 1" drive gun fed thru a 13mm bore pipe will get them off "cold". I would agree - these are "designed to be disposable". |

Wasn't the ford sigma engine said to be a throw away engine ie you couldn't rebuild it.

The Ford Sigma is a small straight-4 automobile engine introduced in 1995 by Ford Motor Company. Its first evolution was sold as the Zetec-S (not to be confused with the trim level), then Zetec-SE and finally, in later years, renamed Duratec
When the Zetec-SE first arrived in 1995, it included many firsts, such as a plastic inlet manifold, a "ladder" style main bearing and crankcase assembly, and big-end bearing caps which are forged in one piece and subsequently split. It also incorporates powder metal connecting rods, which were quite exotic and notable at the time. This feature however makes the engine more challenging to rebuild at the end of its working life, since it is not possible to re-machine the bearing ladder as would be the case with a conventional cylinder block - the entire assembly has to be renewed….

Just an update bought a mk4 1.0 ford focus 125. Can confirm it's a very nice smooth sounding engine. Surprised me how powerful it was definitely quicker than my old ford focus 1.8. In terms of reliability time will tell. Thanks for your comments.

Me neither, in fact any 3 pot engined car…POS…. My 3 pot is 20 years old, 60+ mpg, gets me to work in a similar time as previous TT that used twice as much fuel and cost 12 times more in road duty / tax. The £1k plus saved will cover extortionate increase in electric/ gas makes it worth it even if I look a tw*t driving it 😆 In the meanwhile Co workers buying flash motors on credit or leasing fight over the overtime list, it’s not what you earn so much as what you’re spending it on… |
