Scotty, what’s your opinion on the new 1.5 Ecoboost 3 Cylinder made by Ford which are in the new Bronco’s, and the new Fiesta ST in Europe? It has dual injection, port and gdi so I can’t see it having any carbon build up issues? And is driven by a chain rather than a wet timing belt. But would be interested to hear what you thought on them
2019, Ford Fiesta ST, 12,500 miles, Manual
I was personally very interested in that engine, I was considering a Focus ST but,
the "EcoBoost Dragon" sounded too good to be true - and it is.
There's a reason why these engines are called "EcoBOOM", specifically on the 1.5L:
- Ford after all these years still can't solve it's fuel detonation issue!
- BUT that's very minor compared to how these engine blocks crack (like on the 1.0)
- Also funnily enough although they have that dual fuel injection system, they have some of the worst carbon build up issues - unlike most normal engines, on this one it's on the exhaust side.
As far as I know they still have timing belts but I could be wrong on that.
Also this being a Ford, be ready to adjust your valves at 60k miles as they cheeped out on Hydraulic tappets.
I REALLY don't consider this to be a good engine - I would not keep one past the powertrain warranty period.
Don't get me wrong - I like Ford products, I own two cars with their engines and am really happy with them.
Back in the day, the old ST products that had a Miata L-series engines, those after it that had a Volvo Modular engine - but on this generation they cheeped out in the worst way.
Ford just turbocharged an existing engine - And the result is worse way than what a high-schooler could do on a budget with a 20 year old Honda Civic.
@legendaryslayer Thanks for letting me know of this question.
You're welcome my good sir.
I'm not a fan of any of the EcoBoost motors. Reliability is sub par in the long haul.
I live in the US. I am not sure if they have the same problems in Europe. IMHO, turbochargers are one of the major components that will go out. Also, engines are also another major component because ramming air into smaller engines equals wearing it out faster. So I wouldn't buy any Ford products at this point.
Some issue with them the turbo being the main. I've also been hearing the internals wear fast and valve cover gasket and manifold gaskets breaking. This is for usa spec not euro. Have no clue if there the same. I'm sure someone else will comment who knows both cars
