Ford EcoBoost 1.0-litre timing belt runs in oil

I could see this catching on if the belts are made to withstand all the snake oil that people seem to love putting in their oil. The belts will definitely run cooler and encounter less friction.
 
No thanks! The Honda 1.8L 4 cylinder is a much better engine and is chain driven.
The same timing belt setup is used on the 1.5L Ecoboost engine. With the 1.5L Ecoboost the belt must be changed at 150,000 miles.

they still use timing belts?

Exhaust manifold molded in to the head - no thanks. Engineers are doing anything possible to get that last 0.01 MPG.
 
Not the worst idea ever conceived.
You heard it from me first: Timing belts will be making a comeback in future engine designs, like it or not.
I mentioned before the auto makers have engine designs in the skunkworks for the 2025 EPA 54 MPG requirement that is looming.

Thats an emissions move actually. Also one less part to make and less noise transmission
 
Honda was the first to use a belt in oil - but on a much smaller scale in their OHC small engines. But then again, Ford and Honda have different ideologies.

Why not a chain?


Too expensive, heavier and most importantly, noisier
 
My owner's manual says that the belt can be changed at 150,000 miles, IIRC. It looks about a difficult as most timing chain jobs.
This is a seriously quiet engine. It is so quiet that rev matching downshifts is a PITA. I want more noise.

"Can" or should be changed that early? That's interesting, because I thought Ford's line on these initially (when the 1.0L was introduced) was that the oily belt is good for the life of the engine, and isn't expected to ever be replaced. Of course, that could be another way of saying the engine will last only as long as the belt.
 
The owners manual of my 2015 Focus 1.0 makes no mention of replacing the timing belt.
The 2017 owners manual says at 150,000 miles “Replace timing and oil pump belt (1.0L engine).”

Actually, a well designed integrated exhaust manifold is an effective setup for a turbo. Ford has done a great job managing airflow on the exhaust side, by directing the exhaust the proper direction right after the valves and smoothly merging them to the scroll.

Put another way, it's easy to redirect the exhaust flow immediately downstream of the valves, instead of forcing a sudden right angle change via a bolt on exhaust manifold. Sure, an equal length turbo header makes the most power. But that's something manufacturers don't typically due.

I wouldnt mind one of those engines in the ecosport.

able to tow 2000lbs..

Subaru take note your 1500lb limit on the forester is way too anemic.. esp since same vehicle overseas can have over a 4000# rating.
Granted I rarely towed over 1500lb.. except on scrap runs. no reason did they need to lower it from the 2400 limit on the 2009-2013 models.

Too bad you cant get a 6mt in the ecosport to go with the engine.. also the fuel economy seems low for such as small vehicle.

Would be great for city parking though.
 
Interference engine, or not? I'm OK with a timing belt as long as it's not an interference engine, like my Escort where I've had numerous timing belt issues over the years (since 1985) and never had engine damage when a belt goes.
 
With my annual mileage, a 150K car will be a good 15 years of driving on northeast salted roads. Engine may be good, but the rest of the car will be getting old. I would risk not changing the timing belt.
