Broken piston 1.5L ecoboost

[StockEngine]

It was changed around mid December last year. They used Shell Helix Ultra AF 5w30.

ah kaya pala covered.


i have a feeling hindi pinalitan though. that oil looks kind of dark after 60days. is that your daily driver? ilang kilometers ran after that oil change?

Hindi ko din kasi nakita ang pag change oil niya. But I noticed smoother performance after the oil change, so baka naman pinalitan.

Its my daily driver. Ran for about 800 to 1000 Km siguro after the oil change then this happened.

Burning oil is a sign of broken oil control rings, damaged piston ring grooves or worn cylinders. Or broken pistons.

When you say "short block" that means an engine with NO cylinder head cover, starter, alternator, etc. When you say "long block" it means an engine that just needs bolting in, an almost complete engine sans intake manifold and exhaust manifold. So saying to make sure the replacement engine should have a short and long block together does not make any sense.

Not sure who supplies their pistons. Maybe they are manufactured in house.

This might be a one-off case, or this might affect other 1.5L ecoboost as well. Who knows. Ford said they will be analyzing what caused this. My only problem is I don’t have a car to drive now. Pwede sana magpahiram sila kahit Fiesta man lang. 😂

Kung manufactured in-house ang pistons nila eh malaking problema yan.

yep. burning oil will also have obvious give aways like blue smoke. my uneducated guess leans me toward maybe an unseen defect sa piston na nakalusot sa quality control.
nga pala curious lang is the car an automatic?

The local Focus 1.5L Ecoboost only came with a 6AT tranny.

Demand Ford to replace no less than a B'new egoboost motor, whole engine in crate

ecobooooommm...

kakatakot naman factory defect .palit nalang dapat ng buong makina..

Mas maganda nga buong sasakyan.
Wala pang update ang Ford kung ano na ang gagawin.

By the way, just posted this sa Focus club. Meron na din pala nagkaroon ng ganitong problema. All in all, 5 na focus including sa akin ang alam ko na nagkaroon ng issue na ganito. Naayos na daw yung iba, pinalitan lang daw ng cylinder head assy.

There really is a factory defect sa batch na ito. Dapat may recall or announcement ang Ford.

A good friend drives a Focus Ecobooost told me he knew of two other people who had the same issue. One is from a heavily modified engine while the other is stock. He is complaining that he is experiencing oil burning with his 1.5L Ecoboost engine.

Bro, I have a question. Did your friend and the other owners drive their Focus hard during the break in period?

I just remembered when my dad and brother test drove and borrowed mine, they said they drove the hell out of it to “test the capabilities” and even reached 160km/h... from what I know, one should not exceed 100km/h during the break-in period...

Any input from them would be great.

I am not sure how hard they drove their Foci during the break-in period but the only thing I remembered from Ford when I got my Fiesta is that I should not try to hit redline during the break-in period. Ecoboost engines are rev-happy and it's hard keeping it below 3k rpm specially when the turbo spools already.

The Focus can easily do 160kmh, even 200kmh will not stress the engine at all. I guess your dad and brother have not tapped the full potential of that 1.5L Ecoboost engine. Once that engine is fixed, give it a go and flex the legs of your car. Just make sure the road is open.

Oh boy, they definitely redlined it. Paglabas pa lang sa casa, I let my father drive it and he went full acceleration agad.. I myself am guilty redlining it within the break in period since I thought the period ends at 1000Km instead of 1000 miles, yun pala 1500Km according sa manual.

I think I’m now having the idea that maybe the car wasn’t properly broken in... of course all of this is only theoretical... but I won’t tell the casa though. Baka ako pabayarin. 😂

This is true... coming from 1.5m/t ecosport, i tried to test their ecosport with ecoboost, swabe ang tubro di mo akala sa bigat ng ecosport... pero yun nga nga abot ng 3-4k rpm though gaan parin ang ramdan ng engine... i wonder kung ano na kaya sa fiesta... sarap ng feel siguro...

With my old Fiesta Ecoboost, the engine idles at 1k rpm and the turbo spools just before 2k rpm when properly warmed up. However, when the engine is not yet warm, turbo lag is evident as you need to rev it a bit to 3k to give it a go.

At full acceleration, the Fiesta 1.0L Ecoboost can do 0 to 100 kmh in just ticks below 10 seconds. They say the Fiesta Ecoboost is good for 200 kmh but I have not tried it at that speed, only 180 kmh.

Anong fuel laging gamit mo?

Anong fuel laging gamit mo?

Mostly Shell V power. Sometimes Caltex platinum. Manual recommends 95 octane or up.

Just visited the car yesterday, the engine was open. Here is what the piston looks like.

That piston sure looks like it suffered a catastrophic failure. It might be the piston design.

Yeah. Might be a factory defect talaga. Pero kapag may bago ng engine, I’ll just break it in properly this time just to be sure. No more screwing around. 😂

[Janemar]

Ringland failure, cause is usually detonation or weak piston talaga. Either bad batch ng piston or bad fuel + heavy driving. I would switch to blaze100 if I were you for extra insurance.

No form of break in can save your piston ringland from cracking. Ang binebreak in mo lang are piston rings to seat properly sa cylinder walls. If improper breakin, you get high blowby due to poor sealing and not cracked piston.

Yup, actually plano ko din yan once I get the car again, I will use blaze for that 100 octane. Still, I’ll be playing safe this time, break in ko na ng maayos para iwas sa possible issues and maybe not abuse the engine too much for prolonged periods of time. Yes, faulty ata yung batch ng piston nila, I’m not the only one who experienced this issue.
