2013 125hp 1.0 Ecoboost, loss of power and white smoke.  Absolutely stinks of petrol.

I suspect head gasket or turbo.  In the case of the latter any ideas how much you'd expect to pay for a replacement fitted?

I suspect not worth spending the money to fix the engine as the wet belts are due for replacement (unless of course you have just had them done). The cost of trying to repair the engine plus the belt replacement will be around £2000.

Thanks.  Sods law I spent 800 in January getting the belts done, water pump etc.

Why do you suspect the head gasket or turbo? Are you assuming that the white smoke equates to burning of coolant and thus suspecting a coolant leak in one of these two locations? I don't yet have the commonly associated causes of differently coloured smoke engraved into my brain, so I had to look it up, and although white smoke is most commonly indeed associated with burning of coolant, there are other causes too; White smoke that stinks of fuel could actually be unburnt vaporised fuel, supposedly.

In fact I came across a discussion about an ecoboost, similar/same symptoms, plus a couple of DTCs, that turned out to have a bad fuel injector.

If one or more of your fuel injectors were misbehaving, wetting the spark plugs and thus interfering with their ability to ignite the air-fuel mixture, could this not thus result in a white "smoke" stinking of fuel? (There's also mention of black smoke sometimes being from an overly fuel rich mixture, but in that case the mixture is still being ignited). Or alternatively could there be an issue with one or more sparkplugs / coils?

This explanation also accounts for the lack of power, whereas the idea of burning coolant accounts for neither the lack of power nor the fuel smell.

White smoke can also be unburnt oil in the case of a blown turbo oil seal on the exhaust side.  Though if it stinks of petrol, it probably is petrol.

Injector would be my first thought here as well.  Get it plugged in to see if there are any fault codes in the first instance.

First thought was turbo - loss of power and no smoke.  Few minutes later the smoke started which lead me think head gasket.  So yeah, a coolant leak is what I was thinking.  Coolant level looked fine tho which made me think turbo again.

After posting I read about a possible cause being the fuel injectors, so yeah, good shout.  I don't think iffy spark plugs would result in white smoke?  Hoping someone tells me otherwise, cheaper fix! 

Could be one failed spark plug.  Though the PCM should detect the misfire through lambda and shut-off that injector.  It'd sound different running on 2 cylinders though, and you haven't mentioned any sound change?

If you've got the tools and a spare 10 minutes, there's no harm in pulling the plugs to check them.  

Was a faulty fuel injector.  I'd feared the worse!  Ecoboom lives to see another day.
