I have a ford fiesta 1.1 HCS push rod engine with single point injection.
I had blue smoke when revved hard so I have replaced the Head gasket and valve stem oil seals.
I have tried swapping map, o2 sensors.
I had a smell of egg so swapped over the o2 sensor.
The car run's rich as you can smell it.
I can either get white smoke or blue smoke by swapping sensors.
I used to have alot of blow back from the oil filler cap but thats sorted since I replaced the valve stem oil seals.
White smoke indicates water but I don't know where its coming from, if its leaking at all.
Has anyone had the same problem???

 

Is it using water ?, as this time of year they all smoke terribly when cold.

Not sure at the moment. I've just put a secondhand engine in it.
Its got no t and t so a road test would be risky. I need to get it through an mot for my wife to use.
I reckon the map sensor, cat or o2 sensor is duff that is causing the over fueling.
White smoke - Cracked head or block, Could be the inlet manifold not sure.
Tomorrow I'm going to break out the multimeter and start checking everything.

 

i have a 1.1 fiesta hcs let me know if you need out as am brakeing it

 

OK, Cheers mate. I have quite alot of spares but If I need some thing I'll give you a shout.

 

I would put a new CTS in as a matter of course, to start with.
This is the main factor governing the co, so needs to be right.
I did a festa last year a r reg one(1.25 zetec se) that was one of the damaged ones from Tesco petrol, and had been like it a few years, only a new lambda on that DESPITE it showing correct on gagues/metres, was switching way too slow, wasn't able to check speed with what I had at time, so took a chance.
