Mk6 fiesta 1.4

When it's cold not a problem, but as soon as it's up to temp there is a breather pipe that is pushing vapour all over the place, at night you can see the mist in the headlights
Thing is, you can't see it during the day

So, is there a known pipe that splits or do I need to look through them all?

Cheers

 

no one?

 

Use a leak down smoke tester to find the leak whilst it's hot during they day?

 

What's one of them then?

And will it work on a breather hose that isn't pressurised?

 

the breather pipes are very easy to get to on them dojj im sure a man of your calibre can easily find them! but if not they are right under the inlet manifold and tend to go very soft with the oil and then split

 

I'm going to investigate with the help of the trusty Haynes book of lies then

 

got a video of it hot AND cold

loading them up now to youtube so peeps can see whats going on

when it's cold, removing the filler cap raises the revs BUT removing the dipstick makes no difference at all

it's also got lots of oily deposits around one of the pipes so i'm assuming it's a breather pipe thats blocked sending all the pressurised air from the head out into the atmosphere

sound about right?

vid will be up in a bit

 

 

and this is what it looks like when it does smoke

 

no one at all help me out?

when i open the bonnet, no smoke, when i close the bonnet, smoke

 

Leave the bonnet slightly open and run it like that, problem fixed.

 

might just remove it altogether in that case

 

Breather pipe is near the dipstick look in between the inlet manifold you will see it from the top it will look ok but mostly split on the underside and go very soft pair of long nose pliers and some patience

 

From experience the common breather pipe to fail is near where the throttle body goes on the left if you can see the small pipe running to the right but double check to make sure it's goosed

I have also had to change these manifolds as they split on the seams as well





Goodluck

 

Give that man a round of applause!!!!! It's split right where you said it would most likely be

New pipe is in stock too at the local dealers so out I go to get it

 

Any idea what part number is for the breather pipe that sits just to the right of alternator as you look at it?
might be an oil breather pipe
