These seems to be similar:

Or this one, http://www.fordownersclub.com/forums...iss-in-engine/, but the guy never answered! (Dear future reader of my this topic, if I do find the issue, I will post it here so you can see it. Best, excalibur1491)
This one though, says something useful: http://passionford.com/forum/ford-fo...e-hissing.html
But I can't tell where that manifold is. I dont even know what the hell is that.

There can be a little blanking plug on the inlet manifold at the rear of engine on the firewall side, if it falls off it can cause a vacuum leak. Check with a torch and look for little pipe looking plastic piece, if you feel sucking air coming out, thats your problem.

Just a thought!!

Thanks for the idea!
I looked, and I couldn't see much. I tried o put my hand in different places, see if I could block something ant the noise stops, but my hand can't reach everywhere.... So I haven't been able to identify that.

I went to Fod, they told me to come back on Tuesday, they'll take another look. I'm concerned they'll break something else, but I see no other option than leaving it with them. I can't pay another mechanic!

The PCV(pressure control valve)is right on top of the rocker-cover & takes fumes from the engine back into the system via the inlet-manifold.But vacuum-leaks can be anywhere.Just tightening-up the inlet-manifold bolts can help.

Hi again!

Thansk for the help guys.
SInce I dont have many tools, the only thing I can test myself is the "rubber T piece" that dirty hands mentioned.
I have located the coil (not so easy for someone that know nothing) but I am absolutley unable to find that Tpart in engine.

Here are some pics.

Im looking for this, I am completelly unable to find it....

Can any one spot it in the pics? some images are upside down, because I put the camera as if I was looking from below. The arrow in one of them indicates the way "up" to not get confused.

Thans again!!!

Edit: Actually, is that Tpiece thing issue also in Ford Fiesta? I see it mentione din many places for the Mondeo Zetec engine. Is it the same engine as Ford Fiesta Zetec? Maybe its not there, but somewhere else..
Here https://www.youtube.com/watch?v=l7MUL3vtZ5o at 2:30 they put the coil, I can't see any T piece bellow :(

Sorry my fault.I thought your car was a Falcon but it's a Fiesta & therefore my advice is incorrect.All the best mate.

excalibur1491 · 21-04-2015, 06:37 PM

I found this diagram http://www.justanswer.com/uk-ford/3z...tre-inlet.html so Ill try to see today if I can get my arm there and see the PCV valve by myself.

But, as a matter of fact, the hissing might be normal...
Mine is the entire oposite of a Ford Expedition in size, but still, here http://www.automotive-emissions-trou...eshooting.html they say "if the PCV valve doesn't work you might not hear the normal hissing".
lol, I don't know what to believe any more. I'm going crazy lol
