Re: Focus Inlet air leak?

Hi Chaps

I've just had a look at a neighbour's 1998/9 Focus 1.6. It's running
badly- the idle is a bit shaky and it's down on power. I did try to get
some fault codes out of it with VAG-COM in ODB-II mode, but it complains
and says the car isn't ODB-II compliant. Is this to be expected?

Anyway, a bit of hands-on investigation gave the sound of an air leak
around the passenger end of the engine- in the vicinity of the pressure
regulator. You can hear it with the engine running, and it's very clear
when you turn it off- there's a hiss for a few seconds. The way the car
idles and drives supports the air leak idea too.

We've wiggled hoses to no avail, and even tried the old 'spray it with
wd-40' trick (no plus-gas to hand!) to see if anything changes. Nothing.

Is there a common thing to look for? I did wonder about the manifold
itslef- it's plastic- but that looks a bit fiddly to get off to just look
at. The inlet trunking *looks* ok too, but we didn't remove it.

Thanks

Chris

mondeo with similar engine suffers from a little breather pipe that holes
itself, it is where you describe, for easy access the coil pack has to come
off.
