The intake manifold doesn't have oil fumes going through it, it has clean air direct from the throttle body (which has been filtered by your panel filter or induction kit's air filter). Unfortunately I don't have a specific picture of it in my car, but this is it: ![](http://i372.photobucket.com/albums/oo165/fordfiestast_co_uk/Album%20Eleven/YD8031.jpg)

that's what I tought mate, but it hasa connection between engine and intake manifold. some kind of a valve, pcv or something like that that you need to remove from the engine, plug the hole on the intake manifold and then take a hose from the place where that valve was and stick it to the OCC. that's what the guy explained to me. thanks for the photo ;-). cheers.

There is a breather from the block to the inlet so it is likely there would be vapour in the inlet.

I don't run that breather to the inlet. I don't really fancy dirty oil going into the engine. I just have a breather filter on the breathe hole at the back of the engine. The only real reason to have it going into your normal air filter is to negate the need for a separate air filter and it also helps build a bit of pressure for the breathe hole to operate. Although separate filters look the bees knees imo and are only a few quid on ebay.
Stason, yeah, that is the oily mess that has built up over a long time. To stop it you have three choices:
a) just bang a filter on like I have, pros are it's cheap, cons are the filter might get oil in it eventually. b) Attach an oil catch can inbetween the breathe hole on the engine block and your induction to catch the oily fumes, pros are stops the majority of the oily mess getting into the engine, cons are the cost of an oil catch can and the risk of some fumes still getting through. c) Combine A & B in the form of an oil catch can connected to the breathe hole which then runs to a separate filter. Pros are no chance of oil getting into the inlet, cons are a potential lack of pressure for the breathe hole to suck fumes out.
Interestingly I ran the car with no filter on the breather at all for a little bit and no oil came out at all. I don't think our engines breathe very much compared to say the older VW engines which spew oil everywhere.

I think this is because you get most of the cr*p from the other breather (or whatever it is called) between the engine and inlet manifold, at least that's what I understood. I'm trying to get as much data on this cos if this is true I would remove the manifold, cleaned it and redirect this "line" to the OilCatch Can. BTW I'm not running my "upper" breather back to the intake after passing thrue OCC, but I also didn't notice any oil/grease going out, only slight pressure. cheers.
what is the exact name for these 2 breathers in our engines?

on the 1.4 mine breathes out rather then in... apparently this is an age related thing and is something to do with a floating crank

I don't understand? as I'm aware, it always breath out from that pipe on top of the engine?

I think it can breathe either way, i'm not absolutely sure but when I put my finger over the end of the pipe at idle it felt as though it was sucking slightly.
Whereas when you rev it breathes out, hence the oil residue.
When you connect the pipe to your induction kit, this creates extra vacuum to help the suction.
