Nipples On Intake Tube

JustROLLIN · 08-16-2004

OK, I am curious as to what plugs into both of the nipples on the intake tube. There are 2 large nipples stacked right on top of each other and I cant remember what plugs in there. I know that one of the two is the plug-in for the hose running out the side of the valve cover, but I dont what the other is for. Also, which one does the breather plug into? The top or the bottom nipple? Thanks for help on yet another noob question.

One is for the charcoal canister, the other is for the valve cover breather. They are both different sizes if I remember right but it doesn't matter if you mix them up. Tho one for the charcoal canister runs from under your battery to the intake tube. Hope that helps...

Yeah, it does help. So if I have removed the canister I take it I can just block off the other nipple?

Yep, I recommend blocking off both and dumping the breather line. I put a filter on the line and runn it to the ground.

I have thought about it, but I see no real advantage to doing that. I have the in-line fuel filter to act as a catch can. If there would be an advantage, lemme know, my ears are open. BTW, thanks for the quick response and useful info.

I just found out that the bottom nipple on my car has nothing going to it, so its just sitting there wide open? I guess my car came like that, because I didnt do it. Should I just plug both nipples? What do you mean by "put a filter on the line and run it to the ground"? Can't I just add a filter on the cover? I'm sorry, but I dont know much about those kinds of things. I only know the easy basics like the motor and stuff like that....

Yes, you can add a filter right on the valve cover, but it can make a mess over time. Sometimes oil will penetrate the filter and spray into your engine bay. That why I use an in-line fuel filter and still run the line back to the intake. But, maybe people who run just the filter will have a different opinion.

And yes, you need to plug the open nipple. Air is entering your engine through that nipple and is not being metered by the MAS. In turn, your car may be running rich. Make sure you plug that open nipple up.

When the filter fills up and starts messing, I just clean it out.

Wouldn't that make it run lean?

JustROLLIN · 08-19-2004

Yeah, it would be lean, I dont know why I typed rich. Thanks for the correction.

I dump my line to the ground to keep the parts on my car cleaner. Eventually the filter will become very dirty. When that happens, some of the oil can make its way past the filter and into the intake charge. When it enters the intake pipe, it goes through the turbo, throught the ic pipes and into the IC. Everything along the way is going to become oil covered over time. The ic will become less efficient and will heat soak quicker. That is why I dump it instead of re-routing it.

Khadgar · 08-19-2004

Yeah and when you have the breather get full, it does make quite a mess.

1slowdsm · 08-19-2004

That bottom nipple has been open ever since I got my car (1 yr ago), so I've been running a little lean all this time?Where does that bottom nipple connect to, maybe the hose that was suppose to be there fell off.
I think I'll just put the filter on the cover and block off those two nipples, it'll be easier for me. On average, how quick does it take for the filter to get filled with oil? After thinking about it, dumping the line to the ground doesnt sound like a bad idea. Both ways are almost the same, right?

Dumping hasn't caused a mess at all under my hood. Read my first post to see which lines are supposed to be connected and where they go. I have a filter even though I dump to cause a bit of resistance in the line.

JustROLLIN · 08-20-2004

I really havent had an issue with the in-line filter either. Change it out every 6k or so. But, to each their own. I may change my setup soon. How much do those little k&n filters run?

A//// Guy · 08-20-2004

I have a spare KN that anyone can have for 5 bucks...
I dont really like them because they leak oil right out of them and onto the thermostat housing...

It looks nice though.

JustROLLIN · 08-20-2004

Thats the point I was trying to make earlier. Those little filters make a mess everywhere.

No one else has had a problem with this?
