If you look closely you'll see that it is actually another hose that is completely separate. The other hose that goes to the idle air control valve is actually a hose that carries coolant. It comes from the coolant pipe behind the block. This is there to gather as much heat from the engine as possible to get it up to operating temperature as quickly as possible (emissions reasons) and for some cars it goes to the fast idle thermo valve that raises the idle while the engine is cold. There is a piece of wax inside that when cold allows more air into the manifold. When it gets hot it the wax expands and closes the opening, thus not allowing additional air to the engine.
So what do I do with this, it's kind of connected to the same breather hole, it'll put pressure back in the hole if I don't disconnect it from the manifold.

Yeah. I'm thinking about a catch can setup. Do all of them come with a breather kit? Sorry I have very limited knowledge on this subject. One thting that concerns me though is that I will be boosting a stock LS motor, and my main thing is that it can last and be very reliable, trouble free. Also one of the biggest concerns is the crankcase venitlation of course (what this thread is about, lol) So I am contemplating running a good catch can setup with a breather. Besides the endyn kit which I think goes for about 160 bucks.

Does anyone have any experience with a setup like this, or any other catch can/breather setup. I'm looking for something that works great, which I'm sure the Endyn kit does, but I'm also looking for something waaay less expensive.

Thanks.

yes. the only thing a catch can does is contain all the nasty oil and grumy ---- that would otherwise go back into the air intake, or go straight out into the atmosphere. depending on what you have setup

beau got kicked out at the track before for having his line spraying all over his front tire lol

I wanted to see what type of breather setups, and catch can setups work. Which ones were of quality and if some had better experiences with certain catch cans than others. Or it really doesn't matter. I can buy an ebay or make a homemade catch can myself, and they will all work easily. So pretty much the only way is either to ven to atmosphere or into catch can.
