Are you talking about having the oil fumes recirc into the intake? If so, burning oil will reduce the effective octane rating of the fuel being used.

im more curious why people leave these open to free air, and dont have a baffled closed setup that has vacuum pulled from the intake. if you want to get rid of positive pressure in the head, pulling it out would be more effective than just venting it.

I've yet to see a vacuum setup that will keep up with a big hp turbo setup. I know our 5 stage dry sumps still have crankcase pressure unless we vent them...

It's not expensive.... The vac pump method is expensive. I would not use the suction from an intake for a vac source.... plus that would only work for NA unless you took a source from the turbo inlet.... then again who wants crappy oil going to their $1000+ turbo. Not me.
Think about that.
So how is there no positive effect to this? Please elaborate.

no, just utilizing a good filtration system/collection tank, possibly an exhaust setup as well.
theres probably tons of ways to accomplish something if one thinks hard enough about it.

didnt say there wasnt a good side. was just saying it might possibly in some cases not turn out like youre thinking. or as well as it could be.

Re: (tepid1)
im still not so convinced how a vented valve cover setup is any different than just putting a filter on the little port on the back of the valve cover, other than looks.
youre not getting any forced flow in either case, so how are you expecting anything to happen different between the two, except looking cool at the local meet.

Actually if you think about it with larger hose velocity is slowed down and is less likely to carry oil with it. A smaller tube will have higher flow of air and is more likely to carry oil as it vents from the crankcase.

Wow... You obviously know what you're talking about. All of us with these expensive evac setups just do it for fun. Pro drag racers, they just do it for looks at the local meet too.
Listen douche bag, for those of us that have REAL boosted setups and not just a little 6 psi turbo kit have something called Excess Crankcase Pressure. When you have this you get this bad little thing called Blow By (not blow jobs like you're used to giving). Blow by is when oil passes the barriers of the piston rings causing all kinds of problems. Not to mention all the other things that have extra stress on them do to this. The little filter that you mention works for venting stock setups but if those of us with real power just used that little filter we'd have oil spray all over our engine bays and that would be the least of our worries. We have to use the big lines that you see to allow enough air flow for the pressure to vent out of the motor. And in some instances oil travels with this vented pressure which is why we have "catch cans." This gives the oil somewhere to go while the pressure vents to the atomosphere. So before you go accusing people of doing something "for looks" do some research.

Re: (tepid1)
thats not near what i was asking at all tepid.
other guy:
i was by no means trying to make fun of you, or offend anyone, just ask a question and get an answer. your post was totally unnecesarry and rude. but good job being another jerk on this forum.
anyways, what im asking then, is whats the purpose for the lines and catchcan in that case, you could save tons of money by making a baffle, or utilizing the stock baffles better inside the valvecover so no oil comes with it.
you could put a filter on the valvecover in one or more places and accomplish the same thing. the crankcase pressure will still be relieved at the valvecover. everything else inbetween the vent and valvecover isnt doing anything(especially in an NA motor).

It's about time you provide some details since you seem to know what you are talking about.

If you were to run just a filter, regardless of size, it would become saturated with oil in a small amount of time. Remember this isn't too much of an issue with anything less than 450whp or so. So the tank is needed to catch excess oil and then returns it to the blocks oiling system. This can not be done by using just a filter....
Yes you can run just a filter, but why make a mess.
With the drain back of the catch can, while the motor is not under load, the can will drain back into the block. It's really that simple.

Re: (tepid1)
thanks for expaining tepid.
i think it might be wortwhile for someone to lok into a better internal baffling system, so that you dont have to spend money on all the lines and tanks. that would be just as effective if done properly.
another question:
how much max pressure is the head seeing for FI applications, and then also for NA apps when closed in stock form?
does anyone want to measure?
youd of course need to make sure everything is sealed except for the line running to your gage that youre using.
would be interesting to see, and would allow thoughts on making alternative systems as well.

Re: (dfoxengr)
Sealing the VC to do testing would not be a smart idea. Especially if you are looking for max pressures.
There is a great thread or two about crankcase ventilation. Run a search it's easy to find. The measurements have already been done.
The only problem with modding what's already in the head is the limited amount of space for baffling. Good idea, but I don't think that is the right approach.
A way to help this blowby issue is to gap your rings correctly. That alone will reduce or create more gasses. It's all about finding that sweet spot.

Re: (tepid1)
youd need it sealed up, just as it is in stock form, thats what i meant., basically, if a person already had some setup with 2 holes added to their VC plus the regular stock one on the back, theyd have to seal their 2 added holes, or there would be almost no pressure seen.
cliff notes: set it up like it was stock, then measure.
