Purpose of a PCV delete?

[M-Hood]

mine also doesnt leave much oil, so rerouting it in front of my tires would probably be just a slippery if I ran over a slug trail lol

if you want to save money on oil, just reroute the PCV directly into oil fill cap

How exactly are you measuring the amount of oil that is coming out of your breather hose if you are just dumping it to the ground?

Most people that run a catch can post that they have to empty it out every once in a while because it does fill up.

[skemems]

Same point I was making earlier, its impossible to have a performance oriented car and be a tree hugger.

Tell me about your HP gains without your PCV? or how about getting a HFC instead of a test pipe or deleting your cat? lol... just sayin..

I dont measure it, and im sure nobody else running a ground dump does either. my oil consumption is the same, and I dont leave any stains on the ground

[BaseDrifter]

but no one ever preaches to people who take out their cats adding more air pollution...

Well, some of us would, but why bother? This is one of the reasons I run a HFC and not a test pipe. Also, performance differences are negligible and it doesn't smell like shit now.

no pace car, but my oil consumption hasnt changed, plus ic I rev the shit out of it wil cardboard under the dump, you see nothing

I'm no master of PCV systems, but if you have removed the source of vacuum to the PCV system then the vapor is only getting pushed out while under boost, which you won't see any of while sitting still.

hence dumping pcv or running an OCC

The reason I mentioned that at all was because you said "if you want to save money on oil, just reroute the PCV directly into oil fill cap."

the little oil that does mange to escape, is negligible

I noticed you didn't reply to my point about dumping oil and road safety for others on the road, is that negligible?

so let me get this clear. you guys are green peace when I say dump to ground, but you guys have no problem burning it out the exhaust.

so in other words you are saying, please dont dump your pollution on the ground, dump them in the air.

If I had to choose between you dumping your oil on the roads or having it burned off, yes, I would choose having it burned off. In fact, that is exactly what the stock system does, albeit within the combustion chamber instead of the exhaust system.

The fact of the matter is that owning and driving any vehicle introduces more pollutants and poses more externalities on society than not owning a car would. That is exacerbated when trying to increase the performance of the vehicle. There are certain aspects of pollution that are unavoidable and others that can be avoided, I try to avoid them whenever I can.

Same point I was making earlier, its impossible to have a performance oriented car and be a tree hugger.

Not impossible, but there is some "bargaining" taking place for sure. I care about the environment, I also like working on my car. Unfortunately performance electric vehicles powered by renewable energy sources are way beyond my price range/non existent, so I make due with what I can for now. As I said earlier, there are forms of pollution that are unavoidable, choosing to dump your PCV to the ground is definitely avoidable.

I dont measure it, and im sure nobody else running a ground dump does either. my oil consumption is the same, and I dont leave any stains on the ground

Keep rationalizing it. Also, replying within the quote as you did before makes it really difficult to quote you back, just FYI.

[ray4624]

If you seriously think that the oil coming out of the pcv is enough to cause a danger to other drivers then I am at a loss for words.

you are the one rationalizing here.

You(specifically) can avoid the pollution you are so concerned about. You own an internal combustion engine, most likely more than one, in which you were not forced to buy. They sell electric cars, pedal bikes, roller blades, skate boards, comfortable walking shoes, etc., but let me guess, you justify your "unavoidable" pollution by saying(fill in the blank).

i would love to hear it.

Take 100% of the oem pvc system and toss it:

- Plug up hole in induction boot
- Buy 034 Motorsport or Integrated Engineering block breather adapter, 1' of hose and a vented catch can, good location for catch can is right above drivers side frame rail behind driver side headlight, or on false raintray to the left of the coolant reservior.

If you have a vented vc buy another 1'-2' of line and run to catch can too.

or: just dump to ground from block breather adapter with hose

[Mad Cow]

Thank you lm0812, finally a voice of reason. I personally don't give two shits about environmental stuff but these things are here for good reason. Why spend time reinventing the wheel when you already have a perfectly good example sitting right in front of you that already works better and will last longer than anything you'll cobble together in your garage? If the stock system burns oil vapours, why the hell would you go through all the effort to route a hacked-together PCV system through the exhaust to burn it? And I don't want to smell oil vapour as I sit in traffic, this is a goddamn Audi not some prehistoric carbureted pushrod motor-powered beast, there's a level of refinement expected from a modern car and oil vapours coming through the vents doesn't align with it. Apparently the consensus here is it doesn't matter if your car's making all sorts of nasty smells and/or dripping oil because the stock PCv system is "crap", and I put that in quotes because it works perfectly damn fine so long as it's not clogged or broken. Why would you care about a bit of oil in your induction system? Do you pull it apart so often that getting your hands a bit more oily is such a huge issue to you?

Damn I feel like an old geezer yelling at teenagers to turn down their loud music sometimes. This whole contrarian attitude to engineering choices is insane, apparently every possible alternative that's not stock is better than everything stock just because it's not stock. This attitude is rampant on every single automotive forum I've been on and it needs to die out already.

Also, nobody addressed the oil pressure issue with having an open crankcase. Anyone wanna step up to the plate?

What does stains on the ground where the car sits with the engine off have to do with how much oil you are dumping on the ground while you are driving?

Also, nobody addressed the oil pressure issue with having an open crankcase. Anyone wanna step up to the plate?

What oil pressure issue would that be? I have been running a vented catch can for years and push my car to 8500+ rpm and don't have any oil pressure issues.

There can be a increase oil pressure issue if the breather setup does not allow enough pressure out of the block.


The stock PCV setup is for emissions only and decreases the amount of power the engine can actually make.

[GrapeBandit]

I dont recall saying my engine was off. earlier in the thread I stated that if I put a towel or piece of cardboard under the dump, and rev the shit out of it, creating boost, theres nothing there.

also, my oil consumption is normal, so im not concerned.

[BaseDrifter]

Wait, I'm the one rationalizing? I'm not the one saying that dumping to the ground causes an insignificant amount of oil to be deposited. Your reasoning is that since you haven't measured it and no one else has, and since you don't get much blow-by while revving it in neutral (where you won't build any boost), that it is not a problem. Ask Mike Hood if the drag strip would let a car make a pass with a PCV system that dumps to the ground.

If you want to make the argument that the oil your car drops on the ground is insignificant in the grand scheme of global (or even domestic) pollution of both the air and water supply, that's totally fine. What you're doing is insignificant, the difference is that it can be easily avoided.

If you want to make the argument that the oil you're dumping is very unlikely to cause an accident, that's totally fine. It is very unlikely to cause an accident. But can you eliminate that risk by not dumping to the ground? Absolutely.

Now you're saying I shouldn't own a car because I don't see the need to run a test pipe and dump oil? I justify my unavoidable pollution because I love cars, I love my car, I love working on my car, I love driving, I love having the freedom to come and go where I please when I please, and it's hard to go on a nice date when you tell a girl to meet you at the bus stop.

My tailpipe emissions are unavoidable. But you know what would make them worse? A test pipe. You know what would give me nearly the same power increase while still helping to mitigate the pollutants I put into the atmosphere? A HFC. Great, I run one. You know what is an avoidable form of pollution? Dumping your PCV system to the ground.

If your car doesnt see any boost while reving the shit out of it, you need to check out your problem. im not mike hood, and im not going to a strip, so thats irrelevant

so your love of cars, and worring about going on a date with a chick gives you justification to pollute. I guess in your mind that trumps pollution. like I said, keep rationalizing, reasoning, justifying, or whatever you want to call your reason to pollute. you have your reasons, and I have mine. difference between us two is that im not the pot calling the kettle black.

My tailpipe emissions are unavoidable. But you know what would make them worse? A test pipe. You know what would give me nearly the same power increase while still helping to mitigate the pollutants I put into the atmosphere? A HFC. Great, I run one. You know what is an avoidable form of pollution? Dumping your PCV system to the ground.
Your tailpipe emmisions are avoidable. dont use internal combustion engine. theres many other ways of transportation, just stop trying to justify your polluton, you can completely stop at any given time

I don't want to get into this earth-saving argument but your car does NOT make boost when revving. At most you will make maybe ~5psi (Honestly I don't even think it's possible to get out of vacuum without load) but you would really have to rev the shit out of it for that.

thanks for joining the argument! greatly appreciated.

your statement of not making boost than saying ill see 5psi is a contradiction. last time I checked, anything to the right past zero is boost.

EDIT: just to answer thread title. the reason for a pcv delete is to keep the crap from recirculating back into the engine.

[RENOxDECEPTION]

Can we make some points without pointing fingers? This whole thread has an angry tone about it. I want to learn something new about the PCV not read pointless drama.

[pbcrazy]

Your welcome!!
You would not make enough boost to significately impact the pcv system. I said 5psi as a guess but like I mentioned, I don't think you would make any boost (at all) revving.

stop thinking and start knowing.

all seriousness, pcv is nothing good for the car, maybe the environment. the proper way to delete it is running a CC with a vacuum line connected to it.

You can run straight dump to ground, or an e-scavenger too with no ill effects. maybe the only problem you will encounter is green peace on the forums.

At Mad Cow,

What is all this OEM superiority about? And what is all the "hacked together pvc system" talk?

You're inventing wording out of thin air, since when is plastic superior to 300psi professional braided line and JEGS -AN fittings?

Hacked, what's hacked?

Good grief, cobbled together in your garage? Since when is the most expensive best quality line and fittings used on the most expensive built cars in the world cobbled?


You're not even forced induction, you're 2.8, come one man.


YOU ARE COMPLETELY OVER LOOKING THE OEM SYSTEM IN INSUFFICIENT FOR INCREASED TURBOS AND SOFTWARE. I do not understand what you do not understand. The oem system is for OEM cars, end of story, people on the forums are not driving oem cars.


There is no smells, there is no dripping oil, there is no hacks, there is no ghetto, I do not understand what you do not understand. You are naturally aspirated.

There can be a increase oil pressure issue if the breather setup does not allow enough pressure out of the block.

You'll only lose a couple psi worst case scenario, but that could make all the difference at hot idle. Not really a problem for you, but for all those people who idle for hours in traffic it can't be good. This is with an open crankcase though, a catch can would probably provide enough resistance to keep the pressure inside the crankcase in check.

My main point is catch cans and pcv deletes aren't for everyone; if you're making big power on a track then no problem I respect that, but if you're daily driving a mostly stock car then there's absolutely no reason to go about tearing out every piece of emissions equipment "just because".

@A1 A2: Read my sig again, see where it says ex-2.8 now 1.8t? I've been driving and tinkering with a 1.8t for a while now. I had the chance to toss the whole pcv system but I decided against it because I like to keep things looking stock and don't want to bother messing with a system that already works perfectly fine. And since when does the motor in the car I currently drive change the validity of my statements anyway? Most people here have mostly stock cars, the minority are making big power. OP has a stock (or mostly stock) car so whatever applies to people making 400+whp doesn't necessarily apply to him.

I couldnt even bother to respond to mad cows post. everything he said is completely wrong and I didnt want to write a composition in rebuddle.

the pcv system is for emissions only.

the pcv system is for emissions only.

its not even the fact that its prone to failure, it recirculates all that crap/soot/vapor/oil/debris back into the intake tract.

has any of you guys ever saw what comes out of a catch can?
I tell you its not something I want back into an engine that I give 2 shits about.

the reason is not "just because". theres a just reason to rip the shit out, that is if you care about your engine.

I have a very nasty pic of the contents of a catch can of mine, I understand it's all oil in the end, but it is thee worst stuff I've ever seen.....I would not want to reintroduce that stuff. I also remember my fmic and fmic piping pre-catch can..what a mess!

That's a moot point when you consider the timeframe over which this happens, by the same logic you shouldn't drink tap water because fluoride is a dangerous chemical. Sure you'll die if you drink a glass of fluoride-saturated water, but trace amounts are perfectly fine. How many hours of running does it take to accumulate 10ml of oil in a catch can? Spread that 10ml out over that time and you're looking at imperceptible amounts. It might pool up in your intercooler, but what does that harm? Show me a study that conclusively proves that the oil vapour introduced by a pcv system is detrimental to engine life, until then it's just speculation and theory.

[A1 A2 German]

But we are not talking about the accumulation of 10ml in a catch can, we are talking much more then that when using a pvc system, why?

We are talking about more oil consumed or drawn as the induction boot is a vacuum and draws on the pvc system. A pvc system uses more oil, a catch can just catches small trace amounts of vapor air that gets pushed out. When I say a pvc system uses more oil, it's due the to fact of the positive pressure pushing out oil/oil vapor with the addition of a draw under a vacuum of the induction boot.

It's

push

vs

push + pull

The PVC is push + pull. But, we are talking more then keeping a FMIC clean, with I do not need a study or 2000 word essay to need to justify my want. And not worried about or saying an oem PVC will hurt an engine, saying I want a cleaner engine and my engine to breath better under heaveir stressed vs oem 180hp.

Why don't you start "knowing" as you obviously have no clue how load on an engine effects a turbo making boost.
I'm sorry but If you are making more than 5psi in nuetral I would love to see a video, especially if you are off the stock hairdryer (k03). There are not enough gas and they are not moving fast enough to see anymore than 5psi in nuetral, and like I said I wouldn't see a bit of boost in nuetral with my frankenturbo (not that I'm stupid enough to rev my engine to death)

uhmm, actually the oil will coat everything on its way back into the engine. it will develop in theboost hoses, I/C, intake manifold & intake valves.
on the other side of these valves is where the combustion is taking place. the temperatures in there is so hot this is what actually causes the oil carbon to form on the valves.
oil baked on your valves can cause loss in fuel economy, loss in power, pre-ignition, and knocking.

back to what oil in tbe I/C is going to harm... the oil passing through it can actually coat the cooling fins lowering the efficiency to cool the air.

for an engine to be the most efficient you want fuel and air ONLY….any oil in will hinder the explosion resulting in less power.

but then again, this is all just speculation

[A1 A2 German]

Ding ding ding

I used to pull my intake manifold and Seafoam the piss outta the valves, as well, looked like the inside of a motor (kinda a joke as motors look dirty).....I no longer have to do that since a catch can. The valves always look good now.

Perhaps I should have phrased my original reply better, that is my bad. You will not see anywhere close to the amount of boost in nuetral compared to when the engine is under load (obviously). Therefore, revving the engine would not be accurate representation of how much oil you dump on the road. And besides, for those of you running a vented catch can or open crankcase, there isn't near as much vaccuum being applied to the crap oil which means that some of the nasty oil you keep bringing up will never leave your crankcase (I would rather have to seafoam my engine every 50,000 miles than have that crap left in my crankcase)

I recommend against that too. but we will leave that for another thread. this one already got sidetracked for a while with all the green peace folk earlier.

but then again, this is all just speculation

It is speculation until you get some hard evidence that the trace amounts of oil introduced by the pcv actually measurably affects engine life and performance. I agree that massive amounts of oil vapor is bad, but I'm saying a small amount doesn't appreciably affect anything. Dirty intake valves from oil vapor are only a problem with with direct injection engines because they don't have fuel washing them down every combustion cycle.

The world's not black and white, everything is shade of gray. All your arguments are based on this black or white, right or wrong view. It's not like that at all.

[GrapeBandit]

It is speculation until you get some hard evidence that the trace amounts of oil introduced by the pcv actually measurably affects engine life and performance.

I just explained it above. Have you ever heard anyone saying their oil catch can is filled with speculation? Of course not. that would sound silly. Its filled with gunky oil, fuel, debris, water/condensation.

It is speculation until you get some hard evidence that the trace amounts of oil introduced by the pcv actually measurably affects engine life and performance.

since there is "no hard evidence" and its only "trace amounts of oil", you should have no problem dumping this in your oil filler cap then.




^after one week

Dirty intake valves from oil vapor are only a problem with with direct injection engines because they don't have fuel washing them down every combustion cycle.

Not only, it just occurs more frequent in direct injection engines like the FSI.also, the carbon buildup it not just limited to the valves, it build up on spark plugs, piston tops, and the combustion chambers.

Have you never seen carbon buildup on a non-direct injection engine before

It can not hurt to delete the stock pcv and keep any and all crap from getting back into the engine. The cleaner, the better.

[Mad Cow]

You're not understanding my point at all. I've seen what catch cans catch, it looks scary but that doesn't mean it's bad for the motor to burn this stuff up through the pcv system. Water in the oil evaporates when the engine's warm, likewise with gasoline, warm up the catch can to above the boiling point of water and it'll be almost pure oil in there, much like what you'd find in your oil pan. I also find it funny how the creator of those first 2 pictures says it's a chemical reaction between oil and water vapour, by that logic mixing sugar into tea is a chemical reaction too.

As for carbon buildup, a little bit never hurt anything. Again you're using your black and white logic here, a ton of carbon is bad news, a little bit is whatever. Motors are dirty things, you'll go insane trying to keep everything sparkling clean inside and out. To me it's not worth it, I see that to you it is, but that doesn't mean everyone shares your view, nor does it mean everyone shares mine.

I think this thread has run its course and that enough info has been provided for a 3rd party to make a decision themselves as to whether or not they should rip out their pcv system, if anyone else has anything to add feel free, more information is always better.

[GrapeBandit]

Wrong, and wrong.
Nothing gets burned through the pcv system. A pcv system recirculates crank gasses, oil, fuel, debris or what have you back into the intake system.

It is bad for the engine to burn this stuff off for various reasons said in the thread. you only want air & fuel in the combustion chamber, oil is no good.

I also find it funny how the creator of those first 2 pictures says it's a chemical reaction between oil and water vapour, by that logic mixing sugar into tea is a chemical reaction too.

you missed the point. the pics were merely to show the crap that goes back into the intake tract while running stock pcv.

As for carbon buildup, a little bit never hurt anything. Again you're using your black and white logic here, a ton of carbon is bad news, a little bit is whatever.

wrong.
any carbon buildup is no good, even if only a little bit. where do you think a ton of carbon buildup comes from it doesnt happen overnight, it builds up over time! guess what?! little by little

seems to me that you are the one using black and white logic here.
