Well, I was contemplating getting the Lingenfelter Air/Oil seperator but saw someone selling a used Provent 200 for only $60 shipped. I looked at the highly detailed PDF: PROVENT 200 PDF

I found that not only was the Provent 200 identical to the one that Lingenfelter was selling but it was ~$25 cheaper (BTW, the cheapest I have seen the PROVENT 200 go for brand new is $129 w/o shipping).

Here is a pic of the Lingenfelter one:

If you go back to the PDF on the PROVENT 200 do you see a difference. Yeah, me neither.

Not sure if this separator is too large for my tastes in the engine bay but we will see.

Looks like a nice unit. I might have to pick one up at some point!

If I remember, I will bring mine w/ me to the meet next monday for you to see. Bigger than it looks in the picture.

What exactly does this accomplish?

Get a lot of use out of that phrase, do you?

Bryan: Separates the oil from the air in your vacuum hoses. Pretty nice if you have lot's of blow-by.

Hmmm is it any different than a catch can?

Catch can's catch the oil and store it.... this separates and returns the oil

Actually, one hopes that it catches it and stores it...most time it doesn't get all of it and some still gets by but it does make a difference vs. not having anything at all. I recommend at least having a catch can on your turbo engine. The PROVENT 200 is just a little more sophisticated catch can that does a better job at collecting the oil vapor and gives you the ability to return the collected oil.

So? I was just explaining a point more for someone that doesn't understand exactly what is going on w/ it...but thanks for that.

lol, my favorite part: The title tells you all you need to know!

I was pointing out the fact that your explanation also applies to catch cans.

I also think that the words "more sophisticated" and "one hopes that it (works)" don't necessarily sway the uninitiated when used in the same parag.

And I also thought that Julian made the same point in fewer words.

That's all, no biggie.

Here, have a rolleyes yourself.

Sure. If it was no biggie why would you reply then? And then post saying "Words, words, a lot of words" is like saying "yeah, yeah, blah, blah, blah".

I was just trying to state that the standard catch can doesn't come w/ some form of collecting medium so basically the vapor goes in from one hose, swirls around in a box like area and then goes out another hose...so you would hope that it would collect/catch the vapor. Julian was stating that it would catch the oil (implying that all oil vapor traveling through would be caught which is false)...and everyone that knows catch cans and how they work would know that but a newcomer to the catch can wouldn't. That is what I was trying to emphasis so he would better understand it.

I apologize to all for trying to help a fellow member better understand something by expanding on a general explanation and in the future I will make sure that never happens again. Geez.

And if someone wants to get on me about getting slightly peeved on this. Don't b/c everyone else does the same thing. And I am not upset anymore b/c I said my peace. And, yes, I am still tired and sick.

No need to be so defensive man. Seriously. Relax.

*writes notes* Hmm... very interesting.

Holy sh*t no need to be dicks, I just asked what exactly it was used for. I see the title Julian thanks, but it doesn't tell me where it goes or why someone would want one

Posted: **Sun Jan 13, 2008 6:22 pm**

My reply wasn't meant to be dickish Brian. It was a simple reply, that is all.

dammit. i'm late to the innarweb fight!

Ever seen recirculated oil in a catch can? You really want to put that back in the engine?
Do you pee in a filter and recycle that?

Posted: **Mon Mar 24, 2008 11:21 am**

ArFab has just built a recirculating air/oil separator. They are in the last phases of engineering it and it should go into production soon

Posted: **Mon Mar 24, 2008 7:54 pm**

Sorry to jump in late on this, but I have a genuine question. Both serious explanations and Julian's explanations are welcome.

Like Tallen says, do you really want oil that contains HC and CO recirculating? What they taught us at school is that car oil has become cleaner thanks to efficient removal of blowby gases. It seems counter to my armchair engineer logic that oil, that has been blasted by said gases if passing through this filter, is placed back in the system.

Furthermore, it seems like the amount of oil returned would be negligible, and that where you are wasting oil is really just in the lubrication of the cylinder walls.

The Mann-Hummel website mentions needing to conform to stricter oil separation legislation of Euro 4. Does anyone have readily available information on the numbers that Euro 4 expects? I wasn't aware that we were monitoring the burning rate of oil.

TEACH ME!

there are turbo cars running around with hundreds of thousands of miles on them that don't have catch cans. they seem to be doing OK.

I would only worry about a catch can (separator, whatever...) if I had a very large aftermarket turbo running much higher boost then stock.
