Why don't more people run oil catch cans?
Why don't more people run oil catch cans? You know, the can that collects oil vapors that would normaly go back into your intake stream.
Supposidly you can safely run 3 more psi w/o detonation. However the way I look at it, you can run what you run now, that much safer.
Either way why dont more people run these? For a reason, or because they don't know about it?

I think because Im too much of a cheap skate. I think I will eventually build my own, rather than spend the huge price tag greddy has on them.

Re: Why don't more people run oil catch cans? (Arturbo)
Huge price tag?! HA!
I'm doing mine for under $80. All you need is the Moroso Dry Sump Breather Tank (works as a catch can) - which is 65 from summit racing - and like $15 in little accessories.
If you want to read more about it go to http://www.theoldone.com and do a search in the forum.

Re: Why don't more people run oil catch cans? (00SilverLS)
Just wanted to add this review I found also:
All I can say about this product is "wow". I never had a clue that an engine could throw out more waste from the crank case and recycle it back into the engine. With this can, and I've only had it installed for about a month, I'd honestly say that I've drained about half of a L. of fluids out of my enigne. If your a turbo owner, than this little catch can idea/mod will not only run your system cleaner, but it'll decrease the intake charge from your system allowing for less pinging, detonation, and overall will net you a few extra PSI of boost. If your still N/A as I am at the moment, you'll still pull out a ton of just extra deposits from your crank case that you never would have thought possible. I was blowing a lot of white smoke out of my tail pipe, but now the can has reduced the amount conciderably! When I drained it last night (Sunday, 1/7/01) I had found that I had traces of Gas coming out of the head due to bad compression. Believe me, the catch could possibly put an end to many future engine problems; you may suprise yourself. - Dustin Palmer

Yeah, Moroso is an American version of Greddy. In other words, SEVENTY FIVE BUCKS FOR A PLASTIC BOTTLE!!!! If I were going to spend that much, I'd pay an extra 20 and get the Greddy. I don't believe the Moroso is baffled either.

Actually you would be wrong. The Moroso can is aluminum and is the only one that I know of that's baffled.
This topic comes up maybe once every three months. Spouting TOO wisdom is nice, but 3psi is some kind of theoretical number that doesn't really mean anything. For $80.00 it's an okay mod.
Don't use that clear line. It took about 3 days for that line to collapse on me from the vacuum. I went to Home Depot and got some clear reinforced 3/8" tubing which took about 2 weeks to collapse. Get the strongest stuff you can, or just use 3/8" fuel line.
These guys talk about it more here: Do a search... http://www.hostboard.com/cgi-bin/for...pics&number=40

Supposedly the vacuum actually sucking at the PCV hose helps to clear out crud and is more useful. Otherwise it's a legality issue as well. It's illegal in most areas to run an open PCV system.

So does GReedy or Morroso make this to where all you have to do is put it on instead of fabracate something?

Re: Why don't more people run oil catch cans? (00SilverLS)
Hmm, this is all very interesting but tell me this. Under boost, the PCV valve is closed, there is no oil or oil vapor getting into the combustion chambers. So how can putting an EXTRA catch can (car already has one) between the PCV and the stock catch can allow you to run more boost? I agree is may keep your combustion chamber cleaner under vac when the PCV valve is open, but under boost it is completely closed.

Re: Why don't more people run oil catch cans? (VaporTrail)
You sure about this? Every one I've seen has still gone to the intake manifold. I even talked to Larry and he said so too. (Maybe I'm wrong though 
)

Re: Why don't more people run oil catch cans? (00SilverLS)
So you keep the 2 things separate?
The PCV->catch can->manifold
and
valve cover->small filter->intake pre turbo?

Re: Why don't more people run oil catch cans? (VaporTrail)
Vaportrail, you are talking about the breather, not the PCV valve. there is no area that sees only vacuum and not boost. there is no vacuum inside the intake tube of the turbo, it is open to the atmosphere.

GOD, do you think that you can create 20 oz/in of vac by facing a tube in another direction? NO, That is how much vac is being pulled out of the crankcase at idle, the breather is an inlet, plain and simple. **** SLASH CUTS!!! I'm done explaining, this is starting to **** me off. PCV is not a hard concept to understand.
