Well, i just got all the parts and will install it tommorow, but as i was looking into these online i found that many people pull the filter out? should i do that? also does it matter if i increase the hose length from the PCV to the intake by a decent amount?
Oil Catch for PCV system

And the 3/8ths line i bought is fuel line, does it matter if that touches the intake manifold?
No, won't hurt it.
hey 2002 maxima if you could do me a huge favor and post a pic of your set up, im trying to figure out the best way to mount it and where.
Thanks
Thanks
This is the oil it caught from only 300 miles of highway driving (no hard acceleration).

Hello everyone. I have been looking for a way to give back to the community, so I will be doing (hopefully) a test to see which method works best for seperating the oil from the crankcase air and for the lowest cost. I will be getting one of those Condensators, and I will also be using a compressor air/oil seperator rigged up for auto use.
Any questions or suggestions?
Post em here or pm me.

Thank you 2k2 maxima
i bought the separator from campbell hausfeld at wal mart just like the one showed it the site above....one site demonstrates with the filter in and the other says remove the filter..i tried it both ways and got better gas milege without the filter..in fact i just want to separate the oil vapor and you would not believe the oil condensation at the bottom of the jar.just imagine this stuff goes into your intake without this seperator...prior to this my intake and line and pcv valve showed no oil at all
I think they are both pressurized due to the blower. They both catch of oil, and my intercooler is now oil-free inside.
Neither goes into the intake manifold. I capped that port and terminate both filters at the blower inlet.
There is an additional function of the PCV system that you need to be aware of before you try this solution (besides the environmental issue). The vacuum applied through the PCV system into the crankcase provides some negative pressure on the rings to help them seat. I don’t know how big of an issue this is, but it is certainly something to be aware of.
This thread has got me thinking, though. I’m thinking of installing one of these oil separator catch cans myself, just to see how much oil is going down my intake track.
I feel the PCV system's constant purge of crankcase vapors has a strong effect on the life of the engine. I feel that there is far more condensation of water and unburned fuel in an open draft system into the oil with an open draft setup.
I feel that this has at least as much value as the environmental aspects, and far more value to the average person.

Someone may have already addressed this issue, but I think the single most important aspect of the pcv system is the fact that the engine builds up tremendous pressure within itself, and because of this, there must not be any restriction at all to the gases trying to exit via the pcv valve. If the gases do build up, the greatest problem is gasket blow out.

Well, regardless if it is suction or pressure, from what I have seen on the homemade oil seperators, the one thing that seems apparent is that they get clogged up rather quickly, which is indicated by the oil cannister not continuing to fill up which. The unit should always be working until the point where the cannister is so filled up that you need to empty it.
With the homemade oil seperator, all liquid, solids and gases have to go through the filter before continuing on to the engine. If this filter gets clogged, the pcv system flow is either severely reduced or stopped completely. What happens next is a build up of pressure inside the engine, and this will cause gasket blowout or piston/cylinder sealing issues as well as possibly leaking at the valves.

PS. To answer the pressure/suction question, both pressure and suction work together to ventilate the gases and the check valve prevents them from returning to the engine. The biggest question though is how to maintain flow through the seperator without always needing to change the filter. I believe the filter that most are using on the Campbell Hausfeld units are filtering too small of particles, and that the filter needs to be one that filters a larger micron size, ie instead of a 1 micron particle, maybe move to a filter that goes only as low as 3 or even 10 microns. You don't really need to filter this oil, just seperate it from the gases. Another option would be to drill minute holes through various places on the filter element. Small is the key word here, as you want the vapor to continue as a vapor so as not to mess up the process by which the unit works.

so if i understand this then if i take the filter off which some people do the vapor comes in at high speed into the catch can hits the baffle the breaks up the oily vapors falls to the bottom of the can then the air continues oil free? no restriction when you remove the filter.
That's a negatory there Boxcar. If you remove the filter completely, the vapor will go through so fast, it won't have a chance to drop the oil in the cannister. Sure, a little will, but you will lose most of the benefits.
I wonder whether the hole should be drilled in the bottom of the filter houseing or in the filter itself?
I drilled holes in the filter for my wife Forester XT and still caught a good bit of fluid (intake tube was clean).
