Has anyone tried using a coalescing type filter like this one?
http://www.airmaxproducts.com/coalescing_filters.htm
These are specifically designed for removing oil/water in aerosol form (down to 0.3 microns) from compressed air systems.
They are a little pricey though. The above one cost me $105 CDN.

The pcv valve is on the drivers'/firewall side near the corner of the valve cover near throttle and cruise cables. You will see the hose going to the pcv valve almost on the corner. I am doing this today, saw it along time ago and forgot about it.

Edward Lee:
That Craftsman filter you are showing is a general purpose filter. The filter element in that is meant for removal of solid particles and LIQUID water from the airstream. They typically filter down to 5 microns. Most of the water and oil aerosols will pass right through that
The unit I am talking about filters down to 0.3 microns. When used in an air supply system, it is always mounted downstream of the general purpose filter.
They both use similar housings. It is the filter media that makes the difference.
I do not think Craftsman offers a oil separator coalescing-type filter. Most compressor systems do not require them because air tools like lots of oil in the airstream. It is only if you are using the compressed air for painting or sandblasting, that you would want to remove as much oil as possible.

Well, that says it all. Where can I get one of those and what is the drain procedure like? Highly interested.

so earlier in this thread someone commented that when they removed the filter from the regular home depot one they collected twice as much oil???? i just put mine on yesterday and also took the filter out and it is already starting to fill. But eng92 knowledge seems to contradict that stating the filter media makes all the difference. Can someone clarify as it seems the home depot one w/out the filter is just like the cheap ebay hollow canisters that don't collect any oil. Yet only one day and already oil is in there with out filter? which way stops more oil from entering top of engine? I'd say after edwaed lee and eng92 with filter but please clarify. thanks for any help

My earlier post was inquiring whether anyone had tried using a coalescing-type filter. I was not recommending its use.
In a compressed air application, there is no doubt that it provides much superior oil removal capabilities to that of a general purpose filter.
However, our application is different. We are placing the filter under vacuum. The surface area of the filter media is many times that of the x-sectional area of the filter bowl. Therefore an oil soaked filter will more readily give up its oil when subject to vacuum than the liquid oil pooling in the filter bowl.
I am going to give this coalescing filter a try and see how effective it is. I just put new rings in my engine (VQ35) so I am really not expecting much blowby. Only time will tell.

I have noticed one thing. When doing an oil change, I used to religiously fill it with 4.5Qts of oil. Checking the dipstick it was always at the H. My theory is this is too much oil and it's causing the extra blowby.
After taking my catch-can off, I began filling it with 4.0Qts of oil. Checking the dipstick it is right in the middle (may have to add 1/10th of a quart to achieve). No more ping.

Has anybody considered here, that placing a filter where we are could possibly reduce vacuum on the pcv valve? This may explain why people with filters collect less oil, because they are taking more vacuum away from the pcv valve, possibly leaving it shut, or at least closer to shut than say with no catch can. This would also explain the pcv valves gunking up and no longer working on certain people....either way, I see a set up with the catch can and no filter being the wise choice here. Someone should test how much vacuum is being dampened by the filter...

When I had the filter in, I did not collect as much oil as I do now without it. When I removed the filter, it was soaked with oil. It could be that the same way it gets into filter (as vapor), the same way it gets sucked out of it under vacuum and still goes into manifold and a small amount gets collected below in canister...

it would only be logical for the catch can to have more oil in it faster since there is no filter first soaking up the oil and eventually dripping it down into the catch can. Question: wouldnt it still get sucked into the manifold from the filter when it gets vacuumed? i mean like a little bit of it would go in (a very minute quantity). Just wondering.

I have just bought the Home Dept catch can, and I will provide pictures soon. Where the filter goes, I have replaced with a small brass fitting about an inch long to direct the flow of the oil down towards the bottom of the catch can instead of just removing the filter. I think this is a good idea, I will install and report back soon.

You have it backwards. The oil first flows into the reservoir then the air escapes through the filter.
It doesn't flow through the filter then drop into the reservoir.

HUSKY brand "Mini General Purpose Filter" It has 1/4" fittings, there is also a bigger one there, which will work also, but I am unsure as to the fitting sizes. I found this next to the air compressors at Home Depot. Also a plus for the smaller one, price:
$11.97
The model number is not on the outside of the package. Mine was in a tube.
(2x) WATTS brand 3/8" hose (inner hose diameter) to 1/4" threaded adapter (brass fitting)
$1.50 a piece (gotta go to the brass fittings section of HD)
Part #: pb225 or A-293, not sure which one.
looks like: hose <<<((((| filter |))))>>>hose
open that thing up in the store, I did, and make sure these fittings fit.
(I wasn't arrested)
3/8 (inner diameter) fuel line hose from the Auto Parts store. HD did not have this. You need 3 feet on average, this should run you about 3 bucks. I wouldn't settle for any other hose than this classic black hose because gas and oil can eat through most of what HD has.
OK, now, what I did that is special:
I bought a A-715, or pb113 fitting that screws into the inner hole where the filter went on the catch can. It is 1/8" fine threaded and brass, should be in the same section as your hose adapters. Its only about an inch long. I figure this should help direct the oil more towards the bottom of the catch can. I didn't go any longer because I didn't want it getting dipped into any oil already caught.
Price: 89cents looks like this: O)))))))))
So, voila. Grand Total: $19.00
Its installed, looks great, and I'll get pictures when I can. I'll keep in touch on this one.
Good luck!

I can see the big resevoir being more convenient, but is it as effective? I know for a fact it takes more suction to create the same amount of vacuum on the pcv valve if you're sucking through a bigger diameter hose, which of course we can't exactly suck "more". This, IMO could possibly dampen the effects of the bigger resevoir. I'm not bashing the bigger one here, but has anybody compared suction between the two using bigger hose vs. smaller....?

No, but you could always try dremeling the thing, and supergluing a tube, or cut resevoir from another filter to it, effectively extending the bottom, I could see how this would be a wise thing, helping to make it even harder to suck oil out of the bottom of these..... anybody wanna give it a try?

Should the little stone filter come out or stay in???
with it in, oil is still collecting in the tube going back to the intake, so I figured I would take it out, but now it's just two holes at the top of a resivoir???
if I read correctly the oil comes out aspirated in a fine mist, so that mist would just come in one hole and go right back out the other right?

The tube that goes down into the pcv is pretty hard to detach. Can I just take off the end that connects to the manifold and connect that directly to my reservoir? Then I won't have to mess with the end that connects to the PCV.
Ed, some help?

Yes you probably can but you will still need some hose to connect the catch jar to the manifold unless you just slice the stock hose and place the catch jar in line.
However, be reminded that the sotck hose has hard bends in it that lead it to the manifold. If you change the routing or length of the hose, by adding the catch jar, it may look funny or not sit right.
If you really want to get it off, just keep tugging on the hose and jiggling it around a bit because it actually comes off pretty easy. It is held in place by rubber, that's it.
Good Luck!

Campbell Hausfeld mini general purpose filter from Wal-Mart
2 3/8: x 1/4" hose barb and 1 1/2"OD 3/8"ID 55PSI hose from Home Depot
As you can see I just used the stock hose... and only about 3" of the Home Depot hose.
The rubber bands are holding it so that the filter doesnt touch any metal parts.

I like the blue, however, you are going to have a few issues soon. First issue is that the reservoir is small and you will find yourself emptying it almost everyday when you get home. Second issue is that clear hose from Home Depot may not last long. Go and get it replaced with some fuel line hose. It doesn't have to be fuel injection hose, just fuel line hose. Last but not least, those rubber bands will probably last about a month or so under the hood. Use some zip ties in place of them. Otherwise, it looks great.

I ran this setup for few days and had issues with idle. It was like tachometer needle would drop slowly as I released pedal. I took it off was the problem in a vacuum leak? I'm considering it to go back the way trigger has it though. Doesn't shorter hose means less loss in vacuum "suck" power?

I went to Home Depot and asked for fuel line hose and they said they didn't have any... I found a lot of hoses right under where they had their big selection of hose connectors. None of them were for fuel line. Only reason why I got the filter from Wal-Mart was because they said they didnt have it at Home Depot... so much 4 them havin all the answers. Or maybe its just a lame WI thing.

This sounds interesting but can someone translate this for me in English?

I attached a hose from the drain to the bottom of the car and all I have to do to drain the oil is place a small bottle under the car and turn the faucet.

Theres another thread on this topic too, and it contains some more information about about both the hoses and the filters that people are using for their catchcan setups... with pictures.
You might also want to read this post and this post from that thread.

Heh, thx. I've used it for a couple of days and everythings fine. No apparent leaks and not that much oil has gathered... probly because I rarely rev past 3K.

hey guys,
I just got done with doing this mod....
and one question: "which way does the oil flow, is it from the top to the bottom, or is it from the bottom to the top?
i have it hooked up to go from the bottom to the top, and i drove car around for like 5 miles, and everything seems ok....
Can someone help me out on this one please
thank you
