Normally compressor air pressure holds the valve on these shut, they kinda auto drain when everything is off.

No spring means the drain certainly opens in vaccum though.

hmm, interesting about the drain, thanks. haven't even opened the packing on mine yet.
I could just replace the whole valve thingie with a threaded plug or something though, right?

<p>Kind of, except the hole isn't threaded.</p><p>Once you pull it apart you will see, there are 2 pieces to the drain, and they have an o-ring to seal them.</p>

<p>Waiting to see how you modify the drain before buying one for myself.</p>

<br />1 track session.
I've used a HUSKY one for years on another car, between PCV and IM. The specs are similar except for the 40vs5 microns, though I didn't see a problem with that.

Found the same one hi_im_sean posted, decided to give it a try. Under 100 miles of use:



Painted it black just because.



For the drain, I used two rubber washers to hold it shut and a vacuum cap on top of it all. It's been maybe 300+ miles now with no leaks-- I'll see how it goes when I remove the cap. Remove the original drain and it's just a hole. I left it as is to have the O rings in place.

I also saw one with the exact specs at HF for $6.99.

I see a lot of vented catch can setups with both sides of the VC incorporated into it. Reading on PCV systems, my understanding was that the PCV side is an outlet only and that the exhaust side is both in and out depending on vacuum/load. I put the can between the exhaust tube and intake and got some WOT runs in (to close up PCV) but the can was bone dry so I decided against an open system.

Did you see a difference in how much you were collecting?

correct. If you have the stock baffle setup, its important you keep it this way. If not, the drivers side will fill up as it has no internal drain and start spewing out the port. I couldnt wrap my had around how it all worked until I found the following post by hammer

The exhaust side vent system has two chambers, it vents blow by gasses in an na engine near full throttle and on a boosted engine whenever there is boost.
Air and oil enters the center chamber and most of the oil is separated and drained back in to the head, all the blow by and some of the oil however makes its way from the top of the center chamber to the bottom of the second chamber where it pools near the back of the chamber (oposite side from the vent port you see outside the valve cover, remember you are on the trottle and there are some g's and engine angle sending the oil away from the vent opening and the transfer tube between chambers enters the second chamber close to the camber floor so oil will hit it and slide toards the back of the engine)
When you get off the gass and on the brakes the pcv valve creates low pressure in the cranckase/valvetrain area and the oil moves toards the front of the seccond chamber where it is sucked up the port where it came from, and it drains back in the center chamber where it is drained back in your engine where it belongs.
This is important, in order for this vent to work you need a SEALED seccond chamber AND a vacuum source (the pcv in this case) without either one the oil that got past the center chamber separator will simply come out the exhaust side vent and there is nothing that you can do about it but to modify the system and do your own r&d to get it right.
You probanly will need a vented catch can on the exhaust vent on a boosted or na engine that spends much of its life at boost or full throttle or has exesive blow by.

The pcv side consist of a single chamber oil separator/vent, in most cases the separator handles the oil well since it only vents past the pcv valve on light or clossed throttle BUT it does let some oil through when you close the throttle at redline or high rpm and boost, under tose conditione some of the oil does get past the seprator and into the im.
This is bad because that oil will lower the octane of the mixture on your next wot run and cause random detonation at high rpm whenever it gets ingested.
To prevent this from hapening I and others have installed a non vented (non vented mishimoto) catch can between the im and valve cover, you do need a pcv valve either on the line between the catch can and im (that is what i preffer) or between the valve cover and carch can (that is what i have).
Good luck and you all can wake up now, i am done.

With the HUSKY unit in the other car, which was a daily driven track car, I didn't really have to empty it often-- it was easy access but it was a FWD layout so it isn't as open of an engine bay. I'd check it about every oil change and it'd fill up halfway, up to the filter bottom.

Eventually I noticed it would stop filling up after a certain point. I am currently leaving the "PrimeFit" unit until it stops filling to see if it does the same thing.

I placed the catch can between breather tube to intake and did several WOTs runs but it had no trace of oil vapor. After the same amount of time between the PCV and IM, you can tell there was vapor in the tank. I did this to confirm if oil does come out of this tube since I found conflicting info-- if it did, I may have ran them both to a vented can and ignored that the PCV needs vac.

<p>When you get the amazon catch can will you measure the hole at the bottom. And the top. I wonder if I could just swap my bowl with the valve to the other filter.</p><p>Also just realized I mounted this where I wanted to mount my afpr. *** me.</p>

<p>I also need the depth of the drain hole. So distance from the lip of the hole inside the bowl, to lip outside of the bowl.</p>

That's meant to be .389 and .321, right?

Sounds like a M10x1.5?
