Re: PCV mod works!!! Pic inside... (hrdtopv8)
I did the mod Sunday evening. I drove the car to work Monday morning, parked all day and back Monday evening. It had collected about a TABLESPOON of "yet to be identified" liquid. I plan on checking out tonight or tomorrow afternoon when I have some spare time. I noticed a couple of threads where a lot of people have not noticed any oil for a while and then it was only a little. I get this much after the first drive to work. 80% of the drive is highway; 14 miles each way. I wil post some pic's of "the stuff" tonight or tomorrow. I also replaced the PCV valve when I did the mod, just in case. The car actually is running much better since the filter is in place but I have to wonder what is causing that much liquid junk to be recirculated back back through the PCV system which has been ending up in my intake for the past 14k miles ????? :rolleyes:

I did this mod right after installing my new heads and cam, as I wanted to help the car out from the get go. I'll get a picture of the 'milk' and post it later on tonight for all to see.

:( Chocolate milk is not a good sign. That means water is getting mixed in with your oil. If it was fuel, it may have a slight green tint. Hopefully you just had some moisture in the line. If it persists you may have a waterjacket leak into the cylinder and need to replace your headgaskets, unless you know any other way water could have gotten in there, like rain through the intake. Check for steam coming out your exhausts.

Re: PCV mod works!!! Pic inside... (ScreaminDemon)
Good point. In fact, it's a good enough point that I went back and checked my filter again just a minute ago! ;) Anyways, I know what my problem (probably) is. I had a bit of condensation in the filter glass right when I put it on. I distinctly remember that now, and I think that's what I'm seeing in the glass mixing with whatever oil it has captured.
Nonetheless, I have cleaned the glass out and am going to let it dry overnight before I install it again. I'll run some over the next few days and see what I get. I'll keep an eye on the exhaust, as well. Thanks!

I did the mod acouple of weeks ago and I get very little liquid but part of it
looks like oil and part looks like coffee with cream in it. Not sure but I think
I am just drawing condensation. Please let me know how you make out after more miles.

Re: PCV mod works!!! Pic inside... (C5-VERT)
Well, my brother and I installed one of each of these mods on our LS1s (He has a '00 WS6 T/A). We both drover 150 miles back to our place and we found this in the flasks (his car has never had the heads off so it's not from a coolant leak etc as previously postulated regarding AllCammedUp's concern)
Mine had the exact same volume although a little less tan and more whitish foam but mostly water in it. They are installed correctly, too.
We cleaned them out and reinstalled the flasks. We'll see how it goes now.

Re: PCV mod works!!! Pic inside... (C5Noir)
I wouldn't worry about collecting water with the oil. Your crankcase accumulates water too, when it's cooling down, air is drawn into it and ultimately the water condenses in there. When it heats back up, most of the water vaporizes and is pushed out through the PCV valve, back through the engine. That's why they say it's harder on an engine to do a lot of short hops than it is to get it really heated up on a long trip. The water in the crankcase doesn't get to evaporate completely. Then the oil emulsifiers have to take over, shortening oil life.

Re: PCV mod works!!! Pic inside... (bierbelly)
Thanks for the info, bierbelly. This mod would also indicate that I was preventing the water from getting back into the crankcase which would prolong oil life then, correct? A double + for this mod ;)

Interesting, I have never seen any hint of water in mine and its been on there for a couple months now. I would guess it has a lot to with how humid it is and where you park your car. Aluminum changes temp pretty quick and I have pulled aluminum valve covers off in cool/humid weather when the car sat overnight and it was like someone poured a glass of water in there. Used to scare me years ago on the race car when it would sit in the trailer overnight and I would pull the valve covers in the morning to check the valvetrain - got used to it pretty quick though :)

Yeah, it's pretty darn cold here right now, about 25-35*F outside. The very first time I fired it up with the new mod condensation formed IMMEDIATELY in the flask.

Re: PCV mod works!!! Pic inside... (C5Noir)
I park in an attached/heated garage and when I do go somewhere it seldom sits for more then 10-15minutes not running so thats why I never see it.
As long as it goes away after the car warms up, thats why running a 160 thermostat in this weather isnt a good idea, the water usually doesnt start burning off until the oil temp gets above 175 or so..
