Default Can anybody fill an oil catch can in 2 weeks - I can

So...I rerouted all my oil catch can hoses 12 days ago. I emptied my catch can and cleaned it all up (see here)

So...it's been cold again (below and way below freezing) and my catch can is full with water already.

Anybody else have this problem? The concensus is that it's water condensing in the really cold catch can, so if it still does it in the warmer weather, i'll be more concerned than I already am.

Water: condensation
Coolant: Ruh-roh

When you say it is "full", are you talking like a pint, or a small amount like you showed in the other post?

In many cases during cold weather, I would find my vacuum pump tank (not on a WRX, of course) with a bit of "latte" in it...It doesn't mean you're ready for a tear-down. Smell it: does it smell like your coolant? If not, don't sweat it as long as your engine levels/parameters do not change.

When I say full, I mean my catch can is full. Like 16 ounces.

It is latte and does not even remotely smell like coolant. If you condensed exhaust into liquid form, this would be it.

Just throwing out some thoughts:

It sounds (smells) like blowby, but you haven't stated you were using oil...are you? Have you looked into the intercooler for signs of oil? If not, maybe ask one of the turbo gurus if it could be a seal. I think HndaTch627 or AZscooby might be of help...

If it's doesn't smell like coolant, and you're not using any oil, I would be inclined to recheck the fashion in which you've integrated the catch can....I think there have been some issues with install location. If the aforementioned factors were covered, I wouldn't sweat it too much. HTH

Default Hope it's nothing serious...

Don,

Just wanted to check in and give you some support. I'll be installing my catch can soon and read your posts with interest.

Hopefully this is just a subzero temp issue....however, the first time you had much less "froth" no??? Has anything else changed modification wise since your first froth incident. Also, do you think this has anything to do with your mysterious hesitation problems of recent past?

Your car reminds me of some of my old girlfriends.....drama
good luck

Cheers - Flames

P.S. I wanted to add that, I've heard that even a slight overfill of oil, can cause significantly more blow by....I do not know it this is true....are you overfilling maybe?

You need a compression test.

I have been gathering the exact same substance in my Greddy catch can as well.

I have been using oil... and it seems my coolant may be dropping as well.

The last compression test I did was less than a month ago (Jan 19) and I was holding the exact same compression I was holding back October 30.... so thats the last 3 months I have had no compression degradation.

Basically I get: 148, 150, 150, 140. The 140 being the driverside-rear cylinder.... basically what Subaru deems the most prone to knock based on the knock sensor location... and I have apparantly confirmed this .

No this latte stuff has been getting worse... BUT, I get no exhaust smoke AT ALL. I can fill my catch can in about the same time as you.

BUT, the car is pulling every bit as good as it has been... if not better since Ive installed the Utec (Mid-Jan).

To me, the fluid almost smells like pure gasoline... but of course doesn't look like it. What I plan to do is get an engine block tester (one that tests for hydro-carbons in the radiator) to see if perhaps my headgasket is going.

I also need to get a leak-down test... which is much more indicative to the health of your motor.

This all pretty much sucks... but at least she's still running....

The one thing that really confuses me is that I am not smoking, at all. Is this because I have no cats? (ie- not burning off the oil)

I only get smoke when my catch can plugs up with ice or I pinched the lines to the catch can.

Other than those two times, I had no smoke at all.

It means a lot. The filling up we are talking about is water condensing in the can because it is really cold.

When it was warmer, I never had anything....

why don't you get another can, or make one and put it on the valve covers only. then you can figure out where this stuff is coming from if it is really blow by or whatever. make this can out of something else. i made one out of 2 inch PVC pipe for about 15 bucks. i have not put it in yet cause i don;t have any hoses yet.

Excellent idea... even easier however would be to extent the use of clear hosing.

The Greddy kit comes with clear hosing, its only fault, not enough.

But good 'ol Home Depot comes through and carries pretty much the exact same stuff (clear tubing reinforced internally with a loosely woven nylon mesh). So I bought an additional 10 feet or so (@0.99 per foot I think).

Anyway, I only used it where I needed it.... however if I were to just replace all the breather hoses/pipes with this stuff... there should be quite a trail of goo visible through the hose from the culprit location.

At least if its a head gasket, I'll know which one...
