Emptied my catch can after 9 months!

[airbornerifleman]

I recently started hearing a bubbling/drumming sound coming from my intake, while idling. Initially, I thought it was the rear PCV hose (turbo breather hose) check valve flapping around. I soon realized that the rear PCV for my VIN does not have a check valve. After empting my CC, the sound went away.



Here's what came out.

9 months??! Did you forget to empty it haha. Thats a lot of crap you got there. In the colder months, you are going to accumlate more water

[DoThisMyWay]

yuck.

[Cottonmouth]

I should check mine. It has been a while.

[Hugh@EuropaParts]

I run a hose from the bottom of my catch can down to the ground so it just empties as it fills up if that makes any sense...

[schirm]

Does that mean you just dump that crap to the street. Kinda messed up.

But you wont let it ever overfill.

You can still empty it. It seems like a safety measure in case you forget.

i just have a couple hoses running out under my car with no catch can. thats 9 months of stuff right there and its mostly water which will evaporate. that amount of oil residue spread over 9 months and im guessing ~15k miles(assuming avg 20k mi per year) is not going to be noticeable on the ground. what do you do with that nasty oil and water after you empty the catch can? they dont let you pour water in at your local oil recycle place. throw it in the trash? it ends up in the ground anyway.

if you were really concerned about the environment you would burn it in the engine like the factory intended and let the catalytic converter clean the exhaust. im not calling you out on not having a cat because neither do I....just putting it into perspective.

i bought a valve from a local hydraulic shop and ill be able to just reach below the can turn the valve open and it will drain down below car. likely into wherever im draining oil when i do oilchanges.... just a thought the valve cost me less then 5 bucks the threads matched to the threads on the bottom of CC only thing im concerned with is the larger substance that accumulates. after a few oil changes ill likely have to remove the can and dump it. hydraulics shop said everything should follow gravity when valve is opened and not to worry.

That a great idea, but I want to avoid any leaks be it air or oil, plus taking 15 mins every 4-9 months is not that bad.

lol no I did't forget. I installed it in the summer and there was barely any accumulation, but like you said the colder temps makes more condensation so realistically its only been accumulating for 4 months.

Makes since Hubert, but my setup is recirculating (one of the CC port is routed to the rear PCV hose). If run a hose from the CC drain plug and the CC is empty, I might run the risk of sucking unfiltered, un-metered air through that hose to the engine via the rear PCV.

Thanks for bringing this up. I forgot about emptying my can.

Emptied it. Yuck.

looks like my mud butt

I never ran a CC so I just assumed it was straight oil, I did not know it was mostly water. My B

When I had my MK5 GTI i was constantly emptying my CC, after a year and a half I had an entire 2L bottle full of garbage. For those that live in areas that can get very cold keep a very close eye on your CC. One morning I was on my way to work (the night before hitting roughly -25 degrees celcius) I stopped at a light and all of a sudden smoke started pouring out from under the hood, I immediately pulled off the road and shut it down. Had the car flat bedded to VW to diagnose, only to find out that my catch can froze and it built up so much pressure that it burst a few seals in the engine because the pressure had no where to go. The dealer then replaced all broken seals and installed a new PCV valve and told me to run that in the winter and switch back to the CC for spring/summer/fall.

After seeing how much is "caught" per day in the catch can I came to the conclusion that just dumping it wouldn't make much of a difference, it has literally been a few drops a day... even in the winter where there is a lot more deposited.

[TFSI]

I feel like the hose is too narrow that it doesn't drop enough when there are oil/water in the can. If I get some time after weather gets warmer, I'll try to change the hose to bigger size. Let that drain as soon as it collects in the can.

It doesn't accumulate as quick as ppl think, even in cold temps.

So just dumping it on the street? Wow [facepalm]

Do u know how much oil average cars drop on the road? My jeep used to leak diff oil, transfer case oil and engine oil... It had 60k miles on it.

If you think that is bad, you are clueless.

And so if others, you can too? In Quebec, the police/firemen can fine you if they see your car leaking any environmentally harmful chemicals and that is the right approach. Forces the driver to fix the issue or pay big fine.

There is a difference between a drop or two of oil here and there, and loosing a quart of oil at a stop light. If it takes 9 months of driving to fill that container, it would be a almost be an unnoticeable amount dripping.

This... it's literally a drop or two per day in the winter. I'm as environmentally friendly as the next environmentalist (check me out in the picture below) but a drop or two of oil a day really isn't going to make a difference.

Hugh and Capt. Planet are still bids to this day!!!

[event]

Lol, um people oil come from the earth, big whoop dropping some of it back to her. This isn't gallons in the ocean, it's a few drops on pavement and shit that will be burnt up by the sun or tire friction and a mess of other stuff... most of what they are dumping is water anyway...

Also, some of you people complaining. You better not have or ever get a HFC or test pipe, cause you are a bunch of hypocrites if you do...

[edit]
Oh wait, looking at the first to complain had a test pipe. You're a fucking idiot...

[Stewy]

I just drain mine every time I do an oil change...easy to remember.

You have SGT1 and quattrro, you’re burning more fuel/oil than a FWD stock B7. Who is more environmentally friendly in this case?
If you cared about the environment that much, you would not be driving an Audi!

Most of the contents of the bottles is just water, the tan color stuff is actual oil. If you live in a building with parking, just check some of the oil leak puddles some other cars are making. They leak more oil in one year that my CC will catch its entire life.

Its not about what's happening. Its about what you know you are doing that you know can be prevented. I Dump my catch can and send it with my old oil.

Exactly, it is not difficult.

Seriously? Where the hell do you think it goes after you empty your CC? You "sending it" does not mean it goes away, but it becomes someone else’s problem. How do you know they are doing the right thing? Have you looked into the company standards? Procedures? Regulations? It does not make you any better, just makes you less of an asshole than us. I dump mine at the car wash every 5k km's

[your daddy]

dump mine once a week when i wash the car. got rid of the awful petcock, and put an on/off ballvalve. hose to ground. mostly water. and to those who dump in their oil, most places burn waste oil. and that is a nono in there.
