Empty catch can...normal?

[FastSRT19]

Sooooo, i installed Justin's awesome CAI w/ catch can a while back and i love it! :rock: After a few weeks of driving, i opened the drain valve and was surprised how much crap came out and thought "well thats great, it didn't go back into my engine!" So every few weeks for the last 6 months or so i've made it a habit to drain and clean out the can. Yesterday i popped the hood, attached my drain hose to the valve, opened it up and.......nothing, zip, zero. Dry as a bone! I figured maybe it was all gunked up in there which was preventing drainage so I removed the filter from the can's top and looked in :hello: and couldn't see anything so i stuck a straw down in there and it WAS dry as a bone...is this normal? I went from having a bunch of crap come out to nothing :dontknow:

I did check the lines running to the catch can and they were clear of any blockage.

Maybe you are just driving it easier??:dontknow:

Did you change weight of oil??

Are you low on oil? This shouldn't make a difference!

I hardly never get anything out of mine, couple of drops. I do have a long hose running to it, so it amy be running back into the engine??

Thanks for the input! Everything is the same as far as oil level and weight...Maybe the warmer outside temps have something to do with it? Or my O.C.D. is kicking in again

The drain on the catch can is clogged.

He said he took the filter off and did not see any gunk in there at all.

depends on your driving honestly, if you run it hard you will see more condenstation, also the enviroment also plays a big part.

but dont worry bro, if ya got nuttin, means ya doin ok

Put some water in to check and it drained fine...

Thanks Stink! I was thinking the same thing about the weather/temps etc...

I've noticed that as well. Drive 'er easy, and not much will accumulate. Push it, and it fills up faster. Speaking of which, I need to go drain mine. The cool thing about my catch can is a clear tube on the side that shows the fluid level inside.

Ok i feel better now... Yes, the clear tube is a nice touch but mine seems to be a bit cloudy so i cant really see in well :dontknow:

"...if ya got nothin', then you're fine." doesn't really work.

My drain has clogged several times.
Once to the point where the catch can back-flowed (read: exploded through the air filter on top) into the engine bay. Coated everything with a nasty sludge that took forever to clean up.

Don't bother with playing the Neglect card; I check the catch can after every fill-up.

After the first few months, the level viewing tube was very dark brown and unreadable. Justin was cool enough to send me a 2nd one. It's back to dark brown again.

I talked with Justin about using a larger petcock for drainage. He said he'd drill mine larger, re-tap it, and install a slightly larger petcock. A very cool offer, but I don't think it will prevent it from clogging again.

JMB's setup is cool, but I'm going a different route.

If you take the time to read above Kevin, you will see he took the top of the filter off of the catch can, thus look down inside the catch can, and seeing nothing inside. therefore even if the drain was clogged and then competely removed , nothing would come out.
I am sure he is smart enough to make sure he has no kinked lines, or anything keeping the fluid from making it to the catch can.
Even with the boost I run sometimes, if I drive it normal without getting into the throttle, I dont get any residue in the can.
Under normal driving conditions most of the fluid residue will be burnt in the engine and never make it to the can

Must... not... post... something... stupid...

Oh well. F it.

It's not the size of the petcock on your catch can that matters, it's how often you use it.

I feel better now.

BBBBBWWWWWWWAAAAHHHHHHHHAAAAAAAAAAAA!!!!!!!!!!!!!!!:congrats: :congrats: :congrats:

I wonder if there is a DIY writup on that

On a serious note, I've noticed that even with the catch can, I'm getting a fairly consistent layer of fine oil mist on my well-polished engine compartment. With the vac line feeding just ahead of the compressor and the bypass valve open the majority of the time, anything that goes into the compressor comes out through the bypass valve breather.

I considered recirculating the output from the bypass valve to the cold air box, but that would increase IAT's. I might just have to install a fitting in the exhuast and plumb the bypass valve outlet to it. I'm getting a little tired of cleaning my engine bay...

 

[JTS VENOM PERFORMANCE]

Rammy I am thinking of doin a crankase evacuation system, you can find them on summit racings site.
but instead of running a breather line from the valve covers to a catch can, you put an insert into the exhaust, and run the line to there.
this pulls the gass's thru and out the exhaust, and an extra bonus, causes a vaccum in the engine , thus letting the rings seal better. Amvech told me about it, an I have heard from alot of the dirt track guys around here use it and actually get more hp

Yeah, I've had that on my race cars. Kind of a poor-man's vacuum pump.

I'm pulling plenty of vacuum at the air intake ahead of the compressor. I just need an appropriate place to dump the air from the bypass valve. So long as the vacuum created by the exhaust port isn't enough to pull the bypass valve open when it shouldn't be, I'm thinking that's probably a good solution.

Tony- I *did* take the time to read his post.
My post was NOT directed at him, but for others that have the catch can setup. Note the ambiguity and lack of personification in said post.
Not once did I doubt anyone's intelligence (even though I have not faired as well here...).

Mine was clogging with regular "good kid" driving. No racing. The blow-out happened while I was driving back from Boston; cruise control set at 72 most of the way.

I agree with you that weather/climate and driving style can affect the amount of crap caught in the catch can. But with the size of that petcock, the small size of the catch can, and the heat generated by these engines it's very easy for some of that gunk to get ingested, then be cooked and solidify, and subsequently clog the petcock.

Ack! I hate it when my petcock gets a clog!

 

[JTS VENOM PERFORMANCE]

I walk my pet cock

maybe Kevin should and his wouldnt get cloged

Not really interested with what you do with your pet cock. :rock: :rock: :rock:
