Default Ebay catch can installed on 06 STI

while back i bought a cheap catch can off ebay thinking any kind of catch can will do. but as i installed it, it didn't catch any oil. so i read that putting foam in the can will help but the catch can i had only had a drain hole and no way of opening it up to put some foam in there. so i bought another catch an off ebay but this time i bought the one that you could unbolt the top and bottom ends and put some foam. let me tell you the quality is WAY better then the fist one i bought. the only thing was that i had to make the bracket to mount on the strut tower as the original bracket bolt holes does not match the holes on the strut tower. i haven't driven my car enought yet too see if it will catch any oil or not but here are some pic.

u will recieve little oil if anything, esp more so as the life of your car ages over time. a can is a can in my book, i dont see how it can go wrong, how much did you pay for it?

Looks alright, although it won't work very well if you do get oil going into it.
The purpose of a catch can is to collect hot oil vapors, allowing them to cool and settle. With it mounted above the turbo, you're keeping the catch can heated, which in turn is not allowing the oil to cool and settle.
Therefore, when the intake pulls vacuum through the can (if you have it set up properly) it's just gonna pull the oil vapors back through and into the intake...

Unless you have a tube sticking down through the can into the foam that would force the oil to travel through the foam at the bottom, the setup is rather useless.

Sorry if I'm putting this a bit harsh, but I don't know how else to say it.

Beautiful car, anyhow man. Just be thankful you don't have much blowby yet

the foam is all the way up on top of the catch can and it should go through the foam before it exit the catch can. i know its not the best place to put the can but it was the easiest place.

lol, yeah there ain't a ton of room in those engine bays...
Definetely a nice, clean install, and with the foam at the top it should work fine!
(i'd make a small heatshield for it)

interesting... wonder how well it will actually work.

may i suggest some more attractive tubing - maybe even clear?
I bet Tygon makes some that would look a tad cleaner.

LOL. A magnetic drain plug?
If you have metallic shavings making their way through your PCV system you need more than just a Catch Can!!!!

Thanks for the link 2006STI! I think I'll pick one up for my $hitbox...
A heat shield is a VERY good idea.
Especially with the scoop directing a portion of it's forced air straight to that general area
I'm sure you have a long list, too... I would.


alphakry: It should work just fine. I had a GReddy that is the same basic idea and that worked fine. Catch can functionality is all in the installation and routing. It's a very simple device.
What I would do is get rid of that sight tube and put a vac fitting in the top hole, then run that to a vacuum source and use both top fittings for PCV hoses.

Make sure the foam you put in there is resistant to high temps. You don't want boiling hot oil to hit the foam and catch on fire.

hmmm.. i'll have to do my research. Not quite sure what a mod like this really does and why anyone would want it in a brand new 06'!

after about 20 min of city driving, i check to see how hot the catch can and i didn't get very hot. just a little warm and i think the the hood scoop direct enough air to keep it and the turbo cool. so heat should not be a factor. i'm not sure the foam i put in there is heat resistant or not. need to find out.

I don't buy the whole cooling of oil vapors.
As long as the vapors are hitting the media in the can (a stainless steel scouring pad works well) they are going to get trapped and not come out of the can.........its a physical thing not a cooling process.

alphakry: There is no benefits NOW. But as the engine ages and it starts to spit oil through the tubes, all of that gross oil vapor won't find it's way into the intake system, and through the intercooler. It's a very good idea to start now.

Farnsrocket: Look it up. Its the cooling process that makes it work.

No benefits now?! As it ages?!
zerofighter, you are spewing out a lot of bad info.

Sorry to bump from forever ago, I was just browsing through my old posts.
Bad info? Sorry, but a catch can is a simple device. There shouldn't be any blowby on a brand new car. Therefore, it's of no actual benefit, but as the rings wear in a bit more, and the car starts to show some typical and completely normal symptoms of a little blowby, as in oil in the pcv tract, then the catch can becomes beneficial.
I understand how the PCV system works, and the proper way to set up a catch can.
Proof? the pcv system catches oil vapors. The oil is being carried in a gaseous state almost, therefore, if you have the can set up at a hot place, like next to the turbo, the hot can will keep the oil vapor just that. A vapor. Some type of filter media in the can is definitely a solution for this, but placing the can in a cool area with some filter media is a much better idea.
Sorry if my advice was displayed as misinformation, as I know it isn't.

also, again sorry for the 4 month bump...
