Yes, an oil catch can would help with some oil issues, but it's not critical for a Fit especially if it's a daily driver.

 

I cant really see the 2nd hose you guys are talking about I see the coolant one next to it and another behind it that leads to where the power steering is at

 

Take a closer look at the valve cover. Just to be clear, the valve cover is under the intake plenum. Once you've located the valve cover, to its right side you'll see a hose that will lead to the two metal pipe joined together. One is for the coolant that goes to the TB and one where the said valve cover hose is connected to. IIRC, it's almost right below the TB.

 

Don't mean to thread jack my fellow country man's thread, but since this is about catch cans, I might as well address my q's in here.

DSM,

granted that there is PSID diff. between the valve cover and the crank case thus you suggesting that there should be dedicated lines for the valve cover and the crank case, but wouldn't that be negated as they are both going into the same catch can and there would only be one return line to the intake tract?

 

Exactly because both of them empty in to the can and this helps neutralize it, so when the can is pressurized it escapes through the one way valve and then to the intake. Because on an NA, even at WOT when there is no vacuum the positive pressure will still look for the path of least resistance.

Since there is positive pressure relative to atmosphere in the head and/or crank case, but 0psi/0 in. HG at WOT or actual vacuum any other time, it is pulled into the intake.

You don't want them tee-d for the same reason when people stand up to fast they can get dizzy or "grey out" and that is because there is a drop in pressure in an adjoining vessel the blood will rush back down instead of flowing up to the brain.

 

I see.

Thank you for your usual enlightening posts.

 

I am just glad I could help.. and you guys were asking about catchcans?

Hows this one from JM Fab?

 

^those are nice... ARC makes specific applications too.

I'll be good with a universal can

 

DiamondStarMonsters...
Hey man, gotta give it up to ya'... 90% of the times I read your posts I haven't the slightest idea what yur talk'n 'bout but you say it so eloquently that I find myself look'n for yur posts jus' to see how dumb I am when it comes to the "technical" aspects of our rides...
Keep it up man!!! Awesome.

 

what size of nozzle are those on the catch can? 9mm or 12mm

 

they are 9mm and the catch can is the T1R carbon fiber universal



by the way check out this catch can I think it would look great along with your future intake. To bad I didn't find it before i ordered my t1r

 

^ thanks
that look really nice... same finish as my KICS lugs

I think I'll go with a CF catch can to match the intake. Either Simota or this ebay-Universal seller confirmed that it has wire mesh inside.

 

here's mine

 

LOL that cf can looks exactly like the t1r

 

is that a T fitting?

 

Yup looks like a barbed t-fitting!

 

hey at least they look good.

 

Is this a catch can showoff? JK!
I use mine because of oil buildup in my pipes. I used to hook it up to the intake pipe for my turbo but it would literally suck the oil out of the catch can and into the turbo and pipes. I'd check my intercooler and can have well over a pint of oil in there. Now I just run the catch can with an open end.

 

Please share pics of your catch can! A whole pint of oil is a lot.. you might need bigger lines or a bigger check valve... Did you have fittings welded to your valve cover or are you using the stock fittings?

Have you ever hot tanked your IC to clean all the gunk out?

You mentioned that you are venting your can to atmosphere.. Is there at least a filter of some form?

Otherwise you will pull whatever is blowing around under the hood into the engine under vacuum.. dust, leaves, etc.

But based on your build and all of your posts that I have come across, I would imagine you are already aware of this...

If so please disregard this last portion of my post. I am genuinely curious about the first couple questions either way

 

so you're sayin it's fine to run a splitter into the catch can? where is that other line from?
