if you want to "vent" your crankcase, install an oil catch can! it actually serves a purpose, and looks better than a stupid filer attached to your valve cover. the main reason i would not vent it, is because IT DOES GET MESSY!!!!!!! if you want oil blowing all over your engine compartment, go for it, but i would highly steer away from it, and just install a catch can

Where can I get one?

I think it's more like where can't you get one. They are universal and avaliable just about everywhere. One of the nicer one's that I've seen is the Greddy one found here:
Ptuning has them: http://www.ptuning.com/html/search-r...l=model&Brand=

Dezod has them: http://www.dezod.com/cat_oil_catch.cfm

Hope that helps. And of course if you're into making your own there are DIY articles just google "oil catch can" or something to that effect.

80$ for this one!!!

Mr_Meaty

if it's just for mess, i'm not worried about it, as my hose points down. but I was told that it was actually bad for the engine.

Here is my question, (cleanliness and environment aside) what is SAFER for my turbo/motor:
Just leaving the crankcase vented with nothing on it? Or routing it into the intake pipe with NO catch can?

20tCDude05

Well, if it goes into your intake pipe, will it go into your turbo? Plus, that GReddy catch can looks sick. Do you like have to empty it once in awhile?

Mr_Meaty

Yes and Yes.
that's what the catch can is for...it catches the oil blowby, keeping it out of your intake and your turbo. You DO have to empty it out, but we don't get that much, and I'm pretty sure anyone who has had one has not had to empty it yet after over a year or so!

t_urbo_C_harged

Leaving it open I believe... If you had a bung welded on your intake pipe and fed that hose to it without a catch can, the intake would then suck the oil vapors in and would be more of a risk of your engine knocking/detonating. The reason it would do that is the oil fumes lower the octane rating, thus making it unsafe for a turbo setup unless you run a catch can... I would recommend either moroso or the DC3...

so if you left it open it would be better, your engine bay would just be a little messier... hey meaty, why not get a catch can then maybe running the output side to the vacuum block.... wouldn't that have the same effect as routing it back to the valve cover??? To me that would be a better, more cost effective solution than what you were saying earlier in the thread.

Mr_Meaty

i dont' have any more ports on my vac block, but wouldnt' taht be to much vacume for the valve cover?

Joe_Dezod

You do not want your vacuum line connected to the valve cover. Oil vapors would get into your BOV, wastegate, boost gauge and other devices. This could make a very sticky mess, causing things to stop functioning properly.

Mr_Meaty

I swear I posted that in my post as well....anyway...
but what about the rest of t_urbo_C_harged response? Which is safer? Open or to the intake with no catch can?

Joe_Dezod

He's right about going directly to the intake with no catch can lower your effective octane rating of your fuel, which increases the chance of knock.

The best overall solution that addresses more problems than anything else, would be having a catch can in line with the hose going from your valve cover to the intake pipe. This addresses basically everything.

Mr_Meaty

Oh...OK...but dont' your turbo kits have the valve cover connected to the intake pipe?
Why would you have it set up that way if it lowers octane and increase knock?

i was thinking that too phil.. i was just looking at ryans the other day thinking about this thread. haha

Mr_Meaty

Does he have a dezod kit with that tube there an no catch can? What do you have on yours? A filter? Just open?

TurboToyotas

The best solution is a catch can.......

Which I will be offering a kit. Valve cover/2 bungs with the fittings and steel braided lines and the ventilated catch can

But if you cannot do a catch can......leave it open.......and save for a catch can

Regards-

Todd

PS- a cheap filter will work in the mean time, just clean it....but recirc is a bad idea[/quote]

java09

Phil, ryan has a dezod kit. no catch can. and mine is jsut open.. i eventually will get a catch can!

todd, since you will be offering a catch can i will get it from you!!

t_urbo_C_harged

x2

I understand what you are saying and thought about it after I posted it... I guess the best way would be to get a vented catch can, or any catch can and just have the output open or something...

Mr_Meaty

Well...if you ahve the output open, it's really not better then a filter...if you rout the other end into the intake, the incoming air helps create a vacuum in the valve cover to help pull the blow by into the catch can.

Right now, I just have my old tube pointing down.

java09

i have no tube on mine just open! not much oil though.. none at all really...
