Oil Catch Can Install?

[b-morr]

I have this one http://www.extremepsi.com/store/cust...cat=731&page=1

I was wondering, do I just connect the breather hose from the valve cover to one of the top nipples on the can, then my hose to my intake to the bottom side nipple. And then plug the other top nipple on the can and I'm good to go? I'm not eliminating my PCV.

Thanks,
Brian

I think the inline ~$2 does the job quite well.
not bad looking either... could paint the white part red...hmmm

I got that pipe at O'Reilly Auto Parts...Part #25249 'Flex Hose'. It was $9.99. Good peice and it gets the job done. The clamps that go around it can also be purchased there, Part # 5520V. Hope this helps

So what exactly does this 'check valve' look like? Is it like the inline filter thing 3 posts ago?

The person I got my greddy catch can from was running the return tube on the can with just a filter on the end and not hooking it back up to the intake. right?

Find the nipple off the valve cover. Install catch can in between that and the intake manifold. Done.

No problem man. + rep for me!! haha I wish.

But my car sucks so stop lyin'

If I remember the hose you want to tap is right near the coil pack. I used to have a n/t. Car was so fun. Good luck!

I have the same catch can. what are those two 90 degree elbows for on the side of the can?? I am planning on removing my vaccum lines to the taboo speed shop "race only" setup. I was going to simply follow that diagram and leave the egr valve, but after reading this im more confused than before.....

Not to sound like a noob but can someone please state the correct way for installing ONE oil catch can.

im looking at the taboo speed shop and it says to put the catch can between the PCV and the nipple on the left side of the valve cover. It doesnt say nothing about no check valve or how tsiboosted is running his setup.


Now from reading all this im under the impression that FOR ONE CATCH CAN::::: from the can, one line back to the PCV. With the other going from the can to the nipple on the left side of the valve cover with a "Check Valve" in the middle......
Can someone please let me know if this is correct?? If wrong, please correctly correct me.
sorry for being kinda rude i just want to have a clear understanding, thanks!!

I thought I understood the process for installing 1 sealed catch can and now I'm totally confused. Can anyone kindly clear this one up with a diagram (maybe from paint) so it will be the end all be all for a SINGLE SEALED CATCH CAN setup.

Before you guys start bashing, I already read the 10 page thread on the "stupid PCV". I have excessive crankcase pressure which blows out the oil pan seal. I did seal it with RTV gray seal too. I told that a "proper" oil catch can setup can eliminate this excessive pressure. Here is the link of the catch can that I recently bought. I was told that a 3rd fitting needs to be attached to the catch can and the rest of the instructions was up in the air. I really want to get rid of this stupid oil leak.

The best way (how I did it) is: pull the pcv from the valve cover, clean it, mount it into the catch can and run a hose from the intake mani to the pcv vakve. Then screw in a 1/8" barbed fitting into the valve cover and run a hose from that to the other fitting on the can. Make sure nothing leaks and the line from the IM to pcv are clamped. Check the hose from the intake pipe to the left end of the valve cover, make sure it's clean and leak free. Also make sure it's not restricted cause when you boost the crankcase pressure (blow-by) will flow through it into the intake pipe. With good flow you should be able to keep the crankcase pressure low enough to prevent oil leakage.

 

[dsmcurse]

yes there is in deed blow by. no matter how good a shape of engine you have if you start makin power you will have crankcase pressure. this presure releases through the valve cover. the stock set up is fine but start moddin and it is no longer adequate. the best thing you can do (in my opinion) is eliminate the pcv all together. first you got think the pcv just blows crap cantaminated air into the intake manni. do you really want this. i know i only want fresh cool as possible air goin into my intake manni. so plug that off. eliminate it all together. next the other breather vent that is on side of valve cover next to your cam angle sensor. eliminate that as well. that little piss tube cant breathe off the crank case pressure plus look where it goes. into your air filter tube thats connected to your turbo. agin i dont want my turbo to inhale dirty oil air. just completley eliminate both stock breathers. next your gonna take the oil baffle plate off from inside the valve cover. when you have it off look inside. youll see tiny little spot type welds that hold this oil baffle plate on. drill those tiny welds out and remove the plate. now you get 2 90degree 5/8" hose barb fittings and put them in the top of your valve cover. your gonna have to drill pretty decent sized holes in the top of you cover. try and make these holes just barley smaller than your hose barb fittings so that you can force them in there kinda snug. i put a tiny bit of jb weld on mine when i did this. i did it very clean tho. you cant see any jb crap. i put both of mine on the cas side one above intake and one above exhaust cam. after this you have to put the oil baffle plate back in. you can either try and duplicate how the factory did this with there tiny spot weld techniuqe. or you can pop rivit it back into on. i pop rivited my. every pop rivit got a drop of silicone at the head of it for double leak proof insurance. mine turned out totally clean man. look at my profile for pics. the one pic dont have any hose on it yet cause i took a pic when my engine wasnt all the way put together but you can totally see what i mean by the pic. send me a private message if you have any questions and ill go out to the shop and take a more detailed pic to send you. the next thing about this is the catch can itself. your gonna have 5/8"hose barbs goin into it with a nice fatty k&n style breather filter. like the ones the v8 guys put directly on there valve covers. have a clever little on/off valve drain device to bleed the oil outa the can. if you mount this on the fire wall your car will stink. the fumes will go into the cabin and you will smell the dirty crankcase air in your car. best place to mount your catch can(in my opinion) is in front of motor behind the passanger side head light. right next to the water over flow can. there you have it. a functional system that will properley releive all the crankcase pressure and it will look good. use to 5/8 ones dude. the lil piss tube 5/16 hose dont work. trust me there will still be alot of pressure in the system puttin tons a stress on all your important engine seals.

I have installed multiple pos catch cans exactly like the one you bought ( no offense ) as well as some high quality catch cans. The way yours operates is one tube is from the intake manifold and one hose goes to the catch can. This is a terrible setup for a turbo car.

Good catch cans will have bigger tubes or lines, as well as a chamber with a vent and filter on it. The key thing is it doesn't add to the issue of a leak, as it's always open to atmosphere. Yet again a good catch can will have baffles inside and possibly steel mesh to catch the hot oil mist. The baffles and mesh catch the oil so it wont escape into the engine bay.


You could always just put a 3' tube on that pcv and run it behind the tranny =)

 

[Mobile_DSM]

Dude, a catch can is no big matter. Simply REMOVE the PCV from the valve cover. If you have access to an old stock 1G IM, there is a nipple on it that can be remove and used in place of the old PCV on the valve cover. If you dont have one use a barb fitting as stated above. Run rubber hoses from the two outlets on the valve cover to the catch can. BTW, the catch can you listed here has no filter, which it needs to release air. It is better to get a can that is baffled which works like a air/oil seperater. AMS sells one made by ALLSTAR that is made like Im talking about.

 

[dsmcurse]

key to doin this right is hose diameter. the factory 5/16 dont work! plain and simple. you need 1/2" or perferably 5/8". and yes the steel mesh inside is the way to go. yes it needs a fatty k&n style breather filter. yes pcv is stupid! recycle the crap dirty oil air to you intake mannifold? why from a performance point of veiw. fine for stock and emmisions. recycling that crankcase air into the intakemanni just burns it in the cumbustion chamber. thats fine for a means of controlling emmisions. but screw that, it hinders performance. let that dirty hot oil air vent to the atmosphere. like i said mount the can by the coolant over flow. that way the fumes breathing out will have a chance to kinda escape out the sides of the hood and what not. mounting directly on fire wall and you will smell this dirty crankcase air in your car bad. trust me

im not totally sure about this but im like 90% sure that under super hard load like redline at full boost when the crankcase breather off of the valve cover is really breathing out the air and then you let off the gas it turns to vacume. just for a sec. my own personal beleife is that if you ran straight hose (no catch can) that when you let off the gas and the crankcase breathing hose turns to vacume it could suck. if you ran straight hose behind the tranny and pointed it at the ground you could risk suckin up debris. not sure about that but i think its plossible

 

[crimsondragon]

Before you use that ebay catch can, I suggest you fill it up with water to make sure it doesn't leak.

If you still dont get it, heres a pic of mine.

thats sweet man. very nice. take notes boys. thats how you do it! notice the pcv is gone? there is no crap air blowin into the intake manni. notice how the other breather doesnt go to air filter tube? its cause this guy is smart and doesnt want his turbo to inhale dirty ass oil air. looks very clean. let me ask you this tho. with the can being on the fire wall do you smell the crank case air in your car? i woulda mounted by the overflow and got a shiny metal coolant over flow tank and had matching tanks side by side to look mean as hell. but dude, seriously that is wicked sick hats off to you bro
