i have one installed. i got it for 5 bucks so i just decided to install it. i have it hooked up to the valve covers. i took off the hose that connects them and put both hoses to each one.

 

would you be able to take a picture of yoursetup?

 

I bought one of the greddy knock-off 19.99 ones. I had to disassemble the all the pieces after a couple of vac leaks, and reseal it all with rtv sealant because hte gaskets are crrraappp. It's fine now.

 

edit please delete

 

Who wants to take a pic and show us how they did their's???.... Raise their hand :3_confuse

 

Air/water separator for $12 at your local Home Depot. (Not Lowe's- they don't carry anything useful.)

I'll have pics in a few mins... gotta upload them.

 

It will F* up with boost homie :3_chubby:

(if you mean this)

 

No for F/I

 

good pics of oil catch can line routes...

Good find....Just gotta find something pretty cheap....Hoping not to spend more than 50 bux for a can

 

i got one of mine off of ebay and one from greddy so i am probably pretty qualified to talk about the quality on both. u cant beat the greddy. that thing is solid. the ebay ones have a higher possibility to leak air and leak oil.

search my name and for oil catch and u will see a thread w/ tons of pix on how to properly install it and what hose sizes to buy.







edit --- haha that was another thread i posted in w/ the same response "search my name" hehehe

 

why can't i use this FI?

 

who said u cant? u can.

however, the pcv valve on the tibby is craaaaaaap and if it clogs ur gonna be in some trouble w/ those pressures f/i. it is better to take it out, put a pipe thread pass through in there and drag tube the thing.

 

i bought one of ebay for $17, all u have to do is to put some aircompresor white tape on things that bolt in and maybe silicon where you see gaskets, and u will probobly need hoses from autozone... but it was defenetly worth it

 

yes... front top right of ur front valve cover is a black 12mm hex tube w/ a hose connected to it which goes to ur intake manifold. pcv basics 101 man. if u want a catch can, u gotta know what you are bypassing. u simply take out the black thing.... aka the pcv valve, put in a 3/8npt fitting pipe to barb fitting (dont quote me on size, i think that is it), shove on a new bigger hose, and point it down towards the ground so it is the lowest thing in ur engine bay..... kinda like it is "dragging" on the ground. drag tube. so when the pressure gets high in ur crank case, now it will vent to atmosphere and any oil that gets out will just drip on the ground.

 

Alright guys but i don't want to vent to atmosphere. I want to create a setup where i can reuse the oil (especially since i'm F/I and i'll be venting off more of it.) That way i just empty the tube right back into the oil tank. Also dragging it on the ground is messy as all hell.

I'll let you know what i do today and show you pictures... maybe you guys can make some suggestions.

 

^^ Thats why lol

 

Paul your sig is teh winz

 

lmao i agree.

come on brian what's the answer?

 

Yeah but I just mean what is going to suck the air out? Won't I get a constant low PCV pressure CEL?

Wouldn't it be better to install something like a ball-and spring boost controller to let the pressure out after the catch can for when I'm making boost? I'm just concerned about sucking out the pressure... and don't most people run catch cans with their F/I?

 

And by ball and spring I mean something that would normally go right through and be sucked by the IM, but when there's positive pressure on it, it would release to atmosphere. Wouldn't be too hard to fab up.

 

uhh... there is no monitoring of the pressure in the crank case so no, u wont get any form of cel. and you are thinking sucking out pressure, i am talkin about blowing out pressure. same difference. if there is a hole, the pressure will escape. u ever see old motors? they simply have valve cover breathers. a little filter on the top of each. old school cars didnt have pcv valves conneted to intake manifolds. that is an emissons thing in new gen cars. like most emission things, cars run better w/o them.

 

okey dokey so.... my catch can is worthless? dang it!

 

u can certainly use it. just plug the hose into one side of the can and drag tube the other. this way the oil doesnt hit the ground.

 

Ok ok.

And right now I have both front and rear ones goign to the atch can. Is this correct? I only see the front one on a lot of people's setups. I T'd the rear tube that normally goes to the stock intake elbow so it's going to the catch can too. Is this correct?

 

Ok I just read some stuff and ideally, you'd put it in the intake BEFORE the turbo, correct? That way it's still sucking the crankcase even under boost, but now you put a catch can in that hose, and oil doesn't coat your intercooler. Ahhhh it all makes sense now.

 

Hey bud, when I had that can I vented the crankcase to it and the other end I just ran a drag line. You will always have a little pressure in the crankcase to keep things moving through the can, so you don't need vac. At idle if you cap off your drag line for a few seconds and then open it you will get a woosh of air from pressure buildup, so you know the case is being vented.

 

a catch on the rear is not necissary. i had the baffles removed on my vavle covers and still it spit just a very very verrrrrrrry little amount of oil into the catch can in nearly 10K miles.


bottom line paul, you want that pcv valve OUT in an f/i application. the stock one is not sufficient enough to vent the crank case pressure quick enough.

 

Ok thanks guys just a few more q's.

The valve is just that hex thing right before the nozzle on the top right of the cover, right? And I can just unscrew it?

And don't I want to move the rear hose somewhere because even if it doesn't need to go through the catch, it should be dragging instead of pressurized, right?

And since I don't really feel like dragging the lines, and I already ahve everything installed, would it be best to just put a mini filter on the other side of the catch can? And keeping the rear cover goign to the catch can wouldn't hurt anything would it? Is there a valve or not on the rear as well?
