Greddy Oil Catch Tank

Is it purley cosmetic? I ve talked to a few people and i cant decide what id does, and wheather it has any benifets or not? for 89 Bucks is it worth it?:help

Is the greddy one cosemetic? Yes, because its polished and shinney, and looks very nice under the engine bay, and you could actually use a pop bottle to do the same thing. But the idea of a catch tanks isn't for cosemetic reason's. It catches blow by, so u should have less burnt oil coming out of your exhuast..... I had one on my car. I thought it was worth it, and the greddy unit looks real nice, especially if you replace the rubber hoses, with some nice earls ss braided lines, and some earls fittings. Nice dress up for 50 bucks in lines.

Can't figure out what it does?

This is straight from the link you posted.

Avoid crank case blowby contaminating your intercooler pipings and intake manifold by installing the Greddy catch tank, to separate the crankcase pressure vapor.

Do you think im really stupid enough to not of read that :rolleyes

Anyways bp2ooo

Thats exacally what i wanted to know, thanks man

If you look at a lot of the more tuned cars, most of them will run some sort of catch-can system. There was a big thread about it a while back, I think 240Z Twin Turbo posted it or was a big part of it or something.

Basically, when putting down bigger numbers, it's better to promote flow from the crankcase through the intake stream than just venting the crankcase. I don't recall the exact reasoning though. Do a search, it should answer your question better than I can .

i know it aint greddy but i do recall summit racing selling a catch can, although for the life of me i cant seem to find it on their site. maybe yall can have better luck than me (long day at work)

Hey thanks guys for the help, bte, i dont wana sound like an extreme n00b but where do the hoses tap into?

[BuudWeizErr]

The in line will come from the T on the valve cover and the out will go to the intake tubing before the turbo.

OK, this is just a thought that went through my head.

Has anyone seen the new apex'i advertisement about their turbos? It mentions that there is a much higher tolerance with the compressor blades to the compressor housing. It says that since there is less space in between the blades and the housing, there is less air being beaten around, and therefore more efficiency.

Now since there is already extremely low clearance between the stock blade/housing, wouldn't a little oil in there help out? Kind of like bad piston rings will seal better (if only momentarily) when you put a few drops of oil down the spark plug hole.

Also, I would imagine that things would tend to stay a little more lubed and sealed with some oil (such as the throttle butterfly).

Just a fleeting thought that I decided to share.

Besides, whats wrong with burning a little oil? Hell, 2-strokes do it all day long.

[charlotte240]

aaawww c'mon guys. At least let me know why I'm wrong because that actually made a little sense to me. I mean, I know that there has to be SOME reason for a catch tank (other than engine dress up).

[xyster]

charlotte240, I could be wrong, but here's my opinion...

the things you mentioned (piston rings) are designed to seal. impeller vanes are not designed to seal with the housing; the housing is there simply to direct the flow produced by the impellers. As for things staying more "lubed and sealed" with some oil in the intake system, you could be right, I dunno.

I bought a catch tank from heavy PDM and would also like to know how to hook it up. from looking at the motor I would guess on line off the T runs to the black box? and the other runs to the catch tank? Only thing is the catch tank has two line running into it on the top, where does the other run to?

Remove the black plastic box.... and just have your catch tank go where the black box was and back to the T. So you would be replacing the Black box with the catch Tank. Good luck, Chris

[robbbby]

Ok but what about the line under the black box? It looks like it runs back into the block? Do I just plug it up?

Mine has a valve on it, you can open it to drain the contents periodically. Mine isn't a GReddy, it's a JAZ from summit racing, but I assume they are similar in function.

I'm not asking about the catch tank though, I'm asking about the hose underneath the stock black box.

[gtune4]

the catch tank is to prevent oil from going in your intake.leave the "black box".install between the T and your intake hose. you dont want oil in the intake. detonation. doesn't help mixture.
