catch can
...yeah, so i really doubt this is the right forum to put this in, ::)so sorry if it shouldnt be in here, ;)but anyways, anyone know the best/cheapest place to get a greddy catch can or something real nice looking in a similar size?
|
Re:catch can
i've seen some nice ones on ebay for about 50-80 bucks. correct me if i'm wrong but isn't a catch can just a catch can, i mean brand shouldn't matter on this item would it?
|
Re:catch can
greddy catch can at www.lightningmotorsports.com is like $80-90 + ship
summit proprietary catch cam at www.summitracing.com is 14.99 free ship the summit one works, so dos the greddy one, the greddy one says greddy on it |
Re:catch can
i say greddy just cuz its the perfect size and it looks so damn good too... ;D ive seen em on ebay for bout 80ish, just wonding if anyone knew anywhere cheaper for something simmilar. obx has a replica of it i know that, but idk who else might...
|
Re:catch can
summit racing has really nice ones but i don't know how much
|
Re:catch can
just make one. even a complete moron can make a perfectly capable catch can, and if you make it yourself, you can at least make it to the size you prefer.
|
Re:catch can
yeah, but who knows what it will look like... i can easily make one out of 2.25" piping and sheet metal, but it wouldnt look near as good as a greddy or obx would.....

Re:catch can
sup guys! i do notices my car is burning oil after i turbo it, it burned like 1/4 quart of oil a week. i check my turbo and everthing else, but i don't see any leak. is my oil going to the itakde through my pcv valve?
|
Re:catch can
turbo z24 guy i got some greddy for sale. $1.99 a pound. let me know.

I think you should sport some authentic JDM ---- on your Jbody ;D |
Re:catch can
hahaha. jdm ---- on a j-bod...hehe. ya know there is a thing called a Toyota Cavalier right? right hand drive cavy with a few diff appearance things sold only in japan. GM and Toyota went into a small partnership to make them.
that catch can looks real nice though...who makes that one? and i cant find the damn summit ones.. :-\ |
Re:catch can
Summit sells them.. just need to look harder.
that can is made by Cusco, Jdm Bling Bling.. or theoldone has a nice setup for hondas/acuras http://www.theoldone.com/components/...eather-Kit.jpg guess it could work on any engine really.. I'd just make my own personally ;) |
Re:catch can
Is there any photos or article I can look to install one of these catch can? Please dont tell me to search my comp takes forever just to load a page. Thanks guys.

Re:catch can
I don't understand why anybody would run a catch can, its pointless. You should run your breather to a crankcase evacuation kit that is actually functional becuase it relieves the pressure on your rings, stops blowby and is even cheaper than a catch can (under $50). If your car blows smoke, this will help if not stop it
|
Re:catch can
i have a breather filter but oil starts to build up on the filter. its better to rought it back into the intake so it "sucks" the pressure (blowby) out of the crank case. and i dont need that oil and ---- goin into my turbo and inercooler, so im gunna use a catchcan...thats why, lol so no, they aren't pointless. they're great. i think anyone running boost should have this setup. hell even NA guys should if you ask me. still suction (vaccume) on NA motors, jsut not as much as the turbo would suck.
|
Re:catch can
Do you know what an evac kit does? Its kinda like a one way valve you weld on your downpipe. You than run a hose from your valve cover to the valve on the exhaust. The vaccum caused by the exhaust helps to pull all the presssure out of the crankcase and actually prevents blowby, the oil in your charge pipes and all that other ----.
a catch can only holds the sludge instead of fixing the problem thats causing the sludge. I just think that its better to solve the problem with something that will actually free up power and help your motor run more efficiently instead of a can that catches oil. |

Re:catch can
Both these kits come with two of everything for v6/8's with two cylinder heads I assume. Could one be used for the head and the other for the bottom half?
|
Re:catch can
Yeah they are sold for V8's so you only need 1/2 the parts.
http://www.moroso.com/catalog/images/25900_part.jpg The 2 big things all the way to the right are for a V8 valve cover so you don't even use them. You weld the threaded pipe onto your downpipe and thread the next bronze thing (the one way valve) ontop of it. Than run a line from you valve cover to the valve. Now you have a functional way of decreasing sludge, less weight than a catch can and MORE POWER for the motor. When we put this on my friends turbo Honda the seals stopped leaking around the turbo and it stopped blowing smoke. Now again why would you want to spend $100 on a catch can when you can do this for $15.00 (sell the other half of the kit) |
Re:catch can
i was thinking hook up one to bottom end of engine also and pull air mass out the lower end also should work right?
Before going on to diesel engines, we should mention the pumping action of the underside of the pistons too. As a piston descends, it must displace the crankcase air under it. Similarly, when it rises it draws crankcase air behind it. At low speeds, the movement of air under the pistons balances out since on most multi-cylinder engines there are always as many pistons moving down as are moving up. At very high RPM, the crankcase air really doesn’t have time to move back and forth from cylinder to cylinder. Instead, it just compresses and expands under each piston, but again, expansion balances compression and there’s no pumping loss as a result. One of the benefits of a crankcase evacuation system that depressurizes the crankcase is that the density of the air beneath the pistons is reduced, further minimizing pumping actions. http://www.bankspower.com/Tech_todaysdiesel.cfm |
Re:catch can
now does this prevent the oil from going all over the place? but i still dont understand why its need and how its caused?
|
Re:catch can
sooo then wouldnt any oil just go into the exhaust and burn off then? id rather just have it slowly collect in a catch can rather than brun it all off in my exhaust.
|
Re:catch can
i think i would rather have no chance of oil going back into my intake to lower my octane and gum up the intake track. but that is my opinion. also this is suppose to help out in high rpm situations. i guess its all up to you and what floats ur boat
|
Re:catch can
The oil that would be caught in the catch can would be blown out the exhaust. However, it would also relieve the pressure that was put on your rings by excessive crankcase pressure. Its whatever you want but an evac kit would actually free up horsepower instead of an overpriced catch can that does nothing
|
Re:catch can
they are calling those things that go on top of valve covers "oil seperators" i wonder if they do that or if thats just their name. because it would be a much cleaner job just to run the hoses off the nipples already provided
|
Re:catch can
Well a friend of mine tried using an evacuator like that on his car, said it didn't work. He has a 3" pressbent exhaust and one large straight-thru muffler. I know these evacuators kick ass with open headers but for some reason they run belt driven vacuum pumps on race cars that are required to have mufflers.
Does this stuff really work with an exhaust system or is it a open headers/downpipe only thing? |
Re:catch can
They work fine with open exhaust or full cat back. the exhaust is creating the same amount of vaccum pressure
|
Re:catch can
I know they work fine with open exhaust, but I wasn't sure if they worked at all if there's some sort of a muffler.
I'm thinking about putting in an alternator from a diesel truck. Those have vacuum pumps attached to them for powering the brakes since diesels don't have a throttle. I need a bigger alternator on my off-road truck anyway, to power a set of 120W halogen projectors, an added bonus is it can back up as a welder for off-road repairs. |
Re:catch can
I see two downfalls. 1. emissions 2. gumming up your cat
|
Re:catch can
emissions, what emissions
cat, what cat......lol ;D |
