After debating about weather or not the oil catch tank was worth it or not I decided to give it a go. I'll let you know a a few hundred miles if it has caught any oil that would have normally made its way to the intake manifold.

There was some funky stuff with the install for the xB. The Greddy instructions were unhelpful and almost nonexistent and believe it or not the xB service manual is devoid of any PCV info, so I thought I'd put up some info that hopefully is helpful.

Oil catch tanks come with either 9mm or 15mm hoses. Most Japanese cars (including ours) take the 9mm variety. However, just to make things challenging Toyota decided to make our Positive Crankcase Valve (PCV) hose 9mm on one end and 18mm on the other. This means that you have to reuse the ugly grey stock hose for one of the connections rather then the cool GReddy hose with the cool blue clamp that goes on the oil catch tank. ____.

If you look at the first picture below you can see I marked A, B, C and D. "A" is the PCV (valve) located at the top right corner of the valve cover under the engine cover (which has a 9mm opening). "B" is the input into the Intake Manifold (which has an 18mm opening). The stock PCV hose normally runs from A to B (I have a green line draw to represent this). All that you do to install this thing is put it between the A - B connection. The clear hose going from A to C (the oil catch tank) came from Greddy. The grey hose going from B to the green D is the stock hose I had to reuse because the greddy hoses are 9mm on both ends.

BTW, I had to cut off a foam wrapping that used to be around the stock hose. I think it was there because it used to run under the engine cover and needed to be insulated from heat. Also I am hoping to cut along the red dotted line that is circled and get something that will allow me to join the 9mm Greddy hose for aesthetic reasons.

Yeah, its is a cool addition. rampagesd did it and it looked great in person. you shoulda replaced the pcv valve while you were at it.

The valve wears out and gets dirty after a while ( about 10-12k miles) if it can't open correctly when the intake manifold creates a vacuum, then you aren't going to get the proper crankcase ventilation. Can lead to worse emmissions, dirty oil and more fumes venting back through the PCV inlet and into your iintake.

So what is the verdict? Did it catch any oil?

On my turbo'd corolla, I have oil all over the place because I dont have anything to catch it.. I have puddles down by my fuel injectors.. that'll be fun to clean out ..

So what is the verdict? Did it catch any oil?

thanks for bringing this back. i am wondering the same thing

so, caught any oil? im still wondering..

caught anything?

Sorry for the late reply. Well, its not exactly spilling over the top thats for sure. In fact, the clear tube on the side that shows how much waste is in the can is not filled at all. However, the tube is discolored with a yellow, oily residue and so is the inside on the can. So, I imagine that this same reside would make it back into the intake manifold otherwise. Keep in mind that I only have like 3100 miles on the car so perhaps down the line I'll have a better idea. My cursory opinion is that this is not a vital mod that you will notice when driving, but over the coarse of a few years it might make a difference in the reliability of the car. However, it looks bad ___ and was fun to install, so for $85 was worth it IMO. For those with any kind of forced induction that might create a higher volume of blow-by gas the oil catch can would be a good investment.

just curious whats the ree thing between your rad hose looks like it says TC?

thats the temp sensor for an aftermarket gauge.

you can buy that clear hose at any marine parts stores in all kinds of sizes. Just thought Id let you know so you could take that ugly stock hose out...

I'm not trying to be an _______ but putting a catch can on our cars is a waste of money. These tanks are used for forced induction engines and/or engines with HIGH compression. If you want to install this in your car then go for it. You'll catch minimal oil and it will take a LONG time to get any noticeable build up from our engines. Once again, I'm not trying to be an ___ or start a flame war here. Just wanted to post what I know up here.

Zach

well in referance to yer post they do have high compression motors but they dont spit oil like fi motors by any means

What's the compression ratio for these motors? When I say high compression I mean 11.5:1 or higher. I thought these were 10.5:1 or so. I could be wrong though, I am a noob when it comes to Scions.

Zach

yeah 10.5 i believe thats still pretty high. npt really high but pretty hi. lol but yeah

anybody got a part # for this catch can..im going to a turbo set up and would be nice to have this.

Zach,

Toyotas are known for sucking oil. I have this on my xB and the clear tube was coated within a day. After you get your xB, drive it on the freeway for a couple hundred miles, then pull off your intake manifold.

It will be coated, though not heavily and dripping, with oil.

Sure it'll take a long time to fill, but I don't want any oil coating my intake.

I did this mod to my Celicas when I had them. The Matrix is next as soon as I regain the use of my right hand.

ewww :lol:

It just seems odd to me that an engine like this would have a problem with oil blow by. I guess I need to do more research on Toyota engines. Thanks for the tip Squirrel.

Zach, You're welcome. I'll have to show you my xB one day.

Sounds like a plan to me. I'd be interested to see how much oil actually goes through there. How much oil are you using in between oil changes? Any risk of running low to the point of damage?

Zach

Zach,

Its not ALOT of oil, but enuff to coat the intake. Nothing major like a quart or anything. I'm still using 4 quarts at each oil change.

Its more preventive than anything else.

Its not like when I had my race car and had a few ounces after every session.

I hear ya on the race car thing. My RX-7 burns about 1 quart every 1500 miles. But it is supposed to do that so I don't worry about it. The oil blow by of Toyota engines was news to me though.

Zach

This sound slike a cool mod but can I fit this with a AEM COLD AIR INTAKE?
SomeOne Drop me a LINE

JERMDOC

oh yeah there's way more room with an intake versus stock. WWWAAAYYYYYY more.

Anybody got that part # or a link..PLLZZ!
Didnt see it in the "under the hood "section in the scion store

Probably not the best price out there but a here is a link to the product and part numbers. Loads of places sell them. Do a Google search and then compare prices. $85 to $95 seems like the current range.

thats not too bad..Do i need that "T" bracket too?

How did you mount it in there? It looks like I can almost see a bracket but let me know plz.

Yup. I got the "Universal T Bracket". Its sold by Greddy and you can order it at many of the places that sell the oil can. Basically it lets you mount the can anywhere that the bracket can bolt to. It costs like $5 or $6.

swee the fuji is gonna order one.

got my oil catch can off ebay for 15.00 came with all the stuff to mount it but no instructions (not that it matters) tight fit inbetween my full cold air intake but it works. after driving for 2 days the line looks pretty much clean but slightly greasy inside but i dont expect to see any oil in for like 3 months at least

Since this thread's been resurrected, how are people liking their catch cans after many months of usage? did the oil continue tobuild up? worth more than bling?

Does brand really make a difference? WR is the cheapest name brand that I've seen (only one under $100). There's also the fleabay route.

how do these things work? by having a cool surface for the oil to condense onto? If so, then brand only matters for the bling factor.

thanks

well only problem i had was the seals were leaking oil on my Inake pipes and the tube that came with it was flattening out under the suction along with there not being a large enough hole for proper air to go though , removed it and bought a heavy duty replacement hose , still gotta go through and reseal all the seals and then dill out the input/output holes before reinstall, personally i dont think it makes much of a difference

I am gonna be gettting the new Weapon R oil catch can this week and I had to wait for almost a month.
The NEW Weapon R lays vertical.

Seems like a lot of work. Lately, whenever I go cheap on car stuff I always pay for it later.

I hope the Weapon R isnt cheap crap.

71 dollars with shipping.

what about connecting it to a forced induction setup?

jus got my greddy catch can today, got the verticle one though. pretty easy install looks nice

What is the difference between the G-ready oil catch can, vs. this one:
http://www.scionlife.com/forums/viewtopic.php?t=180338

Sounds like the vertical mount is the way to go. I'm not about spending unneeded $$ extra money on my car, if a $25 unit will do the same job a $85 unit will.

Please advise. :bow:

no real difference. The eBay ones are typically not as high a quality, but it should be fine. I used one and didn't have any problems with it. Of course, on my Rex I bought a Perrin can (much more expensive) and it was high quality and it installed a lot easier since it was made for my car.

Nice info!


Thx

The few people I contacted in person, basically said the units functionality isn't that significant overall. I'm still up in the air about it.... but still leaning towards NO.

I just picked up a CUSCO 9mm oil catch for 56 dollars shipped on ebay.

If anyone is interested....
