$2.99 Oil Catch Can

[Morgan]

After disassembling my supercharger the last few days I didn't notice any oil in the charge pipes or in the manifold assembly, but to make myself feel better I got a $2.99 see through fuel filter and installed it in the PCV line. When/If it fills up its cheap to change and saves valuable space in the tiny engine bay. Here's a picture:

GREAT idea!! wow

[KCALB SIRAY]

I'm so hot for you right now because of this, lol. Seriously, great idea

[kngrsll]

got a part number or what car it came off of by chance?

[marcus]

now im confuse i thought its suppose to be on the otherside..

like this.. http://www.yarisworld.com/forums/showthread.php?t=5294&highlight=oil+catch

Purolator F21111, any cheap filter will work though. But for the record it came from PepBoys and there were other sizes to pick from that I'm sure would work just as well.

Kcalb- umm, thanks? lol

now im confuse i thought its suppose to be on the otherside...

both ports do the same thing, my other one is capped off...

That's pretty gangster. I like it. I think it's cool.

[firebob]

I think the oil will go right through that element and there’s no place for it to drain but into the intake.

If you show me the case of those filters so you can change them all the time I give you a +1 but if you didn’t get a case of them then you get -1 for cutting the hose for no reason.

[yaris-me]

Did you use an electric zip tie on the hose to secure it?:thumbsup:

:eek:

:rolleyes:

so, unless she bought a case of them before knowing how they'd work, she gets a -1... wow dude.

[firebob]

I would think that holding it up to the hose and looking you could see it would see that the oil would soak through the filter element and go right into the intake. That’s where the -1 comes in.

I’m sure the cost of the hose is about the cost as a case of the filters I bet.


I would like to say that I’m sorry for giving it a -1.


But now that I look at it closer I give it a +2 for re filtering the air that’s getting sucked into the crank case. If you want it to be an oil catch can then it needs to be on the back hose coming off top of the crank case unless it’s different on the 08 then the 09.

[ddongbap]

Soo.. wheres the catch?

[Morgan]

Considering not all engines (not even all 1nz's) are created equally, an oil catch isn't absolutely necessary on every engine. So I either wasted $2.99 on a fuel filter since my engine doesn't have a blow by problem, or I wasted $2.99 on a fuel filter because I would have to buy a much higher capacity oil catch later on, or like I said in the beginning I was curious to see how much oil was actually going through the tube...

But guess what?!?!?! if the filter soaks 100% with oil, the car will still function! Amazing right! :rolleyes:

[firebob]

With it on the wrong hose it will only see oil if you have an issue.

[firebob]

In post #1 it says in the PCV line.

[Morgan]

In post #1 it says in the PCV line.

Pull your valve cover. Both of those tubes do the same job. One tube goes to the stock intake manifold, while the other goes just after the MAF. They do the same job. It is redundant to have both tubes. So during the supercharger install, I capped off one of the tubes since my new intake/supercharger set up only had one port (cause it came from a Scion xA/xB and they only have one breather tube). Since I only have the one tube that is where I put the filter.

Both tubes are not necessary for the car to run, Toyota makes redundant systems for reliability and this is one instance where I am willing to give up some of the redundancy to save space.

I suppose you could install the filter in the other line, it would make no difference whatsoever. However, for a catch can to be most effective you need to make sure all pcv hoses are going to the can to get all of the oil that passes through makes it to the catch can.

[firebob]

Ok sure.

But both hoses do not do the same thing.

The set up is to pull in air form before the throttle body through the crankcase and dump it back into the intake. The hose that dumps back into the intake has the check valve. When you let off the gas the throttle body closes down most of the way and the motor would suck air though the crank case and burn off the fumes in the crank case.

But with only one you will only get blow by and a bit of air from the change in the temp as the car heats up and cools down out of that hose. I didn’t see that you had removed the other hose.

I'm confused. The hose from the PCV goes to the intake manifold after the throttle body and there is another hose that goes after the MAF. What is the point in having two? After throttle shut down wouldn't it just circulate air through the hose to the manifold?:confused:

+1, mine was originally set up like this too, on the atmospheric pressure hose, and never caught a drop of oil. It's gotta be on the vacuum hose connected to where your stock manifold used to be, as the vacuum in there (off-boost now, obviously) is what will suck the fumes through the system. Otherwise you're just filtering clean air.

vacuum sucks, simple as that. There is a difference in pressure on the ends of each hose, so the PCV system works as a kind of restricted bypass

[firebob]

There are 2 hoses.

#1 goes form the PCV valve that is screwed into the crank case to the intake.
#2 goes form the air intake to the crank case.

In the red box is #1. The black fitting is the PCV valve.
In the green box is where #2 should be. With a stock car this would only see clean air.

where did you get this information FORM? :laugh:

[firebob]

I guess I can’t spell after 11:30 at night after being up all day and drinking a few. :drinking:

[yarisugi]

What is the inside diameter of the hose that you're connecting it to?
I might do the same, but need to know the inside diameter

so does this mean we only need one filter which is on the red box.

I had a small length of 3/8" [I think that's the size it was] tubing I put on the filter then put the ventilation hose around that with a zip tie, there's a lot of stretch in that hose once you cut away the protective wrap. But the filter does have a very small inlet and outlet so instead of zip ties a screw clap might be an easier solution.

[marcus]

anyone confirmed the 5psi drop for using the filter is that affecting any hp at all..

[eTiMaGo]

It should not, that PCV section is basically just a bypass, any air that is slowed down there will just go through the main intake tubing...

[Tamago]

vacuum is not measured in PSI

what psi drop are we talking about? i guess i should have read the rest of the thread.

[marcus]

ok thanks etimago..im on this.


psi drop due to oil filters.. which mean itll slow down the air going in the intake but as etimago said wont make a difference.

psi drop where? where is the psi drop?

[marcus]

psi drop where? where is the psi drop?

its says so on that specific filter when i went to homedepot/canadiantire to check it out right on the filter itself says it will have " 5 PSI " drop by using it.

5psi drop at what air flow?

[marcus]

5psi drop at what air flow?


the excess air coming from the engine thats being recycled back to the intake. that air is whats being filtered due to oil that goes along with it.
i could be wrong though so check with the person that did this already im still in the process..

psi drops depend on the amount of air being forced thru them. if you were to blow thru the filter with your lungs you would not be able to generate a 5psi pressure drop. it would take an extreme amount of air flow (air compressor) to generate that 5psi drop.

the minimal air coming out of the valve cover is not going to cause a 5psi "drop" in this filter. i'd imagine you'd see no drop at all actually.

[marcus]

i guess that only apply for air compressors...so i guess it has no effect then..

[Tamago]

yup, you're in the clear! :)

[marcus]

ill pick it up this weekend..

[yarisugi]

OK. I'm throroughly confused. Where does what go where?
Referencing firebob's picture (red square, green square):
RED SQUARE --> hose --> FILTER --> hose goes to where?
GREEN SQUARE --> hose goes to where?

[marcus]

red

[firebob]

LOL we have a new run at this fad.

I will say there was one point that I was close to installing on at one point but decided that pulling the hose off the fitting every oil change I could feel for my self without having to modify stuff.

[marcus]

huh? dont you just need to empty the plastic case anytime you want ofcourse b4 it gets full..

[yarisugi]

what?

[saplaymate]

[yarisugi]

Thanks for the link... Do we have a PCV valve on our car?
So the filter goes between the crank case and hose that connects to the intake pipe that's between the throttle body and air cleaner?

[firebob]

If you look in the RED box off the pic I posted you can see the threads of the PCV valve.

If you look at the link that saplaymate posted the Yaris is set up like the second pic of the motor.

[eTiMaGo]

another related mod that I have not yet seen anyone do, you can replace the atmospheric pressure hose (the one on the front) with a little breather filter. Absolutely no advantage over the stock setup (and you'd have to plug the hole in the intake tube), but it looks pretty cool

http://www.jackstoolshed.com/index/page/product/product_id/2034/product_name/Pro-Grade+Air+Tool+Protection+-+Water+&+Oil+Separator+Filter

would work nicely IMO. allows you to catch and release any oil that passes thru

[goliath1812]

sorry for the thread resurrection....but has anyone used this crankcase breather filter? any advantages or disadvantages?

[CB900F2]

Hi Morgan.. Can you post a recent photo of the filter?.. Wondering how much oil has been captured by the filter since new.

Thanks
