When you vent to atmosphere rather than to intake vacuum, you lose that vacuum. You need to make up that difference by increasing passive flow capability, i.e. increasing the ID of your tubing/breather circuit. You might actually be increasing crank case pressure if losing the vacuum is not addressed.
Damn I love these jdm channels! Your knowledge its bloody impressive and your description and explanations are so easy to understand haha thank you! I have an r34 gtt coupe with an rb25det, I stumbled across your video's as help to work on my own car cause a car worked on by yourself is far more treasured than a fast car brought. Again thanks from a fellow RB lover from New Zealand
depends on what ur using them for, track use they are not good, but if you just want to drop your car and dont give the slightest about handling they are pretty good tbh
That’s the same catch can I threw on my KA-T lol. Super impressed with the quality I just had to take off the flashing from machining with a needle file and wash it out after
The steel wool is a great idea but wouldnt it make the dipstick not read correctly since the steel wool would be full of oil? Also great vid! I have a catch can in my frontier and i love it!
I recently bought a 2007 Mercedes SLK 280. The intake manifold has three dash pots that control flaps/secondaries inside it with lots of armature and linkage made of cheap plastic. When the intake gets coked up with oil from the PCV the gum and carbon builds up causing resistance and those cheap plastic parts to break. If that happens the intake manifold has to come out and potentially be replaced (expensive). I put in this oil catch can hoping to avoid this scenario. Thanks for the video.
I put one in my 2002 Echo with 308k miles. After 600 miles, it collected 3 oz of oil, water, and gas. Today I put in a stainless steel scrubby pad today to see if the yield increases.
I have this same oil catch can from ebay for about $15 and its garbage because the oil gets sucked right through instead of catching the oil, but mine didnt come with steel wool. Where did you get your steel wool from?
Should you not mount the filter on the outlet? That way the oil-mist needs to first go through the steel wool and then out, now the mist will just go from the inlet and just escape through the filter. That's how i mounted mine atleast :p
I think also the in and out are backwards. I would think you'd want the oily air to come in and go down to the steel wool, then you have a baffle helping catch any left over oil in the air going out, before it goes into the engine. I wouldn't expect any different from the cheap stuff though.
i bought the $200 set of maxpeeding rods w the adjustable top hats for a e36 sedan and they were great! rode surprisingly smooth and handled. but, i bought the $170 set for the NA miata without top hats and this set i got was completely garbage. blown after 1k miles
Yo Question I did the same thing on my RB 20 the same exact in the car smoking white what you think is that. Is it throwing away all the gunk or somethings happening?
Smoking blue is oil, smoking white means you're burning coolant aka your headgasket is toast. But yeah, i would say the issue is not related to your catch can.
Hey adel, great video again like always. I ran my oil catch can setup the same way until I learned that we need to have vacuum to help pull the blow by or else we can blow out our front main seal. Basically just like the oe pcv setup is pulling vacuum from the soft intake tube. You might want to look into that. Anyways keep up the great content! 🤙🏼
Thanks.my dumbass had my lines reversed. I had the line going to intake hooked on the baffle side. I thought the baffle was to prevent suckin up the oil in the can?guess i was wrong?
Is it me or are the in and out on that catchcan the wrong way around? You wont be catching anything if the filter is connected directly to the inlet of the can.
From times i've seen it setup like this, the filter catches all the oil as it tries to escape avoiding the bottom half of the can all together. but thats just what i've seen
Some engines, like the rbs... could do with the vacuum... because they're rbs. (Don't question it) A good catch can modification is to add a tube with holes along it to the inlet that extends to the bottom of the jar. Right now... it's probably going to eventually leak vapour out without catching much. And if I know rbs... I've come across more rb25's that have head draining issues, that benefit even more by adding baffling to the valve covers, as well as performing oil galley mods But you chose the rb life... just send it. It's either going to pour out oil, or not.
I did too. I cut off a little of the metal scrubbie, shook it out to get rid of debris and put it inside the baffle cup. The rest of the scrubbie I put in the bottom of the catch can. I don’t know if that’s right but I figure it can’t hurt.
Manufacturers should at least offer them on high performance engines, and just added one on my Challengers 6.1 hemi. I got a good one though and was made in the US by Billet technology, so it's not cheap Chinese junk and won't put any of that crap on my baby. It's the SRT trim package, so it wasn't cheap and want the best for it
Geovanny Moya it good to have it In there, a friend of mine had a catch can setup that was similar and oil kept splashing out somehow. A ball of steel wool fixed that
If you vented to air without a filter, dirt would find its way into the engine. Also, it would spew oil mist all over the place, making a mess of your engine bay. A good baffled oil catch can solves both these problems.
It's illegal to vent air that has been inside the engine (considered as exhaust) to the atmosphere without extra cleaning. Easier and legal to get the junk out of it and reroute it to the engine
@@darius2640 wouldn't be a smart move to show illegal things to everyone on the internet. Some might use them on their dailys and then be mad if they got fined etc
You could do that but then you get oil all over your valve cover and if you had an engine that has a ton of blowby then this would get really messy, really fast. But yeah, catch can is just there to accumulate it neatly and not cause a mess.
This company sells just crap. I bought a turbo charger from them, that broke on the third run on the dyno. I got a replacemant for 50$ from them, that after the first start in idle already had to much play to run! wtf! Don't buy their products guys

Good review explaining ins and outs of Oil Catch Cans. Been fighting blowby and the messy smoke on my 383 stroker for years.

i was thinking about buying their 24way adjustable coilovers but after reading the customer experience I'm gonna save up for a real set of coilovers.
Jan Prokopenko yeah they are a piece of shit company everything they make is cheap for a reason
depends on what ur using them for, track use they are not good, but if you just want to drop your car and dont give the slightest about handling they are pretty good tbh

This was great. Thank you. There are barely any oil catch can videos on CZcams. I'm serious.
I used coilovers from that company in uk on a few of my vauxhalls and they was really good reliable parts and amazing customer service
Tuned- VXR 😂
Factory designs are for 5 year life cycle, not 26 plus lol ;D I love this can!!!
I use the same exact can. 22.99 on ebay. Does the job just fine. No complaints
I was gonna buy some coilovers for my Sentra a couple months back, test their coilovers next?
The steel wool is a great idea but wouldnt it make the dipstick not read correctly since the steel wool would be full of oil? Also great vid! I have a catch can in my frontier and i love it!
I've have them coilovers in my s13 coupe and have had them in my ute for 3 years never had a problem with them
I have a 19 wrx with the fa20. Been looking at the IAG AOS and curious if this would recirculate it as much as all the hype of the IAG?

how much steel wool is appropriate ? Would the air flow pressure possible cycle steel wool particle to intake causing damage to engine? Thanks
should i install it between the line from PCV to crankcase? or PCV to air intake manifold
Hi didn't you have a hose from air/oil separator on rb? Thanks.
I put one in my 2002 Echo with 308k miles. After 600 miles, it collected 3 oz of oil, water, and gas. Today I put in a stainless steel scrubby pad today to see if the yield increases.
lets be real, u didn't use the supplied hose due to it being shitty garden-hose xD
Should I buy it for diesel?
I have this same oil catch can from ebay for about $15 and its garbage because the oil gets sucked right through instead of catching the oil, but mine didnt come with steel wool. Where did you get your steel wool from?
Nice mod can't wait to install my catch can too!
did u cap of the outlet of the crankcasehousing ?
Thank you for your info sir,
Dose a breather catch can could cause a vacuum leak i have a dodge challenger sxt 2014
This catch cam works a treat on my patrol it's a ZD 30 direct injection for 40 bucks delivered to Australia you can't go wrong
What are you talking about? How do you know it works
Might want to sand the dip stick a bit

you should test a freddy RB intake manifold on your car
I can hear a loud air noise do you know what the problem is or is it normal?
you can use both ports to vent to atmosphere instead of blocking off the port
Yeah but I wanted to have as little hoses in there as possible.
I though about doing a dual catch can setup on my g37 for a good while
You don’t need it, your car isn’t direct injection
Where can I get the two caps at 9:50 ?
Yo Question I did the same thing on my RB 20 the same exact in the car smoking white what you think is that. Is it throwing away all the gunk or somethings happening?
Smoking blue is oil, smoking white means you're burning coolant aka your headgasket is toast. But yeah, i would say the issue is not related to your catch can.
I prefer air oil sepperators
is steel wool a good idea? i know sometimes catch cans fill up with some water as well, could make the steel wool rust.
Blaylock1988 well it’s not recirculating so
@@Riley180sx I think you forgot to finish your thought

I was curious about this since I am doing my research into how to set them up. Was certain it needs vacuum as well
Speak of the devil, I was just thinking about getting rid of my non-functional catch can for one that does work lol
The in and out ports are defiantly labeled the wrong way round. All the vapour is just going straight out the filter
Maxpeedingrods is a funny name
Thanks.my dumbass had my lines reversed. I had the line going to intake hooked on the baffle side. I thought the baffle was to prevent suckin up the oil in the can?guess i was wrong?
Or drop pcv line down to the tire.

but thats just what i've seen
Do you think stainless steel wool added to a can would help ?
Nope
Stainless steel pot scrubbers resist rusting better and don't shed fine fibers like steel wool does.
Is it legal?
So, buy ultracheap catchcan, route breathers into catch can, route output to oilpan! :D
You would think that be a good idea, but you'd be surprised how much moisture you collect in a catch can and you wouldn't want that in your oil pan!
Some engines, like the rbs... could do with the vacuum... because they're rbs. (Don't question it)

What's wrong with a breather right on vavle cover like old school chevys
Blaznmax 88 because it’s a boosted engine it uh does it so much more
Ohhh man new video who dis
That looks and sounds like a giant grinder
aaaaaaaaaaaaay lol
I thought the steel wool went into the removable baffle cup..
I did too. I cut off a little of the metal scrubbie, shook it out to get rid of debris and put it inside the baffle cup. The rest of the scrubbie I put in the bottom of the catch can. I don’t know if that’s right but I figure it can’t hurt.
5 stars!!!

Yooo maxspeeding rods! I run there coilovers there pretty good 👌
cool
You can but this exact thing on ebay for 20$, that what I did
Well. How will the stick work when you scrape it off on the wool when pulling it out 😃
If it's wet then it's full hahah
Just curious, if it's a simply a jar, then why would you need baffling? Is it to keep from spilling?
Pretty much, just to keep oil off the breather filter
Geovanny Moya it good to have it In there, a friend of mine had a catch can setup that was similar and oil kept splashing out somehow. A ball of steel wool fixed that
$37?!? Half that price for the same catch can delivered from Aliexpress lol
If you are running an air flow meter the crank case pressure is metered air, not plumbing it back will make your car less efficient I believe
Maxpeeding rods for the win!
Why don't you just vent the pcv to air?
If you vented to air without a filter, dirt would find its way into the engine. Also, it would spew oil mist all over the place, making a mess of your engine bay. A good baffled oil catch can solves both these problems.
@@finngurgens3264 i ment with a filter. I had a small filter, which is similar to an air filter, on my pcv vent and never experienced any problems
@@nice1149ss oh I gotcha, yeah that often works out fine
Wow ! Thanks for this great video! We are very honored to work with you. And we also hope more chance to cooperate! Good luck!
Way too much steel wool. Just need one of those and that's still alot
Weird design. I can’t see how the output won’t get dirty oil
You’re going to need a bigger catch can.... #rblyfe
couldn't you just toss the catchcan out all together and just stick a breather filter in your valve cover and a plug in your intake manifold
It's illegal to vent air that has been inside the engine (considered as exhaust) to the atmosphere without extra cleaning. Easier and legal to get the junk out of it and reroute it to the engine

Dont use that little air filter or else you cause a vacuum leak on your engine and you wont pull out blow by from your oil which is very bad.
You barely figuring this out??? 😬
Lmao how about a coke can and a zip tie
I did it like this, its working great so far!
Yes. The hand is annoying.
This company sells just crap. I bought a turbo charger from them, that broke on the third run on the dyno. I got a replacemant for 50$ from them, that after the first start in idle already had to much play to run! wtf! Don't buy their products guys
Come here Moroso
no my car does not need this.
Maxpeedingrods coilovers are cheap junk if u want budget coils go with racelands close in price but racelands are better
i see you are misinformed
SlideTribe i have used both and racelands lasted where as the maxpeedingrods blew within 2 months
First
