In this video I show you how to make your own catch can / oil separator from scratch. Help keep the excess oil out of your intake and keep our car running better, longer by installing a catch can. This is an easy and innexpensive way to protect your cars internals from oil fouling. Watch the entire video as I show you a step by step walkthrough of how to build this catch can. Any questions, comment below.

I know the next time I need some sanding done I'm calling this guy.

After watching your video I will now redo and change my catch can to make it perform better. Thank you for your video. Good job

I loved this simple tutorial. Great how-to for the car diy guy.

Well done, enjoyed every minute of your tutorial.

This is great! Thanks so much for sharing, I love watching little nightly, crafty things like this.

Thank you for your time and instruction. Excellent working design.

great information using readily available parts. Thank you So much

Good job, very informative.

Thanks for the great ideas. I'll be installing one on my 2011 F150 and my 69 F250.

Thanks great stuff I will make one for my car too thoroughly enjoyed watching this got my creative juices flowing now. Kind Regards Cape Town South Africa

Very nice work..I saw many who make Oil Catch Can..but you are the best..you are really good

Sweeeeet ...... I’m a gonna do it to my 2016 Tucson . Great 👍 idea 💡 since this a problem I had on my old ‘04 Santa Fe. Thanks again MDIY 👍

This is what KZfaq was made for, great work mate.

Great simple design. I have the following ideas for improvement 1. Drill 2 holes on cap which holds the inner separator - establish the center of the separator and also the center of the cap... drill holes and fix the divider to the cap from the very beginning. 2. Glue cap to tube only after the separator is fixed to cap and inserted inside tube as one component. 3. Drill holes for inlet and outlet ports. 4. You could create a sieve type of cap on bottom and you wouldn't need anymore the cross linkage which notches into the main wall of the divider (you allready can grab that from a manual meat grinder). 5. The notched small divider should also be screw held to the main divider wall.... don't really trust the glue holding on for many many years when subjected to oil.... also.... I've rather avoid using glue which interacts with oil.... The end product looks really nice :) for the amount of money invested.

Sigh, just when I am about to lose faith in all humanity I stumble across your amazing video tutorial. And my hope has been renewed. Amazing job sir. Well put together, both video and oil catch. Appreciate you letting us know how long they have lasted before.

VERY WELL EXPLAINED. LOW COST

Nice work. Great video.

THANKS . GREAT JOB. VERY IMPORTANT DETAIL TO MY TRUCK

This is so easy I'm going to make one for my car.

Cool thanks,nothing beats hanky inginuity.

You ARE AMAZING this is a nice idea

Thank you my brother this was just what I needed for my 2012 Ford Mustang Convertible and it have work wonderful and safe me some serious money and I took pride on make in it for my self, thank thank you so much for this DIY for sure 👍

Well done great video, well presented and very informative

very interesting proyect. THANKS SO MUCHO SIR!!

Great Video

Wow that is so good.

Awesome video. Love it! Betting your Italian.... bc you hand movements reminds me of the Sopranos. ;-)

Thank you for that awesome instruction amd it's the.same as my highlander engine

Good job

Thank you. Looks good !! The only change I'd make would be to not glue the top cap so you could remove it to change out the clogged up screen after time/miles go by. Because the top of the drain valve protrudes up into the bottom cap there will always be a 'pool' of oil at the bottom. But that is a good thing because the 'pool' will better attract the smaller oil droplets, and not clog up the screen as guickly. Thanks again!!

You did the right thing, use your mind, just let it goes on, don't tie to limits💪 😉✌️

Thanks

Thanks for the video, nice job. An idea to aid with installing and lining up the separator/baffle with the top screw hole would be to put a length of stiff wire down through the screw hole and into the baffle hole and then just slide up into place using the wire as a guide.

Enjoyed, yr recoursfullness, great, Bob from Belgium, keep safe brother! 🇧🇪😎🤜

شكرا على توضيح عمل فلف بخار الزيت

Thank You

very good show

Seeing your Toyota engine, I’ll do it to my Scion xB. Thanks.

When drilling the end caps in the vice, put an offcut of pipe below it for support.

Great idea and design. Try out pan scrubbing pads as a filter media.

EXCELLENT idea and very economical solution!! Thank you so much for this. 👍👍 Nearly every Car Engine needs this! ........ Just one thing. PLEASE!!! This has been wrongly named for nearly the entire 60 years it's been in existence. P-C-V - Positive Crankcase Ventilation Valve..... It's NOT P-V-C!!!! (Plastic Piping!) 😖 Please, people have been messing this up longer than calling a CAMARO a CAMERO!! (Even some nitwits who OWN the Car) You are definitely providing an invaluable service here. Don't lose some of the audience by misnaming it. 😊

Wow, simple to do. Thanks for the show... Just one thing though, I can't seem to sand that fast. I just wonder how you do that without catching your fingers on fire... hehehe, just kiddin..

Very good 👍work

Very Nice, Hope you do other stuff and post it on your channel. GOOD JOB!!!!!!!!

Brilliant

Would be nice to include a way to take apart to clean? Or inspect the media in there?

This is perfect, wayyy less expensive than a store bought one for almost $300

Great video, I think I'll make a similar one, although I think I'd prefer 3" PVC pipe & caps. Unsure yet what I'll use for that flat material inside, but will check out Home Depot. The only thing I'll change is the type of screw/drain you used. I would like a simple on/off valve that I can open and close, as I want to install some clear tubing to it, so I don't have to try and get a 'catch-all' or have to take the catch-can off, to drain it. Having a simple off/on drain (similar to a water shut-off) with some clear tubing going down and under the vehicle, I can put the end of the clear tubing into a regular empty oil can to collect whatever is in the catch-can. Then just coil up the clear drain tube that hangs under my vehicle, and use a zap strap to attach it to one of the truck parts that would work for that purpose! Thanks for the video, much appreciated!

Well done... But u I think you could also reinforce steadiness of the separator by fixing it with 4 or so screws at the sides.

Explained how it works and how to build. Thanks

Great video. Your channel should be called "Talking Hands Italian".

Excellent design. PVC holds up perfectly under the bonnet as long as you avoid the exhaust. However if and when I make mine I will be gluing/sealing the sides/edges of the long baffle to avoid engines gases taking the shortest path which would make the entire unit almost useless imho.

Thanks for your great work and all the time you spend. I am intending to connect the catch can to the oil dip stick in order to add the filtered oil to the oil sump. As it is designed in many original OEM PCV oil separators (From BMW for instance). for your kind advise.

A copper scourer works well to condense the oil vapour. Honestly I bought one on Amazon for $24 AUD with baffle and sintered bronze filter and a drain valve it's about six inches but well made from aluminium.

nice vid..

Lindiwe likes it thanks!!! yeeeehaaaaa

Truly a great idea for little money and effort.

Could we get an update on the crud you caught with this setup? Nice work

I subscribed

I'd like to make an observation: the positive pressure in the crankcase is caused by gases (not gasoline) getting past the rings into the crankcase. All that moving hardware stores the air but doesn't create a flow of air under pressure. That said, I'm making one for my GMC Sierra with 174,500 miles, pushed by a 6.0L OHV.

I think, that you should mount the catch can below your PCV outlet to ensure correct flow of the oil. In your case, you built oil catch hose not can.

Great idea and good introduction, but I do not recommend neither PVC nor the elbow you mentioned. First PVC is not suitable for this application since it is not heat resistant and the inner surface of your DIY OOC could slightly melt since oil vapour is about 120/150°C when it comes out from the crankcase (traditional product PVC has a maximum operating temperature around 140 °F (60 °C) when heat distortion begins to occur). PFTE, aluminum or titanium are more adequate for that application. Also, steel has some problems since it might rust when it comes in contact with water. Secondly the elbow fitting you have used it might reduce the speed of the flow, 90°C radius should be avoided, rather a straight way fitting might work better. Finally, all fittings have been radially installed, while the inlet should be tangentially installed to let vapour slow down and maximize its contact with the OOC lateral surface to rapidly cool down and then condense, while the outlet vertically should be on the top of the OCC. Moreover, for anyone who wants to install it on the turbo charge engine, bear in mind to install also a check valve (also known as no return one-way valve) after the outlet, in order to avoid any reflux caused by the high pressure generated by the turbine and coming out from the inlet manifold. That being said, it is a great DIY work, but for a more effective protection of my engine I'd spend few bucks on Amazon. Cheers

Has anyone noticed he tells you what PCV stands for but every time he goes to say it he says “PVC”. Positive Crankcase Ventilation (PCV) system

i could not help to notice the pcv valve was called pvc valve, also you are working with 2" pvc pipe not 2.5" , also you have no need to sand inside the fittings, by cleaning the surfaces with alcohol, or using a primer for pvc before the red hot blue will create a nice glue on, other wise i like to thank you for the great effort and great job, the fittings i would recommend to use brass barb adapters for durability, and yes it is more expensive but it will last for life,

Great job thanks, the mesh bit did you put it in the outlet or the inlet?

Greate idea thank you dr...... Shall I cover the middle sapareter with mesh ,is it ok know?😀😀

Yes pvc

Just a tip, to snooth the corners and name marks, usa a razor insteado of sandpaper.

The EGR also contributes the the problem.

The screen you put in is it on the airflow side coming in?

Thanks for the video. I have a 2010 chevy traverse. The air line comes off the the back of the enging into the intake. On the front left of the enging, the pcv line comes off the engine connect and onto the air filter hose, between the throttle body and the mass airflow sensor. The oil is collected into a cup like holder, but it is getting suck onto the throttle body when air is being suck in my the engine.So my question is, the oil caan would be connected on the front of the engine where the pcv comes off yes?

Well done, nice design. How about putting the "screen material" on both sides of the tube, so that air vapor is filtered coming in & also going out. Also, this would allow the intake/output ports basically be the same. A nice, well done video.

After you use a fuel injector cleaner your intake manifold and throttle body gets dirty be aware cause have to clean it too

👍👍

Could you please explain what is the filter material? It is a metallic or plastic, or something else? I mean what exactly you put into can as oil filter?

hi, I have a 2006 Infiniti M35 and has some oil go to the intake manifold from the pcv valve and from the breather hose to the air filter housing so my question is can I install 2 catch can ? because all the KZfaq videos about this matter only focuses on the pcv. thank you

That was so dam beautiful I wood like to buy one from you

Sooooo...first there was no catch can...now there is...was the hose (with two different connector sizes) direct to pcv valve from intake manifold? So....now oil will be caught in the can instead of smoking (on my bmw)? Thanks, fun, informative video..)

Looking to make one out of an 8oz mason jar. Vent holes in lid. What do you think? Pros/Cons?

What's worse: egr or pcv?? I actually purchased a cheap knock off provent 200 catch can, but it's so damn humongous that I'm gonna do exactly what you've done here. Would you consider having the bottom capped end threaded so you can periodically check the filter over time? Thanks for the very clear and concise mister, love your work. Subbed.

Nice setup. Are you having any issues with under temps and the pvc pipe?

My 2005 Tahoe doesn't have a PCV as fsr as I can tell. Can I still install a catch can?

Hi, Nice video!! Easy to make it :) I have a question, do you want to make a video of the the results? How many oil/ water has collected the jug?

PVC flat piece: What part# at home depot? I cannot find it at my Home Depot

what would happen if I just unhooked the hose that returns to the intake?

Is it possible to design it in such a way that the oil just flows back inside the valve cover? The maintenance is probably gonna be awful😅

pvc pipe has too low working temp for underhood and hot engine blow by. Please post and let us see how it held up.

I wanted to know which metal should I use for catch can to get better performance in engine of formula racing car.

what can be use as as the separate material ?

Are those hands yours?

Positive ventilation, btw

Thanks for ... made in USA.. Feel free to 😮

@markosedlarik9553 prije 0 sekundi I have a question now. This is a 2AZ-FSE engine. What is the point of oil catch can when there is also a bigger outlet hose on the right side of the engine which is also connected to the intake manifold through the rubber tube?

This was a long video so I may have missed it but what did you use for your hoses?

Hi just wandering if it's good here in northpole canada with -40? And thanks for your time!

How is it working sir?

Can i use it in diesel engine?

You forgot to glue vertical walls of the divider. Without that its like you didnt put divider at all 😅

Simple mistake but at 1:57 you said PVC.......lolol.....Great video though. Good info
