It's way easier to clean the EGR pipe and the intake manifold inlet connecting to the EGR pipe. Now, I went for a "deep clean" and What really helped me (removed the EGR assemble) was using an extra reach 12 mm racheting wrench for the three Nuts in the back of EGR cooler. I had a hard time reaching the 4th HIDDEN 12 mm nut underneath the EGR cooler. Finally, used a Torx E8 socket for the two Bolts ( in the back of EGR assembly) and was able to remove the dang thing. Awesome video and very informative on OIl Catch. Thanks NAB!
Installed the catch can and everything went well. I tried the "simple" method first by going under the car and it became impossible to continue because I could only get one hand way up there. It really wasn't that hard to take off the intake manifold. However I did use the "simple" (as suggested below) idea of cutting the small end off of the existing PVC valve hose and using a straight connector to the catch can hose. Even though I only have 85000 miles on my 2012 and have no noticable oil loss, there still was a wet and hard oil crust all inside the manifold and valves. I'm very happy with this idea. Thanks!
Thank you for the video! I just did this work (along with intake manifold cleanup, PCV valve, EGR line). Can is only $25 on amazon now . Couple improvements: 1) you don't need a new larger tube adapter. I just re-used the PCV->intake on the larger side, flipped it up, then bought a 90deg elbow (1/2" shark water line works great) and ran 3/8 fuel line (5ft was perfect to do both, cut at the OCC when done to get max even lines - supplied hose is too thin). 2) as other said, not need to pull coolant lines off (put throttle to side) 3) ordered the plastic bracket from 3D online vendor (white ABS for strength/heat) for $11 (second was just $3.50). Had to sand it to fit diameter (little tight). just put it all together and everything runs fine... onto EGR cooler next (harder project) as the EGR pipe had some serious solid chunks of carbon! intake manifold connection was really clogged too.
@@sungn4512 yes, I did an oil change about 3k after putting it in and it had ~2mm of liquid in there (seemed more watery and gaz smell than oil consistency). haven't done a full 10k change yet, but it already registers on the stick now. Anything to keep the EGR cooler clean is good in my book as that was a pain to take and clean.
Did anyone use the steel wool catch can comes with? I don't think I'm going to use it because of the potential of it to rust. I may put some type of pad to soak the oil or to prevent sloshing.
Is there a reason why the exit pipe is a 1/2? Since the intake manifold takes in 3/4, couldn't you just use the old 3/8 to 3/4 adaptor, disconnect the 3/8 end and then buy a 3/8 to 3/8 barbed adaptor and have 3/8 lines going in and out of the catch can?
Thank you for another well done video. I enjoy following all of your videos because i just bought a 2011 Gen3 and found the HV fan inlet screen is missing. I will be watching your videos on how to access the HV battery and cleaning out the fan unit. Also I will be changing the ECVT, Radiator and Invertor fluid this weekend too. All by watching your channel. Thanks again.
Simple install: get under car, disconnect hose at PVC valve, place intake catch can hose to PVC valve, connect output hose to PVC hose with 3/8 double ended connect with hose clamps, and your done other than placing the can. Smart addition: drain valve on catch can and stainless steel "brillo-like" pad in catch can. After 10k miles you'll get 10 to 15 cc's of sludge in the can. Better to dump it then burn it in your intake manifold.
Tried it but was impossible to work with the hoses from underneath. But your idea of using the existing hose by cutting off the small end worked beautifully. Also the brillo pad was such a good idea that now it comes with the catch can. Thanks!
I'm planning on using a 3/8 x 3/8 barbed to barbed elbow/90deg connector like someone has done. That would allow one to keep the original pcv hose without cutting the small end. I'm questioning and thinking not to use the steel wool baffle it comes with because some people say it will eventually rust and parts of it will go into the intake.
@@elysianfields6350 good point. Finally doing this mod. Gonna use zip ties now and try to find someone to 3d print the bracket. At 302k 2013 and I got a 2 second stutter at cold start up. I hope it's not coolant leaking in and maybe PCV change will correct. EGR system, intake clean has not resolved it. Update: Replaced pcv valve, installed oil catch can, and cleaned the small port holes on intake with pipe brushes which I think that was probably the reason for the cold start stutter.
It might take a while, but those hose clamps are going to wear through that coolant hose and spring a leak. Also should have used a barbed to barbed 3/4" to 1/2" for the inlet into the air intake. However, this video was very helpful and I'll definitely be using it for my 2013 Prius V.
6,8,10,12,14,17,19,21mm these are the most common sizes that are used on all Toyota vehicles, for anybody that works on a Toyota they own should get at the least these size sockets and wrenches.
Great videos, thanks. I saw a comment on the Toyota GB/UK web page that said if you use 0-20 oil instead of 5-30, there is less splash into the PCV. They said that thicker oil is the cause of oil entering the PCV. Perhaps that is true for newer engines, but in my experience as engines age they tend to blow more oil through the PCV in any case. I've only done 43,000km in my P410 2017 Corolla Hybrid (Australia). I've been using 5-30 because of the heat in Brisbane, Australia, but I might try 0-20, after I've cleaned out the PCV and inlet to see if it has any oil in it yet - probably at 50,000km service.
@@reocam8918 You will need to remove the intake manifold to get to the place where you attach the can between the PCV valve and the intake manifold, it is too tight of a space to do the job without removing the intake manifold assembly.
Great video again. I will point out a small L shaped metal bracket found at any hardware store can be used to mount the catch can you provided a link to. It will mount in the same place.
I got all set up to install one just like this on my 2013 Prius 3. Guess what, there was absolutely no room for it between anywhere under the trunk. I wish I had found out before I got the hoses connected and routed over there. I felt really stupid. A shit load of work, but I was already in the process of cleaning the intake manifold and EGR cooler.
The oil catch cans I use come with nipples the same size as the outlet on the PCV valve and the intake inlet. I've added them without removing the he intake. I use a re-usable zip tie to fasten the can to the large orange high voltage wire bracket which makes my hoses much shorter.
Why didn't you run the larger-diameter hose all the way to the OCC and install the reducer there? Or even just install a larger-diameter connector into the OCC (many of them come with both small and large connectors)?
Yup. I'm thinking of the same thing. Intake is 3/4 and occ is 1/2. Better to use 3/4 hose and use reducer to 1/2 at the occ. Much more room to work on and easier for the whole process.
Successful install on 2013 plugin 302K miles. I used a 3/8 x 3/8 barbed to barbed elbow/90deg connector from Lowes and the 5 foot fuel line hose from amazon was just enough with a little slack left for both ways. So about 2.5 feet each way works. I kept the original pcv hose on the intake and moved the hose down right below the map sensor. I wasn't sure if I should put the hose up against the engine or down, but I chose to go down because concerned about the heat of the engine and I can also easily replace or keep an eye on the connection without removing intake manifold. I did not use the stringy steel wool baffle because concerned about it rusting before I would notice the rust starting. Maybe will put something better as others suggest but if the oil level is low when I change then not much of a concern I suppose.
Thanks for making this video. Since your installation, how's your car running? And how many time have you emptied out/cleaned your Oil Catch Can? Thanks.
What is your thought on installing the PVC valve outside the engine intake manifold assembly? So where the PVC valve is suppose to be, install a steel nipple and connect the end with 3/8 hose. After a short distance install the PVC valve. The ideas is that it'll be easier to access the PVC without disassembling the entire mainfold.
great video. i ordered an OCC but the link in your comment section goes to some blog will OCC pics, but no ordering info. I need a bracket for my gen 3-help!!
The OCC bracket was made using the 3d printer. The website is just the file for the bracket where you can use it to send to other people who does 3d printing to print the bracket.
Just installed mine the other day. I wanted to know if at all there would be any issue due to the catch can being higher in level to the PCV valve (potential oil to run back down into the valve due to gravity. Also too has anyone inspected the rubber hose from the valve to the catch can and if there is oil build of there that is significant. Thank you for this video btw. Because of you I was able to do everything you have done on your Prius. I truly felt like a mechanic because of you so thank you for that. It means a lot. 🙏🏽
What was you mpg before all of these maintenance DIYs and after? Mine has been at low 40s since I purchased at 90k miles. Changed spark plugs, engine oil, CVT oil, cleaned IM/EGR pipe. Later this month about to add the OCC, change PCV, clean EGR cooler, and change the coolants. Your videos help a lot!
Jordan, what item if any helped your mileage ? on 2014 with 155k I'm getting 41mpg around town (45+ on hwy so I suspect battery with 65% left thanks to Dr Prius app to be the main culprit as hwy miles seem good) and wondering what to check for. Prev owner had spark plugs changed (verified Bosh in there now)... not burning any oil that I can tell so far with 3k miles driven, so EGR cooler cleanup or manifold might not be needed, let alone a OCC. Might do it for the fun factor :) Ro Z, about to try sea foam next... gas and intake version (which smokes a lot - wonder why it does to catalytic converter ??) - how many miles and year ?
My 2010 with 88k runs much better since removing and cleaning the intake manifold - it had the typical pool of oil underneath the throttle body. I've never had any cold start or knocking issues. I also installed a catch can stealth to the front motor mount bracket. It's sad that these cars are showing up on craigslist with less than 150k with blown head gaskets - Several per week in the Bay Area alone.
were those 2010 specifically or any gen3 year ? I've just bought a '14 with 155k (also from Bay Area) and while I'm not seeing any oil burning (3k only) wondering if I should go through EGR coolant and manifold cleaning to see/prevent any issue. I know the intake was redesigned for 2012.... and 2010 piston oil eating fixed as well.
Well detailed video. I followed your video and installed OCC successfully. I ran my Prius on maintenance mode for almost an hour ( to check if it's still overheating intermittently due to weak water pump that I replaced with new water pump and that's been fixed ) but I noticed the hose that I connected from outlet of Oil catch can that goes into the intake manifold was completely flat due to high pressure. Do you think OCC might not be functioning as it supposed to or should I replace with the heavy duty hose ( thicker one) , like the one I got that connects from PCV valve to inlet of OCC. Do you think I need to get a vacuum hose which is thicker than the one I installed ( maybe I got radiator hose ) . Thank you for you reply.
Did I miss something? with the catch can do you not need to dump what collects in it? Also, do you not need to replace the gasket or seal the manifold when installing? Thanks for the Video
Yeah sorry, the person who used to make the bracket stopped making them. But if you can find the 3d print file, you can ask any 3d print user to print it for you.
Hi , there any time for me to have a smog check in California .. my question is I need to take out the oil catch can be for going to smog station? Or they will fail it because of that modification for inspection.. thanks
I’ve had it on ever since this video and every 2 years I take it to smog and they never fail me because of this mod. It doesn’t affect the vehicle performance so it’s ok to have it on. I live in California as well.
I understand there is a big problem with the 2010 through 2015 Prius's EGR system getting severely clogged. Does this help and prevent the EGR system from getting clogged ? Anyone ?
great video---I noticed that there was no intake manifold gasket?? or valve cover gasket? I've never worked on one...but bought a 2016 touring a few years back...and am looking to add catch can etc...
chicagomike6666 the gaskets are attached on their unit, we didn’t remove it or mess with it because we don’t want it to be forgotten when we put it back in.
Were you using heater hose for the oil catch can? I wasn't able to find 1/2 fuel line at any auto parts stores, only heater hoses. I was reading that you're not supposed to have oil touching that type of hose, so I'm a little conflicted about using it or not.
@@Senorlatulla The fuel filter is located on the fuel pump itself. They are designed to last the life of the car. Replacing it is possible, but would require dropping the fuel tank and removing the fuel pump. That is an insanely labor intensive process. I would not change it unless the fuel pump went bad.
Using a threaded end inside a rubber hose is a bad idea as its very difficult to seal off the valley of the threads well enough to prevent an air gap. You are probably going to end up with an air leak because of the threads.
Hi nutzaboutbolts. What kind of hose did you use for the 3/4", did you manage to find fuel line in that size, or fuel filler hose, PCV hose? Or heater hose? Seems tough to find anything in that size that 100% approved for fuel/oil exposure. And when you think about it: it's barely exposed, very short, and on the "clean" side of the OCC. Addendum: I've ordered the 3/4" ID size of this: CONTINENTAL PREMIUM AGRICULTURAL FARM TANK HOSE
@@NutzAboutBolts Thanks. i started and waned to initiated this project on my 2005 (260k miles) years back; it wrecked damage on muffler & CAT. Now I got a 2010 (244k Miles) that needs some loving. I accidentally found that OCC in wrapper from years back in basement last week- lol. Your vids are motivating me to get back at it.
I followed the link to the amazon listing for the 3/8' fuel hose but it comes up with a 1/4" fuel hose...is that correct?! I plan on doing this this weekend, I have a 2010 prius and was wondering why it has all these problems lately and everything people are describing are EXACTLY what is happening to my car.
Catches dirty oil vapors instead of recirculating it into the intake manifold. It over time will cause gunk build up on valves and could cause knock during startup. Catch cans are common practice in supercharged and turbo cars. It is just 1 more piece of insurance to keep your vehicle lasting
This gen of Prius is infamous for oil consumption issues. My 2011 is using about 2 whole quarts between changes. This is caused by one of two issues: bad piston rings (not hugely common, but can happen) or a failed PCV valve. When the pcv valve fails, it allows oil to get pushed from the block into the intake and burned. Changing the pcv will stop this, but if it fails, nothing stops the oil from getting into the intake before you notice the symptoms. The catch can does just that. You will still lose oil when the pcv fails, but at least it isn’t going into the intake. Crap design on Toyota’s part honestly.
@@SweetLou0523 Thanks for the explanation. Scotty Kilmer also has a video explaining this. As I was watching this video I decided it was WAY to complicated for me to even attempt. I'm not diyer.
We changed ours out less than 30k miles ago, if you haven’t changed it, you should since it’s rubber and it’ll become hard and brittle. Since you’re doing this, night as well tackle everything else around that area, i.e egr cooler, pipe, pcv etc etc
What you do to get better results is screw the PCV to the out of the catch can directly to the intake. This way you can just unscrew it and check it and clean it at oil changes
@@Tannnnman yes I screwed the PVC valve into the out of the can this way the oil can go back into the block and the PCV can be cleaned . I USE BARRYMANS B12 Chem tool
Thank you for your videos. They've helped a lot! I'm starting my intake manifold cleaning, egr cooler cleaning, replacing the pcv valve and installing a catch can. It will be a busy few days. My question is which side is the OUTPUT and which is the INPUT for the PCV valve? I imagine that the piece you attach the hose to is the OUTPUT on the PCV valve? And that would go to the INPUT for the OCC? Is this correct? Also, It's better to use silicone on the hoses instead of wd40. Thanks again!
Yes, the pcv is the output and the input is into the canister. We used WD-40 all the time and it always work, we don’t like the silicone because it leaves a residue when done but you can use it if you want.
That is what I figured. Better safe than sorry though! You need some 1/4 snap on tools! Makes getting into those tight spots easier! :) WD-40 eats rubber, not supposed to, but it does. But I imagine the hosed will need to be replaced before anything else. Thanks again.
Do you have a suggestion on a good bracket for this? I tried the link but doesn’t seem to have an option for purchase? Any help would be appreciated before I try to configure myself....
Check priuschat on the 3rd gen forum. I bought from a guy who 3D printed it. I think he stopped making them but maybe you can find someone who has the file to 3D print it out for you.
@@codywoodman9913 just replaced that valve in my Prius. It was blocked. You can see the valve at 8.05, you have only to unscrew it and replace. Costs about 30 on ebay
Very informative video. Since I got everything apart in the process of cleaning intake manifold and EGR cooler, this is the perfect timing to install OCC. So, can I know where did you buy those hoses. And can I find 1/2 hose that came with the kit at home depot ? Are the hoses we find at Home depot designed to stand the heat from the fumes? I really appreciate that information . I am going to install a long hose that's behind the intake ( so that I don't have to take off intake again when I add OCC next week. Thank you.
Every couple thousand miles depending on how much oil you catch. I would check after the 1st thousand miles to see how much is caught. Judge based on that
Do you have a company that makes the oil can brackets? I gave the 3d printer file to a friend and he told me that his plastics wont hold up to the heat.
Not sure about gen4 prius, but in gen 3, quick way to check is to take off the air filter assembly and look into the bottom of throttle body. In gen 3 prius, you can see pooling of oil there which immedietly meant that oil was pooling in from pcv valve and going to cylinders causing future issues.
I couldn't find that bracket but I'm going to try to make one out of plumber's pipe strapping and maybe run the strapping through a bike inner tube to cushion the can and keep it from scratching.
I did this install using fuel hoses that says "for fuel vapors and PCV applications but not fuel injection systems". But now there is a strong small of fuel and oil seeping out of the hoses. Does anybody know what to do about this?
Land Shass has your mpg drop off or staying strong? I ask because I have a 2013 with 120,000 miles and my mpg was around 55 all the time and now is 45. I got new tires new filter and always oil change on time. I also check tire pressure too.
Jon Bozzy , I do my mpg calculation at the gas pump (devid the number of miles driven from last tank top off by the number of gallons filled at that moment). I always get around 53 actual while car computer say 55). Some tire brands mess up the calculation, that's why I go by the pump math. Back to your question, yes the same mpg. I got rid of OEM tires Bridgestone Ecopia due to alignment issues. I replaced them with Michelen Energy Saver A/S, put around 95 K then I replaced them with Michelen Defender, at that time the Energy Saver A/S was discontinued. Prius needs a LRR tire (low rolling resistance) and drive style is a big factor, I drive like my grandma , and mostly country side roads (no stop n go and no wind resistance). Every once and a while I get mpg drop during storms or extreme cold weather.
As a previous owner I must interject. I have a 2010 Toyota Prius. There are no issues with my car supposedly. I have had new spark plugs and constant oil changes with 0 20. My car gets around 38 miles per gallon. I am happy to hear that. I would like to know that someone gets better miles per gallon than I do.
The PCV system runs some oily air back through the motor so this will see that oily air and hopefully catch most of the oil. It keeps the intake side of the motor cleaner.

The website is just the file for the bracket where you can use it to send to other people who does 3d printing to print the bracket.
Just installed mine the other day. I wanted to know if at all there would be any issue due to the catch can being higher in level to the PCV valve (potential oil to run back down into the valve due to gravity. Also too has anyone inspected the rubber hose from the valve to the catch can and if there is oil build of there that is significant. Thank you for this video btw. Because of you I was able to do everything you have done on your Prius. I truly felt like a mechanic because of you so thank you for that. It means a lot. 🙏🏽
I cant find the bracket for the catch can, how did you put the catch can in the car?
Have you seen any drop in the MPG?
Definitely (1/2 to 1/2 MNPT Male color) for the intake brass barb. Little botched by the bag color, it was red for the brand at my local store.
will this solve the knocking on a cold start?
According to Priuschat, yes. The guys on the forum solved this issue with this product.
What was you mpg before all of these maintenance DIYs and after?
Mine has been at low 40s since I purchased at 90k miles. Changed spark plugs, engine oil, CVT oil, cleaned IM/EGR pipe. Later this month about to add the OCC, change PCV, clean EGR cooler, and change the coolants. Your videos help a lot!
Jordan Ensminger I noticed 4mpg gains when using seafoam.......
Jordan, what item if any helped your mileage ? on 2014 with 155k I'm getting 41mpg around town (45+ on hwy so I suspect battery with 65% left thanks to Dr Prius app to be the main culprit as hwy miles seem good) and wondering what to check for. Prev owner had spark plugs changed (verified Bosh in there now)... not burning any oil that I can tell so far with 3k miles driven, so EGR cooler cleanup or manifold might not be needed, let alone a OCC. Might do it for the fun factor :)
Ro Z, about to try sea foam next... gas and intake version (which smokes a lot - wonder why it does to catalytic converter ??) - how many miles and year ?
@@alaind831 what is OCC?
@@Senorlatulla oil catch can
My 2010 with 88k runs much better since removing and cleaning the intake manifold - it had the typical pool of oil underneath the throttle body. I've never had any cold start or knocking issues. I also installed a catch can stealth to the front motor mount bracket. It's sad that these cars are showing up on craigslist with less than 150k with blown head gaskets - Several per week in the Bay Area alone.
were those 2010 specifically or any gen3 year ? I've just bought a '14 with 155k (also from Bay Area) and while I'm not seeing any oil burning (3k only) wondering if I should go through EGR coolant and manifold cleaning to see/prevent any issue. I know the intake was redesigned for 2012.... and 2010 piston oil eating fixed as well.
Well detailed video. I followed your video and installed OCC successfully. I ran my Prius on maintenance mode for almost an hour ( to check if it's still overheating intermittently due to weak water pump that I replaced with new water pump and that's been fixed ) but I noticed the hose that I connected from outlet of Oil catch can that goes into the intake manifold was completely flat due to high pressure. Do you think OCC might not be functioning as it supposed to or should I replace with the heavy duty hose ( thicker one) , like the one I got that connects from PCV valve to inlet of OCC. Do you think I need to get a vacuum hose which is thicker than the one I installed ( maybe I got radiator hose ) . Thank you for you reply.
Hi Kumar are you in washington DC area.
Did I miss something? with the catch can do you not need to dump what collects in it? Also, do you not need to replace the gasket or seal the manifold when installing? Thanks for the Video
Yes I dump the oil in the catch can every oil change, no I didn’t put new gasket on the intake manifold
Great video...I know this is an older video---but where would you mount a catch can on a 2016 prius...? Any advice greatly appreciated.
Great and helpful video! Thank you! I saw the link you left for the bracket, but I don’t see how to purchase the bracket 🤔
Yeah sorry, the person who used to make the bracket stopped making them. But if you can find the 3d print file, you can ask any 3d print user to print it for you.
@@NutzAboutBolts Oh! Great idea! Thank You 🙂👍
Hi , there any time for me to have a smog check in California .. my question is I need to take out the oil catch can be for going to smog station? Or they will fail it because of that modification for inspection.. thanks
I’ve had it on ever since this video and every 2 years I take it to smog and they never fail me because of this mod. It doesn’t affect the vehicle performance so it’s ok to have it on. I live in California as well.
@@NutzAboutBolts thanks
Any smog station you recommend on Orange County are
@@bulco22no sorry, I’m up north. I’m sure Yelp would help and shop around for the cheapest one. That’s what I did.
@@NutzAboutBolts thanks Again great video
I understand there is a big problem with the 2010 through 2015 Prius's EGR system getting severely clogged.
Does this help and prevent the EGR system from getting clogged ?
Anyone ?
Yes.
Did you read the one-star reviews about the can?
How do you test the can for effectiveness?
great video---I noticed that there was no intake manifold gasket?? or valve cover gasket? I've never worked on one...but bought a 2016 touring a few years back...and am looking to add catch can etc...
chicagomike6666 the gaskets are attached on their unit, we didn’t remove it or mess with it because we don’t want it to be forgotten when we put it back in.
Daniel, on Prius Chat, no longer sells that bracket. I have to modify one myself.
Just set mine up and use two zip ties in the same location. Seems to work fine.
Hello. What about in cold winter? I mean, gas condenser from crankcase can freeze in the long catch can hoses. Or not?
Good question.... Any answers?
I wondered this as well. There's a lot of hose for moisture buildup.
Were you using heater hose for the oil catch can? I wasn't able to find 1/2 fuel line at any auto parts stores, only heater hoses. I was reading that you're not supposed to have oil touching that type of hose, so I'm a little conflicted about using it or not.
Go to Home Depot, they have the oil hose by the foot and you just have to get it cut.
@@NutzAboutBolts Sweet thanks for your reply
Can you do a video replacing the fuel filter on the Prius?? Figured it would make sense going along with all the maintenance vids on the vehicle
Esah305 220k and never changed the fuel filter
@@Grahams-Grass 11 months later, for all those who truly wish to baby their Prius, would you now change the fuel filter?
@@Senorlatulla The fuel filter is located on the fuel pump itself. They are designed to last the life of the car. Replacing it is possible, but would require dropping the fuel tank and removing the fuel pump. That is an insanely labor intensive process. I would not change it unless the fuel pump went bad.
@@jeffreycastles in the prius the fuel pump is under the back seat, ao, you can just remove the seat and chang it, if you want.
Using a threaded end inside a rubber hose is a bad idea as its very difficult to seal off the valley of the threads well enough to prevent an air gap. You are probably going to end up with an air leak because of the threads.
Where can i buy the bracket for the catch can? Clicked on the link but dont find how to buy it on there.
perfect - thanks for your DIY
I wish the engine bay on my 2011 looked this clean! Geez! New Jersey just eats cars.
Awesome install video.
Thanks for sharing.
Hi nutzaboutbolts. What kind of hose did you use for the 3/4", did you manage to find fuel line in that size, or fuel filler hose, PCV hose? Or heater hose? Seems tough to find anything in that size that 100% approved for fuel/oil exposure. And when you think about it: it's barely exposed, very short, and on the "clean" side of the OCC.
Addendum: I've ordered the 3/4" ID size of this:
CONTINENTAL PREMIUM AGRICULTURAL FARM TANK HOSE
Hows your update now. Works well holding up? Catching any oil excess? Thanks.
Sung N working well, catching lots of bypass fluids in the catch can.
@@NutzAboutBolts Thanks. i started and waned to initiated this project on my 2005 (260k miles) years back; it wrecked damage on muffler & CAT. Now I got a 2010 (244k Miles) that needs some loving. I accidentally found that OCC in wrapper from years back in basement last week- lol. Your vids are motivating me to get back at it.
Is it working your EGR VALVE AND PIPES ARE NO LONGER DIRTY
Working fine
It seems like since the old hose is not used any more, why not just cut it in half and use it as "adapter" for two other hose leading to catch can?
Is the reason for this and cleaning oil in the intake manifold all due to worn rings?
Yes. Worn rings produce blowby
I mounted my first oil catch can that way and the hood hit the dipstick and loosened it which caused a vacuum leak.
just wondering, better to have a longer fitting hose for a permanent install?
I followed the link to the amazon listing for the 3/8' fuel hose but it comes up with a 1/4" fuel hose...is that correct?! I plan on doing this this weekend, I have a 2010 prius and was wondering why it has all these problems lately and everything people are describing are EXACTLY what is happening to my car.
John Johnson you’re right, I’ll have to remove the link for it. You can buy those fuel hose at Home Depot or auto parts store.
Can anyone say what this catch can is for and purpose? Also what symptoms were on the prius before the install...
Catches dirty oil vapors instead of recirculating it into the intake manifold. It over time will cause gunk build up on valves and could cause knock during startup. Catch cans are common practice in supercharged and turbo cars. It is just 1 more piece of insurance to keep your vehicle lasting
This gen of Prius is infamous for oil consumption issues. My 2011 is using about 2 whole quarts between changes. This is caused by one of two issues: bad piston rings (not hugely common, but can happen) or a failed PCV valve. When the pcv valve fails, it allows oil to get pushed from the block into the intake and burned. Changing the pcv will stop this, but if it fails, nothing stops the oil from getting into the intake before you notice the symptoms. The catch can does just that. You will still lose oil when the pcv fails, but at least it isn’t going into the intake. Crap design on Toyota’s part honestly.
@@SweetLou0523 Thanks for the explanation. Scotty Kilmer also has a video explaining this. As I was watching this video I decided it was WAY to complicated for me to even attempt. I'm not diyer.
Is it okay to reuse the inlet manifold gasket ?
Good how to, thanks, Tony....
We changed ours out less than 30k miles ago, if you haven’t changed it, you should since it’s rubber and it’ll become hard and brittle. Since you’re doing this, night as well tackle everything else around that area, i.e egr cooler, pipe, pcv etc etc
@@NutzAboutBolts Hi! How many gaskets are there for the inlet manifold? Is it two?
What you do to get better results is screw the PCV to the out of the catch can directly to the intake. This way you can just unscrew it and check it and clean it at oil changes
Can you really do this? It sounds way to good to be true
@@Tannnnman yes I screwed the PVC valve into the out of the can this way the oil can go back into the block and the PCV can be cleaned . I USE BARRYMANS B12 Chem tool
Thank you for your videos. They've helped a lot! I'm starting my intake manifold cleaning, egr cooler cleaning, replacing the pcv valve and installing a catch can. It will be a busy few days. My question is which side is the OUTPUT and which is the INPUT for the PCV valve? I imagine that the piece you attach the hose to is the OUTPUT on the PCV valve? And that would go to the INPUT for the OCC? Is this correct?
Also, It's better to use silicone on the hoses instead of wd40. Thanks again!
Yes, the pcv is the output and the input is into the canister. We used WD-40 all the time and it always work, we don’t like the silicone because it leaves a residue when done but you can use it if you want.
That is what I figured. Better safe than sorry though! You need some 1/4 snap on tools! Makes getting into those tight spots easier! :) WD-40 eats rubber, not supposed to, but it does. But I imagine the hosed will need to be replaced before anything else. Thanks again.
Snap ones expensive. As for WD-40 eating rubbers, never heard of it but I will watch out for the hose. It can sustain oil and brake clean.
I have SnapOn tools from 1985! STILL using. WELL worth the money!
OR, I could sell them and retire at 91!!!
Yeah, theyre high quality tools. I have some and also Matco tools.
What are the hose sizes? You have three hose size in the description. So it’s 1/2 or 3/4 or 3/8 ?
wondering where can i find the catch can bracket
I made simple bracket..
What State are you in? Im in Las Vegas. Would you travel to work on a Prius if paid for your time?
Sorry, we only do tutorial videos... I’m sure there’s plenty of great mechanics out there who works on Prius.
What size are the fittings on the oil catch can? Mine doesnt have any fittings on it
is this modification really worth it? how much oil comes outta there?
Yes for gen3 it's going to save your engine from HG failure and possibly engine failure.
Do you have a suggestion on a good bracket for this? I tried the link but doesn’t seem to have an option for purchase? Any help would be appreciated before I try to configure myself....
Check priuschat on the 3rd gen forum. I bought from a guy who 3D printed it. I think he stopped making them but maybe you can find someone who has the file to 3D print it out for you.
what is the name of the valve that you're describing at ~8:05? I can't find anything about it anywhere
I'snt it the Pcv valve? You can see it just close to his hands.
@@raffaellorelaxingvideo nah it's the one where he says "we disconnected this switching valve here" and taps it
@@codywoodman9913 just replaced that valve in my Prius. It was blocked. You can see the valve at 8.05, you have only to unscrew it and replace. Costs about 30 on ebay
Thanks

For a few minutes there you could have been the Bob Ross of auto repair.
Hey, that rhymed...
🤣🤣 we get that a lot 🧑🎨
Very informative video. Since I got everything apart in the process of cleaning intake manifold and EGR cooler, this is the perfect timing to install OCC. So, can I know where did you buy those hoses. And can I find 1/2 hose that came with the kit at home depot ? Are the hoses we find at Home depot designed to stand the heat from the fumes? I really appreciate that information . I am going to install a long hose that's behind the intake ( so that I don't have to take off intake again when I add OCC next week. Thank you.
Yeah you can find those hose size at home depot or any auto stores. They’re design to withstand oil going through it and heat.
Will installing this throw codes or not pass smog check in California?
Nope, no code for me, and the smog tech smog with it on. He didn’t say it was an issue when I went to smog my car.
Is this legal in California. I just saw that I need to get smoggy this year. Can some one with this application tell me if this is legal
Yes, it’s legal, I had my vehicle smog checked with it and the tech didn’t say anything.
@@NutzAboutBolts thank you for all the support
Hi, I found the one has a small filter on top, you think that one works Better, or without the filter breather is just fine?
I think someone said dont use the filter or prius thinks you have a vacuum leak. Keep it a closed system.
I got a 2014 C2 prius. How often does the oil catch can get cleaned or swapped out?
Hey Eddie.... did you find out?
Every couple thousand miles depending on how much oil you catch. I would check after the 1st thousand miles to see how much is caught. Judge based on that
Thanks great video!
Do you have a company that makes the oil can brackets? I gave the 3d printer file to a friend and he told me that his plastics wont hold up to the heat.
I don’t, the guy that was supposed to 3d print it stopped doing it I think… you can try the link I posted up and see if he still does it or not
Does this help reduce oil consumption?
I think no. It just help prevent from the oil and some other substances to meet inside the Intake Manifold which later makes a pile of goo.
Any update on how helpful the catch can setup is?
We did an updated video.
Does anyone here knows if a high mileage 2012 toyota prius C burn oil?
What's the catch?
@Herbert Wingfield Oil have to ask you to stop these jokes.
Any long term update since having this installed?
Still running strong with this in. No issues at all
I don't have a 3d printer. How do I go about getting someone to 3d print the catch can bracket?
The link in the description box, but not sure if he still does it or not.
Will the hose collapse from vacuum of intake?
@@ibezag0 no, it’s made to withstand that and oil. It’s pretty thick
@@NutzAboutBolts thank you
What oil catch can do you buy for a 2014 Prius
It’s amzn.to/2KZ72kt
Is it necessary to add an oil catch can to 2019 Prius (4th gen)? I yes, at what mileage to add occ? Thanks
Not sure about gen4 prius, but in gen 3, quick way to check is to take off the air filter assembly and look into the bottom of throttle body. In gen 3 prius, you can see pooling of oil there which immedietly meant that oil was pooling in from pcv valve and going to cylinders causing future issues.
Where did you buy the catch can any link pls
Where did you bought white brackett?
the white bracket was printed with a 3D printer.... it isnt sold
I couldn't find that bracket but I'm going to try to make one out of plumber's pipe strapping and maybe run the strapping through a bike inner tube to cushion the can and keep it from scratching.
Where did you get the 3/4 hose in your hand at minute 7:24. Did it come with the oil catch can kit?
You can buy them at Home Depot. Make sure it’s oil compatible or else the hose will collapse under pressure and heat.
@@NutzAboutBolts and it’s the rubber one correct?
@@Jeremy-vz9gr yes, the black one
Did you 3d print the bracket or how did you buy the bracket from that website
The guy 3d print it for me. He used to sell it, but I guess not anymore?🤷🏽♂️
is it illegal to install a catch can in California?
Nope, went to smog with it and the tech didn’t say anything
Where does the hose from PCV gets connected? To the IN or the OUT of the oil catch can.
Inlet side of the catch can.
@@SEAW1NG thank u great help
My car idling now after installing oil catch can. I also sprayed the air flow sensor . Why is it idling?? Please help
I'm considering doing this. Did you find out why it's idling?
If I didn't install this, what can happen??
You get a lot of oil pooling behind the throttle body
@@NutzAboutBolts but this is bad? Mine I am running like this about couple thousand miles already
@@John2022-i2q just more carbon build up and oil from it. Some people don’t install it. Not sure how their vehicles are though. Up to you.
All that work just to get to the pcv valve
I would've cut that PCV hose and connected cutoff to new hose.
how often rhis will fill up of oil? How to remove the oil?
You remove the can, the bottom unscrews, then you dump the oil out.
that OCC is rubbished with a steel wall will damage your engine gasket and cause an oil leak.
So where and how do I get that mounting bracket? Thanks
I bought it from a guy that used to sell it on priuschat, he has the 3D print file on thingverse.com that you can ask a 3D printer to print for you.
My man, why didn't you just get some 3/8" hose and a 3/8 to 3/8 barb. You could have just cut the existing and used a coupler.
Trying to keep the oem hose.
Why you need to instanl this oil cache can?
Touch Tr oil gets into the intake this will reduce it and keep your engine cleaner
Where did you buy the hoses ?
Autozone, oreilly or napa auto store
I did this install using fuel hoses that says "for fuel vapors and PCV applications but not fuel injection systems". But now there is a strong small of fuel and oil seeping out of the hoses. Does anybody know what to do about this?
Probably have a leak somewhere
@@rj.parker 😂
As a Prius owner, I wonder why a perfect car needs such a thing? (3rd gen 2013 with 200K miles with not a single issue)
Land Shass has your mpg drop off or staying strong? I ask because I have a 2013 with 120,000 miles and my mpg was around 55 all the time and now is 45. I got new tires new filter and always oil change on time. I also check tire pressure too.
Jon Bozzy , I do my mpg calculation at the gas pump (devid the number of miles driven from last tank top off by the number of gallons filled at that moment).
I always get around 53 actual while car computer say 55). Some tire brands mess up the calculation, that's why I go by the pump math.
Back to your question, yes the same mpg. I got rid of OEM tires Bridgestone Ecopia due to alignment issues. I replaced them with Michelen Energy Saver A/S, put around 95 K then I replaced them with Michelen Defender, at that time the Energy Saver A/S was discontinued. Prius needs a LRR tire (low rolling resistance) and drive style is a big factor, I drive like my grandma , and mostly country side roads (no stop n go and no wind resistance).
Every once and a while I get mpg drop during storms or extreme cold weather.
Jon Bozzy You can go to the dealer to check the health of the hybrid system. If the big battery is getting bad you can fix it cheaply.
Jon Bozzy make sure your using a good quality oil .
As a previous owner I must interject. I have a 2010 Toyota Prius. There are no issues with my car supposedly. I have had new spark plugs and constant oil changes with 0 20. My car gets around 38 miles per gallon. I am happy to hear that. I would like to know that someone gets better miles per gallon than I do.
What is the benefits of installing this
The PCV system runs some oily air back through the motor so this will see that oily air and hopefully catch most of the oil. It keeps the intake side of the motor cleaner.
@@dyoel182 and because the oil isn't burnt anymore it's not clogging up the EGR-system
