How to Install an Oil Catch Can Into Your Car 

As a 20 year old with an xterra who wants to learn more about cars and the xterra itself, I thank you for your videos

Excellent tutorial! I have the same oil catch can, only black. I have installed mine right at the PCV inlet of the intake. This way I have minimized the length of tubing going from and to the can. Anyway, the amount of crap collected in the can makes it a mandatory upgrade for this car, IMO. I like a little dipstick. In fact, you can remove of the oil/water with the syringe w/o unscrewing the bottom cap. Please do a follow up video during your next oil change.

Awesome video man. As usual, very informative and educational. Keep up the awesome work!

Brooo I thought you have a twin in the last seconds. TF. Nice editing really helpful.

Thanks so much man. I’ve needed a few ideas on how to tidy up the original can install. This vid is money!

I really appreciate your videos - thank you for taking the time to share this work.

Just installed the catch can on my 2017 Pro4X . Followed your video and installation wasn’t that bad. Good job, thanks. Step by step really helped !👍

4:00 that’s where the recirculating pump goes for rear automatic hvac. My pathfinder has one so I’m trying to figure out where I want to mount the catch can now. Btw thanks for your videos! I’m going to be replacing my timing chain shoes using your video as a guide this spring.

Finally! Been looking for a good video for the xterra.

mounting location and that bracket idea is awesome if you have thosse threads, my pro4x does not. that mounting area is the best option though

Its so easy and helpful installing the oil catch can I will do it for my car

awesome video man super helpful.

Took me 1h20m start to finish including prep, cleanup, and making a bracket. Good practice for my upcoming IMS install and spark plugs once the parts land. A 5"x5" T bracket ($3 from Home Depot) works pretty well. Bracket is zinc so it drills out pretty easily. Bolt spacing on the X is 9cm. I added about 4mm of washers - a neoprene one against the firewall then nylon - behind the bracket to help it rest better. Time will tell if they can withstand the temps. 7' of fuel line will leave you some working room. If you absolutely can't get that clamp off the back of the engine you can consider using a ⅜ ID barbed coupler to just extend it to the can. Thanks for keeping my Xterra on the road, Ryan!

I finally got the catch can installed, similar to the way you did it. Only I'm confused, there was another video on same nissan truck but he put hoses opposite way. I wish my catch can could have come with instructions instead of second guessing. Thanks for the video though, you helped me out a lot.

... I bought the Same catch can.Your video was Very helpful !!

Excellent explanation!

Good animation to explain. Thanks

Another great video 👍

great video! my only thing was if you use lock nuts like you do you should maybe do a video on the differance. VERY GOODd tip btw!

Nice clear explanation. Great job. 👍

Very well described

Please update us regarding the quantity of fluids your finding in your catch can and how often you need to drain it. In addition, an instructional video for replacing a pcv valve may benefit those which visit your channel.

I made my on catch can for my 2003 Camry. I bought 24 oz aluminum drink tumbler made for hot and cold drinks. It came with a screw on lid with a rubber o ring seal and a hole for a straw. Paid five bucks for it at a thrift store minus the straw. I installed a small drain valve in the side near the bottom, used the straw hole for the return line fitting and installed the inlet line about a 1/3 of the way down from the top. Since the tumbler got smaller from top to bottom i was able to install a baffle just above the inlet line. With the baffle above the inlet any oil mist stays in the can and allows the vapor to recirculate. With Harleys we install a filter on the end of the hose and vent it to the atmosphere. Recirculating it back through a car engine is bad enough but with a Harley the carbon will build up quick in the chambers and on the valves. It builds up in the heads on a car because the air fuel mixture from the car doesn't burn hot enough to burn it out and keep it clean. Unless you are using an additive in the fuel on regular intervals. Btw way mine is located up front down low beneath the headlite and battery. Easy to open the drain when i change oil. Great video that will help out a lot of people and that color blue is my favorite color too👍

Amazing, thanks

Great video as always! Thanks Ry. Will be using the same catch can (from your amazon link) to do mine sometime soon. :)) Not a huge fan of where you mounted your can lol... maybe I will see what other things I can fab up.

Ry great video!!

This catch can works well. You can also insert some stainless stool wool into the can (the thicker kind and not the ultra thin kind) to enhance the baffling effect. In doing so, it improves the functionality of the oil catch can and catches more oil overall. Great video dude.

Best vid on Catch Can Install on youtube.

Any more videos for the audi tt, thinking about picking one up and you have the most detailed videos for repair on the gt. Thanks

RTCG is a BAD ASS!!!!!

So well explained for the average Joe 👊🤠

On my 2006 Pathfinder, that mounting spot you chose is where a small coolant pump is mounted for the rear heat. It's routed over too the passenger side and goes down the firewall and goes towards the rear. Thought you had asked about it in the video.

Commitment issues...lol. Good job on the video.

Seems like a passenger side install would have been simpler and possibly more effective. I’ve been wondering if a second can for the driver side bank that feeds to the intake plenitude on the tube. I’ve noticed there’s a significant amount of oil there as well. Though it seems the pcv valve sends the oil to the right bank cylinders. The left side of the lower intake manifold was mostly dry and shiny while the right side had a significant film. The spark plugs after 100k miles also showed a history of light oil spray ect.

Good use of mounting. Just a couple of minor comments. Use thread lock or lock washers on the nuts re-attaching the can bracket because they can vibrate out. Also, put a washer on the first spacing bolt under your bracket. This will sandwich the big bracket holes between two washers for better distributed force so the bolt won’t wear through the hole, and it will be more secure.

Thanks

Few notes if you want to do it: 1. Remove the hood or you will be banging your head on it plus you get better access and view of the hose 2. The electrical loom can be removed but there is a small tab inside it and you need to use a small flat screw driver to lift it then pull 3. Disconnect the grey electrical plug to get better access 4. Use silicon lubricant on the inside of the tube before inserting it, those plastic inlets can be fragile. Did mine today and iI had to fight with the outlet from the PCV but finally got it off, some blood was spilled.

So I tried for as long as my patience allowed, but I could not remove the factory hose that connected the pcv to the air box. I gave up and remembered that I had vacuum connectors from a previous project so I used those to connect the IN from the can to the existing pcv valve and then just connected the OUT to the air box. Thoughts?

Fair play thanks .

How would you know if this is something that needs to be done yo your car?

Excellent instructional vid. Will this work on Frontier too? Im curious if location has room to undo the catch can bottom to drain the oil ?

Im installing one of these on a 2006 honda accord v6 the pcv valve doesnt have a hose on it it is there another place i can run the hoses to?

I have a 2015 Pro-4X - those studs are not present, so I'll have to drill holes into the firewall. Nice idea for the bracket - gonna copy that :)

My intake port was actually a bigger size. My stock pcv line had 2 size IDs on between the ends. I had to heat up the one end with a hair dryer and force is over the nozzel. Its never going to come off again lol.

Ry the the hose you disconnect first it’s that the out let for that side for the catch can ?? Or in let

I installed the same type of catch can last week in my Navara D40. I used heater hose 5/8in at the end that looks same size of my original hose. I will see how it goes.

Thanks you very much sir

My nav has 16mm diameter ports for the crank case and 16mm on the turbo. The catch can only came with a max of 14mm. Not so easy to find the right hosing.

Hi, How were the results using the catch can? thx!

Hey man, thanks so much for the very informative videos. You have really helped me give my 05 Xterra a longer life. I saw this video a while back, and am back to it cause I wanted to ask you about the oil catch an, seems like you've had it for a while. Do you have any new input, do you feel that it was worth it? I am waiting for mine, bit wanted a last minute input of if you feel it works. Thanks again. All your videos are awesome.

Great Job Ry. I'll do with mine pretty soon. Thanks

Heya mate, looks like I bought the same catch can on ebay. Wondering where does the filter it came mount up to?

Ry, I know this video is from a few years ago but the first link leads only to Amazon it doesn’t lead to the nuts used on the firewall studs. What size are those nuts? I ask so I don’t have to do the purchase and return, trial and error, at Home Depot.

I have a question. Can I install this on a ford escape 2013? I saw a video but the guy used a can with 3 hoses.

Little tip, nextime where theres oil or petroleum based fluids , use the piml teflon/plummers tape. Great job... Ill do this to my frontier :)

Can you do a video showing how to install keyless entry for all doors including the hatch in an Xterra? Your videos are super detailed and I'm struggling! Lol

Whoes that other guy at the end of the video 😁 there is 2 of you looking at the engine bay in the same time 😄

Great Great video

Good job 🤔.

I have a question about catch cans, are they mainly for GDI engines only,or are they good for about any vehicle? And do they actually work? Thanks for the helpful video

Hi mate Its too hard to Install it into peugeot 807 2.0 hdi 2009 Can you please help Thank you

Can you elaborate on that second larger hose that goes into the stock "oil trap" on the air box? How does that differ from the PCV in function?

Can I do this to a V6 3.3L VVT Lexus engine with 220k miles? TIA

Ok, now it has been almost two years. Have you seen enough oil in the catch can that you think it is really worth it? Noticed any other changes or improvements?

Great video! One question, what dud you do with the now open ports that aren't going through the catch can? It would appear there are now two open ports after the instal.

So, I must have an even more base model than you! I don't have those studs! HAHA wondering if there might be another way to add them in!

hi there, any follow up on the performance of the catch can?

What?! There’s two of you? Am I drinking too many beers?

Where did you get that bracket to attach to the firewall area?

I cannot find pcv valve and catch can of my volvo 740 in spain

Excellent, what is MIL at end of video you said, MIL

Should have replaced the pvc valve too while your in the back engine twisting n urning. Good nice vid.

Good job with the help of your twin brother!🤣✌️

Ry, did you leave off the nut size for the existing studs? "Nuts for the studs what are already in the engine bay: ______"

I’ve noticed that many cars will have this hose really short..and lot of people are running catch can with really long hose, will that make a bad impact on our engine ?? Also what’s the fittings size and how they’re called ? I appreciate the video..many people won’t go in details telling you the hose diameter or fitting, mine came with some 6an and 8an and I don’t really know how to set those up!! It’s easier for me to buy your same fittings with same hose and put some clamps ! TIA.

My 2018 pro4x doesn’t have those studs you mounted the bracket to

I put it on my car, i start it emiting too much smoke is that normal?

What about the valve cover breather

Just wondering if I'd need to fit an oil catch can to my fiesta mk6? I'm replacing the stock air box and I don't want the crankcase breather hose hanging about doing nothing so I guess it could run to a catch can

How often do u have to empty it?

What did you do with the air filter that came with it?

What do you know about breather tanks? Same thing but with a filtered vent on top

does this work as well as a provent 200 type oil catch tank?

Hey Ry any tips to repair catalytic converter for my 2005 Xterra or anyone here got any tips

So does this Nissan of yours have 2 catch cans or one ?

Do you installed with the PCV valve or delete it?

Where's ur check valve u want to install one to prevent back fire into the crankcase

did anyone ever find out what those studs are for? I have a 2006 offroad and i also have those studs.

What is the benefit of this and is it used for all engines

You installed this some time ago. Have you noticed oil in it? Would you still recommend this mod, given what you've seen?

what size arethose nuts that goes on the firewall studs?

You add stainless steel wool in your can?

Does it need to be in that spot ?? Or can it be mounted by the intake with longer hose???

Did you use the O-rings that came with the kit?

Why didn't Nissan do a recall to have this added or at least alert customers to this issue? I'm going to order this kit for my 2014 Xterra.

Thanks.... its the same install for Nissan frontier 4.0 V6 engine. You must have rats or mice tearing your insulation from the hood.

What did you mean by “the MIL is off?”

if its damaged beyond repair how can you repair it????

How many miles do you have on your x?

Couldn't u just use regular vaccum hose instead of fuel hose?
