I am an aircraft mechanic and some have a similar air/oil separator. The difference is the drain plug on bottom is actually a nipple or fitting which has a hose connecting it to the crankcase so oil drains back to the sump. It would be easy enough to do since you have the pipe plug at the bottom of your fill tube. You could remove plug and install a 90 degree fitting and plump the catch can directly to it.

[@SomebodyInTX111]

Plumb. Sorry misspelled.

[@HillbillyOffroading]

Mr. Christopher this is literally the best mod you could possibly do to a mud mower.

[@NicksGarageDoorService]

I think you may have forgotten one thing: Gravity. Since you mounted the catch can inlet so high, I think it would take either high pressure from the PCV or a failed PCV valve to collect much oil in the catch can. You may want to think about lowering the can down...

[@JunkStarBuilds]

I literally looked at that same one today..several on the market and all under 20$. A must have if you add a performance air intake adapter

[@Fearlessfront]

yea! I think it'll do the trick

[@PaulsPlace]

Really neat mod there. Great idea. Cant wait for the carb upgrade!

[@WeldstarCreations]

Nice install. The Murray has evolved into quite a machine.

[@vtownboxingfan]

Great info in your video also very clear and concise ... thanks for the upload.

[@tayb504]

I used a spare plastic mightyvac brake bleeder container as my catch can on a Honda ch80 4poke scooter. lid has a rubber seal and is air tight, as well as an inlet and outlet ports built into the lid. works superb.

[@prancstaman]

Nice setup. I can see it workin. But you know you have to make a video on you testin it out with another couple hot laps now. Love the sound of that thing wining out.

[@Mosolarfan]

plumb the catch can drain with a shut off down to the engine block drain so when you change oil, just hit the valve and drain the can too. also could drain the can back into the block that way.

[@turtle2448thomas]

Wouldn't the can be too high causing oil to fight gravity? I know small engines can't produce that much vacuum

[@ThunderDivine]

My thoughts too.

[@spencerstroh2084]

Matt_R probably not

[@elmermorris8043]

That would be a good thing that way the oil will go back into the motor were it belongs

[@paparitz1]

You did a good weld job - can't see melt area on cover. I believe the input line will fill before oil gets to canister & flaw purpose.

[@TheTractorboy828]

I put this mod on my mudder and it makes me feel better about oil not getting in the intake

[@albertsewell878]

Looks good! Oh and don't worry about being higher than port,, whole objective is not go in carb,, all that will happen is catch can will catch less

[@MrTheHillfolk]

It doesn't look too bad. If anything , bigger is better on pcv hoses. I'd try and get something that's like 1/2id hose, changing those fittings on the tank would suck tho. Ya just want a large area for the oil and blowby air to seperate,and naturally oil is heavier than air so it'll usually fall to the bottom inside a large container

[@mw3898]

Sweet mods...seemingly effortless install! You should do an update vid after some nice romping and show how much oil you end up draining out, if any.

[@UnitCrane514]

I see a major flaw in that design. Its higher than the carb so the oil has to travel uphill to go the can, which it wont do because that engine doesn't produce enough vacuum. You don't need to run that blow by air back into the carburetor. Close off the port in the intake and run the crank case side of the hose into a sealed tin can with 3 or 4 1/16" holes in the bottom. Stick a filter element in the can so junk cant go up through the holes in the bottom and your golden. Its total loss and will just drip on the ground...but so what, its a tractor. 2 stroke Detroit Diesels have a breather like this (just a pipe no can or filter on the end), its a fail proof simple design.

[@Fearlessfront]

Thats all fine and good on a semi-truck, but occasionally go under water (and sometimes stall) and that would backfeed the system with moisture... The whole point here was to build a sealed system that doesn't leak oil all over the environment. I'm not really concerned about the oil not making it to the catch can at all, as long as it doesn't make it to my carb i'm happy.

[@SomebodyInTX111]

Fearlessfront I agree that the can should be at or below the pcv port on the engine.

[@taylormorris3926]

I was thanking the same thing

[@Fearlessfront]

tested yesterday, and it has no problem reaching the can. It works great!

[@luigiprovencher]

I thought the same thing about the oil having to travel up hill but it you say that it works then I guess it works.

[@starpuss]

Looks good! I picked one up for my Vtwin last week and I paid a little more , But I wanted the one with the air filter on top.

[@brendenlohmann4213]

You ever gonna starts up on the lt500 again

[@starpuss]

Brenden Lohmann I was working on it last week , Needs LOTS of work

[@brendenlohmann4213]

Do they make replacement frames for the

[@1997cr80r]

On Cat semi engines they have one of those with a hose connected to the drain and the hose goes back to the crank case so you never have to empty it. I think with the way you have it higher than the carb it won't pump the oil up there but it will kinda sit in the line and gurgle on it. Its all theory just try it out on the track again

[@rex4x4]

Lovin the blingieness . Soon your gonna have a computer on it lol .

[@rtabish]

nice...and looks pretty industrial [in a good way]. for a couple bucks, you could get some braided steel sleeves to slide over the lines. would be helpful in case the lines are rubbing someplace, but would look cool, too. looking at this, it is very similar to the oil catch system on some of the older motorcycles i have ridden. this would also give you some idea how much moisture is being trapped in your crankcase, since removing that moisture is one of the reasons for having a PCV system on an engine. definitely a must-have if you do a lot of leaning on curves, or just happen to dump what-ever 4-stroke bike or ATV you happen to be on....not that i have EVER dumped a bike. LOL

[@Fearlessfront]

very true, I ran it yesterday and there was tons of condensation running into the can.

[@PaulieDetmurds]

Just trying to watch all your videos, and this Sir is a very nice upgrade as well as some good "preventive medicine"! NICE!

[@peterravesi3439]

You should put speakers and a head unit on one of your tractors to get the maximum fun out of one of them

[@krromas1966]

I made a catch can with a radiator flush connection that goes in your heater hose and an old R 12 1 pound of freon cans i had milk on my oil fillcap dipstick on a old Ford 250 6 cylinder I have a cracked head gasket vet care of most of the problem inside of 6 weeks I got just about three quarters of a gallon of boister out.of my crankcase I drove a 1985 Mustang for 3 more years and put on about 52 thousand more miles

[@redforman27715]

Love the mods on ur mower Thanks for opening another way to cheap fun for me

[@NotMeeither]

The hose that came with the catch can will work MUCH better than what You used ! It is not water line, it is high pressure silicone line!!

[@kathyholland1216]

Thanks for your videos. I love to watch them.

[@iampkhacker]

dunno about one on that mud mower, but putting together alot of turbo cars they help alot. pretty much have to run a catch can on em, but i'm sure it'd help with the mud mower.

[@MrTheHillfolk]

It's being used beyond it's designed purposes. Cornering forces and over revving beyond stock have added up to cause a problem. I still think a little deflector on the inside of the rocker box cover would also help so the splash doesn't hit that disc directly and draw oil in so easily

[@gt20modding88]

Mine came with transparent dark blue tube.

[@cattmann1405]

Thanks Fearless!...I would never had known what that was or it's purpose. Great vid! Question: Is the volume and/or pressure of "splooge" exiting the pcv going to be sufficient to scale the incline and length of your tubing and make it to the catch can? And that which doesn't reach the can, will it be problematic for it to drain back into the pcv while the tractor sits idle? OOppps...never mind! I read where you already addressed this issue! Again, Great vid!

[@Fearlessfront]

Actually, just tested it yesterday, the oil has NO PROBLEM reaching the can. It works beautifully. Funny how many nay-sayers there are.. I bet most of them have never had any experience with these setups.

[@cattmann1405]

Awesome!...I know I haven't, but that's why the questions were asked. Didn't read all of the comments but would venture to guess more out of curiosity than criticism...either way, that's YT. You throw out innovative and fantastic ideas and solutions...that's why I subscribe! Glad your setup worked.

[@luigiprovencher]

Not nay-sayers, lol I don't think. Just trying to look out for you.

[@duwaynemurdock]

Why not plug intake port on carb and run a dump hose off the pcv?

[@racingisland1]

you could have just connected some of that hard line to the PCV valve and run that so it dumps somewhere where it won't be exposed to water or mud like coming out the side of the hood. That's what i do with my go kart, and i race on a mud and dirt mix surface and i have never has a problem with any thing going up the line. could've saved ya 20 bucks.

[@Palomino488]

Looks really nice! Nice upgrade!

[@MrHengDoItAll]

hey i just installed to my bmw 99 e36 m3. why it white smoke come to much ? when i open the hood i saw oil dripping from meter(clear hose) oil catch can. Can leaking catch can hose make white smoke ?

[@reweydewy]

You should flip the bracket the other way to drop the can down lower. I realize the can can then slide off but that can easily be fixed. The can would be more level with the carb

[@positivenegative6525]

Can you please do a tutorial on how you can get a horizontal shaft engine working on the vertical shaft transaxle? My vertical shaft engine is half blew up up and im looking to get a diesel, which are almost only in horizontal shaft. I need the torque so i can do some extreme pulley upgrades that i cant do with this 10 horse gas engine.

[@steved7487]

hey you did a great job on your hood with that metal grid

[@devinschmitz7813]

I like the catch can and the air filter

[@camSstith]

havent looked through your comments to see if you have updated with any issues with the tubing used in this Catch Can installation?

[@robertbee9776]

Your chanel is the greatest ever, but you spent twenty dollars on that new fn can. I see you can weld too so I wish you would take that shinny can off and get your twenty dollars back, then get a piece of old pipe from off of something else and hammer one side closed and weld shut. Tap a drain plug if needed. then weld two small pipes in the top, hammer as closed as needed first. Also be sure to put gobs of JB quick weld somewhere as that's the American way man. I wish I could help as it looks like so much fun. I would also like to see major sponsors take more of an active interest in supporting activities like your channel as you could use more motors, frames, pro-tools, compressors, explosives and cameras to add to the fun. Just thought explosives would be fun but not necessary.

[@Tmansgokarts]

sweet, I like that idea.

[@skylermcclaflin332]

I would go ahead and take a fitting and the bottom of the catch tank and run it right down back down the dip stick get a plastic hose thing ha and drill a whole in the side of that plastic dipstick and jb weld it or something

[@zivadoberman8918]

not sure i understand where the tube mounts to the manifold is that something special you did?

[@enniofolini8755]

like your design... my mower barely accelerates do you know why??? yours accelerates so awesomely... also could you do a video on sears throttle setup!!! im building a racing lawnmower. :)

[@bobdafred8638]

hey i was wondering if there is any benefit to running your pcv breather back into the carb or not. i noticed on one of your other engines you just had a filter made out of a fuel filter for your pcv breather, but did not run it back into the carb. does where you hook up the breather matter? thanks

[@b-vm]

shouldnt the catch can be below the oil output because gravity?

[@screamingwombat2125]

Do you know what condition the valve seals are in? I had a go kart with an old Briggs from a tiller and the seals were wearing so it had the usual smoke on startup but when I took it around my track it really blew smoke. I put new seals on it and it stopped the smoke. I should have just put a whole new engine on it though because I stuck a bearing on the crank and it wollered out the block lol

[@reedvending2384]

ive just used air line dryers on my car pcv system. worked well.

[@steven7554]

What if you ran the hose that goes to the out port on the can to were you change the oil

[@davidiramills]

what made you thank of doing it like that ? besides the oil that was dumped in to the carb ?

[@destinlong6740]

you should make another lifted mudding mower with a snorkel on it that is a diesel

[@WaveAction777]

I'm wondering if the oil will just fill the lower part of the hose and collect there instead of being sucked into the canister. Time will tell I guess. Stick a nitrous sticker on the can to throw people off.

[@garrettdixon5970]

I need your help I have a soun to be muding mower it has a 8 1/2 horse Briges in it do you think I could run a witch off it or not.

[@nicholassmerk]

Use a venturi in the exhaust system with a car pcv valve.

[@MrMistasparklez]

Im getting a toro wheel horse with a hydrostatic transmission would that type of transmission hold up to a pulley swap and some engine mods

[@dragata1]

I should of done this to my Opposed twin when i started modding it as i got a bit of extra blow by and when she reaches 5k rpm she tends to burp a small amount of oil into the air breather case and if i dont watch it ill start having it run into the intake plan on changing it when i do a special snorkel update in the near future lol

[@Fearlessfront]

it's a really cheap and easy mod to add. Should only take about an hour for the install. I started to have problems when I was cornering hard under acceleration.

[@dragata1]

i started having the issue when i was doign some minor hill climbs.

[@Fearlessfront]

MowBandit yeah, that would do it too

[@MrUltraworld]

I saw this one on ebay. It's less than $20, about $150 less than the others out there. Did it work for you?

[@carshowkid51]

Ok I'm sorry... But I know you have said it probley a 100 times but what is the murray?

[@dc5000123]

Good price on that stuff

[@MrTrucking34]

what size wheeler tries will fit on the back of my mudding tractor

[@theman9764]

You ever thought about doing a V-twin swap? In your opinion, what are the pros and cons of doing a V-twin swap? I'm in the middle of swapping one onto my mud mower and just wondered if it's worth it, thanks

[@MrTheHillfolk]

Yea I just got a 20hp v twin and wanna swap my 12 flatty. I know the 20hp mower we cut the grass with is a very thirsty beast compared to the 12hp. And I bet the transaxles get a lot angrier quickly when you put like 70% more power to it. Who knows, we may like em, or not, and wanna swap back. But I was from the school that more(hp) is always better. I'm just not sure on how long the other parts can take it.

[@Rehabcycles]

This carltch can is for gas or oil? So your returning it back to your intake why?

[@corbinnelson907]

What about the golf cart when are you gonna start the build

[@brandonmalahtaris5714]

Hey fearlessfront i want to make a dual engine racing tractor do i need the same hp engines or can i have two different hp engines

[@zacarnzen4923]

Could oil in the carburetor cause cutting out in high rpm’s?

[@DareBear243]

it was a great job

[@codyjones7195]

hey bo just got mine in the mail

[@codyswilley]

Yes

[@MajorHorstPower]

Howdy fearless! I know this is a few videos back, but what size belt did you end up putting on the murray when you went through your pulley swap?

[@MajorHorstPower]

Ok. I looked through that vid again and saw it is 94 inches!

[@MrImpact66673]

Now it's time to really test that snorkel lol

[@Cardude12344]

Fearlessfront I was wondering of I could put grease in my trans axle instead of oil can u pls message me back or comment

[@WeldstarCreations]

Check out General Transmissions (You Tube and the website) The RS800 is almost as strong as a peerless MST 206 (221 ft-lbs. vs. 225 ft.-lbs.) and is claimed to be a trouble-free transmission with a torque converter setup similar to a snowmobile, scooter, or ATV. Already on Sears and Husqvarna tractors.

[@Fearlessfront]

thats pretty neat, donno how it would like mud and water though. Would be neat to have on a racer though!

[@andrewdoran3573]

what size front pulley do you use on the murray?

[@MaximumMPH]

looks smart on their!!

[@riclin65]

Hello, have you emptied the tank since you installed it? I made an installation identical to yours, and I have nothing in mine ... thank you

[@jonnyhill8965]

for an oil catch can to work properly, its need to be internally baffled with a condensation plate , connections should be placed away from each other, requires air flow over outer housing etc etc.. lot of the L cheapo cans are for cosmetic purpose and have near zero design consideration, like having the lines at the same point makes them very inefficient collecting crank case vapour.

[@Fearlessfront]

this one works just fine. It collects oil no problem. I've already drained it once after my recent "time attack" video. It solved my problem

[@scottashby3030]

ready for romp

[@zivadoberman8918]

any advantages with the carb intake filter?

[@ghostie112004]

have you fixed the head gasket yet? that's the main problem ive found to make them smoke like hell round corners .the compression leaks into crankcase and blows oil out the pcv into the carb. mind you the catch can looks sick

[@Fearlessfront]

no, that usually a problem for OHV's, this is a flathead. if the gasket blows, the motor wouldn't run

[@ghostie112004]

ah yes didn't think about that cheers

[@JodBronson]

Hahahahahahaha. Don't take it to the dirt... We " Niggas " LOVE Bling Bling !!! BTW... I LOVE THE SET UP !!! 2 THUMBS UP !!!

[@eddiesketty1231]

I got the same one just wondering what is the lil adapter for

[@davidabraham3873]

hey fearless my lawn mower engine i had put together after i completely tore apart it after before i attempted to start it i took a different carb from a different briggs and put it onto this briggs but this one had an ati-back fire solenoid and i had cut the top off and put it back on but went to crank it over and it keeps back firing through the carb air filter what could this be from thanks

[@Fearlessfront]

is sounds like either the timing is off, or the intake valve isn't seating all the way during the compression stroke.. When you put it back together, did you pay really close attention to the alignment marks on the crankshaft, and cam shaft when you re-assembled?

[@davidabraham3873]

Fearlessfront yes i did but there is a possibility it is off just by a notch also don't think it is the fly wheel key because i replaced the fly wheel and the key was still good if worse comes to worse rip it apart and put it back together thanks for the info

[@nathaneast4846]

Is that catch can working? Is it not to high

[@therealsmithracing2570]

What size is the front and rear pully?

[@FattyDoveRacing]

In a different video I thought it was a power steering pump

[@johannesaize1205]

this lawnmower seems more like a proffesional offroad tractor

[@dakotaelam4662]

Are you still doing the golf cart?

[@krispykrisp3719]

Where did you get you're front tires?

[@walkertongdee]

Dude, perhaps you should ask yourself why the original hose was going into the carb in the first place, there is a reason.

[@gizzo123us]

good idear!!!

[@Logan_Trogdor]

I don't know much about these but it looks like your catch can is too high and all of the oil will just sit in the bottom portion of the hose.

[@darylandcat]

The state of California would like to know your location.

[@slimjim119]

looks great it should fix that engine

[@jerryrowe6230]

I will do that to mine thanks

[@robinbillstrom4745]

Can you make a video howe to install a oilcoler??☺

[@tool717]

Pretty sweet mod :)

[@rickbroerman9267]

Just replace the PVC valve... Do it right

[@amarjothunjan3137]

Yo r you going to do the go kart thing

[@FUNNYASSHI]

Cool
