FACTS.. Absolutely awesome group of guys

[@enermaxstephens1051]

@@MotionRaceworksOfficial It would be really cool if the catch can had a way to see in. Like a line down the side, similar to an oil jug where you can tell how much oil is left in the jug. Even just a sight glass may be enough, if it was placed midway between the top and bottom of your can. You could check every once in awhile with a light or something. Then if you saw oil you'd know you had some kind of problem since the catch cans don't usually fill up.

[@GorhamWorks]

The air/oil film finding a way out, 100% can confirm. I have a baby 700 hp BBC 540 thats NA and had the PCV vented to the intake. Idling, around town driving nothing and not a big deal. But when giving it the go pedal, oil was pushing out the filler cap then running off the back of the engine and making a mess. I'd also get puffs of white smoke too from it being burned in the engine. First build I've done at this power level, learning as I go, and solving problems as they come up. I ordered one of these cans because the baffling and am excited. My first Motion Raceworks product. Love that you sent an email with how to setup and the video was full of great information. I didn't even think about if you're venting to the intake how it could throw more air in, mess with your AFR and need tuning to adjust the top in. Cheers!

[@jasonpatterson947]

I have 0% of needing to know this. But, I enjoy learning and hearing Doug talk. 🤣😂🤣😂

[@franknbeans3651]

When we first started to run Methanol through the big block in our drag car, our crank case ventilation was inadequate. We found out that it can be very dangerous. Driver side valve cover (cast aluminum) exploded sending pieces into the fender and fiberglass hood. Could have been a bad deal had someone been leaning over the fender with the hood up. By the next weekend we had a crank case pump never had a problem after that. This was well before Motion Raceworks came along. But lesson learned is that Doug is right and that crank case ventilation is very important and to make sure you have a good system in place.

[@laa0fa502]

Running a PCV valve?

[@rancherodave]

Probably a vacuum pump system that is driven by the drive belts. Just put one on my 410 ford cleveland stroker.

[@normenderle550]

These tech tips are dynamite for us guys that are getting back into the performance scene, thanks for the clear explanations.

[@TokenTombstone]

Just a couple days ago Cleetus told us to put the catch can vents toward the front of the engine because of the G force during acceleration tends to push oil out the back of the covers. You guys need to get on the same page about this stuff.

[@gregcombs1573]

Vacuum pumps- how they work and how they attach. (I know that's more of a full-on racecar deal, but it would help guys tremendously)

Made one at work about 8 months and did some nice baffling in it. Man the difference in the cleanliness in the intake when I did injector change for my mass air swap. in my 96 351w powered f250 the milky yummyness and my dry filter tells me I did a good job 😁 thank you for another good video.

[@trentongulley6641]

Many people have small oil leaks they cant figure out because they aren't letting their engines properly breathe and have bad crankcase pressure making the oil push out anywhere it can. I have a supercharged Camaro that made 753whp but I had large amounts of oil bubbling and fumes coming out of the little breathers I had for each stock LS3 valve cover. I also had oil coming out of front main seal multiple times. Found out that I needed to allow engine to breathe better by plugging up the little pcv ports on both stock heads and getting bigger breather lines on each valve cover to reduce pressure. My oil leaks were fixed after that and now that I learned that I bought 2 Motion Raceworks breathable oil catch cans with a -12an setup for my new engine.

[@SixOhhGeeTeeOhh]

Just installed your billet catch can and valve covers, high quality parts for sure

keep up the good work !!!

[@jamestone265]

Catch can are good for ALL engines. I’ve had a Ford Performance on my 5.0 F-150 since new in 2018 and a Moroso on my wife’s 2015 Honda Civic since since 2017. There is ALWAYS oil in them when checked. My LSR engine has had a vacuum pump for 25 years and because the engine has close to zero leak down the container has only had water condensate in it.

[@ryanwells2080]

Thee most badass company right here!!!!!

[@Justls1v8parts]

Thanks for video

[@Justls1v8parts]

With valve covers is this from oil can filling points

[@maximusvonce1381]

Exactly how i do it on my 68 mustang fuel injected 438windsor street strip car. Run 2 Moroso baffled open breathers to a catch can with filter on top. I still occasionally see oil sneak out between breather and valve cover seal, but nothing major. Both my moroso breathers have a filter inside of them and they are baffled. Best breather design i have yet to see. My AFR valve covers have a small baffle over opening but nothing like the valve cover baffles in video. I see steam coming from catch can filter so the system works well. Its a borderline race motor on the street.

[@m.pietro9087]

Thank you for the video, it was very informative. My car has 440 engine with a mild cam, it has a PCV valve, in order to use a catch can should I delete the PCV valve? Thank you.

[@CLCIII]

Good One!

[@burneswhitehead3020]

Thank you for the info. Just got my first supercharged ride. Mabe i can save the motor it was not set up right when i purchased it

[@duasobA]

great informative vid, 1 question. would the vented catch can decrease the engine pressure? thanks

[@katemcswan7627]

Love the product but just wondering about volume of the tank, in Australia we have to run a 3 litre can for circuit/track applications. Do you have a bigger one? I’m having trouble with my my new LS putting about 2 litre into my can over the course of a weekend.

[@JohnRoberts71]

Great content thanks for sharing, very informative

[@hunterallen1280]

I’ve got your billet valve covers and two of your single loader catch cans, one venting to each valve cover on my boosted 416” that seem to smoke a little more than my liking, any suggestions or live with it with that kind of cubic inches

[@mrgvnmcld]

Would you recommend running 1 line in (inline 6 turbo) and using an exhaust scavenger set up?

[@brianwilson5666]

Hey you guys should do one on caltracs

[@stranglehold999]

I've heard the L8T and other Gen V engines need the additional vacuum from the intake connection with a more traditional catch can to effectively evacuate the vapors from the engine. Thoughts?

[@HemispheresWines]

I was running a line from the PCV to the catch can and then other from the vacuum back of carb. Sounds like I don't need a PCV and to plug the vacuum on the back of the carb? Thank you!

[@alfenner3309]

Best video on this I have seen- I have an 06 mustang 4.0 v6 that has been supercharged (root style) off of a 04 lightning. In order to mount that sc on the intake, one had to be fabricated to do that. So saying that. The passenger side pcv and drivers side, I think is is called a ccv are both not connected with hoses as they normally would be in stock form. So, I'm looking for a scenario that would best work for this set up I have, please. Other info. - egr has been deleted -no intercooler or heat exchanger -no meth. I'm working on this -car dynoed at 380 rwhp I also have a 2015 chevy Silverado 1500 LT 5.3 flex fuel. I'd like to add a catch can to this as well. I live in cold MTvand I have heard running these can be an issue in colder weather. Is the something additional I can do in the colder months? Your help would be greatly appreciated. Thanks

[@peppermintnightmare4741]

I like this

[@msloquet]

Have a 1964 lincoln old style system hose coming off the oil cap so I get crankcase fumes. Would this work without plugging into valve covers?

[@ScoutYa-cg5sd]

So this same setup applys to 6 cyl aswell yes? Wanting/needing to put a catch can on my is200 was wondering if all was needed to be done was attach a hose to my pcv valve and the other hose to the exhaust side ventilation correct?

[@1982mmag]

is it true that this breather style setup generate a nasty in cabin smell specially under boost?- if yes is there a way around it, such as the exhaust scavenging setup?

[@djrednitro4116]

When I installed the catch can with the filter, there was a stiffing sound and vacuum leak, I had to remove that filter on top of the catch can but I don't understand why it was provided

[@jasgap]

For straight 6, do you block 1 of the ports? Or is there another version of the product?

[@robhatezit5056]

Hey mate im from Australia 🇦🇺 and currently running a worked 6ltr v8 in my Holden commodore and im constantly getting fumes coming in to the cabin and was wondering if this catch can will fix the issue thanks

Do you have a video for a sbc not LS motor and how would you run it ?

[@markhitchins7100]

Would a catch can work with a holley sniper on a stock Holden 308?

[@alundrasrt]

So oil vapour pass through by the filter too?

[@aserrao43]

Does the filter need to be oiled or are they dry filters?

[@tyecampbell6631]

Do you get rid of the pvc valve to run a catch can?

[@faridgadimov5955]

How about pcv valve?the one going to intake behind throttle body

[@antoniobarrientos1230]

First God bless you, where I get a catch can like that, thanks.

[@408dodgeram]

I've been running an header evap system but my new setup doesn't really allow for it. Could I run this instead

[@jasonstrester]

What happens if you forget to empty your can? Will it damage your engine? Or just leak out the vent or blow a seal?

[@tattedsailor2255]

Would yall be willing to help me out with doing a catch can setup on my 2010 Cummins?

[@dougbeckwith768]

I know this is probably overkill, but it's my line of work, and I see things a bit different. For instance it would be nice if you could incorporate a flow rate indication on your catch can for a visual reference. It could be used for an indication of clogged/pinched line or an over pressure issue. I imagine one day, if it is accurate enough, a bench racing conversation comparing the CFM created on a stock motor to a more enhanced version of said motor. Let me know if you need a hand with the instrumentation side of it.....

[@KCadbyRacing]

Since there's a ton of variables it would be easier/better to monitor crankcase pressure and many racers already do that.

I was just trying to kill two birds with a single stone.

[@DirtySideGetsDown]

I'd like to see a tech tip video on running functions on switches. ECU's these days have the ability to control multiple fuel pumps, electric water pumps, intercooler fluid pumps, etc. Why are people still running all of that stuff on manual switches that can be forgotten?

[@jacobschillig7290]

Would you recommend one on a stock 6.0 Silverado that tows a lot? Would baffled valve covers be needed in this situation?

[@M3MPH1SM0J0]

For longevity purposes any engine can benefit from a catch can. It helps prevent oil from being recirculated back into the engine in places that oil doesnt need to be. There are different kinds, such as those that dont actually vent the pressure, but simply collect the oil and send the pressurized air back into the manifold, which maintains your factory emissions system.

[@MichaelNowell724]

Is it normal for the catch can to smoke a lot at idle?

[@kariannestudeman1909]

I was hoping you would say something about PCV valves on OME? cars to explain at an even more basic level, I hear people say "the engine lights on be cause they want you to change the pcv valve, but their just trying to make money" Is this at least kinda on that same though line, or am I wrong? Oh by the way you guys rock!

[@howabouthetruth2157]

I think ya meant "OEM" ( not "OME" )........or am I mistaken? OEM stands for "original equipment manufacturer". When you buy replacement parts for your factory original vehicle, certain parts available at auto parts stores are listed as "OEM" parts, meaning they are satisfactory parts with the same spec's as the original part. ( at least they are suppose to be ) On factory original engines, it is very important to replace a PCV valve once it has become all gunked up after a long period of use. Because once a PCV valve becomes dirty & clogged up ( even partially clogged ), your valves, intake, and combustion chambers will start getting all sludged up, resulting in poor performance & economy, and shorten engine life.

[@adeptpeasant6161]

Would it be possible to create a vacuum in a crankcase to minimize this problem in the first place by a vacuum pump of some sort?

[@PredaFran]

you can get a vacuum pump, they are used with dry sump systems and just used to help with piston ring sealing, a properly functioning PVC system should work just fine tho

[@adeptpeasant6161]

@@PredaFran I would think that would be ideal under boost conditions but I like the KISS principle. Keep It Simple Sir

I can't find an answer but if your car only needs one port of the catch can, can you cap off the other port? I am working on a sxs that the catch cans are all single port use with a drain on the bottom and a filter on top there is no second port. There are some nice catch cans that I like but they only make them in dual port, I was wondering if I capped one end of the dual port if that would be ok? I don't know how the dual baffles would work. I think it wouldn't matter but I wanted to ask

[@MotionRaceworksOfficial]

We also make a single port can

[@andrewbarreto3202]

As far as installation goes, does it matter which line goes where? I'm curious don't wanna fuck this up.

[@MotionRaceworksOfficial]

No sir can go to either side from either valve cover

[@nathangresell1534]

Pcv is more caused by natural blowby, not necessarily so much as by the movement of the piston.

[@MotionRaceworksOfficial]

It’s actually both

[@nathangresell1534]

@@MotionRaceworksOfficial but wouldn’t the movement of the piston cause the turbulence and air pressure changes around the rotating assembly primarily while blowby is left to cause the increase of gasses entering and therefore having to vent out of said crankcase?

[@markdavis8888]

Using the generic term "air" for any gases in a conversation is wrong and annoying. "Blow-by gases" would be correct for this discussion. Air: the invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen. Obviously there is also some CO2 in there.

[@ldnwholesale8552]

For a road car a PCV is good though not essential. Though a legality to have one,, for 50 years!! For a race car a NO NO. But fancy catch cans will not improve the car any. A couple of 3/4" hoses pushed into an empty 5 litre oil bottle will catch the oil fine. ten 1/8 holes drilled will bleed the pressure. AND they should be close to the engine,, not in the back which is plain dumb. $5 worth of hose and recycle some waste. Unless you like shiny expensive bling shit!! For road racing a catch can must be mininum of 3 litres. And all these full fumy turbo drag engines must push out quite a deal, Ideally breathe the pan into a rocker cover, crankcase fumes then go from rocker covers to catch can. I have done that for over 40 years and unless the engine was junk never ended up with more than a few ml of oil in the can, usually more water vapor. This on road race and speedway engines.
