Oil Catch Can, PCV, and Blow By - The Roadhouse

[@RTM459]

running a catch can on my 2010 Silverado 76k and love how it has helped. also don't forget to empty it.

[@marrag1]

I miss these guys I would watch their videos all the time it sucks they quit making KZbin videos

[@OsoBlanco17]

Found you guys while looking for help with my clapped out 87 Firebird. A channel consisting of cars, humor and PBR? SIGN ME UP.

[@bagelbytes69420]

You should put a tube on the inside down to the bottom of the can on the IN tube and a shorter one on the OUT tube, and some steel wool media to catch the oil droplets. The issue with these types is that the air goes right in and out and a lot of the oil vapor still gets into the engine.

[@PabstBoys]

That would actually work really good.

[@71dembonesTV]

Lol I like ya'lls style. gotta use that AC manifold for somethin'. Great video! I put one of these on my truck and the results were very nice! My PCV goes in below the throtle plates so it was sucking in lots of unfiltered junk.

[@PabstBoys]

71dembones Hahahaha! You're the first to point that out. LOL!! Same here bud. Old, tired engine, Lottsa junk.

that was funny shit when your buddy got sprayed in the face with beer.... Good Video gave you a thumbs up

[@PabstBoys]

Thanks Pal. Had to use that take. Way too funny!

[@PabstBoys]

When's your next Yukon trip vid?

[@Raptorman5174]

LOL

[@BackCountryWrenching]

[@PabstBoys]

Sweet! Lookin forward to it

[@rileychilcote8953]

Great video, keep making videos and I'll watch them.

[@teamtinnheia9517]

First time I've come across you're videos, definitely subscribing after just watching this episode. Funny but educational shit. Keep it up! 5*

[@PabstBoys]

TeamTinnheia Thanks Bud!!!

[@ericshere03]

Linked in from a forum, watched to the end cuz you guys did a good job, freaking hilarious ... BUUUUT, you guys put the separator on the wrong line, it needs to be between the line that goes from the valve cover rear port to the intake manifold ... the front line is a vent that by design should be breathing from the air filter box to the engine. Also, I would have thrown some stainless wool in there to help...

[@ThePig087]

Tommy has spectacular taste in t-shirts! GWAR!!!!

[@PabstBoys]

Got that when we went to see them in Vancouver. The marks on it are stains from all the fake blood at the show.

[@lukethornton4090]

+Pabst Boys Tbh this is the third video I have started to watch and your all idiots!!!! The pressure or oil isn't caused by slipping past the piston rings!! Its caused by the force of the pistons going back down!!!! which causes pressure in the engine!!! Which is why all engines have two breather ports!!! one main one off the CRANKCASE!!! and one secondary off the ROCKER COVER!!! The secondary one lets next to no oil in the engine!!!!! the main one is the cause of the manifold and ports getting full of oil!!!! The difference between expensive and cheap ones are the cheap ones are fakes that don't do anything other than looks!!! and do you know why its fake!!! no because you bloody made a fake one!!!!! NOT ENOUGH PORTS!!!!! You need two like you fitted and have one for the pipe from the crankcase and one from the rocker cover!!! then you need one in the top to vent BACK into the Inlet manifold!!!! This bypasses the need for the port in the airbox!!!! Older engines in good cars had these fitted as std!!! but as time moved on car manufactures designed there own system!! which fits a mini can bolted onto the block fitted with a filter that should stop all the oil!!! before its feed back to the engine but over time no fucker cleans them so the filters fail!!!! The secondary setup doesn't give next to no oil so they just got a small filter and thought lets save time and feed it into the airbox!!! which again no fucker cleans these out either and they fail after 100,000 miles!!!

[@PabstBoys]

Luke Thornton Hey Jerry Bullshitkorner One of those arm chair mechanics you were talking about....... We got our first one. YAY! Cherry Popped! Apparently we're idiots, and blowby has nothing to do with compression....... LOL

[@TheNotethatimissyou]

You guys made my morning!!!! Great video!

[@dannyboy6345]

Classic, good mixture of humour and info. Just one thing im confused about is that the airbox hose is normally mounted to the rocker cover to supply fresh air to the crank case, how does this do that by connecting it to the catch can. Does the crankcase draw vacuum?

[@PabstBoys]

+Daniel Borg The opposite actually. the throttle body draws a slight vacuum up through the tube to vent off gasses built up in the crankcase. This is why its called a PCV. It Vents off Positive pressure built up in the Crankcase. Mostly due to blowby. Classically it would be vented off into the atmosphere, but Emission Regulations required that these gasses be cycled back through the combustion chamber and burnt off. Cleans up the air, but makes a mess outta your intake.

[@PabstBoys]

+Daniel Borg He is right. this just got more complicated than it needs to be....lol Classically, there was no vacuum line connected to the crankcase. Just a vent. In the setup he's referring to, this is correct, and I would be wrong to say that it doesn't supply fresh air. On our 4.0L because of increased blowby due to worn out piston rings (over 200,000 miles) the vacuum cant keep up with the pressure built up in the crankcase and it blows out the other way, splashing oil through the tube with it. There are other setups as well, like you would see on some BMW's and other Euro cars, where the crankcase is under a constant vacuum. I'v seen cars that wouldn't idle because the owner forgot to put the dipstick back after checking it. So, At the end of the day, you ARE right. I appreciate you commenting. This will def. help us get better at explaining things. Cheers!

[@EnlistedBudgetVideos]

Love the theme song in there!

[@PabstBoys]

They're a country band from Australia. Cool Cats. I sent them a request, and they gave us permission to use the song. Red Hot Poker Dots I put links in the description.

[@HorseDing]

Hey guys! I was wondering what sizes of tubes did you guys use? (inner diameter) Thanks a lot! Keep up the great videos!

[@momoniu2689]

you should do a vid about replacing the oil pan. about to attempt this one next week, sounds easy but then again its a jeep.

[@marrag1]

BROOO BYYYY!! hahahah i just can't stop laughing x'D

[@chiefblueox4952]

Tommie you are a cool shit brah!.....Nothing like a "money" shot with PBR! Oh Yeah.

[@PabstBoys]

LMFBallsOff!!!

[@gilmolina5451]

i would like see how you guys made your fender flares thanks cool video

[@PabstBoys]

Man, We're gonna have to do something about that. We get so many requests.

[@tk429]

How much oil does your setup catch? I thought you used the back hose on the valve cover for a catch can. Maybe that's later Cherokee's.

[@PabstBoys]

Tim Fox it catches quite a lot, but thats because the engine has so much blowby. Yeah, the hose we used is the one that blows most of the oil, but you could set one up on the other one. wouldnt hurt.

[@aaronhuff4484]

I know this is older but what's the copper line on firewall for

[@Gabriel83580]

If some one can answer me this i would appreciate it. I totally understand the use of the catch can so oil won't dirty you're air filter or enter the intake manifold. But WHY catch the oil? Instead of returning it to the motor from the bottom of the can the same way you return the clean air from the top!?

[@PabstBoys]

+gabriel sapien Because it would be a lot more work to do that. It's really that simple. you could set it up like the return line on a turbo, but you'd have to put a new hole in the block or the oil pan. You'd also have to put in a one way check valve to keep the drain tube from sucking anything up while the engine is running. It's just a lot easier to drain the can every oil change.

[@keithmiranda4337]

Oil in there is likely mixed with combustion contaminants. You can also get condensation in there. Best to drain it out and fill the engine with some nice clean oil.

[@bradleycampbell5933]

dudes! i used to drive a air cooled VW. HUGE crankcase pressure problems. come to find out it is either ring blow by OR the normal air in the crankcase moves in and out of the crankcase as the pistons move up and down, and speed up and slow down. as the engine speeds up, the space in the bottom of the cylinders acts as though it is filled with the mass of the pistons. as that "area" is "filled" it pushes the air out, and as the engine slows or stops the air comes back in.when combined with worn rings and bore, it gets messy. as with my VW, most of it is air being pushed in and out of the crankcase. so how is your oil catch can doing? i need one my engine soaks my oil filter and am now running the hot air cone filter.

[@PabstBoys]

Hahaha Gotta love that pre heated air induction. Oil Catch can is doing good. Does the job.

[@bradleycampbell5933]

i am getting one. my vw had an oil bath air cleaner.....Jeep doesnt need one hahahahaha

[@NotAbdulmalik]

i think this is their first can opening experince!!!

[@takayama1638]

Y'all boys ain't right. But hey, I'm putting a catch can on my F150 Ecoboost. It seems all direct injection engines need them!

[@KermitFrogMeepRadio]

broke two ribs the other day, these guys are killing me with the jokes.

[@_l.m.r._]

España buenas no acabo de entender muy bien el funcionamiento de esto. Para empezar, el aceite que sobra del motor contamina el filtro del aire, por lo tanto se construye un tanque para que se almacene. Pero luego sacáis otra manguera para que vuelva al filtro del aire, qué va a impedir que lo vuelva a ensuciar? So podría hacer el primer paso, poner en el tanque de aceite un filtro y que no hubiera una segunda manguera que regresara al filtro del aire?

[@PabstBoys]

the oil is heavier than air, so the oil will fall into the catch can rather than going onto the filter. After that, oil free air will travel back to the air intake. this will limit the mess. Does this make things easier to understand?

[@Veritas_mens]

+Pabst Boys Hey guys, g'day from Australia! A few people I've watched talk about using steel wool (like pot scourers) in the can to help as a filter. What do you guys think about it? Great video, too!

[@PabstBoys]

Mathew Wood From what I hear, they work really well for limiting the oil from sloshing around. Not so much as a filter. been meaning to put one in, just havent got around to it. G'day Australia!!

[@cuttin_hardtv1795]

what if you dont mount it back to your air box what if you just throw a little filter on it?

[@PabstBoys]

Yeah, that's fine too.

[@yeuEhd7393gwueh]

it's so Tomihito. he is a my friend from japan. how about feel at Canada? where are you living a Canada?

[@PabstBoys]

Yeah, Its me Tommy (Tomihito) and My friend Clyde. We are in Squamish BC You need to come here and drink some beer with us! Cheers!!

[@yeuEhd7393gwueh]

OK. all rihgt!!! I know it go to meet to you and your friends. I'll Drinking a Palst beer it's so nice. I wanna go to Canada. I'll go there when You stay keep here. I go to New zealand to next month. My brother live in NZ. I hope Tommy came in NZ 3/22-4/2. It's my mind. Squamish BC is so beautiful and what a good view!!! You so nice life. I'm so happy to. Tommy how long lives at Squamish? You have a good friends nice place and many beer so it is a Fuck'n cool luck. I want to talk to you. Please make a times so have your mind. Sleeping now. more give it away next time. Cheers!!!

[@cowanr775]

For this to be fully effective it really needs some sort of baffle between the inlet and outlet. That will provide better separation between water and vapors. Actually, I wonder if this unit will even work... No offense.

[@PabstBoys]

Robert Cowan I can assure you it does work, and does a pretty god job at that. A baffle would probably be needed if we had used smaller ports on the can. With the ports so large, the vapor travels through the system at such low velocity that liquid droplets cannot become air born and travel upward. Rather, liquid falls to the bottom of the can as a slow drip as it was doing in the airbox before the can was installed. I see your point, and no offence taken. The Catch Can does its job and does it well. One thing was suggested about putting coarse steel wool in the bottom of the can to cut down on the liquid sloshing around. Thats a great idea, and we'll be going with that. Thanks for the input bud.

[@cowanr775]

Pabst Boys That's actually a really good point regarding the size of the fittings. Most of the aftermarket units come with 3/8 fittings which are obviously really small. I've only seen a couple that have 1/2 inch fittings, but the stock PCV system on my Volvo uses a 5/8 inch line, which is probably the largest that I've seen, especially on a 4 cyl. I can see how your larger fittings and corresponding lines would do exactly what you are saying. Well done!!

[@TheMrDmack]

[@nilphuxgiven]

With no media in the catch can, how do you know there are no vapors being drawn through the can and into the intake manifold?

[@PabstBoys]

you want vapors to get through, just not any liquids.

[@nilphuxgiven]

Pabst Boys Roadhouse Get through to where? Out the filter and to atmosphere? Sucked into the intake manifold? Vapors condense and become liquid when cooled.

[@PabstBoys]

They mostly cool and condense in the can because its away from the engine and much cooler. Other noxious vapors carry past the catch can and are re burned after passing back through the intake.
