- Most often overlooked aspect on any performance related engine the Proper Crankcase Evacuation and in order to lean towards that or achieve it?
Understanding its cause and reasons will definitely help as we see most just copy or follow what they see in FB like just put a breather on the valve cover not realizing on continuous runs that oil drain is hindering its ability to breath out crankcase pressures from the bottom or block
Here are links that relate to this and especially volumetric efficiency

Proper crankcase ventilation indeed helps achieve better efficiency as discussed in this video below

I've spent over a year trying to understand this lol and you finally cleared it up for me, sir. But I'm in a d series
Nice
Content is amazing and well done. Love the way you make it easily understandable for the average Joe. Excellent information. Thank you
Oh wow thanks man! Actually I’m an average Joe so it’s how I’d have understood it easily too 😎
Man great video great content thank u for all this knowledge thanks
Oh for sure man! I can imagine how it is when I learned about it? I felt I knew the secrets to the fountain of youth lol!!!
can't help but binge watch
Actually half of the things I realize? Are always thoughts in my head, I mean stuff I learn and it’s just there and I figured this is an excellent platform to share the insomnia 🤣😂
@@SRDmotorsports i have no choice i work nights…hey maybe I can visit your spot man im from LA too!!!
@@WorkingClassMedia ah night owl I see!
good thing I invested on a DIY block breather with a 90° an fitting pointing up...
Oh nice on the “pointing up”
And indeed on a b20 it is quite more beneficial than most as the block doesn’t have a breather unlike their “vtec” counterparts
Awesome work like always brother 👈🔧🙏❤
Thanks my man! I know this be something EZ for you on the CivRV ftw
Definitely got something planned 🔧👈🙏❤
U got IG
@@shiftlifegarage3284 sweeet man!!
@@shiftlifegarage3284 yeah I do, lemme check my username and get back to u asap as I don’t usually remember it lol
Are those golden eagle cam gears the machined ones or the titanium? I really like the mirror finish! I wanna say they look like the machine finish but it’s hard to tell lol. Thanks for any feedback!
GE silver I think was surprised too it looked clean and clear like as if mirror finish
Where would you install an electric vacuum pump on a k20? I'm thinking the pcv valve. Good vid.
Yeah that could work
I always wondered why many builders here in the philippines put the breather on the valve cover. When making the breather on the crankcase makes more sense.
Yes!!! Thank you I’m not alone 😂
Actually was dying to say on the video that “doing that cuz u saw it” is a monkey see monkey do move but
In the Philippines… u get hate by doing nothing so imagine if u say stuff lol
Sidenote* maybe “they” don’t know or worst “they don’t understand” engines lol
On my naturally aspirated sohc, if i only vent from the back of the block only, the catch can fills up super fast.
You can use a exhaust crank case scavenging system like on v8 hot rods as the more air you flow through the exhaust the harder it vacs down the crank case. Although you will need some air oil separator set up.
Yes sir! That’s also in the pipeline (no pun intended)
Back in the day I had a pair of those (Moroso) think that actually had a check valve and all
Interestingly enough this isn’t so common on the import scene but even VW class11 friends of mine do it and swears by it since it’s a strict class so we know it does help
@@SRDmotorsports i run a set up like this on my 1.9TID as removing any oil from the inlet tract greatly reduces the chance of run away
@@SRDmotorsports czcams.com/video/tkRy23t2N7A/video.html i followed this guys advice and it helped a good amount on my older 1978 spitfire build
@@501isa now that makes sense and yes crank e-vac is “Next” ftw
Hi sir. Great video! I have a B20 vtec aswell. Just want to ask, is it possible just to install one breather plug and on the one nearer to the transmission? Or should be on that hole you installed a breather on your video at 4:20? Thanks! :)
Any location is fine but running 2 breathers is still not “overkill” or “not too much” so that’s something to think about
@@SRDmotorsports got it. Thanks so much for the reply. Will follow :).
Alright man :)
Makes sense to me.
Yes sir! Thanks man!
Nice vid! Very informative. Maybe in the future you can teach us how to swap a b series (preferably a budget b20b) in to a eg or ek chassis the filipino way. Ever since i moved here in the philippines i got hooked in the honda scene and been wanting to build a b series eg ever since but all i can find in the forums about b swap in eg or ek chassis is that you need integra parts which is kind of rare here, i've been thinking can local crv axles be used as alternative? and what passenger side engine bracket to use because from what i've read, the b20b passenger side bracket is to "tall"
Oh that’s true on brackets
Def something cool to look into, what chassis do u have? EG right? I’m gonna look into this and see what goods we can put out
@@SRDmotorsports Thank man!
@@michaelscott6669 no worries man!
Great video bro. I like the idea of including the Integra as one of the most famous Hondas. I would like to ask you... I see that you sometimes use the red and sometimes the blue color on the engine block. I am quite sure that it means something. :) Thanks for the answer and keep up. Great video man.
Oh it’s just random choices hehehe but thanks for noticing hehe
@@SRDmotorsports I thought it has a meaning with the intake or upper or lower part connecting the gasket. :) Thanks for the explanation. Hit that like button on my upcoming car video. I think that you missed it. :)
@@RRRRefuelRideRace oh no meaning just random
@@SRDmotorsports OK, you know... details count. :)
@@RRRRefuelRideRace yuup
Would u suggest routing a pvc valve on Valve cover to intake manifold on a k24 ?
The k24 like the b20 didn’t have one in the block right? Makes u think about it
But even the B series or D didn’t have a pcv valve on the valve cover
Time to walk outside and see what my builder done also on motor my car is running low nines in the eighth on a full built all motor ls v tec haven’t been bk though after I fixed the exhaust and the loose alternator belt. Also do you think the closed deck is y my coolant system puts a lot of pressure in the coolant lines.
Oh snap low 9s is a good good time!
I think there is a chance on that on it being a closed deck
@@SRDmotorsports low nines in the 1/8 mile isn’t to bad for a all motor car. But I feel with a closed deck it’s less area for the same amount of coolant to flow through so it would make a lot of pressure. My head hasn’t even had work done yet. I’m racing this weekend at midnight madness in Southwebster Ohio so my yonaka muffler is old and stopped up so I’m going to use a straight through old school A1c I think is the name of it
@@tjabdon606 yes low 9s is more than decent and real good actually…
And I can see what you’re saying on the deck surface area thing it makes sense actually
How do you deal with the catch can constantly filling up with oil? Atleast that has been my experience when running lines off the block on these B series engines.
We only see it on hard runs but it’s why the same kind of catchcan like T1 the 2 lower ones are for the block this way it drains it out when on idle…
Another trick that may be helpful is the fitting to the block? We use a 90deg elbow/turn that goes upwards vertical and we try to keep it going up near the bottom of the manifold this could probably lessen the oil fill… hopefully you visualize it
What can we do on the K24 to make it breath better? I currently have a small filter on the valve cover breather but what can we do for the block? Top video and information btw 👌
will have to check further on that for now
Sounds good 👍 looking forward to hearing back what we can do with the K Series.
yep! Will look into it for sure
I have made breathers on the valve cover and in the block... car is making about 10 whp than average NA B16
Now that is awesome! And that 10whp when you think about it, is more expensive if it was thru other parts mod or addition…
Awesome to know this! And you got it man!
@@SRDmotorsports thanks man! I'm currently building a turbo sleeved B16 aiming +500 whp. Now these breathers are even more necessary!
@@HugoMatsubara oh snap! Man!!! Tires will hate u looool
Hey great video is there a port fitting available for h22 crankcase ventilation? Thanks
None , gotta weld a fitting behind
@@SRDmotorsports thanks 12 AN is good?
Yeah AN12 is big enough I think what u can do is weld an AN12 nut behind the block right by the balance shaft curve? Cuz if the balance shaft is eliminated then that’s an empty “area” inside the block kinda okay spot
@@SRDmotorsports thanks I will do this should I go with mahle gold pistons or should I sleeves and go wiseco 🤔
Well cost effectiveness hard to beat Mahle Gold so I think that’s alright
Thanks for the info would like to see this info on h series
Oh sorry I didn’t get to mention same for H series but we weld an aluminum AN fitting this way u bolt it up to the block
Il check my photos on file and gather up some of it and info and “next” vid regardless of the topic il put it in there as commercial for you guys
@@SRDmotorsports thanks bro
@@jdmejhatch9391 no worries man totally forgot about it and weird cuz I have an h22 at the shop sleeping for when I get to build it
@@SRDmotorsports Ill definitely be ready to watch that 💪🏻
My biggest concern is finding a spot to put the catch can in a Honda engine bay without battery relocation 😩
Oh that is tough indeed… the factory airbox location? Only downside is it’s lower than the vc so must loop the vc hose if ever u are venting both block and vc
@@SRDmotorsports doing the crankcase ventilation only should compensate for vc pressure, it's ok to have a little lubrication in the intake manifold with open throttle not at idle
@@Built_it_by-alex that’s true I mean the factory one it gives more efficiency down there and all which is good but not as enough as we ideally would prefer
I always wonder why those bolts were there
Yeah man
Basically two ways have two fittings on the block or two fittings on the valve cover hmnnn the block seems easier since I’m not a wielding guy for the valve cover
Yeah for the b20 and b18 nonvtec u got two plugged vents at the back
For vtec blocks it’s 1 plugged vent and the factory. Canister on the right so both can be for breather too
@@SRDmotorsports trying to do a B18A1 LS Vtec Turbo with a GSR head trying to see which choice of fittings for the catch can will be perfect
Then same like a b20 u can put two fittings at the back of the block and it’ll be great
@@SRDmotorsports I would consider doing one on the Vtec valve cover but I’ll have to find someone who can wield so that’s a no no for me so I’ll do it on the back of the block like my old B20vtec
Yup sounds good
On the B16A block, can you leave the OEM crankcase vent and just vent it through the other hole by the oil pressure sensor?
That’s what I do for b16/vtec the oem remains oem
@@SRDmotorsports I'll give that a go
Ayt that’s cool
The b16b 2liter build series I did this since it’s a vtec block and had the oem black box
@@SRDmotorsportswhy did u leave the black box on? What would happen if you didn't?
is this applicable on ph16a sir?
Yes
Can you explain more on @4:38
Il re watch it again later
Like the dseries the oem black box is for PCV the system router to the intake manifold with the PCV valve
It does not “breath” out for full throttle or anything over 70-80% throttle
But for idle and part throttle where 95% use their car? It works and it’s good
"there is power to be made with attention to oil supply and drainback" 🍻
"Regardless of piston ring condition, all Honda VTEC engines all suffer from excessive crankcase pressure at high power and RPM levels. This is caused by extreme piston speed, long camshaft timing events, and a PCV system that is completely inadequate at high throttle angles and low manifold vacuum levels.
Many of today's large displacement B series engines are based on new blocks where Honda deleted the breathing "can" (on the rear of the block), causing these engines really suffer from extreme crankcase pressure (frequently high enough to rush past the seals, blowing the spark plug wires off the plugs.) Pressures like these cause oil and other contaminates to severely degrade the quality of the mixture in the cylinders, reducing power and greatly increasing the possibility of detonation."
On your first comment YES!!!!!
Details like “why” jaspers crank was as such 😎
And thanks to Don Flores (RIP) he showed me details of the Mugen d16a6 he refreshed and showed me cool stuff including stock factory rods that are “Mugenized” 😂
But I promise If I get to do a series build of my d16a6 il share some tidbits and talk about it hihihi as I did the Mugen way too lol
On your second comment.. YES! Again
and a lot of small things that could and would help do a better job
Larry Widmer talked about the details he does on the girdle as to function against a “slinging” oil
And from others I read and saw… other tricks that aid in drain back that actually does help crankcase pressure
@@SRDmotorsports Nice!! Are those the polished rods?
@@SRDmotorsports First quote/comment is from Belben, the second one is from Larry 👍
Is this applicable in b18b block with b16a head?
And nung nag install ako normal lang ba na may lumalabas na oil sa oil catch can?
Just like b20 it’s more applicable yes as they don’t have a factory breather so must install them
Oil from the block? Or valve cover?
depending on blowby yes pwede madami or konti
@@SRDmotorsports it is normal kung medyo madami? The oil cames out if i rev it
@@SRDmotorsports thank you for answering me
Keep in mind 90% of crank case pressure is created from ring blow by therefore vent at the back of the block whenever possible
thank youuuuu for saying that! as like on the b20 block, i always always vent at the back of the block
and its nice to see an individual suggest and share the same sentiments 👊
@@SRDmotorsportsif I can only vent through the dip stick tube is it still valid I have good amount of blow by because my forged pistons have a pretty wide gap is what I was told by the previous owner
Any venting helps… just worry if u start spewing oil from the dipstick so check on that always
@@SRDmotorsports will do thanks for the reply
No worries 😉
Unleash more power and you may have a bowel evacuation when you hit the gas. With great power comes great responsibility.
Great line 😎
Hey man keep up the good videos really good information can I contact you on Facebook to talk about about engine stuff I have some questions
Oh hey thanks man!!! And to be honest when I think about it? I always run out of ideas to make a video until just sitting there having a smoke and something comes up and I grab my phone and record asap lol!!
Yes sir, pm me at the shop page it’s on notif so il answer up stuff and thank you for commenting here first cuz sometimes it’s helpful when engine questions are here = means just more activity and comments haha
But yes thru dm’s make it work too so hit me up
@@SRDmotorsports OK thanks man I'll be hitting u up soon today after work I wanna boost my h22a I have some questions on that , I was ganna go all motor but I want more power then that cars are to fast here in Cali need to keep up lol
