In this video, I show you how to install a PCV delete on your car. This will make it so the air and fuel that goes into your cylinders does not get mixed with engine oil. Doing this mod might not be legal where you live so be sure to check your local laws before doing this modification. Another similar mod that you can do that will be legal is a oil catch can. I will have a future video regarding that in the future.
As it stands though, the PCV delete came with the eBay Cold Air Intake and it came to $23 for the set. If you want to see how we installed the Cold Air Intake, click the link below.

Great video on how to do a crank breather delete. I got a GOOD laugh out of this.
That was the breather hose not the pcv valve hose. Your pcv valve hose is going to connect to the intake just past your throttle body butterfly . Not in front of it.
This is correct!
I just saw Scotty Kilmer mention amateur mechanics offering questionable advice on youtube
"Install a delete" yeah I'm not sure that's exactly how that works.
@Bryce Lawrence thanks, I was able to hack your account just now!
Does that work on a 1967 buick skylark engine 340
@@rubenortiz9149 works on everything some cars especially on Volkswagen you might want to add a catch can
@@rubenortiz9149 depending on where you live you might not pass an inspection/ emissions
You’re installing the part that creates the delete. Completely possible. Just as you would install a piece of straight pipe to complete a resonator or muffler delete.
Glad you did that. Hard to believe engineers couldn't move the PCV valve hose anywhere BEFORE the maf sensor. Pcv air is basically UNMETERED air that is essentially a VACUUM LEAK.
PCVs that I am familiar with have a ball and spring so that as vacuum changes (engine rpm driven) the ball moves to keep flow consistent. The "air" leakage is accounted for by the computer. A leak in the pcv hose, like I had years ago, will let more air in which the computer will interpret as a lean condition and so will up the fuel mix to get the exhaust content back level. My '99 Tahoe was idling at 900 rpm and while coasting through a parking lot with my foot off the gas, the truck was rolling along at 15 mph, much too fast when your are in areas where people are entering and exiting a store. I have a homemade catch can system which catches oil and water so that essentially dry air is re entering the intake stream. Where I live has dyno emissions testing and if they see that set up will disqualify you long before the actual test happens.
Would probably get oil on the MAF. Then the MAF wouldn't read right.
I prefer a catch can, vacuum on the crankcase improves the sealing of the rings. but I also agree with removing the pcv valve, routing it before the throttle body meant it's receiving a vacuum at all times, but that's more geared towards boosted cars.
Caleb Quinn the vacuum is much lower and is variable based on throttle position in that re-routed setup. Some way to remove water vapour and atomized oil etc from the airstream is key for the engine’s longevity- I use a bmw cyclone separator and larger diameter hoses
What about the other pcv with the valve, will you add a catch can to eliminate the oil which gets recirculated with the bypass combustion gas?
Dude so well explained I need help with my 1.8 t
Thanks a bunch. Im busy doing this on my Mitsubishi pickup. This explaination eases my mind.
People seem to forget that a PCV system uses intake vacuum to pull excess crank case pressure out of the engine, without that you get excessive blowby, gaskets will blow out shortly, oil will find a way past gaskets. There is a reason why after the 1950s they started useing a PVC. Also a little oil up top does help keep the top end lubbed but a good motor won't be pushing much oil that way anyway. I have seen way to many people remove there PVC and end up with a ton of oil leaks, blown gaskets and oil all over under the engine bay, it's not just an emissions thing. It's something that your motor needs, if you look at drag cars they have catch cans and alot have a pressure evac that use the exhaust to pull the pressure out
Pcv*
This is literally not true or correct in any way
Nah it's just puffing off in atmosphere from pvc port
@@CatFinder3000 it's 100% correct, though moreso on older engines with lower tolerances/bigger piston ring gap than modern motors. I got a steal on the last old truck I bought that was perfect, but it was smoking and burning a quart of oil a week. Noticed the PCV setup was incorrect. Put a new PCV valve in for $5 and plumbed everything up correctly and now it doesn't blow a puff of blue smoke anymore.
Tan simple como pensar que si eso está es porque los ingenieros lo diseñaron asi. No nos van a regalar piezas, se los aseguro
Really should have just added a oil catch cause that mod you did Rob's efficiency
I do
By removing the PCV pipe that connects to intake, the foul air is not able to effectively flow out of the crankcase ( lost suctions from intake) which leads to oil sludge issue. I would recommend to use synthetic oil and change it more frequently if you want to delete it.
I disagree. T6 shell Rotella. Cleans your motor spotless! Trash this fake fraud engine oils designed to wreck your motors
I mean who is not using synthetic on a German car........
You don't need vacuum to pull the gas out, the pressure generated by the blow-by itself pushes all the gas out.
OMFG! and u got 2.5 k likes. There is no hope for next generations.
In a highly boosted turbo motor, like say a VW Golf R or GTI. A stage 2 tune pushes 28-29psi or a Velostor N 27psi ish. The PVC system is overwhelmed and venting the valve cover with a small air filter on the oil filler cap can save your rear main seal or cam seals from blowing out. Turbo drain lines have been known to push oil back up and leak through the turbo shaft seals in rare cases.
Venting the valve cover won't cause a vacuum leak? Trying to build my 1.8t
I'm confused on what this does? Is there any HP gain? would an oil catch can be better though?
Hey man so on the 2006 the PCV valve is inside the valve cover, I imagine it's pretty much just the same plug off the hose that's going to the valve cover, and throw a filter over the return. Thanks for your video and helped a lot
Hi Milan, can this delete eleminate the oil burning?
Loving the vids man👍🏾
Get rid of it and get a catch can and vent it back to intake even a motor with great compression will have some blow by and can get a little messy
had this setup on every car i've owned and have had exactly zero problems, i'm not saying you're wrong but maybe that's just the case with older/unhealthy engines with a lot of blow-by
only idiots puts exhaust to te intake, why you need all that hot air going into intake?
Hello. Is the filter you put on working? Has the engine been damaged? Do you live in a warm or temperate climate? Before installing the filter, the engine was throwing oil out of this breather pipe?
As some others have said, that was NOT the PVC, but the exit breather hose that runs into the intake, post MAF. A PCV "valve" is what that name inplies..a device, go to autozone and look at the wall of PCVs. It's locking into the intake, usually behind the runners, and has a rubber o ring that seals the connnection and or tabs that lock it into place, with an o ring under that. You need to keep the PVC as it has a spring and plunger that reacts to pressure. The best fix for this is catch can where that hose you disconnected can be fed, as well s the true PVC hose. This way the system maintains the vacuum pressure it needs to evacuate the blowby pressures.
Of course John, as you're doubtless aware, it's possible to use an electrical (or mechanical vacuum pump) to create fresh air flow through a crankcase - we don't necessarily HAVE to route the crankcase fumes into the inlet manifold. But that sort of knowledge is way above this guy's pay grade.
jesus christ its about time, i've waited so long for someone to put one of these videos up. Thanks a bunch!
Shame he's got no idea how a PCV system actually works. Or, what benefit he achieved by replacing filtered air from the air box with a separate breather.
Ehr isn't it supposed to be attachted to the intake tube so that the negative pressure in there will make the pvc tube act as a vacuum so it will suck out the gasses?
Its to relieve blow by, and since its metered air, it gets injected into the intake air post MAF
will car run too lean if i vent it to atmospere?
pcv valve is designed to provide a vacuum in the crankcase at idle only to draw blow by gases into the intake to be burned rather than released to atmosphere, it can cause issues with ecu calculations if it is faulty because the ecu expects a small air bleed through the pcv system at idle. if the valve fails the ecu may not be able to correctly calculate map/ maf values causing rough idle, hunting or worse, high crankcase pressure in the case of a clogged or collapsed valve which can blow out seals. blown seals mean an oil leak and possible seized engine if it goes unnoticed.
You said it... Last week i had the same problem with my 2009 corolla vaccum missing... I did all things like Tb cleaning spark plugs changed... But idle was not normal.. Again ane again mechanic team try to clear it. At last they find out pcv was blocked... Then change my cars pcv now it's ok more better to ride no other issues 👍✌️.... So pcv is the most important part of the vehicles..... (From Uae)
an great way to throw an CEL. and the best way not to pass the state emission test. way the go boy!!!
You guys have emission tests? Ewww.
Where blew by gas go if it is a filter and no way to be recirculated or colected?
Don’t you end up with oil coming out the small breather, basically ends up soaked?
i have a question should i do this pcv delete even if my Mustang has low mileage? i was thinking of doing it but other people were telling me no dont do it.
Where did you buy the adapter for that installation? Pvc?
can you add this to a nissan 87 d21 as well as a cold air intake? thanks!
What I understand is pcv valve is the plastic piece on top of the rear of engine. Also I heard of egr delete but not sure of intake breather hose delete. Very sure it is require to vacumm and recirculate air.
Rock&Roll air goes into the breather then out the PCV into the manifold. Air only ever goes out the breather at basically wide open throttle. Hr didn't disconnect the PCV. He DID create an unmetered air leak that is now fucking up his AFR
This might sound crazy but I try this mod 3 years later. Now what he is installing is an air breather filters, not oil catcher which actually goes into the pcv that will be for another mod. What I get is a check engine because the car read it as a leak evap sort of like when u broke a hose and it leak that sort of leak.
What in the heck did I just watch? Hey can you make videos of modding your Hot Wheels toy cars too?? It would be so funny :D
pls give us the update of your pcv delete? its 2019.
I would have hooked up an oil catch can for this, but do you. EGR Valve delete next? ;)
This would be a good way to get blowby and condensation to contaminate and sludge up the sump oil, instead of getting it sucked out by the intake vacuum, and ending up out the exhaust pipe, where it belongs.
2 questions. You removed just the hose or the valve as well?, now is nothing sucking the gases from the crank case, how evacuate all those gases?
i have the same engine and i started getting misfires on the cylinder closest to the air intake. i opened up the plastic intake pipe and sure enough there was a bunch of oil that has been coming through that breather hose and fouling the nearest cylinder. i also removed breather tube and ran a tube down to the ground so oil blow by hits the road and not my spark plugs. no more misfires no check engine light, car runs great. also capped the opening on the intake like he did
Just change the $15 valve
@@louarmstrong6128 I had this too! Where is the valve? I thought it was built into the intake tube?
@@auxmike718 Google your make model and year and pcv valve....takes a few minutes and generally costs $15 or so.
Very good video, but I still get a smell of that vented air in my cabin which is considered as "toxic", so what is your altenative solution for that?(not putting pcv it back bro).
@Benjamin Burlos very clever
What are the benefits? And what if the hose is 3 way instead of 2way? Would i have to delete all 3 ports?
where's a good place to buy the delete kit? and does it come with parts for both ends? I live in Canada.
Why don't you use an oil catch can?
Hi! what about if a car has a turbo, dosn't the oil escaping from thru the PCV help for better lubrication of said turbo? sry for any bad english. not my native tongue! all the best for tou and your brother! Cristian from Romania.
that is a speed density engine right? I wonder if say you were to do that on a mass airflow engine if it would affect your mixture too bad.?? hmmmmm...I never did like the idea of rerunning all that crud back through the intake to get all over the back of the valves and build up and restrict airflow. but I do like the idea of ventilating the crankcase though,
Can I install that in my 06 ford ranger and what that can help with?
can you do this on a bmw 535(n55) or acura rdx 2019?
On 2020 santa fe 2.4 non turbo engine I removed the pcv valve from the valve cover and was surprised as to how little pressure blew out its opening while it was running . Now if I removed the oil cap plenty of pressure escaped( of course right) so I honestly don't think it would hurt to vent it through a filter ..but indeed leave pcv valve connected to vacume pipe with a small air filter on its opening.thzt way intake pressure will remain normal and not mess with fuel mapping
have you done it on your accord...I have a acura tsx 2006 with the k24 does it do the same thing and is it the same to put it on?
That is NOT your pcv valve ... that was your valve cover breather ...
@Tracker Wolff i didnt ask how they worked.
@Tracker Wolff NO i do understand them. He was on the VALVE COVER BREATHER which is DIFFERENT from the PCV. There is a difference between the 2 and both work in conjunction with each other to help expel crank case pressure built by blow by and crankcase rotation. They do NOT do the same thing.
@Tracker Wolff I KNOW WHAT THE PCV SYSTEM IS AND HOW IT WORKS ... My original post was that he was on the valve cover breather and NOT the pcv .... I never asked YOU how it works, i never asked you for a lesson. I was correcting his MISTAKE.
@Tracker Wolff That is NOT his PCV ... That hose he is working on is before the throttle body which is the valve cover breather.
can you help me on my question above?
I suggest no body watch his other videos he clearly has no idea what he is doing
Very dangerous for health !! You will start smelling the toxic gasses coming out of the small filter you added and this will cause breathing problems in adition to skin allergy! you should add a long pipe and let these gasses make their way underneath the car much more away from you and from the area where car cabinet sucks fresh AC cool and warm air !!!!
@@omoyomoyo6986 I think that here in UK is actually ilegal. or not?
what happened to your secondary vent pump vacuum?
My PCV Valve threads into the bottom of the block, does that mean that I have to worry about any effects from water?
what difference between breather hose and pcv hose as function the same ?
Pcv only picks up inert crankcase exhaust. It takes out this waste so it doesnt get into your oil and degrade it. The pcv safely sends the inert waste passes through the entire engine from intake to exhaust and keeps your engine clean
You only removed a pipe and no valve? I have a faulty pcv valve and am thinking of fixing a delete simply because is SO hard to find a new valve, but if I remove faulty valve then how do I attach the pipe to the rocker cover?
Is that a hose or an actual "valve"? If you only take out the hose, how can the valve vent any positive crankcase fume through the "delete" since there is no longer a vacuum supplied by the intake manifold...
I did that to my car and the car lost power it doesn't run like it used to. I think they call that the idle. What do you suggest in this case?
Up that is an air filter, air enters the system to equalize the vacuum. and the blow by is going into the air. I wish there were a golf clap button on on here SMRT
So were does ghe oil vent to ? Just through the filter and drip everywere?
What steps did you take to remove your air pump? What needs to be deleted? I tried to find a vid ... no luck tho
So you dont fully delete the pcv but mount the breather ahead of the pcv? Or eliminate it fully
Good video, but others have said that not having the PCV will cause the engine to create sludge. Those pre PCV era cars engines didn't last very long. I'm gonna go with an oil catch can attached to the PCV side, and vent to atmosphere the other side.
Bought a Fiat Punto where someone had already made this modification. Problem is that the air intake for the cabin was drawing in that stale oily air and made the inside of the car stink. So we removed the catch can as after several attempts of trying to extend the outlet to somewhere it wouldn't smell, we found it was impossible.
What size did you use for the vent on the crankcase and what size plug for the PCV valve? My PCV valve diagphram is torn on my Jetta 2.0 and this is alot cheaper than replacing it. The PCV valve is plastic welded to the intake tube so its easily a $200 part, even more if you get it from the stealership. How bad is the smell from it?
Ken pcv valve is a cheap part you can. Purchase at your auto parts stores for $3-5 and is an easy install.
Do your car need PCV? If you just use straight line between those without valve, will kt work? Whats the point of that valve?
Don't need it on multiport injected cars or dual MPI/DI cars which are most new cars but you can use a air oil separator/catch can instead of doing this.
How is this any different from the valve cover vents on classic cars?
good explanation, how to do the 2011outback?
Right, does a turbo basically do this itself?
So does it reduce carbon deposits like a catch can or does it make more carbon deposits?
It makes a gooey mess underneath the "delete"
that worx fine on my non-turbo car but my turbo car pushes oil out that filter everytime it boost from high pressure so had to hook up oil catch can.
If you did a.pcv delete on a v6 would you need two filters and two plugs?
It is a return hose and I guess you can do that legally if you can afford the expensive KB air filter.. I think it makes no difference because the direction of return air is toward the engine away from the throttle body air flow . The only bad side is when the engine stops and some blowby gases may float out n through the KB air filter not much. The main PCV hose need the engine to have other opening where the return hose you are showing to bring filtered throttle body air flow in to replace the blowby gases that is sucked by PCV . I think you can use restrictor plug instead of KB filter to restrict the amount of air flow going through the return hose into the crankcase. Some models has them . I experimented with a homemade one , a rubber boot tucked tightly inside the return hose to leave only 1/8 or 3/16 opening instead of unnecessary 1/2 or 3/4 opening that you have here.. Your return hose is wide open and it is not necessary. Be careful to not allow anything restrictor to be sucked inot the engine or the airflow. Be sure to clamp whatever restrictor you use inside the return hose end with a clamp. so it doesnt go anywhere.. 1/8 may be too restrictive but 3/16 or 1/4 is plenty as far as the PCV sucking power goes.. PCV sucking flow is pretty low but its suction is strong comparable to hi voltage / low current for electronics in a sense.. I like restrictors because it encourage the PCV to suck blowby gases more instead of the return air coming from the main throttle system through return hose.. I think restrictor help PCV cleanse the piston rings more effectively so that the blowby gases passing hrough them.cannot stick on cylinder walls.and it probably will keep the cylinder walls clean! The engine seems to purr more to my liking than without a restrictor. I dont know why.. I will leave it to the automotive engineers to sort it out and see whether restrictors should be used in all cars to specs be it 3/16, 7/32 or 1/4 depending on the engine displacement , I reckon.. (rubbing chin) 3/8, 1/2 or 5/8 is not necessary
What about the oil that gets sucked in? Does it drip back down into the crankcase?
Will this work on a ford ba falcon?? I got way to much oil coming out into my air intake pipe more then normal
Hey man where did u get the connection for breather
Can this be done to your Mini Cooper? Please explain if yes or no
what about the oil that would fill the small filter... like u said thrz oil that comes back up too... will the filter not clog up from gasses and oil?
im wonderin the same thing
where did you buy the filter and plug? I looked online sometime last week and saw different sized ones.
It came with the cold air intake on eBay. We picked both the intake and the PCV delete for 23 dollars
+milanmastracci 23?! Oh my fuck! $23 for a sexy engine bay.
Best channel ever,,, can do a video of how waxing ur car without any machines I mean at home
he has one just do everything he did without the machine
+Yemi_Rs TYVM! Ma man I appreciate that 👍
I have delete my pcv already, but the oil coming out from the throtle and inside to the air filter, is it oke? Or i have to shut down the other one
Dont you need vacuum to pull the NOx gasses?
I dont have any filter or tube for PCV for a year It is a big problem?
It's also designed to stop condensation build up in your engine and water us a by product of burning petrol. without a pcv oil changes need to be done more regularly
hey where can i buy the filter and other pieces for it from and the plug
by adding the PCV delete filter, how do we know it's letting air out and not taking in air? (is it possible it messes up a vacuum somehow?) I'm new to this so please help me. I know this is an older video but I hope someone will respond? and can you do this on any car even if it isn't running boost? like just an average car not a sports car?
What adapter hose did you use?
Do you have to have a cool intake in or can you just do it with your stock intake and you don't have to change it
No you can do this with a stock intake :)
+milanmastracci I have a 04 Accord euro (2.4lt engine) similar to yours, and was wondering if you knew where the PCV valve is, we couldn't find it, we were thinking it might not have it considering its a 04 any info thanks bro.
So its that okay on the smogtest?
Can I get your old pcv hose I need it for my 2000vw golf
Can i install a breather even if my air intake is stock?
Were did you got the plug
Will oil drip from that little filter
I don't think that is legal in California, where I'm from..Will that pass smog or is it for off road use only🤔?
do we need to retune after doing this delete?
Can you do a video on blow off valves
nice dish washer hose you got there
can you do this with a catch can and if you can how would it be installed
The "PCV" valve you have modified is not in fact the valve, that is the fresh air into the motor while the car is idling or a cruise, any pipe to the crank case BEFORE the throttle plate is the inlet of fresh air first filtered by the air cleaner. The PCV Valve or orifice is plumbed AFTER the throttle plate so it can get vacuum to open it at idle and cruise, then closed or unused at engine WOT, literally install a catch can at the PCV Valve side first (that you haven't show) to collect oil, then if you want install a inline catch can for the clean air intake you have taken off, or don't fuck with an engine if you don't know what you are talking about.
I think your last sentence Toby pretty much sums up the situation here.
Last sentence ftw
The last sentence says it all. If someone does not have some levels of mechanical knowledge, some KZhead video will mislead them and get them into big problem.
what if after installing a shit ton of oiling is leaking from the filter... like literally splattering and leaking everywhere....?
