Best explanations about PVC. valve thanks
many people who own an Audi do not realize how important this plastic detail is
Correct yes... It can pop up codes and cause bad idle'ing, your car will run lean which is initially not actually good for your car because that will cause knock and your spark plug tips will go hot... And probably a lot of extra things 😭
@@megalodononwheels But i can hear my audi pulsating at the end of the exhaust? can it be PCV ?
Thanks for this. Fixed my misfires and runs like brand new!!!!
Hey man that is freaking awesome 😎 glad i was able to help 🥳
Great job - Your show the finite details & obstacles that you run into. Thank You
thank you for the compliments. I appreciate it so much! I try to be as helpful as possible! :)
swapped out the pcv in my 2010 audi a5. turned on the engine and it ran just fine. the following day took it out for a drive and it suffered massive misfires with a check engine light, and as i was driving i thought: did not torque the bolts enough? damage a connector? was planning on removing the coil and plugs and reinstall them. opened the hood and the breather hose from the intake manifold to the pcv had popped out! i had failed to fully engage the hose to the pcv with the "latch snaps" (dont know the proper lingo). so properly secured the hose and all good. let my experience be your wisdom.
Thanks for your input! Same thing happened to me 🤦♂️ the breather hose on the PCV would not clip in properly, the breather hose was to big. Turns out I had to buy the breather pipe with it as it was just expanding over time. Also after I clipped it back I could feel my idle was not smooth. The O-ring in the breather pipe was gone, if it fell out or was sucked in I dont know, but it is also something to look out for :)
Thanks so much, I just changed mine and the car runs so smooth now, it’s like night and day. The main points that helped were blocking the holes, disconnecting the coils, oiling the seal and that hidden screw on the left under the coil harness! Thanks again!
Super glad I could help 😎💪 It can be very scary to do it... Especially if you have to drop something inside the engine while the PCV is off 🤣 but Glad I was able to help with all the little bits you mentioned... Thank you for your feedback 🙌
Thanks , great Video very detailed and slowly explaining step by step, hope Will solve my problem. Good job👍
Thank you so much for the kind words, I am Happy to hear that it will help you 😊🙌
Well done bro . Excellent job. detail video. very professional
Thank you so much! Always nice to see a comment like this ☺️
Thanks mate. The best tutorial I've ever 👍seen!!
What a great comment. Thank you. Warms my heart to know people are finding it useful :)
Thank you so much, fixed my misfires and engine shaking on passat b7 2014 like new now thank you soooooo much!
That is great news 😎💪 super glad i was able to help a bit 🥳 enjoy your car!
This pcv valve should be replaced every 5 years or 50,000 miles. Don’t waste money on a diaphragm rebuild kit .
Great video, my check engine light just came on for this
Thank you so much! And atleast now you know what it is already 😎 and how to change it 🤣 thanks for the feedback
Wahoo este es un Maestro, que da todos los detalles a conocer mañana lo voy a poner en práctica en el A4
Haha thank you. I hope this video will help you out a lot! Take your time and don't rush it :)
Great video, thanx man 😎
Thank you for the feedback 🙌
Cool vid bro. Thankss!!
Super glad I was able to help 😎🙌 thank you for the positive feedback :)
Thank you so much very professional
Thank you for the compliment :)
Thank you so much 👍🙏
Glad I could help 🙌
The old PVC systems simply relieved crankcase pressure and burned off this vaper by feeding it into the intake. This system is actually creating a vacuum in the crankcase even at idle. Even when working as designed, this system can increase the vaporizing of very hot oil. Use only the very highest quaility oils and change at shorter intervals. This new type system is everywhere on turboed engines. Burning oil increases polluting hydrocarbons, lowers octane value of fuel (this can push the engine into preignition knocking), clog engine up with carbon buildup, damage crank seals, and run engines right out of oil and kill the engine beyond simple repair. Engines were just lasting to long anyway.
Thanks for this in depth comment. I also learned a few things now. Never knew it can drop the octane and end up with knock. These A4 cars are very knock limited. Even the stock file is knocking left and right 🙆♂️
I would like to go for a PCV delete once and for all. But not just block it off but send it to a catch can 👌
I don’t think the GOAL is for the crankcase to be under vacuum. That’s the sure sign that this valve has failed and that vacuum causes problems with the seals in the engine.
Do you recommend changing the pcv breather hoses as well? Just had the mechanic change the pcv unit on my 2010 Tiguan which stopped the main oil leak, but I’m seeing that the hoses should’ve been replaced as well cause they can be clogged. Thanks!
Hi Dennis, to be Honest it is a good Practice to have changed it aswell. But I wont say it is really necessary (thats on my vehicle though). In between video shots I do spend some time and look everything through clearly and make some judgements decisions. The oil that is found in the lines are not contaminated oil that is streaming through there in big numbers. It is rather small and fairly clean. Even by the touch of it you can wipe the oil off, what I am trying to say is that it is not a place for oil to clunk up and bloke your hoses :) but because of the internet I am going to say not suppose to Clunk up 🤣👌
Just changed mine and it seems to work. Hopefully the check engine light stays off. Idling much better on stops.
Thank you. Great video
That is great news 🥳 aslong as the light qas for a lean conditio. It should be resolved now :) did you open the round plastic cover? Was the rubber damaged?
@@megalodononwheels
There was a crack on the plastic itself. The rubber seemed fine but definitely air passing through the cracked plastic
Hi, thanks for your video was really helpful. 🎉 my question is did you change de gasket that was leaking in the back? Do you have a video of it because my car is leaking in the same place to the catalytic 19:58
Ohhhhhhh that is a vacuum leak from one of the hoses at the back...
You will need to remove the hose and rub gasket maker around it and in the pipe then place it back in. Not the right way to do it but I did do this right after the video and it feels like it was 2-3 years ago and even forgotten about it.
If you do replace the parts the right way you have to change the hose and the vacuum pump, super expensive so I went the easy rout and seems to work excellent. :)
I hope this helps a bit and thank you for the comment 😊
감사합니다
English please :)
@@megalodononwheels It means "To be thankful"
Thank you so much :)
Thanks a lot bro, any link where I can order one I need also to change mine
Best will be is to go to a spare shop. I have no idea on a online shop selling them sorry 🙆♂️
Can't we just replace the round PVC Diaphragm with a repair kit? Should only take a few minutes. I really don't know, but there are videos on that and the part can be found at your local auto store.
By all means if you just want to change the Diaphragm, then go ahead with it 😎 there will be no harm 👌🙌
Bro ok we saw diagram but other part of oil seperator we need to see . I gotta open it up after replacement
What is the other things you would like to see?
@@megalodononwheels oil seperator is big but we see only diagram side, isn’t there anything’s else under that huge part ?
The Diaphragm is the part that is most likely to break. My knowledge doesn't go much further. Also there is basically just passages in there
is the one with the white top the upgraded one?
Correct yes, just watch out apparently if you have the black top and you just place the white top one on it might blow a few seals
@@megalodononwheels oh ok thanks for the info
What about the hose line that goes to the intake .is that easy to replace
Super easy, just squeez the clip on the pipe where it goes to the PCV and Manifold and then it comes off :) there is a O-ring on them, just watch for it then also if it hasn't been removed in a long time then the clip will most likely break
What about the tdi I've looked everywhere for a mk5 tdi 2.0 pvc value and nothing
I do not want to lie... I have no Idea, never worked on those engines really. A PCV can also be a small round piece, they have a lot of different forms and are not always as big as mine. So just Google a bit and try to find out :)
Does this valve design also has an oil separator built into it?
I am unsure but I could imagine it has some kind of seperator. I know there is Kits one can buy that comes with a oil catch can 👌
So what is correct oil weight for the 2018 Audi q5? 2.0? I’ve been getting mixed results , some say 0-20, 5w-40, 0w-40, 5w-30, 0w-30. What is the correct oil weight
With out a doubt you can call Audi and give them your VIN and they will inform you which one is the correct one :)
My opinion... 5W-30 for my 2.0T
Thanks for the Video!
I have a Skoda Octavia 2020 with 42000 km on it. The PCV Valve making strange noises and I have to change it.
Is it normal to have this issue after 42000km? I don't get any faulty check engine light or any faulty messages in the computer of the car.
Glad I could help 🙌
To be honnest the design is not so full proof to me. The rubber on the inside is very poor, Over time it does get weak and I think the heat it works with is also a lot for it to handle. Mine is a few years old but haven't even seen 10 000km yet and I noticed a weird whistle coming from mine already 🤦♂️ time to go with a PCV dele kit
@@megalodononwheels this is my second unit that have the same “whistle” noise and a lot suction going on when opening the oil lid, I’m changing it again on Monday. I hope the third one will be good. I’ve seen a few of them come with flaws from the factory.
I uploaded a video of 13 sec which shows the pcv valve without the plastic part between the rubber diaphragm and the spring at the head of the pcv. Weird sounds completely gone and the suction at the oil cup decreased a lot. Seems like the plastic that separate the rubber and the spring is too thick and doesn't provide a good seal. Do you think this "mod" is safe?
Unfortunately I have no idea, I went to go look at the vidro, actually commented on my gaming acc 🤣 forgot I was signed in on that acc.
But it seems like it solved your problem, when you hold your hand over the oil cap once its removed, does it blow air out? You don't want the opposite where instead of sucking you are now blowing tones of air out...
There should be a slight blow and suck, blow and suck.
But engine shouldn't shake 👌
I managed to fix the problem by opening the PCV "head" cap and removing the plastic that seperates the diaphragm rubber and the spring.
No more excessive suction in the oil cap and no strange suction or whistling noise from the PCV.
My thought is that the plastic that seperates the rubber diaphragm and the spring is too thick and therefore can't provide a good seal.
Another reason could be that the spring is too short to provide the right tension to perform a good seal.
So it's a combination of things that may produce this problem. For now, it's fixed.
I'm not sure that this "mod" is the correct thing to do from a car manufactur perspective, but it's working.
I will check the oil cap with the test you suggested. When I remove the oil cap, there is no suction but the idle changes quickly. I'll perform the test as fast as I can and close the cap again. I'll let you know about the results@@megalodononwheels
Hi, thanks for you video, I have s question, so my Audi A4 1.8 b8 is running just fine, but it has higher oil consumption, I was searching where is the leak and is the pcv valve in my opinion, the hoses that goes into the turbo is full of oil and also the one to the intake manifold, seeing your video y just have the bout because the engine runs just fine, the idle is fine, do you recommend to change the valve or maybe the oil consumption is elsewhere? Pd: I tested the compression on the pistons and are all 4 ok, thanks in advance
Hey Brother 💪 ok this topic can turn out big 🤣 my car has the same oil consumption problem and changing the PCV won't fix it 😭 how do I know? Because I changed my PCV as you saw in the hope of helping to reduce the oil consumption but no luck :( the problem with our engines is the Piston "oil" rings, so you are thinking now... But my compression is fine? Unfortunately your compression has nothing to do with the oil rings 😭 if they are bad then you will notice your car is burning oil. Best advice is to save up money like I did and buy a forge piston set with the oil ring problem that is sorted (upcoming videos 🥳), changing your oil rings won't fix the long term problem and your car will burn oil again after 50 - 100k km
@@megalodononwheels Thank you very much my brother, I look forward to your video, unfortunately I doubt to find forged pistons in my country, I hope you can put the link to purchase to import them, many successes and may God bless you.
I bought mine at KS Motorsports. They Import it to our country but maybe he can shio it to your country but you will hsve to carry the costs towards it. I Bought the Wosner and Pec set, good till 900HP. One can get the Upgraded APR bolts then it will be good till 1000hp. Message me on social media and I will give you his whatsapp number where you can talk to him and then I will send you a photo or 2 of the set I got. :)
You can also look at IE (Integrated Engineering) as they also sell thebforged pistons and Rods.
I recommend getting the rods as the word that goes around says our rods Can't handle much more than 300kw that is about 500hp before they bend :)
Do you perhaps know what the PCV unit would look like and be located on the 1.8T B7?
I do not want to lie, I am unsure. But you can maybe send me a photo of the top of the engine, maybe I can spot it for you 👌
@@megalodononwheels Do you perhaps have an email address or so that I can use or do you prefer to use this platform?
I have social media links in the description, are you willing to use them?
A bad pcv would cause the oil to mix in the coolant ?
Unfortunately not... 😭
It is probably a head gasket or a bad radiator as our radiator is a oil and water cooler.
Also if your car did overheat it might have warped the head 🤕
Hey man question where did you get those coil packs ?
These coil packs I bought locally.
But they are clamed to be R8 coils but I doubt they are. Because one can actually buy coilds that is just red on the top.
I would highly reccomend to just buy ones from lile APR, 034 motorsport, CTS and etc. Yea they sre a bit more expensive but then you know you get Quality.
These ones of mine are doing great. Never had any problems. But its just the fact that I think its a4 coils and not R8 coils
after replacing the pcv valve i dropped some oil into where the pcv valve goes is that bad? because 9 codes came up and it was 1,2,3,4 cylinder misfire codes, system lean code, and intake air system leak. help please should i take it out and reclean it or should i drive the car for a few hundred miles to get the brand new pcv valve to pick up?
Quick question. So you dropped some oil onto the valve's? That should not make any difference at all. Your oil might be topped up a bit more 🤣 I think there might be something you did not do right. Usually if there is a vacuum leak then I would cause something like that.
Maybe the pipe that goes fron the PCV to the Intake lost its O-Ring or you did not bolt it down properly. That is the only few things I can think about.
I suggest doing everything over and inspect all the piping and look for tears in it and etc.
alright i guess i’ll do it over because it’s not clearing the P2187 code. i have other codes that come up but i’m absolutely sure it’s the high fuel pressure sensor that’s causing the intake code and idle code. i will let you know once i finish up. thanks for the reply
Do let me know if you find something :)
Was this vehicle using a lot of oil, and was it using less after the repair?
Our oil problems is not coming from the PCV but from the Oil rings sadly 😭 but to awnser your Question It did not help to reduce the oil consumption in any way 😭 just sorted the Lean condition of the leaking Diaphragm
@@megalodononwheels Thank you for the reply. Working on a US spec 2017 Q3. The PCV is sucking the oil cap a lot and the Q3 is losing liter of oil in less than 1000km. I don't Audi's this late model with the oil usage complaint online. Hope this does make some difference for us.
Ojala pueda ayudarme, mi auto tira humo al acelerar fuerte y gasta aceite cuando le doy rapido, tiene buena compresion y no gasta anticongelante, mi mecanico dice que es la valvula pcv, cuando le doy de reversa el ralenti se vuelve inestable
Hi, sorry for the English.
So there can be a couple of things.
I you do the test I did in the start of the video and you have any air blowing out or sucking by that small vent then you know your PCV is faulty and then I reccomend changing it.
Sometimes it won't fix all your problems but definitely fix a few of them.
@@megalodononwheels thanks for answering
Por q mi auto gasta mucho aceite y se prende el testigo del aceite cada rato ?
I am so sorry can you please translate to english 🙏
After changing PCV valve will engine stop vibrating?
If your PCV valve was the problem then yes it will stop :) it helped my car
I have an Audi a4 and I bought my pcv valve at Amazon do you think that could be a reason why my car is still having the check engine light on
I don't think so... Usually things bought even on like Amazon and etc will work for a few days atleast 🤣 maybe there is something els the ECU is picking up.
I think the best will be is to Diagnose it and see what it says. Then take it from there :)
You can even buy the ELM327 diagnostic tool. Hooks up with your phone with Bluetooth and can scan the engine for you. I always keep it as a back up in my car for when ever you get stuck next to the road or you have the opportunity to help someone else 👌
How much was it
Holaaa...
Cómo cambiar valvula vvt. Audi a4. Año 2010...???
Haloooo, sorry I only understand English
hello i have a 2009 audi a4 quattro b8 would a bad pcv cause the check engine light to flash??
To flash, probably not but to appear yes it will as a lean condition. When the engine light is flashing what is your car doing? Is it shaking or something of that sort?
@@megalodononwheels It’ll only flash if my car is stopped and parked once i drive it my engine light will just stay on without flashing and yes it will shake. My dip stick and engine cap smelled a little like fuel.
I think the best will be to Diagnose it and see what it says, if its lean it might be the PCV. But fuel in the oil cna mean you don't really drive the car long distances, fuel gets in the oil system in cold starts and evaporate when you drive long distance, but you must take note that fuel dilutes your oil and it makes it very thin and it can actually cause harm to your car
@@megalodononwheels can i diagnose it with that obd you used.. if so where did you buy it?
If you go on facebook under market place you might get people selling it locally by you. The small dongle is a ELM327 diagnostic tool, and then the one for the Laptop is VCDS :) but you can literally buy any Diagnostic tool :) and some of them are super cheap you won't believe it lol
Will this fit a 2016 A3 premium?? The part looks the same but Amazon sayin it won’t fit 😢 I’m about to just order it cause I need my baby to run properly. Please help anyone
It won't fit unfortunately.
Sorry to get to your message now.
This is the Gen2 motor and you have the Gen3. They are not the same. You will see your pcv has a white part to it and mine doesn't, they work with different pressures when it comes to opening and closing
@@megalodononwheels brother you just saved me time & money! Thank you so much
I changed my pcv valve and now it ildes rough whenever my ac is off… any idea as to why it does that? And what can i do do fix it.
I scanned the engine for codes and nothing came up. Could it just be a faulty piece?
Did you tighten everything down properly? Is all the hoses ok? If there is any damaged parts that can cause air to leak the engine might idle rough
Sound like a vaccum leak. Its only rough on low rpm right?
A bad pcv can cause p0420? 🧐
I really doubt it as that code is for a bad Catalitic Converter... Maybe it is just getting blocked up so the flow out the catalytic converter is bad
How can you replace that other hose that connects to the PCV
Working on it atm
Which one is it, the one that goes to the manifold or the one that runs over the engine below the spark plugs?
I was changing my oil when I noticed that old oil smelled like gas. Also the oil cap smelled like gas. When I was trying to investigate that problem I noticed this suction noise and the engine feels its about to die when I open the oil cap while the car is running. And I tested it one time when the engine was still cold and the engine actually died.
I don't have any other issues, the small vent on the valve itself has no air flow when I put my finger on it, no engine light on, very smooth idle and the car drives smoothly.
Anyone has any idea what that might be?
Thanks for the informative comment. A lot of times I get comments that is half awnsered and it makes the entire process longer to try and help haha.
Initially any vacuum leak can give you the exact same symptoms like this PCV leak symptoms. Somewhere there is maybe a damaged pipe with a tear or a hole in it. When I talk about a pipe I refer to any pipe that transfers air somewhere like a boost pipe, a vacuum pipe and a few more.
It will literally need a lot of physical time to go through the pipes. I would reccomend to start with the pipe going from the PCV to the intske manifold, those pipes must have a O-ring on... Then go to the vacuum pumo at the back, usually it gets worn out and leak air there, one way to know that is because it leaks oil on your exhaust. Then go to the boost pipes and see if you can get something :)
Did you also have an oil leak before replacing the PCV? I just put an original pcv on my car. it did stop oil leak issue but right after getting a new PCV installed It gave me check engine light code p2187 which is lean condition. You think I might have a defective new pcv. When I put my finger on to the hole it does make weird noise.Any help would be greatly appreciated thanks.
Hi, yes definitely the new one must be faulty 🤔 because my old one that was broken had the lean code, and no i haven't had a oil leak, where is your oil leaking from?
@@megalodononwheels it was leaking through rear main seal. Now after changing with a new pcv. My mechanic says it has vacume air leak through rear main seal. Old pcv damaged the rear main seal which is why my car is running lean.
My personal opinion is that the first broken pcv could maybe not have released enough pressure then it could damage your seals and then your main seal could of have been the weakest and first to go, but seals won't fix itself, it will just get worse unfortunately, definitely have a look at it in the future again if it starts leaking. Also if the seal has a vacuum leak it would push air into the crank case, it will have nothing to do with the car running lean as its two separate compartments, also thinking about it, the oil pump increases the pressure in the engine to transfer the oil to the cams, it will be most likely push oil out of the seam because of the high pressure than to actually suck air through the seal
@@naumana.2316 I am also having P2187 code after changing the PCV myself. May I know how you got it resolved?
Hi my pcv has a clear top do you recomend changing it for the same or will a black top be ok
Best will be is to find out by the dealer which one is for your car. Back then when I wanted to use the white top I came across info saying that the white top holds more pressure than the black top so having a white top you can use a black top. But of you use a white top on a black top it will blow your rear main seal out and you will need to take the engine out and remove it from the gearbox to change that small seal 🤦♂️
Thank you
Hi I changed my pcv valve today and car still has a vacum suck on the oil filler cap any info as to why? I have had a smoke tolest on it and no possible pipes leaking
How bad is the suction? It is normal to have a bit of suction but not like you need to get pliers to pull it off 🤣
Also I wonder of it might not be a faulty Vacuum pump 🤔 I might be wrong but I am just throwing Ideas around. I never had to go further than the PCV to find out the problem.
Also that pipe that connects the PCV to the intake manifold has a big O ring on the inside. Just make sure it is there, if it came out your engine probably sucked it in but won't cause any damage 👌 but it will cause like an additional air leak that can cause that suction
Suction is not that bad 😅 checked the o ring before reconnecting was all ok
not sure what it could be almost as it is takin in to much air ftom somewhere then realising then sorts itself out, but i have had a smoke test so prob not that and something else
if I am pulling up to a set of lights clutch in and stop my rev ometer fluctuates up to 1.5 to 2000 rpm for few seconds then goes back down to normal idol 🤷
Did you notice,after replacing the pcv, that the idles a bit faster?
When you are talking avout faster, do you mean idles at higher RPM?
Most stock cars idles between 700 to 900rpm's, are yours higher?
Not higher but it sounds higher after the old pcv replaced. Sounds like it's the right "sound" that the engine have in terms of air to fuel ratio. Sounds like the engine is "faster" and healthier@@megalodononwheels
Ohhhh I see... That is great news then 🥳🙌...
Interesting fact, since I made this video, my "new" PCV is starting to pack up 🤦♂️ next I will rather go for the PCV Delete kit
I am trying to change PCV valve for my car, but I cannot find it. Can someone help me find it. It's Audi A3 2007 1.8 TFSI. Any help would be great. Thank you.
Please send me a photo of the top of your engine to my Facebook acc. Link in description.
Its probably on the right hand side on top of the engine. Its very long if if it is the engine I am thinking about.
Just now sent a message in FB. Cheers mate.
Is that a Q7? If not, where is the PCV valve on a 2015 Audi Q7 3.0 Premium Plus?
Hi, this is the A4 and the Petrol version, for thr 3.0 TDI I am unsure sorry, have you tried to google it maybe? Under google images
Heard it’s under supercharger 🫤
Can this fix P0171?
Yes, it fixed my P0171 code
@@megalodononwheels will try to change it. Should I disconnect the battery before doing this?
No it is not necessary :)
Hi. what oil should I use to lubricate the seal?
I just used the engine oil I had spare, mine is 5w-30
Hey I’ve an 2013 audi A6 C7 2.0t it shows me warning “turn off engine check oil level” when the oil level is OK and the warning comes and go do i have to change the pcv valve?
Hi, sorry to respond to your comment so late...
As far as my knowledge go. The PCV won't help. PCV stands for positive crankcase valve. It works with the pressure at the bottom of the block that can be high because of Blow by and a few other reasons. And not the oil pressure.
For the low oil pressure it can be your cam bridge maybe as they intend to fail alot or a oil pump that is going bad.
Please do let me know if you found something, I will be interested to know aswell :)
I bought a PCV valve but when I change it the motor shuts down. Would that be a faulty PCV valve?
So sorry for dor getting to you so late, for some reason your msg never showed. You probably already fixed it, but if I had to guess I would say yes it could be the p
PCV if the installment wqs 100%. But it can even be that maybe the PCV is not sitting flat and it might have a leak or even maybe forgotten to tighten somewhere. But if you did find problem, let me know 💪
perso i would never buy aftermarket pcv valve...
My experience was not bad at all but 8000km later mine is whistling again so it seems like the life span on them are very poor. (take note I did have a boost problem so it could have damaged the Diaphragm on overboosts 🤷♂️)
junk plastic and rubber garbage! build real cars again out of metal ! took my junk plastic intake off and found a pool of oil in my engine valley ! i get the whistle when i shut the motor off !
No way 😱 was it your PCV valve that gave in? If it is that bad then whoawh! I am definitely shocked
Same happened to me. What did you do?
I sae there is OCV delete kits for our engines. I think to avoid things like this in the future, it will be best to get one of those :)
