Thank you 1A Auto and Sue!! My wife's 2006 Ford Focus wagon was throwing random P0171 "lean bank" codes and then it started stalling at idle. I followed the instructions in this video, the manifold gasket video, and one from Craig's DIY Car and found a 1.5 inch crack in the PCV hose. - Don't drain the coolant unless you need to replace the coolant hose that runs past the PCV hose. - You can get the bottom bolt on the manifold without lifting the car. - The Focus manual says remove the fans and shroud. I didn't. But I did unbolt the fuel rail and pop the injectors and move the rail to get better access to the clip on the PCV hose. I was able to leave the fuel line connected. - I found a rare-earth magnet that fit in my 10mm socket. No more dropped bolts. - You need the extra long angled needle-nose that Sue uses like a surgeon's forceps. - Where Sue just presses on the electrical connector for the Intake Manifold Runner Control actuator, I had to use a right angle gasket pick at the top of the latch. - The PCV valve retainer ring cracks easily. Carefully pry up - and out - at the right locking tab with a thin tool.
this woman knows the Mazda6 very well, and has put many men I know to shame. I've learned so much from watching her videos, and I've been able to do everything myself on my 07 Mazda because of her. She explains everything very well and in detail, and the camera is very clear and gets good shots of what she's doing. Sure things can be done a little different than the way she is doing it, but she is showing you the proper way to do it, and then that leads to other ways of doing things. Sometimes not doing it the proper way will work for some but not for others, so when you learn the proper way of doing things, you can branch off by doing it another way.

Grateful aya : 😉 ok... with very high mileage, get everything if you remove the intake manifold; pcv valve, water pump and thermostat, throttle body, throttle body sensor, etc. CRC cleaner products works best!
Well thanks for the video, I wonder why is she draining the coolant fluid and removing the injectors rail.. I've done this job without this unnecassary labour twice :)
@@donderfoil With tons of plastic fitting and clips inside the engine bay ( Including the whole manifold) that become brittle and break so easily. It can't be a good design. And on top, that much disassembling just to replace a simple PCV valve ? Not a smart design at all. Most cars require no more than 5 minutes to replace.
Did a PCV valve, hose, intake and throttle body gaskets on a 2008 Mazda3 with the L3-VE 2.3L engine using this video as reference. Trickiest parts were removing the PCV valve from the plastic retaining piece without breaking it (used a small pocket knife), and getting the blind center intake bolt started (wedged cardboard in socket with bolt). I didn't remove the emission tube and was able to wriggle the intake up and out without issue. Didn't drain coolant and didn't lose much on the floor. Great video, couldn't have asked for a better preview of the job!
I could not get that little round black pcv valve cover off my 2002 Ford Ranger 2.3L. In frustration was ready to break it off, instead said a prayer and found this wonderful video. Starting at the 19 min mark it shows using a screwdriver to pry it off. Thanks a bunch!

I just did this. After disconnecting the throttle body just move it out of the way doesn't need disconnecting. Also when bolting it start with 2 on top and then the difficult one in the front that way in case you drop it you can take the intake manifold off to get it out. Also don't tighten the first two bolts I said all the way so you can see from the top when bolting the porthold bolt goes in correctly. Like other person commented use tape to tape the bolt to the ratchet socket.
You are my favorite mechanic. Anytime I see a video from you I know it's going to be just what I need to do my project. My girlfriend was inspired by your mechanic skills and decided to help with the process of intake removal and reinstallation. Thanks a lot for another great video!!
+Ryan H Thank you! We love empowering our customers and showing how to perform DIY auto repairs with our high-quality auto parts. 1aau.to/m/Shop-1AAuto-c
Really wanted to thank you for putting this together. This helped tremendously in replacing my knock sensor. I only wish I had seen this about 10 years ago when I had to figure everything out myself when the PCV when out. I played it safe this time and replaced the PCV and knock sensor during this go around. Just a comment to anyone that has a Mazda 6i 2003 Automatic 2.3L. The oil dipstick is attached to the intake manifold, and surprising enough the lower nut to this is the hardest part in the beginning. Do this as your very first step right after the coolant drain. Other than that follow this awesome instructional video as shown. This is not the only video that 1A Auto Parts has put out that I have used. Keep up the good work!
What a great video. Thanks! I have a Mazda 5 2007 (European spec) and I was able to follow this with only minor differences between the models. I wont say the job was easy, but it was only really possible due to this excellent vid. I would not have attempted it if I had not come across it. Thanks again.
Thank you for another great video. You make me feel good when I see you struggle with things from time to time. You do real life videos and take your time with your step by step explanations. I am glad I found this channel and have made purchases from A1 Auto. Quality parts and reasonable prices with fast delivery.
You've done a great job here ... convincing me to leave the old PCV in and live with the consequences! One unused $6 part I will not use. Shame on Mazda for making simple servicing tasks so monumentally difficult and labor-intensive. Likewise for the alternator brushes; that $16 part has been sitting new in my glove box for 5 years since I bought the car used. The car will eventually break down far from home as a consequence.
@@WeidongYu for designing the location of the pcv how many hours to change the pcv might as well clean the throttle body while your in there I like to use silicone spray on the o rings when reinstalling
Just finished doing this today on a 2006 Mazda 3 GT. Once I removed all 8 bolts, I was able to pull the intake manifold to give 4inches of space. This gave me just enough room to remove the PCV valve off and put a new hose in. Would it have been nicer to have the extra space to take it out and replace. Yes, yes it would. However, I did not want to remove all those harnesses and having to put them back as well did not seem appealing to me. It just increases the chance for error. You also don't need to drain the coolant. You can just remove the throttle body bolts and leave it connected to the coolant lines. If you want to clean the throttle body and don't want to drain the coolant. I left the car to cool down for a while. So when I took the lines out I didn't have any coolant left inside. Also, a tip for the most head banging, stupid, idiotic design placement for a bolt for the intake manifold (center one). Have those little magnet on the extendable sticks so you can place it in the hole and turn it just enough to thread it so you can take the magnet out and leave the bolt in. Made it so much easier and less of a mess! Have fun guys! Remember, patience is immensely required. T-T
Just completed PCV/ hose & Knock Sensor, took my time 2010 mazda-6...did not drain coolant, remove injectors or jack up car! Instant improvement in MPG & cat not at threshold code gone...winter will tell! Many thanks for the video
To my understanding, you should never open the throttle's butterfly manually if it's connected to power. Disconnected from the power you should be careful but it should be fine, this way you can clean it properly. I do have a Bachelors's degree in Automotive Technology but I don't have the experience this lady has. That being said, I have properly cleaned the Electronic throttle body in my 2010 Mazda 3 2.0i and it has been 5 plus years later and working fine. This service corrected a code for Idle Air Control - RPM Lower than Expected. I have also done the same service to a 2014 Mazda 3 2.5 and it still running great. My respects to the professional lady, this is a topic I would love to examine further.
Thanks for the vid Sue just did my PCV and Hose as it was split, I use Permatex Aviation goo on the gaskets so they don't fall out and it helps seal, and for those lower bolts I used a piece of rubber heater hose that's snug on the bolt head and then guide it in once you get a couple of turns in you pull the hose off, FYI you can see into the centre lower one from the TB end of the manifold. Job done in around 4 hrs.
Me ayudo mucho, mi mazda Cx7 se oía como que chupaba aire y estaba muy temblorosa, estaba rota esa pieza, min 18:53 válvula PCV, muchas gracias eres una Master.
Outstanding video on removing it all up to the PCV valve. Detailed on how to remove the plastic retainer clip also. Thank you I will be using your video as my tutorial. I’m getting ready to do the job on my 2007 Escape.
Hola, busqué mucho un vídeo donde hagan este procedimiento y al fin lo encontré!! La PCV está muy escondida.. Mejor se lo llevo un Mecanico.. Gracias por compartir!!
Pray that your mechanic gets everything back togheter right. Is better to fix things yourself when possible. Just to make sure the job gets done right. Most mechanics are not honest and sloppy and scam people A LOT.
Nope usually its "all this" to fix the lean P0171 code that comes from the cracked rubber tube that connects the PCV to the intake manifold..That PCV valve will last a lot longer than the tube..
For the plastic ring holding the PCV valve down. If you take a pair of pliers and rotate the ring a little, it will pop right off. The little tabs move off to the side so they are not in the holes anymore. Much less likely to crack it.
I don't think there could be a better video of this procedure... I do have a question. Did you relieve the fuel pressure before breaking open the fuel rail?
It would almost be worth buying the new hose even if yours isn't in bad shape just for the brilliant clamp tabs to easily seat it when struggling with the manifold going back in lol. Great job Sue and to the person at mazda who put the knock sensor and pcv valve down there we all hate you 😅
I am sorry but the whole purpose of cleaning the valve body is to clean the gunk between the butterfly (drosselklappe) and throttle body to allow a little gap. That gap is important for the proper air/fuel mixture. You can clean the body all day long but if you don't open the butterfly and clean the walls you did not do anything. No idea how exactly the [rocesses will affect performance afterward...The battery is disconnected so the ECU will relearn and adjust the throttle. Also, it is a must to replace fuel injector O-rings when removing the injectors, just like the intake and throttle body gaskets. They may seem fine but they are cheap and if they have been there for the life of the car chances are you will run into problems later.
Ok question here I'm almost done I had already put bolts back in and was about to add fuel rail when I realized I forgot the metal emissions tube with the 22mm threads on it wellI forgot to put it back on, it just looks like a piece of metal to me, how important is it? I guess I'll have to backtrack to put it In but just wondering how nessacary that part itself is or its purpose
+dtown tx Thanks for watching! You'll want to attach all hoses back to where they go, as it could cause issues like a check engine light etc. Best bet is to back track and find where it goes!
You can change the thermostat without removing anything but the thermostat and the hose of course. Its attached to the hose housing so it needs to be replaced as a whole. Its actually pretty easy
The thermostat bolts are accessible with the intake manifold installed, but if the intake manifold is coming off anyway, change the thermostat when you have it off. If you ever want to change just the thermostat, first remove the serpentine belt tensioner. That will give you plenty of room.
Exelente, muy bien organizado, limpio y muy buena la explicación de los pasos qué se deben seguir con el cuidado que las piezas se merecen y algo muy importante que son los torques de cada tornillo y algo que me gustó también que no tiras las piezas sino todo con calma y cuidado, bravo felicitaciones . Seguiré contigo un abrazo.🔧🔩⚙️😎
Thanks for a great instructional video. I was curious if it might be possible to replace PCV valve from the bottom without removing the intake manifold? Perhaps one can remove the radiator and fan assembly to gain more room to work on the valve?
A lot of unnecessary removal going on here. I’m doing this job on a Mercury mariner and I left the rail on the engine, I didn’t pull the airbox and I did pull the cooling fans, and the job went very well. Torque spec is 156 in/lbs. it’s best to use the 1/4 drive inch pound torque wrench and go from center outward moving from top to bottom.
Great vid. Would like to know why you needed to change the PCV or knew there was a problem with it!. Not that i would attempt changing one after watching that. Think mazda thought of a PCV valve and built engine around it. Thanks
A bad PCV valve will cause various problems with most major ones, oil leaks from weak engine gaskets and seals, increased crankcase pressure which if not addressed will ruin your engine, also excessive oil consumption due to the blowby if the valve is stuck open. It is a $10 part which Toyota, for example, has right there on top of the engine and it should be replaced every two or three oil changes. Unfortunately, I see Mazda has decided to go with a retarded design. Toyota - $15 part and 2 minutes labor (0 cost if DIY and maybe $20 if the mechanic will do it). Mazda - $15 part and half a day if you know what you are doing. (probably 500 bucks in labor)
Very good detailed (to a point) video, BUT....... part numbers to purchase parts would have made this video perfect for anyone doing this (as I will be) to save time.
+Robert Bannister Thanks for watching! At this time we do not carry the PCV valve for this repair, but if we do in the future we will be sure to add a link in the description! 1aauto.com
Can I have the part numbers for the PCV hose, intake gaskets, and the throttle body gasket. I have same engine on my 2012 CX-7 sport and I couldn't find anything match on the 1Aauto website.
I was wondering isn't there some way you could get to the PCV valve and the PCV attached hose from underneath the car? It seems like you have to remove a lot of things doing it from the top.
Props to the tech👍🏼after just watching a 5 min video. on how and why to replace a pcv valve on a 5.3 vortec, an going out and accessing on my own truck within two seconds. Mazda is tripping😂
When the job was totally complete and the engine was restarted, did this initiate any fault codes and did you have to clear them or did they clear after driving the car for a period of time. In real time what time should be allocated for this job 90 minutes , 2 hoiurs, ?. Thanks John
+John Kerr Depends on the skill level. Some might be an hour. Some might be an afternoon. For us, there were no codes because this valve needed to be replaced - which we used an obdII scanner to clear codes. You can also drive around 200 miles or so for the computer to reset and the light to go away. If the light doesn't go away, there may be another issue besides a bad PCV valve
This Job will take about 6 hours Trust me. Unless you have done this before. Unless u work on cars OFTEN and know the tricks and have the confidence. . Its a challenge. I did it and its tough on your body .
Hi. Is there a way to tell that your PCV valve is not functioning properly without disassembling everything like on the video, given that it actually consumes oil (not that much but still) and you can see the oil INSIDE the intake manifold (just saw it when I took off the throttle body)? Thank you so much for the video!
now I understand why there is no vehicle theft like Mazda at least in my country to get and sell parts and units of this vehicle. The engineers who made this engine and its design should go to jail, often a problem disassembling parts to get to a tiny sensor.
Where can I buy that cap where you took off on the pvc value you said “be careful not to break it “ little black cap . Putting it back on it broke . Thank you 🥲
It is necessary to drain the coolant fluid only to remove the small hoses connected to the throttle body ?. Are there other hoses from the cooling system not shown in the video?
What I've done is kept the original PCB valve, honed it out and put extention hoses and a new PCB valve where I can access it to save me the trouble of all that work again, also add a breathable oil cap on top or make your own.azda built a great engine but put that stupid valve so low next to the oil level. The moment a little oil pressure starts to build it starts to pump oil out I to you intake costing a fortune to fix, so you would sell it and buy another new one I guess according to Mazda🤦🏼♂️
+Navdeep Singh Thanks for checking us out! We do not ship to Australia through our website, however, it is possible some parts may be shipped through eBay's global shipping program. 1AAuto.com
As helpful as it is, she did not clean around the injector and or intake area before removal, as you can clearly see, there is a large amount of debris in the injector holes as which some has surely entered. But thank you for the video.
I can't believe a maintenance part that suppose to be replaced every 50000 kms is so complicated to install...almost to take apart the whole vehicle to change that little valve...
I guess thats some mechanics that put the thumbs down on this video videos like this might run them out of business😂 only reason i could think of someone putting a thumbs down🤔🤷😂
+Efrain Macias It may be a different procedure on your application. We currently do not have an auto repair video for this particular year, make and model. Thank you for asking. 1aauto.com
It was on older 2l engines on newer so probably gen 2 mazda 3 (06 - 08 it definitely is the same as this I saw that somewhere the other day the person was shattered lol)

I am sorry but the whole purpose of cleaning the valve body is to clean the gunk between the butterfly (drosselklappe) and throttle body to allow a little gap. That gap is important for the proper air/fuel mixture. You can clean the body all day long but if you don't open the butterfly and clean the walls you did not do anything. No idea how exactly the [rocesses will affect performance afterward...The battery is disconnected so the ECU will relearn and adjust the throttle.
Also, it is a must to replace fuel injector O-rings when removing the injectors, just like the intake and throttle body gaskets. They may seem fine but they are cheap and if they have been there for the life of the car chances are you will run into problems later.
Thanks tackling this tomorrow .your video really helps me get a full understanding! Appriciate it !

Ok question here I'm almost done I had already put bolts back in and was about to add fuel rail when I realized I forgot the metal emissions tube with the 22mm threads on it wellI forgot to put it back on, it just looks like a piece of metal to me, how important is it? I guess I'll have to backtrack to put it In but just wondering how nessacary that part itself is or its purpose
+dtown tx You will need to back track and put it on.
+dtown tx Thanks for watching! You'll want to attach all hoses back to where they go, as it could cause issues like a check engine light etc. Best bet is to back track and find where it goes!
Need to replace my PCV valve and my thermostat. Will removing the intake give me access to the thermostat too?
You can change the thermostat without removing anything but the thermostat and the hose of course. Its attached to the hose housing so it needs to be replaced as a whole. Its actually pretty easy
The thermostat bolts are accessible with the intake manifold installed, but if the intake manifold is coming off anyway, change the thermostat when you have it off. If you ever want to change just the thermostat, first remove the serpentine belt tensioner. That will give you plenty of room.
@@craig853 This is a great tip, about releasing the belt , can also unbolt the tensioner, for very easy access to thermostat housing.
Exelente, muy bien organizado, limpio y muy buena la explicación de los pasos qué se deben seguir con el cuidado que las piezas se merecen y algo muy importante que son los torques de cada tornillo y algo que me gustó también que no tiras las piezas sino todo con calma y cuidado, bravo felicitaciones . Seguiré contigo un abrazo.🔧🔩⚙️😎
Thanks for a great instructional video. I was curious if it might be possible to replace PCV valve from the bottom without removing the intake manifold? Perhaps one can remove the radiator and fan assembly to gain more room to work on the valve?
A lot of unnecessary removal going on here. I’m doing this job on a Mercury mariner and I left the rail on the engine, I didn’t pull the airbox and I did pull the cooling fans, and the job went very well. Torque spec is 156 in/lbs. it’s best to use the 1/4 drive inch pound torque wrench and go from center outward moving from top to bottom.
Thanks!
This is only for the v4 model. If you have a v6 the repair is significantly easier.
Great vid. Would like to know why you needed to change the PCV or knew there was a problem with it!. Not that i would attempt changing one after watching that. Think mazda thought of a PCV valve and built engine around it. Thanks
Oil in throttle body, if pcv is restricted it can cause excessive pressure in crankcase and cause oil leaks at pan and valve cover gaskets.
A bad PCV valve will cause various problems with most major ones, oil leaks from weak engine gaskets and seals, increased crankcase pressure which if not addressed will ruin your engine, also excessive oil consumption due to the blowby if the valve is stuck open. It is a $10 part which Toyota, for example, has right there on top of the engine and it should be replaced every two or three oil changes. Unfortunately, I see Mazda has decided to go with a retarded design. Toyota - $15 part and 2 minutes labor (0 cost if DIY and maybe $20 if the mechanic will do it). Mazda - $15 part and half a day if you know what you are doing. (probably 500 bucks in labor)
@@petkoandreev7869 Very well said Sir. Perfectly explained 👌 Especially about the stupid design from Mazda.
Very good detailed (to a point) video,
BUT....... part numbers to purchase parts would have made this video perfect for anyone doing this (as I will be) to save time.
+Robert Bannister Thanks for watching! At this time we do not carry the PCV valve for this repair, but if we do in the future we will be sure to add a link in the description! 1aauto.com
Can I have the part numbers for the PCV hose, intake gaskets, and the throttle body gasket. I have same engine on my 2012 CX-7 sport and I couldn't find anything match on the 1Aauto website.
Good Video! 1A Auto always has great videos
+Mike A Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I was wondering isn't there some way you could get to the PCV valve and the PCV attached hose from underneath the car? It seems like you have to remove a lot of things doing it from the top.
Big like madam and don't stop, keep going with videos 👍🏻💪🏼
Props to the tech👍🏼after just watching a 5 min video. on how and why to replace a pcv valve on a 5.3 vortec, an going out and accessing on my own truck within two seconds. Mazda is tripping😂
+Ezequiel Ramos Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Did you replace the gaskets?
I'll never complain about removing the inlet manifold on my Ford Focus ST ever again, so much easier than that Mazda 6.
Is it absolutely necessary to drain the anti freeze?
Great teacher! Thank you
Thanks for checking us out. 1aauto.com +sabroosh
When the job was totally complete and the engine was restarted, did this initiate any fault codes and did you have to clear them or did they clear after driving the car for a period of time.
In real time what time should be allocated for this job 90 minutes , 2 hoiurs, ?.
Thanks
John
+John Kerr Depends on the skill level. Some might be an hour. Some might be an afternoon. For us, there were no codes because this valve needed to be replaced - which we used an obdII scanner to clear codes. You can also drive around 200 miles or so for the computer to reset and the light to go away. If the light doesn't go away, there may be another issue besides a bad PCV valve
This Job will take about 6 hours
Trust me. Unless you have done this before. Unless u work on cars OFTEN and know the tricks and have the confidence. .
Its a challenge. I did it and its tough on your body .
Would this be applicable to a 2004 Mazda 3 2.0L as well or are there too many differences?
What wrench are you using at 7:08? It's not listed in your tool links in the description
Thank you for this video I may use it for my fusion 2.3
SUE IS MY FAVORITE! BUT HOLY COW DOES THIS LOOK COMPLICATED! 😬
The inlet gasket, did you clean or replace? Do you have a link to one?
who can dislike a video like this
Great video! Thanks a lot!
You know or does anybody know the inner diameters of the PCV hose?
+Péter Berkes Thanks for checking us out. 1aauto.com
Would this be the same steps for a mazda 3 2010?
Hi.
Is there a way to tell that your PCV valve is not functioning properly without disassembling everything like on the video, given that it actually consumes oil (not that much but still) and you can see the oil INSIDE the intake manifold (just saw it when I took off the throttle body)?
Thank you so much for the video!
now I understand why there is no vehicle theft like Mazda at least in my country to get and sell parts and units of this vehicle. The engineers who made this engine and its design should go to jail, often a problem disassembling parts to get to a tiny sensor.
Your eyes 👀 are priceless, protect them ....
@1AAuto , is there a part # for the O-Ring that goes onto the PCV Valve? Mine snapped in half.
Thank you for the vid. I won't be doing this one lol
I’m gunna do this next week 👌 07 Mazda 3
How it went?
@@MrJesus188100 he's still doing it, he's not finished yet
Some say he’s still doing it till now ..
Mazda Xedos 6 V6 , PCV Valve change- 1 Minute. 😀
I'd rather buy a hyundai just for the pcv valve... it's on top part of the engine... no sweat to replace.

Hi there thanks for the video,,, how much is that cost to change out pcv
Where can I buy that cap where you took off on the pvc value you said “be careful not to break it “ little black cap . Putting it back on it broke .
Thank you 🥲

It is necessary to drain the coolant fluid only to remove the small hoses connected to the throttle body ?. Are there other hoses from the cooling system not shown in the video?
I cleaned my throttle body but I did not drain coolant I just used channel lock needle nose to pinch off coolant hoses worked great😀

Love Sue. Is she a tech, or an actor? Looks like a tech. Would love to talk to her about her future.

Wow, the same job on the Toyota Sienna is very simple and took less than 10 minutes.
Can anyone tell me what the special type of ratchet she uses at 7:05 is? I would love to buy one, but don't know what it's called
What I've done is kept the original PCB valve, honed it out and put extention hoses and a new PCB valve where I can access it to save me the trouble of all that work again, also add a breathable oil cap on top or make your own.azda built a great engine but put that stupid valve so low next to the oil level. The moment a little oil pressure starts to build it starts to pump oil out I to you intake costing a fortune to fix, so you would sell it and buy another new one I guess according to Mazda🤦🏼♂️
Usually PCV valves are not as complicated
+Legendary Ford Thanks for checking us out!
Is that the same procedure for a 2015 Mazda CX-5 ?
Hi, thanks for videos. They are helping me a lot. Do you ship parts to Australia?
+Navdeep Singh Thanks for checking us out! We do not ship to Australia through our website, however, it is possible some parts may be shipped through eBay's global shipping program. 1AAuto.com
Does this repair apply to the Ford Fusion 2006-2009?
sure does, and also the mazda3, but I am not sure which years
How long did it take you to do the whole thing ?
Thanks for the video. But as a non mechanic. This is where I draw the line on thigs I would and wouldn't do on my own.
As helpful as it is, she did not clean around the injector and or intake area before removal, as you can clearly see, there is a large amount of debris in the injector holes as which some has surely entered. But thank you for the video.
Do you supply parts to Scotland (Glasgow)
+John Kerr Hello! We do ship internationally through eBay. You can search for items there and then purchase. Thank you! 1AAuto.com
Wow, just to get to the PCV!
I can't believe a maintenance part that suppose to be replaced every 50000 kms is so complicated to install...almost to take apart the whole vehicle to change that little valve...
good video
Hi So I have the same model and disconnected everything properly shown, now my car is idling extremely rough what could be the cause
I guess thats some mechanics that put the thumbs down on this video videos like this might run them out of business😂 only reason i could think of someone putting a thumbs down🤔🤷😂
at arround 9:20 i see what seems to be a led inspection light..where can you buy these??
