Your video have been incredibly helpful and encouraging for car and DIY enthusiast. Mechanics have almost damaged my mums 05 accord. Really wish I could talk to you.
Thank you for the compliment! Sorry for the experience with your mum's accord. If you want to chat offline, you can send me an email piyke@diyautoworksng.com
@@DIYAutoworksNG thanks, yeah i wanted a good dependable work vehicle so I bought a well maintained 03 Honda Accord. That plastic cruise control linkage on the throttle body breaks on those things all the time. Mine broke so I thought I was going to have to remove the throttle body to repair it but it turns out that Dorman makes a replacement kit, 977-100.
Oil consumption is a key sign. You may have oil leaks too if its stuck closed. If your car is a 2007 and you've never changed it, I won't even look for symptoms. I'd just change it. It's way overdue
Please I definitely know now that my pcv valve is bad because all the symptoms just recently started on my Honda Accord 2005 2.4L 4 cylinder engine. Please where can I buy this in Nigeria as it seems difficult to get a new one. I checked online but it can only be shipped from abroad and also most of the sites I saw has bad customer reviews about this particular product. Thanks in advance.
Many of the symptoms can also be caused by other tune up items, though you can start from the PCV valve, especially if you have never cleaned it. I really don't have a contact in Nigeria for getting a brand new one. Have you tried cleaning it extensively with carb cleaner? Does it rattle? If it still rattles you may still use it.
@@DIYAutoworksNG thank you very much for your reply. I really haven't checked if it still rattles, but since I got the car back in 2017 it hasn't been cleaned out or changed, also I wouldn't wanna believe it's ever been changed since manufacture. Anyway, I'll just change it since it's not that expensive thereby eliminating that possibility of it being responsible for the oil consumption/ seal leakages and poor fuel economy problem. Despite all these, the engine has got good power, runs and idle pretty fine and hardly gives off a "check engine" light except some minor unrelated issue which are immediately taken care of. I believe if I change the PCV it'll fix the problem, but till then, I can't be so sure.
Hello Francis, pls were u able to buy a new pcv valve? As I have cleaned up mine but the car still smokes. It’s a 2007 Honda Accord. Thanks for ur help.
@@hectordavis1900 hi. Actually, I got one and had it changed. The issues I was having before were oil leaks (from the top area seals also), and excessive oil burn. My 5ltr oil burns down to low-guage in 3months. However, after changing it, the oil leaks stopped, especially the top area, it stopped completely. But unfortunately, the oil burn continued, no effect, same rate. Well, I guess I'll have to change my oil brand and try another one as that may be the issue. If it doesn't solve the problem, I'll just live with it.
@@francisbasseyamana6878 ok thank you for the info. Currently I haven’t had any oil leaks yet just oil burns. I’ve had the car for 3years now, it recently started smoking heavily. I want to replace the pcv valve but funny enough I haven’t found it here in port harcourt. So could you let me know where you bought yours, the cost and possibly the persons contact so I could buy from them as well. Thanks.
My 05 Accord goes through about 4 quarts a week, no oil leaks, but I have recently developed a misfire problem, I got a lean misfire code so I replaced the plugs check the coils, I had a break in my intake hose I replaced that, and a new air filter. It's still missing so my next step is to check and clean the EGR valve and ports. I'm really hoping that's the problem. If not I have to get an engine compression test to make sure my valves aren't blown, fingers crossed. Any advice or prior experience with this problem would be much appreciated, I am not a mechanic
You mean 4 quarts in 200miles? That's a lot. Have you checked your radiator? Does it have any oil contamination? A PCV should definitely be among the first maintenance items for oil burn in a high mileage car.
That's still a lot for just 200 miles. It must be smoking at the back. Or, no? Clean/replace the pcv though. PCV usually last about 100k miles so it way past its limit if you never cleaned or changed it.
It's in a similar location beneath the intake manifold but this time, nearer the driver side. You can check www.hfitinfo.com/hofi-856.html for the image.
It can be replaced without an error as part of preventive maintenance. Different consensus on when to replace, but 60 - 100k miles sounds okay, except if your manufacturer lists a specific mileage.
@@hectordavis1900 I went to advanced auto parts. You can check your local auto part stores or amazon, ebay etc. Just make sure you find the right one for your car and how to install it. In most cars is easy to replace. I am definitely not letting this happen again. That single valve is the most destructive piece on any modern car. I'll be changing it more often regardless of condition. Sometimes they last forever, sometimes they don't last at all. Cheap insurance...
It is possible although more from a vacuum leak on the PCV hose as against a clogged PCV valve. What car is it? P0172 is pointing to a rich condition which can result from vacuum leaks. So apart from the PCV hose, you will need to check other vacuum hoses. In summary, a P0172 can be caused by: - Faulty or dirty MAF sensor (in equipped vehicles) - Fuel delivery issue - Vacuum leaks Since you say its intermittent, you may want to try cleaning your injectors first using a high quality cleaner. I have also seen poor quality petrol give this code.
Hmmmm it's same accord 2003. You have a point with the fuel though. I have tried to refuel from only one gas station for a while now I have just changed my intake air hose soo hopefully it'll solve it. Because i noticed multiple cracks and a major crack which i patched before had opened up unknowingly to me. I'll also clean the pcv but if it's faulty won't it throw a CEL?
@@DIYAutoworksNG Thanks. Was wondering because Google found me this... "It is likely caused by blow-by, be sure the oil level is not over full as well. It is a possibility the PCV Valve is not working properly and causing the pressure buildup as well, replace the PCV Valve first. This also may be caused by Blow-by that is caused by broken or stuck lower compression rings in turn causing the pressure to build up inside the engine, if replacing the PCV Valves doesn't stop it then get some top engine cleaner and remove all spark plugs and poor the whole can of fluid inside the spark plug holes equal amount to each cylinder, let it sit over night (spark plugs left out).
I don't think OEM is 10 bucks. Last time I went with a Beck and Arnely part, it broke while torquing it down to spec. Hadn't even reached the rated torque! Was lucky the broken part on the block wasn't too stubborn to get out. Since that experience, I only do OEM PCV valves.

thank you so much! just replaced my pcv for 07 accord. oct 2024
Glad it helped!
New sub, i just bought a 2003 Honda Accord, hoping to use it for 200k miles. Thank you
Welcome to the channel 🎉😃
Congrats on your purchase, and all the best!

Excellent tutorial. Concise and to the point.
Thanks. Glad you enjoyed it!
Using pressure air to help cleaning process
Excellent
Thanks!
What are the symptoms of faulty PCV valve? So I know when to change it. My accord is from 2007

What mileage do you cover a week? When last did you change/clean your PCV valve? Have you scanned the car?
@@DIYAutoworksNG abt 150, 200 depending. . scAnned, . lean miss code, cylinder misfire code. . probly needs pcv as well.
You mean 4 quarts in 200miles? That's a lot. Have you checked your radiator? Does it have any oil contamination? A PCV should definitely be among the first maintenance items for oil burn in a high mileage car.
A little under 2 quarts usually tops it off if I do it every 5 to 6 days, i hve a feeling the cars motor cld be toast. . 235, 000 miles.
That's still a lot for just 200 miles. It must be smoking at the back. Or, no? Clean/replace the pcv though. PCV usually last about 100k miles so it way past its limit if you never cleaned or changed it.
Good video
Thanks!
Just replace it? No vacuum problems? No software reset?
Yes. No vacuum problems except if the ends of the PCV hose are worn/cracked. No software reset is required.
You could always disconnect the negative battery terminal for 10 minutes. Then the ECU will have to relearn.
Hello please where can I buy this pcv valve
I buy them online. Amazon or hondapartsnow.com
Does the pcv valve work without the hose on IT?
The PCV valve will work. However there will be excessive oil consumption. Also venting the hot blow-by gasses underhood doesn't sound safe.
Where is the pcv valve on a 2007 fit? Thanks
It's in a similar location beneath the intake manifold but this time, nearer the driver side. You can check www.hfitinfo.com/hofi-856.html for the image.
Can it be the reason of white smoke?
White smoke is usually from coolant except you are saying white smoke with a bluish tint. In that case, it's possible.
I clean mine for fun about every 2000 miles lol
😅 I understand!
Lol nice
I'm going to start doing that
So do not replace before an error on the screen?
It can be replaced without an error as part of preventive maintenance. Different consensus on when to replace, but 60 - 100k miles sounds okay, except if your manufacturer lists a specific mileage.
You have to blow on it to make sure is not leaky
That's one way of going about it. Rattling is also good.
@@DIYAutoworksNG rattling would tell you isn't stuck. Yep, that's what happened to mine. Was leaky.
👍🏼👍🏼👍🏼
@rafa, pls where did u buy your pcv from of you have changed it am having a similar issue with mine. Thanks.

Can you use WD-40 to clean it?
No. WD-40 is not meant for breaking down carbon deposits.
WD stands for Water Displacement.
Hmmm...my pcv valve doesnt have a washer...
Is your idle smooth?
@@DIYAutoworksNG Yes
Can this also cause occasional p0172 code?

The air intake replacement may solve it. A failing PCV will need to reach a certain threshold before a CEL is thrown.
@@DIYAutoworksNG alright.. thanks
Sir do i need to disconect the negative battery in cleaning the pcv ?
Some people do, I don't.
My Honda has air coming out of the dipstick tube when the engine is running. Should I check this valve?
Usually means worn piston rings allowing blowby gases into the sump. You can clean the PCV valve though.
@@DIYAutoworksNG Thanks. Was wondering because Google found me this...

Sounds good with cleaning/replacing the PCV. Not sure of filling the cylinderw with cleaning fluid...
The amount of fools and their horns are incredible, no peace on any day. Good video though.
😅. I understand. Thanks for the compliment.
dripping dirty oil sludge all over your drive way........... SHE'S GONNA KILL YOU ! lol
For ten bucks just put a new one in.....
I don't think OEM is 10 bucks. Last time I went with a Beck and Arnely part, it broke while torquing it down to spec. Hadn't even reached the rated torque! Was lucky the broken part on the block wasn't too stubborn to get out.
