How To: Diagnose and Replace a PCV Valve
ฝัง
- เผยแพร่เมื่อ 2 ก.ค. 2024
- PCV stands for positive crankcase ventilation. The PCV system removes harmful oil vapors from the engine and prevents them from being released into the atmosphere and control the flow of the vapor from the crankcase to the intake manifold. Replacement is considered a maintenance item, so it’s important to replace the valve regularly. Some manufacturers recommend replacement as often as every thirty thousand miles.

If you’re having severe symptoms or aren’t completely sure about diagnosing this yourself, we’d be happy to recommend a professional technician in your area… But here are a few of the symptoms you might be noticing if your PCV valve is failing:
The most obvious warning signs are: smoke coming out of the tailpipe or excessive oil consumption.
If the PCV valve is stuck in the open position, it will draw excess vapors from the crankcase and burn more oil than expected.
Another clue is an engine that’s running roughly due to oil-contaminated spark plugs.
This may also be due to excessive flow from the PCV valve.
Even if your car isn’t running roughly, your oil can provide clues that the PCV valve is failing.
Check for oil spots on your garage floor… a leak could be caused by excess crankcase pressure from a clogged valve.
It’s possible this could cause gasket failure.
And when you change your oil, keep an eye out for sludge draining from the tank… it could be caused by a faulty valve allowing combustion gasses to blend with your oil.
Keep an eye out for any or all of these symptoms.
If you have a faulty PCV valve, it’s important to replace it before any other damage occurs.
For most vehicles, this is a project you can do yourself. - ยานยนต์และพาหนะ

Godbless you glasses man
Thank you. I have oil burning and every time I take my car in for oil change I tell them and they have never mentioned pcv valve. I figured it out when I changed my air flow sensor.
is your oil burning issue resolved after replacing the vavle ?

I inherited the truck from my father and I the oil change place said I’ve been burning massive amounts of oil and have my PCV check due to its never been replaced. No smoke and have great power still just massive oil consumption
Amazing video! Thank you!

That was an excellent explanation, Thanks!
$8 part and probably 5 minutes most to replace it? And my local dealership wanted to charge $300? Yeah no thank you.
What kind of car do you have? Some are sneaky and put the PCV into the intake manifold. That means replacing the entire intake manifold just to replace the PCV
Llia Olsen toyota corolla, so you could be right. I haven’t gotten around to actually replacing it yet.
David Blois hope you watched a video, it could just be like hondas and be right on top and EZ af
I still have a 1999 built Corolla and am ready to put in a new PCV and the hose as well... total cost about $22 and an hour of work on a dry day with the car engine cooled... My second one and now at 280K miles....

Very good video thank you

Thanks a lot, really useful information
Thanks for the video. Is part of the symptoms strong exhaust fumes? Not in the cab, but outside?
Thanks will check
thank you dude
I wish mine was that easy to change. Ford put it on the back of the block; close to the firewall. With my bear paw hands, it's tough to get back there! And it's in a blind spot, so you have to work by touch.🙄
Hi there GORGEOUS

If your pcv is deleted could this cause oil consumption issues?
Thanks
I bought a new fuelmeiser pcv valve and was wondering if you blow in it should it be completely sealed, the valve I bought very slowly leaks air as I blow into it is this ok or should I send it back?
Can this valve cause the vehicle to hesitate and idle roughly?
Yes
If my plugs are oily, once i stop burning oil will they clean up soon after or do they HAVE to be swapped? I just got new ones and dont wanna spend extra.
Your good
can a leak in the baffling cause burning smoke out tail pipe ?
Thanks for the explanation
Mine 99 RAV4 only smokes when I start it first in the morning and it’s not running rough either o have a ripped hose and I decided to change the pcv too but I don’t know what I’m doing lol
O'reilly had the best price compared to advanced and auto zone when I bought the valve for my tacoma 🌮

That is prob because orielly carries sketchy parts.
I noticed my pickup idling funny like it wanted to stall, took it to my local Firestone and they said it was rusty and they cleaned it up for free.
I have a 2014 Jeep Wrangler and I'm trying to find the old PCV valve so I can put a brand new one in and can you help me
I have a question, the passages side valve, on top of valve cover what is that called , I think its where the fresh air comes in, my question is can that passenger side valve be replaced i can't find a video about it, its just a hose that connects to something there on top of valve
I have a bad oil valve gasket I'm about to replace it and the spark plugs what could be causing white smoke coming out of the oil fill thank you
@ orielys auto parts
Too much blowby. From combustion chamber to crankcase. Try replacing PCV valve. They are very important and forgetten.

Replacing this costs almost $500 according to my local chevy dealership!
Do you own a newer engine or turbocharged motor? Some Chevy's have the PCV embedded inside the intake manifold. So that requires a complete manifold replacement just to fix the PCV.
@@lliaolsen728 yes, I learned that right after posting my original comment haha
Dealerships will rob you blind.
@@gregnixon1296 they sure will. one guy said my couldnt be fixed unless dealership did it. my mechanic fixed it and running great now.

What will hapen if i leave the engine without a pcv valve ?
Sx4 2013 pcv is 190k old. Oil is disappearing 2 qts every 5k miles. Is it worth trying to clean it?
A pcv valve is at most $15, it's up to you but $15 doesn't seem too much if it's brand new. It'll probably be even cheaper at some places.
Can you do a replacement on a 2012 Toyota Camry SE?
I have blue smoke coming out of my cars exhaust when taking off any idea?
If it happens during acceleration, then it's more likely bad piston rings.
There’s heaps of gunk inside where my pcv enters the engine? Is this bad and should I do anything?
Is it the same on diesel engines like GM chevy diesel?
Just paid $173 for my 2006 Honda Civic at the dealership here in Canada. (Parts $41, Labor $132)
Rip off smh 🤦 😂
My truck blows white smoke when I start it up doesn’t burn oil or coolant it’s always the same level when i check everything people told me it’s a gasket but I hope this is it
You might have a brake leak in the master cylinder and brake fluid is going into the booster
Mine is inside the valve cover. Gotta take off the intake manifold and valve cover to get to it😅
does diesel engine have pcv valve? sir
2016 Scion IA I CANNOT FIND THE PCV VALVE!

Where is the pcv valve at audi a 3 s line quattro diesel 2016 , I can't find it ? Thanks
Yeah my Lexus was throwing a little bit of smoke from the exhaust. The PCV valve was broken (if you shake it. It makes a noise. A good PCV valve stays silent) so I replaced it and my exhaust issue is gone.
On a 08 Lexus es350 you need a 19mm deep socket.
Actually a good PCV valve DOES make noise ie; rattles when you shake it! The valve has a one way mechanism that opens when letting the vapors into the manifold to burn off but stops then from going back in by preventing back flow. Most PCV valves sound make a sound similar to a can of spray paint when you shake them!
@@bigtuna9529 your right ! I was completely wrong. But my car is definitely letting off less exhaust fumes and I'd say it looks normal now and doesn't smell rich. I'm pretty sure I'm not just seeing things lol.
Anyways the PCV valve was the original so it gives me piece of mind to replace it either way.
oil has to be empty first?
Can't find the place of PCV valve of my 2007 Tucson diesel 😔

Did you ever figure it out? I’m having the same problem.
@@misstrKevin it just went away. No idea..... Grateful it did...
@@jeffreylouism don’t you just love it when that happens
@@misstrKevin Wish it never happened at all.
Symptoms but what about inspecting the part?
was just thinking that he should have shook the part to see if the ball inside makes noise or is stuck???
Clean it and blow through it both directions.it should only let air flow out
Can this cause white smoke ?
oil vapor? is it not fuel air mixture?
Nope. You should never have fuel in your valve cover. Something would be horribly wrong if you did.
Where is my PCV VALVE on my 2017 Nissan Titan XD PLATINUM RESERVE TRUCK with the Cummings turbo Diesel engine?
I have a 2015 Chev Malibu with 177000 km and it shows code 0089 and code
0016. Code 0089 says it's the fuel pressure regulator and the 0016
says it's the bank 1 camshaft position sensor. I called the dealership for the price of the FPR and they tell me they don't have one on the computer. A dummy like me believes him because I don't find any videos of anyone working on the 2015 which seems to be different than the others in the engine. Any information would be a appreciated as I have no clue where to find, even the line to fuel pressure test. Thanks
How did this turn out?? :(

Could you please show where is the exact location of the PCV valve on my 2.7 Highlander'12, 4 cyl. Images or videos specific.
Try googling it. While your there can you tell me where the valve is on my 2015 Bugatti. Thanks !
diesel engines don´t produce vaccum, so they don´t have pcv valves?
how come? they still move up and down, producing positive pressure to the internal oil chamber
I don't locate pcv valve place for sportage 2000
But wat if we don't have a garage floor
Doesnt it throw a code if faulty? I have smoke coming out my tailpipe mechanic said its a blown or cracked head.
Is it white or black?
This happened to me but mine came from somewhere in the motor
I just cleansed my pcv valve,it was blocked ,car ran rough and didn't idle great,smokey ,no power,now it runs heaps better ,they can pressure test your engine to see if blown or cracked,

Does a bad electronic PVC valve trigger a code?
no, usually there is no sensor attached - you have to check manually
It could trip the O2 sensor banks. Or throw a LEAN code.

How To Diagnose a PCV Valve? There is no way, you can only Replace it!
Andrey Yeltsov it’s supposed to only allow air to go one direction through the part
Clean it with carb spray.test it a one way valve. If it doesn't seal in the one way direction.it needs to be replaced
Mine rattles
If the spark plugs are contaminated with oil, can the spark plugs be salvaged simply by cleaning the oil on them or must they be replaced?
yes
Ya
If the plugs are fouled with oil you have big problems. Either your head gasket, or rings are not sealing. You can clean the plugs but if it fouls again you need to dig into the engine and figure out where the oil is coming from.
If you taking them out you might as well replace them. No point in trying to be cheap about it.
ive changed it 4 time in 60k miles lol
What if... I have a fuckton of crankcase pressure coming out of my oil cap.. DEFINE ANY OTHER DAMAGE- sincerely{more damage guy}
Any luck with a solution?

"Harmful oil vapours..."? There's nothing harmful about oil vapour in an engine - so, what's that malarkey about?

Toyota Camry 2006 2.4 - Weird noise after PCV Valve replacement - th-cam.com/video/XecM63P8kAo/w-d-xo.html
To understand: what force cause the PCV spring works (open/close)?... the vacuum or the pressure of the crankcase? .... because I have problem: I saw high vapor come out from the oil cap. wonder why! ..... I replaced with a after marker pcv valve 2 month ago.
some one told me maybe i have blowby problem. I know what cause too much blowby, but before go throw the piston ring I wonder if with a oil catch can can fix this.
But my question is, the pcv valve maybe is defective and no working properly to release that pressure??? PLEASE HELP !!!
You may have a blown head gasket if pressure and smoke are coming from underneath the oil cap. If the oil cap has froth on it then it is 100 percent a blown head gasket.

@@r.c.850 no problem.
@@r.c.850 a small amount of vapor coming out of your oil cap is completely normal, all engines have some amount of blowby even if its brand new
