Can fuel build up in the PCV Valve hose if so , what would cause this to happen ?

[@MrMajintiger]

once you fix the valve should you change your oil.. mine smells of fumes or just run it and let it correct the mixture?

[@PeterWiernicki]

Thank you for explaining how a PCV valve works and showing how to replace it. You guys make really informative videos.

[@soniasias6226]

I just replaced mine because after the inspection at the dealership, I saw a yellow and red mark on it. So far I've noticed my car doesn't make a flutter sound when I climb a hill. The also marked my MAF but that's 300 dollars to replace. You explain things perfectly. Thank you.

[@mattdathew2794]

men thanks for the good info, I will be replacing mine soon as I have a lot of oil leaks

[@martinterence1841]

Who cares about what he says....at least his doing a good job so that people who don't really have any idea about fixing their vehicle will learn from him...... Good job brother....🙏👍

Thank you. Very helpful.

[@commentcrafter4158]

Great video thank you, but WHY would a stuck open pcv valve cause VACUME LEAKS?

[@AbcAbc-ox6pg]

Exactly what I thought, I don't understand as well.

[@Ogknav]

Defintely stuck open. Thanks guys!

[@manny7318]

Much appreciated for this information.

I'm fed up of my EP6C Vti 120 I'm about to replace the pcv that's no problem, however I'm going to clean the vvt solenoids too would you recommend an engine flush and oil change first?

[@minervamercado7873]

Dude, I love your site, it Is very knowledgeable, but let me ask you, why do you use the word GUYS so many times? I'm not criticizing your technique, I'm only curious guys. Love your channel, keep up the great work.

Can it blow white smoke im going thru this

[@martinburbridge7545]

I have a broken pcv hose I have found on my mini cooper 06 car was running fine I believe it is that is causing it to over fuel emit alot of smoke from exhaust I am here for a answer to this as the symptoms sound like what I have going on 😉

Can a bad pcv valve can cause misfiring

[@kushan999]

I have honda Acty 660cc Van, once you sed every vehicle has a PCV Valve but when I check the PCV valve in my vehicle does not exist just only hose going from tappet cover from the air outlet. I think it just came like that. can you explain this technique?

I love you guys thanks

This guy really does sound like Skeeter from Muppets but I like it.

[@dfields9511]

Gr8 vid. I just replace pcv valve on a 2001 maxima. It likely has never been replaced in 20 years. It’s a bit more involved when the pcv valve is soo brittle and it’s hose just snaps like plastic but worse is when it broke off it fell inside valve cover. Several hours later and new intake gaskets got the broken part out. Replaced pvc and it’s grommet on valve cover . Hopefully the oil consumption is reduced. Few days later developed p505 error. But that looked like it was a air leak on the intake hose which was cracked. Replaced that and it hasn’t come back. I may have to do the Nissan relearn procedure for throttle body. Also just changed oil so I can tell how much oil is being consumed 2001 maxima , 215k miles Oil filter 10w30 high mileage 1qt oil stabilizer substituted for oil At205 to help with rear main seal leak.

[@Bigtexbbq]

I appreciate your warning about the pcv valve potentially being brittle.

[@newsgetsold]

I am getting air coming out of the dipstick tube and the filler cap when running. Is this a symptom of bad pcv valve?

[@tubetime39]

I say yes

[@daleztoogood]

Please help.your videos not covering my truck . I can not find my pCV . I have a ranger thunder xlt 2.5td 2004 I think wlt3 engine. I only have 2k revs. And wont drive above 50mph

[@559caliii]

Can a pcv valve cause trouble if it went inside the breather box on a honda civic? It broke and half of the valve went inside?

[@byronlarios5139]

Thanks for the video. I am experiencing most of the symptoms you described, however, I see white smoke coming out of the exhaust and not black smoke. Is that a possibility for a bad PCV valve? Thanks again!

[@TheXTCNinja117]

White smoke is cause by the burning of coolant.

[@shimmyshimmy96]

Change top gasket

[@davidrichardson8934]

Love ur work great videos keep up good work dont worry bout negitive remarks from ass11oles

[@tatortottv4605]

Love how everyone has said that the PCV valve is a few dollars but the one I bought was $34 lol…

[@taab7]

If blow-by pressure builds up in crankcase then why is pcv located on top of valve cover and not on crank-case in most cars? Does the the blow-by pressure travel freely from the crankcase into the top of the engine before needing to be vented?

[@richardking6066]

Yes, most definitely.

[@tubetime39]

Oil is needed up top there and there are oil holes or channels for the oil to drain back down to the oil pan/crankcase to be recirculated and the crankcase pressure can pass up through those holes in the engine block to the valve covers where it is easier to put the PCV valve.

[@bulbul3188]

does diesel engine have pcv valve? sir

[@gallosdoro2499]

Will a bad pcv valve cause code p0420?

[@KevinJackson1]

If it is stuck open and it is creating a vacuum leak strong enough to create suction when removing the oil fill cap, could that cause a compression problem on one of the cylinders?

[@ArianaTheDopest]

This is what I want to know my cylinder two is taking a dump

[@theon_ean_donly]

A sneaky mechanic trick me into an engine rebuild, when the problem was just that little valve

[@soniasias6226]

It's sad.

[@danthetoolman4311]

What car is that ?

[@rapidtransit8373]

Its not as easy as he shows. There's a clamp on the hose that you will have to push open with a pair of pliers. Then push the hose off with a screwdriver.

[@MohammadShahid-ji4gn]

Can a bad pcv valve stall car in hot temperatures ?

[@lendavidhart9710]

It may be possible, I'm not a mechanic but my vehicle would seem like it wanted to stall out, and it would buck a little going up any incline.... Edit/added, and "back fire" up hill/incline once-in-while.

[@lendavidhart9710]

Mohammad, I just changed mine out..... I will let you know how it works now.....

[@lendavidhart9710]

Mohammad, maybe a little better, idles quiter/smoother, but still chugs up hill, I hope that helps

[@MohammadShahid-ji4gn]

@@lendavidhart9710 Thanks for the info. Actually my car was stalling, loosing power ( mostly in hot summer days ), and if i parked in sun for few hrs then it wont start. Some mechanics said change fuel pump so i did but the problem won’t go away. But after some digging i replaced my pcv valve and boom , it was fixed. I checked my old pcv valve and it was damaged. It was stuck open. I tested it with 12v battery and found out it wont work. Was stuck open. Kinky note that if PCV valve is faulty/ not working, it will not throw any codes on OBD scanner.

[@lendavidhart9710]

@@MohammadShahid-ji4gn ok thanks Mohammad, good talking to you....

[@richardking6066]

I think I can see why idling would be affected by excess air, if the valve was stuck open, and allowing air into the manifold after the MAF. But I'm not sure I can see why more oil should flow out if the valve is stuck open, than when it is operating normally - ie opening all the time there is suction on the valve. (Through increased revs causing a lowering of pressure in the manifold after the valve body) !!

[@rogerthat6221]

The oil is consumed from the pressure control valve. Hi crankcase pressure will cause oil to push past the rings and through the vent which sends it in the intake to be burned

[@commentcrafter4158]

@@rogerthat6221 this question was not regarding a stuck closed pcv valve where pressure is allowed to build in the crank case. This question was regarding a stuck OPEN pcv valve where pressure does NOT build up in the crank case and does not force oil through the piston rings. The question was, with the pcv valve stuck OPEN, WHY is more oil pushed through the pcv valve and hose into the intake manifold? Also Why would this cause a vacume leak? Their is pressure in the crank case from "blow by", pushung exhaust gases into the intake manifold when the valve is functuining normally. So why why do you even need a one way valve there in the first place? Why not just have an open tube going into the intake maifold?

[@commentcrafter4158]

What would happen if you just had an open tube going into the intake manifold with the absence of a "one way" pcv valve in the system? My car does not have a MAF sensor, only a so called "boost sensor" located in the throttle body directly behind the butterfly valve that is the throttle. The boost sensor measures the air pressure of tbe intake passed the throttle body and then the computer probably also measures the intake temperature and it can use the readings to calculate how much fuel it need to add. It is kind of like a MAP sensor, which where used before they had MAF sensors. So my question is a good question right? I do not understand why there needs to be a one way valve there.

[@tubetime39]

R King my guess is that the higher flow of air takes a little more oil with it. Only a guess.

[@withapulse2000]

@@commentcrafter4158 I was thinking exactly the same as you. The open tube design is the norm on older cars to vent crankcase gases and as long as the engine is venting the blow-by fumes that is all that matters surely?

[@ronnorris7821]

Please slow down your talking ,can't keep up with you.

[@repsgsongs4562]

What do you mean pcv valve stuck open, pcv vqlve is suppose to suck air in the engine from the intake manifold, if you remove the hose of a pcv valve your engine will die

[@carlschroeder6811]

PCV valves are metered, when fully open they are passing much less CFM than an open line. PCV valves are partially open at idle due to high vacuum, if it was stuck fully open at idle it would cause a rough idle, however nothing like a open line. At cruising speeds where there is less vacuum, the increased crankcase pressure overcomes the spring pressure and opens the valve.

[@AnythingEverythingGh]

@@carlschroeder6811 is it a one way valve or two way ?

[@carlschroeder6811]

@@AnythingEverythingGh One way, flow is always from crankcase to intake.

[@AnythingEverythingGh]

@@carlschroeder6811 Ok, so slight opening flow from the intake back to the crankcase is acceptable or IS NOT ACCEPTABLE, its a bad PCV rather?

[@carlschroeder6811]

@@AnythingEverythingGh I don't know how that would happen, the CC side always has more pressure than the intake side when engine is running. I suppose with the engine off, if you were to manually blow air through the PCV valve toward the CC as a test, a good clean valve would allow minimal air flow. Just replace the PCV and be done with it.
