Positive Crankcase Ventilation Explained. PCV Valve

You took my breath away from the song

Very helpful thank you very much are you from world war 2 like you said in the movie i am from my hometown where i live can the valve be a bad connection with both of us learning magic and cast spells on them

Thank you for your video i hope it wasn't windy today and i am very ticklish but i will not kiss you on our first date unless you are a very very handsome fellow also if the topside on the corner is the valve on or near or in or close to or located across the intake manifold then are you going to tell me your secrets my secrets are very shiney and have been cursed and now i can't find them unless you are the gate keeper or my naughty uncle busy fingers and a wizard but shhh, i hope this was helpful links in the description

I have a peewee see-valves on or in or near the middle of the back and on the front side of the connection does under or with or at or it can be beside the case with the top corner near the back facing towards the intake inlet indent incence hold the spring firmly with both sides correctly while over both the top rightside of the back of the actual unit or follow this link to finish, i hope this was helpful and are you able to thank you.

Wow. thank you very much , that was a complete explanation wich answer all the questions

Wala na. talagang overhaul nalang solusyon pla ng blowby ng 4d56 ko.

L200 1997 no turbo.

This was one of the best videos I have seen, 👍

Fantastic explanation, well done 👍🏻

You are the best professor so far in explaining how PCV valve works! And also why it is called POSITIVE. Maybe you could also do a video about how to fix high oil consumption. I have a 2006 RAV4 which consumes a quart of oil for every 300 miles! It is a well known fact with 2006 to 2009 RAV4.

Thank you so much. In 2 days I learned a lot, and I happened to have a problem with my car that your videos helped me to solve. Didactic explanations, even a layman in the field would understand and can use to personally solve their mechanical problems👌👌👌

Sir i just bought a motorcycle v twin and oil is pumping through the crankcase vent, im thinking about installing a PVC at the end of the hose, is that okey ?

New subscriber!!!😊

Outstanding !

Fantastic video, thank you!

Wrong. There is a throttle valve with a complete throttle body on diesel engines too.

Loving your work!

Thanks!

You enlightning me sir.... ill subscribe you.... 👌...
Now I know the reason why my dad put the breather hose of his diesel truck into his exhaust pipe... 🤫 ... we dont have emision laws here...so its fine... 🤣 ....

Your explanations of PCV and EGR are very good. Concise and easy to understand. I make parts for engine conversions, and always recommend that customers leave these systems as they were designed to be. However, I'm also sure that many of them don't understand the function and purpose of these systems. Would you mind if I include links to these videos on my web site?

what if diesel equipped with turbo - still pcv is not required?

Wow!!!!!!!!! Very good educative video

That is a GREAT explanation. I"ve been looking for this for a long time.

What if there's a white smoke in the oil disptick? (Diesel engine)

Does pcv valve has vaccum at idle?

sir its ok to take it out ah breterhose to intakemonifold down into the transmission diesel engine my car..thnx to advice me it is god or bad to the engine

Hi,i have Fiorino 1.3 Euro5 with 75hp.I have problem , when i startup car ,engine run ok, after some minute 3-5minute i have blue smoke.I have check 3 times injector(in Bosch servise),new timing chain,new glow plugs,new DPF.Oil is always on max.Colant is ok.I have clean EGR,Intercoler,Intake manifold.When car litle get worm all is OK.Also I have buy new MAP,MAF and new oil separator.Can you please help me?Thanks

Best video ever!

U are a great teacher sir 👌👌👌👌

Thank you for this easy to understand explanation!!

wow! nice, informative content, keep it up

My 1976 alfa romeo has a factory oil seperator can. It has a small hose from the can to the intake after the throttle valves. Them there is a large hose from the can to the a cleaner (this one take over when the throttle valves are open)
There is also a hose going from the can to the dip stick tube for oil return and of coarse a large hose from the valve cover to the can. However there is no positive crankcase air going back Into the engine and there is also no pvc valve to regulate positive pressure. I assume this set up has constant vacuum.

I have a Polo 1.5tdi diesel engine. I have to remove the top plastic casing due to a breakage of a injector holder screw. I took out the screw and fitted it back. Everything is working good now. But so I have to use any paste and seal the plastic case to prevent any leakage in future. I haven't noticed any paste stains while removing.

Another question is I found diesel on top of my injector holder. But when I removed that diesel and tried accelerating on a high rpm, I couldn't find any leakage on common rail, injector input pipes or injector return pipe. I tried accelerating the car while at rest few times but can't find any leak. I found this diesel after driving for 45mins. Could you please advise on how the leakage might have happened.

Wow very good information, I enjoy your video

That's a lot of useful information. following up on my comment about OCC. My idea was to point the blowby exhaust down like you showed. Since it needs vacuum to be pulled out, what about if I did 3D printed OCC or just dump hose that would have a fan or something to pull the blowby out?

But i should still see a slight vacuum if i remove the oil cap on a diesel engine, right?

Very good explanation

Keep watching and support especially 45sec. Ads from Al Khafji Saudi Arabia 🙏

My hero 👍😀👍

idol, kng iincrease ko boost ng 4d56T mas better?

new subs here

very very good explanation sir. but may I ask what makes more carbon build up? because of EGR or Crankcase gases? or by removing either 1 and it would reduce the carbon.

😊👉👍

Excellent video 👍
