The best explanation ive viewed..thanks much

The ultimate video about pcv system on youtube

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.

Wow what a great video explanation for both diesel and gas! My Volkswagen Jetta 2001 TDI (the ALH diesel engine) has a pcv valve on it on it btw. One of the most efficient and reliable engines ever made by VW probably. It’s definitely a valve though, I’ve taken it apart and there’s a membrane in there to make sure air only flows in one direction. It connects from the valve cover to the intake after the turbo compressor but before the intercooler. My guess as to why they thought it was needed on the diesel is because the boost pressures can fluctuate between positive and negative pressure depending on the RPM and if it’s in limp mode.

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

Thank you so much sir for all your informative videos and sharing your expertise and ideas with us.. God bless you and your family..

Great information and well presented! Thank You for putting your heart and soul into the presentation to explain the Blowby and PCV valve’s functions positives and negatives! Thank You!

The best PCV valve there is on KZfaq. I upgraded my diesel engine with a bigger turbo and was worried about the excessive blow-by and wanted to add an oil catch can but didn't get a good answer or explanation from other videos. Thank you for your videos.

U are awesome in explaining and let me tell you that I did not find this much of information on PCV system despite going thru bundle of KZfaq videos

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👌👌👌

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

Thanks for the information excellent tutorial on this topic. Keep up the great job !

The best video about PCV

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?

Thank you for this easy to understand explanation!!

What a fantastic explanation!!

Just brilliant... I am grateful to you for life for sharing your knowledge...

best video on youtube about pcv valves

Fantastic explanation, well done 👍🏻

I suggest on installing occ make sure it is ventilated well, i use occ just like you have but i make hole at the brass filter and put stainless steel wool., so far so good, make sure it is ventilated well. You’re right the shorter the hose the better.

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

Fantastic video, thank you!

Perfectly explained

Loving your work!

Wow very good information, I enjoy your video

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

wow! nice, informative content, keep it up

U are a great teacher sir 👌👌👌👌

Excellent video 👍

Outstanding !

Great presentation. 2:09 Willys Go-devil L134 for a 2 wheel drive application. This engine was one of the first to employ the PCV system on military vehicles. In the 1960's PCV's were added to civilian cars to control emissions. The PCV also prevents an engine backfire from traveling into crankcase.

Very good explanation

Thank you for sharing

Best video ever!

To make it sure, test the psi level before and after installing occ

You are the best

Thanks!

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.

Present Sir 🙋

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... 🤣 ....

My hero 👍😀👍

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.

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

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

new subs here

sir diyer....can i remove the breather hose fr. valve cover going back to intake manifold ? just because i noticed sometime when i was removed the valve cover together with the breather hose,It Has a OilMist going out to breather hose ang going through to intake manifold to combustion chamber...what if i remove the breather hose and i close the hole to intake manifold to prevent dirt air sunction.. and the other hole fr valve cover is remain open...my goal is to prevent dirt fr. oilmist going through to the throttle body... Mr.DIY...what are the Advantages and DisAdvantages....2003 HondaCrvGen2K20engineAutomaticTransmission4X2,85tkilometerRun....ty and i hope you acknowledge for my concern...Jessie fr.Philippines....

Does pcv valve has vaccum at idle?

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?

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

😊👉👍

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

Are you saying diesel engines do not have a pcv valve?

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

Hi sir My 4d56 engine is good no smoking no hard start and no oils loss but I see some oil in the air filter box com from breather pipe why?is it normal or not and how can I fix and big thanks to you and sorry my English is not good

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 ?

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

THIS IS WHY I DONT INSTALL AN OCC OR OIL CATCH CAN kzfaq.info/get/bejne/nqqoY5yn1LrQkqs.html

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

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.

Wala na. talagang overhaul nalang solusyon pla ng blowby ng 4d56 ko. L200 1997 no turbo.

WHAT IS BLOWBY? kzfaq.info/get/bejne/l7h5jNeK1byZeJc.html

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.

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

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

Every 60 seconds a minute passes You will never be alone when in the company of others If you slip and fall because the floor is slippery then you are just clumsy Two halves combined equal the total or twin halves combination Travelling 1000 metres is approximately 1 kilometre exactly Every half a kilo is 500 grams

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

You took my breath away from the song
