I have been troubleshooting multiple error codes for at least a year to the point where I either wanted to catch our Tiguan on fire or put a Free sign on it. The PCB valve fixed it all! My wife treats me like a hero. I could just give you a huge hug man. Thank you for such great instructional videos.
your next engineered failure may not be as trivial... such as valve timing relatedcodes 😂 German engineers are doing their best to force drivers into buy Japanese cars... anyway it's still Bosch licensed tech regardless 👍🏻
@@glasser2819 I was thinking the same, I Like how he underplays VW parts failures, turbo wastegate,pcv, diverter valve etc. Keeps mechanics busy. Plus the magically brittle plastic german manufacturers uses is just hilarious.
Decided to buy a 2010 Tiguan w 183,000 for $1000 I'm pretty sure this is what's wrong with it can't wait to fix it and drive it love VW's!@@HumbleMechanic
+HumbleMechanic .. I just replaced it this morning. Car started doing a loud screeching noise two days ago. After checking your videos and diagnosing the problem, I ordered the part from Deutsche and replaced it myself. Very easy DYI and fix. Thank you for all the help you provide to us VW owners. (we really need it, lmao).
Great video Humble as always. A week or so ago my 2013 gti started idle revving. It would go up to over 2k rpm at stops a couple times before returning to normal. (750 rpm or so) Seeing this video and others forum posts on this problem made me think the pvc was the likely problem. Turns out my local auto store carries just the diaphragm hockey puck sized part of the pvc. So with a little work i snapped out the old and just like you mention, the diaphragm was torn. Put in the replacement and its back to normal. thanks again for your vids.
My rs5 did the same thing right after I tuned it. And I recently had one night where it took a few times to turn over and smelled like it ran lean. Unfortunately mine requires 2 and they are like $600 total. Appreciate your comment. Pushing me to check this
@@theeinsuranceguy How do you smell an engine running lean? You can smell it when it's rich, because it'll stink of fuel. But I'm not aware of a lean running engine producing any particular smell.
I put my finger over the weep hole and the pitch of the whistling changed. Any pressure applied to the cover the PCV caused the car to nearly stall. Bought the PCV, swapped it out. All is good. 45 minute job start to finish. Thank you for the great video, it saved me some $
Hi, I have just replaced mine due to smoke and a little gudder at idle, my new 1 seems to have a very strong vacuum via oil cap, also there is a slight whilst at diaphram and when I put my finger on the small hole it stops, does this sound right or have I been sold a new faulty part...
Huge, huge help. My 2010 CC had been giving me the Cylinder 3 Misfire code several months ago. I assumed it was the notorious carbon buildup and not being ready to drop the cash for repair decided to experiment with a can of Seafoam. Problem solved, no codes for 3 months! A week ago my car died while backing out of the drive one morning. No code; effortless restart. ??? A few days ago I was hit with the P2187 code and a very erratic idle. Your mention of the whistling noise struck a note with me; I'd heard that sound off and on for about a month, always at idle after highway driving. It seems you have perfectly described my issue. Parts are ordered. Thanks for saving me a lot of money at the shop.
Thanks, will include the replacement of the PCV & the hose in the next service, when the spark plugs are due anyway. Mine has 150t miles and never had issues up until this point. I heard that this part is not included in any service intervalls and can cause serious issues.
WOW!! I need to thank you so much for this video, it saved my ass. I had NO clue why my 09 Jetta Wolfsburg was screaming at me (squealing so loud), I assumed a pulley or something belt related, never heard such a consistent squealing before. We than got a bunch of misfire error codes and P0507 which lead us to you. The car has been misfiring for over a year and no dealership or shop has been able to figure out why, I kept following the symptoms and replacing coil packs. Finally a shop told me "MAYBE" it's a dirty fuel injector which is a bigger fix on the wolfsburg because you have to take apart the engine more than most other cars. Instead of going down that route we started running fuel injector cleaner at every fill up for months, it seemed to help but the car still had misfires while starting up. We were driving around and the car seemed to be driving fine than out of thin air started the loudest squeal ever, of course we were downtown and everyone was looking at us like we were idiots. Long story short the only way I was sure of the problem was by watching your video and I found the diaphragm under the pcv valve cap/cover was torn just like you said they do. The PCV valve was also very built up with hydrocarbons and oil but I cleaned it out nicely. Now I'm looking for a replacement for the cap and diaphragm. I followed forums and people are recommending the "Dorman 917-064 PCV Diaphragm Repair Kit for Volkswagen" which you can get on amazon for less than $20. Hopefully that will come soon, car is out of service until than.
Okinawapajero Glad the video helped!!! Would you let me know what you think of that repair kit? Those valves are pricey, I would love to test another solution.
Thanks for posting, it helped me. My 2009 Passat engine (1.8 TSI BZB) was shaking badly in the morning after a very cold night outside and had misfire error codes. In the end, the PVC was ok, but the crankshaft seal to the gearbox was leaking. I think the PVC froze and built up pressure. I replaced the PCV and the sealing ring as well as the clutch (reinforced version) at the same time (yes, the gearbox had to come out of course, grrr). Now the engine is running better than before. Best regards from southern Germany
Thank you so much!!!!! I went through several videos that claimed to be diagnostic, but really weren't. You just clearly answered everything I was trying to figure out... Plus the added bonus of connecting my sudden oil leak. Wish I'd known that sooner. Time to get to checking my PCV!
You really saved me towing money and expensive no use mechanics ,who have been claiming that the sound comes from a faulty pulley or a worn fan-belt. Thanks so much...
Great Video exactly the issues I was having on my Audi B8 2.0 Turbo. Replaced and runs like new. I had been using oil as you mentioned as well. Thank you Kindly !
Im here again my friend. I been working on my 2007 2.0 T FSI And everytime its a new code.since i did the valve replacment crazy but its truth I dont know the reasons but im tired to spend a tons of time on this car . The goods its you are there to show me posibles causes and how to fix the problem. Tks my friend for this videos Keep doing it .
Great guidance, thanks :-) My SEAT had a hunting idle, 'too lean' codes, and a wheezy air sound after engine off. The PCV looked a bit different, but I was able to carefully prise it apart, and voila a ripped diaphragm!
Bro you're the MAN! Cant thank you enough! My 2011 has been in and out of 2 different shops 5 times and a total of 680$ later only to have to diagnose it myself...and it was the pcv valve! Seriously thank you again I can finally SHUT THIS WHISTLE OFF! My car literally sounds like a JETSONS car
Thank you so much for the video. It saved me from going after an O2 sensor and saved my wife a lot of money. The diaphram had a torn gasket. Luckily a local part store had the Dorman part for $30. Quick and easy fix along with cheap. Thanks a ton!!
2012 GTi DSG just got Stratified Stage 2 tune now I got 2 code. Arm downpipe and Unitronic cold air intake. Been on cobb stage 2 for the longest while no problem until Stratified tune. P2187 and P050A
thanks and great video! Would a failing PCV on a 2.0 TSi cause oil consumption? I just had to add 2 quarts of oil in under 2k miles since my last oil change.
You mentioned that one of these going bad can cause oil leaks in other areas like the main seal. Once corrected does this help with those leaks or once they start you need to address those as well?
Thanx for the video . I have a golf mk5 1.4 tsi with 200 hp and i was thinking that the chain timing was of because it idle so weird. But the pcv valse was broken so that saved me al lot of work.
Thank you very much for your explanation, I was looking for a video that, in addition to showing me how to replace the part, also explains what its function is in the car engine. Thanks to you, in addition to telling me to change the part, I will be able to explain what its function is
Just bought an 07 eos w/105300 miles. Drove it a week and added 1 1/2 qts with 750 miles. Went to the dealer after google check. I think I'll just replace the pcv after watching your video. Thank you.
Am I correct in hearing you say, " The Rear Main Seal failure is in result of a Failed PCV valve?" Questions, PLEASE: 1) What is the correct VW part # for the OEM PCV valve as'y to determine what I have? 2) Will an aftermarket oil separator (that bolts on top of the engine like OEM), and catch can eliminate this issue? I just had to replace the REAR MAIN - Very expensive! I'm trying to prove your statement as it applies or not, to my 2013 GTI. Thanks for the info/video.
Got a "system lean at idle" code yesterday in my wife's 2013 tiguan. I suspected a vacuum leak. On inspection I took the engine cover off. I found that hole on the side of the PCV valve to be sucking in a bunch of air like you mentioned. I'll try the Diaphragm repair kit and see how it goes. Thanks!
I was able to replace the PCV diaphram with Dorman part number 917-064. Cost $18.00 Pried out the old and snapped in the new diaphram. Easy and stopped the vacuum leak. 2011 Audi A5 60K miles.
My 2012 GTI had surging idle just last weekend. I am pretty sure it had a highway speed (60mph) misfire for a month or so, engine check light came on Sunday,got it repaired and new valve fitted next day. 58,000 miles. Warranty covered full cost, running much better now.
My 2015 Jetta started to go thru oil. Took it to my vw mechanic told me it was this unit that got "pissed" and crapped out. Had to replace the whole unit. Doesn't burn oil anymore. Love my car. Just very touchy.
It's possible make the engine run properly without the PCV or even the Valve Cover installed. You just need to Disconnect the MAF sensor and Start the engine.
I have a 2012 Audi Q5 and I am adding a 1/2 Quart of oil every 700 miles, also noticed that the oil fill cap was super hard to remove due to vacuum pressure. I replace the PCV oil separator and still had a high vacuum pressure. Is there something that I am missing, I was told that the high vacuum pressure can cause oil loss as well. Is this true and do you have any suggestions? Thanks.
I know im a year late, but I'm going to respond because I know it'll help others. Basically, a damaged PCV can lead to higher oil pressures inside the engine, and this will eventually ruin the flimsy OEM Rear Main Seal(RMS). A ruined RMS will cause oil to leak at the junction between the engine and the transmission. The PCV is fairly inexpensive to replace and it will save you a lot more money later on. A RMS replacement is a VERY costly repair because of of how involved the procedure is. Hope this helps
Thanks for this video, it made me focus away from a suspected leaky turbo shaft. I found a fourth way the valve can fail; mine had significant carbon build-up on the diaphram and seat. After cleaning everything is back to normal.
@@uzzomuzzo1031 I haven't done much to mine yet, but I have oil leaks, engine noise, jerking when shifting gears, and more. But I actually posted this on the wrong video; I have a 2.5L MK5 Jetta (not a 2.0 engine like the one this video is for). So far, all I've done is replace the gaskets on my vacuum pump to fix my oil leak. I just did it 2 days ago but so far I think the oil leak is fixed. For now, at least.
@@kitsuvanphet8913 No, it doesn't. I've actually still neglected that issue. From what I've read online it's either because I'm low on transmission fluid, or one of the internal components in the transmission is cracked.
Hey, Charles. Great video. I'm occasionally (rarely) getting P1297 - Connection charger-throttle valve Pressure drop and P0507 - Idle Control System RPM Higher than Expected error codes. Things I've done so far: -replaced diverter valve to the newer plunger style (the original one did not have any visible holes in the diaphragm) -replaced pcv valve to cam bridge gasket/o-ring (I was told by VW that it was leaking) -replaced pcv valve diaphragm with the RKX upgraded diaphragm (the original one did have a large hole in it) -resealed cam bridge, upper timing cover, and lower timing cover (updated timing chain tensioner installed in the process) -replaced front crank seal, upper timing cover cam actuator seal and internal o-ring When the pcv valve was removed, I inspected the orange spring-loaded valve for obvious damage or malfunction. It appeared to be free of any carbon buildup and the spring still felt pretty strong. However, I didn't have a brand new one to compare it to, so I was just guessing that it was functioning properly. In terms of troubleshooting, what would be next on your checklist of things to check?
Can you tell me about the pcv that is built in to the valve cover like on my non turbo 2.0 FSI engine code BLX. I have extreme high vacuum when engine is running and cannot remove the oil filler cap unless I turn engine off. I hear a whistling noise coming from rear main seal and a very small oil leak likely from rear main seal. Engine idles rough but drives well. Do I need to changed the valve cover to fix my issue? Thanks for all your videos you make .
what causes the squeeling sound that seems to come from inside the timming chain covefr ?? my PCV diaphram is shot and am replacing it in the morning but that sound is no where near the bad part ... i thought it was the ideler bearing at first ... anywazz thanks your video solved my problem anyhow
hey thanks for all your videos. I was just wondering if a bad pcv would cause my 2008 tsi to bog down or stall if i remove the dip stick. I just replaced the rear main seal and the pcv valve 6 months ago.
I had a that code PCV.. so I just replaced it along with both hoses, and it was fine after I reset the service codes.. after several days the check engine light came in again.. so I was wondering what is causing it to come on again? Please help
Hi Charles, in your expert opinion.... Would an existing rear main seal leak stop, or lets say "leak less" once the PCV valve has been fixed? I have an original PCV valve on my 09 Tiguan, and the VW Dealership says it is still good, and not at fault for the lean, and misfire error codes. They state the rear main seal is the culprit for the check engine light.
Robert Milic Did you try changing your pcv before you fixed your rear main...if so did it stop leaking or leak less? I had my rear main replaced now leaking again....smh
Great video; just had my rear main seal replaced and now I can't boost beyond 3psi, think the PCV could be the culprit? No lean, idle or misfire codes being thrown since the RMS job. Was boosting at 17ps before I took it in (dealer confirmed they did not touch ecu).
HumbleMechanic Thanks for the fast response, it was simply a case of dealer incompetence. After receiving the car back from a full day of the dealer double checking their work & the car, I ran the codes with VCDS and it was as simple as plugging the MAP sensor back in...how they overlooked it is beyond me. But now my idle continues to fluctuate since the rear main seal and I still loose boost when I shift gears so PCV will be the next to be replaced.
Just did my timing chain in the tsi ( thanks fro the great vid @HumbleMechanic) ...0.04deg from 4.20! But I instantly got a idle lean bank 1 msg....Wondering I I screwed the PCB valve somehow.......
A failing PCV can cause also oil leaks in the turbocharger exhaust side? I have a 2.0l A4 B8 facelift 2014 (3. Gen TFSI) and my turbocharger started suddenly smoking white at the exhaust pipe. We’ve seen small streaks of oil from the turbo. Car was in the shop because of oil leakage between head and cam-housing and the PCV was also removed. I’m curious, because turbocharger had no problem before the repair... 😥 Thanks in advance!
Good vid,thx😊 my 1.8 tfsi runs great,no probs. If i lift the oil filler cap thete,s a minor vacuum. Is this good? Engine keeps running nicely without the oil filler cap. Thx again,good channel you got here 🎉
Could P0299 code be related to the PCV too? I did notice a little oil around the valve not experiencing any power issues, I do hear a little faint whistle from time to time.
+Andre Thompson It is a hand full of T30 torx and you have to remove the coils. no too bad. Be careful of the rear hose. It has a small nipple that likes to break.
Hello, after upgrading to an Integrated Engineering cold air intake I get the whistle would that be a bad PCV problem no codes are thrown off. Never had the whistle before. 2014 VW CC 2.0
Had my PCV changed last year. Oil filler cap sucks down like crazy. Now getting P12A2 code and P0171 lean code. Could too much vacuum be created? I understand there is a crankcase pressure control valve, true?
Just wondering if there has been any later revisions to the OEM PCV for the MK6 (I know the mk7 GTI seems to have an updated one...). I replaced mine back in 2016/2017, but do experience extreme smoking in autocross if I have to brake hard then turn hard left then accelerate out of a corner. So based on what I've read I probably need to add a catchcan in line too (want to keep it class legal...)
Hi, Could a faulty PCV Valve cause an Oil Pressure Warning ? I did an oil change, replaced the sensor but I'm still getting a pressure warning. I measured the pressure with a gauge, I'm at 10psi on idle, 36-40psi at 2000rpm. The reason I'm asking is because I'm hearing a veeeery small "whistle" at idle (when near the engine with the hood popped)
+Bigchuck678 I have an oil leak, I can see little oil stans in my drive way, but since the oil level is not dropping drasticly, the oil pressure seemed fine, there's no smoke and there is no knocking sounds or weird sound coming from the engine, I simply drive slower. Since I haven't got the pressure warning that often (once a week sometimes less). And I only needed to add a little bit of oil after a month to make sure I topped it off. It's not the best solution, but it works for me for now.
On the lean code instead of how some people block off the pcv vaccum/boost why not just restrict the line so it doesn’t ‘draw’ vaccuum quite so hard so it doesn’t pull oil through the main seal or other leaks.
We have a 2014 A- 4 with a 2.0 CAED and it is blowing smoke bad we have done the PCV with a factory unit and replaced the turbo and it got better for a few weeks and now it is doing the same thing I am thinking the oil rings maybe bad. Your input would be very helpful TK U
Just came across this today. Would this cause a tapping sound when it fails? My sons coil pack went out and now it taps between the #3 and #4 cylinder, right where this sits on his cc. We changed the plugs when we put in the new coil pack. The lobes on the camshaft are in perfect condition no marring or scoring. I can feel the impacts on the black plastic more than the valve cover. Any ideas?
Is this something you think should be replaced at certain mileage intervals since it's so easy to swap? Or can you still drive the car once it fails so that you can get home/dealer to buy a new one to swap?
realcyberbob We don't see failure at a certain mileage. Usually you can still drive the car. At least enough to get back home. I have seen a few that REALLY run poor due to failure.
Think I may change mine. Have some misfires dancing around cylinders. Already fixed a misfire once with new coil packs. Looked at this last night I see a bit of oil around the outside of the diaphragm. I don't think oil should be getting out of that.
Is it true, that if you take off your intake to do a carbon cleaning, and the carbon build up is moist and oily, that's a sign of a bad PVC? Recently read this somewhere, but I can't it again.
good video I think I may have to change mines my car run great no signal lights are mis fires the only problem is my car burn alot of oil I have a 2012 vw eos tsi engine 84k it's like every 600 miles are so I had to add oil the round circle piece u had in your had I do see a lil moisture from there
Would a failing pcv cause smoke coming from the exhaust? Especially on start up. I just trying to diagnose my Jetta Gli right now. Old turbo blew up so I replaced jt with a is38. Trying to figure out if it’s the pcv or just a lot of oil that leaked into my charge pipes and intercooler when the turbo broke.
2007 VW passat 3.6l doing a repair to the pcv . do you recommend a whole replacement to the cover. or on this engine being a nonturbo be ok with just replacing the diaphragm. its already a big job do not want to do this twice. thanks.
+Linh Tran I don't want to do that. Part numbers change all the time and have different applications. It's a great idea for sure. I just don't want someone to get the wrong part.
Been fighting a cyl 2 misfire. Not the plugs or coils so am pretty much at the point of replacing my pcv. Slight whistle that stops when I cover the hole but it seems to be sucking air into the hole should it be blowing out if it’s failed?
Amb1valent chaos Differnt design but works the same. Mine just shat the bed so gonna be changing it soon. Also in the process of cleaning carbon off of my intake valves!
Hi, is it the excess pressure or vacuum in the crank case that's causing damage to rear crank seal? I have just installed the updated Magneti Marelli PVC oil separator with the white top. Now i have a fair amount of crank case vacuum, it almost wants to stall out the engine when oil fill cap removed. Is this normal? Thanks for any help.
Just wondering on a 2011 GTI 2.0L turbo would a crankshaft position sensor cause the vehicle to through misfire codes and barely idle? A friends kid bought the car with 123,000 miles on it and the other night it just started misfiring and wont idle hardly at all. Should i be looking at replacing the PCV valve and hosing assembly? We did replace the plugs and coil packs and still no change. Should i also check the timing chain tensioner?
Great Video? Do you know if there is much difference between this and the 1.4L TSI engine? I have a VW Golf V GT TSI 170. Which has a faulty PCV vavle however I cant seem to find a video on it.
Hey Charles. Thanks for your videos. I have a question concerning the operation of the pcv system on the 2.0 Tfsi (BWA). If I disconnect the hose that goes to the intake manifold, should it still be vacuum in the crankcase (suction from the rear port that goes to the turbo inlet)?? If I do so on my car, I get a slight overpressure in the crankcase (I can feel it when I open the oil cap). So, I'm not sure if the crankcase vents properly when on boost... The car runs perfect, and I just complain about the oil consumption after 200.000km. Stock Pcv membrane broke at about 80.000km some years ago and I feel that oil consumption has increased since then with the new pcv. Running on 5w30 by the way. Maybe it's time to switch for a 5w40. Greetings from Catalonia.
Excellent video and information. Mine just failed. Good thing I have a second vehicle while parts come in. Def a DIY part specially if you are a little bit mechanically inclined. Save the doh!
Hey will this cause the #3 cylinder misfire?? That's the only misfire we got on our 2010 VW CC 2.0tsi Sport... I changed all ignition coils and put iridium plugs in. And it cleared alot of it up. Which is strange because the issue started one morning the car has been running fine the 3 1/2 yrs we had it. And Thanksgiving morning we start it up n it's missing n stuttering ect... I changed the plugs n coils and got the OBD2 scanner and it said all cylinders misfiring so I changed the coils n plugs n cleared the codes the engine light went off n epc light went off... Then when I started it back up after changing everything it still was missing n stuttering n hesitant on acceleration... I have no idea what's going on at this point.... It's #3 cylinder anything directly related to that certain cylinder causing it misfire n th rest be ok? N also it's been going through oil alot the through the summer .. could this lil part be the issue?? N I'm running Marvel mystery oil n gum out through the fuel n oil n gonna try sea foam to clean the carbon off the intake valves which also may be the issue. It should be ok because it's been amazing and we don't run it hard ect it's been amazing engine hopefully it'll be ok. It's.just really bugging me at this point I done spent $300+ on coils n plugs . Yup I got the absolute best coils n plugs 😂
Hi Charles, Does the Mk4 TDI have a PCV valve ? I've replaced my turbo for OEM part but still having puffs of smoke on acceleration. Checked the Inlet hoses and the intercooler and there's a lot of oil in them. Any ideas. Thank you
Need some advice I have a 2011 CC and I'm pulling misfires and codes P12A2 and P2187 do you think this could be related to pcv valve . Car idles rough in morning upon cold start .
I changed my PCV couple years ago, now I am doing the RMS, since its leaking slowly. I don't need another PCV correct? I can use the PCV I installed in the past?
I have a VW mk7 2.0 clubsport 2016 with an engine light, the trouble code is P227000 lambda probe 2 cylinder row 1 signal too lean. what do you think? A bad labda probe Or A bad PCV Valve? thanks for your response!
@HumbleMechanic given that a 2020 tiquan or vw uses the 2.0t tsi, is there a difference in engine compared to the Audi 2020 q3 2.0t tfsi? I’m not sure what the main differences are engine wise. Can you please provide a quick explanation? No one seems to know ! Thanks in advance
ive got a good question for you. first gear wont go in on a 2004 VW Golf GL TDI. no noise(grinding, etc.). and everything else is fine. would this be a fork problem or a syncro problem?
Does a 2014 Volkswagen Jetta TDI have A PCV valve? That needs to be maintenance.If so do you have a video that shows how to do it? Thank you so much for any info The reason I ask is because my engine is normally not low on oil between oil changes but now it's starting to be
thank you for all of your videos. I'm not sure if this is my problem but I just started my car and engine light came on and I have a big whooshing sucking noise at idle. it seems as if it's my prpblem. I didn't have whistling. just went straight to sucking. maybe a hose? maybe a hole in my manifold (again). I have 78,000 on it. manifold has gone every 20k so far. almost time now. going to scan it soon. see what codes I have. thanks for any input you can give me.
i noticed mine was getting a lot more oil in the front tube, i know its kind of a one way valve, come to find out air is escaping both ways. but i never got a check engine light, i guess the air did not lean it out enough for the system to detect it?
Hey Charles, Hope your doing well, what about PCV fail symptoms on the 3.6 VR6 ?, i see oil gunk on the edge of the cylinder head cover and a very subtle idle change on my 2013 Passat. Thanks in advance, take care
My new 1 is giving strong vacuum and has a slight whilst at diafram and when I cover the small hole it stops,, does this mean my brand new pcv is faulty, any help(feedback) would be much appreciated
I have been troubleshooting multiple error codes for at least a year to the point where I either wanted to catch our Tiguan on fire or put a Free sign on it. The PCB valve fixed it all!

Great video Humble as always. A week or so ago my 2013 gti started idle revving. It would go up to over 2k rpm at stops a couple times before returning to normal. (750 rpm or so) Seeing this video and others forum posts on this problem made me think the pvc was the likely problem. Turns out my local auto store carries just the diaphragm hockey puck sized part of the pvc. So with a little work i snapped out the old and just like you mention, the diaphragm was torn. Put in the replacement and its back to normal. thanks again for your vids.
My rs5 did the same thing right after I tuned it. And I recently had one night where it took a few times to turn over and smelled like it ran lean. Unfortunately mine requires 2 and they are like $600 total. Appreciate your comment. Pushing me to check this
@@theeinsuranceguy How do you smell an engine running lean? You can smell it when it's rich, because it'll stink of fuel. But I'm not aware of a lean running engine producing any particular smell.

Thanks, will include the replacement of the PCV & the hose in the next service, when the spark plugs are due anyway. Mine has 150t miles and never had issues up until this point. I heard that this part is not included in any service intervalls and can cause serious issues.
WOW!! I need to thank you so much for this video, it saved my ass. I had NO clue why my 09 Jetta Wolfsburg was screaming at me (squealing so loud), I assumed a pulley or something belt related, never heard such a consistent squealing before. We than got a bunch of misfire error codes and P0507 which lead us to you. The car has been misfiring for over a year and no dealership or shop has been able to figure out why, I kept following the symptoms and replacing coil packs. Finally a shop told me "MAYBE" it's a dirty fuel injector which is a bigger fix on the wolfsburg because you have to take apart the engine more than most other cars. Instead of going down that route we started running fuel injector cleaner at every fill up for months, it seemed to help but the car still had misfires while starting up. We were driving around and the car seemed to be driving fine than out of thin air started the loudest squeal ever, of course we were downtown and everyone was looking at us like we were idiots. Long story short the only way I was sure of the problem was by watching your video and I found the diaphragm under the pcv valve cap/cover was torn just like you said they do. The PCV valve was also very built up with hydrocarbons and oil but I cleaned it out nicely. Now I'm looking for a replacement for the cap and diaphragm. I followed forums and people are recommending the "Dorman 917-064 PCV Diaphragm Repair Kit for Volkswagen" which you can get on amazon for less than $20. Hopefully that will come soon, car is out of service until than.
Okinawapajero Glad the video helped!!! Would you let me know what you think of that repair kit? Those valves are pricey, I would love to test another solution.
Thanks for posting, it helped me. My 2009 Passat engine (1.8 TSI BZB) was shaking badly in the morning after a very cold night outside and had misfire error codes. In the end, the PVC was ok, but the crankshaft seal to the gearbox was leaking. I think the PVC froze and built up pressure. I replaced the PCV and the sealing ring as well as the clutch (reinforced version) at the same time (yes, the gearbox had to come out of course, grrr). Now the engine is running better than before. Best regards from southern Germany
Thank you so much!!!!! I went through several videos that claimed to be diagnostic, but really weren't. You just clearly answered everything I was trying to figure out... Plus the added bonus of connecting my sudden oil leak. Wish I'd known that sooner. Time to get to checking my PCV!
You really saved me towing money and expensive no use mechanics ,who have been claiming that the sound comes from a faulty pulley or a worn fan-belt. Thanks so much...
Great Video exactly the issues I was having on my Audi B8 2.0 Turbo. Replaced and runs like new. I had been using oil as you mentioned as well. Thank you Kindly !
Im here again my friend.
I been working on my 2007 2.0 T FSI
And everytime its a new code.since i did the valve replacment crazy but its truth
I dont know the reasons but im tired to spend a tons of time on this car .
The goods its you are there to show me posibles causes and how to fix the problem.
Tks my friend for this videos
Keep doing it .
Great guidance, thanks :-) My SEAT had a hunting idle, 'too lean' codes, and a wheezy air sound after engine off. The PCV looked a bit different, but I was able to carefully prise it apart, and voila a ripped diaphragm!
Bro you're the MAN! Cant thank you enough! My 2011 has been in and out of 2 different shops 5 times and a total of 680$ later only to have to diagnose it myself...and it was the pcv valve! Seriously thank you again I can finally SHUT THIS WHISTLE OFF! My car literally sounds like a JETSONS car
Mine too! 😂 Not anymore
@Bonnor Bassidy mine doesn't either anymore...I traded for a vw golf wagon. Love it.
Thank you so much for the video. It saved me from going after an O2 sensor and saved my wife a lot of money. The diaphram had a torn gasket. Luckily a local part store had the Dorman part for $30. Quick and easy fix along with cheap. Thanks a ton!!
+Jim Weck II sweet!!!!
2012 GTi DSG just got Stratified Stage 2 tune now I got 2 code. Arm downpipe and Unitronic cold air intake. Been on cobb stage 2 for the longest while no problem until Stratified tune. P2187 and P050A
thanks and great video! Would a failing PCV on a 2.0 TSi cause oil consumption? I just had to add 2 quarts of oil in under 2k miles since my last oil change.
Hi
Did you solve the oil consumption problem?
You mentioned that one of these going bad can cause oil leaks in other areas like the main seal. Once corrected does this help with those leaks or once they start you need to address those as well?
I trust you solely on your beard.
Same
Will this create a vacuum when you pull the oil cap off and change the way it runs with the oil cap off?
Thanx for the video . I have a golf mk5 1.4 tsi with 200 hp and i was thinking that the chain timing was of because it idle so weird. But the pcv valse was broken so that saved me al lot of work.
Thank you very much for your explanation, I was looking for a video that, in addition to showing me how to replace the part, also explains what its function is in the car engine. Thanks to you, in addition to telling me to change the part, I will be able to explain what its function is
Just bought an 07 eos w/105300 miles. Drove it a week and added 1 1/2 qts with 750 miles. Went to the dealer after google check. I think I'll just replace the pcv after watching your video. Thank you.
Thanks . Clear explanation , i believe mine has falled . 2015 jetta 1.8t 42,000 miles . Small valve cover leak.
Am I correct in hearing you say, " The Rear Main Seal failure is in result of a Failed PCV valve?" Questions, PLEASE: 1) What is the correct VW part # for the OEM PCV valve as'y to determine what I have? 2) Will an aftermarket oil separator (that bolts on top of the engine like OEM), and catch can eliminate this issue? I just had to replace the REAR MAIN - Very expensive! I'm trying to prove your statement as it applies or not, to my 2013 GTI. Thanks for the info/video.
I have one but think it’s failed it’s my brother in laws old build
Got a "system lean at idle" code yesterday in my wife's 2013 tiguan. I suspected a vacuum leak. On inspection I took the engine cover off. I found that hole on the side of the PCV valve to be sucking in a bunch of air like you mentioned. I'll try the Diaphragm repair kit and see how it goes. Thanks!
yup that was it! easiest fix ever. Autozone had the $30 diaphragm kit in stock. easiest fix ive had in a while
I was able to replace the PCV diaphram with Dorman part number 917-064. Cost $18.00 Pried out the old and snapped in the new diaphram. Easy and stopped the vacuum leak. 2011 Audi A5 60K miles.
My 2012 GTI had surging idle just last weekend. I am pretty sure it had a highway speed (60mph) misfire for a month or so, engine check light came on Sunday,got it repaired and new valve fitted next day. 58,000 miles. Warranty covered full cost, running much better now.
My 2015 Jetta started to go thru oil. Took it to my vw mechanic told me it was this unit that got "pissed" and crapped out. Had to replace the whole unit. Doesn't burn oil anymore. Love my car. Just very touchy.
It's possible make the engine run properly without the PCV or even the Valve Cover installed. You just need to Disconnect the MAF sensor and Start the engine.
This video was great as its given me the confidence to tackle the PCV replacememnt myself. Perth Australia
I have a 2012 Audi Q5 and I am adding a 1/2 Quart of oil every 700 miles, also noticed that the oil fill cap was super hard to remove due to vacuum pressure. I replace the PCV oil separator and still had a high vacuum pressure. Is there something that I am missing, I was told that the high vacuum pressure can cause oil loss as well. Is this true and do you have any suggestions? Thanks.
I know im a year late, but I'm going to respond because I know it'll help others. Basically, a damaged PCV can lead to higher oil pressures inside the engine, and this will eventually ruin the flimsy OEM Rear Main Seal(RMS). A ruined RMS will cause oil to leak at the junction between the engine and the transmission. The PCV is fairly inexpensive to replace and it will save you a lot more money later on. A RMS replacement is a VERY costly repair because of of how involved the procedure is. Hope this helps
Thanks for this video, it made me focus away from a suspected leaky turbo shaft. I found a fourth way the valve can fail; mine had significant carbon build-up on the diaphram and seat. After cleaning everything is back to normal.
This series has been a life saver, thank you!
Hi there , what signs exactly you had on your engine ? Please i really need a help, thank you :)
@@uzzomuzzo1031 I haven't done much to mine yet, but I have oil leaks, engine noise, jerking when shifting gears, and more. But I actually posted this on the wrong video; I have a 2.5L MK5 Jetta (not a 2.0 engine like the one this video is for).
So far, all I've done is replace the gaskets on my vacuum pump to fix my oil leak. I just did it 2 days ago but so far I think the oil leak is fixed. For now, at least.
@@Espadazorz does changing this pcv can solve jerking when shifting gear?
@@kitsuvanphet8913 No, it doesn't. I've actually still neglected that issue. From what I've read online it's either because I'm low on transmission fluid, or one of the internal components in the transmission is cracked.
Just replaced mine! Idle feels so much better and low rpm’s a lot smoother.
Thank you Humble Mechanic! Helped today so much in fixing my PCV valve and thanks for including how to test it.
AWESOME!
@@HumbleMechanic Do you recommend a pcv delete on an fsi engine
Thanks for the video but mine is VW Golf 5 TSi BWA engine and frequently cracking the oil separator. What could be the cause?
Have the whistling noise, losing boost along with a slight misfire. Replaced the diverter valve recently.
A great video ! Is it please possible to switch the pcv valve to a oil catch can?
Hey, Charles. Great video. I'm occasionally (rarely) getting P1297 - Connection charger-throttle valve Pressure drop and P0507 - Idle Control System RPM Higher than Expected error codes. Things I've done so far:
-replaced diverter valve to the newer plunger style (the original one did not have any visible holes in the diaphragm)
-replaced pcv valve to cam bridge gasket/o-ring (I was told by VW that it was leaking)
-replaced pcv valve diaphragm with the RKX upgraded diaphragm (the original one did have a large hole in it)
-resealed cam bridge, upper timing cover, and lower timing cover (updated timing chain tensioner installed in the process)
-replaced front crank seal, upper timing cover cam actuator seal and internal o-ring
When the pcv valve was removed, I inspected the orange spring-loaded valve for obvious damage or malfunction. It appeared to be free of any carbon buildup and the spring still felt pretty strong. However, I didn't have a brand new one to compare it to, so I was just guessing that it was functioning properly. In terms of troubleshooting, what would be next on your checklist of things to check?
Nice sign from my Town into the background. Greetings from Wolfsburg =)
Can you tell me about the pcv that is built in to the valve cover like on my non turbo 2.0 FSI engine code BLX. I have extreme high vacuum when engine is running and cannot remove the oil filler cap unless I turn engine off. I hear a whistling noise coming from rear main seal and a very small oil leak likely from rear main seal. Engine idles rough but drives well. Do I need to changed the valve cover to fix my issue?
Thanks for all your videos you make .
what causes the squeeling sound that seems to come from inside the timming chain covefr ?? my PCV diaphram is shot and am replacing it in the morning but that sound is no where near the bad part ... i thought it was the ideler bearing at first ... anywazz thanks your video solved my problem anyhow
thank you humble mechanic very much appreciated video. I actually want to transplant a vr6 engine in it do you have any tips?
+Michael Mendoza best tip is, get a donor car. It will cost you less in the long run.
I generally HATE VW Products but if i had to work on it your DIY videos make it A LOT more tolerable. Good work, long live the beard !
Rock on!!! they are not too bad ones you get to know them.
hey thanks for all your videos. I was just wondering if a bad pcv would cause my 2008 tsi to bog down or stall if i remove the dip stick. I just replaced the rear main seal and the pcv valve 6 months ago.
I had a that code PCV.. so I just replaced it along with both hoses, and it was fine after I reset the service codes.. after several days the check engine light came in again.. so I was wondering what is causing it to come on again? Please help
Good, Mr but I have my VW variant golf 2008 blg petrol engine makes howling noise how can I diagnose the noise from ,any basics please
Hi Charles, in your expert opinion.... Would an existing rear main seal leak stop, or lets say "leak less" once the PCV valve has been fixed? I have an original PCV valve on my 09 Tiguan, and the VW Dealership says it is still good, and not at fault for the lean, and misfire error codes. They state the rear main seal is the culprit for the check engine light.
Robert Milic Did you try changing your pcv before you fixed your rear main...if so did it stop leaking or leak less? I had my rear main replaced now leaking again....smh
Great video; just had my rear main seal replaced and now I can't boost beyond 3psi, think the PCV could be the culprit? No lean, idle or misfire codes being thrown since the RMS job. Was boosting at 17ps before I took it in (dealer confirmed they did not touch ecu).
kraigmak721 That is odd. I would not think the PCV would fail during that repair. At that low of boost, you should have a fault of some type.
HumbleMechanic Thanks for the fast response, it was simply a case of dealer incompetence. After receiving the car back from a full day of the dealer double checking their work & the car, I ran the codes with VCDS and it was as simple as plugging the MAP sensor back in...how they overlooked it is beyond me. But now my idle continues to fluctuate since the rear main seal and I still loose boost when I shift gears so PCV will be the next to be replaced.
Is air coming in through the little bleed hole normal, or does it indicate a torn diaphragm?
Thanks for ur video ... do u think bad pcv valve will trigger engine code P12a2 on vw cc?
I doubt it. It’s a fuel pressure code. I’d start with that system
HumbleMechanic thank u
Just did my timing chain in the tsi ( thanks fro the great vid @HumbleMechanic) ...0.04deg from 4.20! But I instantly got a idle lean bank 1 msg....Wondering I I screwed the PCB valve somehow.......
Thank you. With this video and the Deutsche replacement tutorial, I just successfully fixed my misfiring and vacuum leaking Audi A4.
A failing PCV can cause also oil leaks in the turbocharger exhaust side? I have a 2.0l A4 B8 facelift 2014 (3. Gen TFSI) and my turbocharger started suddenly smoking white at the exhaust pipe. We’ve seen small streaks of oil from the turbo.
Car was in the shop because of oil leakage between head and cam-housing and the PCV was also removed. I’m curious, because turbocharger had no problem before the repair... 😥
Thanks in advance!
Good vid,thx😊 my 1.8 tfsi runs great,no probs. If i lift the oil filler cap thete,s a minor vacuum. Is this good? Engine keeps running nicely without the oil filler cap. Thx again,good channel you got here 🎉
Could P0299 code be related to the PCV too? I did notice a little oil around the valve not experiencing any power issues, I do hear a little faint whistle from time to time.
not usually
Just discovered that ours is failing on our 2010 CC. was going to have our mechanic do it but you're making me think I can do this.
+Andre Thompson It is a hand full of T30 torx and you have to remove the coils. no too bad. Be careful of the rear hose. It has a small nipple that likes to break.
+HumbleMechanic I'll let you know how it goes.
Hello Charles (I hope I spelled it correctly). I hope you are doing well.
Is high vacuum in the crank case at idle normal?
Hello, after upgrading to an Integrated Engineering cold air intake I get the whistle would that be a bad PCV problem no codes are thrown off. Never had the whistle before. 2014 VW CC 2.0
Had my PCV changed last year. Oil filler cap sucks down like crazy. Now getting P12A2 code and P0171 lean code. Could too much vacuum be created? I understand there is a crankcase pressure control valve, true?
Did you change black pcv to white one?
@@laurenciogalutan91 No, my PCV was replaced by OEM PCV.
Just wondering if there has been any later revisions to the OEM PCV for the MK6 (I know the mk7 GTI seems to have an updated one...). I replaced mine back in 2016/2017, but do experience extreme smoking in autocross if I have to brake hard then turn hard left then accelerate out of a corner. So based on what I've read I probably need to add a catchcan in line too (want to keep it class legal...)
Hi charles, can you make a video about the pcv revisi0ns. Does it need a ecm flash if you are changing from black top to white top pcv.
Hi,
Could a faulty PCV Valve cause an Oil Pressure Warning ? I did an oil change, replaced the sensor but I'm still getting a pressure warning. I measured the pressure with a gauge, I'm at 10psi on idle, 36-40psi at 2000rpm. The reason I'm asking is because I'm hearing a veeeery small "whistle" at idle (when near the engine with the hood popped)
I'm having the exact same issue as you. Did you find a resolution to your low oil pressure issue?
My oil pressure on the gauge measures very close to yours.
+Bigchuck678 I have an oil leak, I can see little oil stans in my drive way, but since the oil level is not dropping drasticly, the oil pressure seemed fine, there's no smoke and there is no knocking sounds or weird sound coming from the engine, I simply drive slower. Since I haven't got the pressure warning that often (once a week sometimes less). And I only needed to add a little bit of oil after a month to make sure I topped it off.
It's not the best solution, but it works for me for now.
On the lean code instead of how some people block off the pcv vaccum/boost why not just restrict the line so it doesn’t ‘draw’ vaccuum quite so hard so it doesn’t pull oil through the main seal or other leaks.
How can I get the PCV valve and where can I buy it from because I bought two from O'Reilly's and they still leaking on the top of my valve cover
We have a 2014 A- 4 with a 2.0 CAED and it is blowing smoke bad we have done the PCV with a factory unit and replaced the turbo and it got better for a few weeks and now it is doing the same thing I am thinking the oil rings maybe bad. Your input would be very helpful TK U
Just came across this today. Would this cause a tapping sound when it fails? My sons coil pack went out and now it taps between the #3 and #4 cylinder, right where this sits on his cc. We changed the plugs when we put in the new coil pack. The lobes on the camshaft are in perfect condition no marring or scoring. I can feel the impacts on the black plastic more than the valve cover. Any ideas?
Is this something you think should be replaced at certain mileage intervals since it's so easy to swap? Or can you still drive the car once it fails so that you can get home/dealer to buy a new one to swap?
realcyberbob We don't see failure at a certain mileage. Usually you can still drive the car. At least enough to get back home. I have seen a few that REALLY run poor due to failure.
Thank you sir.
Think I may change mine. Have some misfires dancing around cylinders. Already fixed a misfire once with new coil packs. Looked at this last night I see a bit of oil around the outside of the diaphragm. I don't think oil should be getting out of that.
Is it true, that if you take off your intake to do a carbon cleaning, and the carbon build up is moist and oily, that's a sign of a bad PVC? Recently read this somewhere, but I can't it again.
good video I think I may have to change mines my car run great no signal lights are mis fires the only problem is my car burn alot of oil I have a 2012 vw eos tsi engine 84k it's like every 600 miles are so I had to add oil the round circle piece u had in your had I do see a lil moisture from there
Are there any work arounds for this like a catch can setup?
Does pcv failure relate to cam-bridge valve cover leak? Would replacing the pcv slow the leak?
Would a failing pcv cause smoke coming from the exhaust? Especially on start up. I just trying to diagnose my Jetta Gli right now. Old turbo blew up so I replaced jt with a is38. Trying to figure out if it’s the pcv or just a lot of oil that leaked into my charge pipes and intercooler when the turbo broke.
2007 VW passat 3.6l doing a repair to the pcv . do you recommend a whole replacement to the cover. or on this engine being a nonturbo be ok with just replacing the diaphragm. its already a big job do not want to do this twice. thanks.
Because it's a big job, I would leak more on the cover. That's a lot of work to do it twice.
HumbleMechanic. what other concerns going back together would u look at and replace?
Good ideal is to give us all the part number too, that will be a plus and big help
+Linh Tran I don't want to do that. Part numbers change all the time and have different applications.
It's a great idea for sure. I just don't want someone to get the wrong part.
Been fighting a cyl 2 misfire. Not the plugs or coils so am pretty much at the point of replacing my pcv. Slight whistle that stops when I cover the hole but it seems to be sucking air into the hole should it be blowing out if it’s failed?
I know this is an older video but I'd be eternally grateful for a response but is this the same for the 2.0t FSI engines
Amb1valent chaos Differnt design but works the same. Mine just shat the bed so gonna be changing it soon. Also in the process of cleaning carbon off of my intake valves!
Hi, is it the excess pressure or vacuum in the crank case that's causing damage to rear crank seal? I have just installed the updated Magneti Marelli PVC oil separator with the white top. Now i have a fair amount of crank case vacuum, it almost wants to stall out the engine when oil fill cap removed. Is this normal? Thanks for any help.
Just wondering on a 2011 GTI 2.0L turbo would a crankshaft position sensor cause the vehicle to through misfire codes and barely idle? A friends kid bought the car with 123,000 miles on it and the other night it just started misfiring and wont idle hardly at all. Should i be looking at replacing the PCV valve and hosing assembly? We did replace the plugs and coil packs and still no change. Should i also check the timing chain tensioner?
Good video I was wondering if it could cause a p0068 code many thanks
Great Video? Do you know if there is much difference between this and the 1.4L TSI engine? I have a VW Golf V GT TSI 170. Which has a faulty PCV vavle however I cant seem to find a video on it.
Hey Charles. Thanks for your videos. I have a question concerning the operation of the pcv system on the 2.0 Tfsi (BWA). If I disconnect the hose that goes to the intake manifold, should it still be vacuum in the crankcase (suction from the rear port that goes to the turbo inlet)?? If I do so on my car, I get a slight overpressure in the crankcase (I can feel it when I open the oil cap). So, I'm not sure if the crankcase vents properly when on boost... The car runs perfect, and I just complain about the oil consumption after 200.000km. Stock Pcv membrane broke at about 80.000km some years ago and I feel that oil consumption has increased since then with the new pcv. Running on 5w30 by the way. Maybe it's time to switch for a 5w40. Greetings from Catalonia.
Excellent video and information. Mine just failed. Good thing I have a second vehicle while parts come in. Def a DIY part specially if you are a little bit mechanically inclined. Save the doh!
Hey will this cause the #3 cylinder misfire?? That's the only misfire we got on our 2010 VW CC 2.0tsi Sport... I changed all ignition coils and put iridium plugs in. And it cleared alot of it up. Which is strange because the issue started one morning the car has been running fine the 3 1/2 yrs we had it. And Thanksgiving morning we start it up n it's missing n stuttering ect... I changed the plugs n coils and got the OBD2 scanner and it said all cylinders misfiring so I changed the coils n plugs n cleared the codes the engine light went off n epc light went off... Then when I started it back up after changing everything it still was missing n stuttering n hesitant on acceleration... I have no idea what's going on at this point.... It's #3 cylinder anything directly related to that certain cylinder causing it misfire n th rest be ok? N also it's been going through oil alot the through the summer .. could this lil part be the issue?? N I'm running Marvel mystery oil n gum out through the fuel n oil n gonna try sea foam to clean the carbon off the intake valves which also may be the issue. It should be ok because it's been amazing and we don't run it hard ect it's been amazing engine hopefully it'll be ok. It's.just really bugging me at this point I done spent $300+ on coils n plugs . Yup I got the absolute best coils n plugs 😂
Hi Charles, Does the Mk4 TDI have a PCV valve ? I've replaced my turbo for OEM part but still having puffs of smoke on acceleration. Checked the Inlet hoses and the intercooler and there's a lot of oil in them. Any ideas. Thank you
Need some advice I have a 2011 CC and I'm pulling misfires and codes P12A2 and P2187 do you think this could be related to pcv valve . Car idles rough in morning upon cold start .
I changed my PCV couple years ago, now I am doing the RMS, since its leaking slowly. I don't need another PCV correct? I can use the PCV I installed in the past?
I have a VW mk7 2.0 clubsport 2016 with an engine light, the trouble code is P227000
lambda probe 2 cylinder row 1 signal too lean. what do you think?
A bad labda probe
Or
A bad PCV Valve?
thanks for your response!
@HumbleMechanic given that a 2020 tiquan or vw uses the 2.0t tsi, is there a difference in engine compared to the Audi 2020 q3 2.0t tfsi? I’m not sure what the main differences are engine wise. Can you please provide a quick explanation? No one seems to know ! Thanks in advance
ive got a good question for you. first gear wont go in on a 2004 VW Golf GL TDI. no noise(grinding, etc.). and everything else is fine. would this be a fork problem or a syncro problem?
Paul G May be a siyncro. If it was a fork issue, it may impact 2 gears. What about going into reverse? This may also be a shifter adjustment issue.
shifter lingage is fine, only first gear has an issue, reverse is fine, so syncros?
Does a 2014 Volkswagen Jetta TDI have A PCV valve? That needs to be maintenance.If so do you have a video that shows how to do it? Thank you so much for any info The reason I ask is because my engine is normally not low on oil between oil changes but now it's starting to be
thank you for all of your videos. I'm not sure if this is my problem but I just started my car and engine light came on and I have a big whooshing sucking noise at idle. it seems as if it's my prpblem. I didn't have whistling. just went straight to sucking. maybe a hose? maybe a hole in my manifold (again). I have 78,000 on it. manifold has gone every 20k so far. almost time now. going to scan it soon. see what codes I have. thanks for any input you can give me.
also...would I be able to drive it like this at all? at least to work tomorrow? 9 miles?
This guy is awesome thanks so much. I’ve been searching for hours and this is exactly what my problem was. It fixed it right away
i noticed mine was getting a lot more oil in the front tube, i know its kind of a one way valve, come to find out air is escaping both ways. but i never got a check engine light, i guess the air did not lean it out enough for the system to detect it?
Hey Charles,
Hope your doing well, what about PCV fail symptoms on the 3.6 VR6 ?, i see oil gunk on the edge of the cylinder head cover and a very subtle idle change on my 2013 Passat.
Thanks in advance, take care
My new 1 is giving strong vacuum and has a slight whilst at diafram and when I cover the small hole it stops,, does this mean my brand new pcv is faulty, any help(feedback) would be much appreciated
