![How to Replace the PCV Diaphragm on a Volvo T5 [Money Saving Way]](http://i.ytimg.com/vi/1O4r1ftgJaQ/mqdefault.jpg)
So glad I happened by this. Replacing a cam seal that's leaking on my '06 V70. Yes! the glove filled up like you wouldn't believe. So I ordered a kit and will do it alongside my seal replacement (120K and needs timing belt anyway). It would have just started leaking again somewhere. Many thanks!
Cripes watch out folks. If the vacuum pulls this inside it quickly wraps onto everything internally and makes a bigger mess!
Just wait until you hear a squeal, the cap or dipstick becomes difficult to remove then the squeal goes away when you do lift them, followed by a woosh sound
Ok, on the volvo, and some other cars....there is a screen, and you can see that in the video. put a mason jar screen or something over the hole or something. Don't be an idiot basically
my b5024t5 has a grill over the oil filler it wouldnt get inside
Great video. Simple and to the point, with no BS . Thanks, it worked as you said.
Glad it helped Steve!
Just tried this on my 2006 xc70, 185,000 miles. Surprisingly it was sucking in. Im still gonna do the pcv system anyway. Great video sir.
Hello Vermont! I am glad it helped you out.
If pcv is your worry mine was clogged and blew the crank seal check for leaks behind timing belt
my 96 850 with 180,000kms still has vacuum
Glove almost disappeared into the oil filler hole, thanks for the video
You're welcome Michael! Your Volvo need PCV system get serviced. Let me know if you have any questions. Cheers Brotha!
@@PistonShack do you know how to fix Volvo engines if I may ask?
Hello, thanks for the tip. I have just bought a v70 awd 2.5T november 2004. I will do the same check for sure. Cheers
Glad it helped Jeroen!
Just loosen the oil cap and start the engine. The cap should not fly off. It should stay in place, pulled by vacuum. This glove thing can be bad if it gets pulled into the engine.
It won't suck glove in. Even more, Volvo oil filler neck has metal screen.
E92 with no issues absolutely sucked glove in almost to be shredded in the valve cover. lucky I laid a heavy knife on the tips of the glove before startup to give me time to get to the glove since I was doing this preventive check alone with no helper
@@CripplelovesWolly start the car then get out and put the glove on, no?
Hey thanks for the cap trick because I’m not comfortable going to the dealership and putting a rubber glove on this thing to watch it get sucked in lmao! So feel for air pushing out, got it
Great video. My engine has been knocking and squealing, tried this trick and it sucked the glove for 10 seconds but then it started to inflate and the engine started to knock
Sounds your PCV system needs service if it wasn't serviced last 50K km.
@@PistonShack I thought I'd update you on the problem, My PCV was bad and I replaced it, The PCV was 220,000 miles old but it wasn't clogged at all, I caught it at the early stage of failure, I'm sure the diaphragm was bad. I still had a knocking and squealing sound coming from the passenger side of the vehicle so I checked the pulleys and suspension and found the root cause of the noise. I did a timing belt and water pump replacement a couple thousand miles back and the 30MM crank shaft pulley nut came off at some point. The only thing holding the crank shaft pulley on were the 4 outer bolts. I got a new nut, Put thread locker on and made sure it was on tight and the problem went away. I'm glad the noise brought the bad PCV valve to my attention tho.
Hi, I just changed my S40 (2008 1.8L) PCV and Hose but after making the glove test again I can see that glove inflates the same. What might be wrong here?
i prefer blowing through the pcv tube to see if there's any resistance. Although this test works I've had cars where it passes the test but the pcv is close to getting clogged
Interesting point! Thanks Tabithia.
Very interesting test video!
Thank you! Cheers!
Just an fyi, PCV stands for positive crankcase ventilation. 😎
Thanks Walter, good point!
@@PistonShack yes sir
Thank you SO much!!!!! Great video!!
You are so welcome!
My 07 Camry inflated the glove when I ran this test. What do I do?
Just did the test after replacing the whole pcv assembly on my XC60 T6 2012 and it sucks the glove's "palm" right in...no more whistle also....however since I replaced it (with genuine Volvo part) the car has a rough idle sometimes (instead of 600 rpm it looks like its trying to balance at around 500 to 550)...i changed also all 6 coils and plugs with Mahle oem parts at the same time. Scanned the car for faults through its Obd and it shows that there is a fault with its exhaust valve..(????) Any tips on that will be highly appreciated...Trying to figure out where is this exhaust valve located and if it really is the source of the problem...The car drives perfectly fine, it hesitates a bit when cold and the gearbox is going through 1st to 2nd or 2nd to 3rd gear at low rpms (less than 1.500). Other than that it drives like new.
Hi Spiro, Always post the OBD trouble code number when you know it even if you don't know what it means.
I am almost certain your code is OBD-II Code P0027 - Exhaust Valve Control Solenoid Circuit Range/Performance because that's one of the codes I have and I have a clogged PCV system.
It's not an exhaust valve. It's a variable valve timing solenoid on the exhaust camshaft. Do not replace it before clearing all of the OBD codes and see if it resurfaces.
I also feel you have a vacuum leak that may have been a result of something you may have done (or not done) when you replaced the PCV assembly.
Thanks for the great video and tip. Tried it on my D4 that’s getting thru oil and rattling, the glove inflated like a zeppelin straight away 😁
Sound like time to service PCV system.
Booked in for next weds at local Volvo agent 👍
@@bitsbobs5509 does it helped after service?if yes what they changed? Thanks
Hi guys I have a question about the PCV on a 2006 Volvo S60 R. When I do the glove test it sucks in at idle but then blows out when I press the gas. Is it supposed to blow out when adding boost? It's causing my return line o-ring to fail even after replacing the line, o-ring, and gasket. Also recently serviced the PCV. Help!
Hi, did you find out if that was normal? Or if not, what was causing it? Thank you
thank you for sharing this
My pleasure
I did this mistake and destroyed my 2012 Volvo s60
This is the only car in family so your idea destroyed my happiness 😭😭😭
This PCV system is such a dumb design. It’s really just a sub-par AOS. If your building the car convert to a real AOS if just a casual driver get a catch can and check it twice an oil change
I am driving skoda 1.6 diesel.
I am getting low oil pressure sign and smoke coming from oil cap with engine knocking. Pressure sensor are changed and oil pump as well but the problem is still the same. Any suggestions
I tested this in 2016 VOLVO XC90 and it is same effect ( vacuum )
Great, keep it like that! Thanks for your feedback AutoKanada.
Bzw, just checked your channel you have cool content! Cheers!
i literally dont understand my volvo. I replaced the pcv system 2 times one time with a non original pcv box, and recently with a original volvo part. It still hast postive crankcase preasure? The only thing i didnt replace was the big pipe going across the block. Also what was weird was when i removed the pcv box watery oil came out and left a mess. From all videos ive seen the bottom ports were always clogged up with coal like substance? Would be nice if someone could help me thanks.
I just replaced PCV diaphragm after my 2008 xc90 V6 was whistling. I tried glove test and Fingers on glove fill up with air. No suction. What now?
Hi Elfrain, sounds like you just replaced only replaced oil trap box without complete PCV Breather System replacement - tiny passages and pipes could be still be plugged up. Check this video from FCP Euro RUclips Channel, it should help you out (Volvo S60 PCV Breather System Replacement - Prevent Smog! (C70, S60, S80, V70, XC70, XC90))

Thanks for watching and subscribing. Let me know if you have any questions. Cheers!
In my 08 xc90 3.2 non turbo when I do this test the gloves doesnt suck in nor inflate. Theres no vacuum nor pressure. Is this normal?
Little bit a vacuum is okay not enough to suck glove in. At least engine doesn't have too much crank pressure.
There's a lot of clicking and clipping in the audio, maybe sound levels recorded too high
Thanks for letting me know. I don't like that idea anymore to add loud sound tracks.
I have my s40 it had that whistle and I took out the pipe coming from the top going down and the whistle stoped is there any problem with that.
About to try this on my 1990 745 turbo
I've got an 08 s60 2.5t awd. And I used a plastic bag, it was only very lightly sucked not nearly as much as in video, do i need PCV service?
Hi Mike. I won't worry about it right now but if PCV system hasn't been serviced since new I would check for suction every 5-10K km then if necessary service it.
I did this test with my 03 s60 non turbo and there was no negative or positive pressure at all. I tried using a glove and Saran wrap. Neither got sucked in, but didn't inflate either. Any idea what this means?
Hi Derek,
Seems like your Volvo does not have problems with crankshaft ventilation. Pull deep stick out, if you do not see any pressure means your crankshaft ventilated and engine has life left. Cheers!
@@PistonShack Thank you! The car just rolled over 200k miles and I am doing any maintenance I can to ensure another 100k out of it!
Hello, I need answer to the question what will happen if I cut the hose coming from the head, close the part going to the separator and vent the part coming from the head to the atmosphere by extending it and putting filter at the end of it?
I'm about to do it and I can't find any information on someone else who's done it. The reason is that the mechanics in my area do not acknowledge that kind of maintenance. They tried to rip me off with engine rebuild. I don't feel comfortable trying to replace the pcv system myself due to lack of experience and fear of mistake.
Hi Peter! Good point. What I will do if my crank pressure gets too high and no time to service it right away. I would just pull oil dipstick out a bit of the tube to let crank pressure vent out. It will take care of crank case pressure temporarily. As old school farm fix on old trucks and tractors just run crank case tube out but on Volvo it will be complicated. I will make a video later how to service Volvo PCV system.
@@PistonShack well the dipstick trick works but every time I drive when raining white gunk appears on the dipstick.
My question is is it safe to bypass the system the way I described earlier, at least until I gather the courage to service it myself? Also will it be reliable as a permanent solution because I did some research and pcv replacement kit is genuine pain to find in my country.
Are you ment to to this with the engine hot?
Hey Jamie. Hot or Cold.
So I just bought an 07 s60 t5. 135k miles. Tried this and the glove inflated but barely. How much time do I got ? I change oil every 3k sometimes 2k
Hey Kalen! On Volvo Positive Crankshaft Ventilation (PCV) system should be serviced every 50-60K km. Does it suck glove @2000-3000 rpm? I would do check every 2000 km or so.
I am using 5w30 Mobil1 Full Synthetic, doing oil change every 10000 km.
We have a similar engine setup. It seems you also do not have a fuel pressure sensor located at the end of the right side of the fuel rail. Can i ask you where yours is located? I am having trouble finding where mine is. Thank you!
Volvo v90 2017 same problem . 😢 I have replaced Gasket cover seal.
Most likely PCV system needs service.
@@PistonShackWhere is? Replaced the gasket and same problem.
System... Oh
I did the glove test, when you start the engine it does vacuum and suck the glove in, however when you hit the gas it fills the glove with air.... you think its dtill the PCV issue?
Hello Jasmine,
What vehicle do you have? It depends from vehicle to vehicle.
2004 xc90 2.9
my 2.4T does the same, or not inflates but the vacuum gets evened out to what id say atmospheric, but i am almost certain that my pcv drain is clogged, but the rest of the system working, cause it sucks in oil to the compressor housing
What would cause this to fail prematurely? I'm at 240k KMS and mine works great. I assume irregular oil changes?
Hi Tyler,
Overtime crankshaft pressure oil deposits build up, then the PCV system get clogged up. Poor quality oils and failure to do regular oil change speed up the process.
Cheers)
@@PistonShack in short its near impossible to avoid, its a matter of how often it needs to be serviced, do your checks and oilchanges and id say a typical white-block PCV should last atleast 25k metric miles
@@PistonShack Do you know anything about the Volvo engines in the 08 Land Rover LR2 SE??? Weird noise in the front passenger side vibration rattle ticking weird start but once warms up sounds fine??? But keeps a bussing sound and or tick, unless giving it gas, then it sounds perfect
What does it mean if it doesn't blow up or suck in? Vacuum lines are bad possily????
It means crank shaft pressure build up and gases cannot enter intake manifold to reburn. On Volvo oil trap canister and lines probably got clog up.
Umm.. Maybe don't put a glove over it incase it sucks it into the cam cover. Just place your hand over it lightly to feel the air flow. Too much vacuum is also bad
Hi Ben, you also just can place piece of paper or your hand. I have never seen Volvo engine with too much PCV vacuum. What kind Volvo do you drive? Thanks for watching.
Hi I replaced the PCV system in my 98 non turbo V70 yesterday, no more smoke from dipstick but oil spits from the filler cap, why is this? BTW my car does not have a flame trap. TIA
H, Tom. That's common problem on B5244 engines Volvo engines. Replace oil filler cap rubber o-ring and check the PCV pipe connection to the oil filler neck. I had the same problem before.
Thanks for watching and interest to my video.
Sorry for the late respond. I check a comments almost everyday but did see yours on the list. Just got it today.
Cheers)
When you refer to "regular service of the PCV system", what is it that is done? is it a cleaning, or is it a replacement of hoses/trap?
I do it every 50K kilometres.
@@PistonShack Thank you very much for answering, but what is it specifically that is done? What does "regular service of the PCV system" mean exactly? Is there less intense/expensive service actions that can be performed to prevent an entire replacement?
At what mileage on average do you begin to have problems with PCV system , I'm considering buying a S60R with 60k miles .
Thanks from the UK.
Hey Ellis. Well, Volvo service intervals for PCV system is 50-60K but based on my experience it goes up to 80-90K if you run good oil and change it regularly.
Volvo S60R edition is sweet, fun generally saying great car to own. Just check make sure car wasn't raced hard before by previous owner(s). I
s it manual transmission?
My Volvo has 335K right now.
Greetings from Canada. Thanks for watching!
@@PistonShack Hi its a manual in incredible condition cosmetically , I know the owner , he is talented restorer / mechanic , he has serviced it correctly using all the correct fluids , he has just serviced the haldex system , but I have many more questions for him b4 I buy , its a complex vehicle and don't want to buy it at a time when things are beginning to fail , pcv etc so I need to gather as much advice as possible b4 I buy , thank you for your advice and response 😁👍
What is that tube next to the oil lid....my volvo engine tube is cracked... the one next to the oil lid
If I'm not mistaken, that tube lead air from turbo to intercooler
hello thanks for the video. My English is not very good, I'm sorry, I'll ask a question, should the engine be warm or cold during this test?
Cold or warm, doesn't matter.
Thx bro
is this problem really affect the oil consumption.I mean 1 liters per 3000 kms?
I will contribute in general engine oil consumption for sure. Sound 1 L per 3000 km is way to much. Probably, valve stem seals worn out or oil piton rings as well.
Sorry if I may ask mine was making a whistle and I took out the pipe going to that air box and the whistle stop is the any problem with that cause it's driving nice
Bad diaphragm in pcv cannister
Wow
Just got 2001 Volvo C70 today I noticed smoke comming out of the hood but the temperature was reading normal but it’s the minor oil leak.
Hi Jacob! Probably oil was sipping down and burned on hot exhaust. Let me know if you have any questions. Cheers!
PistonShack got question so I took it to the mechanic today because the check engine light came on they said I need to change the timing belt soon or it could. Be bad do you know estimate price for it
Tnx Tnx Tnx. Genius idea. My question; why you mention your car brand (volvo)? You means to say this method of checking is not universal?
Yeah, you right you can apply the same test to most of the gasoline engines. I mentioned Volvo because they known for problems with PCV system if you don't service them regularly. Tnx for watching!
@@PistonShack - I have a Mitsubishi Lancer 1.6 invite 98 hk (benzin) 2006. I test the PCV as you guided, it took just 2 seconds and the gloves was almost sucked totally in.
Is it normal?
Yeah, that's how it should be. Your engine has healthy Positive Crankshaft ventilation. The engine should create a vacuum in the intake. Thanks for watching and sorry for the late respond. I missed your comment. Cheers.
I was waiting for the glove to be sucked into the engine
Not this time Jackson!
What is the vacuum is too strong and sucks the glove inside the engine!? Which if that happens it's you're kind of Sol
Nope, It will not happen. Well, plus Volvo has a metal screen at the oil filler neck. Thanks for watching!
There is a large grille at the oil filler opening so very unlikely the glove could get sucked in. Put a zip tie around the glove to hold it to the opening for further insurance if you want.
Can I try this on a Toyota Passo 2008? there's white smoke coming out of the dipstick and i've read that its normal and some other people say it has low compression. What do you think?
Hey Shika! You shouldn't have any smoke coming from engine oil dipstick tube. If you have some, it means your PCV system needs maintanamnce or engine itself is worn out.
@@PistonShack Thanks for answering, some mechanics say this is normal in some engines, The engine works perfectly fine and it doesn't have excessive consumption, should I go and to a compression test first, just to make sure?
I will do dry and wet compression test to verify engine condition.
or if you have bi-directional scanner with special functions you can do relative compression and power balance tests as well.
Are the result not the same between a 6 cylinder and a 4-cylinder engine ??
Hi Paul! There's no difference how many cylinders engine has. PCV system is the same.
Not sure if you still respond. I'm actually looking into a 2004 Volvo XC70 AWD, when you start it. It will blow out a ton of white smoke before settling. Will give this test a try. Will appreciate if you have any knowledge to assist.
Hi Coogi, Is your vehicle gas or diesel? Does it blow from oil filler neck?
@@PistonShack it's the gas inline 5.
You just put your hand over it and feel for vacuum you don’t need a glove and it might be a good idea to people who have no real idea what there doing to keep hold of the glove. Do the engine the world good if it gets pulled in.
On Volvo motors like this there is a grate right below the oil filler inlet. Makes it almost impossible for the glove to get sucked into the crankcase.
i just buyed a v70r 2004 and i wonder if it have be done,if the pcv system work fine, you just try on idle or need rev it a bit, at idle it suck in, but if i rev it a bit it seem wanna flake,i was alone for test it,i will retry with someone soon,ty
Greetings, if engine vacuum sucking while idling I won't worry about it. If glove pumped up right away then you have an issue with PCV. Cheers!
@@PistonShack thx for your answer, i feel better now ^^ yes the glove is suck in at idle,i will do it anyway eventuatly since i dont knwo when the last owner did and since is a volvo it will need be done soon or late,but atleast i know now isnt my idle problem atm
@@jeanfrancois777 I like Volvo cars. I drive my Volvo everyday. Volvo recommended to replace oil trap box and tubes every 60K.

I did this to my vovlo V70 turbo and 5 fingers came up. What to do now ?tnx
Hi AN,
Well, PCV system on your Volvo needs some maintenance.
Replace oil trap can, pcv hoses and clamps.
Do not wait until seals will start leaking oil out.
@inc.opt.63 not doing it will cost 1500+ ;)
Pull the dipstick out and put your finger over the hole....if it sucks your finger in slightly thats good...if it blows out thats bad. Way easier and you dont need a glove. I do this test every time i check the oil level as a rule and have a spare pcv membrane and cap kicking around for the day I will eventually need it. (2015 v60 t6 rdesign)
Hei feind. I have s80 2.4 D5 diseal it hasnt pcv valve, how to deal with it ?? I want to clean and open it becuse it not suck the air , i make oppesite
Hello! D5 Volvo Diesel Engines do not have the same PCV system as gasoline motors. D5 like most of diesels have an oil separator it might be clogged check it first. Also look for any Vacuum Leaks. Let me know.
Is this oil separator same the oil filter place or where is located?? And if its the same oil filter did i need to drain oil first then take out that filter place ?? To see the separator. For leak in pipes im sure there is no. But u can say the rear engine mount and maby font one also they leak??
No, oil filter is oil filter. I'm not sure where exactly oil separator located on D5. Follow engine ventilation pipes to locate the separator. We don't have Volvo Diesels in Canada. No you do not need to drain engine oil to service the separator. To find the leak wash your engine you that will help. Mounts don't leak - seals could be the problems. I hope that will help. Thanks.
Does this test work for diesel engines also?
Hi, John. I'm not sure. We don't have any diesel Volvo over here. Try it and let me know. Cheers!
Volvo Diesels, D4 and D5, don't have a PCV system .. they have an "oil separator" at the right side of the oil filter in connection with the crank case ventilation, were separated engine oil can flow back to the crank case. It's possible to take apart and clean but cleaning cases has shown that even after 200.000 km it's not even dirty. It is more important to keep a keen eye on the vacuum hoses in the engine bay .. fx. can a faulty engine mount (vacuum system) make some very funny noises from the oil filler .. like an old fishing boat. And the the EGR valve too to be kept clean.
Is there a danger of the gloved being sucked right in ?
Hi Peret! No, there's screen at the oil filler neck.
@@PistonShack Thank you I'll borrow a glove laterr and check my v70😁
Got a Saab that inflates the glove, pcv is working properly, I'm out of ideas...
How do you know that pcv works properly. Normally you should have vacuum.
@@PistonShack it's been updated and the check valve works. How else can I check it?
damm i whanted change my D5 to T5 but looks my truck is less expensive to drive
Hi Argis, sometimes total cost of driving truck could be less then some cars. Cheers!
Can i remove smoke out or not?
What you mean "remove smoke"? Thanks.
Mine is blowing veeery little. What should. I do?
Well, if I remember correctly: Volvo recommends to service PCV system on P2 chassis cars every 50K. Might be the time to service it.
How much should the glove inflate to if the system is blocked?
If PCV system operates properly glove should started sucking in, not inflating. Less pressure is better.
@@PistonShack I’ve done it and the glove definitely inflates. Looks like I’ve got a blocked system. Would you recommend cleaning it? Or replace? Thanks
