Replacing PCV Oil Trap on Volvo six cylinder engines 3.2 or T6 including Freelander 2 

Thanks for talking Russian (slowly) in the background. It helps keep that language alive for me.

Thanks for your videos - I have followed several of them to fix my 2011 S60 T6 AWD. My problem manifested itself as a P0171 code with the fuel trims at idle as high as +50 for both the ST and LT trims. I did observe the vacuum in the crankcase as shown in the video. I did not have the squealing and other issues described. My replacement from RockAuto still had a problem, which I diagnosed by using a DIY smoke machine. I finally bought the Dorman 917-147 PCV Valve Diaphragm from Autozone based on @OhWell advice below and fixed my problem. Also, per @a kamstra , I started the car and let the vacuum suck down the diaphragm into place and hold it while I put on the cap - it works very well.

Thank you for creating an amazing catalog of repair videos for these cars. I’ve used them for my repairs/maintenance more than once! 😊

I’ve changed this part one my 2007 XC90, it wasn’t creating the vacuum such as this, but, my oil consumption increased significantly. Which I found can also be a symptom. After replacement the oil consumption returned to normal. I always enjoy your videos. I’ve learned a lot and actually made a couple of repairs after watching your video!!!

Hello, thank you for your informative videos. I just replaced the PCV valve on my 2010 XC60 Volvo. For those who are replacing the valve for the first time, note should be made that the new valve needs to be oriented in a specific way. I haven't checked, but in all likelihood, the rectangular perforations fit only one way, but I just guided myself by the Volvo lettering on the original. The semi delta depression on the valve cap should point towards the firewall at about 11 o'clock.

Great video, For anyone following the swapping the pcv method (not the whole oil trap assembly), a trick to help installation is to push the membrane into the cap as far as you can and put a piece of electrical tape of the vent hole to hold the membrane in place and keep it from falling out during installation. Once installed remove the tape.

As per usual, clear, consise and very informative videos on Volvos. Great work!!

You have top tier videos! I have saved myself hours of frustration by watching your videos! Thank you for sharing. You make servicing Volvos affordable for the average person.

Hello VolvoSweden, I used to follow your SX4 videos. My 08 SX4 finally gave up after compression loss in one cylinder. It was a fun car to work on until that point. I have now just bought a 2011 Volvo C30 T5, similar interior space to the SX4 but, of course, a totally different driving experience and I'm still struggling not to fall onto the pavement when I get out - it'll help to keep me agile. I've always enjoyed your helpful videos and there'll be similarities to help me maintain my C30. Thank you. 🙂

Great video, thanks. RU-vid really sucks now that it has more ads than commercial TV so all I use it for are these types of videos. I wish there was another way to watch them because they are so helpful.

Very helpful video! I ordered an aftermarket cap only on Amazon and replaced in less than 10 minutes! Resolved the small squealing that has been intermittent. Original had small slit of about 1”. Replacement of original at 213k miles on 2010 S80 3.2.

Great video again Yuri. Many thanks for showing us the proper way.

Pro tip for all just replacing the cap. Put the spring and rubber part down first, then put the outer cap down on top of it (making sure you are centered and clearing). No reason to try to put down the full assembly as shown in the video.

Get the cap really warm or almost hot by using a hairdryer on high or a heat gun on low and use a pry tool to simply pry it straight up without touching the tabs. By softening the plastic, it should pop right off. Also spray the locking tabs with silicone spray.

2 videos in 1 week, keep up with the great work!

I dont have this engine but its Always fun and interesting to see your videos! Thanks from sweden

Thank you! Your videos are always excellent!

I love your videos! Thanks a million!

Great video thanks. My 2008 Volvo XC90 150k kms has increased vacuum pull from oil filler cap / dip stick. A lot of videos say that positive pressure i.e. the glove test is a sign of a bad PCV which confused me. I'll go with your diagnosis! My car also makes a funny mooing sound from the diaphragm every few seconds rather than the banshee scream plus has increased oil consumotion so hopefully this helps. I have ordered the new PCV so look forward to having a happier Volvo 😊

Alternatively you could replace the valve cover assembly gasket - Volvo PN 30757223 or FCP Euro PN 30757223 (i believe, best to call your dealer and confirm) - as this is the wear part of the assembly. $11 vs $280. Also, lol at "this is a volvo part from sweden" - *says FoMoCO on the front* I'm glad the engine cover hides those FoMoCos. Thanks for the vids! I've just ordered a membrane cap!

Great video again👍

This failed while I was on an out of town trip. I had the loud squealing sound. I made it to a Volvo dealer on a Friday afternoon. Volvo recommends this service at 100 thousand miles, I did not know this and I had regular service and it was not done. A five hundred dollar repair. Volvo 2008V70, 140,000 miles. I have always used the Castro Oil that Volvo recommended. I have been using Mobil full synthetic every 7500 miles for a long time.

Very useful, thanks.

I just did my 2010 xc60. I changed the whole assembly myself that was 377$ plus tax 🇨🇦. My car is pushing 250k kilometres, still runs great. I thought that the one I replaced was the original but after seeing how to check the date stamp from your video, I discovered that it wasn’t the original. Whoever did the install, I found some of the bolts came off by hand, about a third we’re just sitting in the holes and the rest were reasonably in there. I think next time, I’m going to just replace the membrane. The vehicle will be old enough and the thought of spending that kind of coin again, doesn’t appeal to me. Good job on the video guys! 😎👍 If you can leave a link where to purchase the membrane. I assume you were able to acquire a new cap with that as well.

Is there less or NO oil filler neck vacuum following successful repair? No whistle from the escape hole, but replaced the membrane which was torn. There is less vacuum on the oil filler neck, but there is still some. Engine sounds different when oil filler cap is removed vs on. Wondering if there is more wrong within the PCV cover assembly (blocked port?) 107k mile T6.

This is a great video, thank you. Saves me a trip to the dealership. Do you have an O2 Sensor replacement (searched but didn't see it), or is that even something that can be done in the garage? Trying to remedy a P0420 error while the CEL is on. Thanks again.

Thank you ever so much, I will change mine out be fore our trip. You both have been a blessing. But I have 1 request, I have downloaded d5td volvo dice and I can't get it to work on my windows 10 laptop. I can't figure out why my parking sensor wok so intermittently. I have 2010 xc70 3.2. I love this car. It isn't the fastest but I love shifting it and playing on the beach sand with it. 201,300 miles and strong as an ox. Always do the service or maintenance to her. Thanks from Florida.

I replaced just the membrane, fixed the problem. Of course I misdiagnosed it and replaced serpentine belt, tensioner, alternator pulley and finally removed the alternator to test if it was the sqeeling thing. RU-vid decided to show me this video AFTER I fixed it 😂

Thank you for video 🙏♥️♥️

hey, is the pcv cap (only the small part) the same on the 3.2 and the 3.0? i have a s60 t6 2011 with the same problem.

Great Video, I just bought an 11 XC60 with the 3.2 non turbo. It has this issue but is also low power and does not seem to be shifting properly. I am guessing this issue is is not the only issue? What do you think?

Can you buy the membrane and cap together? And where did you buy the part.

Se aprende gracias por compartir sus conocimientos. Podria crear uno para cambio de radiador xc60 2010

Diaphragm only replaced and found out it was torn on 1 inch on the side. I put the old spring down around the hole first and the remaining parts right on top of it using a small hammer. I had to break 3 tabs to remove the top. Yes, it is 9 times cheaper than the whole unit and guaranteed for life at FCP Euro!

If you install the new diaphragm with the engine on, it sucks the membrane into place and you don't pinch anything. I was fortunate enough to have received 2 extra on a parts order... Which I needed because using the method shown here I did pinch the diaphragm sealing seat on the first replacement.

From light bulbs to pcv breather, volvo after 2010 are so much easier to work on... Let me go cry in the corner (S60 2006) :')

Hey, where can i get the valve and the small cover? Can’t Seem to find it anywhere

I noticed the diaphragm is a Land Rover part number. Is this the same part for the 2.2 diesel engine 2007-2010 Freelander 2?

Is a lean burn condition something that can be caused by this?

Hello, i replaced the whole unit. Before there was no vacuum pull on the cap but know a little. And the pcv valve makes funny noises and blows air… is this a bad valve?

Is it bad to drive with vacuum for about 2000km more? But I don't know since when it is clogged... Thanks!

Do you have a video of open door and over head dome light on when actually the door is shut repair video. I’m having that issue with my 08 S80 T6. Thank you. Gary in Texas

добрый вечер, братан You nailed it on the job Yuri, hats off !! Without exaggerating you were one of the reasons i wanted to go P2 with my dream SUV and got a 2013 XC90 R-DESIGN 3.2. ive been always a 5cyl lad but i did enjoy a 1999 S90 2.9 NA . I never mess around with the pcv on these ! Stupid question if i may Yuri ? Could you add a catch can within the diagram ? It would help the pcv breathe better and backs it on holding most of sludge. Done it on all p80s i owned so thats why im referring to you on this one !! Keep it up with the great work sir 🫡🫡🫡🫡

Very important to replace the Thermostat and the housing too.

I'm a fairly experienced mechanic though my career no longer is doing it for a living. I'm getting ready to change the assembly as you did on the XC70, on my wife's 2010 non-turbo XC70. My main concern is what you used to remove the 5 T-30 on the back side. I'm planning on a 1/4" ratchet with short extension to T-30 either over the top, or from the sides, reaching behind. Is this how you did it, or is there a better way? Thankfully I don't have gorilla hands lol...

I have xc90 2011 , engine light on , when i erase the fault by the scanner the fault will comeback after driving almost 100km “p0420” , normally while engine running on idle no any sound come from pcv cap , i tried to check as you did in your video by loosing the oil filling cup i heard a noise coming from the pcv diaphragm cup when i tight the oil filling cup the noise is gone , is it mean that the diaphragm is damaged or that normal cause i loose the oil filling cup? Shall i go for the diaphragm? Thanks

I did this job last year. The oil trap was filled up with sludges. It worth opening up whole trap cover and cleaning up one hole in the middle and two openings on the side. Yuri normally clean up all parts. This time I notice he did not clean up the oil trap before putting the cover back on.

Did you get a check engine light? If it did what were the codes?

Nice, I did my wife’s today. 2014 S60 T6. 120,000 mi

I've got this issue at the moment, the replacement valve which I bought on ebay doesn't seal and the car is still drawing air via the dipstick/oil filler, any suggestions, I'm worried that if I buy another cheap valve it will have the same problem, any sources of reliable valves?

What if you have oil on the Spark Plug cylinder ..

2:32 that squeaky sound, what is it? where does this sound come from? i have same sound problem... and dont know what should i replace

so should we replace the whole PCV oil trap valve cover, or just the diaphragm? I was going to just replaced the diaphragm but noticed at the end you said should replaced the whole unit.

The diaphragm went out on my XC70 and the thing was SCREAMING as it went down the road lol. Never heard anything like it.

Dorman cap wouldn't lock into place without filing a little material off the bottom edge of the slots like @michaelb8957 mentions elsewhere in the comments. Even so, it still took a lot of force (I had to tap more than lightly with a hammer and rag to protect the cap) to make a secure fit-maybe I should have filed some more. Seat the rear tabs first, then work your way around the three on the front.

I've got a S60 T6 from 2015/2016 with 75000 km, do you think it's time to change? No indications yet of a bad pcv system

What a white ‘dust’ on both engines! My Volvo 2009, 255000 km does not have that, is it the cold, the salt used on the roads?

Quick question....I heard air from pcv and squeaking. Changed pcv diaphragm but still getting misfire in #2 cylinder. Could I need to replace whole assembly if still has vacuum from oil cap? I was hoping the cheaper fix would solve misfire issue but seems not. After pcv diaphragm change it ran fine for days before first misfire. Also never misfires when cold. Only when engine warms up! Please help!

What about the lower one next to the Oil Filter Housing?????

So I did just the diaphragm on mine, and my diaphragm was not damaged. I have 137k miles on my car, with the original PCV valve cover, so I am hoping this is preventable maintenance now. I will say the original pcv valve diaphragm is made by Volvo, or is at least stamped by them. I replaced it with a Doorman that has a lifetime warranty on it. Hoping I don’t have to use it.

I love you Guy's 😊❤ I change serpentine belt and pulley. And I keep having that noise ' ! Staff AutoZone guys Tell me the parts and checking and they said 100% . belt and tensioner with pulley . 😅 I keep having la issues " . The noise never go ' . And I keep having the check engine light on " 😣 Check engine light say my car will explode like a boom 💥 🤯 in any moment 😫 It is not surprised because very often the guys is staff. 🙆 Make me buy wrong parts " . 🤦 😂🤣 💯👍👌 I hope my car passed ' check smoke"🙆

I hate dealing with those charge pipe brackets soo much. Almost impossible not to break them

Did you see any engine codes when the valve failed?

Подскажите, плиз, на катком сайте в Канаде лучше заказать мембрану, заранее спасибо

3.2 and 3.0 have diftrent part number, and doesnt fit. Remeber that.

For me, only replacing the membrane did NOT fix the problem. I decided to fit the original Volvo complete assembly. After fitting it…no more problems!!! Cost me 170€ ex 21 % VAT at my dealer in Holland. For the T6 engine.

Although I appreciate these helpfull video's, this one I wish I didn't watch. I took his advise and decided to change the pvc diaphragm so I bought an aftermarket kit. My S80 3.2 has 120k mi and runs perfect. In order to remove the cap you must break the old one as shown in the video. I was able to remove the original without a problem however the replacement made by Dorman did not fit despite being told it will buy a few different websites. I ordered mine from Amazon for $28. The cover cap would not go down far enough to snap in place, so since I couldn't put the old one back on I had to improvise by filing down the open slots so it would finally snap down and lock in place. I thought the problem was resolved but after starting the car the diaphram made a gasping sound that didn't go away after a short drive. So I had to gently remove the cap and put the original diaphragm back in and now its fine. By the way the original was in perfect condition despite the high mileage. So I wasted time and money for nothing. I also found out that you cannot buy the cap and diaphragm from Volvo you have to purchase the entire cover at $266 as seen in the video. So I really regret changing this based on this video trying to do preventive care, so my advise is if your Volvo was always serviced properly at the correct oil change intervals then leave it alone.

Your engine doesn’t sound very healthy

Why don't you heat up a small screwdriver flat and cut this section of the cap?
