Thank you so much for the video. The mechanic I called was going to charge me $500 to fix this. Miraculously, my wife found your video by searching, “Volvo squeals while idling” and stumbled on your video, I had Autozone run a diagnostic test and it showed up as PCV valve. Bought the part from a Volvo dealer for $200 and installed it in about 20 minutes. Thank you for saving me $300 and making me look like a hero to my wife.

[@HowtoAutomotive]

BJ Thomas. Glad you saved $300 and came the Hero that’s awesome. Thank you for watching!

[@joshelmo4691]

Hi Brian, same for me as well but mine is a 2010 XC60 T6 with the same problem. Part number is also the same. Only difference is the rear of the PCV is really hard to get to. The XC90 has a lot more working room to remove the Torx 30 at the back. I lost two of them down the back it replaced them with bolts instead of the Torx. Anyway it took me an hour as I did it only but it saved me $$$ and the part cost me $180(australian dollars as I’m from Sydney). Thanks again mate for the video.

[@jsphgruber]

I am really appreciative of you making this video. I was concerned the noise was a more serious bearing type of issue. Your videos are very well done and thank you very much.

You are the man! Thank you very very much! Straight to the point and excellent instructions. Worked like a charm man! That noise is very alarming when you have no idea where it’s coming from. I was expecting the car to give out on me any moment lol. Got the part from Napa for $150 and was done in 30 minutes. Simply brilliant. Thank you again!

[@dougkwartler5274]

Hey! Thanks for the video. I followed it and did the job! I did end up getting a much more affordable auto ratchet and an aftermarket pcv/old trap, but it all worked great. Thanks!

[@marcwoodward8056]

The torque for the bolts is 10 Nm or 7.4 ft-lb in case anyone needs to know. Since the housing has metal reinforcement at the bolt holes your rule of snug plus a quarter turn should be sufficient for all those who don't have or want to use a torque wrench. Thanks for the video!

[@pgreenx]

Do we need the $200 part in the affiliate link or just the valve/gasket?

[@marcwoodward8056]

@@pgreenx the valve is part of the housing that has the gasket attached. You can buy a valve replacement kit much cheaper to just replace the valve but that is more involved & may not last. You do not need the power ratchet in the link, just the replacement part. You can easily replace it with hand tools. I highly recommend magnetized torx bits for the rear screws since there's very little space & is easy to drop them.

[@pgreenx]

@@marcwoodward8056 thanks for the response. Going to try this next week after I diagnose my “AWD disabled” message. Think the handed pump is bad. Always something.

[@marcwoodward8056]

@@pgreenx FYI...I realized the work being done in this video on the XC90 which has allot of space between the housing and the firewall. I have a 2014 XC60 and the procedure is pretty much the same except that the XC60 has very little space to get at the back screws thus my recommendation of the magnetic torx bits which I did not have at the time so I used electrical tape to hold the screws onto my bit. If you have an XC90 like this one the job will be super easy!

[@matthewlopez1348]

Can a busted diaphragm on an oil trap cause no start? My 2009 S80 apparently had a malfunctioning oil trap and caused the engine power to drop while I was driving. After returning home I was going to drive the auto store to have them read the codes, however, my car sputtered and stopped. This happened after a few attempts and it has not left the driveway since. Prior to this I did have code P0171 and I was troubleshooting: Cleaning the throttle body (it was gunked up), cleaned the mass airflow sensor with a mass airflow cleaner. Just bought a new oil trap and I am running through my troubleshooting options before installing this part.

[@DrewDienno]

would the same basic process apply to a 2011 s80?

Is it possible to just replace the PCV Valve Diaphragm Cover Membrane?

[@user-de2zt2sh7s]

Thank you .

[@dwood1546]

I am getting the P0171 and P0174 the same day this noise started. The noise you have is the exact same thing I am hearing, but you didn't mention the code/check engine light at all. Do those codes match the noise I have and the problem you addressed? Thanks!

[@HowtoAutomotive]

Derek Wood this definitely could cause those codes. Which is basically an internal vacuum leak. That will make the vehicle run lean

[@dannybailes3948]

So I was wondering if you can change the value in the trap out without having to also buy the whole system? Like could you buy just the valve?

[@paulwooton4390]

You're all past this by now, no doubt, but there is another video of a guy cutting the cap in two and installing a new one. Myself, I'm just trying to pry the old cap off, probably going to ruin the cover and end up changing the whole thing, per this video.

[@hskujama]

I have a 2011 XC60 T6 and it has 1615xx miles so far. I got a p0171 code first about a year ago but I keep driving it without any issue. Acceleration is good and idle running is smooth. Gas mileage is also consistent. Couple months ago I got a P0193 code so I replaced the fuel pressure sensor today and code 0193 was gone. I don't hear the high pitch/whistling sound while the engine is running (park the car and open the hood) however, I did hear the hissing sound when I pulled the engine oil dipstick out and it was hard for me to open the oil cap. Do I have a bad PCV oil trap? Thanks in advance for you reply.

[@edijares1543]

Yes. It's time to replace it.

[@amazingmisha]

Great video....how do I know its my oil trap work normal...is that screaming only symptom...my 3.2 is over 333000km and the problems are starting, first alternator in one moment start screaming...then all lamp on table is flashing...ok tommorow mechanical is finished work, but Im worried because missfire 1 and 5 cylinder...hope its only spark or coil

[@HowtoAutomotive]

misha misha another symptom have a bad PCV oil trap would be oil consumption. Also if you tried to pull the cap off with the engine running it should be a light resistance but still come off. If the breather is bad it’ll be very hard to remove the oil cap.

[@amazingmisha]

@@HowtoAutomotive thanks a lot..this is so professional

[@JackZenert]

Why could you not just replace the round diaphragm rather than the whole houseing?

[@c_rock3512]

Can the diaphragm valve itself be replaced without having to replace the entire assembly? I bought the diaphragm by itself (it’s like a $20 part) but am having trouble getting the old one off.

[@pgreenx]

How did this go? Didn’t want to spend the $200

[@c_rock3512]

@@pgreenx I ended up just buying the valve for about 15 bucks. My girlfriends dad helped me out and we took out the assembly and just replaced the valve. Worked perfectly so far. You’re just going to want a torsion wrench and a magnet to keep the screws from falling on the engine. All you have to do is pry the valve off and pop the new one on but it’s not really possible unless you remove the assembly. Went well actually, cheap repair.

[@pgreenx]

@@c_rock3512 thanks. This afternoon I bought the Oem part from FCP for $130. So I didn’t feel so bad about the $200. Thanks. I have no help and noob mechanic so a plug and play part is best for me especially since my cover is leaking oil.

[@c_rock3512]

@@pgreenx if you’re leaking oil that’s probably for the best anyway. Good luck with the repair man. Definitely bring a strong magnet with you. If those screws fall in the engine that’s a huge problem. Magnet saved my ass.

[@JonasAnuzis]

It seems I have some vacuum when trying to lif off the oil cap. I am currently trying to diagnose what is causing rough idle (with detectable misfires) in T6 (3.0T). My mechanic suspects that it could be faulty oil trap (pcv). What is strange, what car stops registering "misfires" with oil cap off.

In the video you indicate that you do not know how tight the bolts should be. I looked it up in Vida. Vida indicates that the bolts must be tightened to 6 Nm.

[@pgreenx]

Are you sure about that. I heard 10nm

[@dwood1546]

I just took it to a mechanic who confirmed the diagnosis and the easy repair but they told me they have seen this before and to be very careful to watch for an oil leak somewhere down the road… May happen, may not happen but why might that be?

[@aaronbader2010]

If you drive with a bad pcv box, will it cause more damage to vehicle? I am about 40 miles from my mechanic.

[@HowtoAutomotive]

Aaron Bader So what happens when the valve goes bad is it builds up pressure in the inside of the crank case which could cause oil leaks. So it is risky driving it with the valve going bad.

[@WojtekCBRF]

I have s60t6 and p0171 check engine. IT may be pcv valve? What do you suggest to check?

[@HowtoAutomotive]

It’s a very common problem. One of the best way to test, for it is with a smoke machine.. another tale is when the engine is running. If you try to take the oil cap off, you’ll feel a lot of suction on the oil cap and that’s also an indicator that the PCV is going bad.

[@WojtekCBRF]

@@HowtoAutomotive i will check oil cap. I got check engine about week, can i drive "safely" another week until buy new Valve?

[@WojtekCBRF]

On running engine is suction on oil cap for a while. Then pcv Valve is foulty?

[@VoidCommander808]

How do I reset the check engine light after replacing the oil trap though?

[@HowtoAutomotive]

Do you have to plug in a scan tool or code reader And follow the prompts to clear the codes. If you don’t have one a lot of auto parts stores will do it for you.

[@hannahayden2484]

Hi, I’m looking to make this repair myself on Friday. The parts store didn’t have the cover in stock, just the valve - will that affect any of the new performance? I’ve also had to drive about 130 miles since the PCV fail noise started before I can get it repaired. Is there anything else I should look at because of that distance? Thank you so much for the straightforward video!

[@HowtoAutomotive]

The car may burn a little oil so double check your oil level. Also it may set the check engine light for a lien code P0171 you’ll have to clear that after you do the repairs. Good luck with the job.

[@zubairkhalid685]

Can I just replace the valve and not the whole thing?

Why not just replace the diaphragm

[@rayalarcon115]

It's $50 at AutoZone and comes with a cap, diaphragm, and spring. If the oil trap isn't leaking you won't need the $200 full setup. It took me all of 5 minutes to change it and that is because I didn't look closely on which way the diaphragm faces. Plastic part goes towards the engine with the spring in the middle. All rubber side goes toward the cap.
