I did this a couple of years back with the help of this video. Just stumbled on this video again today and realized I never said thank you. So, THANK YOU! Would never had done it without this.
Excellent video, commentary, step by step.Well done young man! I just did this on our 96' Volvo 850 turbo sedan with the help of your video. My fiancee's volvo she purchased new. 278,977 miles and still going strong. Greatly appreciate your video!
For those wondering, the process is nearly identical for a '98 S70 T5. Only a couple differences, with the way the fuel rail is connected to the intake manifold, and the vacuum tree is slightly different. Take the fan off to make your life way easier. The toughest part of the repair is getting the 2 bolts on the bottom of the manifold (at 3:45 in the video), and also the left-most manifold bolt is pretty tough to get to. Ben makes the dipstick and manifold bolts look really easy but that's because he knows exactly where the bolts are. Finding them in the first place is the hardest part, but putting those bolts back in place when you're done should be a lot easier.
Ben, Really appreciate your video! I spent almost one day to finish the PCV replacement, spark plug replacement, rotor and distributor replacement, all based on your videos yesterday. After I finished all these jobs, I started my car and expected the perfect running of the car. But unfortunately, the car cannot be started. The check engine light is on, the code is P0201, 202, 203, 204. After reviewing your video the last night, finally, I realized that no-starting may be caused by fuel system. This noon, after I checked the fuel injectors, I found that the fuel injectors are not wired ( I plugged the wires into them in, but in fact, they are not connected). So after plugging the wires into the fuel injector correctly, the car runs great! Thank you very much!
I successfully completed this repair last week, thanks to this video. Although, i cut up my hands pretty bad trying to get the bolts off the bottom of the manifold. When I put them back on, I used a couple ratchet extensions and approached them from the bottom of the car, as opposed to trying to reach under the manifold again. Running great now!
If I ever have to do this job again, I will use Genuine Volvo parts, the aftermarket kit I purchased works, but doesn't line up so well and I spent a ton of time fiddling with it. I would also suggest replacing knock sensors at this time, since you have to take the intake manifold off to do that when they go. The car in this video has the original knock sensors still, a great DIY video from FCP would be teaching people how to install the Volvo upgraded knock sensor kit. You have to splice the wires and all of that, a solid DIY video would be super helpful to others on that topic.
Great video! Thanks a million Ben and FCP. I it really helped when I tackled my PCV system last summer. I have only one suggestion: Don't bother trying to unbolt the fuel lines from the dark recesses of the engine. Moving the lines and fuel rail out of the way while still connected caused a huge headache for me, and I ended up bending the lines a little out of shape. Just empty the pressure from the fuel lines by using the schrader valve at the end of the fuel rail, and then disconnect the fuel rail from the fuel lines. You also won't have to worry about the injector popping out as much since it won't spill as much fuel.
Thanks for the video! I was reluctant to tackle disassembly of such a complex system until I'd seen it done step by step. Smoking dipstick is now fixed.
Thank you for sharing. I had a volvo and always loved them. My girlfriend is in the process of purchasing a XC90 -06 and she is scared because of the horrors of foreign car costs. I believe in Volvo and I told her as long as she talkes care of them they will last forever.
The best manual on the Internet. Fast and useful. Thanks a lot! I had to remove intake manifold because of vacuum leak in it. Caused misfire, unstable idling, stalling, very bad mpg and low performance. Now it is working perfectly. Thanks again for the video.
such an easy fix took me just under 3 hours including the new cam seal behind the distributor. you are my go to guys for all my Volvo needs. The fuel injector orings were fine,
I did this job last Summer on my 1994 850 Turbo and, after taking everything apart, I found that the previous owner had the PCV system replaced seemingly right before I bought the car. All the PCV stuff looked brand new(Genuine Volvo parts) so I decided to just reuse everything and return all the parts that I bought. Before I did the PCV job, there had been oil accumulating on the top of the cylinder head by the spark plugs, but I thought it was the oil cap o-ring. Fast forward to today and I noticed that there was even more oil on the top of the cylinder head. It turns out that the oil was seeping out from around the upper PCV hose port. I loosened the clamp and noticed a large crack in the end of the hose. So, now I have to do the whole job over again just to replace that top hose. I should have just replaced everything the last time. Grr.
What a brilliant video. I've just got the bits to do this job (and full service) on my '97 non-turbo V70 2.5 20v (UK spec). I'm happy to take bits apart and this gives me absolute confidence to do it now! Thank you :D And keep up the excellent videos, all makes owning these lovely cars even easier.
Just spent all day trying to get the two bottom center bolts out. Trying a wobble extension in the morning. If that doesn't work I am walking into the woods and never returning.
Hi Ben, car runs perfect again, took down the injector cables again and checked them with a multi meter, they were all ok, then I cleaned the contacts on each injector a bit, then lastly sprayed some contact spray on the cable side but not on the injector side, also tapped on each injector with a large screw driver - one time firmly on each one, tapped with the plastic handle side, then the car started perfectly and now runs better than ever! Thx for you gr8 video, helped me a lot especially with the fuel line trick, just put all to the left, I would say the job is quite time consuming for a first timer and I must say that the hardest part was to put back the two screws, one for the intake manifold underneath and the other one for the oil dipstick, hard to do when you have big hands like me, almost 6ft10 and 245 pounds guy...... My neighbour had to help me since I did not manage and almost got mad trying. I also could not putt the injectors out in the first place, they did not want to come out, I sprayed some penetration oil and then they came out easily. But again the video is great but you must be prepared to spend like 8 hours for a first timer, this is when you really take time to clean all and mark up each screw, bolt and connectors, I used different type of coloured tape to help me keep track.
The PCV system is usually a breather tube and a PCV valve. The tube connects the crankcase to a clean source of fresh air that flows into the engine after passing through some sort of screen to stop any flame fronts. Inside the engine air circulates clearing away combustion gases that exit through another screen to trap oil droplets before being drawn out through the PCV valve, and into the intake manifold. It’s essentially a way for gases to escape in a controlled manner from the crankcase.
Thx Ben! Your video helped a lot yesterday when I did this job on my Volvo V70 1997 170 bhp Petrol. I removed the thermostat hose to give me more room to reach the lower left bolt on the intake manifold, otherwise all went really well, hade to spray some penetration oil on top of each injector to be able to remove the injector block from the manifold.
Thanks for this. On the XC70, it was a difficult job, but I got through it successfully thanks to this video. (I wouldn't have tried it otherwise.) Your PCV kit was fantastic. Only suggestion I have would be to include standard screw-in hose clamps instead of the one-time use clamps. I found it easier to get the manifold back on using standard clamps, and without the right tool, the pinch clamps seem a bit risky. Keep up the great kits and videos!
Awesome video. Thank you very much Ben! I've been getting all my parts from FCP as I have restored three 98 Volvo s70's so far. Looking for a T5 with spoiler. The 98 s70 in my opinion is the last great car Volvo has built! All mechanical linkage. In regards to video I didn't mess with the throttle linkage or the idle control valve. It is safer to get it out of the way but just be careful where you place the manifold when removing. I also jacked up the front and removed the oil bracket from under car. The job took five hours, but that was having lunch and being extremely methodical. All and all piece of cake.
Thanks Ben and FCP for the video! I used this step by step procedure to fix the PCV system on my 1998 V70 T5. Instructions were great and easy to follow. charles
Thank you very much for the video! I have a V70-98 series that needed the system replaced, saved me some money doing this myself with the help of a friend and this video.
Great tutorial, very informative. I had to do this on a NA version, but the procedure is close enough to follow with success. I used a FCPeuro kit and everything fit perfectly. thanks
Awesome job on the video Ben! I would have done the job myself if this video was out a month earlier! Always next time. keep up the great work! This is a very valuable asset and makes me feel great about getting my parts from FCP
Hey Ben what a great detailed video, I will be replacing my split breather tube soon. I found the problem myself after spending over £250-00 on so called experts to cure a rough idle and excessive fuel consumption. Tom
Hey Ben, Thanks so much for this video as well as all the others. I just did this job this weekend on our '98 S70 T5 and the video was a HUGE help. Keep up the great work!!!
The EGR valve doesn't have to be removed however you'll have to remove the line to the valve. As far as testing the valve its best to remove it and apply vacuum to the diaphragm. At this time you can inspect for carbon blockage and clean as necessary. Hope that helps!
This is great- do you have a video showing a P2 xc70 PCV replacement? This video definitely makes me feel a bit more knowledgable and confident about performing this job on my own car soon! Thanks!
Thank you for this awesome guide! Will be doing this sometime this week and have been a bit nervous about it... until now. Really, great guide which will help many doing this themself!
The EGR Valve does not have to be removed as it bolts closer to the intake manifold not the exhaust manifold on this vehicle. You may have to loosen the EGR piping however. Hope that helps.
The first thing I would check would be the accessories I.E. A/C compressor ( which is right near the filter; see if the noise changes in pitch with the A/C on and off ) Alternator, PS pump, and Tensioner pulley. A whine is usually accessory bearing related. Hope that helps.
Thank you, Ben, for this great instructional video. I'm convinced mine needs to be replaced as I saw smoke coming out of the dipstick a few days ago. I've had smoke for a while come out of the engine oil cap, whenever removed. I have a 2004 xc70 turbo with 145,000 miles. I bought it used and have only just begun to do my own auto work June 2017, other than oil changes. My questions are: 1-What is the brand name and specs on that cool bending-handle ratchet you're using; 2-What is the name of those crimping hose clamps, and the pliers you used on them; 3-Are there any significant differences between the processes you detailed in this video and the processes for my xc70? I wrote down everything you said, step-by-step, and once I get it typed up, I'll add screen shots from your vid and post it here for other users, if that's ok by you. Thanks again.
Hello Bernie, Hope this answers your questions. - I'm not sure of the exact brand but its a flex head ratchet. GearWrench sells a nice set at a good price. - Oetiker Hose Clamp Pliers - Process is similar but may not be identical. The essential information can be used though.
Having done this job back in 2008 on my 95 850T, I wish you had this video up then, because from my own memory, I don't think I did my PCV valve job correctly. I was using the Brickboard.com's instructions. And I have to concur with the poster that added that this job is a PITA. It defines PITA nicely. And my dipstick tube has condensate in it yet again.
Hi FCP, I'm currently having trouble figuring out how to pass my emissions. First thanks for all your help w/ your videos. They're great. My NO (smog) test was the only portion of the video I failed. I have a 98 S70 Volvo. I understand there's no EGR valve. Didn't know what else I could look at to help. I checked for vacuum leaks at most places I could see w/ carb cleaner, but didn't get any change in engine idle. I bought some seafoam to insert in a vacuum line and the gas can to help. Any suggestions? Thanks, Kyle
Hi Adam, That bottom bracket can sometimes make things a bit difficult. My recommendation would be to loosen the manifold and bracket, while keeping the bracket loose, tighten the manifold and then the bracket after. This should ensure that manifold doesn't have anything in its way preventing it from sitting flush. I hope that helps - Jason
Hi FCP Euro, i just completed this replacement yesterday with a kit i recently bought from you for my 2000 C70. Today i turned the car on and warmed it up to test the pressure. Unfortunately, the car tested with pressure still. I used the glove test and also saw smoke coming out of the dipstick. Do you know why this could be?
The reason he didn’t answer is the video is very old. He isn’t checking for new questions about this most likely. Make sense to you? Lol. Give youtubers a break Brother. They don’t all make money off this. And work full time jobs and have a life. WOW.
I just turned my dipstick tube into a vent. That goes into a oil catch can . Works great! Fix cost ZERO! I got the car for free. And im not spending one red cent more than needed.
A quart a day is a lot of oil to be losing from the dipstick. But it's a small fairly easy seal to replace. It might be worth trying then seeing where you stand.
You know, a $5 PCV valve would have sufficed just fine. Derogatory comments aside, I'll be doing this on a non-turbo soon and I appreciate the step by step. I've been messing with Jap cars my whole life so this is all new to me.
You'll want to check for vacuum leaks and maybe clean the throttle. Also, disconnect your battery for about an hour to reset the adaptives. Hope that helps.
You could have a clogged oil drain passage to the block or a sliced/loose hose. Or it's possible you could have installed a faulty vacuum valve that could be faulty. Hope that helps.
Fuel rail also has a separate rubber seal that sits between the injector and the fuel rail seat. Maybe check it didn't fall out if the injector is separated from the rail. I lost one when I did this. They're about $10 each from a dealer!
Sigh....I used this video as a guide to do my PCV system and into my car (95' 850T wagon) as far as lifting the intake manifold then - wait a minute, what the hell is this carbuncle hanging off the bottom of the manifold? I discover that it's part of the EGR system!!! Hmm, interesting. No mention of that in the video. Wish I had more space to describe what a gigantic cluster the project turned into. Thanks FCP!
This is much more work than simply replacing a PCV valve like on an American car. How might one know that this task of replacing this PCV system is necessary? When the Engine light goes on? Rough idle? Does the oil separator box ever get filled? (Oh, but this video is very helpful, my Haynes manual doesn't even write about the 850 PCV system.) Thanks.
Hello John, some of the symptoms include: -Noise (whistling) - Noise due to high pressure in crankcase. This noise will stop if the oil filler cap is removed. -Poor Drivability, clogged crankcase ventilation can reduce the engine performance -Uneven Idling Caused by clogged crankcase ventilation -Oil leak from engine seals due to restricted crankcase ventilation -High oil consumption/noise from Turbo
You can tell if it is starting to clog by warming up the engine, then place a rubber glove over oil filler neck and place a rubber band around the neck to hold it in place. Start the engine, if the fingers on the glove indicate a vacuum your good. If the inflate the change ASAP.
Purchased the PCV service kit from FCP. You changed the dipstick oil tube O-ring wouldn't this also be the appropriate time to change the injector O-rings as well? I may just be over thinking things may be a nice addition to the kit though. I'll let you know how this goes as well as how long it takes. Great video.
Fcp euro seems to be the only place I can get certain parts for my car too.. eventually I’d like to do a diesel swap but again idk if I could even get that in the us
Can you do a video for replacing a timing belt and components for Volvo Xc90 t6, 2005. Or do you have a video already that the procedures would be essentially the same. Thanks and keep up the easy to follow videos.
You may have to remove the coolant line that goes through the timing cover. If you have that setup, my advice is to remove the hose from the coolant reservoir side and slide the timing cover around it.
It was so painful watching him bend the hell out of that fuel rail. You can easily remove it by taking off that one fitting and the small clamp. Lol very helpful video to say the least.
As a 850 T5 owner just want to say a very big thank you, you are two piece of God, man! I have one cuestion: what is the PCV box exactly? I mean what does it stand for and what does in contains? Is it electronic stuff or just a connection point to the housing?
hamaramadarat A PCV (positive crankcase ventilation) breather system is designed to regulate hazardous waste from your vehicle. As your engine runs, combustion gases escape from the combustion chamber, finding their way into the crankcase of your engine. This unused combustion gas, also referred to as “blow-by,” can be a major cause of smog. A PCV system prevents pollutants from escaping into the environment and vehicle manufacturers started fitting engines with a PCV valve to ensure that gas remains contained within your vehicle.
It's not a belt kind of sound and It's not the PS pump for sure. I haven't tried opening the oil filler cap to see if the sound disappears but I tried a latex glove on the fill hole and it inflates, smoke also comes from the dipstick tube. I'm willing to bet it's the PCV making pressure on cold days and the sound is from forced air bubbles or excessive pressure buildup somewhere near the oil filter :)
I've been ordering parts and using your videos for awhile now. Thank you for all your help! One question, this PCV replacement process is basically the same for a 1998 S70 base model, correct?
Thank you for the support, Alexander! We're happy to help! Yes, you are correct, the PCV replacement process is basically the same for your 98 S70. There are some differences in the vacuum lines and air hoses on the Turbo vs NA model but otherwise, it is the same process!
my car is a volvo 98 v70 5t. didnt see nothing change. well i need to change that part too. omg i need a man help. theres things i can do , but theres other part little hard to remove .i did like the way you it. easy and clean. nice job !!
Nicely done, will revisit this video when i overhaul mine. I'll have to replace the timing belt/water pump, radiator and I think by removing the radiator/shroud first, will give me tons of room to work around the manifold. Now, has anyone ever replaced just the pesky vacuum elbow that sits right in between the power steering pump and intake manifold? The one with one port larger then the other that fails and triggers a P0172 code! I'm wondering besides long needle nose pliers, what other methods have you used?
Thanks Ben, my dad just gave me his old volvo 850. Really nice car and has all the features amodern car has. Trying to get my head round the my new car. What is a PCV breather system and what does it do?
It would be nice to know what tools you used so we can own the correct tools. I struggled removing the two 12mm bolts under manifold from below. You made it look easy doing it from above. What were the tools? I also struggled with the first manifold bolt on the passenger side (US) .
This is a great video. It is thoroughly detailed. Do you have one performing the same service on a 1995 Volvo 960? I have the searching idling problem and someone said it was the intake gasket.
Great video FCP. Will be attempting this shortly. Quick question for you guys. Does a 95' 20 valve non-turbo 850 have an egr valve? If so, does it have to be removed to get the manifold off? Thanks for your time.
Van Troy Osorio It may be, but the first thing I would check for would be for vacuum leaks. A vacuum leak is more likely to throw off the fuel trim. Hope that helps. (Sorry for the strange reply, it wouldn't let me respond to your actual comment)
Brian Quero Any oil will do in any gearbox before M90 as long as it is for trans, im sorry to tell you but if you cant fix a B230 you are really bad...
Hi FCP Euro, i just replaced the pcv system on my 2000 C70 with a kit i bought on your website and i did the glove test on it for pressure and the glove blew up. I also checked the dipstick and smoke was coming out of there. I took it for a 13 mile ride and retested it and same thing. Any idea of what it could be?
great Video ! However I am trying to determine whether I need to undertake this procedure. I have done two tests, Firstly I removed the dipstick end with the car running and looked for smoke.... which there wasn't any. Then I put a glove over the oil cap to see if it inflated and it did. So i don't know what one to believe
josh grantham The Glove and dipstick tests are only used for a general indication of if you have positive pressure. To gauge an accurate reading he'll need a low caliber vacuum guage / Manometer.
Great video! A poster on one of the forums made mention of a banjo bolt somewhere, though from your video I only see you interacting with basic hoses and clamps. Is there in fact a banjo bolt somwhere in the system? Also, if i want to remove the fuel rail instead of bending it back, is it connected to the intake fuel line with a basic threaded connector and crush washer?
Great video! I have a 1983 Volvo 244 Turbo and I have no Idea how to get the intake manifold off to get at the PCV what with all the hoses and wires in the way. Any videos that could help me out? There's not a whole lot out there about it.
For me if it is clogged, I will drain engine oil first and not plug in the drain bolt. Then I will open the top vent hose on cam cover and spray alot of carb cleaner. Leave it over night to let the gum-gunk dissolve. I may spray carb cleaner or pour gasoline fill to the long vent line at the end that connect with PTC. To make the solution liquid fill along the tube, it need to connect extension tube that route to higher position which gravity will do the job of solution filling. After settle one more day, you can check if the clog problem is eliminated or not. If not, then it need to do disasemble the intake manifold for better inspection and replacement the clogged or damaged parts.
Love this video! Any advice for the same job on a 1995 960? I can't seem to get the intake manifold out. Does the EGR have to be disconnected somehow to remove the manifold, and if so, how do you get to it (considering it's under the manifold)?
Ben, Thank you for the excellent video. I have read that the use of a premium synthetic oil will prevent or deter this repair which I imagine costs over $500 at a dealer. Do you agree? Sam Julier
It will hinder the chances of oil sludge if changed regularly however if any oil is left in a vehicle too long the same results will surface. Moral of the story - change your oil frequently no matter which grade or blend your using.

You're welcome James!
We didn't leave anything out of the video, but of course some years will vary slightly. Glad you ended up getting everything replaced ok.

Dang man. You make it look like putting lego pieces together :):) For me it would be a one whole day job if I don't break anything. Job well done.
Before removing the fuelrail, you can always release the fuel pressure by pressing the little valve next to your throttlebody on the fuelrail.
You R correct,it is this same design as tire VENT>

My neighbour had to help me since I did not manage and almost got mad trying.
I also could not putt the injectors out in the first place, they did not want to come out, I sprayed some penetration oil and then they came out easily.

You did this in less than half am hour like a puzzle. Very informative too bad I am not a mechanic but you make me systematically want to tackle this
I believe in you, Herbert! Just take your time with it and I'm sure you'll be able to get it done!
Thx Ben! Your video helped a lot yesterday when I did this job on my Volvo V70 1997 170 bhp Petrol. I removed the thermostat hose to give me more room to reach the lower left bolt on the intake manifold, otherwise all went really well, hade to spray some penetration oil on top of each injector to be able to remove the injector block from the manifold.
Thanks for this. On the XC70, it was a difficult job, but I got through it successfully thanks to this video. (I wouldn't have tried it otherwise.) Your PCV kit was fantastic. Only suggestion I have would be to include standard screw-in hose clamps instead of the one-time use clamps. I found it easier to get the manifold back on using standard clamps, and without the right tool, the pinch clamps seem a bit risky. Keep up the great kits and videos!
Awesome video. Thank you very much Ben! I've been getting all my parts from FCP as I have restored three 98 Volvo s70's so far. Looking for a T5 with spoiler. The 98 s70 in my opinion is the last great car Volvo has built! All mechanical linkage. In regards to video I didn't mess with the throttle linkage or the idle control valve. It is safer to get it out of the way but just be careful where you place the manifold when removing. I also jacked up the front and removed the oil bracket from under car. The job took five hours, but that was having lunch and being extremely methodical. All and all piece of cake.
Thanks Ben and FCP for the video! I used this step by step procedure to fix the PCV system on my 1998 V70 T5. Instructions were great and easy to follow.

Excellent video Ben, it takes the mystery out of replacing the PCV unit.
I don't have any volvo but enjoy to watch , you described it very clear. Thanks bro
Glad you liked it
Thank you very much for the video! I have a V70-98 series that needed the system replaced, saved me some money doing this myself with the help of a friend and this video.
Thanks Ekan, We're glad it worked out well for you!
Great tutorial, very informative. I had to do this on a NA version, but the procedure is close enough to follow with success. I used a FCPeuro kit and everything fit perfectly. thanks
wow this job is a backbreaker if you've never done it. I couldn't have done it without FCP, Thank you!
You're welcome!
Awesome job on the video Ben! I would have done the job myself if this video was out a month earlier! Always next time. keep up the great work! This is a very valuable asset and makes me feel great about getting my parts from FCP
Hey Ben
what a great detailed video, I will be replacing my split breather tube soon. I found the problem myself after spending over £250-00 on so called experts to cure a rough idle and excessive fuel consumption.
Tom
This young man is some mechanic wow he's awesome!
Best automotive instructional video I have ever seen. Thanks.
Hey Ben,
Thanks so much for this video as well as all the others. I just did this job this weekend on our '98 S70 T5 and the video was a HUGE help. Keep up the great work!!!
The EGR valve doesn't have to be removed however you'll have to remove the line to the valve. As far as testing the valve its best to remove it and apply vacuum to the diaphragm. At this time you can inspect for carbon blockage and clean as necessary. Hope that helps!
This is great- do you have a video showing a P2 xc70 PCV replacement? This video definitely makes me feel a bit more knowledgable and confident about performing this job on my own car soon! Thanks!
Thank you for this awesome guide! Will be doing this sometime this week and have been a bit nervous about it... until now. Really, great guide which will help many doing this themself!
The EGR Valve does not have to be removed as it bolts closer to the intake manifold not the exhaust manifold on this vehicle. You may have to loosen the EGR piping however. Hope that helps.
Dude knows his work.
The first thing I would check would be the accessories I.E. A/C compressor ( which is right near the filter; see if the noise changes in pitch with the A/C on and off ) Alternator, PS pump, and Tensioner pulley. A whine is usually accessory bearing related. Hope that helps.
Thank you, Ben, for this great instructional video. I'm convinced mine needs to be replaced as I saw smoke coming out of the dipstick a few days ago. I've had smoke for a while come out of the engine oil cap, whenever removed. I have a 2004 xc70 turbo with 145,000 miles. I bought it used and have only just begun to do my own auto work June 2017, other than oil changes.
My questions are: 1-What is the brand name and specs on that cool bending-handle ratchet you're using;
2-What is the name of those crimping hose clamps, and the pliers you used on them;
3-Are there any significant differences between the processes you detailed in this video and the processes for my xc70?
I wrote down everything you said, step-by-step, and once I get it typed up, I'll add screen shots from your vid and post it here for other users, if that's ok by you.
Thanks again.
Hello Bernie,
Hope this answers your questions.
- I'm not sure of the exact brand but its a flex head ratchet. GearWrench sells a nice set at a good price.
- Oetiker Hose Clamp Pliers
- Process is similar but may not be identical. The essential information can be used though.
Having done this job back in 2008 on my 95 850T, I wish you had this video up then, because from my own memory, I don't think I did my PCV valve job correctly. I was using the Brickboard.com's instructions. And I have to concur with the poster that added that this job is a PITA. It defines PITA nicely. And my dipstick tube has condensate in it yet again.
Awesome video thanks - can’t believe you do it so quick - not looking forward to it but this helps big time!
You're welcome! Glad we can help! Just take your time with it and I'm sure you'll be able to get it done!
-Jacob
Hi FCP,
I'm currently having trouble figuring out how to pass my emissions. First thanks for all your help w/ your videos. They're great. My NO (smog) test was the only portion of the video I failed. I have a 98 S70 Volvo. I understand there's no EGR valve. Didn't know what else I could look at to help. I checked for vacuum leaks at most places I could see w/ carb cleaner, but didn't get any change in engine idle. I bought some seafoam to insert in a vacuum line and the gas can to help. Any suggestions?
Thanks,
Kyle
Hi Adam,
That bottom bracket can sometimes make things a bit difficult. My recommendation would be to loosen the manifold and bracket, while keeping the bracket loose, tighten the manifold and then the bracket after. This should ensure that manifold doesn't have anything in its way preventing it from sitting flush. I hope that helps - Jason
Hi FCP Euro, i just completed this replacement yesterday with a kit i recently bought from you for my 2000 C70. Today i turned the car on and warmed it up to test the pressure. Unfortunately, the car tested with pressure still. I used the glove test and also saw smoke coming out of the dipstick. Do you know why this could be?
+music buy Are you sure the lower block hole was not plugged? I always run a little oil through it with a hose to make sure is flowing.
The reason he didn’t answer is the video is very old. He isn’t checking for new questions about this most likely. Make sense to you? Lol. Give youtubers a break Brother. They don’t all make money off this. And work full time jobs and have a life. WOW.
I just turned my dipstick tube into a vent. That goes into a oil catch can . Works great! Fix cost ZERO! I got the car for free. And im not spending one red cent more than needed.
You'll want to check the crankcase vacuum at the oil dipstick to see where if you have negative or positive pressures after the replacement.
A quart a day is a lot of oil to be losing from the dipstick. But it's a small fairly easy seal to replace. It might be worth trying then seeing where you stand.
You know, a $5 PCV valve would have sufficed just fine. Derogatory comments aside, I'll be doing this on a non-turbo soon and I appreciate the step by step. I've been messing with Jap cars my whole life so this is all new to me.
You'll want to check for vacuum leaks and maybe clean the throttle. Also, disconnect your battery for about an hour to reset the adaptives. Hope that helps.
that was absolutely amazing job well done I have to take a nap now you may be tired keep up the good work
thanks man i did it.......took me a couple days as it was my first time......video is amazing thanks again
You could have a clogged oil drain passage to the block or a sliced/loose hose. Or it's possible you could have installed a faulty vacuum valve that could be faulty. Hope that helps.
There certainly is, and smoke could definitely be indicative of a faulty valve. We show how to replace it in the video. Hope it helps.
Fuel rail also has a separate rubber seal that sits between the injector and the fuel rail seat. Maybe check it didn't fall out if the injector is separated from the rail. I lost one when I did this. They're about $10 each from a dealer!
Sigh....I used this video as a guide to do my PCV system and into my car (95' 850T wagon) as far as lifting the intake manifold then - wait a minute, what the hell is this carbuncle hanging off the bottom of the manifold? I discover that it's part of the EGR system!!! Hmm, interesting. No mention of that in the video. Wish I had more space to describe what a gigantic cluster the project turned into. Thanks FCP!
They're not cheap, a shop should be able to activate the fan speeds for a small fee, and that might help diagnose your issue.
This is much more work than simply replacing a PCV valve like on an American car. How might one know that this task of replacing this PCV system is necessary? When the Engine light goes on? Rough idle? Does the oil separator box ever get filled? (Oh, but this video is very helpful, my Haynes manual doesn't even write about the 850 PCV system.) Thanks.
Hello John, some of the symptoms include:
-Noise (whistling) - Noise due to high pressure in crankcase. This noise will stop if the oil filler cap is removed.
-Poor Drivability, clogged crankcase ventilation can reduce the engine performance
-Uneven Idling Caused by clogged crankcase ventilation
-Oil leak from engine seals due to restricted crankcase ventilation
-High oil consumption/noise from Turbo
Dont forget the billowing smoke from the dipstick
You can tell if it is starting to clog by warming up the engine, then place a rubber glove over oil filler neck and place a rubber band around the neck to hold it in place. Start the engine, if the fingers on the glove indicate a vacuum your good. If the inflate the change ASAP.
There are some differences nothing major though. Different intake manifolds, throttles, vacuum and breather line routings. Hope that helps!
Purchased the PCV service kit from FCP. You changed the dipstick oil tube O-ring wouldn't this also be the appropriate time to change the injector O-rings as well? I may just be over thinking things may be a nice addition to the kit though. I'll let you know how this goes as well as how long it takes. Great video.
nickolas swader It's more of a personal preference, not a must. Inspect them, if they seem worn then replace them.
after watching this vid..didnt even think twice,i subd immediately!!! great video
Fcp euro seems to be the only place I can get certain parts for my car too.. eventually I’d like to do a diesel swap but again idk if I could even get that in the us
Can you do a video for replacing a timing belt and components for Volvo Xc90 t6, 2005. Or do you have a video already that the procedures would be essentially the same. Thanks and keep up the easy to follow videos.
You may have to remove the coolant line that goes through the timing cover. If you have that setup, my advice is to remove the hose from the coolant reservoir side and slide the timing cover around it.
It was so painful watching him bend the hell out of that fuel rail. You can easily remove it by taking off that one fitting and the small clamp. Lol very helpful video to say the least.
lol so dont bring car to mecanic lol
I hear ya, I did my injectors years ago can't remember how I did it, but seeing that rail go like that wow!
Excellent video - Thank You
I am about to change the PCV system on my 1999 C70. How many man hours did it take u start to finish ?
Very excellent video, as always. Thanks. When/how often should this maintenance be done?
As a 850 T5 owner just want to say a very big thank you, you are two piece of God, man! I have one cuestion: what is the PCV box exactly? I mean what does it stand for and what does in contains? Is it electronic stuff or just a connection point to the housing?
hamaramadarat A PCV (positive crankcase ventilation) breather system is designed to regulate hazardous waste from your vehicle. As your engine runs, combustion gases escape from the combustion chamber, finding their way into the crankcase of your engine. This unused combustion gas, also referred to as “blow-by,” can be a major cause of smog. A PCV system prevents pollutants from escaping into the environment and vehicle manufacturers started fitting engines with a PCV valve to ensure that gas remains contained within your vehicle.
It's not a belt kind of sound and It's not the PS pump for sure.
I haven't tried opening the oil filler cap to see if the sound disappears but I tried a latex glove on the fill hole and it inflates, smoke also comes from the dipstick tube.
I'm willing to bet it's the PCV making pressure on cold days and the sound is from forced air bubbles or excessive pressure buildup somewhere near the oil filter :)
Very timely, I ordered this kit yesterday! Thanks!
thank you! managed to get it done in a day!
Great job!
I've been ordering parts and using your videos for awhile now. Thank you for all your help!
One question, this PCV replacement process is basically the same for a 1998 S70 base model, correct?
Thank you for the support, Alexander! We're happy to help! Yes, you are correct, the PCV replacement process is basically the same for your 98 S70. There are some differences in the vacuum lines and air hoses on the Turbo vs NA model but otherwise, it is the same process!
@@fcpeuro I have an 850 2.5 10v NA. Can you list some of the specific differences?
Practical information! Thank you. I replaced the flame trap along with the PCV box. Do I need to check anything else?
This is great! I am doing this on my 2001 xc70...is the procedure more or less the same, or is there additional steps to be aware of?
Thanks!
It sounds like you may need a new fan. Do you have access to a scanner so you can activate the stage 1 and 2 functions?
Ben, thanks for the great video. It is very helpful. You make it look so easy!
Wade
You're welcome! Glad to hear the video helped you out.
I believe most manufacturers recommend it's done every 50-80k miles.
Is it the same procedure for a 2002 Volvo C70 Coupe Automatic Trans? Great video, and great detail !.
Diyrobert has a good video on this as well . There are a couple differences in the s40 2002 1.9 but the process is similar
my car is a volvo 98 v70 5t. didnt see nothing change. well i need to change that part too. omg i need a man help. theres things i can do , but theres other part little hard to remove .i did like the way you it. easy and clean. nice job !!
Nicely done, will revisit this video when i overhaul mine. I'll have to replace the timing belt/water pump, radiator and I think by removing the radiator/shroud first, will give me tons of room to work around the manifold.
Now, has anyone ever replaced just the pesky vacuum elbow that sits right in between the power steering pump and intake manifold? The one with one port larger then the other that fails and triggers a P0172 code! I'm wondering besides long needle nose pliers, what other methods have you used?
I think you've got it. Long needle nose pliers and some patience.
what an excellent instructional video!!! thanks brother
Thanks Ben, my dad just gave me his old volvo 850. Really nice car and has all the features amodern car has. Trying to get my head round the my new car. What is a PCV breather system and what does it do?
It would be nice to know what tools you used so we can own the correct tools. I struggled removing the two 12mm bolts under manifold from below. You made it look easy doing it from above. What were the tools? I also struggled with the first manifold bolt on the passenger side (US) .
Great tutorial video, nice professional job, Is this job only on petrol models?
Glad you like the video. Yes, this is for petrol models. Diesel engine will be different.
We've added it to our list!
This is a great video. It is thoroughly detailed. Do you have one performing the same service on a 1995 Volvo 960? I have the searching idling problem and someone said it was the intake gasket.
Great video FCP. Will be attempting this shortly. Quick question for you guys. Does a 95' 20 valve non-turbo 850 have an egr valve? If so, does it have to be removed to get the manifold off? Thanks for your time.
Excellent work, thanks for sharing.
Van Troy Osorio It may be, but the first thing I would check for would be for vacuum leaks. A vacuum leak is more likely to throw off the fuel trim. Hope that helps. (Sorry for the strange reply, it wouldn't let me respond to your actual comment)
can you make a video like this for 740 volvo turbo B230FT engine..? and What kind of oil i need for me M46 Transmision..?
Brian Quero What year is your 740? A VIN is always helpful too.
Brian Quero Any oil will do in any gearbox before M90 as long as it is for trans, im sorry to tell you but if you cant fix a B230 you are really bad...
Hi FCP Euro, i just replaced the pcv system on my 2000 C70 with a kit i bought on your website and i did the glove test on it for pressure and the glove blew up. I also checked the dipstick and smoke was coming out of there. I took it for a 13 mile ride and retested it and same thing. Any idea of what it could be?
great Video ! However I am trying to determine whether I need to undertake this procedure. I have done two tests, Firstly I removed the dipstick end with the car running and looked for smoke.... which there wasn't any. Then I put a glove over the oil cap to see if it inflated and it did. So i don't know what one to believe
josh grantham The Glove and dipstick tests are only used for a general indication of if you have positive pressure. To gauge an accurate reading he'll need a low caliber vacuum guage / Manometer.
Great video! A poster on one of the forums made mention of a banjo bolt somewhere, though from your video I only see you interacting with basic hoses and clamps. Is there in fact a banjo bolt somwhere in the system?
Also, if i want to remove the fuel rail instead of bending it back, is it connected to the intake fuel line with a basic threaded connector and crush washer?
Great video! I have a 1983 Volvo 244 Turbo and I have no Idea how to get the intake manifold off to get at the PCV what with all the hoses and wires in the way. Any videos that could help me out? There's not a whole lot out there about it.
I'm sorry, that vehicle is too old, I'm not able to find any good literature or a video on the install. Sorry about that.
excellent and very systematic!
For me if it is clogged, I will drain engine oil first and not plug in the drain bolt. Then I will open the top vent hose on cam cover and spray alot of carb cleaner. Leave it over night to let the gum-gunk dissolve. I may spray carb cleaner or pour gasoline fill to the long vent line at the end that connect with PTC. To make the solution liquid fill along the tube, it need to connect extension tube that route to higher position which gravity will do the job of solution filling. After settle one more day, you can check if the clog problem is eliminated or not. If not, then it need to do disasemble the intake manifold for better inspection and replacement the clogged or damaged parts.
Great video, Ben. Thanks you! Wow, do all these apply to a 2003 S40 as well?
Love this video! Any advice for the same job on a 1995 960? I can't seem to get the intake manifold out. Does the EGR have to be disconnected somehow to remove the manifold, and if so, how do you get to it (considering it's under the manifold)?
Ben, Thank you for the excellent video. I have read that the use of a premium synthetic oil will prevent or deter this repair which I imagine costs over $500 at a dealer. Do you agree?
Sam Julier
It will hinder the chances of oil sludge if changed regularly however if any oil is left in a vehicle too long the same results will surface. Moral of the story - change your oil frequently no matter which grade or blend your using.
$890. Just got a quote from Volvo dealer
Yup you should be able to follow this just fine.
