More details: • Everything you need to...
The Volvo PCV system is one of the most neglected maintenance items on the I5 cars. Failing to maintain this system can cause major oil leaks. I blew one of my cam seals one evening and lost 2-1/2 quarts of oil in just 2 miles. If you do not know when it was serviced last, replace the system today.

And from the looks of all the comments I'm not the only one who thinks you're worth your weight in gold!! Thanks!!!
+Ross Nroll you are welcome.
@@RobertDIY he ain't lying robert
I'm trying to get around to doing a PCV video. One of the first things in doing my video would be to recommend a compression test prior to doing the job. It cost $150 for the parts and takes most people 4+ hours to do their first time. A compression test on an old car is in order before putting a lot of time and money into them. I do one every 50,000 miles.
Hey Robert you're the best thank you for the information. I replaced my flame trap and nipple after which my 1995 850 passed the rubber glove test! Man I'm so happy about this I'm gonna order me some leather seat covers ;) This car is in great shape at 168,000 miles and I plan on keeping it, great city car, fits in parking spaces no one else but an electric car can. Some months back I followed your instructions and did the timing belt, water pump, tensioner and the pulleys, also did the drivers side seat belt, couldn't have done it without you man thanks again the videos are invaluable!!!
Keith VolvoEightFifty Very cool. Thanks for watching.
I will check that out.
As for the PCV system, the box is the strongest link in the system. The only reason I pull them is because I need to make sure I clean behind the box, make sure the ports are clear. The main problem with the system is that the lines are clogged, damaged, leaking, etc., stopping the system from venting properly and creating the vacuum it is suppose to.
I think you should put up a paypal account so we can donate some $$$ your way for all the money we're saving.. Its cost me over $600 for a sensor once that I could have just cleaned had I seen your videos or did some searching before hand. I'd much rather give money for your honest lessons than these rip off mechanics!!
+Ross Nroll I have a link on my website. Thanks for watching, I'm glad you are saving$$$ now.
Ross Nroll your welcome to pay for my honest mistakes,I make enough of them on a daily basis lol
Thank you Robert for your many helpful videos. Like many I'm trying to keep a great older Volvo on the road with a limited budget. Your tips and tricks really help!
+rjohnston79 good deal.
All of your vids have helped me so much. These cars are actually extremely easy to work on if you have the replacement part on hand. Mine has been solid with one $47 repair and one $153 repair, parts only, thanks to you good sir.
Xyla Bear Glad the videos help. Thanks for watching.
Thanks a million for posting this. I had no reason to suspect a problem, but I thought I'd check on the PCV system in my wife's V70, as it's getting close to needing a timing belt again. I bought the car 3 years ago. At the time, one of the selling points is that the PCV system had been professionally serviced sometime before purchase.
Anyhow, I was able to confirm that the PCV system is indeed healthy. One follow-up question - what's the typical service/replacement interval on these parts?
Leave them alone until they get clogged or a part breaks from someone working near them.
Will do. Hopefully, it'll stay healthy for a long time to come.
Oil changes. Synthetic is better.
Robert, I was checking out a S70 sold as junk today. Car starts, but after ten min or so, the idling engine started to crank unevenly. It goes faster then slow then fast, rhythmically. Is this a representative sign of what issue?
@@ejshelby5460 I'd start with looking for a vacuum leak, particularly if it's a turbo
I just bought a Volvo this morning. Your videos were beyond helpful in my purchase decision. I'm amazed at how many videos you have on this car. Your UA-cam channel is more helpful than a Hayne's manual. And probably more accurate.
Real life. Thanks for watching.
Yes you can DIY. There are several topics on doing the job. You can do a Google Search "Volvo PCV System Replacement" and find a few good topics. It takes about 6 hours for a first timer so do make sure you have time to do the job.
Glad they helped, thanks for watching.
Quick question. During the glove test the glove gets sucked in at idle but when I rev the motor it blows out. What does this mean? Your videos are awesome and super helpful! I go straight to Robert DIY when I have a question now! Thanks!
I'm not sure. There is a chance that you are experiencing piston blow by. You can do a compression test to find out.
How to do a compression test on a car motor. Volvo 850, S70, V70 through 1998 - Auto Repair Series
Please let me know the results. That way I'll know for future people. So, my thoughts right now is that your PCV system is in good health, but you may have a worn motor or piston. If your car is a turbo, the numbers should be between 156 - 186 psi. If your car is NA then numbers should be between 185 - 215.
Thank you Robert,you helped me several yrs ago diagnosing bad fuel pump relay.I just bought a 2000 s70 and it has a major oil leak,looks like from up under timing cover,perhaps bad cam seal,blown out from clogged pcv.Although its 10pm,gonna get out there and start taking it apart.Thank you again my friend !!
Thanks for watching
Enjoy your videos. Just bought a 1993 850 GLT. Service light was on & watching your video of how to reset it worked perfectly. Look forward to your videos helping me resolve more situations as they come.
Alan Markwalter Good deal. Hope you get a lot of use out of it. - ua-cam.com/video/-2oIeIhpV44/v-deo.html
Mr. Robert, I have a 95 Volvo 850 Turbo with about 137k on it and I did the tests that you showed in the video. My car did exactly the same thing yours did in the video! I'll take that as good. Thanks for the simple steps and quality!
Good deal. Now you should check your timing belt and heater core.
Just replaced the timing belt so heater core is next. Thanks!
I plan to do one soon. The best thing to do is replace the system.
Hey Robert, Excellent videos. Thanks so much. And congrats on the 200+K on the wagon. I have a 2000 S70 and do not know if my PCV system has ever been serviced. I am the only owner and my "old fashioned" mechanic just does what he needs to do, I don't ask questions, he keeps my car running and I pay him. I appreciate your videos because it is great for those of use who don't know too much about the Volvo engine. They are great cars, but can be a bear to repair. Great accent btw.
Wade
Thanks for watching. I'm at 329,000 on the wagon now. ;) Keep the coolant and oil good, the rest is minor.
Thanks for watching.
Hi Dovydas, for some reason, I could NOT replay to your message. Likely a setting in your account. At any rate, as the video explains, I do NOT use NOR like the smoking dipstick test. The oil system gets hot and will smoke. Smoke is NORMAL, that is why the system is designed to trap and recycle the fumes. So, it sounds to me like things with your SERVICED system is working very good. Move on to another issue, we all know there is one. ;)
Thanks for a quick reply, and I got one more problem. When the engine is idling, I can feel some vibration while sitting in the car, the rpm needle is jumping up and down a little, what could be the cause of that? If I disconnect the maf sensor, rpm jumps to 1000 and it seems that the vibration is gone. I cleaned the maf sensor and even put another one from other volvo 850, it didn't help, I think it's not the cause. Maybe I should change the spark plugs?
When was the last time you replaced the spark plugs? - ua-cam.com/video/azZ6HAjRihk/v-deo.html
Thanks for watching and subscribing.
Valuable, valuable information!! I just looked at a 2004 XC90 last week. 2.5T engine. I pulled off the oil filler cap and saw some white smoke coming out of the oil filler neck. Not a lot of white smoke, but there was some and it flowing out steadily while the engine was running. The car drove fine, but the white smoke was enough to make me pass on vehicle. This video sheds some light on what may have been going on with that vehicle and some issues to look out for before purchasing a vehicle. Thanks!
Not sure if that showed anything.
I went ahead and pre-liked the video. I mean, when has Robert ever been wrong about Volvos in the past? Great explanation, bro!
I appreciate that!
I love your videos. You are the best Volvo guy out there!. I do wish you would use a 2 foot bright color pointer when your pointing down inside the engine. Most of the time I see what your talking about, the end of this video ( the blue glove) was easier to follow then the early parts. As always thank you.
+Alan Newnham ok.
Thanks for all this info I almost bought the car that it has all the problems that you were talking about from the smoke coming that top of the engine And they told me there was nothing wrong with it... and thanks for you video I find out there was something wrong with the car
luis sarabia Good deal. Issues can be fixed but it's good to know the issues before you pay.
DOES your CEL light work? Does it come on when you turn the key on before starting the car?
Thanks for the reply. I did a thorough clean, found very little residue. The old PCV was in bad condition so it needed to be done. It has reduced the smoke but there is still a smell of fumes when the car is warmed up & only then. I'm not burning or losing any fluids, none. The plugs are new & clean. I will compression test & clean the PTC valve. I did not check or clean this when I replaced the PCV piping.
If you have any other suggestions, it will be appreciated.
You should also double check the intake tubes. If one of them are loose or not connected properly, it will not start or run properly.
Yes I am. I may do it at the junk yard or the next time I need to service one. I'm a little pressed for time right now so I don't see it happening within the next week or two.
Thanks so much for this great tip! I've had many Volvos & the PCV is a known weak spot. I'd like to avoid replacing the PCV unnecessarily (a beastly chore on a P2) so this is a handy diagnostic. Thanks again.
+Katy Kirkpatrick Thanks for watching.
Nice video, no bullshitt, no stupid effects and dumb music. Just what's important.. I like that.. 👍 thanks
You are welcome
96 850 R , I finished the pcv job, and everything went well but still have the mystery part. I got the car a couple weeks ago, so not sure if it's something that was just hanging around from another job. looks like it's had a new radiator and starter. part doesn't seem like it's part of the manifold or pcv. it's basically a 1"x1" cylinder ( like a donut) with a metal body, copper wires inside that go to to leads on the end, and a plastic sheath that looks like if you insert it in a hole it will keep it in... I can send a pic, . anyway I finished the pcv job at 1am and had to drive it home and everything seems to work fine. hopefully the pcv job slows down the rear main seal leak or I'm going to be asking a lot more questions... timing belt is next...thanks for all the great videos!
You are welcome.
Good to hear. Keep it in good shape.
Robert, thanks for the video. I performed the same glove test. My 850's PCV system was good (not clogged).
+Michael Chitwood Good deal. Keep up the good maintenance.
Thanks. I had smoke coming out the dipstick and a blowing glove. Guessing this is the cause of my diesel smells and my turbo issues... I hope its not gone to far with my seals!
I really wish the internet could scrub the process of people checking the dipstick. That is so useless.
Hi Robert, I just came across your Site & Vids... what a great resource. I am an Aussie, I have a 97 Volvo 850 wagon, with 380+ K Km on the clock, and serviced by a (ex-) Volvo mechanic every 10k with a 5k oil change. It has never let me down, but is starting to use some oil. No signs of anything wrong, no smoke, and my mechanic says to just keep it topped up. It runs like a dream, and I will have the ABS module fixed in a couple of weeks by an auto electrician. The Fault light comes on too soon, maybe an O2 sensor. Those are my only 2 issues, but got them sorted, I hope. My niece has a 2006 V50, goes great, but the ignition key get stuck occasionally - a real pain. Anyway this is just to say keep up the good work - I have subscribed, and will enjoy looking at your Vids. Cheers
+Peter MultiTrum Nice, thanks for watching.
So glad i found u i just got a s40 and am replacing everything to help pass emissions
Thanks for watching.
The problem with the oil box plugging is almost eliminated by using synthetic oil like Mobil 1. I cleaned the throttle body and the oil box at 100,000 miles and the box didn't have much in it. We cleaned it out using hot water to make a strong solution with dish washing liquid. I let it soak for about an hour and then sprayed Simple Green inside. Rinsed well and the box was very clean. Cleaned the throttle body and put in a new set of Volvo plugs. My XC 70 runs like new.
+John Ferguson Cool, how many miles do you have on it now?
Robert DIY 116k and it still runs like a top. The one piece of advise I can give is to change the fluid in the Haldex unit (XC 70). Volvo says that it last forever, but that's bull. The fluid was loaded with clutch material when we opened up the case. Changed the filter and the four wheel drive worked beautifully again. The ABS is showing a strange intermittent failure and throwing a ABS check light. Do you have any suggestions? I saw a You Tube video and it seems that the plastic case warps with age and some pins inside start to lose contact. Ever seen that? Thanks, love the channel.
+John Ferguson What year is the car?
+John Ferguson ua-cam.com/video/0zV8nGeGukQ/v-deo.html
Thanks very much for the detailed upload. Used it to check mine and unfortunately it does need replacing. Why they hide a serviceable part like that in such a awkward place is beyond me.
Because it can last forever if the owners keep the car serviced.
Hi Robert. I have the parts on order and will be attempting this when they arrive from FCP. Never done this before, so keeping my fingers crossed. I have a 1995 Volvo 850 non-turbo with 175K.Bought it used so I don't know when this was done. I'll start in the morning and hope to finish in one day. Using the glove it was filling up the fingers, so I know I need to do this. Thanks.
Ricky P. It is really not bad, just a little time consuming. Make sure you clean out the EGR stuff.
Robert DIY
Will do.
Good. However, that is strange. Usually the o2 sensors will cause a code before they get that bad.
Thanks Robert - dealing with some of these issues at the moment. I'll check out other vids of yours too
Mutt1961 Thanks for watching.
Thanks! I'm working on an 850 that seems to be leaking oil from just about everywhere. Makes sense
+Josh Denham thanks for watching.
Thanks Robert. I just checked my 2002 V70XC and it's sucking the glove in. I put the same glove on my 1995 850 Base model (with the new leather power seat interior) and it shot the glove off like a cannon. Looks like I'll be doing lots of work ahead on the 850.
LOL, Wow! I'm surprised that car doesn't need the cam seals.
When you replaced the cam seals on the XC, did you use Volvo seals?
I was traveling cross country and had the nearest garage do it. Not sure but I highly doubt he used genuine Volvo. I'm going to order the mega timing belt kit with the new camseals.
Man, I would NOT do that. Cam seals need to be Volvo. Are you talking about the 850?
I'm definitely going to go with Genuine Volvo. The 850 needs the seals more than the V70 right now.
But the good think is that you now know and can get it fixed before you blow oil everywhere.
Hey
Rob, I have a 2000 s80 t6 and my car is smoking out the tail pipe like an old time mosquito truck. I'm going to try the glove test right now. Goes to show you learn something every day.
Probably one of the turbo's is gone.
2003 Volvo XC90 T6 AWD Smokes and has P0234 Code. Bad turbo...
Your videos are excellent! We're going to try the two tests right now.
Thanks for watching.
Thanks, hope you're good.
Thanks!! My breather hose had a hole right through it.
Yes, a compression test. This is not a fact but just an example. Lets say that a motor in good condition will blow 20 units of air per minute. Lets also assume that the PCV system is designed to handle 25 units of air per minute. Well, a motor with worn pistons may produce 35 units of air per minute, which exceeds the system design, likely on purpose to let you know that something is going wrong with the motor before it leaves you stranded in the wilderness somewhere. Do a compression test.
I’ve got fuse 14 or 15 which is emissions system and air conditioner that keeps blowing a 10 amp fuse. Pulled the blower motor and hooked up to 13 v and it blows. Resistor varies voltage to the connector with a multi meter, but when plugged in it will not blow. Car is in limp mode because emissions fuse is popped. Love some recommendations.
I don't even know what kind of car you have... 🤷🏾♂️
Thanks for this great video, Robert. I will be trying the glove test but I think I know what will happen. We will see how big that glove gets before it takes off for the moon. I know this because we have had some oil coming out of the dipstick hole for several years. I just didn't know why.
Make sure you video that blast off. ;)
@@RobertDIY I cleaned the throttle body and replaced the flame trap and air filter. Put the glove on the oil filler opening and it blew up like a balloon! Smoking out of the dipstick tube as well. Don't have the time to try to replace the oi trap and all that right now, so skating on thin ice! We had the entire PCV system replaced about 40 thousand miles ago. I just looked at the paperwork.
Could be a number of things. Do you have a CEL (check engine light)? If so you should have the car scanned for codes.
Keep up the videos, friend. Great information for first time Volvo owners like myself.
Thanks for watching.
Its Shaun in Vegas....I guess the end is coming between my 1995 850 and myself as it has failed smog in NV twice .....both times for visable smoke through the rear tailpipe. Im pretty sure i have the right weight oil in it , just changed and i use full synthetic,....i did the glove test and it blew it off.
+shaun miller That will do it.
1999 v70 non turbo. 182k, bought 2 months ago. Major oil leak near timing belt. Will changing the pcv system stop the oil leak.
+Matt Kirkland did you watch the video?
I really do not understand your problem. However, if you have to press on the throttle to start the car, something is likely not connected properly on the throttle module.
hi robert, great video! it shows in point what to do. now yet my car is on the road. ;) if it is back, i'll do the test, cause in my mind i think, it will be need a service. best regaards from germany, oldwood
+OldwoodHR Nice, thanks for watching.
awesome video, great information! It's hard to find these around, thanks for the help! Subscribed
Cool, watch the new owner video if you have a Volvo.
My 03 V70 has milky oil and used to only be very little like one small drip on the dipstick. The previous owner said the pcv system was clogged. In the last week, I have seen a rather scary oil leak under my car lately, about 6 or 7 inches in diameter. Then today, I drove for 4 hours at highway speeds and got a dash alert that said no oil pressure. I pulled over and added a quart. I have been adding oil since I got it. It burns (or leaks now) about a quart a month but never gets low enough to alert me. I drove a bit more. It came on again. I checked it, and saw oil everywhere on the passenger side. It took 6 quarts for me to get it home so that I wouldn't run it dry... There was a hole in the hood insulation where the dipstick is. Looks like that's where it came from mostly. But at a quick glance it appears to be coming from the oil separator box. I didn't spend much time looking. I had to go to work. Any help is greatly appreciated! Do you think the pcv system is to blame for milky oil and leaking? Do you think it may be bigger than that?
Are you going to bring it by for me to check?

Really good video, Please keep them coming! Can you please do a vide that shows you how to service the PCV system?
Thanks for your articulate tutorial guide
You are welcome!
thanks... im eddy from malaysia, many thanks to you... very usefull knowledge for me as the PCV system bad on my s80.. just DIY and it cost USD60 for new oil trap and two rubber piping to engine... thanks robert
Hey rob I have a 98 v70 t5 with 200,000 miles when I did the glove test it sucked in at idle but inflated when I pressed the accelerator
Thomas Crown, I am not able to reply to your message. Maybe you have some kind of communication lock on your account.
Dear RSpi007.
Volvo 1996 850 Turbo. I had smoke coming out the exhaust. Done the check with the glove over the oil filler & it inflated. I have now replaced the PCV system with a new PCV system kit. Did the check with the glove again & it is still inflating the glove. What is next?
Man you are doing great videos always
Thanks for watching
RobertDIY, you are awesome, thank you for your videos.
+STG44VOLVO thanks for watching.
Robert, I have a problem with my V70 Phase 1 2.0 litre non turbo 10 valve 180,000 miles on the clock (850 shape) I have done a FULL service myself when I bought it, Plugs, ALL filters, good quality "semi" oil and no "blown up" glove, Mine sucks glove in just like yours!!! it "hunts" when I connect the IAC valve (but only shows a code when its DISCONNECYED) It will sit and rev from 600 to 1500 RPM when connected BUT when disconnected will start and run normally (Fuel consumption is an average of 27.5 MPG combined when disconnected which is fairly normal so i gather and it passes it's UK "MOT" LAMDA is 1.00 which is perfect!!!) checked PCV and all is ok, checked all vacuum pipes, all intact, IAC is operational as no codes thrown up when connected (BUT HUNTS like hell!!!) any idea's please? Thanks Clive in the UK
+Clive Clarke-Watson Either has a vacuum leak at the valve or it is bad.
+Robert DIY Thanks I will double check all you have said......What the valve won't "throw" a code even if "bad???" Anyway thanks for your speedy reply!!! Didn't expect it that quick!!! Happy Christmas and New year from the UK!!!!
Thanks. Some parts take a while to throw codes.
Robert, love your videos. Wish I had started watching them sooner. The PCV breather failed on my '06 S40. It started making this awful whirring/moaning noise. I went ahead and immediately replaced the unit (different process on this model, still bad design!). But I was not quick enough - I noticed some oil leaking around the intake cam sprocket with the vvt actuator on it. So I will need to replace that and the belt and seals. Can I just lock the cams with the cam lock tool or do I need to lock the crankshaft too?
I would advise anyone purchasing a used Volvo with an I5 motor to just go ahead and replace the darn PCV breather because it will eventually bite you in the rear end!
John Nichols Sorry to read about your issues. Locking the cams with the tool is enough.
My problem turned out to be the two oxygen sensors were faulty. This in turn caused too much fuel to be used, thus upping the amount of exhaust & overwhelming the breather system.
Saludos de Perú me es muy importante sus videos sobre sus maravillosos conocimientos de motores volvo yo tengo un Volvo V70 2001 diesel lo compré de segunda mano y después de dos semanas de usarlo se me apago y no lo pueden escaniar el tacómetro se a quedado en 2 mil y suena un relay en la bonba de inyección y e visto otros videos de UA-cam y e podido verificar por el tablero de mi carro que tengo problemas con la bomba de aceite y el airbag porfavor podria tener la opción para escucharlo en español
No tengo experiencia con los coches con motor desel.
ok and is it normal that the car blows up the glove whit cold engine? And whats about the smoke? the car just smokes a bit when im driving not when the car stays with running engine. Thank you for your support.. and your videos are very helpfull, you are the only one worldwide bringing the proplems a the point. Man im writting you from Luxemburg = europe...over here they are just crap
+Nicolas Philippe Yes, sometimes the rings are a little worn and they need to warm up to seal and stop piston blow by. If you are getting smoke from the tail pipe it can be several things. I'd start by checking the turbo, pcv system, and go from there. Make sure you have the correct oil.
I think it will NOT work. The hoses are usually clogged with with a hard carbon build up. The engine port may also be clogged. Also, the diesel fuel will NEVER reach the lines, oil does NOT flow through these lines. They are damaged from years and years and thousands upon thousands of miles of OIL VAPOR. I promise you. many upon many people have tried to get around PROPERLY servicing this system and have failed. What damage might diesel fuel otherwise do?
Nice video, Robert. Thank you for making this.
You are welcome.
You are welcome.
You are welcome.
I HAVE 1999 C70 . I WAS TOLD IT HAS A BAD HEAD GASKET. I WANT TO START THE CAR AND DO SOME OF THE TEST I'VE SEEN YOU DO.. I REMOVED THE COVER OVER THE SPARK PLUGS AND I HAVE SEEN OIL IN SOME OF THE PLUG WELLS ..I NEED SOME ADVICE. THANKS AND GOD BLESS
ua-cam.com/video/jsxPXltMFOc/v-deo.html
Great video.
What mileage would you expect to start having the pcv system serviced at.
I've put almost 300,000 miles on mine and it's still good. If you use full synthetic oil and don't damage the system parts it can last forever.
if oil is blowing out of the dipstick is the motor still able to be saved with a completely new pcv kit? great videos robert, thanks.
Eric Edmonds Two words... COMPRESSION TEST. It will tell you the health of the motor. - ua-cam.com/video/Z0hZELYgOX8/v-deo.html
If you could maybe use a pointer to point out what bolt or item you are talking about removing that would be great
Robert DIY in future videos
juiceman10099 Really?
robert hi I have seen several of your videos I like your explanation congratulations, i write from queretaro
Thank you for watching.
Glove inflates a little bit on my 1993 850 non turbo which recently passed California smog test so the PCV system had to be functioning.
+Happi OK
thanks for the video. im actually heading out to look at a 2005 v70 2.5t today. I know about basic mechanic stuff but have never worked on/with volvos in my life so stuff like this is help full for me. with any luck i can bring it home today. i know this may not reach you in time before i head out but is there anything else (volvo specific) i should be on the look out for on a car this old?
ua-cam.com/video/L4g-w4OXeBw/v-deo.html
Where does that hose showed in the beginning lead? Mine is torn. I have had misfires and a rich running system. I had a leaking cam seal replaced recently so the pcv system is likely clogged. Great video btw. I have used these for months to replace all kinds of things on my volvo.
+NICKELGHANDI which hose?
+NICKELGHANDI ua-cam.com/video/-2oIeIhpV44/v-deo.html
I don't think I was specific enough. It is a vacuum elbow that attaches to a hose that runs under the intake manifold I believe and then somewhere to the back of the engine. Everything besides the vacuum lines have been done in the last 10,000 miles and I have service records dating back to 1998 (when it was new) showing repairs and replacements. Those vacuum lines have been the biggest issue for me.

Thanks Mr Robert from Stockholm
Thank you for watching.
Hi,Replacement the PCV in a 99 V70 is the same has the other older models,don´t you have demonstration video,i see your check video and my system having little smoke,i have to do the replacing
Hi Rob, I pulled the PVC unit off filled it with diesel fuel and shook the hell out of it and let it soak over night then back flushed and forward flushed it with a Kartcher high pressure cleaner. seems to have worked will let you know how it goes when I put the cam seal back in it blew out...check out my vid on the landcruiser carb mod to save fuel and get more power..you could make a few 4x4 owners happy
what would a very thin, small amount of smoke from the dipstick, but good glove test mean? I'm almost 100% that this system was never serviced
Means you should stop doing a dipstick test. I never recommended.
Hey Robert , Hope is well !
When I rebuilt the head on our 99 I replaced the PCV system at 180,000. I was just getting ready to do the belt and water pump at 240000 since I noticed a leak coming the cam seal behind the vvt on the exhaust cam. I may not have pressed the seal in properly the first time but I will check the PVC system to make sure that isn't why I am having cam seal issues. My question is while I was checking the timing marks and getting the vvt spring tension set (after replacing the cam seals/pump and belt) I had to reset the vvt by a tooth. When I removed the vvt cap ( after new seals and running 20 miles)I had a few maybe 2 to 5 ounces of engine oil come out the vvt but had not seen any oil leaks while testing it running for 20 miles. ( P0014 code timing off) Which is why I pulled the vvt back off and reset it with cam locking tool and crank pulley set to block TDC. I had everything set up the first time then hand cranked the engine two revolutions plus went past TDC then hand cranked engine back to TDC all marks had lined up but I think I had a little slack in the belt and it was off one tooth. It looks to me the way the seals work on the vvt and engine block that oil would have to enter the inner vvt and is held in or prevented leaking by the vvt cap? Just wondering if I may need to redo that seal again........ I guess if I run it for a while and do not get any leaks that is the way the vvt interacts with the cam shaft and engine block and camshaft seal..... appreciate your time as always

+Donny McClure please NEVER use the term TDC with vehicles that use marks to align timing, especially these white block Volvo's.
The hub's hold oil so you can find oil in them. They also have 2 seals (I believe).
If you are off a tooth according to the marks, you need to loosen the belt and move that cam so that the marks are correct.
If the belt is loose after you crank it over by hand reset the tensioner.
This technique works great for setting cams with VVT's and thanks for the info!
Basically, consider it to be a three stage process:
Stage 1
Forget the VADIS proceedure for now and whatever you have tried so far
Stage 2
Have
the crank locked in position on its mark. Drop a 6" 3/8 extenstion into
the hole near the starter, turn motor counter clockwise by hand until
it hits the stop.
Cams should locked in position, in line with seam in head.
Ensure all all notches are lined up on the cam pulleys with the timing belt cover.
Timing belt sould be on.
Inner bolt on cam pulley that fixes the unit onto the camshaft should be torqued down (Circa 88Ft Lbs, please verify).
The three bolts for the cam gear to VVT unit should be loose
VVT
unit should be turned fully counter clockwise (bolts will be on the
left of the holes in the toothed pulley when this is done).
If
you cant achieve stage 2, ie the VVT unit will not move far enough
counterclockwise for the three bolts to be at their leftmost limit, then
the center bolt that attaches the unit to the cam needs to be loosened
as their relative positions are incorrect.
Stage 3
Keep cams locked, pulleys at marks amd crank locked\at mark.
Fit the outer "cap" onto the VVT unit (T60 torx), no need to torque it yet.
Rotate the VVT unit clockwise using the cap with a T60 torx until it hits its limit.
Lock the three outer pulley bolts.
Torque the VVT cap (25 lb/ft I think, please verify).
You
should now be in a position where all marks line up and the three
pulley bolts on the VVT unit are on rightmost part of the holes in the
toothed gear.
PS passed the glove test thanks for that tip, I replaced the PCV system at 180000 whe I rebuilt the head... didnt want to repeat that again if not needed! I think my cam seal problem was due to not having it seated properly the first time !
I've got a 2000 v70 XC turbo. It looks completely different!
Aron Kovacs Not much different, you have an ETM in the way on the intake.
You have really coming sense
thanks.
On my 99v70R, the glove used to inflate a bit, so I replaced the PCV hoses and breather box (new complete kit from IPD). Now, the valve cover has plenty of vacuum, but the oil dipstick is pushing out, the car makes a whistling noise and gets horrible gas mileage. What now?
+Dan McBoost Something is loose or disconnected, not sure what, you'll have to find the source of the whistle, that is the leak.
I bought a new PCV system and will be installing it tomorrow and I was just wondering how common it is for some of the other gaskets to be blown? In the kit I bought it comes with the intake gasket and hopefully that's the only one blown.
DrTrevorP Where did you purchase the PCV system? I have a 1998 V70 that's driving me nuts.
Great video! I have an issue with the front crankshaft seal blowing out and leaking oil. The PCV system does not blow smoke from the dipstick and sucks in the glove. What else could be blowing out the seal? I have about 15psi of oil pressure at idle and 60 psi at 3000 rpm. It is a 2001 S60 with the 2.4T turbocharged. I am at my wits end.
Todd Goodwine Have you replaced the seal?
Hey, thanks. This was really helpful.
Hello, Robert! I recently changed my PCV system. After i switched the system it’s still coming gas out off the dipstick and the glove blows up... What to do?
And my motor is ticking, I don’t think that’s normal?
Thank you for making this videos!

Advice appreciated
Robert,
Thanks for the great DYI videos. Very informative. and you are a great teacher knowing how to explain things in an easy to understand way.
A question-- I have a volvo s60 with 150k miles. there is some oil under the engine cover. When I used your rubber glove method to test the engine pressure, the glove blows up. Do you think the PCV system is the culprit? If so, how soon does it need to be replaced?
Thanks
I'd check compression just to make sure the motor is not worn but chances are, the PCV system is plugged.
Needs to be done ASAP because you are in danger of blowing oil seals.
Thanks!! Appreciate the time you took.
+eric laidlaw you are welcome.
What do think about pouring a liter of diesel fuel in the engine to clean out the oil pcv
Hey Robert, I have been doing some research about servicing my 1994 850 turbo PCV kit. Some people mention that i should be also cleaning EGR valve and replace the EGR gasket too. Do you happen to know how to do this? what to look for?
Robert DIY I appreciate all the info u give my 1999 Volvo V70 2.4L nonturbo 5cyl.black vacum broke off how can it be fixed ? Thank You if you can help me.
+Rob D Replace the part.
