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.

glove inflated during system test, replaced pcv system and cleaned intake manifold/throttle body, replaced vacuum lines, now the glove has negative pressure. So grateful that there's people like you Robert that offer their expertise without ever expecting anything in return. Thank you!
+Drowsy_ Mouse you are welcome.
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.
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.
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.
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.
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.
I had a 2003 S60 that had a real bad PCV problem. When it gets bad, you'll even hear a whistling sound and throw a CEL. It took me 4 hours to replace the stupid oil trap since I had to take the manifold out and it was a bitch to get it out of the car because the metal fuel line goes in through the openings of the manifold. I was amazed at how much nasty goo was in there. Word of advice for you folks with Volvos is to always use synthetic instead if you're using conventional and to change your oil often.
Thanks for sharing.
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 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
Glad they helped, 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.
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
Hey Robert, I have replaced the pcv system few weeks ago, because there was smoke coming out from the dipstick hole. Now there is no smoke coming out of it, unless i rev the engine, when i rev it, some smoke comes out of it, is it normal? I did the glove test today,engine sucks the glove on idle, but when i rev it, it blows the glove a bit and sucks it back in, what does that mean?
Dovydas could mean you’ve gotta old vacuum hose that’s cracked
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
Robert I just completed the PCV system replacement on my 95 960 236000 miles. There aren't any instructions anywhere! The 6 Cyl is different than all others. I've found that while doing this job you need the entire kit from FCP. You also need extra vacuum hoses, clamps, injector seals. Most say to you don't need to pull the intake completely off to get to the pcv box, not the case for the 6 Cyl you need to pull all of it off and clean the entire intake system and since your down there clean the egr valve maybe replace the starter too. Not for the faint of heart as you also need a good set of tools as well. Thanks for the background info. This will be my last Volvo since China bought them the quality of these vehicles has diminished immensely!
China didn't get involved until around 2008.
Robert DIY, I know ford bought Volvo from the Sweds, along with Land Rover, took the technology then sold them. I would like to get another good S90 1998 preferred. I stopped working on my vehicles a while ago due to spinal issues but since the quality of mechanics has dwindled and the cost has skyrocketed, I started DIY, watching your videos has taught me a lot about Volvos. To that I thank you, my next project is seat replacement, carpet renewal and timing belt replacement.
Well, I really don't remember saying that the system could be "CLEANED". Chances are that you have broken tubes while in there trying to clean it. The system simply needs to be replaced. So, place an order for the parts or go by the stealer and pick up the parts to replace it. Cleaning it out... many have tried, few success stories.
Thanks for all the help you have given on my 99 volvo s70. I'm afraid she may be done for this time around. I don't have the cash to fix a major oil leak. Shes leaking so much oil from what may be crank shaft. You have helped her greatly in the past and saved me so much money.
I now know how awesome a Volvo is to have.
Toss it on CraigsList.
After watching video again, I'm going to give it a go myself. Maybe I'll have luck and can save the ol'girl.
Shes worth keeping around.
I will not have a complete video until this weekend. Maybe Sunday or Monday at the latest.
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.
Seen my first feedback video today. The car was coughing oil out of the oil filler neck all over the top of the motor.
Another way to suspect the system is clogged is when you see oil all over the top of the motor when you remove the spark plug cover.
I just swapped a 2000 V70R motor into my 1997 850 AWD..... I put a new-er (clean) PCV box on it... new hoses.... and it FAILS the glove test horribly! Turn the car on and it blows the glove up immediately at idle.
What could this be? I'm at a loss here :(
Very good video. I have not purchased my first Volvo just yet, however, in the coming month I hope to. Your videos are educating me to a level to keep an watchful eye on people trying to offload cars with several hidden problems. Also, knowing what to look for may help to reduce the selling price. Kelly blue book is typically utilized for pricing and rarely questions these issues. Many of us DIY mechanics can perform these checks without taking the vehicle to a garage. Even if you had to bring the vehicle to a garage, it is very helpful to have an idea of symptoms so you are not taken advantage of by a garage telling you that you need a brake job when in fact your PCV system needs to be serviced. I recall meeting a lady once, who owned a Ford Escort, it was making a low pitch rumble noise from the rear of the car, the car had 40,000 miles on it. Margaret took the car to a garage, the mechanic told her the wheel bearings needed to be changed. Margaret phoned me, told me about the garage findings. I drove the hour up to Albany, pulled off the drivers side wheel and showed her the hub. No issues, none, it turned out the noise was a muffler heat shield vibrating against the frame. I repositioned it, noise gone. I have watched more than 5 of your videos thus far. Becoming better armed and educated of what to look for when I finally get that chance to go an look at Volvo’s. Thank you..
Thanks for watching.

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 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.
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!
Thanks Robert, I remember the Wheeler Dear show was once mentioned about this test, good thing that I found it here for the test other than spent tremendous amount of time to look for theirs, have a good one bro.
you are welcome.
It could be blow by. You can do a compression test to test compression. Did you replace all of the vacuum lines when you changed the PCV valve? Any cracked or broken line can cause blow by. Also, when the system is replaced on the Volvo's it usually takes 500 to 1,000 miles for the smoke/vapor to clear up.
Y
I plan to do one soon. The best thing to do is replace the system.
Hi Rob I put the pcv/oil separator box back in after cleaning it out with a diesel soak and shake with ports closed then a reverse flush with a hi pressure gerni water Karcher if you call them that over there.....WORKED PERFECTLY LIKE BRAND NEW NO AIR PRESSURE sound being forced out when i shut engine off. Take care brother
You are welcome. Hope it saved you some time and keeps your car in tip top shape.
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 robert your knowleaddge is still appreacated today !
Awesome! Thanks for watching.
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.
Yes, your car may also have a part installed in the intake called VVIS which is a valve in the intake manifold that closes 1/2 of it off sometimes. You should take the entire intake manifold off, not just push it to the side. The EGR valve is bolted to the bottom of the manifold, and you should take it off, scrape off any carbon buildup, then install a new paper gasket. This will also require you to pull the throttle body off so you should get a new gasket for that as well.
I should have a video up showing the entire process within a week. I'll post a couple of clips in a few minutes.
Thanks for watching and subscribing.
Good to hear. Keep it in good shape.
Thank you for showing me how to check my pcv on my 960. Arthur.
You are welcome. Thanks for watching.
This was a great help in diagnosing my problem. It probably saved me 100 bucks or more in shop time.
Yep.
Very helpful video here.
It appears my car has this problem.
Runs great but blows oil out the tailpipe big time.
I was bummed thinking my Head Gasket was blown so its been parked for over a year.
Fired right up, click, boom. Thanks for the tip and your other Volvo vids too.
Cheers.
You are welcome.
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.
Thanks Robert your video may have saved me further hassles...My 850 T5 is going to the mechanics' for oil leaks shooting out behind the main seal AND out of the turbo, I understand now why this is happening, Ill get them to service the PCV while its there. Cheers
I'm amazed as to the number of mechanics that work on Volvo's that do not test and service the PCV system.
DOES your CEL light work? Does it come on when you turn the key on before starting the car?
Great video! My 850 and V40 both have PCV issues. I had no idea until this video. Somehow I overlooked this. Thank you.
Likely the most overlooked maintenance item for white block Volvo's.
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.
Thank you for watching.
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.
I think it's the best home test. If you are still inflating the glove, you may have internal engine wear causing blow by (head pressure). Do a compression test. You can go to my channel and hit the search glass and type in "Compression Test". If compression is good you should re-visit the PCV job.
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.
Robert, I replaced everything on the PCV system, and I'm still having positive pressure in my motor and I don't like it lol Made sure all the ports were cleaned out from the block and everything. Even took a tube and stuck it inside the lower drain port and blew air into it to see if the square port was clogged inside the pan ( I came across this method somewhere online). It seemed fine when I did it, i could blow air onto the pan, so I thought that is not my problem. If that is not my problem, then I understand it could be either worn piston rings or head gasket failing. My plan it to do compression check and see where I'm at there, and if that looks good then drop the oil pan and check that drain port. I have a 1995 Volvo 850 GLT and it has been very well taken care of. I bought it 2 years ago from a guy and he had all the service records.
Did you do a compression test before doing the job?
@@RobertDIY No, I haven't done one yet. I'm gonna do one within the next few days. I'll let you know what the numbers are.
@@RobertDIY I just did a compression test, and I got 140-150 for all cylinders dry, then did a wet test and got 184-186. Is this what worn piston rings look like? You think my motor is on it's way out? I ask bc I was going to replace the shocks and I dont want to if the motor is bad.
Another excellent video. Your style of explaining things, is propably the best I've heard in any youtube videos. Very understandable. We are definetly on the same wavelenght. And I love your accent. :)
Lol, thanks for watching
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.
Nice video, no bullshitt, no stupid effects and dumb music. Just what's important.. I like that.. 👍 thanks
You are welcome
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.
So glad i found u i just got a s40 and am replacing everything to help pass emissions
Thanks for watching.
Your videos are excellent! We're going to try the two tests right now.
Thanks for watching.
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.
I would do a compression test. Maybe you have a bad head gasket or a worn piston. These cars actually run with bad head gaskets for a long time. My daughter drove with one for over a year. Keep the coolant topped up and it'll keep going.
Did you remember to clean out the ports in the motor?
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
Volvo should really consider sponsoring you man!
They can kick it off with a new V90 and some parts for Panther. lol
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 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.
Going to check a nice 200k km 850 tomorrow, i hope it ain't trashed.
ua-cam.com/video/L4g-w4OXeBw/v-deo.html
@@RobertDIY Yes sirrr!
Good. However, that is strange. Usually the o2 sensors will cause a code before they get that bad.
Thanks, hope you're good.
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.
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...
Huh? If your oil light is coming on while driving, you likely have a seal problem on the oil pick up. You need to drop the oil pan and replace the seals and gasket on the oil pick up.
Thanks!! My breather hose had a hole right through it.
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.
Man you are doing great videos always
Thanks for watching
Thanks for your articulate tutorial guide
You are welcome!
Could be a number of things. Do you have a CEL (check engine light)? If so you should have the car scanned for codes.
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.
Thanks! I'm working on an 850 that seems to be leaking oil from just about everywhere. Makes sense
+Josh Denham thanks for watching.
Hi Robert- Thanks for the videos. I did the glove test and the dipstick test on my ‘99 S70 with 140,000 miles. Glove sucked in and no smoke from the dipstick tube. Had some oil under the spark plug cover and in the spark plug wells. Replaced oil cap hoping that was the problem. Think the PCV might still be bad even though I “passed” the two tests. Thanks!
Really? Why would you NOT believe the test results?
Robert DIY whoops haha meant to add a question mark to that last sentence to get your take. Yeah was just wanting to get your take as an extra precaution. Thanks for replying and take care!
Thanks for all the great info again. Going to check my PCV system first thing 2mrow.
Good deal. Keep them up and they will last a long time.
great video Robert
Thanks
very helpful. never heard of the glove test. pretty smart!
+Joshua Schofield thanks for watching.
I had to delete last message due to the specifics.
I just Bought a 1994 Volvo 850 Turbo 190k+ miles for $1300.00
It has a small, and when I say "small" I mean super small oil leak.
Details:
So it's not leaking in massive amounts of oil. It's not even leaving a puddle unless it has been driven extensively through the highway.
It's leaking where the oil pan is located. The bottom of it is soaked in oil, I reached down under it after it was degreased and my hand was soaked in it.
I am thinking personally that it is just a worn out rear main seal. However the experience of a car enthusiast such as yourself could tell me where my next step should be taken.
Thank you sir
+Adam Sandifer Is the PCV system serviceable? You'll need to locate the leak.
+Adam Sandifer The PCV looks good. I recently learned that the PCV test should be done when the engine is warm or hot. Also, you will need to find where the oil leak is coming from. Is there oil at the bottom of the distributor cap?
Thomas Crown, I am not able to reply to your message. Maybe you have some kind of communication lock on your account.
With these great videos my mechanic is going to be lonely guy.
Thnx million Robert. I just bought a used S70 2000 a1 condition. Will be using your advice.
Mike
You are welcome.
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.
Wow, so the glove does not inflate any more?
So you had a CEL?
But the good think is that you now know and can get it fixed before you blow oil everywhere.
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.
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.
best explanation yet....

Thanks. The test is so simple and fairly accurate too.
Glad it worked out for you.
