- Valve seals in an IC engine controls the leakage of engine oil from getting into the engine manifold and holds the gas pressure inside the manifold from leaking into the crank case. These are symptoms when valve seals in your engine goes bad or worn out.

Every question I’ve been looking for has been answered , no engine oil spot yet but I def need to replace my gaskets and valve seals
I replaced valve seals myself having had the described symptoms and now no more blue smoke. Should have done it long ago.
Glad to hear from you mate
Same thing here messed up my vehicle
Well done mate! I own a 2011 Subaru Forester and only get the white smoke in the morning for about 50 seconds then it goes away. Some days I don't see the white smoke however, I got a feeling that my valve seals are either loss or needs replacement. What do you think?
Is it difficult to do it myself at home ? Do I need special tools?
about to do it to my 2005 tahoe losing a lot of oil!!
Problem solved! I replaced all the spark plugs due to a misfire and then used upper engine cleaner to remove the carbon build-up. During this procedure, I discovered that oil was leaking into the spark plug well. Additionally, upon removing the engine tray, I noticed some oil on the passenger side. As a result, I purchased genuine Subaru valve cover gasket sets and replaced both gaskets and spark plug tube seals.
Hope this helps! 🙂
I replaced my intake and exhaust valves on my Subaru ej253. Word of advice; if it's your first time order a few extra seals. I hammed them in with a 10mm socket as suggested and you're supposed to stop when the ping noise changes tone as it means your new seal has seated. I over-hammered the first couple of exhaust seals and had to re-use old seals; I think oil is getting into the exhaust manifold as I am having some consumption and on one bank the manifold is starting to look oil-soaked. I'm going to have to pull the head and replace the exhaust seals on the one bank. Many many many hours of work (especially on a Subaru) when if I just had a few extra spare seals during my "learning phase" the extra work could have been prevented.
Its a great advice for beginners. Thanks bro...
Excelent video! All symptoms are described.
Glad to hear from you 😊
I have been looking for this info for a while.
Your information is 100 right.
Thanks a lot for you.
I have a 97 ek hatch, and I have the blue smoke when first starting up symptoms, which goes away after a minute. Never shows up again after wards unless I let it sit for 8 hrs plus. Just bought some valve seals and about to replace them.
pcv valve clogged?
@robertswift6101 maybe, but I have a skunk2 manifold so it's not connected. It's a k24a
As you said oil is sucked through during high vacuum. Can you adjust the PCV valve to stay more open to mitigate the problem in the meantime?
PCV is spring loaded for most NA engines...so adjusting is not an option... could just bypass the valve but that can cause too much vacuum inside the crank case...which for most cases is not advisable.
Nice work. Very good information and thanks in advance.
May I ask, do you think stop leak products can stop oil leak in the valve seals and the head cover gasket? I have minor oil loss in my car's engine. No drip but I see oil stains as if sprayed over the body parts (as if sweat). I use lpg as we all know it wears out the valve seals earlier than petrol or gasoline engines. So what do you think about this?
I surely know and am aware of it that even if it works, it is a temporary solution. So does it worth using these products? (I can find Liqui Moly which I surely trust the company because I use their oils with pleasure).
A black sparkplug tells you your running rich. to mutch oil is brown like a two stroke that burns a fuel oil mixture. Your car does not have to burn mutch oil it can be a small amount because huge oil consumption happens over a longer amount of time not in an instant. Remember oil lubricates and the seals have to be worn over a longer amount of time before oil passes trough in to the cilinders. You could also have sticky oil rings normally they come out due to pressure but carbon can stick them in place over time. Oil gets passed the rings and the car burns oil. Replacing can help but only gives a 20% difference overall. Depending on how mutch you like your car it could cost between 400-6000 or more dollars to solve this problem. ( some engines need both sides done V6 V8 V10 and so on) plus doing it wrong can cost you a new engine.
Great information but I have a question....
What happens if oil intrudes at the bottom of the valve stem seal where it sits on the valve guide? Are the valve stem seals also sealed inside or is it just on top?
Its actually a single point sealing. Both on stem and head. The seal is pushed inside the port just like the transmission axle seal. The stem acts similar to the axle. Oil wont leak pass the seal body. Its the stem part which moves n always cause the wear and leak just like the axle seal.
@@autoinfogroup1629 I'm currently doing valve seals on my 85 Supra 5mge engine. One of my valve seals won't go flush on the valve guide, it probably has a 1 mm Gap from the guide...."if that
The valve stem seal does grab onto the stem pretty well, the only problem is that it just doesn't sit flush on the guide.... I guess I have nothing to worry about then.
Thank you for your info!
i have a kia rio 5 whose timing belt got wearied out. at the cause of that the valves got burnt. it was changed and this this the valves got broken. now my car smoke and stops whiles driving. i understand the Engine head got affected when the valve got broken. can this cause the current problem am facing. if so please what should i do
this can also be a head valve timing issue....ie timing error. Or there could be compression leaks....
Can this cause misfire on 1 cylinder? Trying to diagnose after replacing ignition and fuel injectors car stick has misfire and has always consumed excessive oip
valve seals wont cause misfires....if the leak is too high there might be some engine hiccups, white smoke on morning starts and you can see a lot of greasy oil texture at spark plugs tips.
Thanks for your reply.. I did have this problem as well. When I first started the car a puff of white smoke would come out or if I revved the engine above 3500 rpm it would do the same. I noticed the car would randomly hiccup every now and then until one day I was driving down the interstate and lost tons of power and had vibration. Very similar to when coil packs or ignition malfunctions. Tried to replace the known causes for misfire and just didn't help. Maybe burned valves? Code says p0300 and p0302
@@krustdogg131did you fix it ? What was the issue ?
Yes it can cause a car to misfire @@autoinfogroup1629
How to differentiate between piston rings and valve stem seals?
If you have bad piston rings you will have little to no compression in that cylinder. Compression check on all cylinders will tell ya
Bad pistons the car will smoke bad all the time if it's just the valve seals the smoke will happen after long idle or on start up then go away.
I did it on an 03 lancer es and now it wont start. Spark plugs were changed 15k miles ago but the car was driven with bad valve cover seals..
I have a 07 grand marquis and it’s burning oil pretty heavily. It doesn’t run like low compression but idk.
Does this cause misfire?
Yes it can idk why no one responded to you but yes after a period of time your spark plug can gunk up and become useless due to not being able to create spark to ignite
Good work
I’m having blueish smoke on my car but only when I let it on idle for about 10 mins. No smoke on cold start and no smoke on idle as well…
If the car has an egr valve, do check if its stuck open partially. If the valves seals are busted mostly the car would spit out white smoke in cold start for sure.
@@autoinfogroup1629 I just replaced the PCV and the smoke is gone. Thanks for this video tho 👍🏻
@@CV36wllmn Please, what do you mean by PCV?
@@okolifranklin2111 I know this reply probably won't matter PCV = Positive Crankcase Ventilation 🇺🇸 1st 4ever
Yes Positive crankcase ventilation. Its a valve that passes gases which is leaked from piston rings to crankcase. This gases are fed to intake side so its been inhaled by the engine itself and burned off reducing emissions and keeping crank case pressure optimum.
I have mercedes clk 320 wen i accelerate its smoke elot and some time in smoke elot on ideling and sometimes no any help
Smoke from exhaust can from different reasons ...was that black or white or bluish kinda smoke?
It can cause misfire, due to oil being burned off by the spark plug, that’ll cause pre-mature wear on the spark plug, it’ll last only like a day or sometimes a week before it’s all clogged up and black
Mine just smokes in the morning and then never again throughout the day! Burning oil smell... 2006 freelander 1 td4
I have oil on top of my cylinders on top on my spark plugs inside the intake manifold would that be a bad pvc value someone put diesel in my car na it’s gas been happening ever since will idle but dies when u shift into gear
No it would be from these seals. Or piston rings
My dodge caravan smoke only when you park it and idle for about 5 or 10 minutes. But not during start up. Would that still be leaking valve seals? It’s white but have bluish tint.
If there's a problem in seals, mostly, you'll see smoke at the starting and goes off after some time and also at high revs.
You have some of the symptoms of bad valve seals.
My golf 4 drinks pretty much oil and there is some white and blue smoke. Could it be this or mayby bad piston rings?
If it shows blue smoke at start up, and if after you descend a long hill and then go after the stop sign at the bottom of the hill, and you have a blue cloud following you for a little while, it's valve seals.
Excellent video. ❤❤❤
Glad to hear from you mate 😊
I have a weird issue. When I drive and stop and go at a red light or stop sign I have zero smoke. No smoke on cold starts, but smoke only shows when I let it idle for 10-15 mins. I get a big puff on takeoff, then it clears up and goes back to nothing. That doesn't sound like valve seals or piston rings.
Did you figure it out, mines is doing the same, only every now and the puff of blue smoke, not at start up typically when driving and sometimes when at a stop then accelerate puff of blue smoke, you figure it out let me know. Cheers
@@jayzon31 Nope I thought it was the spark plug tube seals but I fixed those and still get the smoke after a long idle. Everyone says piston rings would have it smoking all the time and valve stem seals would smoke on startup. I'm not replacing valve seals on a 17 year old car, so I added a bottle of Rislone ring seal treatment and I'm gonna see what that does. Basically as long I don't let it idle for over 10 mins, I'll never see any smoke.
@@Jedi_Luke Let us know how the seal treatment goes...
@@Raymo2u Will do. I added it 2 days ago and it's still smoking, so I'm gonna put some miles on it and see if it changes. I did some research online and it says I might have bad O2 sensors, because that will also cause this odd smoking only after long idle issue.
Provavelmente retentores de válvula , olha também a membrana do suspiro do motor
My civic 2004 gives blue smoke above 2500 rpm. It’s fine on cold start and no smoke on idle after 15 to 20mins.
Is it piston rings or valve seals?
Oil rings
Imma replace the valve seals in my z31 if this doesn’t solve the problem I’m parting out the car
haven't mentioned the problem!!!
Thanks 👌🏻
Very nice
❤
My diesel car morning time white smoke heavy ..after heating no problem.
Do check the egr and glow plugs
@@autoinfogroup1629 glow plugs good
If you smell pungent diesel smell then its the egr at fault. Or if its burnt oil smell could be anything from head gasket, valve seals, cylinder cracks etc...
@@autoinfogroup1629 oil burnt means oil will reduce . But no oil reduced .... Egr cleaning enough? Egr gives black or white smoke
Egr when cold start, gives white smoke and when warm pushes out black smoke.
How,can i leave a mile of blinding smoke from my car on purpose just to fk with people?
I get white smoke when the ac is on ...
Did you fix it
@@youssefzaiter722 yea i used a thicker oil

Personally I don’t like this style of video. Anyone making RUclips with computer generated voices need to be banned
Hey there mate, It's a piece of information not some entertainment. Even though it's a generated one people gets it. That's what we need.
@@autoinfogroup1629 shame as RUclips is for entertainment so your on the wrong platform
Yeah, I hate this type of video.
Personally what can you offer ?
Get out your wallet for this fix.
Or look up how to do it yourself on RUclips lol literally everything is easy to fix on a car you don’t even need many special tools. Takes 7 tools to rip my entire engine out
I’m sorry I can’t this video seriously with Ridiculous A.I Voice you have Narrating it, if you going to go through all of the trouble of making the video it really seems Lazy to use the A.I voice and does not lend to the credibility of the information you’re trying to convey.. try to do something better seriously..
Apologies my friend 😐
