this description of poor valve stem seals & piston rings is pretty spot-on!! well done & yes I'm experiencing such an issue now with my mini :(

[@Hewhoisstoned420]

Thank you so much. I almost paid $6000 for a rebuild because I thought it was piston rings but I think you just saved me a lot of money. I’m going to change my seals and wish me luck!

Yes, you answered my question in one video. So it's the valve stem seals I need to replace. I've searched forums far and wide and never got a conclusive answer. Thanks much 👍

[@flexjay87]

A lot of times, you can have worn rings and valve seals at the same time, because the engine has a lot of miles on it.

[@luis241661]

awesome video! i want to add that if you have blue smoke on deceleration (letting off the gas pedal) it’s another sign your valve seals or guides are worn. letting off throttle causes a vacuum on the intake side, drawing oil through worn seals. also check your spark plugs! worn valve guides will usually accumulate oil on only one side of spark plugs. if spark plugs are entirely covered in oil, this indicates piston rings. that’s all i know on blue smoke, hope this helps someone.

Pcv and breather system is a very common reason for burning oil be sure to check that before tearing apart ur engine for no reason 😊

[@jasonmckenzie9936]

Thank you very much for this video. I'm currently in school for mechanics and your videos are very very helpful. Thanks bro! JESUS bless.

[@jrattackk]

I went for automotive tech but it was a joke man. 30 mins of “class time” where we we’re actually educated and the other 6.5 hrs was shop work where the instructors would only come out if they had a side job they were making money off of while exploiting the student’s free (to the instructors) labor and eagerness to work on something. I only stayed long enough to get certified to use a multi meter. I learned more in this video than I did spending 1500$ on one semester of school lol all it’s good for is the paper that says you sat through it all or as they call it “certification”. My truck actually went out on me coming home from school so obviously I just had it towed to the school. I did enough deducting to narrow it down to either blown head gasket or intake manifold gasket, but when I came to the instructors for some input or directions, all they said was “check the spark plugs” no context or anything but I was way past that and they wouldn’t even come look at it or anything, so I ended up having to drop out… “I had to drop out of automotive school because my truck broke down” sounds really fucking dumb without context lol

[@jasonmckenzie9936]

@jrattackk I understand. The instructor here actually does try to educate and make sure we know what we are doing, he's always busy helping and I can respect it enough to stick around. Seems like some instructors or vested in their students ans others, well, not so much.

[@iviaverick52]

what if the smoke is intermittent? sometimes it smokes while idling, sometimes it doesn't. Sometimes it smokes under acceleration, sometimes it doesnt.

[@70MUSTANGMAN]

Thank you. I have been trying to figure out why I get more smoke when I floor it. My engine was rebuilt 2 years ago. I’m thinking now that he used old pistons and rings rather than replacing them.

[@declansgamereview6523]

Thank you so much for this. For the past 2 years I thought I had bad rings and thought its odd since the engine was redone 3 years back but being a Toyota I just assumed rings. Anyway I am now contemplating on whether to do this myself or not

[@rosscarstories]

Thanks for the videos, perfect as always, i suspect bad valve seals in my N42 motor and now i have the confirm of that, only smokes blue when the car sits for a while and I start the engine

[@TheSksexton]

Nice tip. Likely just saved me a lot of trouble as I'm about to address this problem in my 2000 chevy.

[@mike479]

Very good explanation how to tell the difference. I believe my car only has bad valve seals. I would rather repair that than have to do the oil rings! It’s a DOHC Saturn, of course it’s valve seals.

[@edubwes]

Thank you. Your video helped me diagnose my oil burning problem. I was afraid it was the piston rings but the car stops burning oil/ blowing white smoke after about 3-4 minutes of driving.

Nice video and explanation. I think my valve seals are bad, my car really is using a lot of oil. When i start the car in the mornings, the idle is rough for a few minutes and i believe there is smoke (i need to look more closely to check). My question is, is replacing the valve seals a difficult job?

Thanks. Ya my Acura legend only smokes when it’s idles for a min. But when driving it goes away. I’m in the process of taking it apart now

[@TIMTIM-xm5pr]

You find what is i have the same problem

[@andrewziegler2608]

@@TIMTIM-xm5pr yes, the oil is definitely coming in from the vacuum lines off of the valve covers not just the PCV but the other vacuum lines on the other head. The baffling in the valve cover that is supposed to only allow Blow by gases to pass isn’t working and allowing oil to pass as well. I found oil saturating my air filter, and in the intake tube and in the intake manifold. I installed two catch can reservoirs. One for each valve cover. They fill up after a couple weeks. I probably should just replace the valve covers, if I can find them. My car is 30 years old. I hope this helps

[@Fuzzfdt]

One of the best videos I’ve watched thank you

[@wensis2006]

Thank you! I think you just diagnosed my problem with mine 2008 r55 mini clubman cooper s.. I think it's the seals indeed. Although I burn a liter oil every 400km orso.. That's alot but.. The symptoms are more on the seal side then continually on the cilinder side.

[@JoJanDiezel]

What happened, did you fix the Mini?

[@aleksandarkocovski6939]

What if the car consumes oil but the exhaust smoke is white? My Seat Leon MK2 doesn't have rough rpm but has a small pending rpm at coldstart, after the coldstart goes down (15-20 sec) then idle is good. White smoke comes out even when warm. I don't see any waterleak because it is on same level all the time. I know these EA888 gen 2 engines have issues, but what I experience doesn't match with what I experience. High consumption of oil but white smoke. Waterlevel is good but not oil level. Am I missing out something? Thanks man, your videos are the best!

[@Lastbadie]

Head gasket needs to be replaced

[@DonBMW]

I have a strange situation. I have a 97 BMW M3 that consumes about 1qt per 800 miles. No smoke on start up. No smoke on acceleration or deceleration. Engine runs amazing and revs ultra smooth. I think it may be the CCV (PCV) valve. Thoughts?

Check the ground, the asphalt, the driveway

[@jameswhoolf7875]

Can extremely worn valve seals cause the vehicle to smoke while raising RPM pressure I have a 1990 Honda Civic and it appears not to smoke until hard acceleration I just don't want to be wasting my time repairing one thing when it's another thanks best regards appreciate the video

[@Taylor-jq6rl]

i replaced my piston rings last year payed 6k for it but still smoking its not losing oil i only top up around 50-100ml for every 30k miles i hope its only valve seal issue it sometimes have smoke and sometimes it doesnt

What do you think N52B25 engine when starting cold it doesn't smoke and smell bad only rich fuel mixture smell. When it warms up then it's smoking constantly bad smelling grey smoke and when leaving from the traffic lights it puffs out a blue smoke and the exhaust smells like burning oil real bad. Cylinder 6 spark plug is covered with oil and all the other spark plugs looks ok only two other cylinders had ash deposits on spark plugs. Compression is ok so what do you think CCV or bad piston oil rings?

[@mikejohn0088]

THANKS! That was great information!

[@scottdc2105]

Also if you check the spark plugs and one or two have much more carbon on them than the others thats because the intake valve seals are letting more oil get sucked in.

[@c.anderson3444]

What about blue smoke ONLY under hard acceleration like when passing another vehicle. Car has only 30k miles, but in storage 7yrs, No external leaks, good pvc but consumes oil based on dipstick reading. My guess is hardened seals?

Ok I’m confused, based on my compression test, it’s the valve seals - I did a leak down test and still had no compression after doing dry compression test. 150-150-0-150 compression test readings (cyl. 3 is dead) - it’s burning oil constantly I replaced the pcv - it was faulty from day 1 - I believe it’s what caused the blown valve seals on cyl. 3 from too much oil pressure. (intake manifold was full of oil when I replace the pcv) Engine is 2.0l Cobalt SS Turbo LNF - has 20k kms - prior history of blown valve seals Thoughts?

Approx How much oil can you burn in a 6 cyl if the VALVE STEM SEALS are all bad? Could you burn a 1/2 quart or 3/4 quart of oil in 250 miles if those VALVE STEM SEALS are bad?

[@CHIBA280CRV]

Very informative video thanks 👍👍👍

[@jonwood4403]

What I don't quite understand with these oil consumption issues are if the catch can isn't catching much oil from the PCV and you have no smoke from the exhaust where is all the oil going? I have a Mini R58 N14 engine which has all the classic symptoms of high oil consumption (1 quart per 500 miles or so) but no smoke, little oil in the catch can and no oil leaks so where is it going? If it is going out the exhaust which is the only place that makes any sense why has my catalytic convertor not been destroyed or thrown an error and how do I pass yearly emissions tests? - I give up!!

[@gravityimage5]

Thank you for your detailed analysis. As for valve seals, will it smoke under hard acceleration as well?

[@billbrown5813]

You are right... also (he didn't mention) If the seal is cracked or worst, broke off,,, it will act just like a broke ring. Have to determine the miles, how it was drove.. etc...

How it can be explained that the car burns oil but it doesn't have any leakage or smoke ? What could be the reason? Because once the oil ends in the combustion chamber , through valve seals or piston rings, you should have smoke, right?

Unfortunately this does not apparently cover all scenarios :( . I have a mower that loves to burn oil, but how much it smokes seems to depend on orientation of the mower or where I am in the yard, don't always notice clouds, usually they aren't there right when it starts up, but they seem intermittent... I guess it must be burning it all the time though because I throw half a quart in and sand blast the spark plug for that cylinder every single time I mow. Guess I need to visually inspect those valve seals first, that's the low hanging fruit.
