I bought replacement valve cover for 08 Yukon. Didnt smoke but was oily around the outside of the pcv. I took the original valve cover and drilled extra holes in the baffle and cleaned the pcv with brake cleaner. Return ed the new valve cover. Easy fix and no need to spend 70+ dollars on new valve cover.
Me too! Just drill a few extra holes at the lowest part of the baffle/ chamber. Clean the hell out of it with brake clean and compressed air to get out all of the particles
Smh..that us some B.S they are doing these days...all of that just to change a part that USED to cost about $5.00 ! The auto makers are really sticking it to us with all this "new s***" ! Thanks for the video bro.
no there is NO part anymore. There is no valve to change, its just an orifice. My 03 has a grommet like the old ones, but the PCV insert is empty, just a little hole. I researched it and that was one of the things GM did to reduce oil consumption.
I just purchased a re-manufactured engine for a Silverado 1500 4.8 and the PCV valve is also part of the valve cover, on the original engine it would pull out. I am going to pay attention when I have to replace the PCV valve that I get a cover that is like the original.
+Dan Hillman no didn't try that replaced mainly due to the cover leaking anyways ha ha probably could have tried that and just replacing the gasket but oh well ended up mainly being bad fuel thankfully didn't wreck my fuel pump ha ha I put lucas fuel system cleaner in and first treatment the problem stopped.
Thank God they changed this bullshit design for the 2014 and newer 5.3's! We have a simple little $6 pcv valve that screws in down by the throttle body.
Did you try to spray it with a bit of carb cleaner first? I don't see any problem doing this as with a running, warm engine it would evaporate quickly. I'm having similar issues. That's what I'm going to do. It can't be worn out, I'd think. Sticky or gunked up maybe, but not worn out.
Update. After a week with new valve cover the smoking has stopped. Still can’t believe I was dealing with embarrassing smoking for 2 years thinking the problem was valve seals. Anyone else experience same issue just try cleaning out first or the hell with it and replace valve cover.
Josh Turner ya smoke for sure and a some oil was going by each oil change but my exhaust pipe had black residue on it which I assume is oil burning lol I miss that truck still I have a 2014 ram 1500 now....it's ok not worth the money though that they charged me.
I have an 06 with white smoke on start up & has oil in the throttlebody..i disconected the pcv valve hose from valve cover..will replacing the valve cover will get rid of smoke and oil in the throttlebody
If you have oil in the throttle body you may have bigger issues to address then a PCV valve , sounds like your getting some hefty blow by could point to worn out piston rings but thats just my thoughts I'm no mechanic so can't say for sure.
Does anyone bother to check if the pcv valve is faulty. I saw another video where a guy replaced the pcv valve it just had a small hole at the bottom of the body and a tube to secure the hose it was not blocked and he replaced it anyway. I feel in this case if the pcv valve is part of the valve cover the pcv valve would be similar or serviceable.
My 2007 Silverado 5.3 has 295k and started smoking around. 275k. Does not burn oil but Ive change oil every 2k and add Lucas oil stabilized. It has minimized cold start smoke but not completely. I cleaned out valve cover which seemed to work for a week or so. Purchased $82 dorman valve cover and smoking has stopped for now. Does anyone know If Pcv is passive on these valve covers?
I have 5.3 on my avalanche it was in bad condition when I'm first got smoking and all the works so what I did was after changing every gasket known to man is run a qrt of marvel mystery oil in with a new filter and ran it for good 2k miles and changed the oil and all the sludge cleared up improved my oil pressure and carbon build up was able to haul my explorer up the mountains with no problem and has over 240k know I just did the same with my 5.2 jeep and in just a couple miles it has increased hp oil pressure and should clean all the valves
Did it blow white smoke or black smoke? My 2010 blows a puff of white smoke at start up then runs fine. Other than the smoke, the truck runs fine and won't smoke until it cools down and I crank it up.
Blane Grinsted ya more or less but this didn't 100% solve that issue for me just the leaking oil issue down side of the block in my case I assume I was getting blow by so damaged piston rings or the heads had some damage in 1 or more cylinders in my case wasn't losing to much oil yet but had black oily sut build up on my exhaust tip
That's bad valve seal(s) letting oil past your valves when they open. When you turn it off, if the engine stops on a cylinder that has a leaky seal, it will let oil into the cylinder that will sit there until you turn it on again, thus the puff of smoke.
The GM intake manifold gaskets on these trucks are trash. I had my intake manifold drip 4 ounces of oil out of it when I removed it because I kept getting lean bank 1 & 2 trouble codes. When there's a significant vacuum leak on these trucks, it just sucks oil out of that "fake" PCV featured in this video. Removing those gaskets revealed a super cheap and flimsy plastic cutout gasket with thin green gasket material that was leaking on 5 out of the 8 cylinders. Replaced with Fel-Pro gaskets and instantly fixed my issues. 2010 silverado 5.3, btw.
Having same issue 2011 Chevy Silverado blue cloud of smoke at start and throughout the day at times not much only last few sec then clears up could this possibly be my issue?
Comarade Lee/ so been a day or so since changed out pcv valve cover to updated cover so far so good man no smoke thanks for info great video just saved me 500$ had a mechanic tell me it was my valve seals and that’s what he would be charging me thanks again!!
@@austinchandler2663 I decided I have too much going on to change it out and that it’s not bad enough to do it. Working on my new house is full time job. My truck is ok and doesn’t seem to need it if I keep the rpm’s not so high. If I drive it normal then the lifter doesn’t tick and no smoke at startup.
I think you can clean the pvc with carb cleaner,,, I know the older style 80's 90's with rubber grommet we cleaned the all the time and reinstalled ,, I am going to spray carb cleaner in the pvc on the truck,,,and see if it helps,,, happens is shilack? Builds up in the pvc causing it not to move and close off the vacuum from your motor,,,that's why it sucks the oil into the intake and makes motor smoke,,all the same stuff shilack? Clogs the little drain holes between the baffles drain holes on the bottom of the valve cover ,,, it a combination of serveral things,,, try this,,,unplug the pvc hose where it goes into the valve cover,,, stick a bolt or something in the hose and put a hose clamp on it so you don't loose vacuum in you intake,,,drive the truck 20 30 minutes or to work just to burn the oil that's already in the intake,,, cut the truck off let it sit and cool off ,,, or over night,, the next time you crank see if it smokes ,if it does not smoke you know it's your pvc,,,if it still smokes as before with no change then it's something else,,,,,,the pvc is on the motor to create a vacuum inside the motor so it does not leak oil is all it does,,,also low vacuum such as a cracked hose on the pvc will make your traction control light come on and off on the dash if anyone is having that issue
The pcv valve in this truck. It is not part of the valve cover. The pcv valve is pressed into the cover. It is removable with a bolt extractor. New one pops into place with a socket and hammer. Guess you have a new valve cover now though lol.
Mike LaRocque; I was curious about this..can find nothing about the procedure you explain. I see a genuine gm replacement valve on rockauto but I cannot tell if it's an actual pcv or just a fitting. I'm assuming you have done this before and would be grateful if you could elaborate on the subject a bit more.
Even if the PCV valve is replaceable, he likely would've needed to change that valve cover out anyway to the updated one. Hopefully he replaced it with the new design and not one of the original design.
Hey what were the problems you were having? I have an 09 and it smokes when I start it up after its sat for a few hours or so. Did some research and looks like this is what I need to do. Just curious what your problems were.
Luke Westrick I mostly changed it cause I had oil leaking down the side of my block from that cover, along with minor oil consumption most likely from the leaking and I had some rough starting issues turned out to be bad gas though, if yours is smoking like from the engine bay round that area see if your leaking oil or something leaking causing the smoke.
Ya most my issues were solved obviously still the normal little bit of smoke on every vehicle specially on cold days more then anything turned out to only be part of my problems other half was bad gas causing the rough start so some Lucas gas additive thrown in drove around for 30 min went on the highway next start was perfect, I do get a weird chirp/grind noise that happens on cold days first start like 5 seconds after it starts coming from the steering pump rack and pinion area the pump is brand new flushed the system even 2 times so not certain what's going on there everything on the front end is brand new now except my water pump ha ha
I have an 06 yukon..it has oil in the throttlebody i took it apar and cleaned it..disconected the pcv valve hose and looks like its the valve cover pvc..any body with the same problem and has smoke on start up
I’m running Lean bank 1 and bank 2. I replaced my MAF ,O 2’s , fuel pressure sensor . I’m stumped. Could it be this pcv valve ??? I’m sick of trying to figure this out
How many kms on the truck though? I've been told instead of doing what I did with my issues and replacement of pcv valve I could have just used carb cleaner or something to clean and possibly free up the stuck valve first, again can't say for sure if it'll help cause I can't remember much on the engine codes I may have had, I replaced mine due to leaks around the cover along with poor starting and engine noise, in the end I'm pretty certain I should have replaced water pump and fuel pump, fuel pump for the rough starting sometimes only turning over but not firing up, and water pump for the loud squeal from the front after I replaced everything else like tensioners idle pulley, alternator, power steering pump x3 , should have figured something was putting pressure on the system blowing pump after pump, but swapped the steering pump last time under warranty, then traded the truck in unfortunately....wish I still had it, but I'm certain it had many other demons to deal with despite being a beautiful truck in amazing shape.
Maybe....I'm not sure I wasn't losing much oil a bit buy not much and don't believe I did anymore after check your tail pipes for black residue with a oily texture means your more than likely burning oil possibly bad seals and or piston rings not in good standing check spark plugs see if there's oil build up on those as well
My truck had about 137,500kms when I traded it in and I could tell it was burning a bit of oil by the state of my tail pipe as far as trading in my truck liked to play fix this today that other thing breaks tomorrow and that started getting old real fast....and annoying/expensive I loved the truck and kinda miss it though, this 2014 Ram 1500 sport I have now is a not bad truck more power/torque for sure but the rear end in this truck perhaps all rams is kinda crap in my opinion my Silverado had the posi trac style limited slip so when traction and stability were shut off both rear wheels would spin never had to fight that truck for control ha ha this Ram last bit of winter with it not impressed with its handling in snow, Silverado was awesome in the snow with the goodyear duratracs, so I think its safe to assume I will be going back to having a chev or gm when the time comes with this truck, its nice looking and all great features, just prefer my old truck ha ha
Eric Estrada not sure if I had to guess likely just when they started the body style of my truck really annoying but that's what they want the harder it is for us the more likely people start going to dealers and shops for work ha ha
+Marcos Rocha I recently while driving home from a town 30 min from me realized I had like no power and the engine was way louder than normal sounded like it was off at the headers, and then just as I looked down my check engine light pops on and of course my scanners are both at home ha ha, oil pressure dropped right down to the quarter mark couple times under that, first thoughts shut truck off checked to see if I still had oil still right full, but kinda dark then remembered I was due for an oil change like right around that km mark as it turned out my filter was either plugged or collapsed motomaster filter made by frame same shitty cardboard top an bottom piece the centers the replaced with metal, supposedly fixing the collapsing issues....but either way no harm done fortunately I limped it home, did the oil change the next day I'm cheap and don't learn so went with motomaster oil and filter again....so far so good 2,500kms into the oil change still good oil pressure for now....ha ha
Well thing is I replaced it and oil gets low and I get check engine error code p0174, I can't figure it out . Should have left old one on, and avoided a head ache
+Marcos Rocha ya I had that exact same code when I got home went away on its own after oil and filter change also buy some sensor cleaner and clean your maf sensor mine had some dirt on it can cause that code either that or your maf sensor is faulty and needs replacing or a vacuum leak some place but mine resolved after cleaning the sensor and the oil and filter everything happened all at once lol
All this does is fixes the oil consumption issue. It has nothing to do with the pcv valve itself. The pcv valve is working on both circumstances. It’s just that with the old design the oil gets sucked into the intake and burned in the combustion chamber. The new design has a baffle so that the oil cannot get sucked into the combustion chamber. At least very very little oil gets into the combustion chamber. You could essentially do the same thing with an oil catch can set up. The only downside to that would be that you would have to periodically dump the caught oil back into the motor. But it would stop the oil from being consumed inside the combustion chamber.
Ya I have a catch can on my 2013 silverado now it catches vapors mostly effective in winter , with cold starts and condensation not ever much oil in mine and even if there was dumping it back in the engine would be stupid , as its generally mixed in with the condensation so it would be oil and water so ya.
@@alphasaiyan5760 I still need to drop my oil pan and replace my oil pickup tube/o ring and the pan gasket low oil pressure issues that weren't solved by the usual oil pressure sensor
@@WestWire I did this today on my 2013 tahoe ltz. I changed the valve cover on the driver side. The pcv valve in the old cover was clogged up and causing me quite a bit of oil consumption. So I got a new one and changed it out. I’m changing the oil and so I’ll see if it fixes the oil consumption issue.
@@WestWire I had an oil catch can on my 04 gto. It helped a lot because the valve cover is a lot like this one. They could’ve made the pcv changeable if they really wanted to. Just another way for gm to make money off of people…
thomas martin not really on this year it's all part of the cover unlike older styles where you could just remove it from the cover then you could clean it more so, I mean ya you could try but since it doesn't come out it wouldn't get cleaned well enough but I changed the whole assembly partially cause the seal was gone and it was leaking out the side of the cover ha ha.
thomas martin yes but that motor had other demons water pump was going and couple bad piston rings cause rear 2 spark plugs often were soaked in oil either that or some defects in the ports but it's more likely it was bad rings on the pistons not to mention fuel pump was starting to go ha ha loved that beautiful truck but every time I fixed 1 thing and 1 or 2 more issues came up.
They want it harder and harder for DIY guys to do just that....and be forced to take things in....if I replace certain parts on my 2017 Nissan Altima part will likely not work till the dealer reflashes the CPU....lol

I'm going to replace but with a vc that has a pcv valve
People replace it because the OEM design was shit and the aftermarket ones are designed better

Is the pcv supposed to be open allowing air both ways when it off

The PCV valve is a one way check valve. It only lets the crankcase gases flow in one direction.

Pretty sure they only have it on that side, also that was the side leaking as well so seen no reason to ever do the other side

Eric Estrada not sure if I had to guess likely just when they started the body style of my truck really annoying but that's what they want the harder it is for us the more likely people start going to dealers and shops for work ha ha
Mine is a 2004 5.3 and the pcv is just like the video.
Crazy8 wow guess they were only a smaller thing before the 2000's ha ha
I have a 2002 and has an interchangeable pcv valve. So they probably changed this in 03?
My 03 has an interchangeable pcv valve
Ok question, I just replaced mine. And it seems my oil pressure is a bit low did you get this?
try changing your oil filter if your close to oil change fixed it for me did whole oil change anyways lol
I'll try that
+Marcos Rocha I recently while driving home from a town 30 min from me realized I had like no power and the engine was way louder than normal sounded like it was off at the headers, and then just as I looked down my check engine light pops on and of course my scanners are both at home ha ha, oil pressure dropped right down to the quarter mark couple times under that, first thoughts shut truck off checked to see if I still had oil still right full, but kinda dark then remembered I was due for an oil change like right around that km mark as it turned out my filter was either plugged or collapsed motomaster filter made by frame same shitty cardboard top an bottom piece the centers the replaced with metal, supposedly fixing the collapsing issues....but either way no harm done fortunately I limped it home, did the oil change the next day I'm cheap and don't learn so went with motomaster oil and filter again....so far so good 2,500kms into the oil change still good oil pressure for now....ha ha
Well thing is I replaced it and oil gets low and I get check engine error code p0174, I can't figure it out . Should have left old one on, and avoided a head ache
+Marcos Rocha ya I had that exact same code when I got home went away on its own after oil and filter change also buy some sensor cleaner and clean your maf sensor mine had some dirt on it can cause that code either that or your maf sensor is faulty and needs replacing or a vacuum leak some place but mine resolved after cleaning the sensor and the oil and filter everything happened all at once lol
Does it create some moisture in oil?
Dont honestly remember
Getting some in mine. Have heard it will do that
@@chrissimmonds4898 ya most likely even with all its issues I miss that truck pretty sure fuel pump was going to ha ha
Mine too lol. 200k going down hill fast
All this does is fixes the oil consumption issue. It has nothing to do with the pcv valve itself. The pcv valve is working on both circumstances. It’s just that with the old design the oil gets sucked into the intake and burned in the combustion chamber. The new design has a baffle so that the oil cannot get sucked into the combustion chamber. At least very very little oil gets into the combustion chamber. You could essentially do the same thing with an oil catch can set up. The only downside to that would be that you would have to periodically dump the caught oil back into the motor. But it would stop the oil from being consumed inside the combustion chamber.
Ya I have a catch can on my 2013 silverado now it catches vapors mostly effective in winter , with cold starts and condensation not ever much oil in mine and even if there was dumping it back in the engine would be stupid , as its generally mixed in with the condensation so it would be oil and water so ya.
@@WestWire yeah they work wonders. And yeah why would anyone dump obvious oil mixed with water back into their engine. If it was just oil yeah lol
@@alphasaiyan5760 I still need to drop my oil pan and replace my oil pickup tube/o ring and the pan gasket low oil pressure issues that weren't solved by the usual oil pressure sensor
@@WestWire I did this today on my 2013 tahoe ltz. I changed the valve cover on the driver side. The pcv valve in the old cover was clogged up and causing me quite a bit of oil consumption. So I got a new one and changed it out. I’m changing the oil and so I’ll see if it fixes the oil consumption issue.
@@WestWire I had an oil catch can on my 04 gto. It helped a lot because the valve cover is a lot like this one. They could’ve made the pcv changeable if they really wanted to. Just another way for gm to make money off of people…
$67 pcv per cover..on amazon...
You can clean it
thomas martin not really on this year it's all part of the cover unlike older styles where you could just remove it from the cover then you could clean it more so, I mean ya you could try but since it doesn't come out it wouldn't get cleaned well enough but I changed the whole assembly partially cause the seal was gone and it was leaking out the side of the cover ha ha.
WestWire did it stop your oil leak
thomas martin yes but that motor had other demons water pump was going and couple bad piston rings cause rear 2 spark plugs often were soaked in oil either that or some defects in the ports but it's more likely it was bad rings on the pistons not to mention fuel pump was starting to go ha ha loved that beautiful truck but every time I fixed 1 thing and 1 or 2 more issues came up.
Part no. Please
Couldn't tell you thats like 4 years ago now sorry
WestWire
Thanks 🌹
What a rip off design...…. All about ripping off the car owners.
They want it harder and harder for DIY guys to do just that....and be forced to take things in....if I replace certain parts on my 2017 Nissan Altima part will likely not work till the dealer reflashes the CPU....lol
What a B.S. design.
Just another reason I’ll never buy gm.
You should know there is no PCV valve in there. its just an orifice
Nice video, next time be professional and spit your dip out before you start talking.
I don't chew thank you very much, I had a cold during this video.
@@WestWire Sorry about that.
@@rubbermaidable lol no worries
