2 years ago I bought a used 2001 Suburban w/ 5.3L engine LM7 (cast iron block), 290k miles, runs great [This is pre-AFM]. I Use it in winters for a 4k mile trip. First winter it guzzled one quart of oil every 800-900 miles. Fixed all external leaks but still gulped a quart every 800-900 miles. Once back home I installed this valve cover. It killed that oil consumption problem DEAD! The next winter I changed the oil immediately prior to the annual 4k mile trip. Made the trip and now back home using it for my daily errand car. Haven't had to add any oil !! Looks like it'll make it to the 7500 mile oil change interval, or close to it. AFM or pre-AFM, these engines were prone to gulp major oil by ingestion through the PCV valve delivering it right into the intake manifold. This valve cover will kill that mechanism of oil consumption.
Great videos! 220k on our 2007 Silverado 5.3 . It has a P0300 mostly on cylinder 3. I'm used to PCV valves being replaceable but since this valve cover hasn't been updated it may be a smart move. I've already popped the cover off to check for a stuck lifter but it's fine. The inside valve cover/pcv hole was covered black
J P Im getting the same code but my suburban is misfiring I doing this tomarrow to my 2007 suburban. Did the same to my 06 Silverado
Who’s bright idea was it to have the PCV valve built into the valve cover itself? That seems a bit unnecessary. 🤔
One little tid bit of info that you probably did but didn't mention...... Use anti seize on your spark plug. Good video
Yes! That's always great idea.
Thanks, I just did this in about an hr, hopefully its better now :)
onecutmedia running better?
Max Gee not really. Still using oil. Maybe not as much is all 🤷♂️
If it's not, it could be the oil pan. www.agcoauto.com/content/news/p2_articleid/344
Where can I find all the torque specifications for that motor
Great video, Chris. Saved a a bunch of money being able to DIY. Thank you!
I hope this helps someone it didn’t help oil consumption on my but I’m turning off DOD soon
Does this problem also include 2011 escalade?
Chris, Great Video very informative. I have a 2017 GMC Sierra. The low oil level light has been coming on frequently and oil consumption seems excessive. Would the fix for the 2nd generation be the same for my 3rd generation (2017) . Should I start by checking the #7 spark plug?
Yours is supposed to have the updated system already , with new piston ring design , piston skirt baffles , the valve cover and the low oil light ... The AFM system seems to be the main cause from what I am finding out .. Get a programmer and turn it off is the only option ive seen beside sea foaming the engine to clear the carbon off the pistons, and hopefully the rings .
Absolutely Great Video!! Thank goodness for you guys who post these vids. You save the rest of us a lot of money!
Will this issue cause oil and fouling on #6
Recently bought a 2010 sierra with a 5.3 I've been using about a quart every thousand miles or so. One thing I've noticed is I have to let the engine sit for a long time to get an accurate oil level using the dip stick. The engine sounds/runs good. I'm wondering if this will fix my oil consuption problem
So this helps stop the oil leak from my number 7 spark plug??
230k miles on my 07.5 Sierra 5.3 and I'm now planning on doing this
I’m in the same boat and same mileage on my 2013 Silverado.
My check engine light is on and cylinder one is misfiring and took the spark plug out and it was covered in oil. Will this correct the problem of oil on my spark plug?
Thanks for your help and the video
Absolutely.
So did it work? Did oil consumption issue get resolved?
Did not work for 2008 gmc Sierra 1500 pcv valve connection is different im trying to see if i can swap the hose out from Differant model
Too bad about Chevy. Bought new engine at 100k miles because it went on limp mode from all the oil problems. Disabled AFM on the new one and hasn't had a problem so far, 65k miles and no oil consumption. Just hoping it doesn't become a money pit.
I have a 2009 impala ss. Same issue, cylinder 1 keep fouling out. Will this fix?
I have a 2001 the value is in the same place as your new cover and I still burn oil why
good video that's really helpful 💡👍
Lisa Hernandez Thanks! Make sure to subscribe!
So this only needs to be done on the drivers side?
Yes. The drivers side is the side with the PCV valve.
awesome video!! Thanks for posting it!
Great video man. Very helpful and easy to watch.
Years - for this application??
Hi .good video . you didn't need to change gasket thought
Which Gasket are you talking about?
Pretty quick and very detailed. Thanks!
Hi CHRIS ARNAU - does this fit 2009 Silverado with 5.3 ?
Yes sir. amzn.to/2C5MIhd
will this fix work on a 2008 Denali 6.2?
Would oil consumption be a reason my 14’ Sierra 1500 has a code saying the cats have gone bad?
Possible. Oil has zinc and phosphorus which coat the cats cells and then the rear O2 sensors see that. Many Armadas and Infinitis that burn oil get codes for cats. Many replace them with pipes and O2 simulators.
Thanks
Why do GM v8 seem to have so many issues,years ago they ran and ran and ran???
cause the bastards built the damn pvc valve into the damn valve cover so it is a major job for most and cost a fortune to have done.. when in reality this should be a easy fix for anyone for about 5 bucks if the damn pcv would just unplug like it should instead of being MADE into the valve cover.
Did you just change the #7 spark plug? Would it make sense to change all 4 on that side?
Brad Stanley you can if you want change all 4. Or for that matter all 8 on the vehicle. I just don’t change them unless they have a problem. No sense in changing a perfectly good part. Now if the other plugs are skipping or fouled. Change them for sure.
Chris Arnau thank you! I have 80k on my 2011 suburban... consumes oil. I’ve always used Mobil 1 but not sure of any other issues/damage... what would you do?
Personally I would change them all since they are only good for 100,00 and it is pretty close. But it isn't necessary unless they are skipping. But if it were my personal truck I would go ahead and do it.
typically this issue was diagnosed on #1 & #7 plug was changed because it was
contaminated with oil.
I have a 2010 GMC Sierra 5.3 I have installed this new "updated" valve cover it has done nothing at all oil still gets sucked through the pcv into the manifold.
Did u ever fix ur I updated to and still burning oil
I was thinking about trying this repair, but I've seen alot of people say it didn't work...
2012 Silverado owner, 71000 miles and losing 1 quart of oil for every 1k miles. Heard that this should fix it. Just hate to spend this money and still have an issue.....
azrwilkinson this would definitely be where I start.
Chris Arnau thank you
I have a 2008 Silverado with 245,000 miles on it. Before I got to this mileage I was getting pretty good oil consumption and my truck does not have AFM. I replaced the valve cover with the updated one and I have next to nothing on oil consumption with the current mileage.
Cummins Owner how did you get a 5.3 Silverado without afm?
@@PanchoPistolas45 mine was the last of the 5.3 engine trucks on the lot without the afm. I would say that I lucked out.
Damm im a little scared to do it , but I have to, great video very good explanation thanks
You can do it!
I'll do it man thanks... a local mechanic wants 350 to replace it i need to buy the part, he said he charges for what he knows, and experiencing and the cost of labor seems to me a little too much but I dont know the rates so yeah.
CSSG-1 right?
do a quick check of the rocker arms to see if you have a stuck lifter, just never know.
good work
So this helps stop the leak in your spark plug ?
It stops the PCV from pulling over and fouling out the plug. Yes.
Thanks
How is that Valve cover
no need to install so called updated valve cover or oil catch can just drill a few extra holes in the baffle and enlarge the one by the pcv then clean it
The problem is pull over. Adding extra holes will increase the amount of oil that the PCV pulls over.
@@cdarnau what is pull over the problem is the oil don't drain out of the baffle before it gets to the pcv port
@@shaunnesbit1734 The pull over problem is a mixture between a weak PCV and oil sitting on top of the baffle and getting pulled over. If you drill more holes you're not going to drain any faster. There is a 2in gap for draining. If that's not draining fast enough you have other problems. The problem is the weak PCV pulling oil from the baffle. Regardless of how many holes you put there you are still going to pull oil. Lets say you cut the whole baffle out and shield the PCV so no oil can get pulled. You will still have a weak PCV causing other fuel trim related issues with the vehicle.
What year did they start using the new design? I have a 2013 truck
2007
@@cdarnau so the 2007-2013 has the new design ? Valve cover ?
@@cdarnau the valve cover update ?
Yes, excellent video
Thanks
Thanks for this!
Is this a "known issue", Like could there be a recall or something with it? Seems like there should be.
John Davis Sr yes it is a known issue. Unfortunately there will not be a recall on it because it isn’t a safety issue and it would cost way too much for GM to do this.
what about the 4.3 v6? mine uses a tone of oil! but there is no blue smoke...very strange to me.
My 09 v6 silverado does too. Only have 46k miles on the truck
I have an 05 Silverado and my PCV Valve is on the Valve Cover like apart of it I think? It won't come out/budge. How in the world do I replace it??? I can take the rubber hose off of it easy but the valve itself won't budge out at all. I tried everything, please help.
Replace the valve cover.
@@cdarnau Too expensive. All good. I will just clean it and spray some carb cleaner on it.
I have a 08 Silverado with the 6.0 liter that is using a qt oil every 1000 miles but nobody’ talks bout this motor. Should I change valve cover ?
GM SB 10-06-01-008 covers L94, LZ1, L99, LC9 (this engine 5.3 trucks) LH6, L76, LFA, L92, here is the cheapest newer style cover i found
www.summitracing.com/parts/rnb-264-969
Do you need to do the afm delete when you install new valve cover?
No, Just the valve cover.
Where did you get the new cover
Amazon. Here is the link. amzn.to/2C5MIhd
Cheaper at www.summitracing.com/parts/rnb-264-969
I have an 07 and my new cover comes in tomorrow and I’m gonna replace because I notice excessive oil consumption after driving. What’s your thoughts on the AFM delete or whatever it’s called? Do you not recommend it for any reasons?
You're awesome Chris!
Does the batterie need to be disconected.
Did GM correct the oil consumption problem by 2015 on the 5.3 Sierra or does it need the valve cover repair. Does it only need to driver side or do you replace both sides??
January 2011 is when GM started installing the new valve covers on the 5.3l's. And only the driver side has it since it's the PCV valve.
@Tom Wetz Your truck should have the new style valve cover. January 2011 was when GM made the switch so every 5.3l after Jan. '11 will have the new. If you're having to add a quart of oil every 1,500 miles, you have more problems than just the valve cover unfortunately. :(
@Tom Wetz That is really weird that a 2012 would have the old style. There's even a TSB from GM that states that Jan. '11 was the switchover date.
@Tom Wetz Glad to hear things are getting better! Mine usually runs about 35psi when warm but it's steady. :)
@Tom Wetz that is really weird. keep us updated
What's the part number for the valve cover
juiced78 It’s in the description. I’m away from my computer right now and my phone will not let me copy it.
I really appreciate that Chris. My truck is burning alot of oil. Im going to try the valve cover n see how that works.
No problem. This is the correct valve cover and the least expensive I could find from a reliable source. Valve cover - amzn.to/2C5MIhd
but what is the difference in the valve cover plz. What exactly please? Also great video!!! I have a 2011 with this exact issue and I was really worried about it. Thanks!!
Do the 6.0 motors from GMC 2009 3500 savanna have the same issues?
KEL Yes and No. lol. I know that doesn’t help much but I will explain. The 6.0 can have a PCV stick and cause this problem. I have seen it. But you don’t see it as much because it’s not an AFM engine. Other than that, the newly listed part (linked below) is made to prevent it on both the 5.3 and the 6.0. Hope this helps.
Chris Arnau AFM?
KEL active fuel management. Where it goes from V8 to V4.
Disculpa no se si eres mecanico pero creo jamás llevaria mi vehículo eres demasiado atravancado en estirar los cables y conectores y ni si quiera limpiaste la perte donde colocaste la nueva tapa
did they fix the issues on 2014 and up trucks?
Jimmy Kimber yes. Different valve cover on it.
Thx! cause mine burns about 1qt every 3k miles. Was looking at the disable devices to turn off v4
I have a 2009 silverado with spark plug #6 fouling by oil. any thoughts?
Elliot Mondragon check the coil pack
Will this fix a cylinder 3 misfire as well?
The answer is 'no' if you haven't already discovered it.
what are your thoughts on catch cans
Currently have this problem on my 06 5.3 vortex. Added a catch can to see how much oil was pulling thru the pcv hose. Drove 200 miles and have 12 oz of oil. That explains the smoke. Will replace valve cover or perhaps weld shields over the holes in the baffles that are lined up with the lifter oil stream.
I wonder if that is a good idea.
I heard Mighty Mouse company makes a good catch can.
The valve cover has no effect on oil consumption at all. The problem is that oil is ingested into the engine somehow and is associated with AFM system on those vehicles - the pcv was a good candidate as the culprit, but from my experience with the 5.3 L engine exhibiting this problem, the issue of oil consumption is directly connected to the AFM lifter failure. This engine did not have the new cover, but ingested oil at a terrific rate for a short time intermittently while the failure was occurring. Personally, I think that the oil consumption would have occurred even with a new cover installed, but I don't know for certain.
If the oil is ingested just before the intake stroke on #7, then the black stuff on the plug will be only on #7 and to a lesser extent on the next plug in the firing order.
The oil consumption issue occurs until the AFM is removed. Somehow the lifters are introducing the oil into the intake as they fail. The AFM lifters have a number of failure modes - all having to do with oil injection on the lifter because that is how the mechanism alters the operation of those four AFM cylinders. So why did they look to the pcv?
The only way that the pcv could be involved would be if the oil was somehow introduced into the area around #7 cylinder in large enough quantities just before intake into #7 occurred. And it would have to be gone before it affected other cylinders. Give me a break. That cover change is a waste of time and money.
If all of the spark plugs look like #7 to some extent, I would say that it is possible that the pcv is picking up oil and pulling it out of the area where it connects to the crankcase (above #7 cylinder). However, it is nearly impossible to suggest a method by which the amount of oil burned can be ascribed to #7 being fouled (BTW the spark plug that you are showing might be burning some oil, but it should not have fouled the plug - indeed the plug shows that it has been operating properly lately, note the tan-colored tip.
Whatever the case, I have serious doubts that this will relieve the consumption issue on most AFM engines. In the meantime, replacing a $70 part will gain the company a steady new stream of income hmmm?
Ok, So I actually thought about just deleting your message. I have not done that in the past on any of my videos, I normally just try to explain why the people are wrong but from your long explanation covering the same point multiple times I am pretty sure it won't help. So I will do this to your long explanation.
First. I would like start off by saying. In my experience (20 years of working at the same GM dealership and 5 years of teaching auto mechanics in college) I have seen this valve cover fix 90% of the oil consumption problems including the skip caused by a fouled out plug (which was not working when the vehicle was being repaired, hence the reason it was at my shop). I was going to explain why, But I will just direct you to the video which I am pretty sure I did a paint by numbers explanation in.
Second. I would like to direct you to GM Service bulletin #10-06-01-008M . I have actually looked it up and you can follow this link which will explain it further. So you have my explanation in the video and GM's engineering team who has way more experience than I have. static.nhtsa.gov/odi/tsbs/2012/SB-10062524-7690.pdf
Third. You have some valid points other than the fact you really don't understand how this system works. The thing I would like to point out that you are correct on, is that you possibly could have an AFM failure causing an oil consumption or because anything is possible. On the other hand, the rest of your post is incorrect and inaccurate. But I do appreciate you watching the video and replying. I am not here to try to sell someone parts for there vehicle that I have not PERSONALLY seen fix vehicles. My current vehicle had this problem, the cover was replaced and I have not had any other issues with it.
Lastly. I pulled this from the bulletin itself. This condition may be caused by two conditions. Oil
pulled through the PCV system or oil spray that is discharged from the AFM pressure relief valve within the crankcase. Under most driving conditions and drive cycles, the discharged oil does not cause a problem. Under certain drive cycles (extended high engine speed operation), in combination with parts at the high end of their tolerance specification, the oil spray quantity may be more than usual, resulting in excessive deposit formation in the piston ring grooves, causing increased oil consumption and cracked or fouled spark plugs (#1 and/or #7).
@@cdarnau I agree with both of you . its a band aid to the AFM System. when it works...it works great but when it dosent it sucks!!!
Chris Arnau my truck has that problem with spark plug number one not the number seven u think still same problem??
@@eduardosuarez5617 ever fix your issue with plug 1. having the same problem after new valve cover was replaced.
@@sethashby6848 no the valve cover was not the problem. I bought a chip to disable the active fuel management and it’s doing fine now.
Bad piston rings. Oil consumption problem.
Id take a shop rag and wipe off the dirt and crud on the head ..it was stuck on the head .
Gilbert Bentley you can on your video.
Burned the original motor. We put the new crate in, turned off the AFM, updated the valve cover and she still burns nearly two Quarts between changes. Just don’t buy one of these trucks. It’s safer
What year?
My 2007 silverado 5.3 is losing 2qts of oil every 500 on freeway miles
yep only on freeway does it smoke, start it up in the morning real bad!
My 2008 Silverado has these same issues. I have to add 2 quarts every week about every 500 miles, smokes at start up. Valve cover change did nothing. If you find the solution let me know please.
Sometimes in mornings it would smoke or on freeway iam installing felpro head gasket kit cuz mine is leaking motor oil from timing chian cover and head gasket cover, and the smoking is cuz i my valve stem gasket were no good
Yes sir ill let you know 👍
