Major Oil Loss!!! The GM Valve Cover Swap That Could Save Your 5.3 LS Engine / Motor How To Tutorial

- My 2006 GMC Envoy Denali was burning through a quart of oil for every tank of gas. Something had to be done, and a quick search landed me at the valve cover. GM designed them wrong, causing oil loss and lifter failures on many of their trucks and SUV's. This swap takes 15-30 minutes, and costs less than the oil you would burn.
This really works!!! I quit burning oil once the swap was completed. Unfortunately, I was sideswiped a couple months later. Follow me to see what I've replaced it with. A jaguar X-Type Sportwagon!!!

You should have added a few holes lined up acrross where that tiny hole is at the end and also drilled out the hole at the end bigger for better oil dispursement that is best fix for the pcv isdues
You mentioned they fixed it after 06. My 07 5.3 NBS Silverado 1500 had the old style valve cover. Just putting it out there so people don't think they're in the clear if their vehicle is 06+! 5:11
It starte with the 07.5. They they never made any attempt to fix the oil consumption problem. GM actually said the oil consumption was normal in order to not warranty anything. The sad part is that GM continued to build their AFM system the same way for years! They must pay their engineers to sit on their ass and not fix their issues!
Very helpful, did it by my own and saved me a couple bucks thanks to you! Lifesaver
2010 Chevy Avalanche 5.3 owner here. My valve covers have never been replaced and apparently are the older ones you have replaced and reported problems with. I have never had any oil consumption until just recently, 153k on the odometer. Saw about a quart missing after 1.5k miles after oil change, i did have to replace the oil pressure sensor and filter so I wonder if that has anything to do with consumption either. Anyways worth mentioning my “newer” GM also came with older VC’s.
Whats the part number or descriptions to assure i find new updated vlave vover.?
I have the 5.3 L but I'm going use the old covers and drill out as suggested by many mechanics and several TH-cam videos. About 13 holes in total on the underside baffle and and driil out the PCV hole larger. About 1/4 hole.
Also one guy is advising a full court of ATF in engine.
My 5.3L suburban started using a lot of oil suddenly when I started driving it more in the winter and idling a lot.
I'm using synthetic oil now the last three changes.
What's the purpose of drilling holes?
@@sean.g4516 so the oil can drain from the secondary cover inside the main cover instead of getting sucked into the pcv
Happy to see new content!
Much more in the works!
7:54 so how much has the oil consumption improved from the 1 quart per each gas fill up? I need to change my pcv since I burn 1 quart every 700 miles.
Did a 280K mi. VC gasket job recently. They were the originals lmao. The engine certainly burns a certain amount of oil due to hi mileage, but the main oil loss issue has always been leakage -- not any more. Oil consumption has been very negligible since forever. My guess is your oil consuption through the pcv system is because there is apparently no valve in the positive crankcase vent. Mine has a valve & no problems.
I’ve done this upgraded valve cover in my 2006 Silverado with the 5.3 vortec years ago and it changed absolutely nothing. The oil consumption was still as before. What the real culprit is, is that there is but one tiny oil drain hole which if I remember correct is after the Pcv valve which makes absolutely no sense as the oil has already been sucked into the intake by then. You need to drill about four extra small holes on the baffle about an inch apart or so. then clean the crap out of it with brake cleaner and an air compressor. I did this on mine and the oil consumption has been next to zero.
Here’s a link to the TH-cam video I followed
m.th-cam.com/video/CePGNsAkcYQ/w-d-xo.html
You modified both valve covers ? or just the driver side ? Also what size drill bit did you use ?
Put a pct. Valve in the line between the valve cover and the intake. That stopped mine from using oil.
where you get that part. sir David
we all miss yuh x come backk
Working on some videos for the coming month!
My 2009 Chevy Silverado 5.3 engine sounds good for 10 minutes after I turn on then I driving down the street then the truck starts smoking from the muffler starts to idle and start to buck when I take off from a complete stop at a stop sign then the traction control light starts with the check engine light to so if I put a new valve cover this will solve my problem.
Hi there , did it solve the oil consp so far. What is your feedback
Now you start to consume oil because it doesn't have the drains that the original factory one has, that was my experience, I opened them myself. greetings
What year did they update the valve cover and did the 6.2 have this issue as well
What if you got 306. Misfire
Hope your okay. Update on the oil consumption? I have a 2001 GMC Sierra 5.3 with over 377,000 mile, has misfires and losses a lot of oil. Any thoughts
Just did one on a 2010 had old valve cover
You could have cleaned the coils and brackets
My 2012 Silverado 5.3 is going through one quart oil every 800 miles. I discovered the oil is going into cylinder #7, spark plug is covered in oil. Will changing the valve cover to the modified one fix this problem?
Most likely valve seals.
@@goch907
I don't recall you stating what the torque on the valve cover bolts were
Yeah that’s very important, could leak through grommets if torque isn’t right
106 inch pounds
I have a 2000 gmc 2500 6.0, #1 what kind of engine do i have ,sl ?, 2 is this an issue as this vid points out for me.
Change only on the driver side or both valve covers?
Did you replace both or just driver side?
@@michaelgarcia4117 driver side
Looks like you already had the updated valve cover? You have the built in PCV...
Where did you purchase the upgraded valve covers for the 5.3. Thanks in Advance
He said Rock Auto at the beginning of the video.
You never showed the last nut on the rigth side which was the hardest to get to! Why No!
do you only have to do 1 side or both? and is it pretty much all 5.3l needs this updated valve cover?
GM fixed the problem a few years later, but it was most LS engines with displacement on demand.
@@dougiesadventuresreviews2167 i dont know if i have that, my truck is an 05 silverado 1500 w/ 5.3l
@@extorter I believe they started DOD in 2007 for the Silverado.
So would a bad pcv valve cause an oil leak?
I would add the PCV “valve” on these is just a tube.
Amazing video! Thanks.
Thank you for the feedback. 🙂
You said you got the part from RockAuto? Do you have a link for it?
im having trouble front seal keeps leaking will this stop it i hear the valve cover can make build up and push out the front seal is it true ?
4:52 why did you say the pcv is just a tube? I have the updated cover but my cover is old again and pcv needs changed. You threw me off and called it pcv later on in the video. Thanks for showing though.
It's really not a pcv. A pcv is like a check valve. On this engine it's clear through both ways. No valve inside. Hope that answers your question
@@sawyerbennett8227 So do these trucks not have a PCV? I've read plenty of reviews that got this cover and fixed their oil consumption issue but not sure if some had to replace updated cover twice.
5.3 is the best engine EVER!!!!!!!😍🥰👏🦾
Only if you remove all that AFM sh*t the government put on them.
6.0
@mypony7310 5.3 is better its proven....
Do tou have e. Part number
@@jonsanders3367that’s good to hear if it’s true
So How Much did oil consumption improve
Did you buy a GM parts or after market valve cover?
Was it the SKP?
where to buy valve cover?
I found mine on Amazon.
@@jamesbarlowjr.3762 Part number?
What’s the torque specs on the valve code and coil pack?
On my 5.3 Silverado it's 106 inch Lbs for cover bolts, and the coill pack bracket just snug them down. I've seen vids where they say 96 in Lbs but my shop book says 106 for a 1999 Z71 5.3 Vortec
Did the valve cover come with the gasket also?
@ 45 seconds he states it comes with a gasket and pcv valve
Yes it did
Is their a part number or anything? What's the magic words to find new updated valve cover? I have 06 tahoe that after sitting awhile it will belch smoke on startup. Any help appreciated.
What type of oil you used to spread on the gasket?
motor oil
That gasket should be clean and dry do not ever put oil on a new gasket like that unless specified in the instructions
Go further and replace with an earlier replacement. My 02 has an old school removeable PCV.
What was the outcome?
Ran great and quit burning oil until someone totaled out the car for me. 😂
Did you only replace the one side ?
The driver’s side is the only one that needs replaced. It had the PCV valve on that side.
@@dougiesadventuresreviews2167 thank you for your timely response 👍
I don't know how long you owned that vehicle but your valve cover shows lack of service! The rest of your engine will look the same way.
Post the link
Link.
You should have added a few holes lined up acrross where that tiny hole is at the end and also drilled out the hole at the end bigger for better oil dispursement that is best fix for the pcv isdues
Do you have a picture or drawing showing this tip? If I gave my email could you give a bit fuller explanation of how to do this? Thank you.
