Hey Anthony, I really like your videos and am a fan, just FYI I like subscribe have the bell notification and I'm not receiving any and I checked the setting's on my phone. I was shocked to see how many episodes I have missed like months worth, because I'm in Australia I just assumed you either went on near summer holidays and only till finally going down my inbox on this site a comment was liked from ages ago was aware you were still making content!!! Anyways I have much to catch up on I some binge watching to do
Hey Andrew, sorry about the late reply. That sucks you haven't been receiving any of the notifications. Maybe try hitting the bell notification again? Hope you're liking the most recent content!
My 11 5.3 started running rough and intake sounded wierd, so I pulled the intake and found a quart of oil expecially going into cylinder 6 where I have a misfire code, so I pulled the valve cover and found that I have the upgraded cover so I will now be installing an oil catch can!
You'll also want to look into this for the other side th-cam.com/video/q6G5ZiBpmUE/w-d-xo.htmlsi=Z8NFxLHaV7quP1C8
Even the new design will fail just take it off and drill little holes in it, how is it now though did the catch can even do anything?
I got a 6.2 L92 and my passenger valve cover vent leaks oil to my intake. Not suite if I should hook up a catch can on the passenger side of valve cover? Or change valve covers or plug ports.
Look into these catch cans for your vehicle rxcatchcans.com/
So I'm assuming the outlet port on the catch can connects to the top of the manifold. I have a 2014 escalade with a 6.2 and I found the pcv in the back of the drivers side valve cover, but when I traced the line it hits some type of junction with a plug in then comes out the other side and connects to a port on top of the manifold not the throttle body . Is this where I connect mine to the output side of my catch can. And what is that relay between the lines off the pcv system?
You need this brand of oil catch can www.tracylewisperformance.com/
Have a 2000 LS1. You have a video over the change of the entire pcv system?
Not for the LS1 specifically, you might find this video interesting. This is how I keep my intake clean th-cam.com/video/q6G5ZiBpmUE/w-d-xo.html
I have an 06 yukon..same problem oi in the throtlebody..i order a new valve cover to install it..hope that oil & smoke problem goes away..
I would still install an oil catch can on that side and an oil seperator in the other side th-cam.com/video/q6G5ZiBpmUE/w-d-xo.html
Catch cans are necessary indeed 👍 more preventative maintenance on top of updated parts. I wouldn't trust a system like that on the cover. Vapors at temp can still travel without baffling.
I the updated cover and existing catch can will work really well. The catch can already does a really good job.
@@AnthonyJ350 yes the updated cover is better than factory. The effort is to be noted on that.
@@AnthonyJ350 where did you purchased the catch can kit?
@@tellitallnow3914 I’m guess he didn’t get back to you?
Hey not sure if you still reply but I’m planning to do this and replace the drivers side valve cover, I was wondering if I should also replace the passenger side? I just got my truck for less than a year now and just want to do some preventive maintenance and what not
I would leave the passenger side alone if it's not leaking. I'd only redo both if you were having them powder coated.
Appreciate the video brother. Ordered the l/h valve cover you recommended. Got a healthy engine that likes to suck a little bit of oil into the intake manifold from the left hand valve cover. Problem solved. Thanks again.
So glad the updated part helped!
Anthony, I have watched many of you videos and do enjoy learning as my job did not take me into the “LS” word. Is the fitting a true fixed oriface now or does it still have a spring-loaded valve inside? Many imports with much smaller displacement have been running a fixed oriface for years with no issue. After all, it is a calculated vacuum leak! Just small.
Thanks for all of the videos!
Thanks for watching! I didn't really inspect it but I'm pretty sure it's just a fixed orifice. Hope that clarifies.
Most of these problems are from the high volume oil pumps necessary on the AFM/ DOD engines. They just flood the tops of the engines through the lifter/ pushrods. Poor design just trying to please the govt with fuel economy and supposedly emissions.
@@user-ev4pb9xj7e Government wants higher MPG in the truck category, engineering has to find a way to squeeze more MPG's somewhere. I don't think anyone is pulling a backhoe to the job site with a tricycle. Poor design or not, variable valve timing, late intake valve opening, or lifter failure due to lack of oil changes. Everyone who builds a truck have to figure it out. As for poor design, it is funny how everything is perfect until it ain't! Suggestions?
Do you know if the gen4 Ls engines already have something like this? Other half has a 07 envoy with the 5.3, it blows a cloud of smoke for 10 seconds on cold starts. Trying to narrow down what's going on here before I go yanking the heads off and replacing valve seals and things. Replaced a cracked vacuum hose for the pcv and it looked wet inside. I'm used to adding a quart between oil changes on my gm trucks but dang. Guess if it's rings i'm gonna keep adding oil, that oil pan looks like a pain in the ass to get off with the axle going through it. Definitely not coolant either.
I believe you would already have the updated valve cover. What oil are you using? I'm using Castrol 5W40 to quiet my engine down after I had a cam put in it th-cam.com/video/zVjVAAikdYc/w-d-xo.html
Have you figured it out yet running into the same problem had a head gasket problem not to long ago so I’ve already did head gasket valve seals an what not but when I pulled the intake of it had a lot of oil in her
@@doyleboggess3791 it seemed to have slowed it a lot though i will say i have a minor oil leak somewhere down below. did an oil change about 2 months ago and havent had low oil level or any smokey startups since.
The baffling in the valve cover was much bigger in the newer cover.
I have a 2014 Yukon XL 5.3L V8 that has a misfire on the 7th cylinder. This vehicle has the active fuel management. I pulled the spark plug and there was oil on the spark plug. Tell me where you think the oil is coming from to be getting on the spark plug that is making it misfire? Could it be rings are bad, lifters might be bad? I have not done a compression test on the 7th cylinder yet or a leak down test. Please give me what you think might be where the oil is coming from.
Look into an oil catch can like this rxcatchcans.com/
sounds like stuck lifter. wet with fuel not oil check for spark then do comp. test if good spark
Hole in the piston
That “updated” cover you bought will still have issues. Drill a few relief holes along the bottom of the baffle to help drain the oil back out
Thanks for the tip!
I have the valve cover and it still lets lots of oil get in the intake i just did the intake gasket on my 04 5.3 and when i turned it upside down twice i had oil puddles
Put a catch can on the driver's side with the updated valve cover and put this oil separator on the passenger side th-cam.com/video/q6G5ZiBpmUE/w-d-xo.htmlsi=kT30hoYytx0NOUDl
I am having the issue where my truck has started smoking at first start in the morning and now some throughout the day at random times but not always but only for a few sec blue cloud of smoke, could this help my issue? It’s a 2011 chevy Silverado
It might if yours isn't the updated design already. I would take off the throttle body off and inspect the intake manifold if there's a bunch of oil in there. I would also look into a catch can th-cam.com/video/DJ7Z2F51fzs/w-d-xo.html
I have the same issue with my 04 yukon denali. Its pushed oil into the throttle body and smoje at start up and oil consumption. Im about 99% positive its the pcv in the valave cover.
@@knobstonestickbows4962 This with a baffled oil catch can will help a lot.

Hello guys,
This past weekend replaced the cover on my 2012 tahoe ppv 5.3, but I noticed that I had already the updated cover, my problem is little weird, no cold start smoke, no hight rpm's smoke, but when Im going down a hill just iddling when acelerate back trow bunch of smoke (blue), but after that no smoke. Untill iddle againg for like 10 seconds
I'd clean the intake manifold and look into running an oil catch can th-cam.com/video/DJ7Z2F51fzs/w-d-xo.htmlsi=qaDSj4dPZryof-5a
Wat u do on hot wires on bac of alternator
Oh they're all upgraded, th-cam.com/video/uzcVPcldvBU/w-d-xo.html
How much would it cost me to upgrade my 2010 5.3 top end like you did? What parts did you use and how much did it improve performance? Thanks
Few grand when you have a professional perform the work. We focused on top end durability (Melling oil pump, hardened push rods and caged trunion upgrade for the rockers). The TBSS intake manifold and Comp Cams cam gave much better performance in the mid-range of the power band.
Will oil in the intake cause excessive white smoke? I think I know the answer to this, but not so sure. Here’s why. An 01 GMC 4.8 is smoking, and I mean a lot! I’ve reworked the heads, so hopefully I can rule out head or gasket problems. If I drive it, it runs very smooth and no smoke. But about 5 minutes later, it looks like I’m spraying for mosquito’s. Still running fine, oil and temp normal. I’m completely at wits end, can anyone help?
Are you losing coolant? Found this site procarmechanics.com/types-of-smoke-from-your-car-tailpipe-what-it-indicates/
Anthony J350. Thanks for the link! I guess I know what I gotta do, but at 70 yrs old things seem to be a little tougher. I guess I’ll read the plugs, try and nail it down to a cylinder. Then pull the heads and get the shop to pressure test them again. Check my gasket and see what’s happening there. I was hopeful that oil in the intake may be my answer. I haven’t tried to measure missing coolant. My smoke doesn’t seem to be steam though. I’m beginning to dislike LS engines, Lol
Should go with an LS6 valley cover with a built in valve cover....works WAY better than that valve cover you got.
I was looking into that, but decided to go with the updated valve cover for simplicity of install and don't have to modify the block to make it fit. Correct me if I'm wrong, but I believe you have to make a small modification to make that valley cover fit unless you have an LS6 block.
@@AnthonyJ350 no mods needed for a gen3 block. I've had one in my 05 5.3 for years along with a catchcans.com can. Intake is dry as a bone at 215k miles.
@@eddiefromcali Good to know, I'm going to run this one for our video purposes but I'll make sure to mention the LS6 valley cover in follow up videos to give people more choices. Thank you!
Yup, LS6 Valley cover does work way better
LS6 valley cover and replace valve cover with old style removable PCV?
Why is there a pcv valve on back of drivers side valve cover with hose going to intake plenum and then the hose off p/s valve cover to t/b
One aide is normal driving the other is wide open throttle conditions
@@AnthonyJ350 the passenger side hose is to allow fresh filtered air to enter the engine so it can be sucked out by the driver side hose. If you don’t have a way for air to enter the engine the pcv system will pull a vacuum on the crankcase. The passenger side hose must be connected downstream of the MAF sensor so you don’t have false air (MAF bypass). And yes under WOT conditions there is enough blow by that the passenger side hose reverses direction and allows pressure in the crankcase to vent to the intake to be burned.
Can you tell the valve covers apart without taking them off? Have a GTO that is losing oil. No leaks. No exhaust smoke either
I don't think you can.
If it's not leaking and not burning oil, then where is it magically disappearing too? It's burning it, you're just not seeing it. Remove the intake tube and flip open the throttle body butterfly and look at the valley floor of your intake with a flashlight. Probably coated in oil. Punch it on the highway from like 20 mph to 100 mph. Mash it up the floor and don't let up. Look out the back window as you do so and after you let off the throttle.
@@tirefrier8253 ok. I have a catch can on it. Ill have to look into it. I heard the LS2’s just use oil when you cam them. No real way to fix it besides tearing it down and doing a bore and new rings and doing an updated PCV system. It only burns a quart between oil changes
Is it integrated into the valve cover?
Yes it is
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.
You can't replace them, it's just a baffled orifice. Run an oil catch can and you're good.
@@AnthonyJ350 Ah okay cool! Thanks for quick reply! I sprayed some carb cleaner in it and up the hose.
don't need so called updated valve cover or catch can clean the valve cover and drill a few extra holes in the baffle
@@shaunnesbit1734 If that's what you want to do. Give an update of the intake after 100,000 KM
Actually a bolt extractor gets it out. Then lightly hammer in new one
Can i use 1 can for both sides?
I don't think so. The system feeds different on the other side.
So only the passenger side is updated ?
Driver's side because that's where the orifice is for the PCV system is. The passenger side is sealed.
Will this work on a pontiac GXP
You would think so. I would just verify the mounts for the coil packs are the same.
My 2000 Silverado 5.3l has a PCV in the back side of the driver's side valve cover. Same location as the "orifice" in the one you've shown. The oil doesn't come from there on the older motors. The older style had a VERY SIMILAR valve cover on the pass side, to what the newer ones like yours have. It's literally just moved back a hair. Why people see "so much oil" in the throttle body of the old ones compared to new ones, is because the pass side vacuum line pulls from the throttle body itself. In like 03/04 and newer, like yours, it moves the vacuum back to the plastic part of the intake. So it still sucks the oil in, but puts it behind the TB so you don't see it as much.
Also, something you can do to cut down on some of this oil, is to 1) Install catch cans. (I know. That's a pain). And 2) The "CHEAP" solution, is to pull the valve covers, remove the baffle plates and drill some drain holes in them. Then tap 4mm holes where the rivets were and reinstall the baffles. If you own a TIG, you can tack them back in place, but if you don't know how to weld alum, don't try this. Also, be sure to loc-tite the screws you tapped holes for so they don't come out. Finally, you can re-rivet them if you are good enough.
I've personally had "Limited" success using a rivnut setup in the drilled holes, but without through hole access, they are tough to get seated right.
Thanks for sharing your experience!
You don't need to remove the baffle. Just drill some holes at the bottom of the baffle and that's all you need to do. No sense in drilling all the rivets out.
I see that mechman elite on there
Yup, it's been pretty good so far.
Is this for escalade ? 07
Any engine where the PCV outlet is on the valve cover. I would pull it off to see if you already have the updated design, or see if you can buy the new one and see if it's refundable.
I was told the baffle was bad and caused higher crank pressure and blow by so it's better delete the baffle and only use a catch can
I been using this just fine. Is it a daily driver vehicle that tends to stay below 3,000rpm or something on weekends that your whining out the engine?
Same Issue On My 2006 GMC Sierra 1500

@@DeepPoeticSociety They're not bad to do. Really depends how much space and whether you buy universal or vehicle specific.
don't need new valve cover just clean it and drill extra drain holes
Just did that on my 07 yukon a few weeks back, 2500 miles in and most of the oil Consumption has stopped. Saved me $165 bucks for the newest valve cover update.

Yup. Enlarge the holes and replace the pcv with the fixed orifice style.

You figured out how to fast forward! Good job!
Why bother with a catch can if you already have a mid-year 2011 or newer 5.3 with all the proper updates from the factory????
I would rather double it up and help slow it down. That's just a preference because I don't see OCC always as a guarantee.
The newer engines need a catch can even more since they have the displacement on demand crap...they have a tendency to drink up oil quicker than the older gen LS.
@@eddiefromcali I love getting 22mpg highway with the displacement on demand in my eight passenger 6000lbs Suburban. I haven't noticed any oil consumption. It can't hurt it putting a catch can in just see if it works on the updated newer models.
Mines is an 11 and it uses oil like crazy...not impressed.
Too bad GM didn't warranty it though.
2005 truck I wouldn't expect them too. Seen so many of these trucks go over 300,000KM
@@AnthonyJ350 2005, no, but ever since they came out with the AFM oil consumption as been an issue. And that is the 2007.5 model. They always denied it as they said a quart in a thousand miles is normal. When one can't stand behind their product, I won't own another. Now, the AFM/DFM is such a problem on the 5.3 that they are discontinued starting this month. Blaming it one shortage of semiconductors. Another damn live by Government Motors!!!

@@AnthonyJ350 If you do any research on them since 2007.5 it's a major issue. Oil consumption and lifter issues. Many do a DOD and get rid of the problem. Their new style is also causing issues. Could explain why now they're ending the AFM/DFM on the 5.3 and blaming on a shortage of semiconductors. GM just refuses to stand behind the problem.
@@billmonroe8826 I'm sure they have issues. But what's the percentage of affected? I still think GM push rods engines are the best gas V8s you can get. My next truck will be a 6.0L without DOD because I like simplicity and I want the bigger engine in the 2018s.

That large square opening on the left is the problem. You need a shield over it. At least 3/8 inch between the shield and the opening.
