Randy,
You have a collapsed variable hydraulic lifter. The intake and or head will need to be removed to access and replace the lifter.
Yup, it sounds exactly like that. DoD is a bitch. But seeing how great the rest of it is, it could be worth it to both fix the lifter and do the DoD delete.
I believe the lifter is very long and will not clear the head for removal. Also use an OEM lifter not an after market replacement that is made in China. The Chinese metallurgy is too soft and will wearout premature. TRW - Seal Power has had many failures.
I believe you are 100% correct sir!
Is that the first year of the afm
Yup common problem well worth the fix though
The ticking and the misfire are the lifters inside the motor I had a few of those gm 5.3s
Fun fact: look closely at 21:14 this partcular Envoy was assembled in Oklahoma City, Oklahoma.
Its junk then
Snoopy no need for that.
Good catch!
@@snoopy5736 Ya I agree its junk. 75% of okies are always on drugs
Someone said it before, but im commenting it too so it doesnt get lost, you got a collapsed lifter, probably caused by AFM/DOD. Its causing both the tapping you are hearing and the misfire. It shouldnt be too hard to fix, with plenty of resources online telling you how to do so. Seeing how great it looks otherwise, i would even consider doing the AFM/DOD delete.
Santiago Rocha 100% had to do the DOD delete on tons of these and some of the trucks over the past few years
That's what I was going to say. AFM has been an issue with those vintage 5.3 and I believe the 4.8 too. But, I still think he scored on this one. That's a nice Envoy for $1,212. Definitely worth fixing.
My 08 Chevrolet Silverado 5.3 does the same thing I agree it's the AFM collapsed lifter
I 100% agree an if you dont do the delete put a new vlom on when you go with new lifters.
randy! hope you’re staying safe & healthy out there brother. love that truck
Thank you :)
I’m jealous, I just flipped a 2002 GMC envoy sle that was $500. Sold it for $2500 but it was the base model
Did you save the chain link fence?
You can roll it out over your swap to keep from sinking.
do a test put the Envoy XL Denali 4x4 in 4wd where your truck was and see if it gets out
Those 5.3Ls have the active fuel management (AFM). The lifters failing on a cylinder are common. It requires removing the intake manifold and the heads. Might have to replace the camshaft too. You could remove the valve cover on the driver's side, and watch the rocker arms to verify. If the aren't rockin' the lifters have failed.
Wrong era. Afm didn’t come in until 2007.
@@4literfandaniel373 you are misinformed. DOD first appeared in the Envoy and Trailblazer with the 2003 model year.
Freddy Wells I’ll be damned you’re right. My bad. I had no idea😳
Your correct the 5.3 and 4.7 are notorious for that issue however they will run for a long time if you don't mind the tap!
@@jmccord0716 Did the 4.8 get afm? I thought it only went to the 5.3, 6.0, and 6.2
Great video Randy. That GMC looks great. Seeing the Ram, the trailer, and the GMC, all together looked awesome! Hopefully the repair won't be much on the Denali. Waiting on the next upload.
Anyone remember the old red Chevy 2500?
yep
Blinking engine light could mean a coil pack or plug is unattached or can't connect a spark... A lot folks or dealers would loosen plugs and connectors to discourage others from bidding on it.
Noisy lifter won't hurt anything. Had a Buick Regal back in the 80's, bought with the same lifter tapping. Drove it for several years, no problems. Never got better, never got worse. Good car, lasted until our salt laden winter roads finally took their toll. Rear axle stablalizer let go, causing the rear end to lock up and damned near tore the axle right off the car. You guys are extremely fortunate you don't have to put up with rust on cars down there.
Nice! 💪I won mine for $525.00 last year, and gave it to my mother for valentine's day!😌
I have a trailblazer just like that. Except it's 2wd has the 4.2 and is blue. Great buy these are good cars. And mine also had a misfire a while ago lol. New coil packs and spark plugs solved the issue.
Bryson Kuhn the coil packs are a common problem along with the cam solenoid cvvt sensor p0014 code
@@micahhill4786 lol. Had to replace that about a half year ago also
Bryson Kuhn have you replace the thermostat yet on it now that right there is a pain in the ass
Bryson Kuhn that isn’t going to fix a collapsed lifter making all that noise.
my Trailblazer has 266k on her still looks and drives brand new
Everyone of your videos is an adventure. So glad I subscribed! The big Dodge is such a classy truck and I’d proudly roll that big gal around town!
Dang man, I love that trailer!
I picked up a 2005 Grand Cherokee with the HEMI for $600 from Copart and when I got the title if was from Peddle. But the only thing it needed was a starter relay that car runs like a dream no HEMI tick.
The GVW is the total weight of trailer and cargo max. There should be a decal that says max. cargo weight capacity and/or weight of trailer. My guess is you're probably close to maxed out with that Denali on board.
"It helps to see when you're driving"
No truer words were ever spoken
That is a very well maintained Envoy. Looking forward to the video on it. Thanks for the awesome Content Randy 👍
Randy, I've had three GM 5.3's with a collapsed lifter. The absolute cheapest way out and feel confident in your repair is to try to "unstick" that collapsed lifter first. Remove the intake, take an old pushrod you have laying around out of a core motor, file it down a little bit so you can seat it over the collapsed lifter and hit that pushrod with a hammer. If it unsticks (two out of the three I tried this on did unstick for me) it will pop up and you wont have a loose rocker arm anymore. Now to keep it fixed, send your ECM off to have the DOD software deleted where it runs on all eight cylinders all the time because if you put it back together without the reprogram, the first time it goes into AFM mode, that same lifter will collapse again. I use a company in Louisiana for my ECM DOD delete work. Very fast and never had an issue. If it doesn't unstick, well its gonna need a DOD delete kit with new non DOD lifters, a non DOD camshaft and a replacement of that funky intake valley or VLOM I think is what they call it that controls the DOD along with a DOD delete reprogram on the ECM. The one I had to do was on an '07 Suburban with 75K and when I was done it cost me around $1,800 (parts and labor) to fix so you can see where it would be very important to try and unstick that lifter before going any further with the repair. I really hope you can unstick that lifter because that DOD delete kit is no fun. Good luck.
Hi Freddy. I've unstuck lifters the same way, using penetrating oil at the same time. Worked great. I didn't remove the intake.
Randy you have no need to explain to people why you didn't buy a 4WD version, it's your money, your choice.
Keep the quality content coming mate.
Wow! Haven’t seen an Envoy that nice in a while. Nice find 👍
5:00 As long as any of the idiot lights are on, there is something that needs to be addressed and repaired. If the idiot light is flashing, it is something serious. 7:25 That is so you can keep items out of sight, or direct sunlight. 10:45 That might be a simple misfire, or at the worst, a lifter tapping, stuck valve, bent push rod.. If that were a rod knock it would be A LOT louder, and you'd have blue smoke coming out the exhaust. 11:10 The idiot light is flashing.......don't drive the car until you figure out what the problem is. 16:15 While exhaust breaking is very good for the engine, brakes, and a few other components, several municipalities actually prohibit it in residential areas because of the noise level, especially at night. You will also see the occasional sign on the expressway prohibiting exhaust breaking, and that's because that particular stretch of expressway runs close to or even through a residential area. 17:10 Stop at Home Depot and pick up a cheap 6 inch level with a magnet on it, and use it to see if the tongue on your trailer is sitting level, or if it needs adjusting. 17:30 Does part of your "break in period" include an oil change?? Some engines run "break in" oil that needs to be changed out before normal use can begin. 29:50 No need for anyone to cringe.....that's one of the oldest tricks in the book to see if a cylinder is getting spark, although it is usually done with the spark plug in the wire, not just grounding the wire to an exhaust manifold. The wire could be good, but if the spark plug is damaged or just fouled out, it won't spark.
Needs lifters, common in the 5.3L's. inexpensive project.
He probably now needs new cats as well. A flashing check engine requires immediate shutdown.
What an amazing score Randy! I’m uber jealous!
GM has very common issues with their V8 engines. Mainly the 5.3L engines with AFM (active fuel management). The AFM lifters tend to fail, and stick or collapse. Keeping good oil, and plenty of it in the engine, is KEY. These engines also have a bad oil consumption issue, which GM say is "in their specs". ALL YOU NEED TO DO IS REMOVE A VALVE COVER ON SUSPECT MISFIRE CYLINDER, AND WATCH FOR NO MOVEMENT ON THOSE ROCKER ARMS. There is a TSB leading to the passenger side valve cover clogging up in the breather area, as well as piston rings on either cyl#7 or cyl#8 sticking. Make sure you check your oil and change it frequently.
Awesome work and thanks for the content
Edited that ticking sound sounds like a hydraulic lifter
That tick is probably from a DOD (cylinder deactivation) lifter. They make DOD delete kits
One year too early for afm. Afm showed up in 2007.
@@4literfandaniel373 Wrong. The GMT360 chassis got afm in 2005 when they went to Gen IV LH6 5.3's
@@4literfandaniel373 DoD 2003.. Afm, 2005. Stay safe & be well.
Good feeling about this one, nice win Randy! Truck looks great too 😀
Hi Randy!! I’m glad you are happy with your new Truck. 😀
You need to do search for curb weight of vehicle. That’ll give you typical unladen weight. Gross weight is vehicle with max passengers and pay load. GMC envoy curb weight comes in at 4400 to 4800, depending on specs. With v8 and AWD you’re probably at the 4800 mark.
Like your attitude. It is a crap shoot. I am impressed to learn how you solve the mechanical issues. Lots of cars have a lot more life in them'
I bought my GMC Yukon XL denali for 1,425. the only issue was wouldn't start. it had an aftermarket remote start after I removed it and bought a new battery. I daily drive it everyday. I love it.
I enjoy the content! Keep up the great work!!
Ticking noise is most likely the engine tappets
you can buy liquid to quieten the tappets from autozone
Marvel mystery oil does a good job in reducing the noise
Ya probably lack of oil changes and eventually oil pressure or heavy towing
@@neilmurphy845 ..No heavy towing,just normal driving makes a Chevy LS use a lot of oil ,tick due to failing lifters that eat camshafts..they have class action lawsuit for multiple years of GM LS V8's...bad piston rings that the engine eats oil etc..they also have head gasket problems! This is all with light driving and babied,even low miles 55,000 miles they do it!! No not all but more than the other big 3's problems!
These bellow are even problems all models of 5.3 and other ls engines have...just these years/models might stick in court as court is rigged to stick with big companies..

Don't put snake oils in it! That's how people that DON'T KNOW HOW TO FIX CARS OR ARE TOO CHEAP TO FIX CARS "fix" cars. The parts stores make massive amounts of money of you people along with people that replace unneeded parts. This thing has a collapsed lifter. Has to be repaired with real parts and real money.
@@corymagnus7452 ow ya I'm a Toyota or Nissan fan so I know little about gm stuff we don't get them hear in Europe
Smell is a mouse cooking in the engine🤪
Uses way too much gas to be an UberXL. You know that Randy 🤣
Too old too
Nice find. One note, GVWR is the maximum a vehicle CAN weigh loaded to the max with people and cargo. Empty weight probably 5,000 or less.
Stay safe Randy! Great work!
I live in a snowy area never needed 4 wheel drive if you know how to drive you dont need it
About to pick up a 2005 Envoy XL Denali for $300! No engine or transmission! Body & interior is in great great shape,no major body damage or rust no major scratches or cracks! Interior is black with the Navi system/CD player & absolutely pristine! It had the 5.3ltr V8 with AWD but engine was sold! I actually own a 2003 Envoy XLT with the 4.3ltr inline 6 with over 276,000 miles and love it! It's not in the best of shape compared to the Denali I'm purchasing is the reason I'm buying the Denali. Plus the Denali is something I've always wanted! My (?) for the wrench heads is are the 5.3's as reliable & maintenance friendly as the 4.3ltr and is this deal worth it! Still keeping my 2003 Envoy XLT for a daily.
Nice buy man keep up the good work.
Randy you need some concrete my friend. I really like the Envoy, can't lose at that price
Same thing happened to a TrailBlazer I looked at recently, darn lifters! These also like to blow head gaskets around this mileage
Is it a 'must fix'? .... Considering price, age, mileage etc.. would it be an O.K. & reliable A to B without repair.. (Dod/afm too involved + pricey?)? Clean & really nice imho, otherwise! Really like it. Stay safe & be well.
This my 3rd time watching this video luv ur channel 🤘🏾
Looks like a great deal and the car fax was awesome!!
Love the videos Randy!
I appreciate that!
Great truck. Info you need: GMC Envoy: Flashing Check Engine Light Diagnosis. ... When your engine is misfiring, it is dumping raw fuel into the exhaust. This raw fuel can detonate, which causes damage to the catalytic converter and the exhaust system itself. There can be other situations that can cause the check engine light to blink as well but I’ll bet it’s a spark plug/coil pack situation.
Sweet deal . I love that charger gonna miss it maybe 1 more video blowing the cobwebs out ! 🚨🚨
Man that truck is nice I love those denalis I sure do hope it can be salvaged good luck Randy great video
Another great purchase, well done Randy
Thanks 👍
You work so hard man!
Hey, Great to see the old brown leather jacket back in action. Keep up the good work, Try and put out a video every other day. Thumbs Up!!!
Hey Randy, to see if it's the coil wire is the issue, try switching the wire to another cylinder, then clear the code and if it comes back misfire at the other cylinder, then most likely it's the wire. Good luck!
Great video randy
Displacement on demand or "DOD" started in Envoys and Impala SS 5.3 engines for this model. Probably a collapsed AFM lifter on cylinder # 1, 4, 6 or 7. Very common. I have a 2007 that sounds identical to it with a collapsed AFM lifter on number 7.
Trailer weight is 7000 pounds and you have to include in that the weight of the trailer so if trailer weighs 2000 then you can put additional 5000 on the deck. Keep doing what your doing man love the content- Brandon K
Keep up the good work randy, im about to start my youtube channel. Im a dealer and do copart, Manheim and a couple more auctions. I usually fix my own vehicles as well. So hopefully once i start my channel i can get a good following like you ive been watchin since almost urber man. Lol
I wish you all the best!! You'll do great!
Randy only use ac delco platinum plugs this comes from an auto mechanic that way you know it will be really great running car and they will not burn up the. The plug love that car and your truck. Is great and you brought the best you could afford. I know. Diesel motors are very economical great video loved it
That’s the typical gm lifter tap. The afm on the motor causes the lifters to go bad
You probably have a fuel system Lean code. The intake boot past the mass airflow sensor was all torn up you could see it in the video.
WeirdBeard is a cool guy he has his kids and he helps them on their projects man it must be a blessing you have friends like the ones you do. TK, WEIRD BEARD, CARR, MONKEY WRENCH MIKE. And you all have never brought drama to each other. A++, keep up and great job. Is your family ever going too do more shows with you?
Can’t wait to see you diagnose and repair the GMC Denali.
Have fun with it . I have a 05 envoy Denali and I love it.
I had an 07 F250 long bed crew cab with the 6.0. Drive from Huston to Palm Beach. Ran 70 mph and got 12 miles per gal. Trailer was over 11000 lbs. got dark and didn't know t was on the back.
I LOVE my 2008 Envoy Denali. The nicest vehicle I've ever owned!
Cant wait to see you get your hands into that motor
Am I the only woman who watches these videos?? 😂 I love watching you get these cars fixed up! It’s so interesting!
Most people in general don't watch these videos.
It is Sunday, 10th of May in Australia & Mothers' day so, from me, a Happy Mothers' Day to Jessica & your respective Mums.
At 7.30 pm, you lowered the trailer back down, which is far easier than lowering it up. Lovl.
In Australia, GVM is the total mass of the trailer & load & the GVM of the vehicle is the total weight of the vehicle with all liquids (e.g. fuel, oils & coolant) occupants & luggage, etc. So 2930 is that weight, as opposed to the tare weight, which is the vehicle without fluids, occupants & luggage. CVM is the weight of the tow vehicle, fully loaded & anything the vehicle is towing, in this case, the vehicle plus trailer & it's load.
Hope that helps clear your queries, Randy.
The Cummins will pull whatever you put behind it. A general rule of thumb with the 6.7 is when towing, keep RPM's at or above 2,000rpms. It's the sweet spot for the engine. It gives you enough power left in the RPM range to pull but also gets you high enough in the RPM's to allow the Exhaust Brake to do something when you let off.
It crazy to see how common this is, I just bought a 07 Denali 5.3 envoy with 169 k with the EXACT symptoms. Yours is cylinder 1 mine is 7 the same side bunch back cylinder. It is the collapsed lifter from DOD AfM as others have said for sure. I was able to pull valve cover verify the intake rocker wasn’t moving, then pulled intake and valley cover VLOM and insert a homemade steel rod into the oil passage for that lifter and hit it with a air hammer lightly and quickly which popped the litter right back open. I then used hptuners and 2 credits to unlock ecu and disabled DOD to prevent it from going into 4 cyl mode again… I closed off the oil passage where the oil sensor is in vlom with a metal bushing and loctite, and popped the retaining rings off the solenoids on the vlom and I pulled them off. Put it all back together and have been running 1000 miles plus so far runs like new smooth as silk. I did a couple vids on it.
i'm so jealous Randy! what a beautiful steal you got!
Randy, great to see that finally you bought a good car for profit.
Thanks Randy stay safe 👍😷
You have an army of loyal trusted friends for help Randy.
Possible exhaust leak or lifter problem
I love all the awesome videos
Thank you.
Randy the RAMs exhaust brake COULD use engine oil and burn more fuel. I cant speak toward the Cummins they put in regular trucks but the tractor trailer versions due burn oil and fuel with it on. Just a friendly FYI. Just something to keep in mind. Basically how a Jacobs Brake works is it holds the exhaust valve open which essentially turns the engine into a air compressor. Good purchase on the envoy though! That looks like a real money maker.
We have a 2003 envoy xl. Has everything but v8. Randy, that envoy has bags in the back that airs up the back to ride level.
Two things I noticed: It seems like the fan clutch is seized so the fan is running wide open, you can hear the fan rev with the engine, and unless it's really hot it shouldn't do that. Also pause it at 13:11 and you'll see there is a massive hole in the air intake after the MAF which will cause issues, and is probably contributing to the misfire. The tapping sounds like top end, maybe a lifter. The good thing is, the 5.3 is in pretty much any GM truck, so even if you had a worst case scenario which isn't likely, you could get an engine relatively easily and cheap.
Is there a drain that us blocked or do you just need to install ones
That some great history!! I almost bought a Silverado recently i went to car fax it and zero records were found, 2 owner but nothing for history just seemed weird
Swap out the lifters, great find Randy👍
I just realized you're wearing the nike air max 95.
The dealership it was originally purchased and maintained at is less than an hour away from where I live. What a small world we live in.
Hey,
Cool SUV you got there dude!
Good luck👍
Hey, thanks!
@@AutoAuctionRebuilds 👍
Although the dealership would never tell you this, but personally, i would do an oil change at 500 miles on a brand new engines. You will find allot of metal in the oil, which is normal. I wouldn't want metal suspended in my oil any longer then you needed. Something an old mechanic once told me so I did it and under bright light you could see the metal in the oil.
Love the long videos randy!! 🤘👍
Glad you like them!
Bro what you have heard is absolutely correct once it gets more miles your mileage will go up ! My 99 turbo diesel when it was new i was getting 16, 17 miles to the gallon my truck was also a 4x4 after about a year my mileage was around 21.
Aye happy to see a new video today! Can't wait to see the new car!
Hope you enjoyed it!
I see you randy with the air max 95’s
Just to fix a thic lifter just add lucas oil on your next oil changed it will help out alot.
Do you think the engine brake being on makes any difference in the fuel mileage?
I heard that noise on a friend trailblazer ss it was a broken valve spring...i change that spring and runs like new my friend was very happy it was just a spring...
on the RAM, use the REAR tire pressure for LIGHT LOADS,
it will smooth the ride out, and you can haul a reasonable amount of weight even with the lower pressures
Randy that trailer was the best investment you have made.That is max. capacity that you can tow.
Randy, I’m a mechanic and I cringe every time you drive a vehicle with the check engine light flashing. That flashing means that a SEVERE MISSFIRE is detected. If you continue to do so you run the risk of DAMAGING THE CATS. unburned fuel is going through the exhaust and cooking the cats. SHUT THE ENGINE OFF IMMEDIATELY
It looks great. I think it's a win! Wipe your brow on that one. Love that Ram by the way.
