It turned out the lifter might not have failed after all. Still not sure why the pushrod bent but the engine builder said it looks more like the piston had a hot spot due to running low octane gas. Either way this new long block is DOD bullet proofed, warrantied, and will see premium fuel from here on out.
Congratulations getting it back... No joke though... Got a 2018 International LT, took my boos 4 months to find that stupid plastic reservoir coolant tank. Mines held together with RTV amd hope lol cracked from top to bottom with those little cute 1/4 lateral cracks plastic does all stacked all the way down. Ive been waiting for it to start breaking bolts loose. Found one yesterday finally! I totally understand. Lol
Nick i am in my 80's and i got a big kick out of seeing your amazing beautiful Kids❤...May God Bless them and your family
🙏🙏👀👍
Shoe🇺🇸
Most likely if it had a hot spot, the plug broke first and got between the piston and valve as it was trying to open and bent the pushrod in the process
Just a question Nick. You said you were in the middle of harvest. Did I miss something? I didn't see any planting or spraying lol. Unless I'm stupid or something.
Blew a 6.0L GMC up the same way.
I work for a chevy dealership in the northern twin cities. We had a customers Silverado that needed a new 6.2 for the exact same reason as you. His truck sat on our lot for 14 months before he got it back. We ended up replacing his tires as well, because they developed flat spots from sitting in the exact same spot the entire time. He was patient with us because he knew about the supply shortages, and was surprised when he found out we replaced his tires for free.
That's so sad and very generous of you guys. It isn't the dealers fault, the supply chain has wreaked havoc on parts.
what dealership is that a am in the market for a new truck
Doesn't the camaro have 6.2L just swap a car short block in the truck.
@@shanerussell8894 I work for the mauer auto group. We have a Chevy store in Anoka, MN, as well as a Buick/GMC and Chevy stores in inver grove heights, MN. We’d love to help you.
That my friend, is called customer service. Good job
Cylinder deactivation bs and modern choked up diesels with DEF is exactly what led me to purchase my 2022 Ford F350 with 7.3 gas. Pulls like a diesel for everyting up to about 15,000 pounds. Old school pushrods, larger coolant chambers and 400 pounds of torque at 1500 rpm and max torque of 475 at 4000 rpm. Love it.
You made a good choice, gm 6.0 or 6.6 gas and the Ford 7.3 and now 6.8 gas are the way to go under 20k lbs.
I bought a 2014 F150 with the 5.0 to avoid the fuel saving issue. I just dropped $6K in having my door jams cut off and new ones welded in because Ford has a leaking problem with the third brake light. Water seeps into the cabin going down to the door jams and rust the body from the inside out. Looking at the current cost of replacing the vehicle, this was a smarter investment to have it repaired. Your repairing the engine is a much wiser investment. You have the dirt roads that beat your truck up, we have huge amounts of salt that rots our trucks away....an uphill battle for longevity out of our vehicles. Thank you Ford, GM and DOT.
No afm. That's why I love my 02 Z71 Silverado 4x4. 325,000 miles and never been apart or out of the truck. Runs quiet as a church mouse. Best truck I've ever owned. I don't baby it, I still get on it and she screams. She's well optioned, and everything still works like new. Good maintenance. That's the key, and no active fuel management.
That’s life..Yep. I bought a 2011 Ford Flex brand new. The family LOVED that Flex. The Duratec V6 engine has the water pump inside the engine and run by the timing chain. When the pump seals fail, it dumps antifreeze into the oil pan and destroys the engine. Got 8 years and 80,000 miles before it blew up. The market worth was about $8,000 but it was worth at least double that to me! The car manufacturers don’t give to two turtle doves about quality, just narrowly making the most amount of money possible.
I really realize that my Engine is a Unicorn watching these videos! 333000 miles in a 5.3L with AFM and still going
To be able to work on most of the engine is awesome. I have a older pick up and when it goes down, I have to pay someone to fix it. Labor is more then the parts and etc. You are so bless to be able to do this. God Bless you all.
When pulling the 5.3L we took the motor mounts off and twisted the motor around inside the frame so the fly wheel was pointed at the driver side fender and then lifted it out vs pulling the harmonic balancer. Same process for installing the motor as well.. loosen the trans Mount from the frame it’ll make reinstalling/disconnecting easier vs fighting it. I only run 93 octane, I found a couple stations here in Michigan mixing E85 with slack tanks of 87 and 89 to “get by” on a cheap side when fuel is way high in price…. And the sticker saying fuel mix with ethanol no more than 15%…. 15% is the suggested lowest amount up to 21-22% ethanol can be mixed into the fuel. I found a station here in my local town with an alcohol mix of 80% in the 87 octane pump. Saw it on my scanner and once we dropped 15 gallons of 90 octane (rec fuel) it instantly dropped to 27%. It’s all rigged…..
My wife and I have been married 42 years, when we first got married she wanted me to shave my mustache, I did and she said grow it back and don’t never shave it again
I worked in the plant that made the lifters and the deactivation parts. It’s a fubar from the beginning
Hey Nick I love how you are embracing metric.
Next leg arms will be talking tonnes per hectare and big brute will be calibrated in bar pressure and litres per hectare.
the australians, new zealanders, are well adapted to the metric, only the USA and the british are left ! The British we Europeans have let them mourn in their island!! because they are original.-odd. of France
😂 I thought that I was the only person that broke electric connectors!
This vid made me feel a LOT better.
Love ya, brother.
It is so nice to see a video from you guys sorry about your pickup Nick I hope you can get it put back together and running strong again
Probably why my dad is so fond of his Tritan V10 and wont sell and get a new truck; 08 F250. Mom gets a new F150 every year used to get Eco boost but the turbos go around 100,000 miles so he now just gets her the normal flexfuel. But for him he is just happy with his V10 08 F250.
08:44 - "all to save half a gallon a mile". If that engine can save four pints of fuel every mile then it has terrible fuel mileage to start with, either that or the easiest way to fill the tank is to just drive it a few miles 😉
But, as I'm not a total pedant, I realise you meant 'half a mile per gallon' and I totally agree, that is not worth destroying an engine for.
I’m a Toyota guy and almost bought a 6.2 gmc last month but I remembered this issue from your first video. Came to my senses.
I have an old 1500HD, 6.0L and 4L80E, the old trucks that are absolutely junk and somehow end up running around 300K miles before dying, I think I'm going to rebuild that truck and keep it, it's been deserving some love, especially with the price of new trucks
Hey guys, I've said it before and I'll say it again, if you buy Fords you don't have this problem. Ford has a better idea, they make trucks that last. Best selling truck for 45 years running and then some. Blessings always enjoy your videos! Wish they could come out more often.
Have a 6.2 in my ‘10 Yukon XL. Pulled a camper w/ it from NC to MT when we moved no problem. It leaks oil but it’s solid. Sad to hear yours have that issue.
Good video Nick, nice to see you. I hear you on them electrical connections Now you got me worried about my Silverado.
My 2018 6.2 made it 227k before I traded it in with zero problems and I was the original owner. Every day I expected it to happen but it didn’t. 2/2022 I ordered and purchased a brand new trail boss Chevrolet with a 6.2. That truck right now has 81,000 miles on it since new. But I purchased the programmer with it, the one where you go in and turn all of that stuff off and your auto start and stop also. Love that 6.2. By the way I also sent the ECM off to have it programmed. She will run.
I remember Dad's 68 F 100, had a 360 in it, no power brakes no sensors no nothing. You could actually see the sparkplugs
Nick, Excellent video, Praise God the engine block is not scrap. Looking forward to part two. God Bless
All ready waiting for part 2 , God bless your famiies ..I hope the snow orovides enough moisture for better yields this season
Awesome video I'm glad you picked up a carma to record the every day life on a farm thank you Nick
I got a 6.7 in my DWODGe ,new word for me,heard it some place outa Montana, haven’t had problems, it a 08 dually.
Little piece 9f advice i learned from a gm master mechanic, the hoods have a service mode on these trucks. You pull the small bolt and it allows them to swing vertically and then it creates so much more room to put a hoist in there.
I love seeing an engine fresh back from the shop. They're so pretty 😍 Only wish they'd stay that way 😅😊
Looking forward to the next video! It's great to see the Littles & Mrs. Welker, even if it was 6 mos. ago! God bless
Sounds like a job for Vice Grip Garage Fellas that going to town rig needs the ol Italian tune up
Sure miss the old small and large block engines of the past that were simple to fix on the roadside and didn't require 200 sensors and a computer and an I T guy to diagnose them. Be safe and have fun
Nick, I know your frustration. I've been waiting for a year to get pistons for my LLY Duramax in my '05 GMC 2500. Good luck with your new engine!
Thank you for the information on the GMC 6.2 engine. I was seriously considering purchasing a new 1 ton dually with this engine. I believe I will take a different route now. Long term subscriber.
I love your videos of your wrenching on stuff. So down and dirty and real about everything.
I had a 17' silverado with the 5.3 in it, miss that truck more than anything. Unfortunately mine broke a lifter collapsed another and bent some pushrods all because of the afm lifters... wish i still had it. Ive also heard from others that have the 6.2 you have to run 93 or premium gas or you get pinging and detonation bad fuel mileage and loss of power. Glad to see you got it back up n goin again
Plenty of 6.2s and 6.0s out here in Australia. 🇦🇺🇦🇺🇦🇺
Gotta love the dod system. My 5.3 lost a lifter, killed the cam, oil pump, and at least 1rod bearing. In the process of a rebuild like you. Hope yours goes well
🔥with all them new parts, check fuel rail pressure and injectors.. specially the injector on cylinder that had bad piston .. right on nick happy fir ya man, I had 07 5.3 and did the amf delete kit and cam, def opened up the power and reliability 🔥👊🔥🔨⚙️🏍
Excellent video, informative, entertaining, and a lot of other complimentary words I cannot think of right now.
But how blessed you are to be able to do all that work yourself!
Great Video. I've got a 2016 with a 5.3. Same type of motor. Didn't know this was a thing
If it was me, I'd have a old coffee can half full of 'extra' bolts, nuts, and what not left over after reassembly. And wondering if they were important.
I feel your pain. I replaced an ecoboost in my 2011 F150 recently. It had 190k on the clock. It took 8 months and $11,000 to get a reman from Ford. I have 2 of my company Rams down with the top ends destroyed. 180k-195k miles. Just gonna sell the carcasses to someone.
Had a friend’s Yukon Denali 6.2l go down last year with bent push rod. Only had 6K miles on it. Took 4 months to get GM to fix it under warranty.
I just purchased 4 new 2023 rangers today for my employees. Vehicles are not cheap but are a necessity for my business.
GM know what they are doing....they like selling lots of engines and transmissions replacements. Good thing Welkers have Nick who is the real brains of the whole operation.
....don't tell anyone but the wives are the real brains around here.... 🤫
Thanks for the update Nick. Cant wait for the next one.
awesome video. Engine looks great. Thank you
I remember when she Rose was born. Man time flies.
Great video, Nike. Always good get the pickups going.
Nick, I know the pain with those motors. Mine didn't get that bad before I got rid of it, luckily. I managed to drive it almost completely dry of oil before I realized what was happening and what caused it. I did everything short of putting new rings and motor in it. It got so bad before I got rid of it, that I couldn't drive a half hour without it losing a quart of oil. Best of luck to you in your search and rebuild.
Parts have been a headache to get for pretty much everything. Glad to hear you can finally get your truck back together.
Oil maintenance is critical on those I have one with around 100,000 love it I took a road trip and got 30 mph!
I have been a GM fan since my first new car in 1973. My 2016 5.3 Suburban was the first time I started doubting their quality. At the first oil change their was some kind of bulletins about porous cylinder heads. 1 had to be replaced. At 30,000 miles GM put in a new crate engine, I was smelling coolant in the exhaust. That one is ok now with another 30,000 miles. I added a 2020 GMC AT4 6.2 L to my fleet. 6.2 is fun to drive but I always use high test gasoline.
Good luck with the truck. The kids were precious.
I have driven them all, even a Kenworth W900, different job. When I quit the long highway runs, +80 k miles a year, I went from a GMC diesel pickup, to a Dodge Ram 5.7 Hemi, I don't think I will ever go back. My friend, the GM sales manager, is still a friend.👍😎
Thanks for another great video. It was interesting and enjoyable.
Thanks for telling us all about the 6.2 engine problems. I feel kind of dumb. I was totally unaware of this. Wow. Don’t want one of those. Sounds like GM has some really big engine design problems.
Thanks nick for clueing us in. Like I said, I was not aware of this.
Feel bad you have to wait all these months for your engine. At least it will be a regular engine without the new design issues.
Glad you finally got it back.
Now the hard part of getting it back together again. Know you and the family will get it back together and going again.
Nice truck you have there. Will be great once again with the new regular engine.
Thanks Nick for all of this information on the 6.2 engine.
Thanks for everything.
The Iowa Farm Boy.
Honestly pretty much everything he said in this video was wrong.
Roller lifters by meling, comp cam, 30 over, 9.5 to l
I have a 2006 2500HD with a 6.0. It was one of the last few before that fuel management junk. It’s been a good one.
The 2500 and 3500's never had d.o.d/afm so the 6.0 is actually got better around 2011/12 with more power and is good through 2019 when they switched to the 6.6 gas which also doesn't have it.
And once you get that nice fancy engine, put back in take that K&N filter and throw it as far away as you can and put a good quality regular one back on it. Those stupid things have leaked more dust into engines.
I am so happy that you got your engine back for your GMC truck
Sorry for anyone confused… its not ".5 gallon a mile savings" its 1/2 of gallon "per" mile so 16 miles "per" gallon vs 16.5 "per" gallon savings. Meaning you would save 15 cents a mile. If the motor cost 10k he’d have to drive 66,667 miles in order to break even on gas savings ALONE.
My lt83 has been locked into v8 mood for the last 44000 works flawless
The new long block looks super nice! Hope it run as good as it looks.
I work for a dealership and same thing wait along time on parts. We usually pull the cab off the frame to change them so much easier
WOW - what a story. Here in the colder parts of Aus where I live on the Monaro Plain, the older 2008 -2020 Mitsubishi Pajero is popular on farms and the DID 3.2L diesel is rock solid, until odd gremlins akin to yours, surface. My 2008 model is a rockstar for a daily drive and towing machinery around the yard - I did have to seek a techie to rectify an Exhaust Gas blockage and now all is sweet. While I love V8 power, I am guessing motoring history in US leans towards V8 versus straight 4.
Rockin the Deboss garage shirt… love Rich’s channel
ahh, that great GM feeling. We had to put a new transmission in ours at 150k. junk.
can't wait to see the rebuild.
Change the camshaft and lifter roller rockers etc to towing cam or extreme 4x4 low end power ones i just got done doing mine and my sister in-law has a 6.2 Tahoe but it's got a chatter good luck with it hopefully it lasts forever
I love the question your daughter asked, and your answer was equally great.
I saw 2 -- 6.2L at the scrap yard a few weeks back (here in Canada there are quite a few around)
Are they the L86? The older 6.2 engines are common but anything 2014 and on is hard to get. Especially pistons too.
Cool video Nick!
Oh boy, I can't wait to see it run. Great Video...
My 6.0 did the exact same thing at 135,000 miles! Exact same thing!
Yeah, got 265k on my 00 Silverado 5.3l, engine and trans original, and it still runs good (It was the only one that would start among my family members in the area during that arctic blast that ravaged Texas a few years ago (live in Kansas). It still runs great, so until it goes belly up, its my daily driver.
The older 5.3 is likely to outlast the body.
@Badger Pa so true. Rockers are pretty rusty, and wheel wells are starting to rust through, but it hasn't failed me yet
I use bg 44k on my dgi car, and it keeps the carbon from building up. Liquid molly has and additive as well that helps. Amazon sells both. I use the gas additive, as well as the stuff you run through your engine when doing an oil change, work's really well. The stuff is a little pricey, but it's cheaper than carbon building up, and not allowing the valve's to close all the way, and then the varnish that builds up in the engine clogging thing's up. They sell connectors at rock auto, and on amazon for most stuff you'd need. All the plastic they use in these engine's is rediculous, because it gets brittle after a few year's and then cracks, or the o rings turn to plastic and leak. I save every connector if scraping a car, helped me with my dad's truck i inherited after he passed away last year. I scrapped a mercury milan for a friend eight year's ago, and the connectors work for the ford ranger, which has lower miles, little rust because it came from south carolina before he got it. I just changed all the hoses, power steering lines, and just did the maintenance thing's for an older truck, and hopefully it will last me awhile. G-d bless, and glad you were able to get a bullet proof engine build.
We've got a six litre in a Holden commodore wagon here in Australia.
Done 350,000 kms and still goes strong. It also has AFM. Always ran it on 91 octane.
GMH or GM as you guys no it has said no more parts for Holden into Australia from 2024.
That's going to be bad.
Looks like things are looking up. BTW, when that door doesn’t open…look up.
Nick, after you get your engine fixed tune that 6.2 for more power. I have an 08 Silverado 5.3 and have mine tuned to turn off the afm dod. That was 150,000 miles. Now have 230,000 and she still runs like a top.
What tuner did you use?
@@greendeere777 had someone custom tune it. HP Tuners is the program they use
Watching a Welker video with crickets in the background while sitting inside with a blizzard outhere in winkler manitoba today 🤣
Played in a hockey tournament up there a while back with a MN select team. Made to the semi's with 8 players. Everyone else had broken collar bones. You boys hit hard.
@Hawks 22 that we do and a lot of guys are farm boys as well that like to play hockey 🤷🏻♂️🤭
@Hawks 22 I shouldn't be laughing but maybe that's why gordie Howe and Patrick Marleau were able to play in the nhl hockey for so long because of being country farm boys 🤭🤣
Best decision you will ever make. I have a 2016 with the 5.3ltr. It dropped a lifter at 50k miles. Rebuilt the motor and delete all that junk GM thought was such a good idea!😂
The reason GM did the AFM is because of the EPA regulations saying the car companies need to get better fuel economy. Ford went with the turbo “Eco Boost” and GM went with the AFM. I have a 5.3L and I only run premium fuel. It idles smoother and gets better gas milage. I also make sure the premium doesn’t have ethanol in it because some companies post that the premium has ethanol in it.
Now all you have to do is remember where every hose, line and wire connector goes! Have fun!!
Thank goodness for cell phone cameras to keep a record of all of that stuff. I remember, back in the day, when we used a polaroid camera to record disassemblies.
@@chrisallen2005 and colour code as much as you can
Hey Rick! loved the video, DOD still in it, eh? Is the AFM still "active" I thought there was a way to reprogram the PCM/ECM to disable Active Fuel Management? Anytime I run across the 'new' features like "Auto Start/Stop", I find ways to permanently disabling them. I have a 2001 Chevy with a Vortec with 268,000 miles.. the only thing I HAD to do, is replace the valve springs because they were worn out and weak.
While I did that, I refreshed/replaced other things, water pump/thermostat, EGR Valve and piping, Starter motor.. and slapped new springs and joints on the front end. Standard Maintenance like fluid and oil/changes, make them last a long time.. but the 'new' electronic stuff like AFM/DOD and all the Auto/Start garbage, is just that GARBAGE. So.. I am collecting parts and building another Vortec to replace the EcoTec in another car. Full "New Tec" delete...
There's a video out on using a zip tie to refasten broken electrical plugs. I'll see if I can find it.
I'm surprised you haven't disabled the eco mode. Also change the slippage for the transmission.. it's another thing they've made to fail with the computers help.
I've got the same truck, highly recommended to disable at least those two things
Got a 2019 5.3, how did you disable the AFM and Trans ordeals?
@@greendeere777 went to local transmission company & they re-wrote the code (my truck is a 2017 sierra kodiak 5.3 and have had it since 2018 working everyday), disabled eco mode, transmission disk slippage & gave me more torque one or two more things but i can't recall what they are.
fuel milleage actually went up, i get a weeks fuel hauling a mini excavator around, small tractor, materials. it's a work horse!
Sorry you had so much trouble with the 6.3, but looks like your on the road to recovery. We have a 09 5.3 and one lifter went bad. Fortunately, only drove about 30 miles motor was ok except the lifter and the cam. Replaced the cam with a performance cam along with all new lifters, new oil performance oil pump, deleted the AFM, replaced the timing chain and gears to a three bolt gears, and plugged the oil passage at the bottom of the block to keep oil from spraying into the bottom of the last cylinders. Oil pressure is now usually around 70 psi warm and the motor will literally plant you into the seat.
my truck ('02 chevy silverado 1500) has a few cranks short of 345,000 miles and is on it's second "heart" (roughly 100,000 miles on the current block) and as far as I know, it's the original transmission from the factory. I wonder...
Welker Farms come to michigan there dime a dozen here! 6.2 ltr
Who in Gt Falls did the work to your engine? Happy you got it back.
We have a 2017 Silverado with a 5.3 that was towed in to the shop I work at. He drove it with the oil pressure light on and locked it up. No reman engine available from GM or Jasper for it.
you guys seeding yet, we aren't it southern Alberta Canada looks like were at least a week out, last year at this time we would of been seeding for a week already.
Awesome video thanks for sharing very unfortunate that your engine blew up
How is the moisture looking
I did the DOD delete on my 2013 5.3 before I had a lifter collapse on me just because I know how notorious they are. Easy to do as well as long as you catch it early.
When I saw Leg Arms in the engine bay, I thought for sure he was just going to grab the motor and pull it out for Nick.
I bought a module to omit that GM fuel saving junk on my 5.3 and saved my engine. Too bad you have to go through this.
It’s easier to pull the cab than you think when you have a lift. The air conditioner compressor gets unbolted from the engine, drain radiator, remove hoses and fan, unbolt the master cylinder and leave it hooked up, the it’s a couple of electrical connectors, ground wires, and the e-brake line. Boards on the lift and pull the 6-8 cab bolts an up it goes.
I had to put an engine in my f150 ecoboost and was running into the same issue you can’t get them I was quoted a 15 month waiting period from ford but I did some looking around and found a reman engine from a company in Michigan
makes me thankful for my pre 2007.5 5.3l
Great video!
Did a dod delete on my 6.0, did all the supporting mods and a rcr little lunati cam..in my G8, 428hp to the wheels after a dyno tune
Very good Video 👍
