What do you think is the best engine ever made?
Ford 289
2 easy choices Cummins 5.9 and 6.0 ls Chevy non direct injection non dod
7.3. May not have been the biggest, most horsepower, but man she never broke
Cummin😮
Vortec 5.3 engines typically are solid engines. With that said ppl say Zach aka mn millenial farmer has battery bermuda triangle now it seems you guys have engine bermuda triangle lately.
That sure was nice of Tony’s family to let you use their vehicle. That’s what nice about knowing good people. God bless
Tony Fast and his family are excellent people. Just great Americans.
Fast Ag is woefully undersubscribed on TH-cam. Amazing people with amazing content. They definitely deserve a watch.
Just subscribed ...
They deserve a watch and a subscribe!
Used to be subscribed til he started letting his farm hand do most of the videos
@@koryleague8833 So why are you subscribed to Welker Farms?
Bob doesn't show up and do much of the videos ..
@@bobbyt2657 your comment makes no sense
Incredibly kind gesture by Tony’s parents to lend their vehicle so you could continue on with your Christmas trip.
They were amazing
The appreciation that you shared for the Fast family made the whole video ❤. That’s what separates farmers from most any other profession is that when there’s a problem, you can count on another farmer for help.
I'm so thankful I've kept my 02 Silverado Z-71 4×4. Just a simple 5.3 engine, no cylinder delete. I think that's why I'm up to 325,000 miles, original engine and transmission. Drive train has never been out of the truck. I keep all the maintenance completely up to date. Still purring like a kitten. There's quite a bit of rust, and lots of scrapes, scratches, and some dents. It's worked very hard during its lifetime. Plenty of room, very comfortable, and all the options still work, even the power mirrors. Probably have spent more money on it than it's worth, but I love the old girl and I'll keep her rather than get something newer and experience the problems.
Hard to hurt anything when it's making 175 hp at the tires, and that's honestly probably being a little generous.
When Nick came into the shop and started laughing, I just about lost it!!! Lol.
(because he knows exactly how that feels).
Tony fast is one of the good guys hard to find now a days and tim is ace that bloke knows his stuff your very lucky bugger having people like that round you poor old gmc nick clean the shop
A quick tip for you. Pull the rear tires on the lift and you can lower the car about another 6 inches. It really helps us short guys.
Good advice i only 5'5" i dont a lift but i do use floor jacks
I absolutely love watching you work on engines , my husband would work on them and I would help him. He passed away in 2004 and I have his 1968 Pontiac Firebirds’s 400 convertible and I can’t bring myself to work on it without him . Thank you for letting me watch you.
Sorry your husband is no longer around. Happy that you made good memories with him. Our wives are not interested in working on engines but they do love when the engines run so we gotta keep them going! Thanks for watching.
It's still blows my mind that you go to Buffalo NY my home city. I hope you take time to see some of our agriculture out here when you have a chance. Hope you didn't get stuck in the snow storms last week
You're so blessed to be a part of rural America where folks that need help get unbelievable help. Tony does have outstanding content along with the Welker family. Keep it up as it is really appreciated!
Scott that’s what friends do for each other. Tony’s. One cool dude.
His family are awesome.
Tim is. Is cool as cucumber. And funny as hell. And also a great asset to Fast Ag period.
It's actually pretty easy to change valve springs. Get a adapter to put air pressure in the cylinder and they make a tool to compress the valve spring.
You're very fortunate to have a shop and some knowledge of what you are doing. Your attitude is positive and your family supports you. God Bless
Dang that's a tough break!! Good to know that there is still good folks out there to help out like Fast did 👍
Tony and his family are awesome, Just like the Welker's! Montanans at the finest and true Americans!
My grandson bought a 2013 Silverado last fall with the 5.3 in it and 130,000 miles. He drove it home and 2 days later, it started misfiring and knocking. Even though there was no warrantee, the dealer said he would take a look at it. Sure enough, because of the Active Fuel Management system, it flattened the cam on #6 and wouldn't open the valves. To the dealer's credit, they said they would put a used 5.3 in it with similar mileage. They got that one in and it had the same problem. So here comes engine #3. It worked. Since then, my grandson has put in the module that shuts down the AFM. He wanted to put in the different oil pump but the dealer would not stand behind the engine then. So far so good.
Fast Ag should have a million subscribers, a very interesting channel . Very professional outfit
I had a 08 Yukon Denali AWD that I loved. It had the stupid VVT setup. I deleted that when I put a cam and supercharger on it. Ran like a champ until I traded it. I was lucky it didn't have DOD. I think that was around the time that junk started getting introduced. You will have an extremely reliable vehicle once it's back together. Hang in there!
The one good thing about this 'mess' is that you have an enclosed shop, lots of tools and, at this time of the year, not too much going on with the farming business. I was a 'dyed in the wool' guy until the 2000s when I got my first Toyota. They have run VERY well for me. Any more though, I think I would go with a Cummins Diesel.
My buddy had a suburban with a 5.3 that detonated at 85k miles. He paid a shop to install a remanufactured 5.3 purchased through advanced auto part. It lasted 800 miles and blew up. They replaced it and that engine lasted 100 miles. The remanufacturer tried to bail and not warranty the second engine saying metal must be in the oil cooler. Shop verified everything had been replaced with new parts and sent 2nd engine back so it could be examined. After a couple months they sent a 3rd engine and it run perfectly. My buddy was without his vehicle for one year and cost him over $10k in repairs. He sold it a month later eventhough it ran perfect. Was scared it might blow up again. Total nightmare due to gm gas saving device junk.
There are better options folks than these GM nightmares.
Don't blame GM, it's the Feds that are making the MPG requirements. Now you get a small 4 or 6 cyl with a turbo. I remember when a turbo was "racing equipment" and your insurance company would cancel your policy if they found out you had one.
@@randyb1890 GM is the problem at this point. They have been making DOD for 18 model years and it’s still broken. Other manufactures are not having these issues, at all.
Hey Scott I feel your pain brother, I just had the head gasket, timing chain an timing chain tensioner an 1 cracked manifold repaired on my 01 jeep grand Cherokee limited 4.7l, thanks for sharing
It's absolutely rediculous how many sensors an vacuum lines vehicles have nowadays, the smallest things like a vacuum leak can hault the vehicle, the vehicle manufacturers make these new cars nowadays so complicated that you have to take it to a shop to get it fixed because it might need a special computer or some kind of specialized tool or something
This is why I still have a 7.3 PS 1 ton 4x4 and an F150 300ci straight 6 extended cab for light chores. 7.3 has had 2 cam position sensors at $25 ea and a couple o rings in the injector oil lines. Wife runs a 2009 Tundra 5.7 L made in Texas and it has been bullet proof as well. Just put the second replacement battery in it and an AC compressor last summer. AC repair parts were less than $300 and I was the labor. Not bad for 14 years.
I have owned several 5.7 Toyota’s, what an engine! I don’t think another V8 touches it for power and durability.
I had a 300 in my old van. It had an interesting habit of starting, as soon as the key was in the on position. What was happening, is when it was turned off, it still had some fuel in the cylinder. Turning on the key, would fire the plug in the cylinder next to fire, igniting the fuel, and turning over the engine. GM researched this years ago with a starterless engine. Just fire the injector on the cylinder on the power stroke, fire the plug, and the engine would start.
Loved Nick's laughter, ya know he's been there! Great to see the brotherly love and humor! Awesome of Tony's parents to lend their SUV! They are good people too! God bless!
"Ain't got no gas in it."
Great to have friends like the Fast family!
Stinks to have to fix a motor like this, but you'll get it done.
Nick! Clean the shop!
GM guy here too! 1976 Pontiac Trans Am, 10 years 235,000 miles. 1985 S-10 Blazer 14 years 244,000 miles 1999 Suburban 16 years 385,500 miles 2016 Silverado 1500 7 years 129,000 miles Closing in on my personal Million Miles Driven, all in quality GM products. Great work guys!
Over 4 million here. 1 ford cabover 3 freightliners 6 Pete's 2 kw's and 4 Volvo's. Volvo definitely the most trouble free
Them old engines were good
The new ones are junk
Especially this variable crap
You'll never get that many miles on the new stuff.
New GM trucks are terrible! I use to own nothing but GM. Not anymore
Best intro clip you guys have made. That old Dodge spinning the tires and driving over that drum really made me laugh.
Scott, You have a great attitude and patience. Good luck.
So sorry this happened to you. I pray that God's favor be upon you and this trial becomes a great testimony!
Who needs Facebook, Instagram, or TikTok when you have this wonderful outlet called TH-cam!
That is why my 98 Toyota Hilux diesel is never leaving, that thing will do a million km and still run like new.
Scott, in this engine both the intake and exhaust valves are hollow. The exhaust is sodium filled to aid in the heat transfer away from the seat area. The intake valve is hollow solely for the weight advantage.
Interesting.
Tough luck Nick did a good job on the shop cleanup!
I'm a big GM fan also. 2020 Silverado with 8L90 trans was chattering. Read about updated trans fluid in a blue label bottle and it solved the problem. At least for one week . Find out if yours needs it. Full flush 11.4 quarts.
I’m not surprised at all that Mr & Mrs Fast lent you their car, just like your family, the Fasts are a very kind Christian family. If the circumstances were switched, you would’ve done the same. A lesson to everyone about kindness in the time of need.
13:31 Leg Arms' comment about "gotta have the piston at TDC" and Nick adding, "- to keep the valve from falling inside" brings to mind a trick used by small engine mechanics - which is to stuff the rope from the pull starter into the spark plug hole and raise the piston. The bunched up rope will hold the valve shut without harming anything.
If we have to swap valve springs when the head is on the car, we feed shop air with a hose through the spark plug hole.
Every gm motor I have owned after the tbi\vortec era has eaten my lunch. I feel ya bud.
I disabled the variable cylinder management system last year on our 2015 honda odyssey. Just replaced the alternator, which oil leaked onto it, and fixed the oil leak. No more engine light. It so satisfying to do the work your self and how much money you save.
So many engine problems for your guys. Ugh. At least you are mechanically able. Hope for the best. And good luck also getting the Big Bud 6 Series ready for planting. I know you planned some major work on her too.
Don't fret, I fried my 5.4 3V triton with the janky timing setup that is so crucially oil pressure dependent about 10 years ago (2004 MY FX4 bought brand spankin' new) and bought a remanufactured to keep it. Yeah, the truck wasn't worth what the engine cost at that time, but living in the south it's basically rust free, and 8K vs 40K for new made it an easy decision. Truck is still with me and no longer a daily driver, runs great, burns a lot of gas when driven, needs paint next.
I'm sorry for your breakdown Scott. You're right. NOBODY makes a reliable drive train anymore.
I have had very good luck with V8 Toyota trucks and landcruisers. So far Tundra 4.7 372k, Tundra 5.7 280k, 100 series Land Cruiser 282k, 100 series Landcruiser 255k, 200 Series Land Cruiser 110k. Just phenomenal machines.
ive never had an issue with any ford drivetrains over many hundreds of thousands of miles since 2012 on multiple ford vehicles
@@hokie9910 What about American cars from the 50s, 60s, and early 70s?
@@CJColvin They we’re simple machines but back then most people thought a car hit 100k miles it was ready for the crusher.
@@hokie9910 True but some people still have em and fixed em up.
My brother just redid his son in laws 2016 Dodge hemi. What a disaster. One of the roller lifters cracked the roller, dumped the needle bearings and rattled line crazy. The heads and block OK. Took four months to gather all the parts to put it back together. Wonderful story about acts of kindness. Special people!😊
100% agree with you on your thoughts of new vehicles. Quality just isn't there anymore. Don't get me started on the price.
No longer built to last, built to sell more
Just a suggestion,you may want to check and see there is some short of recall or history of this happening to this engine.
Great video Scott. So sorry for the bad luck. But good luck on getting it all back together.
You guys impress me so much by how you just dig into stuff. God bless!
Sorry that happened to you Scott...... unfortunately...... it's a long process to fix it and do it right... no question you'll get it done
The flash light antics made this video funny. Nick being a brother! Not only him stand off on the side not helping, BUT giving input on engine build he's not working on.
We love each other 😁
The inside joke is Nick went through the exact same thing a year ago with his 6.2. So him laughing at Leg Arms is really laughing at himself.
JEGS is having a sale on 6.2 long block crate motors - ships tomorrow. Not that difficult if you want to solve the problem with a long block.
Only problem is by the time They put this out they’ve already doing something
Out of curiosity, I checked the Jegs website. Those engines have a ship date of 2/28.
I drove a chevy 2500 with a 6.2, great truck, good acceleration, good towing - hauling 12k generator. We did have a few trucks with this problem though. Luckily they were fleet trucks and I didn't have to deal with the aftermath.
Awesome content. I have 08 denali with DOD. Scares me everytime I think that system engages
Thank God you and your family made it through safely
Scott, I had 2 valves drop on an engine and am currently rebuilding it. 1 valve was stuck in the piston and the other was wedged in the head. My head had alot more damage to it than yours, but my machine shop was able to locate someone to weld up the damage and reshape the chamber.
You are so fortunate that projects like this come along during your slow season so that you don't have too much time on your hands leading you to getting into non productive mischief.
LOL, you'll have to try to get the wife to stop pulling hole shots and hot-rodding the family vehicle 🤣. Nice to have trustworthy reliable friends. Tony is a genuine good guy all around. Glad you and your family were able to enjoy a family trip together, planting season is just around the corner.........
My sons 5.3 did the same thing his mechanic told him EPA is looking to make it illegal to delete dod systems under federal @ntipollution laws. More government over reach! Really enjoy your families content, hope the rebuild goes smoothly.
Exactly mate, majority of the government that created this is mostly the evil Democrats 😈
Other side of the coin on new vehicles. Couple years ago I had a timing chain failure that bent and broke a set of valves in one cylinder in my 2011 Prius. One new piston and rings, two valves, and a timing chain, and the car was back running. That occurred at 250k miles, I’m now pushing 290k. My point being there are manufacturers that still build quality equipment!!!
I think you and I are the lone soldiers on here begging people to try Toyota or Lexus. I left GM and Ford years ago for Toyota products and have not looked back. My stress level and pocket book are much much happier.
Simply amazing. You guys never disappoint me. Most people would have just sat down and cried and pushed the vehicle off a cliff somewhere. But not you guys. Thanks for sharing with us.
Nick is a very helpful cameraman. And totally not annoying. And he's definitely not messing with his brother... 😂😁😜
Hey Scott AKA Leg arms if they can't fix that cylinder wall see if junkyards may have one check around
If you have to do Nicks springs, make an adapter that screws into to the plug hole and has a male air coupler. Put air pressure into it. An old time trick used when replacing valve seals.
Do you think too dead center is enough or will it be too difficult to lift the valve high enough to put the retainer on? I've heard the air pressure trick, definitely will try it!
@@WelkerFarms TDC may not be high enough to keep the valve up far enough to get the spring retainer and keepers back in place. Using 150 lbs of air pressure in the cylinder is more than enough to keep the valve seated while you work
@@WelkerFarms If you want to use the TDC metthod, I've used something like braided rope/paracord and pushed it into the cylinder via the spark plug hole. That way when you raise the piston to TDC the rope fills in the void and holds the valve completely closed. I've used both air and rope methods successfully.
Some great ideas, I like the rope and air. Just need to get the spring compression tool.
With the air pressure hold, you also need to put a socket on the end of the crank and brace a break over bar against the frame or something to hold the crank in one place. The reason is if you don't get the motor EXACTLY at TDC on the cylinder you are working on, the air hold will spin the crank over. Sometimes it will hold in place at TDC for several minutes, but then all at once it will spin - usually at the worst possible moment.
That is why the rope trick is usually safer, but more hassle to do. The easiest method is to feed a bunch of rope in with the cylinder part way down in the stroke, then rotate the crank towards TDC until it stops - forcing the rope up against both valves.
OBTW, racers repair (tig weld) LS heads all the time with far worse damage that you have on yours. A decent pro welder can fix most damage for you, they have the experience to weld up the head without porosity problems. Then machine as normal.
Bless you guys...Love to hear the brotherly love u are expressing:)
I work for a chevy dealer in the parts department and its crazy how bad the fuel manager system is and how much chaos it makes when something breaks.
If there is something you need or help with id be happy to help.
The entire vehicle shook? That’s the Great GM Feeling we’ve heard so much about! 😵💫
I had a Ford that lived up to its name. Fixed Or Repaired Daily. Had it only to 40k miles before got rid of it because it spent more time at the dealership than the road.
Leg arm I feel your pain. God bless you and your family
Scott, 5’ 10” is not short. Good luck on the rebuild!
Hi Scott. You guys always keep such a positive attitude in the face of all obstacles you come upon. That is just great and uplifting to see. I hope it works out to be the least costly option for you. You are right about the state of auto manufacture and repair in our current times. I drive a 15 year old car that has only the minimum of electronics on it, I can work on it myself or if I do need to take it to a shop, repairs are reasonable. I don't even want something newer. Thanks for sharing your unfortunate engine problem with us. The situation could have been much worst and thankfully, was not.
My '07 Silverado 5.3L experienced a DoD failure at 232k miles. One of the lifters collapsed for cylinder deactivation and would not release. I got a special punch that is designed to allow the lifter to release when it is hit just right. I did that, it worked, and I put a cylinder deactivation override device on it and broke off some parts of the VLOM gasket so it cannot build oil pressure and activate the DoD. It's been running great for 3,000 miles, but this truck doesn't get driven that much anymore. It's a chore truck.
I have an 08 Burning loss of oil. For 2000 and some Repairs it has been good for a year.
Glad to see some great hospitality! Also, not sure if anyone has mentioned this. Heard a lot of horror stories on the torque converters on these. Check out the Silverado Sierra forums. Since the engine is out might be worth upgrading to a better torque converter without the thin walls. How many miles are on that Yukon? I have a 15’ Sierra with 141k. Considering my options incase of this issue. Thanks!
Best vehicle is the one you’re comfortable with working on yourself! They all break. God bless Welkers.
Thank you Scott...enjoyed the demo of the rusty drum!
Dad's 6.2 was good till he hit 200k now it seems to drop a valve seat every year. And runs exactly how you described every time it does it
Cylinder deactivation has caused huge problems with many 6.2l
Exactly mate and thats why I refuse to get any modern GM vehicle period.
Just worked on a 2015 Yukon XL with the 6.2 that ate a cam. I noticed the cost of a new cylinder head from the dealer was less than $300 complete with valves so that could be a cheaper option than working your existing head. It’s also very common for piston material and other debris to get sucked up into the intake manifold and the material goes unnoticed until you and install it on your new engine so it’s there is a high probability you’ll need a new intake manifold as well. Good luck with your build and glad to hear your trip ended safely.
To change the springs without pulling the heads you need to get an compressed air adapter that fits into sparkplug hole and use compressed air to keep the valve up while you change the springs.
I’m sorry Scott you and your family have to deal with this. I prefer GM, one of my brothers is a Ford nut and the other is a Ram fan. You are correct. They all have their expensive issues. Oh I wish I had my 64, 65 or 68 C20’s back.
Wife drives a 2021 Denali and it had 9k miles and a similar situation happened to us heading down the interstate. Lost power, weird engine noise, barely made it off the interstate. Turns out it was bent push rods. The GM tech said it was a common issue over a few of the year models on the 6.2 and some of the 5.3 engines. Faulty spring retainers or lifters is what we were told. Frustrating to say the least.
That same thing happened to my 07 5.3L at 167K. Still a good vehicle
Good grief, how can GM who brought us the small block V8 those many years ago not figure this out. They have been having these problems now for 17 years!!!
God bless you all! Make engines great again!
New cam, new lifters, new valley cover, reflash ecm. Did the same on my ‘07.
Replace that torque converter while it’s this fair apart. Another thing that goes bad.
I grew up in a 84' Ram Charger 4x4 with the 360. i loved that thing!
I had an 83 with the 318. No power but It would go anywhere
First I apologize that I’m logged in under my wife’s account. I’m a 27 year GM technician. Watched the video and want to give a heads up on repairing the block. You can have machine shop bore and install larger piston’s from aftermarket companies. But you have to do all cylinders or you will set codes for cylinder balance issue and have an SES light and remote start will be inoperable. GM had a bad batch of valve springs and issue with camshafts. My boss’s truck broke the valve spring and dropped into cylinder like yours. I have a great machine shop to work with that we figured this out with and wanted to pass on. Great video
Appreciate the insight! Definitely will have all cylinders bored the same and new pistons for all 8. A good machine shop did this to Nick's 6.2 and it is running great! Except it has the old springs still so we will swap those out after learning about the spring issue. Both vehicles are 2015 models.
Amen to the rant around 27 minutes! I hate everything about my '16 Jeep Cherokee that has been nothing but an electrical nightmare.
with that air intake boot like that you should have had a lean code setting because of unmetered air entering system after the mass airflow sensor
I think you could get an engine from an aftermarket company much quicker then through gm , like blue print engines or jegs..
You are probably another winner of the GM DOD failure. I ended up rebuilding the top end of my 2015 Yukon Denali do to a DOD failure. My advice, remove the motor and do it on a stand, I didn’t and would have taken a lot less time had I done so. Good luck
Great video Scott!! Your right...God is good in all things. I just deleted the cylinder deactivation on that engine. Thankfully before damage was done. Your family is a great example of God fearing people working hard. Keep it up!!!
I have an adapter to shut off the active fuel mgmt!! I have a 6.2 high country Silverado!!
Leg Arms please let me know u ordered on of those!!??
Better be nice to that Ram - it beats walking 😜
So nice to see Nick full of sympathy and support , that's not right more like sarcasom and laughter. What a grand gesture of that gentleman to lend you his car so at least you could have your christmas break kind of restores your faith in human kindness
Never fun when the family mobile goes down. Had to rebuild our Suburbans transmission after the torque convertor blew up.
Tony's family sure are nice people. Sickening feeling to see that in your engine hope it is not as bad as it looked. Stretch that sensor, lol, Nick. I agree way too much junk on the vehicles, and it is miserable to get anyone to work on a vehicle around here. Stay safe and healthy.
In January of 2020, I had just got back home from a trip out west to South Dakota, Wyoming, Montana and my 2015 Yukon Denali XL 4WD with 150,000 miles on its 6.2 went south due to the cylinder deactivation garbage. Had it rebuilt and that turned off. I now have 183,000 plus miles on it. Love the vehicle and it will be my last one. I have front leveling kit and 1inch level in the rear. It’s got a cold air intake and I run 305/55/20 Goodyear Wrangler Duratracs on it. This set up has been on it since I bought used in 2016 with about 45,000 miles. It was built in 2014 so I lucked out and got the 6 speed transmission for the switch over to the horrible first generation 8speed transmission…My mileage did not change that much, maybe 1.5 mile per gallon. But it’s straight 8 all the time…Will drive it until Jesus Christ comes back, or until my kids have to take my drivers license away.
Be blessed and be safe….
Brotherly love at it finest!😂😂😂😂
19:06 You can see it's the intake valve (the larger one) which failed (likely due to the intake breathing dirt)- just as Leg Arms had guessed.
Time to drop a LS in there .... Oh wait! I have the best idea to fund this project! Picture this ... a shirt .... that says .... "Never Skip LEGARMS Day" It's perfect. You'll get all the funding you need, and then some!
Love it!
I have always loved GM products. My first car was a 442 Oldsmobile with the 455ci engine. I would give my left n$% to have that car back.
