GM Truck Engine CARNAGE!!

The 2014 GMC Sierra Crank No-Start that we diagnosed last month is back on the road after an engine swap!
Let's see how mad the CARNAGE was, and discuss the ROOT CAUSE of the failure.
Enjoy!

Agreed. Keep it stock and don't beat on it.

[@johnshellenberg1383]

Years ago there was a poor guy at an intersection in a pick up with his hood up and I stopped to see if he needed help. He told me it wouldn't start and he just needed a boost. I turned on his headlamps and they were super bright, then I took a quick look underneath the truck and there was oil and parts of a connecting rod on the ground. "A boost ain't gonna fix this." He was mad I wouldn't boost it even after I tried to show him the "not supposed to be on the outside" part of his engine.

So how many RPMs did you get it up to? Customer - “All of them”

[@SmittySmithsonite]

Holy crap!! The older LS engine's lower ends could take 1,300-1,400 boosted HP before con-rods bent, so it looks like the newer generation of engines aren't as stout. Can't say I'm surprised there. The GM cheapout continues! That said, you can't go changing ANYTHING that affects power output once you've had a dyno tune. All that affects fuel mixture, big time. I wonder if the piston failed first from detonation? The hole in the block tells me the rod catastrophically failed. Either weaker rods, or maybe lack of oiling due to the super high RPM he was at - he could've cavitated the oil pump. We may never know! Great vid, Ivan! Catastrophic failures are always fun to look at when you don't own them, LOL! 😁👍😎

[@RussellBooth1977]

My 5.7 litre Chevrolet LS1 V8 engine in my Holden VY SS Commodore had more power after I picked it up after a registration inspection in December 2019. I had replaced the headers with 1 5/8" primary Diameter Genie tri y headers,2 × 200 cell per inch 2.5 inch catalytic converters & a twin 2.5 inch high flow cat back exhaust system. They secretly snuck it on the car dyno without me knowing,it was a girl who I went to school with who drove it to the dyno tuner. It put out 235 flywheel kilowatts from the Holden factory but it had custom made headers & a twin 2.25" exhaust system & it made about as much power as the 6 litre (L76) powered Holden VZ series 2 & VE series 1 SS Commodores did in 2005-2006 (276 flywheel kilowatts). With the standard 5.7 litre LS1 V8 engine. Now it makes about 300 kilowatts at the flywheel,I had it up to 200 km/h (120 mph) & it started pulling past that Speed as well,it g it there pretty quick as well. Back in 2002 when it was made Holdens special vehicles division also did similar exhaust & tuning mods albeit performed a MAFless tune to remove the restriction from the inlet manifold to get a 285 flywheel kilowatt power output,the compression ratio was also reduced from 10:1 to 9.98:1 in the Holden VY SS Commodore Clubsport R8 back then. It was tuned to run on 95 octane premium unleaded fuel & mine is tuned to run on 94 octane E10 unleaded fuel. In the 6 litre L76 V8 powered cars a larger diameter Corvette MAF sensor was used instead of having a MAFless tune done !

[@frankvucolo6249]

Ivan, thanks so much for the follow up on this truck! Always good when we get a chance to find out what happened.

[@marty0715yt]

Disable rev limiter, disable traction control, disable common sense. Was the owner 17?? If you want high revs get a rotary. Statistics point out that new Viper owners went a short distance before they had a mishap. Can't fix stupid. Can't see cps outout? Can't find cps!!!

[@tonyedwin9042]

Just reading about a shop who replaced a transmission with a dealer supplied unit. They are going through a warranty claim on it now and the dealer wants pictures of the exhaust, data with engine running from the scanner pertaining to egr and fuel pressure. Under hood pictures. No messing around anymore

JBW.....yep, I've installed a couple Jasper engines and trans in customer vehs.....they have a I THINK either 12/12 or 3/36 warranty or something along those lines, BBUUTT.... That warranty is only good for one use. Northstar engine in a Cadi I swapped, it was literally only 1 month old, had catastrophic internal failure, bad bearings. After lots of back-n-forth, they finally sent another engine, again,BUT, as soon as the shop signed for it, the warranty ended. Even w theoretically 11 months left, no more warranty. I'd almost rather buy a good used engine, replace any warn parts and install it!

Love it ! Although I feel bad for that fellow, but we sometimes have to learn the hard way. I had the exact same issue on my 84 GMC. Sadly I blew it up by going into a river that was to deep, after I swapped the engine my friends nicknamed it the Dolphin, which was well deserved. (school of hard knox) We all learned something the hard way right ?

Wow, he detonated that LS good. On a dyno, I believe it is under less load than on the road, and you NEVER disable the limiter or this very well may happen....and it did, nice inspection hole in the block. Ladies and gentlemen, the rods have left the building!

[@404notfound.....]

I tuned the hemi engine on my challenger but set the perimeters although higher still at a safe limit.

[@302vettelife2]

I'd place 85% blame on the tuner. It is NOT easy to grenade an N/A LS engine this bad.

[@bertvisser6423]

I have to agree with you, you can push these engines to well over a 1000HP on stock bottom end. And over revving it would cause valve float long before rod failure. Something not right with the tune for sure.

[@philllsxga.7737]

I have a 2014 Silverado with 135,000 trouble-free miles, I race it in the sand dunes and tow a lot and have not had one problem with the engine.

[@SmittySmithsonite]

I'm thinking GM may have cheaped out on these newer generation engines. Wouldn't shock me - it's a trend that's been happening over 20 model years now with every component. Every year they get worse and worse. The older LS lower ends could take 1,300-1,400 HP before the con rods would bend. Even then, they'd BEND, not shatter into 5 pieces. These were junkyard engines, too! Some already had 200k miles on them! Plenty of KZbin vids out there of a few guys doing this.

[@mikechiodetti4482]

Nice job! I like the external oil cooler AKA the hole-in-the-block! Shotly after I got my 06 Nissan Frontier V6, I wanted a tune for it. Got it, installed it, only used it occasionally, AND it wasn't smog legal ( in California), so I had to remove it when smog testing. THAT GOT OLD EVERY OTHER YEAR, so I removed it a few years ago and it never went back in. Gonna keep it that way! Want lots of power? Buy a (purpose built) Camero, or Mustang , or Charger with the Hellcat engine!

[@curtisj2165]

Why on earth would you remove the rev limiter? It is there for a very good reason

[@dans_Learning_Curve]

A mistake he won't do again! It probably was fine until he changed things after the tune, thus changing the fuel mixture.

[@zx8401ztv]

Well its only a little hole, a bit of tin and some jbweld would fix it :-D The lesson to be learnt is: If you get a little bit extra performance then be happy.

[@kastooMcFry]

Some violence was involved, definitely! Thanks, Ivan.

[@daviddelle774]

My guess is that it wasn't ONLY the tune and it possibility being a little on the lean side. If that were the case, he may have overheated the piston, seized the rings and scored the cylinders. Maybe even burned a hole in a piston because of detonation. My guess is he was playing in the snow, spinning well over the limit and probably hit dry pavement shocking the engine and drive train a few times. Do that a few times and then just that one more time of 9000rpms and she gives up the ghost! It is quite evident that this guy was totally oblivious to the fact that his engine was coming apart while he was doing whatever he was doing. It was broke and he was still "Giving her the beans"! Let's see how long it is before he comes back to have you check out his transmission....?

[@JOHNSUE28]

Yes, David. I would place bet the root cause of this carnage is linked directly to the Owners right foot. And the ability to lie also. And upgrading the power incorrectly. It just makes it more difficult for us professionals.

[@mikefoehr235]

I never change anything unless it is absolutely necessary. With new vehicle and extended warranty, DO NOT want to void the warranty.

[@bernardaflores1720]

He should have install an A/F sensor to monitor the fuel trims. I bet he probably did have some fun on the snow!

[@bigdaddymak1439]

He had to do something crazy because LS motors can take a lot of HP upgrades. Definitely too lean and too much RPM to do that damage

Had the same thing happen I bought a 2004 Silverado with a blown engine. I have no idea how it happened but it had a hole in the exact same place, behind the starter. dissecting the engine it was really clean inside. It broke a connecting rod but no signs of oiling issues. I think it was over revved.

[@killman1971]

The Gen 3 LS engines had problems with the valley mounted knock sensors detecting sudden damaging detonation on the rear 2 cylinders when the rear steam vents ports were plugged (ie blocked off from the factory). Using a junkyard 2 port vent tube with a brass 1/4" tee and proper 1/4" coolant hose will fix the problem. Probably not a bad idea to do the same on a Gen 4 as well.

[@bertvisser6423]

These ls engines are capable of well over a 1000HP on stock bottom end. Which this kid couldn't have made without a turbo or NOS. Definitely something wrong in the tune,and too high rpm would have caused the valves to float,not break a rod like that. I'm suspecting way too much timing set in the tune.

[@billmalec]

@@bertvisser6423 I'm sure they are capable of that hp. But for low long?

[@bertvisser6423]

@@billmalec I personally am helping a drag car with a ls here that is dyno'd at around 950HP to the wheels and he's in his third race season on same engine,hasen't touched it for anything other then oil changed and tweaks. He does about 35 race days a year. This kid only has some small mods,an intake,exhaust and a tune,not even a cam or valve springs(which I would recommend as stock valve springs float little over 6k rpm) so he'd be only pushing maybe 250/280hp to the wheel. With a proper tune it could be his daily driver for many years without exploding.

@@FunnyMuffler I'm referring to overall performance not just horsepower. Lift kits, oversize wheels and tires, cold air intakes, tuning, headers, exhaust do nothing for ride quality, handling, braking or fuel efficiency. AND, an unmodified well maintained vehicle will always have a better resale value than one that's been heavily modified. Nobody else will want to pay for your modifications.
