BURNED Silverado 6.0 LQ4 Engine Teardown! Will I Get A Good Short Block Out Of This?

[@reubensandwich9249]

The top of my wishlist is a teardown of a runaway diesel.

[@b1g_ben-473]

“Externally overheated” nice 👍 😂 keep up the content I’m still waiting on a 3.6 pentastar yo

[@I_Do_Cars]

I have a core coming back soon!

[@b1g_ben-473]

Right on im getting anxious buddy lol

[@tommywvk]

Hell yeah now that's a good suggestion

[@every-istand-ophobe6320]

I'm sure there is PLENTY of those cores around. Pentajunk

[@noodles5508]

That’s funny my old Chrysler had one of those in it, went through 4 radiators due to a blown head gasket interesting to see how it would look torn down.

[@Johnc259]

Started with your channel and about 10 people. My how you have grown. Very proud of your channel ideas. i.e. no loud music, no sponsor junk, just tear downs. Also, I admire your business ethics. Don’t sell crap! Hope to see you become a KZbin mega star one day. Be safe. Peace

[@emkaythree]

I'd love to see like a "shop tour" video, during a normal working day, so we can see how the shop works, and what goes on, also the guys that work there. Then transition into a teardown? What do you think? *Fan from England * 😁 Luke

[@KangoV]

Yeah awesome channel. I bet there's quite a few of us from Blighty on here ;)

[@emkaythree]

My Saturday night engine tear-down fix. And it's a HOT one!

[@gtpanoz]

Even when its half-dead, the dipstick is always the most difficult fight in a teardown.

[@crazieman]

The dipstick is clearly Eric's mortal enemy.

[@localroger]

@@crazieman Eric and dipsticks are like Sideshow Bob and rakes.

[@hydrocarbon82]

The LS is easy tho, it breaks off at the o-ring just past the exterior which lets you push the remainder inwards with the right sized drift.

[@toomanyhobbies2011]

Everything I see about the LQ4 makes me glad I've got an LQ4 in my '03 truck.

[@foxman105]

The loose screws on the outside can happen because of the heat. If gasoline burned, it's over 900 celsius fire. At that temperature, alloy looses any heat treatment properties it had. I'm honestly amazed that you got a good looking engine core in the end. I'd be very interested in seeing a shop clean this and build this into a normal engine and see how it fares. Considering it got unevenly heated and then rapidly cooled, there's a good chance it's hiding some interesting internal stresses in that casting. I wonder if with normal operation heat cycles they'll Dissipate or will they end up utimately warping the engine. This is like a science project. I have apsolutely no use for it but I would love to follow the journey of this block, maybe even buy it if I lived in Freedomistan and try to take it for a journey my self. Make a Pontiac Phoenix LS swap to make it appropriate.

[@misterdeedeedee]

thats what i was thinking, especially considering head bolts are torque to yield. when brought to such a high temperature it basically annealed them, relaxing all of that tension and removing the clamping force they had on the head. and also yes, im sure that block is sure to have some stresses and warping at least on the thinner features like the unsupported portions of the cylinder walls and the rods themselves.

[@crazieman]

Nice ponka pfp

[@allangibson2408]

Cooked gaskets can have the same effect. (Basically the gasket material burns away). With high temperatures the bolts can also get longer and lose temper (which is why reusing bolts under these conditions is a particularly bad idea).

[@dobbinj]

I agree with the thought process, but there isn't that much gasoline at the engine. A little in the fuel lines and what not, but the fuel pump didn't keep running fueling the inferno. Once it get going it was probably mainly a big plastics fire. Still nasty, but I dont think plastic burns as hot as gasoline. I would love to see what the future holds for this block. If it really did get that hot it could develop some interesting inspection ports in the near future! LOL

[@chriswilliams2652]

That was my guess too.

[@litz13]

This is a clear example of the difference between "in a fire" and "on fire" ...

[@mysock351C]

We often use the metaphor “cooked” but in this case it literally IS cooked. I hate cleaning up cars after fires. Nothing like sifting thru crispy wiring to see what needs to be replaced.

[@TheMhannah100]

It's crazy how much I look forward to your videos dropping. Thank You!

[@TechGorilla1987]

Bro, your humor is on fire. You're going to get flamed for cutting the wiring. This is a nice soot-uation to be in. I'm going to go blaze and keep watching.

[@arthurcortright2186]

Holy crap! That many wires? I'm gobsmacked!

[@goldenjimbo007]

My wife has a 3.6L Pentastar and I've got a 5.7L Hemi (post 2009 when HP was bumped to 370)... We both watch your videos together every Saturday night and either one would be a HUGE hit!

[@wyattgardner3552]

6am here on the East Coast. The house is asleep and i have my tea in hand watching this goofball have fun for us. This is a good morning. Keep your stick on the ice fellow gearheads.

[@khrisyeet8022]

I say tear down the engine how ever you want to. People get butt hurt over nothing. I like how you drain your engine, and I like your push rod puller technique.

[@Backroad_Junkie]

Yeah, some of the best moments are when he pulls out the hammer, lol...

[@bb3intheoc898]

I've been robbed! I love the sound of the head bolts breaking loose. Totally deprived:-)

[@nathangreer8219]

"There are several degrees of engines being burned..." I see what you did there 😀

[@Sim-633]

You should make a video on how much (ballpark) short blocks, heads or cranks go from junkyard. that would help people avoid being taken advantage of.

[@3gunshooter60]

I have that same engine in my GMC 2005 2500hd, just rebuilt it after 238,000 miles because it bent a rod. Great motor.

Weld vise grips to a slide hammer. Like a Morgan knocker. For those pesky oil dipsticks. 3/4 black iron couplings are cheap you can make all you want!

[@dannythompson1948]

Never gets old watching you tear engines apart, bro.

[@thelazarous]

I drive a 2016 2500 HD with the 6.0, solid engine with plenty of power and at 155k miles plenty of reliability, though it's a work truck that receives religious maintenance.

[@peted5217]

300K [with minor oil leaks] is well within the realm of your good upkeep, Trans can last that long with 100k filter/fluid changes in normal use.

[@drferry]

Throwing away that twisted plastic on the top of the engine reminds me of an old Far Side cartoon: Surgeons are scrubbed in on an operation around a patient when an unidentifiable organ goes shooting up in the air. "Whoa! Watch where that goes! We may need that thing!"

[@therealdojj]

Glad you are wearing gloves, fire damage can leave nasty stuff behind

[@peted5217]

Good point. Gloves advised on any fluids or their offspring.

[@mysock351C]

12:30 Good example of why I like to run pushrod engines at about 4-5k RPM for 15 seconds or so after doing major work requiring new pushrods and/or rockers once they have had some time to break in. Stops the pushrods from just staying in one spot and scuffing real bad like that. They need the high RPM to ensure they actually rotate around like they should, otherwise it tears up the ball and seat.

[@SkulkerMechanic1989]

Hey fun facts for those in the back that don’t know. Those head bolts heat up in a fire and stretch slightly. However if they cool too fast like let’s say a fire truck hits it with the hose. It will cool and stay stretched and seem loose.

[@donw3912]

I have watched a bunch of your prior teardowns...this is the first where the bottom end is staying intact. As you said burn rigs are a gamble but I would say you won on this one quite nicely:-)

[@63bbray]

Another great teardown! On an LS, the rear rods and mains actually get oil first. The oil flows from the pump straight back to the oil filter, then to the lifter galleries and off the lifter galleries to the rods and mains rear to front. Oiling issues will usually show towards the front of the engine first. Love the see a Ford 6.2L or an Isuzu 4HK1 diesel (NPR/NRR/NQR) teardown.

[@johnalees99]

I wonder if it is something to do with the heat of the fire has caused the head bolts to back off a bit. Would have set up some interesting expansion and contraction cycles, depending on how the fire was extinguished.

[@robrayne9144]

I bet this engine was "rebuilt" and it came back to the shop and instead of dealing with it, it "accidentally" set on fire

[@SDSmither]

@@robrayne9144 yea, I could see them doing a compression test, seeing the low numbers and doing as you said. The head bolts not being torqued down enough could easily cause major compression issues.

[@noanyobiseniss7462]

Aluminum expands faster than steel, hence heads stretched the bolts a bit.

[@audiodiwhy2195]

Always like this channel. subtle humor and It’s good to see how seriously you take your work.

[@SammichtheStout]

I really enjoy watching these engine teardowns. It's interesting to see how the engineers have solved or ignored or created issues by design. I went through the teardown history and I don't see a 3rd generation VW EA888 1.8L engine. That's the one I'd really like to see. The 1st gen EA888s were notorious for intake valve buildup and turbo oiling/cooling issues. The 3rd gen has those issues solved and it's got some interesting features like the integral exhaust headers, liquid cooled turbocharger and othersm. Please teardown a 3rd generation 1.8L VW EA888!

[@peted5217]

I believe most of those motors repurposed as 'Boat Anchors' in deference to expensive rebuilds

[@Dan-ez6dr]

Glad you came out good on the burn job. I lost a fresh built 350/350 in a house fire years ago and there was nothing useable. It came to rest on it's nose and everything on the high end was black and blue.

[@nubbyplaysbass]

Congrats on 100k!! Been watching the channel since 15k I believe. Love every video and have learned a lot! Keep up the great work 👊

[@StormsparkPegasus]

Looks like the fire was hot enough to destroy anything plastic/rubber while not being hot enough to damage anything metal. That entire engine is probably rebuildable honestly. Sure all the gaskets and such need to be replaced, and it needs cleaned up.

[@clifbradley]

When my dad was a truck driver, he was in Minnesota in winter. My dad ran his truck all night because being from Florida, he didn't have an engine heater and he knew not to let the engine get cold and freeze. Well the guy next to him didn't listen. But that guy decided to light a trash fire under the engine. He got the engine block good and warmed up alright. He heated the oil pan up so much that the oil pan exploded off the bottom of the engine, caught everything else on fire and torched the front of the cab. It was so cold they couldn't get the water hoses to pump, so they literally got a snow blower and blew snow all over the engine to put the fire out.

[@litz13]

There's video of a Canadian highway crew doing exactly that to douse a house fire while waiting on the fire department to arrive.

[@sendit9129]

Wild guess on the headbolts: Being a TTY bolt, I imagine the expansion of the engine while it was being roasted Yielded the bolts more- and being a TTY bolt.. they never contracted like the rest of the engine did.

[@derekbennett5896]

Been a gm tech for over 13 years now, I've seen the ends of the pushrods look like that for no rhyme or reason, some with high mileage, some with low mileage. On perfect running engines with great oil pressure.

[@LSmiata]

Hello I Do cars, Definitely hot on the top, but doubt oil temp in the pan got to normal service temp.

[@4wdiesels]

These GM small blocks are delightfully simple and terrific runners. I had an '04 6.0 that was a gas guzzler but did everything I needed. Absolutely terrific design.

[@PuddinJr1993]

Not sure how I ever ended up here but I'm an appliance repair guy. What you need is one of the catch pans that you put under a washer if they leak. I think your whole engine kart would fit inside it amd would catch all the nastyness that runs out.

[@Yankee7000]

Should I give up on the VQ35DE…. If so, never mind. I shall continue to enjoy your presentations. Never a dull moment.

[@45AMT]

We've bought a few burned engines and had pretty good luck using them in stuff that needed an engine. I always re torque the head bolts and check the bottom end. BTW that Tahoe PPV is pretty sweet!

[@allenbeaulieu7077]

Fine job buddy. All the plastic crust stuff popped right off. That engine looks pretty solid. Big Al.

[@SB-vb8ch]

The dry rocker suggests a faulty lifter as oil feeds up through the pushrod (or not in that case). Surprised you didn't look a bit more closely at the lifter on that lobe/pushrod/rocker.

[@sergeymatpoc]

excessive heat changes material structure, so I think that's fine that bolts were loose. They just overheated, extended, and left in that condition. Potentially there could be any random issues with the engine, but I don't want to predict anything, I hope it'll work at least a million mile more. Decent, reliable engine.

[@metalted6128]

I learned years ago, a motor that needs a rebuilt, that is very oily, and grungy! Hasn’t been overheated! I tested that theory a dozen times, in rebuilds, It’s true. Heat cooks oil off.

[@keeperofthegood]

With such inconsistent torques on those head bolts, have to wonder if the owner just had the engine serviced and the tech that put it back together was sloppy in more than just spec's.

[@VikingDudee]

Heat can do that though, I've had a 5.4 with 25,000 miles on it that was on fire and the headbolts were all different torque, some almost even finger tight, Pretty sure the heat of the fire just warped the aluminum head or even stretched the head bolts some.

[@steveb6103]

You saw the melted plastic? No way did anyone work on the top end.

[@randr10]

I think that's possible. Also, head bolts come out a lot easier if they were torqued down recently as opposed to after a couple hundred thousand miles of heat cycles..

[@hynestimothy411]

Glad you're making more videos

[@dj153212]

My volvos 3.2 has been on fire, replaced the wiring harness and cleaned off the fire extinguisher chemicals and she's still running strong

[@YoDooDSup]

How come the top end looked so clean and seemed like the oil was changed frequently but then the oil pan had sludge? Am I missing something here?

[@burritothenoodledragon]

the heat from the fire may have cause the bolts to expand and when it cold it down it shrunk think of how you use a torch to help remove a stuck bolt with out snapping it

[@r.glenncooper8199]

That's gotta be a lot of fun....Just taking engine's apart, an looking for carnage....Keep the videos coming!

[@fmerkl]

that little rust stain will never hurt any thing ! I bought a used motor for my '01 Ford F150 ,That had sat outside for 6 years without exhaust manifolds on it for $300) pulled the heads and there was a slight rust stain on 4 cylinders that the exhaust valves were open , Put new head gaskets in and head bolts as there toque to yield, 100 K its still running strong ,) for oil consumption 1/2 Qt in 3000 miles !!

[@TPL2018]

Congrats on 100k, been here since the first 5.0 coyote you did I think. Keep up the awesome work

[@I_Do_Cars]

Thanks! Hard to believe.

[@Flies2FLL]

Perhaps I am wrong, but I would think that an engine that had been burned still had a core that was in most cases useable. I haven't watched the video yet, that is why I say that. Buildings in Flori-Duh, which are all concrete block, typically resist fire very well, but they are always knocked down because the heat deteriorates the strength of those blocks, and you could wind up with a collapse down the road. This is true of any concrete structure. Aluminum or iron engine blocks probably don't have this issue. Try this: Put on GOOD eye protection and a leather jacket, and then use a MAP gas torch to heat a paver or your concrete driveway; You need to have the eye protection on because the concrete chips will fly at you....

[@gainerman]

I brought back a 540 bowtie motor that got so hot the Holley dominator melted ,dripped through the supercharger rotors and a few slags ended up in the heads. Ended up with better head to block deck seal then my decked 502 stroker. Guess you could call it "heat treating" . Its nasty ,but don't be scared of the burnt ones lol

[@markjmaxwell9819]

This engine has an Iron block with alloy heads as does the LQ9 both are good engines to start a performance build with. But If I was going to do a stroker such as a 408 build, my L77 would be a good place to start as I prefer all alloy engines. 😎🇦🇺👍

[@Don1Gibson]

Still waiting for the 'one time and band clamp' comment.... :D Cheers for another great video.

[@austincjett]

Glad you came out good! What really surprises me is the head gasket hadn't blown with the bolts that loose. I suspect the heads had been off before and the "mekanec" didn't own a torque wrench. He might have messed up a fuel line, that could explain the entire truck over heating. Here's a question, how often have you seen a LS with a blown head gasket?

[@jamesparks2242]

Comment on burned engines. In the late 60's my dad and I were at a junkyard looking for something. They were pulling the heads off a burned 63,64 Caddie. Heads were in high demand. Every 390 I ever pulled the heads on had at least one cracked head. Well, they got them off and the center 2 pistons in each bank were melted. Looked like a piece of plastic someone had thrown in a fire. Years ago the local state trooper had a motor home he could not sell. One weekend he moved it down to the roadside fence in his pasture (well away from his house) , blocked the gate with his patrol car, and went to a restaurant in the next county. Well, somehow that evening it caught fire, FD couldn't get to it because of the blocked gate. Hmmm. It had burned down to the ground, nothinng but the rails and the drivetrain left, melted the wheels of it. The carb and distributor were melted. My hot rod bud that recovered it bought the engine from his boss for $400. Told him he was crazy. Said the code speced it as a forged crank 4 bolt big truck engine and the crank was worth that. He replaced the externals, put it in his mud truck and drove it for a year before putting a hot rod build in it to go in his 86 K10 show truck. He always told me it was such a good engine because it had a heat treated block.

[@christophercasale7961]

Would it be worthwhile to have a bench setup for 24 tooth gen 3s? Where you could just slam an intake on it to see if it runs?

Back in the 80's when I was in the firebrigade, on the vacant land not far from the station there was row after row of burnt out cars. It was like a shopping center carpark. Then the insurance companies stopped paying out on cars that were (stolen) and burnt and it stopped at once. By the way, burning cars don't explode in real life, only in the movies. The fuel mixture in the tank is 100% fuel and fuel vapor and 0% air.

[@bradhaines3142]

one time i got a transmission from a junk yard, i made the mistake of asking if he knew if it was ok or not. his response was 'it was running until point of impact' so i imagine this engine was 'running until it externally overheated'

[@osmo_9577]

Those stuck valve lifters and loose head bolts might indicate that there is minor heat deformations. Cast iron is quite sensitive for that. Also if you put it out with water, it may give block some cracks when hot cast metal cools suddendly and unevenly. I am very afraid always when i see burnt cast iron, but theoretically it might be good if someone puts that to tuned car and tries to get horsepower. Block has no tensions and it doesn't fail from liners. But what i'd do is good visual crack checking, maybe new sleeves and put everything together.

[@peted5217]

I've seen that pushrod/rocker wear on several LS type 150K + motors. Not so much an oil pressure issue, more like lube age breakdown, likely infrequent maintaince . In any case toss the old and new replace with lotsa asm lube,

[@fixxerautomotive4917]

I always wanted to see what a lightly burned engine would be like inside. I see them in the junk yard now and then but always passed them by. Maybe ill look a little harder next time... I think that bit of plastic may have been the tab on that oil filler tube; you know the 45 degree elbow? They aren't really meant to come off after seated and if you reef on it to get it out, a little plastic tab breaks off inside. Probably been in there a long time I bet. I would also wager that that engine is a good running engine, I think all it would have needed was a set of head gaskets and bolts due to the heat- metal expanded too much over crushing the gasket and stretching the bolts i would guess. You should make up a engine test stand so you can try firing them up in the shop (make up an exhaust with a big muffler so you can really hear everything), then you could make a video of a running engine to help with the sale and your own conscious. Something that i want to do as well, then I could buy engines out of the junk yard and know what the issues are before installing them in something. Great video! Looking forward to the next one!

[@Backroad_Junkie]

Can you do like a 60's V8 that has no electonics or anti-pollution stuff on it? (Maybe even a straight 6...) It'd be interesting to see what an old school engine looks like vs. a modern, electronically controlled one...

[@robertf6344]

For one thing you can count the # of wires on it on your fingers.

[@peted5217]

This burnt 6.0 LS is nearly , exactly what you see inside any domestic [Non-ECM] Pushrod V8 since 1950s. Metals are better now and much more accurate machining also. Cylinder head design is main reason power outputs continue to improve. That's why an LS motor will make the same power fueled by old skool carbs in place of it's ECM-EFI
