6L LS burnt in a fire! Can we get it to run ? 

Ok just so everyone knows things I've tried or looked at are starter is not stuck but did try another starter still the same deal don't see anything wrong with the flexplate, checked the sensors nothing touching. Bearings look good, timing chain isn't rubbing anything, the rector wheel doesn't look like it's rubbing anything. Starting to think maybe something with the cam or lifters but really can't see why haha.

Dr Brent is in the burn ward saving a critical burn victim ! Way to go! great video !

Hey Brent, as a retired funeral director I'd say you did one bang up job of resurrecting a cremated 6L LS. Great work and a very gratifying video. Claim success whenever you can. Take care my friend. Thanks and we'll see you next time.

I'd look very carefully behind the flywheel because that's the only spot that you can't take off and look because the way it's mounted on the stand so maybe there's something flopping down in between the flywheel and the block

The noise can simply be from the fact your engine is on a stand, not on rubber mount as it is in a car ( maybe 😉) In any case you have done a good job with this engine revival

Always amazing how Pablo just hangs out with all the action going on around him. Outstanding Poochie

Thank you for continuing to make these videos by the way. Your positivity is one of those indelible things that I think wears off on all of us. You definitely been through a rough patch and it's awesome to see the way you deal with it.

Nothing phases you. Just keep pushing through. Two sensors on throttle body, throttle position sensor and idle air control. Sounds like starter dragging on flywheel. Common failure. Something with starter drive returning. Windage tray.

The man never gives up! 💯

Ehh, it'll reveal itself, just really glad to see you digging in on a late night session where what the shop is almost does'nt matter. Hope you enjoyed a wobble pop to close it out, cheers

This is looking at disaster in the face and saying I am moving on, you aren't going to stop me. Awesome! Watching this had me all over the place with my emotions of my own struggles. Keep on keeping on my friend.

Can not believe how good an attitude you have Brent, I would be so upset that it has a little problem after doing so much to the engine for what you started with. Call it a Win

Congrats Brent, on getting ur 6L ls motor rebuilt and kind-of running for now. sounds like u didn't feed the Squirrels! lv to Cool Pablo..

Probably valve train lash from a bad roller lifter. Only you and Pablo can do a will it run on the engine stand! That was awesome. Keep up the good work 👍

Brent I have no experience with the 6 lt but since you can hear that noise at about midway back in the engine and loudest near the oil pan rail I believe it originates in the crankshaft or cam area. Since you have already removed the pan and windage tray and found no wear marks or on the dipstick or tube either, I suggest this. Remove the valve covers and use the starter to rotate the engine while watching all the rockers movements. All moving up and down fairly equally? Loose or bent pushrods? Bad lifters or cam? Compression test it? Also, possibly a sloppy timing chain set. Maybe remove the intake and valley cover to inspect the lifters and cam. Cam position sensor rubbing on the reluctor? Remove the bolt and lift the sensor an 1/8 inch or so. Or you may just elect to shove it in a corner somewhere and deal with this if or when you decide to stick it into something.

Watching a tent wiggle the harness and look at it perplexed reminded me of Clark W Griswold when his house wouldn’t light up

That motor looks to be in good shape for the shape it's in.😮

6.0 truck motors have cast iron heads. My 2009 Silverado 2500HD has iron heads. 14 years of trouble free reliability. She'll be fine, just needs new accessories and a cleanup. Thanks Brent! Cheers from Utah.

As crunchy as that thing was, its amazing to hear it breath life again. You are definately the ls whisperer.

You sir are the poster=man for "Winners never quit " and I salute you .👋👋👋👍

You are a patient man Brett.

Pablo speaks a Brett listens!!!!

That fork lift is ideal for your work.That long reach is great.

If I'm not mistaken Lq4's are externally balanced and Lm7 are internal. That wouldn't make noise but cause your vibration.

Fascinating. You've added to my knowledge and proven once again you are a mechanical wizard.

Brent you my man are persistent and patient "bearing pains or trials calmly or without complaint!" keep up the great videos!

Is the ringer on the starter motor touching on the flex plate when it’s going on mate??? Cheers, have a great day 🍻👍

There is a reason it is making that rubbing noise. Timing chains, flywheels, tensioners and what ever else that is connected to the crankshaft….what ever it is, the engine ran pretty good for it being in a fire. I agree with you….. it is a win.. you will probably find the cause by accident….

You'll figure it out Brent because that what you do. On a side note, during the engine cleaning there was no music during that part so I played "Burlesque Heartache by RKVC" that I had downloaded. There, much better.😁❤

Well it's cleaner and it runs win win sort of .Well done sir Brent thank you for sharing

Thats exciting when you do a start up on an unknown engine! Great job!

Morning Brent.......at least it runs, you will get it figured out..

Huge undertakiing- very ambitious! Loved the burnout in the last episode too bro!!!

Love hangin' with you Brent... Goood to c the supervisor hangin' with ya too. 🐶 Amazing what you did with that engine...👍 awesome knowledge brother 🤠 Amazing grace...🙏 YES , IT'S STILL A WIN

Man these things are tough !! ...almost as tough as you, my man. Big HELL YEAH from a fellow canuck somewhere in Quebec.

Glad to see you working hard again. It’s been a long road. Cant wait to see more updates an projects and many more videos soon Brett. Keep up the great craftsmanship and hard work my friend. Fab On. Weld On. Keep Making. God bless.

He picks up an engine that's burnt to a crisp and says "I don't see why it shouldn't run". Priceless.

well Brent, that sure was a great project, love when you revive things that no one would ever attempt , cheers! 👍🍺🍺🍺🍺

Good job Brent.

Great job buddy, I’m glad that you at least had one to be able to save. It’s sad too loose so many toys, but I totally have faith in you. Your friend always. Kevin

Good job Brent. You will figure it out.

Do these engines run timing chains? Maybe the tensioner pads are melted and the chain is slapping .

It was fun to watch ya and see this LS coming back to life after all it went through with that fire. Hope that you'll find the source of the noise. Later !

Hello Brent, you are amazing. I just got through cleaning the three major black and white engine grounds, and both knock sensors on my sister's 2007 5.3 chevy. I should have waited for this video. Your knowledge and watching you is educational, teaches us not to give up, and troubleshoot our way through. Another excellent video, thank you again and I will be waiting for the next class Master Tech.

i'd check the oil pump. The centering of them is delicate and with heat it could have developed a rub

Did not think that 6.0 would live again.Good work Brent

Sounds like the reluctor wheel rubbing on something. Possibly the crank position sensor partially melted and out of position?

I know you won't quit, looking forward to the next video to see what the issue was.

An amazing video Brent! Way more sketch than most videos? Loved it!

Nice work, I think the grease/dirt on the engine insulated it from the heat 🤣 I'm glad she lives again!

To me, that is a win! from what it was to it running, that's a big win, you'll find what the problem, keep on keeping on 👍

Your freaking amazing... who would of thought... and it doesn't even smoke!

Hello, Great videos. The first time cranking it sounded like the flexplate was hitting something on the back of the block or a bolt on the engine stand. Best wishes. With the shake at idle, I'd do a compression test.

Good Job, you are brave!

Hope the Motor is good and love your videos

Try the ol hose trick to the ear and move around the engine to center in where the noise is, how about a electrical spark, it’s a very constant sound, turn the lights out , might see a steady flash….my first thought was timing chain

I’m 76 years old and watched you build the General It inspired me for one more build. I’m doing a 1947 Dodge pickup on a Chevy 4x4 frame and running gear . So I call it a Dodgrolet. I’ll send pictures when I figure how to. Sorry to see what happened to your shop. Can’t wait to see you in the new shop.

Minty ! Thank You for sharing your video, and letting us hang out . Later ...

Thanks for another , Brother !!

Put it in your car and turn the radio up full it will be fine my friend.luv your attitude and work mate god bless

At least the old motor runs maybe not race worthy but runs. You never give up that's one of your good characters. Absolutely love all the videos you make never a dull moment 👍👍.

When you absolutely need to know if you have a running engine... lol Remarkable setup you got there Brent. We will not try that at home. laughing. LOVE IT

This was a wild one- what a marathon- but ya- considering what you started with- definitely a win. Can’t be anything too serious

You are putting heads from a smaller engine onto a larger engine. The chamber size must be smaller on the aluminium heads to maintain the same compression ratio between the two engines. It is therefore possible that the valves are touching without bending. Also it appears to be running rougher than I would expect. Check compression and check pistons with your borescope. :)

The pink wires are 5v reference power for the sensors, not meant to have 12v run thru them .

Great video Brent, I'm very impressed that you got that engine running again. You sure make all that wiring look easy, i'm sure you will figure out just what that little noise is. It doesn't sound too serious to me. Good luck with it..

I'm not sure either, but I hope it is a simple fix and hopefully you can find, it sounds great and I'll catch ya on the next one

Sounds like a win

Great work Brent..

Thanks Brent.

I am surprised that after all of this time you have not made yourself a universal engine run stand?

Like another feller said, you don’t usually have your ear right next to the oil pan. Probably a normal noise. Regardless, that was entertaining!

Awesome job 🎉win win I like it that you never give up keep up the awesome videos😊😊

Love those test parts

Great job. Another good one 👍👍

Only Brent can take a basket case like that engine and make it run. Hopefully the new shop is coming along nicely

Wow ! Sir you're the only person on RU-vid I've ever seen do this. When you trimmed that wiring harness,all I could do was shake my head. There's no way I would've even thought about doing what all you done. They should call you the Modern Day Mc Gyver. Best at what you hands down. My hats off to ya Sir. Many Blessings to you and the family ❤😊

Nice job Brent, and yes I saw the T-bird on the stands, hope what's ever in it 390 maybe can be saved, love FE big blocks, another great video :)

Brent you’re like the Mad Scientist building Frankenstein. It’s an awesome watch!!!

Sounds like the lifters took a dump on it from the heat

I had an old harmonic balancer that had spun on the rubber, made a heck of a noise. Maybe the fire melted the dampener rubber?? It does sound like one of those old “rattler” balancers. Anyway, I’m very confident Pablo will lead you to it soon. 😂

Time to make yourself a run stand. Thank you for taking us along

Great video metal master, enjoyed watching with a cold beer big ups 😎

On the video, it sounds like lifters. However, I have heard cracked flywheels sound the same way. About drove me crazy trying to find that. Outside of that, it 's a win in my book too. Considering what it went through and how it looked, running at all is just plain amazing. Good job!

Brent, you add a new dimension to the typical "Will it run" videos. Your videos explaining fuel injection, ECUs and wiring connections will be valued by the next generation of car restorers.

Great achievement to get it to go at all. You’ll solve it!!!! Well done

You need to check the crank by rotating it with out the pan on. Maybe something is different in the 2 pans...

You amaze me every time. Your. Willing. Tu try. The. Impossible. Feat. To me. I need everything. Tobe. There. Thanks

Just a thought but as a last resort you could try pulling the dipstick out a little ways to see of that is it. You did mention the potential.

Love it

Awesome that it's running again.

Use oven cleaner to clean the grunge off that engine. Better than any degreaser I’ve tried.

Rainey day's and Monday's always get me down 😊

I give you credit. You don’t give up on much at all.

Time to use your mechanics stethoscope to narrow down where the noise is concentrated…had similar noise years ago ended up being one of the bolts on the flex plate rubbing.

Thanks for another great video!🐾🍺

Given the Balancer was cooked, could the timing chains/guides have been affected by the fire, or a bit of crap floating around? My first idea was the Windage tray, but that seems to not have any rub marks.... Self clearance is my only other solution 🤣. Cheers from Australia😃👍

Sound like the lifters needs to pump up. Make sure you have the right wires going to coils and injectors, you might have one crossed.

From the char grilled mess you started with, it feels like a win to me too. hehehe

Have you looked in the lifter valley? Top end/lots of moving parts to check out.
