Rebuilding a 5.3 LS!! - (Part 1) 

There is something inherently satisfying to the primal senses about watching an LS get disassembled

Nice to see 2 brothers working in such harmony, and so efficiently. Nice work!

"That oil looks super clean, just a little dirty".🤣🤣🤣

I'm the rookie of the bunch. I love watching experienced engine builders for I learn a lot. Very detailed info on socket size shows you've been there along of times. Thanks for the class. Looking forward to assembly. Keep up the great work. Trucker Ray ✝️

"For both of you that watched my previous videos..."😂😂😂 If i ever go to Nebraksa I have to buy you lunch somewhere! Same sense of humor! I enjoy you attitude in the midst of the chaos! Thank you!

right now im at a big crossroads on how I want to build my impala. Its a 61 with an original 283 in it. But when you guys were talking about the 6 bolt main, it's making me wanna LS swap it. Its like future proofing myself cause initially i don't want a whole lot of power out of my car, but in the future I might wanna push it a little more. LS would allow me to do that with no worries at all. Enjoying the content!

You Boys keep the engine stand companies in business !

Congratulations on your work great information and I appreciated it”

Got the 5.3 silverado can’t wait to see and learn more

It’s amazing how simple these engines are compared to Fords…

Yall just gained a new loyal sub

I’ve got a buddy who’s REAL big into rotaries, 2nd gen RX-7’s and drifting. I’ve also converted him into an LS lover just by talking about them and telling him how modular and adaptable they are and what about them inherently makes them so strong and good. I don’t even own an LS! I had one at one point but no more.

Interesting, cool video. Impressive and inspires me to learn more!

Great work brothers! Nice video

i couldn't watch when you were leaning on that engine stand. glad no limbs or lives were lost! please be careful with that. liked, sub'd & on to part 2

I'm gonna pretend I didn't just see you using a torque wrench as a breaker bar.....

thank you for doing this - awesome video!

after trying to loosen the crank bolt with a ratchet, I watched an old boy take out a crank bolt with his fingers.... after tapping it on the end with a hammer for a while. It was amazing to watch an old school mechanic with some practical experience and a few tricks up his sleeve.

I'm guessing this isn't your first rodeo. Sweet video just what I was looking for.

lmfao I love that moment at 10:10.... when it started clicking into place why so many people talk about LS swapping and call them legendary powerhouses. "They have six bolt mains?!" lmfao I was smiling so hard during that moment since it reminded me of the same thing I went through.... you see all the qualities that go into a racing engine and then look at the LS and it's selection of GM parts from all the various models and you just start getting uncontrollably giddy.

Lots of CoolToys in the shop!Love it!

Awesome video guys! Thanks

I love this channel man

awesome job❤

Also I am very new to you’re channel and I enjoyed this🤟🏾

The last motor I stripped down was a 283 Chev. Wow they have come a long way. The first 265's had Rope main seals. Yup come a long way.

Nice well light shop.

Great Channel! Newly Subscribed! Oh and by the way my 07 Tahoe had the same dumb DoD or Afm addition.

Nice shop guys

AFM (DOD) was actually started on the general line vehicles in 2007 but they were used as early as 2006 on escalades and other high end vehicles.

if you need a worker, id love a job. I started off working on 5.7 Hemis and I know everything about them. Started learning LS engines since I have one. I started learning transmissions. I actually enjoy working on Engines and Transmissions, so if you need an Employee that LOVES showing up to work, im your guy.

Man I wish you guys had a shop close by in NC! It seems the dealership missed so much with my 2008 1500 Silverado with a 5.3l engine with 181,500+ miles. They tell me the rough idle, excessive exhaust vapor, gas smell, and dimming lights is normal and can't find anything wrong, but I know it's not. They missed a burnt up head light harness, buzzing cabin ambient temperature sensor, and wobbly harmonic balancer. I fixed most of the issues, (broken transmission and engine oil tubs, ignition coils, spark plugs, wires, door harness and actuator, a ground fault, evap canister, purge valve, charcoal canister, all vacuum hoses, intake manifold gaskets, injectors, MAP and IACT sensors, blower motor fan, alternator, blown fuses, broken door handle and cable, faulty window and lock switches) but that idle eludes me and seems that it kills batteries without a parasitic draw. I can't get a check engine light to come one, only a "tighten fuel cap" light. I do hear a "bubbling" and "gurgling noise on the driver's side while on park and the idle is really bad will at stop lights. I wouldn't mind paying the money to have someone like y'all to look at it!

That motor wasn't smoking that's totally normal to have carbon on the top of pistons with almost 200,000 miles. That engines in great shape internally

haha, crank bolts are a pain without an impact. I broke a few sockets and a rachet trying to get the one off my Toyota 3.0. I ended up building a tool to bolt to the PS pulley holes on the crank pulley and used that keep the crank from turning while I loosened the bolt. Bought an impact socket too, even though I was taking it off with a rachet.

About time you put an impact on it

I wish I live close to you I’ll be applying for a job to work with you I would love to learn about LS s you rock brother I just subscribed to your channel 🤙

A trick to take off the hormonic balancer bolt if you don't have an impact, is to use a big pipe wrench and attach it to the pully on the hormonic balancer ( if you're reusing the part, put a rag on it b/c the pipe wrench teeth will dig into the pulley groves). Then turn the pipe wrench in the opposite direction of the breaker bar.

Please young man, never pry upwards, a,ways downward! I’d show you my scare from having to have my bicep re-attached if I could

Nice work Gentlemen. Gotta love the LS. Enjoyed the video. Sub'd

Best 🔧 is a hardened steel wrench for breaking shaft bolts.

Love the content,what is that a port/block washer ring called and is that the process before boring it out over

Cool vid! I believe DOD or AFM started in 2007

the fact I'm watching these videos to see how one is taken apart and such, because i HAVE to work on one of these things, I hate them. truly a engine i'd throw away personally. after torching a hole in the side of the block.

At 175k miles unless it has low oil pressure or a mechanical issue the LS doesn't require a rebuild. My dad had 410k miles on his engine and it burned a little oil. Besides oil consumption it was pretty clean and needed only head rebuilding, rings, bearings and an oil pump. Thing still runs today.

Good job 👍 June New Orleans

Bwahahaha! Watching the gong show taking the balancer off was worth the wait. Lmao

How does one get a job like this . Those bearings did look great 👍

11:00 in always push down when breaking bolts loose unless you enjoy pain. I could be wrong but I don't think so.

I had mine since 2007. And I took it back to the dealer and told me that it dose that.

When trying to loose that harmonic balancer, I would usually push down instead of prying up put your whole weight down on it

About to rebuild my 5.3 out of my 2000 silverado. 332,000 miles on her. Still runs, but definitely needing a refresh.

Where are you guys located? You guys are great.

You could heat up the crank bolt too before breaking it loose

subbed b/c of this video

Hello. Thanks for the videos. I wanted to ask can a LS engine have good oil pressure with a new oil pump and also have a rod knock?

i have the same exact electric 1/2in impact and everyone tells me it’s shit, but i work at a dealer and it works like a champ

Fixing to pull and do my first rebuild

I have a 5.3 block as well and was wondering how much you charge to clean it and everything?

We're can I find you guys I have an engine I want to get done or I can buy a assemble short block from you guys awesome work 💪

milwaukee impact and be done with it that ballancer bolt comes right off

Your engine is in much better shape than the pulled one we bought 😐

For future a propane tourch heat bolt a min whips right out on them dampner bolts

Id like to do an overhaul on my 2003 tahoe. It runs good thou. Just be nice to restore

I'm with your Brother on the down pressure being better. My 2 cents anyways, Good Video.

Nice shop I’d love to work in there

When burning 1qt of oil every 1000 miles is acceptable. Gotta love GM's PCV system!

Thinking about getting a junkyard lh6 for my truck to try and rebuild with the help of neighbor lol

Looks like almost the exact same engine that’s in my 2010 Silverado, mine is a flex fuel DOD 5.3 aluminum block with 799 heads

Use the best of everything

DOD , AFM converted back to Normal, I thought they had that hump in the valve covers ,over the cylinders that got shut off..ive not done this one yet , the DOD one , the first gen ls done lots of them , this will be interesting to see the differences

Curious to if you know how often the customer changes there oil or whatever they did for matinance to be that clean at that milage thanks

go aggies ! support from class of 2014

When you said your doing a small cam shaft do you mean smaller that stock or slightly larger than stock. If you mean smaller than stock what would be the point of that? Which cam shaft and what size valve springs did you use?

How do i learn to rebuild or build an ls engine? Nice video btw

I heat up the crank bolt with my rosebud then hit it with pb blaster then my 1/2 impact will buzz it right off

U CAN MESS UP your tourque wrench if u use it for just normal loosening bolts use a breaker bar instead

I need to watch this video and am wondering if you could help me because I have the second last lifter that has approx three quarter inch loose in it and haven't tried to see if that changes or if it grinds when trying to turn it over; would it always be the cam's runner for that that would be snapped off or could it be the self adgusing part that is collapsed? t

Is there enough meat in the Aluminum 5.3L blocks be taken out to LS1 overbore sized (3.903/5) like the Iron blocks ?

That was great!! so........ what did the heads look like? were they fouled as well?

nice

I’m guessing that your dad was a military guy... just by how you guys do stuff. Great video. Enjoyed it.

You said you be rebalanced the crankshaft, how you choose pistons and ring before doing it?

Good deal

How to I get a full rebuild kit ready To install ? Tryna rebuild my 5.3 but a lil better than stock

Use a heating touch

Great build. My two favorite parts. 1. Your brother saying "they have 6 bolts mains?" 2. You throwing all the LS parts away your not reusing. You guys are a great team. I think you have converted your brother to LS's. I have a LQ9 that has 170 k miles that I will be rebuilding at our local machine shop. Might do a 408 stroker but not sure.

And them perfect bearings are why u leave it alone!

The cracked rod design was brought out by ford in the 1990 mod engines .

How do you degree a cam for 5.3 Chevy avalanche with 195 in /197 /482/487lift

What brand cam baring tool are using

alot of trust in that rachet instead of a breaker bar

What type of machine is that @17:06 that's cleans the engine.?

If I were to take my 5.3 to a shop and have this same thing done to it what would the cost be? It has 180,000 miles and I would like to have a mild cam installed and the AFM deleted

what vehicle did this come out of? model and year please

What's the site y'all guys sell the engines?

We’re did you get the rebuild kit?

I wanna 5.3 v8 my 01 jimmy the valve bent and basically detonated itself. My question is this is the exact motor I need to find a 2012? Era

It’s posible to rebuild a LS 5.3 just following your videos?

How much for a LS3 or LS4 ? For a 75 Chevy caprice convertible, thanks in advance

Breaker bar with a pip bam solve ur problem that how a take them hard to come off bolts easy.😎
