How to Build a 5.3L LS LM7 V8 - Part 1: First Disassembly
Вставка
- Опубліковано 17 лип 2020
- Today is a really exciting as we embark on a new project! We are starting on a new engine building project and we will have some parts supplied by Summit Racing. This 5.3L V8 came out of a 2001 Chevrolet Silverado with 260,000 miles on it. It made 285 hp (213 kW) and 325 lb⋅ft (441 N⋅m) from factory and we should be able to get those numbers into the 400's by the end of the build.
I am making this video series to show you exactly how to build one of these engines for yourself. Everything I'm doing is something you can do at home in your spare time. Building one of these yourself is incredibly rewarding and something amazing you can use for years to come.
This is going to be a total rebuild with a machined bored block and rebuilt heads. It will be a heck of a journey and I hope you join me on it. If you have any questions please feel free to leave them below. Thank you so much for watching!

You explained all these videos so well!!! You got a newbie like myself confident enough to try it🤣🤣🤣🤣🤣
You can do it!

Same here bro I've never worked on a car by myself but I feel like somehow I could watch it many times and use it as directions
Me too bro
Brother do it!! Only our own minds keep us from doing greatness!!
Dude! I'm rewatching this build series for about the third or forth time. I just love watching this and can't wait to get started on my own 5.3 build. I know I'll rewatch this when I start the build.
NICE! So good to hear! Send me a picture when you are done! Thanks for watching!
Hands down the best detailed tutorial channel on UA-cam. Keep up the quality work man, us viewers greatly appreciate it!
Thanks for watching!
Just wanted to say, the Knock sensors are for measuring preignition/detonation, which can be catastrophic to the engine if left unchecked. The computer can retard timing and adjust other things in order to combat it. Detonation causes increased cylinder pressure and temperature and can result in melting a piston, for example.
16:50, those steam vent lines are also to used to help bleed the coolant and prevent hot spots. The knock sensors are also there to prevent detonation. Great video btw
The best series I've found for LS building on youtube so far!
I'm building a 1961 Impala, and decided to keep the OG 283 in it, but I want to build an LS for it later and this video is giving me confidence to do it and making me ansy to finish my 283 as well lol! Thanks for the great content.
I was building a 454 and following along with your series but have recently got a great deal on an LS and have decided to now build it. What a great coincidence that you are doing a series on an LS now😂 i already know this is going to be a great quality and detailed series. Definitely will be keeping up on this one.
Oh man that's too funny! We are still working on the 454 as well. But we really wanted to start this LS. Thank you so much for following along and watching!
This is the best engine disassembly tutorial I have found. It is outstanding how you go step-by-step process.
Thank you so much for watching!
this is one of the few channels who actually walk you through it while explaining it. u real for dat 💯🙏
Awesome! Thanks for watching and subbing!
As someone learning this was a pleasure to watch
I’ve tinkered with some junk these past couple years but have yet to refurbish an engine or make a swap so I’m hoping to get a refresher course from your series, much appreciated!!! One down, 12 more videos to go!
Absolute love the LM7, Built like a masochist and loves to go
Such a great engine! Thanks for watching!
Currently in the process of not really “rebuilding”, but more as, changing stock parts that are broke to ensure it will run.. hopefully 😅 but, I have been rewatching these videos as references to where hoses go, torque specs and probable causes. Very helpful for me personally and I am so glad I managed to find the exact engine you’re working on. 😂
Wow! Teaching is its own skill and you are a master. Thank you for remembering wring what it is to be brand new.
Thank you very much!
Awesome! im also a newbie and its great you show the dismantling since most of the youtube LS rebuild videos seem to skip the removal of the accessories.Luv the videos and keep them coming :-)
Thanks for watching!
Im brand new to the Ls. I have learned many new things. Thanks for the video.
Thanks for watching!
Wow really nice delivery on the steps and super clear concise, well explained. I'm a fan of that effort. Well done.
Glad you enjoyed it!
Been looking for videos like this for a long time... you explained so well,!
Glad you liked it!! Thanks for watching!
Good stuff!!!! Retiring my 327 in my 53 GMC and sliding a 5.3 from a 2003 Silverado into it. I'll be doing a complete go over on it with a couple of upgrades. Your video's sure save some time on specs etc, thank you for that!!!! Keep up the good work, cheers!!!
Sounds awesome! Thanks for watching!
Wassup. I watched this entire video and it was so easy! And well explained. i explained it to my wife and she actually understood. Not trying to be funny but a man explaining a v8 to his lady is not an easy task and you sir made it very easy. SUBSCRIBED!
Very cool! Thanks for watching!
great video.. exactly what i was looking for.. thank you
great rebuild cant wait to rebuild mine ,
Nice video, well explained. Really made me feel like I can do it. Thank you.
You can! You really can! Thanks for watching!
@@2carpros where are you located
Built enough of confidence to build my first bbc because of this channel, now I’m going to give this a try!!
You got this! Please let me know how it goes and if you have any questions you can ask me on Instagram ryansgarage408 or post a question on my website www.2carpros.com
Thanks for watching!
@@2carpros will do, thanks!
Thanks bro you made that very easy and safe
No problem 👍
Awesome man!! Thanks for this series! 💪🏾💪🏾
My pleasure!!
Great video! Thanks
Thanks for watching Jeff!
I was so surprised, how well and easy, all those bolts came loose without breaking.
I know, right?
Great video
Thanks for watching Joseph!
Honestly one of the best videos I've watched my dude. Awesome job. I have zero experience with vehicles, just ordered a 5.3l because I wanted to try this out, kind of a dream. And then I find your video! Talk about luck hahaa!
Awesome! Thank you! Best of luck with your build! Let me know how it goes!
How’d it go?
Well?
Wow, I guess you gotta jump out the window at some point.
Smart thanks for the video
No problem 👍
Outstanding Videos!!!
Thank you and thanks for watching!
Summit Racing rocks. They are a sponsor of our boy Cleetus too. They're helping me with my 5.3 NA build. Unless you have never removed an engine before go right to 9:00
Summit is the best!
My L59 is currently at 269k miles. I bought the Yukon when my teenage daughter was born. I can't complain.
Such a good engine and truck!
@@2carpros I have 2 daughters that think money goes on trees. They asked why don't I get a new one. I said I will give you 78,000 reasons why.
You guys are amazing! I just wish I knew how you remember where all those bolts and connections go when you reassemble the motor🤔
If you watch the entire series I show you exactly what bolt goes where. Thanks for watching!
Just picked one up as well 🙏🏼
Great! Let me know how it goes!
Double thumbs up for this video, its always nice to hear explanations regarding design and function. I own this engine, haven't ever seen her undressed, ha ha.
Thank you very much!
Thanks so much for posting these man, my dad’s 5.3 gave out at 387k about 2 weeks ago and he gave me the engine to do whatever with. This is my first engine build and I want to build it for twin turbos and put it in a cat eye 1500. If anyone has any advice it would be much appreciated.
That's awesome! Basically, copy this and get a forged crank, different cam, lesson the compression to like 9:1 or so and strap the turbos on. Thanks for watching!
I love watching your videos while I eat delicious Goya products
Glad you like them!
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 a 1999 Chevy silverado, 5.3 liter, vin T, LM7 engine with a bad cam gm# 12560966. Can I replace the 1999 cam with a 2000 gm# 12560967 cam? Would any re-tuning reprogramming be required?
I just got my 5.3 a couple of days ago, I'm having issues getting the torque converter off, cause the bolts are super tight and don't think they never been taking off. You think if I was to use a breaker bar that would work?
Yeah that would work for sure. Thanks for watching!
You have just given me way more confidence and knowledge to rebuild an old 5.3 out of a 98 obs I just have laying in the driveway. Any recommendations on engine stands? I forgot the name of the crane/cherry pick I have if compatibility matters
Very cool! I really like the Summit Racing stand we use, you don't need to break the bank. However don't go too cheap either. I like this type, due to the way the legs are amzn.to/3eXwZ89
Thanks for watching!
Trucker Ray here. Thanks for the lesson on faze1. I'm convinced that the 5.3 is going in the engine bay of my 1962 C10 Fleetside Shortbed Big back window. Teach on. How do I follow you. Trucker Ray ✝️
Nice! Just click subscribe and you are all done! Thanks for watching Trucker Ray!
Whats your thoughts on using a carb and the msd 6ls box conversion for this build?
In my opinion it kinda takes away from how nice it is to have fuel injection and just starting on a dime. BUT if you have a legacy build might fit the build better. It would kinda look like an old school small block. Thanks for watching!
Thank you for this Great Video, I am a First Time Chevy Truck Owner and It's a Beauty. My Engine looks a lot like the one in your video but how do you KNOW that you have an LS Engine or not? I have the 5.3L.
Thanks so much for watching! If it was 1999 and newer it is a LS or an LS based LT.
Ok I have a lowrider I have a Ls 5.3 and I'm putting a stage 2 cam but I don't want it to sound like a hot rod how can I get it quieter
I'm about to start this very same build on my 2000 silverado any advice what look out for and im continue watching rest your videos
Just save all the parts you take off. Also, the headbolts are torque to yield so throw those out. Thanks for watching Greg!
Just so you know, I have a 5.3L engine in my garage, Just "because" of you. I paid 300 CAD for it. It's in good condition, and I am at the machine shop state and buying part state. And it's the first time I did work like that, the first engine ever, and I have a unique plan for it, like a mustang gt500 supercharger on my ls ;p. Thanks for making that series of videos; I must have watched it at least 3 times. But don't laugh; I've undoubtedly missed the part, in every ls video, on how to remove this #$% fan with a clutch on the water pump; I tried every tool, heavy tool, cutting tool, and I can't remove it. Now it's just a question of pride and easy packing for the metal scrapper. Everybody must know "how to hit him on the nose" to separate the two damn things. I'm afraid to search to see how stupid I am ;p. Or mine is stuff beyond anything. It will have an electric water pump instead.
Very very cool! When you finish it up send me a picture, I'd love to see it! ryan@2carpros.com or on instagram @ryansgarage408
If the fan clutch is truly seized on there, just remove the entire water pump. Thanks very much for watching!
@@2carpros Will do for sure
That is one big ass crescent wrench😂😂😂
I just bought a 04 suburban with the same engine whole truck for 500 bucks only needs break lines got 180 on the motor i checked the oil after 3 months an it damn near still looks new
Nice work!
I'm doing the same thing, got it from 04 Chevy Suburban, I got the tras too but it's 4x4 any way to switch or modify the tras case end for 2wd
Yes. You just need the extension housing on the output shaft. Thanks for watching!
Hey partner great video. Can’t wait to see the second part. My question is did you remember to fish that washer out of he intake that dropped down in there and how did you do it?☺️
Good memory. I actually went and fished it out just now. LOL! I used a little hook tool. Thanks for watching!
I’ve watched the whole series a few times now. I have my 5.3 ready to disassemble and start the process. My question is if I do the same exact build will I be able to tune it for a daily driver or will I have to use a different cam? Thx
Nice! Yeah you will totally be able to tune it for a daily use. It just won't make as much power as we did. You might want to take the compression down to 9 or 10:1 or so just so it runs on pump gas a bit easier.
@@2carpros thanks a lot for your quick response and great job explaining everything on your videos. One of the best series I’ve see on UA-cam.
Does this seris apply to the gmc Yukon 5.3L vortec 8v 1500 ? Cuz i wanna rebuild mine n this engine is similar to mine , but i guess theres no LS engines with yukons
Yes, I'm pretty sure that is the same LM7 we did here so it totally applies. Thanks for watching!
Thank you for these. My pops passed last year and left me a 2001 Sierra SLT z71 4x4 with this exact motor, just about the same mileage with a little lifter tick when warming up too. Wasn't sure what to do with it.. Might take a stab at this now and try to restore with your detailed explanation & hopefully a buddy with the other tools I don't have lol. KBB says it's barely worth anything as it is. ¯\_(ツ)_/¯ Cheers bud, GodBless 🤙
My condolences.
I'm sure he would love that! Thanks for watching!
Would you apply this same tear down and rebuild on an lq4 or is it different? Besides the cube difference?
Oh yeah definitely. Very very similar. Wish we had a LQ4 but the LM7 was a lot cheaper off ebay. Thanks so much for watching!
Love your videos and I havent found any better on UA-cam for instructional purposes. I found a junkyard lq4 for 200 dollars and couldn't pass it up. Keep these videos coming, we all appreciate your knowledge and willingness to teach. Have a great day and thanks again.
@@badgerrun8771 Thank you! That is so cool! What a steal! I would have totally bought that for 200. Even if I didn't have immediate plans. Such a nice block for 200 bucks. Let me know how your build goes!
I just got a lQ4 and have been following along while I take mine apart . One of the best videos I have found. I love how you call out what socket is required. Helps so much
I have a 2003 Chevy work truck 4.8 4l60e woth 350k miles on it. Motor knocks and tranny slips. I had the 4l60e rebuilt and bought a junkyard 5.3l not as old. Truck runs brand new! 5.3l has obvious more power than my 4.8l. 😅
17:45.... I'm sorry, knock sensor preventing noxious gas?? Or are my ears not working.
Ryan where is the best place to get a engine hardness for the lm7
Good question! Go with www.bp-automotive.com/ they are the best. Thanks for watching!
So I’m going to rebuild this engine in my 04 Suburban. How exactly do you remove the engine from the vehicle itself?
Great question! I've done a full tutorial on this channel but with a 1981 Bronco, it will be very similar. Thanks for watching Randall! ua-cam.com/video/zy1CozLgWUQ/v-deo.html
Bolts were too long on engine stand for me. had to use three ac compressor bolts and used one of those long bolts with a ton of washers.
Watched your video on LM7 build, great work. Got a question on costs comparison. I priced out your components last week with Summit Racing. it added up to around $8k not including the cost of a machine shop. Based upon the hardware that you used. just curious what the costs would be to purchase a similar engine already built thru summit racing or other sites. I feel like I have enough experience to do this type of job, but is the trade off worth it.
Thank you
Was less when I did it. Inflation has really done a number. I know you can buy a cheaper engine prebuilt from Summit and that's totally a cool way to go but if you wanted to do it yourself this is the way to go. Thanks for watching!
I have a 2004 GNC Sierra 1500 4WD with this motor and my question is about my 4L60E transmission. I clearly don’t believe it would hold up to this build. Can I use the original transmission and have it rebuilt to withstand that beefed up 5.3 or do I need to upgrade to anew one and if so what would you recommend??? Also, would the transfer case need upgrades as well? And one final question can all of the OEM front accessories go back on as well as the original wiring harness?!? Because, I will be doing this build for the truck it’s in and using it to pull a 7x12, two axle box trailer for my yard company…
I believe you could have it beefed up but for the money you might want to just go with a 4L80E. As far as transferase upgrades go you can just get that beefed up and it would be more than fine it is a good unit. Yeah all the accessories will bolt up and everything should plug in, you will just have to figure out how to mount the MAF sensor on the intake tube but that is easy peasy. Thanks for watching!
@@2carpros Thank you very much for your reply. Just to clarify, I can bolt up a 4L80E without any modifications? Also, are we talking just a bare stock one or an HD? And should I buy a new one or just find and have a used one rebuilt? Again, thanks for the reply and I will be looking forward to the next one!
Yeah mine was free.99..... Happy Birthday to me 🤣🤣🤣
I have a 5.3 out of a 2002 GMC Sierra is there any difference between my engine and yours
No I don't think so. This was a 2001 LM7. Thanks for watching!
I'm upset that you can find so many rebuild videos on UA-cam for GM 5.3L
But when you search Ford Triton 5.4L rebuilds the listing is very vague. Can Anyone offer some assistance?
Great question. The 5.4L Ford 3v is definitely a dark spot on Ford's engine history. They have tons of problems that can't really be solved without a large amount of work so people tend to stay away from them. I have a 2005 Ford 150 with the 5.4L 3v that I got for very cheap knowing I'd have to replace the engine at some point. If we do rebuild that engine you will see it right here on this channel BUT it will be a stock rebuild since there isn't any cool parts for it. Thank you so much for watching!
Yes I'm aware but the 3V Triton has a lot of Power despite its many issues. Some engine rebuilders will try to customize certain oil passage ways and galleys to allow more lubrication to the cams. I still see a lot of them today in the shop I work in for just simple routine oil changes. I'm very excited to see the video you have for the 3V Triton.
Where can i get long enough bolts for the engine stand to transmission?
Check 6:22 in the video I go over what the bolts are. You can get them at any Home Depot or Lowes. Thanks for watching Robert!
@@2carpros thank you for the great videos
Would you get custom harness or go holley terminator
I would go bp-automotive.com/ for all of that. Thanks for watching!
Great videos? Question what was the approximate cost of this build?
It was about 7k without labor, thanks for watching!
Was that a gigantic flat head screw driver you used to walk the plate off? It started out a gag and turned out to be useful 😂
Just part of my toolset and hey if it works it works. Thanks for watching David!
What is the cost of rebuilding that 5.3 engine? I want to rebuild mine.
I was wondering the same thing buddy. I have an 06 chevy silverado with 186,000 on mine. Runs great but want start pricing the rebuild cost / labor
do you have a parts list for this build that you used
Yep. Thanks for watching! www.summitracing.com/newsandevents/newproductreleases/2carpros-5-3l-gm-ls-engine-build-parts-combos-now-available-at-summit-racing
What impact gun is that in the beginning?
That is my Snap-On 3/8 pneumatic impact driver. Thanks for watching!
Me & brother are about to build a ls i need some pointer disassembling it
Then this video series is perfect for you! Thanks for watching!
Those coolant lines you removed are for getting air out of the system
Right, to prevent hot spots on the heads. Thanks for watching!
Hey it’s me again! I’m currently working on my 4.8, I am not doing a full rebuild, but I am looking to maybe swap some parts, and add performance parts. I do have some questions in mind, am I able to get in contact with you for help? More then willing to pay for services

So is this a cast iron block 5.3? Also- how did you determine that it really is a 5.3 and not a 4.8 since they're identical externally? I know a lot of folks are out there selling 4.8's and saying they're 5.3's. I think there is a number code on the block?
Yes it is a cast iron block. The VIN of the truck tells me it's a 5.3. But it is always a good idea to double check.

So nice of you! Thanks for watching!
My 01 with 200k is looking at me anxiously 😂😂
It's ready! Go for it!
What size bolts to lift engine with hoist?
10x1.5mm for the sides of the cylinder head. You can also just use the exhaust bolts for the flange. Thanks for watching!
@2CarPros Thanks you. Appreciate it alot.
How do I get summit to sponser my 5.3 build
I got lucky! They saw the 454 build I was doing and wanted to help out with the next one. Thanks so much for watching!
Hey man what do you think the total cost of the rebuild was?
If you replace everything like did it was like 7000 or so. Thanks for watching!
@@2carpros of course! I’m trying to convince my dad to let me tear a party my 5.3 you’re videos are gonna be on the whole time haha
I need help building one just need to know what parts work together
Everything I've linked in the videos work great! Thanks for watching!
How many horse when completed rufly
And how do I find the links
I started to do mine as far as disassembling it. I have a stand from Harbor freight and those bolts don't work with it, they are too long
Cut them or get shorter ones, my stand has a bit thicker apparatus than most. Thanks for watching!
@@2carpros yea i've watched your vids now a few times now with my dad. By far yours is the most detailed. I will def be following each vid for the rebuild. I plan to put the lm7 in my 2002 trailblazer. Ive got a long road ahead but im confident i can do it, it will be our 1st build!
@@sheldonkowlessar7591 Awesome! Sounds like a super cool build! Let me know how it goes! If you do follow our built to a T, just note that the valve covers I used in the video are wrong, the ones I linked are correct. They are a bit taller and allow for the roller rocker clearance. Thanks for watching and have fun!
@@2carpros i havent decided on what rockers im going to go with yet. I have a lot of parts saved in cart on summit. i originally planned to reuse the stock ones but i saw some weird wear on 1 push rod so i will def change rockers. Im not going too crazy on build just want tit to be reliable because it will be my daily again. Thanks for the info and tips
“Knock sensors” not NoX sensors. NoX is produced by diesel engines.
It's an ENGINE! motors run on electricity.

Where can I️ buy a motor and have it shipped to my door for 500?😂😂I️ can’t find a lm7 near me for less than 900 and it won’t come with all accessories
I fear I may have influenced the market a bit. A lot of people bought them off eBay sending the price higher. But this one was 550 shipped when I bought it it was 2 years ago now though. Thanks for watching!
