Easiest motor ever to rebuild!? DIY in your home garage! Part 1 Gen 5 LT L83 5.3L engine rebuild!

Today we have a video going over refreshing a 2018 LT L83 5.3L V8 engine. I try to cover all the steps so that someone could do this same rebuild in their garage! Below are the torque specs that I would recommend if you are reusing bolts.
Main bolts (inner and outer): 50 ft-lb
Main side bolts: 22ft-lb
rod bolts: 40 ft-lb
main clearance: .0018-.0025
rod clearance: .0018-.0025
top ring gap: .015-.020
2nd ring gap: .017-.030 (factory rings use large gap on 2nd ring)
oil rails: .025 min

Looks like a good setup you have. Looking forward to part two

[@paragonengines1924]

Thank you!

[@tjt4036]

Nice video, looking forward to part 2.

[@paragonengines1924]

Coming soon!

[@smokeysghost4759]

Good informational video…nice engine stand you have there

[@paragonengines1924]

Could do the job right without it!

[@georgetucker5631]

Great video. Very informative

[@paragonengines1924]

Glad it was helpful!

[@dunbarautomotive]

Nice video 👍

[@paragonengines1924]

Thanks 👍

[@FitzGaw]

Thanks for your time and information. Looking forward to part two

[@paragonengines1924]

You're welcome!

[@patrickwendling6759]

Thank you for your knowledge and video's USA 🇺🇸

[@paragonengines1924]

Thanks for watching!

The piston intention is sleekly for pooling fuel for start up.

[@paragonengines1924]

It is to help better mix the fuel and air in the combustion chamber for a more even flame front.

[@TMACWARDEN]

@@paragonengines1924 have you corrected the engineer that designed the piston?

[@auschalic]

@@TMACWARDEN I'm confused, is there something wrong with it?

[@TMACWARDEN]

@@auschalicnot at all- it’s literally designed to pool fuel and help with crank start

[@scudzuki]

A DIYer who does not have the dial bore gauge and micrometer (or the skill to use them) to verify bearing clearances could just get some plasti-gage. Also, if one is investing the time and funds to rebuild the engine, is reusing the TTY fasteners the right place to save money? The OEM screws ain't that expensive in my experience.

[@paragonengines1924]

Yes, plasti-gauge is one way to check clearance. Replacing the bolts is the best practice to use, but if you are trying to save as much as you can at home, reusing the bolts can be one of those ways.

[@scudzuki]

I wouldn't use the reluctor ring that you're indicating off of to pry the crank longitudinally. You're adding the flex of the ring to the actual crank movement. One could just as easily pry at another main cap.

[@paragonengines1924]

Fair enough, I was taking the measurement after the ring returned to it original spot.

[@Ruel-xq5hf]

Can i know torque specs for this engine for conrod bearing bolt,main bearing bolt and head bolts please! Big thanks in advance!

So is a 2020 l84 an lt engine or an ls engine

[@farncoisbisson7737]

Have you by any chance compare the crank and see of a 3.2xx stroke crank from a gen 4 4.8 would fit in?

[@paragonengines1924]

I have not.

[@MartinKellinghusen]

I have the same motor in my truck. Recently has begun burning excess oil. I believe is getting around the rings. I am strongly considering a refresh like this. Curious if you know roughly the cost of parts and the cost that you would charge to do this job?

[@paragonengines1924]

A refresh like this would run about $4K for everything you see in this video.

[@willkietzman1121]

you would happen to have all the tolerances would you? Id like a book and it seems like the gen IV rebuild manual will suffice

[@paragonengines1924]

I don't have gm specific tolerances.

[@beaumont9072]

America 🇺🇸 💪🏼🦅🛠️ What do you charge for a 6.0 full rebuild I want a soiled 600 hp going in a 96 jeep Xj?

[@paragonengines1924]

You could get 600 at the crank out of a 408. You would probably be around $10K+ for a build like that depending on how complete you want it.

[@Cracked1ce]

ls/lt main bolts are not TTY. they are only Torque To Angle

[@paragonengines1924]

Torque angle is the sequence you use to torque them. With that process, you are brining the bolt up to its yield point, hence "torque to yield"

[@Cracked1ce]

@@paragonengines1924 not all torque to angle bolts are torque to yield. Common misconception. A bolt is only torque to yield if it enters plastic deformation. The stock head bolts do enter plastic deformation, but the main cap bolts do not. They only enter elastic deformation. If you look in the AC Delco rebuild manual you will see that the main cap bolts are not an item that is replaced during a rebuild.

[@Azure_Zahab_Truth_Zealot]

What's the difference between a motor and an engine? I was told that engines are the combustion type and motors are electric. Which means all those years calling engine mounts motor mounts was incorrect, or things changed on us, I don't know, but we may need to relearn our vocabulary words. I still don't get it, because a motorcycle had an engine, but we call them motor-cycles. Next they'll be telling us 2+2=5 if not it's racist.

[@paragonengines1924]

Engine: a machine with moving parts that converts power into motion. motor: a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts. They seem pretty interchangeable to me, I wouldn't get caught up on it. English is a hard language.

[@Azure_Zahab_Truth_Zealot]

@@paragonengines1924 lol, English is definitely a hard language. Sometimes I think THEY're just screwing with us. Did you know the origin of "nice" is foolish, and blessed was about bleeding out or something like that. We have a lot of man-made traditions with very questionable roots. Anyhow, I'm rambling and totally off the subject of engines. Keep up the good work!
