350 Chevy TBI 5.7 Engine Tear Down / Rebuild , Video #1
HTML-код
- Опубликовано: 28 авг 2024
- This video was made for the enthusiast and or hobbyist. The engine is a 1993 light duty 350 (5.7) TBI (Throttle Body Injection) , it is not 34 years old as initially stated in the video , it was checked after I published the video. There is a couple minutes loss of sound at approx 1hour 6 minute mark and a song from 1:10:10 to 1:13:30 ( I apologize) to cover another copyrighted song as I had the radio on and picked up some Copyrighted Content ( song's )by mistake. I did try several times to remove the songs with no luck.
Pulled the exact same engine out of my 90 C2500. Crank had so much end play the counter balances were eating into the caps and block and ruined a flex plate. Couple of the bearings were starting to 'blue' from heat, but never spun one, had almost no cross hatch in the cylinders, less then normal ridge ring for having 300,000 miles on it, always fired right up, used 1 quart of oil between the 3000 mile oil changes, but was down to 13 mpg which was why I pulled it to give it a good look through. Got the truck used and drove it and maintained it for 5 years before yanking the engine. Even when they're 'bad' they're still good.
I’m a Chevy and square body guy . The engines and mechanical side of things i have never really known . One thing I’ve noticed while watching you do this. You’re observing it by its markings and features and addressing its history and Authenticism . As a firearms guy . I’m down with that and I’m going to learn about engines . Thank you for your video
Thank you and thanks for watching , I appreciate the comment!!
This is excellent. Thank you for taking the time to film all of this.
Thanks for the reply , I hope it was helpful.
@@jaysgarage3616 great video

Sir, you are one of the better instructors on RUclips. Very experienced in engine rebuilding.
Thank you for the comment John!!
Thank you so much for your very kind and well explained breakdown. I am (finally), re-assembling my '99 Suburbans engine manifold. am 57 years old and really (needed and wanted) to understand the deeper aspects of the engine, as I have never understood it. I now know what the main seal is, what a 2 or 4 bolt main is, what it means to have a spun-bearing and understand what the timing chain is turning. Thank you, thank you, THANK YOU!.
Thanks for commenting!! And thanks for watching! Glad it helped.
I'm about to do my first rebuild of a 350 I have been working on my own tractor trailers and machines and my whole life and I never did a rebuild of a gas motor and this is the exact motor I am going to rebuild you are teaching me a lot right now
Sir! Your opening comment was you have never done a video! Well! Very impressed with your attention to detail, the way you show how everything is taken a part, what to look for.I have never taken an engine apart. I have been debating on pulling my engine from my project 1987 Chevy K10. After watching your video ( going to watch more of your videos) I am going to attempt it. I like how you keep your work space organized. Thank You Jay! Please keep making videos for guys like me!
Thanks for the comment!! And thanks for watching!. More videos coming soon. Good luck with your project , I'm sure it will be just fine!
Looking forward to watching this. I just pulled a whole TBI 350 and 700r4 out of a 89 blazer for $100
Thanks for the reply , hope you find something in the video helpful.
About to rebuild my 350 tbi on my 89 k5 blazer, that I've neglected to restore the last 10 years. This video gave me the kick I wanted/needed to just get it done over a buying a crate engine. Put a new l33 in my silverado 5 years ago and couldnt be happier. Thanks for the content. Got a follower from me
Thanks for the comment and thanks for watching!!
I'm glad that I found your channel Mr. Jay! You clearly have quite a bit of experience rebuilding these chevy small block engines. Thanks for sharing the adventure with us! Fred
I am glad you liked it , thanks for the reply Fred!
What is the gap on spark plug 4 point3 gmc
just bought a 1 owner, garage kept, 136k mile 93 caprice wagon
Excellent teardown, thank you. time to get to work!
Good find James , thanks for watching and good luck with your rebuild!!
Thank you. I am currently trying to get a 91 k 1500 back to reasonable shape. At some point gonna do the motor. I appreciate how in depth you are
Hi , thanks for the comment and good luck with your truck!
Great video. Glad you took the time to record the entire tear down. Looking forward to the reassembly video!
Thank you for watching.
Sorry to be so off topic but does someone know a method to log back into an instagram account..?
I somehow lost the account password. I would love any tricks you can give me
@Layne Sawyer instablaster :)
@Randy Elliott thanks so much for your reply. I found the site through google and Im trying it out now.
I see it takes a while so I will get back to you later with my results.
@Randy Elliott it worked and I actually got access to my account again. I am so happy:D
Thanks so much you saved my ass !
My suburban threw a rod last night, thanks for the tear down video so I know what I'm getting myself into.
This is a man who knows his stuff great work 👍
This is the most in depth video I've found so far. Thank you!
Thank you.
Your video has a TON of useful information. Thanks for making it!!
Keep up the good work.
Thanks Ron!
Thank you for taking the time to do these videos. I’ll be staring a project on a TBI 350 and this will be extremely helpful.
Thanks for the reply and good luck with your build!!
I have that exact same motor in my 94 chevy pickup. I also plan to do a tare down and rebuild. I am still a bit green when it comes to working on my own vehicles. Videos like this are invaluable to my education! I am watching this video from start to finish and will learn soooooooooo much about working on my own 350 tbi. Thanks for making this content! I am now "liked& scribed"😊👊🏽
Hi , thanks for the reply and subscribing! We will have an assembly video coming as well in the near future.
How did it work out?
I’m gonna pull my 350 tbi and this video is making me a little less nervous. Thanks so much seem like you know what you’re doing and seem like a cool guy to be around. Good luck and I hope you’re doing great.
Thanks for the kind words and thanks for watching!!
Excellent ! A+ very detailed step-by-step video can’t believe this is your first video , excellent work, you’ve set the bar on the way a video should be taken👍🏽
I look forward in seeing more of your videos thank you 🙏
Thank you for the comment.
*Likewise @Mr. Jay's Garage
I have a 1991 Chevy C1500 with the 350 and with 310,700 miles. Never opened up, same oil pressure from when I bought it back in 1998 with 93,000 miles. Never been opened up, still original in the heads and rotating assembly. Still only burns not even half a quart of oil to 3,000 miles. The 90s 350s certainly were well built and durable as long as you took good care of them.
Sounds like you got a great little engine there! They were quite reliable when taken care of.
@@jaysgarage3616 Eventually, when the engine starts getting weak, I intend to do a mild build on it with a mild cam and bore it out a little seeing the 700R4 tranny has already been rebuilt with a stage 1 B&M shift kit and can handle the extra power.
This guy has decades of knowledge here.
Unfortunately the younger generation doesn’t have nor want these skills.
This will become a lost art. Only those doing it for a hobby will continue but in very few numbers.
Thanks so much for this great video. I just start out to learn how to rebuild small blocks and your video helped a lot with that. Especially that the video is more or less done in real time and not cut down to the important things. It helps to get a feeling for time needed. Greetings from Berlin, Germany!
Thank you for the comment , glad it is helping!
Thank you. Just like everyone else has said. Thank you for taking the time to make this tear down. For your first video you did great.!!
Thank you and thanks for the comment.
Rebuilding the engine in my 90 GMC Sierra made in Canada in 89 thanks for the videos I’ll be using this as a guide
Awesome , thanks for watching and good luck with your build!
Jay, just hit that SUBSCRIBE button. Really enjoy your attention to detail look forward to watching all your videos. Instructional videos like this will help the younger generations.
Thanks 👍
If you're looking for a proper way to do this this is the video best I've seen on RUclips. Almost like watching my father do it. We always took a very long 3/16 drill and oversized the top oil galley hole above the camshaft. This holds more oil at the top of the motor. Then we tap out both sides of this plug and put a pipet plug with red thread lock tight. We also put a high volume high pressure oil pump on or we convert these by stretching the relief spring in the oil pump.
Thanks for the comment , it's always interesting seeing what people used to do or still do! Thanks for sharing!
Breaking down is very important for putting back together
I thought you did a wonderful job showing the in’s & out’s of a tear down on that motor you used ! I’m a retIered wrench myself and I stumbled on to your video and got stuck watching the whole thing.
One thing that I especially liked is you very smoothly drove home the good practice of ( NOT using the shaft of your 3 lb. hammer or the likes of a 1/2”or 3/4” breaker bar into a intake runner of the int.
Manifold to jar that loose
I appreciate the comment , thanks for watching!
You work so clean, thanks for uploading this. Hopefully all your videos are like this, long and not too much editing.
Thank you and thanks for watching!
Always wanted to do this. I'm gonna redo my 91 GMC with paint, interior and a new/rebuilt motor. Why spend 50 grand on a new truck when I have a kit in the driveway?
I'm away at work but the engine is still not ready at the machine shop , hopefully it is when I get back home this time. Good luck with your build!
@UCKgaCSZ5MWpUVv-2NdcxVqg yes...., "brother man."🤔
I've been there, done that...... The anticipation has to, SUCK, dingle berries, like sand through, CONCRETE! What sucks about the, "waiting game" is that it is the, SAME, For this engine as the last one, as well as the next, one!
The only thing that sucks worse is the FIRST, initial, "start up", when you/eye am as nervous as a dog schitting a, peach seed. When you KNOW that it only takes 1 bolt, rod cap, main cap, oil pump bolt, either totally, forgotten about, or improperly, torqued, & it's back to squar...... nevermind Gear heads know the, drill... hahaha... hehe. 😉✌❤💯
Good ol', "NEGATIVE Nancy doesnt get entertained by, me, my friend, ...... phuck that cunt! "L👁👁KING 4WARD to a ride along vidya, soon, brother.
My comment has accidentally run like, diahreaa, "Again", THANK YOU, DEARLY, for your time boiz & goiylz!! "IF YOU'RE STILL WIMME? You are the, "Beez kneez!"
❤❤❤
Put down the pipe and move away,
@Clay Green
Doing the same thing with my 93 K1500. I have redone most of the interior.. My new 40-20-40 front seat will be here in May and then it's just little odds and ends to finish up the inside (glove box door, new map/dome light assembly, color matched sun visors, etc..
Just took the 350 short block to the machine shop yesterday to get cleaned, machined, new pistons if they decide to bore it out (355) new cam/main bearings, threaded oil galley plugs, new freeze plugs, and they're gonna pop in my new cam and timing set for me.
Final setup will be:
350 or 355 with 906/062 iron vortec heads, 2.02"intake/1.60"exhaust.
Comp Cams XE256H flat tappet:
.449/.456 lift, 212/218 duration (@ .05)
112° LSA
Long tube headers, GM performance TBI Vortec intake, gonna keep the factory throttle body but rebuild it with new injectors and a 13lb regulator spring.
Probably other shit I'm gonna do but I'm off to a great start. I love these 90s GM pickups.
And how did 50 grand turn into 80k $ for a pickup truck?
Great video. Looking forward to reassembly .
Thanks for the reply. We had one here but it became time sensitive and was not possible to film , I really wish I could have but I have the engine from the video heading to the machine shop soon and we will do that one hopefully this spring. It takes a few weeks to get anything done it seems.

Loved, loved love video, You do and it shows, the experience even handling parts amazing throwing all those parts in plastic
bin that would kind of freak me out Think I would have to tag and bag just being afraid of not getting the proper bolt
back in place..really love this about to watch rebuild or PT2... THANKS FOR TIME/EFFORT....
thanks for the vid i learned how to rebuild engines for youtube alone thanks to everyone who makes these videos. Larry B
Thanks Larry , appreciate the comment.
Brother. I wish I could fly you out to AZ to redo my engine. The way you know your engine in inspiring. 🙌🏽🙏🏽
I wish I could go there! Thanks for watching!
Just got an 84 Camaro with no motor so we r taking one of these out of an 89 Silverado. Should be fun iv never been good with cars so new learning experience
It can be a lot of fun , good luck with the project!!
Love your tool boxes
Thank you!! Thanks for watching!!
well done. finding your video is a great surprise ! Just started looking at my Chev 5.7 - 350 so this will come in handy, Thank you!
Thanks again!
I got same 86 TBI 350 im putting in a 64 Buick LeSabre but i stripped all the front stuuf off even the fuel injection carb to switch it all over to old school setup aka 70s down so i got everything thats still good for sale cheap even the alternator id take $90
Chevy 350 is as American as apple pie 🥧 and base ball A Legendary workhorse! 🇺🇸
I think many would agree with that statement!
You make it look easy but I’m still afraid to tackle this by myself. Great video. Cant wait to watch the second part.
You will be fine , just take your time.
Thanks I will be tearing down this exact engine. Nice walk through. Cheers.
Glad it helped , thanks for the comment
Have the same motor in my 94 c1500 with 307,000 miles on it using little oil now wanting to do a rebuild on it good video
307000 miles is awesome , good luck with the rebuild!!
Cool video it's been a while since I did it , 25 yrs or so .😊
Thanks for the comment.
I don't have words to describe it, amazing job.
Thanks Man!
Those TBI engines can make decent power with nothing but a cam swap , we did one with what they call a TBI power cam from Engine Tech and it made 320 hp which it good for a TBI 5.7. Really good video.
Thanks for the comment , I will look that cam up. We will be debating cams when we reassemble this TBI engine which is currently at the machine shop.
A cam swap for an additional 130 hp? I’m calling BS. The primitive, by today’s standards, ECM on these engines, (350 L05) severely limit what you can do and still have the engine properly function. The cam you refer to has to be able to work as a whole within the limits of the ECM. While I’m not familiar with Engine Tech, or the specs of the cam you mention, there are several well known cam grinders that have an “RV” cam that is designed to work with the existing limits of the ECM, TBI, heads, and C.R. of the 350 L05. By itself, the cam might be good for maybe 30hp tops.
@@bondpit8750 I'm trying to do this very thing: eek as much HP as I can from my original TBI 5.7 while not upsetting the stock ECM on my 1987 Chevy Silverado. Unlike the 727 block in this video, my 5.7 TBI block is "roller-ready". So I was planning to put the newer (90-96ish?) L31 truck roller cam in it. But leave most everything else alone. Do you think I can get 25-35hp just from the cam swap and still keep my stock ECM happy?
This helped me a lot I’m about to tear mine down when I go back together gonna need the next video hopefully some info on cams and possible heads to get a little more power thanks
There was a teardown and 4 assembly videos followed , stock build. Will look at some performance stuff in future videos. Thanks for watching!
The actual stamping on the water pump boss passenger side would tell you more than the casting numbers you reference in the beginning. Those bearings looked typical for an engine that sat that long. I didn't see copper on any of em. A couple old straight plug boots go a long way when your messing with rod/piston removal/installation to not gouge the crank.
Thanks for the comment Bo , I thought we went over that in the video? It was an April fool engine .
Thanks for the explanations 🙌
Anytime!! Thanks for the comment!
You do good Sir.
Great video and all the best to you and yours Sir.
Thank you very much and thanks for watching!!
Awesome video. Wish I have that garage and tool kits to restore my 96 chevy
Thanks for the reply. That took years to assemble that box.
Kind of liked the music actually. Mind you I was a rave kid in the late 80s and 90s, and still hit the festivals every summer. In this video the music is such a complete out-of-the-blue surprize that it made me laugh out loud.
Also, its a good video, the only thing I would change is that the engine should not have the balancer face the camera, turn it away at a 45 degree angle so we can see what you'redoing.
Thanks for the comments. I do think the positioning could have been better after seeing it.
good idea is to grease your puller shaft and moving parts to extend your tool life.
Thanks for the tip Brian.
I have a 93 5.7L 350, i want a 355ci build with high torque.. 5.7L is in a 4x4 93. The idea is too to rebuild the motor to 355 specs, swap rear inards and make it an awd truck. Lot more complicated but its what i want at the end of the day
Sounds like a neat project! Thanks for watching!
Great step by step video! Thanks and all the best.
Thanks for the reply!
Very well done for your first video mate. Learned a lot.
Thank You!!
You should use a separate piece of cardboard for bolts etc for each part tbi, pulleys etc. if you throw them all in one bucket chances are you will forget what goes where.
You should be able to install a roller cam and roller lifters for reliability. I installed a retro roller cam in the 350 of my '73 Nova. Check around to see the parts needed for your block.
Not a bad idea , thanks for the reply!
My TBI came from factory drilled and tapped for a roller cam. A LT1 cam and vortec heads really wake these TBI 350’s. Just need to get a new tune in the ECM and your golden
You should fill the cooling system with water to make sure the block is not cracked.
I never thought I'd could learn so much about a Chevy 350 in such a short time. I'm no mechanic and would never do this myself, but I need to know what all the parts are when talking "rebuild" on my boat engines... Thanks!
Thanks for the reply , I'm glad it helped!
Bro how is no one mentioning the paper towel in the block....? No wonder this engine was auctioned, imagine doing all that work just for it to slodge and spit and misfire kus of a paper towel lmao.
Hi Jay, I'm a Jayson also lol. Stumbled accross your channel and just subscribed so keep up the good work🍻
Thank you!
Enjoyed it, I own a 91 Chevy C-1500 5.7 that I want to rebuild and add a cam, and vortec heads.
Thanks for the comment Todd and good luck with your build!
That's the old 200-210hp 350 you could put a set of vortec heads and true flattop pistons and bring that up to a little over 300hp
whats better.. 93 caprice ltz... or 96 caprice 4.3 v8 ?
What a great guy. Thank you
Thanks!! I appreciate the comment!
Thank you for responding back with my question with gasket missing between the throttle body and intake. My other question is what could be causing my truck sometimes bog down when I push down the paddle to give it gas Could the missing gasket from my first question causing it or could the catalytic converter be causing it to bog down like it's not getting enough fuel I've changed fuel pump, filter and everything I could think of relating to fuel
i have a 350tbi in my 95 suburban c1500 i'm gonna be rebuilding er
Great video brotha appreciate it
Thanks for the comment!
Thank you this video help me a lot
Thanks for the comment and thanks for watching!!
Great video 👍
Thanks for watching!!
Had me tripping all over when that music came on at the end lmao
Haha , It was bad!
Thank you for this great video
Hey , thanks for the comment!
RUclips gold mine ! Thanks :)
Thanks , hope it helps.
Good video to show and learn off of
I hope it helped , thanks.
Great video thanks you
Thank you and thanks for watching!!
Looks like she got 🔥
Smelled like it as well , the core was actually pretty good overall considering how it looked coming apart.
I own a 1995 Gmc sierra she is at 350,000 miles,
I have a lot of questions,
Since i see that you have a looooottt of experience,
I want to rebuild my engine, but i want to make it a bit more beefer
727 is already a hydraulic roller from factory.
Thank you
Thank you for the reply!!
Great video...the song threw me off big time towards the end haha..very informative and groovy.
love your video! I am hoping to get your opinion on something. I have a chevy 350 that I want to freshen up without machining. I specifically want to replace the main and rod bearings to increase engine longevity. So regarding the rod bearings, can I just replace them, do the clearance checks, and retorque them without having to change the rod bolts/nuts? Its just a stock, average HP late 70' engine that is just a daily driver. Thoughts on this?
Great job. Very informative. Question, did you send the block to the machine shop or just the crank? I didn’t know if it needed line boring or no?
Hi Larry , The engine was sent to the machine shop , Block, Crank , Rods , Heads. I have a 4 part build on this engine if you can see my other videos. Thanks.
should have removed intake manifold in reverse order of torque sequence. same way with head bolts to minimize warpage.
Doesn't matter when removing it only matters when torqued
Yeah every weird RUclips mechanic says that exact thing, it doesn’t matter on disassembly.
That missing gasket is a dead give away it was a kids truck. They had a spacer in there then removed it. You should of numbers your intake bolts, you gonna regret it.
Thanks for an awesome video.
Thanks for the reply!
good video ! thanks for the info !
Thanks!, appreciate the comment.
My aunt just gave me my uncles 1991 gmc sierra has the 5.7 but it knocks so much im just gonna replace the motor once it blows if it does i know they are very reliable
They are , good luck with the swap and thanks for watching!!
I wonder how much power I could make out this motor ?
Sweet Video!
Thanks man!
I sure could use a neighbor/buddy like you! Have a small block 350 needing re-build lol whereabouts are you from?
Small town Saskatchewan
Thanks for uploading. I have just put my 350ci on the stand and am wondering how far I should go with the take down.
Thanks for the reply and thanks for watching!!
GREAT VIDEO!
Thanks!! Appreciate the comment!!
Wait, I think you just solved my wiper blades problem
Glad I could help.
Hi, I know this video is old and you probably won’t see this. But I’m rebuilding my 94 gmc c1500 engine. It’s a small block 5.7 350 tbi like that. What rebuild kit do you recommend?
Hi , I did not order a kit , Rockauto and my local Machine Shop , Pistons , Cam bearing , Main and Rod bearings , Rings , Core Plugs from Machine shop , gaskets , cam , lifters , rockers , oil pump etc all came from Rockauto. Hope this helped and thanks for watching!!
i have a 92 chevy Silverado. that has the cooling connection at the passenger side on the intake of a tbi that the threads are gone can they be retreaded?
Thank you. This is motivating. Where would you suggest finding an engine to start a project like this
I bought this at an auction but a wrecker , or a machine shop as they check their cores. That might be the easiest , thanks for watching!
43:51 I have a set of 191's that are 64cc, mine have a triangle symbol at the valve cover face on the end of the head upper , i'm thinking the 191 came with ether chamber size ?? i think if you want the roller block you have to look for the 5.7 that came from a 1500 series i think the 2500 and 3500 trucks got the flat tappet blocks, id like to hear what others reading my comment have found......
It is interesting hearing what others have seen , maybe some will chime in on their findings.
Got a 90’s model single cab , about to start trying to rebuild the motor and i dont know what im doing 💀 we will see
Good luck Seth , there are 4 videos rebuilding this engine you could follow if you like. Thanks for watching.
Amazing video tons of useful and helpful info thanks alot question tho why would my chevy suburban 96 5.7l be stuttering in take off I rebuilt the trans and was told it was good now would it be the cam sensor or crank sensor???
Hey thanks for the comment!!
Could be a tune up issue , vacuum leak etc. So hard to diagnose without seeing it , hope you get it figured out.
