This is why I watch a variety of people, everyone teaches a little something that someone else don't. Thank you sir.
I appreciate that!
I have a 91 chev 4.3 what roller lifters can I use were do I get over size valve covers for this application
@@PetesGarage Are 4 cylinders pretty much the same thing such as the honda civics?
Adept Ape is another great channel
Very thorough! Best video I’ve seen
Going back and watching these videos again after about a year.
Edit:I guess i watched them again about 3 months ago. Must be addictive.
There's always something to learn
Great video Pete, it's so nice to watch someone that actually knows what he's doing instead of the ones that "think" they know.
Thanks Craig, it's good to get a variety of opinions
Thank you sir 🙏
I’ve torn down the 5.7 HEMI to the block, for my grand Cherokee. These little videos are educating me on what I must do for the rebuild. I appreciate the vids. Keep ‘em coming.
Right on
Rewatching your videos again...it's giving me the engine building bug. I haven't built an engine in almost a year. I think I'm due lol.
Btw you were right when i asked about using STP as assembly lube. Used it on the last engine and no problems at all.
That's awesome! It's time for me too. I think people overthink assembly lubes.
Good question I always wondered that I saw a gentleman building a 1600 Vw bug engine and that's all he swears by half oil without detergent and STP say he's been doing it for x amount of year's zero problems.
Throwing 30 over pistons and rings bearings with a home job in a 400 sbc today. Haven't done it in 20 years . Good reminder video.
Glad it helped
@@PetesGarage yes it did bottom end all together. Was weird used the same pistons as you
great video man, thanks! you include a lot of details on the minor things that other videos don't cover.
Glad it was helpful!
The chamfer on the connecting rod faces the front of the engine, timing cover side
Attention to details is a must. Glad you are teaching that. Great job!
Thank you Keith

Thanks Pete. I have a 383 stroker engine that I had fully built in 2008. After putting it in my 1966 Chevelle, I moved away for college. I only drove the car a few times (less than 500 miles), but when I did drive it, I drove it hard. I was young and reckless. I am now 30 and got the car out of my moms garage in Illinois and into my garage in PA. After doing some assessment, I found 4 broken pistons caused by what I would assume to be detonation. Like I said, I drove the car hard and not very often.
These videos of yours are going to help me tremendously when it comes to fixing my engine. I know it would be best to have a pro do this, but TBH, no man should ever let another man touch his car without him present haha. And how the hell am I going to evolve as a Car Guy if my "work" is just opening of the bill fold?
Thank you for being a resource for myself and so many others!
Right on my friend....you gotta build it yourself
2 year old video but awesome to be here. very nicely done and good instructions and well explained. Thanks Pete's garage
Thank you my friend
God bless you pete.Very categorically done, kudos and thank you.Also you may just need to oil your piston insertion tool.
Thank you for this whole engine rebuild vid.
Thank you my friend 👍
Love how you show the whole process keep up the great work..👍
Thanks Rob, I appreciate your comment.
yeah, it's the little things that other people miss. i'm learning but i feel like i'd have better chance of not totally screwing up after watching this series
New subscriber, love your videos. There are very few people that go into good detail on the little things like you do and its appreciated. Starting two engines tomorrow and this series helps greatly. Keep turning wrenches man.
Thanks and have fun!
I’m rebuilding a Honda 4 cyl vtec and this was still very helpful. Nice video 👍🏼
Glad it helped!
Thanks Pete, looking forward to more!
thanks you solved my confusion how to measure it. I watched 19 videos no one explained that easily like you did
I'm happy to help
@@PetesGarage thanks
Thanks Pete, very thorough and helpful.
Glad it was helpful!
That was a great tutorial. Thanks a lot. Keith in UK.
Thanks my friend
I really appreciate the time you put into the engine build videos. I have restored many complete cars but never built a motor, or transmission. It is time my 61 rambler restomod gets a new heart beat. I was wondering if you have a video demonstrating how to file the rings if you do need to increase the gap and the tool you like to use to accomplish the task. Thank you again.
I do have a video about rings. It's on the last 440 build I did.
True teaching ability. Thank you
Thanks my friend
Great video, good info and interesting to watch. Thanks for a lot of the good tips, my only 2 cents are, yes "clicking" the torque wrench multiple times may move it out of accuracy faster, however if fasteners still move when you click it the second or third time then it is indeed torquing it even finer and closer to the mark. A lot of the machinery manuals I use at work specifically tell you to do this. First click is within manufacturers tolerance for the torque wrench (assuming it's been calibrated), sometimes that is pretty damn close to the money and it wont move after that on the same setting, other times it's 3-6 percent off on the initial click and will need additional clicks if you want the actual torque closer to what the wrench is set and calibrated to. Keep up the awesome videos though
Thanks for the comment
That was really helpful, I’m doing a z1000 , it’s daunting for me but that’s so helpful, thank you. And you’re a nice geeza. From Simon in the UK
Thank you Simon, good luck with that Z
I dont have a chevy but this information is good i tell you
Thanks Lawrence
If the opportunity presents itself, I would love to see a video on setting timing as well as how to break-in a sbc. I only ask because of the educational quality of your videos.
Thanks for the idea!
Best car videos Hands down
Thank you very much my friend
Just want to say I love your videos but the clicking the torque wrench twice is a good thing. I'm an engine and prop mechanic on C-130s and the reason you do this is because first off, there is oil in the torque wrench that causes deviation and that second click ensures the oil is moved inside the torque wrench. Second, all metal stretches. It's small but in my field absolutely measurable when you're applying 400 ft lbs to a mount bolt or Sweeny wrench. On the Sweeny you can see with the protractor on it the excess movement better first and second click. Obviously it's more noticable if you further bump the prop back and forth a little while torquing. I know this is only 40 ft lbs but I promise you aren't wearing out your torque wrench by done clicking.
But otherwise, thank you for the vids!
Great comment, thank you for sharing
Thanks so much brother. Regards
My pleasure!
Thanks for such detailed video
My pleasure
Your videos are very good.
Thank you very much!
Good point, I saw many people working with a torque wrench and tighten many times, that's wrong. It means over-torqued!
Torque wrenches are often used improperly.
outstanding video and appreciate how you show every step. i like the detail. show it like it really is. Thank You 👍
Thank you Arthur!
Great vid Pete 👌
Thanks my friend
Great tutorial. Thank you!
You're very welcome!
Very well demonstrated, thanks
Thanks Bobo
That was an amazing video. I love how you show the entire process: not skipping over valuable parts. I remember the first time I was putting a piston in and I hammered it as hard as you would to hammer a wheel stud out of a huge diesel truck, and afterwards, the piston was in, but the crank was totaled: $900. Dad was so pissed off
ooooooo, that was an expensive lesson.
@@PetesGarage Hello Pete ,Charles I bought a sbc engine from Summit it's a 4 bolt main , two piece rear main seal .
The problem I have is in front wear the timing chain goes the block has two holes that goes to the lifter's is that normal .
it's wasn't your fault, you are the learner, problem always the teacher.
Thanks you sir have learnt something
It's my pleasure
@@PetesGarage thanks
You are an awesome instructor. :)
Thank you my friend
Thank you great video very clear
Thanks Saul
Please note that sometimes pregapped rings maybe a little on the tight side. Its always a good idea to check them and may have to file slightly. I have encoutered this mostly with NPR rings. Granted they are cheap rings but they do fine for a budget build.
I agree 100%
You might try seeing end gap on the rings in their corresponding cylinder not all the rings in the same bore like you did. Better yet don't make a how to video on engine building if you don't know what your doing yourself
Thanks for a great video.
Glad you liked it!
Well said and done ✅
I subscribed 👏🏻👍🏻
Welcome my friend
Great videos Pete thanks
God job i like yours works
Thank you my friend
good video.. 👍 can't wait for the next one.
It's out!
Great video bud
Thanks 👍
Best video yet!
Thanks my friend
Thanks Pete
What about buying the right part for your car when entering registration number on dealer web sits
That works
This is called a four cylinder engine. 360/4 so 90 is the switch over point max out 45. Usually engine is a gas chamber pistons and a spin rod or shafts. Fire up and spin makes tyres rotation and gears to control rotation all others are directional moving controls. Like the steering wheel etc. Engine is one that is always sealed to make sure no damage and extreme care on assembly and misfire.
Interesting
How do you do this without a threaded crank? Turn by pushing counterweight? I got my crank in. I was thinking installing the crank gear early and using a homemade tool similar to what I used on bicycle cogs called a chain whip. Or maybe a socket with a slit to slide along the woodruff key. Or the balancer loosely fitted and with long bolts attached
I use the balancer bolt, it works great. All the ways to mention will also work.
You can use the plastiguage to measure rod bearing clearances correct?
Yes you can
Great video. BUT. A mention that on the even numbered cylinders, the piston carat goes forward but the big end chamfer is to the rear ( firewall) since #1 is against the fillet already. (not that some engines may not have offset pin bores and don't have a front -back orientation.) That engine seemed to turn nicely. Any idea how many ft-lbs to keep it moving after break-a-way? Thanks. - Sandy
Thanks Sandy, I did not measure it, but I do have a video about ring tension.
@@PetesGarage Thanks, I'll have to check that out. Currently working on a 340 GS engine rebuild; it had a wiped cam lobe - factory cam. Actually the automatic transmission is the coolest part. 2 speed but with a switch pitch, dual stall speed converter. Works almost like a 4 speed trans. My 401 Electra had a 3 speed with a switch pitch; called the Super Turbine 400 as opposed to the later TH400 -Sandy
That's sounds really cool, thanks Sandy
I have the same pistons and rods pete & the same rings but they check out around 10 11 thousands with a 30 over bore will it be ok
Did you check the thrust on the crank after it's bolted in?,
Absolutely
Gret Job, was a fun video, not eaxactly 2 hours but pretyy close, Id be lucky to get wheels and airbox out in 2 hours so a bi\ig Bravo Zulu ! (thats US Navy Submarine slang for great job)
Thank you my friend
Good
Thanks
Can u explain the how the alignment is made with the rings[How the GAPS are aligned?]
great video
Each set of rings comes with instructions on how to set the gaps
@@PetesGarage Thanks
That was awesome!
Thanks my friend
Do you have to use a “plastigauge” for the connecting rods?
Yes
Hey there. I’m doing a piston and rings on a 4 stroke dirt bike. The ring gap calls for a .04 to .06mm. What happens if the ring gap ends up being .08 to .10mm? This is all oem parts. Bike has a lot hours.
You will lose compression and leak oil
Can l used piston ring gab0.020inch top,0.025 second,oil 0.015 for my Hyundai Getz 2002 petrol
Great video. I'm just wondering, when you clock the rings and install them cant they just spin freely in the bore? Or are they so tight on the bore they cant?
They can and they will. There is always much discussion about this
@@PetesGarage i swear that I have seen little pins in the grooves on some pistons. But I might be mistaken 🤔
@@trailerpark187 You are not mistaken. You will find that two stroke engines (Marine, Dirt Bikes, ...) use pins in the ring grove to prevent the edge or a ring from catching a piston port if they were to rotate. A four cycle engine, such as this car engine, does not have piston ports to transfer air fuel from the crank case to the combustion chamber, so no piston ports exist in the cylinder side wall.
(Pete - great job, thanks so much).
I've got a question, the book's titles you wrote down in the description...what author?..i mean what specifics book?
You'll have to look those up
Am I correct in assuming that if I have my SBC block bored 30 over, then I can get a ring set that I don’t have to grind? Or, can I just get a ring set that doesn’t have to be ground no matter what? Thank you sir for always answering questions, responding and being one of the best channels out there.
Yes, if it is truly measured .030" over you can buy the set ready to install.
@@PetesGarage awesome, thank you!
@@kosworkshop measure everything🍻
@@whiplashmachine thank you! That’s a good general rule especially for someone new like myself. You do see a lot of videos of folks just building engines blindly.
@@kosworkshop yup, lots of slapped together projects out there. Then they often cost even more to fix. Every year I see easily a half a dozen brought into my work to get fixed up because no attention or inspection was given. This year espesially, I have come accross many manufacturing or packaging errors from our parts vendors. Some of them would have been very costly errors had them parts made it into the engine.
I know this is old but my hyper pistons call for .026 top middle ring gap for street/strip. 0.14 is what you set it for. How come?
I followed the original specs for that year engine
don't you think it might be a good idea to check the gap on the oil rings?
You can, it's not a bad idea. If the first two come out of the box OK I've never had a problem with the oil rings. But you are right, they could make a mistake.
Hey Pete I was wondering if when you said .0035 ring gap for every inch of cylinder bore is standard for all naturally aspirated gas engines. Can you do a video explaining running gap amount for different power applications? Thanks again for your videos.
I meant to say "ring gap amount" not "running gap "
Sure, I can do that.
@@PetesGarage Thanks, I look forward to seeing it
I’m rebuilding a 2005 town and country 3.3 how many thousands I need in the rings my piston is not 4 inches they are 3-5/8 wide
Follow the directions of the ring manufacturer
U dint lube the piston ring and cylinder walls ??
Yes I did, with engine oil
Do you do gapiping the oil rings too or just the upper two ones ?
Just the compression rings
@@PetesGarage Okay, thanks. I have 2 do it on both upper rings. Pwy.
Awesome video, I’m following along with my 383 build, first build for me. I had a question, what ring gap would you recommend for a 383? naturally aspirated no more than 500 hp. My feeler gauge says I’m at .016 for 1st and 2nd. I see lots of different answers, but I really like your videos.
Follow what the ring manufacturer recommends
Any tips for how to avoid having the oil rings pop out before entering the cylinder?
Make sure to hold it perfectly flat to the block
Hii pete...
Can i repeat the same ring gap process for an 4 cylinder f8 engine...
& u did'nt tell about the other two oil rings what would be the gap size of them according to you...
You can, always follow the manufacturers recommendations on the box
Bro can u tell me manually how should i size the ring of my f8 4 cylinder rings i m Fitting NPR over sized rings in standard cylinder & standard piston cuz my piston was giving me a little play so i thought to put over size rings of 0.25 but i m confused in gapping them
When you buy the rings the manufacturer includes a recommendation on gapping them for different applications
@@PetesGarage yes i will chek over & thanx for guiding
Great video I have seen some builders put the rod bearings in dry,does it matter dry or with lube?Thanks
I always lube and part the will see friction
@@PetesGarage ok Thanks
Hey Pete, thanks for the great video!
I’m teaching myself mechanical stuff by working on an old 250cc one cylinder engine. Seems like I need new piston rings now after running a compression test. Was wondering if you have any thoughts on re-using the rod/bearings/bore/hone that is existing in a 30 year old engine. Trying to keep cost to a minimum.
Sounds great!
I am assembling a 351 cleveland and after installing the pistons it takes 35 ft/lb to rotate the crank. Is this normal? I checked the clearances and piston ring gap 3 times and they're good. I am using cast iron rings and clevite performance bearings on a standard bore and crank.
stock pistons and rods with the caps on correctly for sure (there are numbers stamped on the outside and they all are matching)
1 or more pistons are in backwards, chamfer on the rod faces the counterweight
@@PetesGarage They were all on correct but I took the pistons back out to verify everything was good and now its taking 25 ft/lb to turn over which should be ok if I remember correctly. Maybe I had some dirt in there
what are the implications of not lining up the piston's mark to the front of the engine?
It depends on the pistons, some are perfectly symmetrical while others are cut slightly off center. The valve relief in the top must line up correctly with the vales if you have those. The connecting rod will also be backwards with the chamfer facing the wrong side of the journal.
Total catastrofic engine failure.
could this be the cause for low compression and low power
It could be, yes
What type of ring filer do you use when gap needs widening
Summit brand
Do oil rings rails have up n bottom
Rails no, wipers yes
I have a 350 .040 over …. My gap is ..20 … what the most you can be? Tyia
Follow the ring manufacturers recommendations
im freshening up my sbc383 .030 with fordged pistons, eagle rods, dart heads etc and im not clear on the ring or ring gap i should run, i do plan on spraying it with 250hp shot. can you please give me your opinion on what material the rings should be and the proper gap?
Use chrome moly rings and follow the recommendations on the box for boost applivations
Aren't you supposed to oil the cylinder wall and the Piston rings before install?
I always lubricate the cylinders with motor oil
What's the gap for the oil rings?
And it will be for all V6 or V8 engines under 20?
I'm rebuild one 5.7 hemi for my 04 dodge durango
Gap should be on the packaging recommended by the manufacturer
@@PetesGarage thanks for replying!
@@PetesGarage I saw a video they torque the crankshaft at 21 + 90° turn
I did it but my crankshaft doesn't turn smooth like yours
I have to used ratchet to turn it it's little tight
One or more of your pistons are backwards
@@PetesGarage I'm still not installed the pistons yet
It's just the crankshaft by itself
Doesn't the crankshaft need to be balanced with the rod and piston head
They can be balanced separately.
my SBC is bored 30over to 3.905 and I am getting .029 on both 1 and 2nd ring. I should have the correct rings I checked the box and the part comes up 283 30 over. I used a electronic digital caliper and measured my bore at just around 3.905 Its not a bore gauge but it gets close. What should I do run at .029. I even went deeper into the bore inch checked another ring and another bore and came up the same. Max according to Hastings and SAE is .022 maybe I have bad chinese feeler gauges I think I'm gonna get another set but I can see being that far off by 6tho.
That is unusual. You may have to get a set of file to fit.
Hi , do you need to gap the rings on a completly stock engine with stock piston and bore? Can i just install the new rings or they must be gapped?
Not really, just check the gap to make sure they are ok.
@@PetesGarage thanks !
Great video Pete. I didn’t see you apply any kind of lube to the rings or bores. Just wondering if they all go together with no or light lube. If building an engine that will sit a while before starting does that make a difference too. Thanks
I always put WD40 in the top of the bore and in the ring compressor so it comes out smooth and protects the cylinder from rust.
I have a question. Would it matter is I pointed my top an second compression rings gaps up an down 180 from each other would there be a problem? I just popped the piston an rods on so I'm wondering is I need to change the orientation for my gap on a chevy 350 2 bolt main I'm rebuilding.
It won't really hurt anything
Thanks for getting back to me so quickly. Good to know. Thank you. Its my first rebuild on a stock chevy 350 truck motor. I helped yr's ago rebuilding motors with my dad. But its been almost 10 yrs since an my dad passed a way 2 yrs ago. Its all new to me doing the rebuild myself. Thanks for the help man.
The other day I put rings on and one slipped and scathed the piston. What would you do?
Depends where and how deep
Throw it all away and start over...kidding. you could always just buy a single replacement piston if you think it's a good idea.
Good video ... give chip a break😅
Hello Pete. I'm beeb ask to build a performance 383 sbc for a friend. It will be running on e85, and it will have about 550 hp. I have only build street engines before. Do you know what ring gap I would use? Or does it deoend on the manufacure?
Always use the ring gap specified by the manufacturer. If you have any questions, call their tech support line.
@@PetesGarage Thank you! Like your channel, great videos!
What if u miss a couple and put the dots downward how bad is this
That could be catastrophic
Could anyone tell me what size of ball hone I would need to purchase for a sbc 350 & a 305?
It should be a standard size
@@PetesGarage thank you! Got any new videos coming out? I have learned so much from you and I really appreciate all your teaching content.
I should have 1 today
Pete, if I have 4.380 is it × .0035 =0.01533. 15 1/3 ?
Yes, 15 thou is a good number
Awesome Korie
👍
How do u know the pounds of nut torque,Pete? Do different engines have different torques.
Yes, they are all different. It depends on the bolt size, base material, several factors
Buy a Haynes or Chilton manual for your vehicle, they usually have all the specs and tolerances listed for the engine.
YEAH!!!!!!!!!😎😎😎
