please keep doing these videos, I learn more watching Jay explain things than anything else and its a lot of fun to watch.
At a minute thirty through the video I've already learned something new. Real Street Performance is easily my favorite car parts company.
Man!!! I get excited when I see these tech videos. If Jay had his own school I'd be there all day haha. Thanks once again Jay and the guys at Real Street, I have learnt so much by watching your tech vids. It helped me better understand what I'm passionate about though I never perused it as a profession.
This is the best information on measuing bearing clearances on the entire internet IMO. Awesome.
Excellent, and thanks so much! I've got a rod knock in an old 394 V8, and these videos give me the confidence to work through the job myself. And thanks for mentioning plasti-gauge. I was thinking I had to go buy expensive micrometers to do this.
I’d love to build an engine one day, but as my first built engine I’m going to have you build it. Great stuff Jay.
Lol🤣 watching Jay with these MANY teachings it's always a pleasure to many persons like myself who have a general motor vehicle knowledge .
Absolute best set of videos. Learning a ton, quality is top notch, no filler, all killer :)
I can't tell ya how much I appreciate these tech videos. Thanks Jay and real st!
Thanks uncle Jay. We would like to see a special video for spark plugs selection for 2jz
I can now assemble high performance engine with trust , we all owe you Jay
Thats an understatement.
Nice one thank you
This is EXACTLY the information I have been looking for. I'm going through this same process but with aluminum rods for my 1g DSM. First engine I've built but doing it right with all the right tools as well. I had no clue about bearing eccentricity. Thanks for the great video!

Jafromobile is an excellent channel for DSM builds, no flashiness, no BS, the guy is 100% transparent on his builds.
Always the best info from Jay
You are the man as far as all this goes ! Thank you so much !
Thank you Jay for the great information
OK, this is excellent, professorial. The gentleman explains as if a 5 y/o can understand, and it takes complete command of the subject matter do that. Nicely done.
Love ur videos Jay. And being a lefty makes more sense to your vast amount of knowledge in ur craft.
Thank you Jay & Real Street for putting this video into the ether. You guys are doing God's work with engines
Thank you Jay! You must have known I'm about to start building a motor. I might even call you guys for the pistons and rods as I've seen them offered from you site.
Same here my friend! I’ve got a Smokey FA20 WRX that needs some attention and real st has aalllll the internals 👌👌
@@TheBevis593 I hope you get it sorted quickly and with ease🤞👍👍 I am rebuilding my 08 2.3 mazdaspeed
Great now I want to build another motor. Thanks guys love these video. You guys are awesome
Like everyone has said, this video is amazeballz. I have access to all these tools and have been wanting to start building my own engines and this is a very big help to give me the confidence to do so. Thank you, and let’s fully build this b-series, huh? Thank you for the information. Hats off.
Very concise and professional. Your teaching abilities are stellar. Thank You !!!
thanks for taking the time to create these videos man, I'm currently beginning my first engine build, a 5.0 Windsor, I have been wanting to do so for a long time, now just gaining the knowledge, thanks again! From Australia!
I feel like we owe you $ for this video. There's lot of little bits of info in here that take years to learn the hard way if you're paying real close attention. This video is the best on the internet for proper measurement of bearing clearances.
awesome video. one thing i wish you covered was rode side clearances. keep up the good work you're killing it
WE LOVE YOU JAY ,VERY PRICY INFORMATION MAN.THANK YOU FOR SHARING BUD🙏
Thank you Jay!
This is great!
Best regards from the netherlands.
Great video guys. Never attempted something like this but this has been a very informative session.
Best teacher & Best content on YT !
Many thanks from France !!!
Your clear voice and speaking is a chance for foreign people as me.
Your sharing of top knowledge too !
Great job !
Love your videos, keep up the excellent work.
Great Video, thanks Jay
Thanks for sharing the knowledge
Thanks jay. Love these videos. I'm just about to put my k24 together.
Excellent video. Thanks for all the knowledge bombs.
Very informative!
Great job team 👏
Just bought a project sc300 factory 5spd with lifter tick, thinking of chasing some hp and this video was so informative to me honestly priceless educational
So good!! Thanks Jay…
Thank you Jay and staff for all your efforts. Presentation, facts and information are 2nd to none.
This is a good vid explaining it fairly simply Steve Morris also has a good vid on this same thing along with all kinds of other important tech tips laid out simple like jay does here
Man I am so excited for my B18C1 Build! Thank you so much I am humbled by the quality and exception care into the video and instructions given. Amazing Content and You Deserve a Bigger Following.
Nice engine indeed.
I love these videos and thank you for sharing
Thanks for sharing, very informative
Thank you Jay, can’t wait for moar vids 🤙🏾🤙🏾🤙🏾
Excellent
this is a great guide, i learned alot!
This is my favorite channel
Thank you for sharing your brain with us. Would be awesome to see you build a k20 from scratch
Super helpful thanks boss.
Awesome video.
Thanks you guy much appreciated
Great video very well done 👍
Great job thanks
Awesome video! I usually build v8s, so this was very informative on the slight differences between the two. I am excited to tap into the honda world!
Great content .I'm studying for an ASE test without schooling
This channel is goated
Jay wish I could get you to build my block. Your attention to detail is impeccable.
This process he's showing you is extremely normal for any 'serious' engine builder who knows how to correctly measure/assemble a motor. Jay's just showcasing it for you.
Great video 👍🏻
Thanks that was great
I had an issue with a huge dresser rand compressor. It was driven by a cat 3608. One of the brand new bearing shells was misboxed. We would have caught it if we had measured bearing crush. The clearance was correct, but there was no crush, and that permitted it to spin. This compressor was offshore, and we needed a crane to move parts around. It turned into a chore. Good on you for mentioning crush. Most people overlook it but it is important to know how to measure it on your application. I find it covers my ass to document it on my spec sheet.
great video you guys I'm in the process of rebuilding my first motor and it just happens to be a integra equivalent block. thanks ! Subscribed! also a customer
Great content 👌👌
You should open an online school.thank for sharing your knowledge.
As well as “keeping an oil pool” the extra horizontal clearance is needed during crank deflection, that deflection squares the bearing
That work table looks like it needs more than one vise.🤙🏽awesome YT vid as always Boss Jay🤙🏽
Liked and subbed, great video!
Thank you Jay for the very informative video! Good stuff! I'm used to using plastic gauge to measure bearing clearance. However i understand this method doesn't precisely measure the clearances close enough. I'll definitely be using this method going forward. In your video you mention setting the Outisde Micrometer to the Main bore housing diameter mid-level. How do i determine or find that number?
When jay talk i listen
Hi I like your show it has helped me understand. I’m into a few motors but lately the old vw air cooled ,I have book manuals off course but wondering on your thoughts for crank and big end clearance, thank your
Thank you Jay for this amazing video, this is exactly what I m looking for!!!
Question though, the bore mic, what’s the brand and pant number boss?
Great video, any recommendations on where to buy the micrometers and bore gauge?
Great video. Similar saying is you will never lose an engine on the loose side but you may on the tight side. I still can't figure out why some BMWs have bearing issues, I know they r tight but something you said about mains being tight may be part of it as even when big ends r increased they still seem to have issues.
Very informative Jake are the best i personally was doing thinks wrongfully now i know 😂❤🙏🇵🇷💪
The knowledge in watching one real street video is like watching three or four average builder videos.
Great video! I found it very informative for a future project.
In the meantime, I'm just doing a stock rebuild (Started as a head gasket replacement).
Since there was no actual damage and I'm only replacing components because I'm already taking the engine apart, are all those measurements necessary and can I just put back in the exact same as I'm taking out?
Jay, you don't put a drop of oil on the main túnel before you install the bearings? Good video 👏🏽👍🏼
Hi, really great videos Jay. If my engine uses torque to yield bolts which are single use. is it acceptable to use the old bolts for all the checking and then install the new bolts for final assembly. many thanks Andy
I was going to build my own block until I saw this video, best to leave it to the pros.
Thank you for your videos Jay.
I always have issues measuring the journals and pistons with micrometer. The readings are never the same for every measurement. Is it that I do not get the center of the journals and center of the pistons. What might be the cause?
Nice video super good information but you didn't stretch the bolts or you just torque them to 45 ft ?? Thanks if you respond
Great vid. Is there a rule of thumb when using 2 different bearings either on the mains or rods which side the thicker bearing goes? For example, u use the thinner main bearing on the block side vs the main cap side? What about the rod bearings… thinner rod bearing goes on the rod cap side vs the rod side?
Good video. Although I'm building a 460 385 series. Don't know if those bearings are available??
This video answered a huge question I had; which is the difference between H and HX bearings!
Now, can I use a split set of oversized bearings and HX bearings? or does a split set only work for STD bearings?
Very true about the bearing manufacturer messing up. I had King send me incorrect bearings and still told me I was wrong after sending then pictures of bearings that weren't even keyed for my engine.
can't belive so few views. grood stuff
What's if it's a torque to yield bolt. Do I need to change the bolt everytime I do a measurement? BMW S63 engine for reference.
Hells Yeah Jay!....
LET'S GO...🏁
13:00.. what oil and oil weight do you recommend running this tolerance?
I use the King Racing bearings... Unfortunately they don't make a coated main bearing for my platform ( Ecotec)...I use aluminum bearings but then again I'm only making 500rwhp power.. they do make coated rod bearings for my car that I use
But I have never had a problem with the aluminum bearings they're actually probably the better choice for a frequently street driven engine
Do you have any recomendations for micrometers for hobbyist starting out on building their first engine?
And forged pistons expand more then cast😊
For install rod bolts, do you prefer using torque wrench or stretch gauge more? Thx
Thanks so much, great video. I am working on a BMW m20 6 cyl. The rod bolts are spec'd to be turned only once. Apparently they stretch when torqued to spec and once stretched they can't be unstretched, so when you tighten rod bolts to check clearance what should you do with this problem. I don't want to buy 2 sets of bolts. Thanks again.
This video should be considered the most CRITICAL part of building an engine correctly. What separates a serious engine builder from a non-serious person who just slaps motors together - MATH.
If you don't wanna' do this yourself for whatever reason, tell the machine shop you're using to clearance the block for you. . . . . .THEN VERIFY THE BLUEPRINT NUMBERS THE MACHINE SHOP GIVES YOU TO ENSURE THEY DID THE JOB YOU ASKED FOR!
no doubt, this is just something you can’t skip over. I wouldn’t get an ounce of sleep assembling an engine without measurements and double checking the clearances.
I seen you changed gauges when you went from measuring the crankshaft to the rod… do you need the sunnen bore gauge or any inside dial bore gauge will work if so do you recommend any brands
Talking about bearing clearances if you make your clearances smaller or bigger is it necessary to change the tipe of oil you are using also or wouldn't the oil have any affect on the bearing clearance
Great video, loved it! Great presentation, easy to follow along and highly educational. Please continue doing these!
There are three things I would like to hear your opinion on:
1. All of clearances were measured cold. Of course we cannot realistically measure at hot operating conditions. If one follows the manufacturers' guidelines, who most likely accounted for the thermal expansion of the different materials and consequently thermal distortion, we should still operate with safe clearances I would assume. Is there any way to account for the thermal distortion during cold assembly that you know of?
2. With respect to the bolts or studs, I see two potential issues. First, there are torque to yield (TTY) bolts which are deformed not just elastically but plastically (permanently) as the material is stretched beyond its yield point. One cannot bolt these down several times unfortunately. I guess these are pretty uncommon in the high performance industry. Do you have any advice about how to deal with TTY fasteners? If one wants to check clearances, one has to use a second set of these fasteners during the build. At that point I would guess going with a higher quality fastener is the also the cheaper option anyway.
3. Is there a specific reason why, when you are bolting down the fasteners, you are not using fastener assembly lubricant? I thought skipping the lubricant can give you erroneous readings, which might be mitigated by re-installing the fastener several times, according to ARP.
Some insightful questions, would love Jay to hear Jay's opinion.
Did you find anything about tty bolts on this topic ?
Can't wait to buy the item on ebay I got on my wishlist from your store.🔥🔥🚀🚀🔥🔥🔥🎯⛽⛽🚨🎯🏁🎯🏁🎯🚨🎯🏁🎯
Hey what brand of mic’s do you use or could you get us a part number also on your 3/8th t handle cause I wanna be like you when I grow up so I might as well start saving up for my tools since now
if anyone has wondered what 24 karat gold in video form looks like, its right here. beast mode
plastigauge - for example... is indicating the entire difference in diameters, correct? so the clearance / 2 is the actual difference in radius. Thoughts? THANKS
