Episode Notes

Our small block engine rebuild series continues! With the teardown and machine shop episodes out of the way, we can now start rebuilding our block. In this episode Chris shows you how to rebuild the bottom end of our block using pistons from MAHLE Motorsports, and a crank from Eagle Specialty Products.

This episode features Olivia Korte as our Motorz Girl and also has our regular segments, Partz and Letterz. In “Partz”, Chris talks about dead blow hammers from Craftsman, XS Power batteries, Holley M/T polished aluminum valve covers.and Dupli-Color engine enamel paint.

As always, be sure to stick around to watch our out-takes at the very end!

    YYYYYEEEEEESSSSS!!!!!!!!! New video thanks Guys!!!!!!

  2. b3astieboi2 Says:

    More building less adds

  3. kohnal Says:

    Bout time lol. Hope you guys upload more videos soon. I love watching them. I’ve learned alot from your videos

  4. motorztv Says:

    @b3astieboi2 Well, the ads keep the show going. Without them, there won’t be any more videos here.

  5. motorztv Says:

    @kohnal Thanks! The next episode won’t take as long to appear :)

  6. FordM4Life Says:

    Was there enough clearance for the Crank? i think i didn’t saw you filing the block for it = ) did it fit that good?

  7. motorztv Says:

    @FordM4Life Yes, the machine shop took care of that for us!

  8. foxdmulder Says:

    I want to do some work on Olivia’s bottom end :D

  9. Gasser4x4 Says:

    0:02

  10. kohnal Says:

    @motorztv Thanks guys. And as a ingestion for a new series. Maybe some body work showing some dolly methods or maybe how to mud and the different types of mud

  11. Terreos Says:

    Wow wow wow! Did you say you’re going to be restoring an older Mustang?! I can’t wait for that! Any chance you’d be willing to say what year it is?

  12. motorztv Says:

    @Terreos I did! It’s an 87 GT 5.0

  13. Terreos Says:

    @motorztv Fantastic year choice. I was born that year.

  14. motorztv Says:

    @Terreos What year Mustang were you hoping we’d restore?

  15. Terreos Says:

    @motorztv A 1964 mustang would’ve been really cool. I’ve only seen one in person and seeing one restored would’ve been just too awesome. Though as I said I like the choice of the 1987 also.

  16. motorztv Says:

    @Terreos A 60′s Mustang would be fun… we’ll start with the ’87 and go from there :)

  17. Terreos Says:

    @motorztv I’ll be anxiously awaiting the first video.

  18. ilovecats748 Says:

    I can’t wait ’till the Mustang restoration episodes!

  19. nightpwner Says:

    I can’t speak for engine enamel Duplicolor, but I can speak for the regular paint (especially bumper paint) Duplicolor and I say it’s garbage. Chips easily and the clear coats aren’t any better. There is nothing wrong with my paint prepping skills, I pride myself on it actually. And with that-I’ve heard good things about Rustoleum. Be cautious of Duplicolor is what I’m getting at. Good episode. Interesting stuff.

  20. achuck4321 Says:

    I love this show

  21. dc5000123 Says:

    5:31 reminds me of when I sing in the shower haha !!!

  22. motorztv Says:

    @achuck4321 Thank you for watching! We have more on the way!

  23. albduke1 Says:

    do you plastigage the journals

  24. BlitZzDesigns Says:

    Not too keen on all the advertisement, but good video.

  25. Hustle095 Says:

    @nightpwner A friend of mine had me paint his ’98 Malibu Rustoleum Flat Black out of a spray can. It took a good 15 cans. But it turned out really good for spray paint. Now here’s the kicker: he lives in Iowa. Bad winters, sometimes bad summers. And we never put a clear coat on it. The paint was put on three years ago. Still looks the same as when it went on. So yeah, I’d say Rustoleum is good, lol.

  26. TheAnonymousFilm Says:

    I will never be able to learn anything from these videos id you put girls like this in them…….

  27. TheGetawayer Says:

    Really nice episode, Chris ! I love american V8s and seeing work done on them is really great to watch. Can’t wait to hear it running ! Are you going to Dyno it ? Engines and Motorz-Girl eye-candy, love it. Greetings from germany, Guido aka TheGetawayer

  28. motorztv Says:

    @TheAnonymousFilm LOL

  29. motorztv Says:

    @BlitZzDesigns Thanks. The ads pay for the good videos :)

  30. motorztv Says:

    @TheGetawayer Yes, we are going to dyno it in an upcoming episode! Thanks for watching, Guido! Keep up the good work at your end of the world!

  31. chris Says:

    FINALLY A NEW VIDEO

  32. Westcoast802 Says:

    Great video, very interesting to see how the engine gets recovered. No channel on YT which is compareable with yours, keep on with this great work!!!!

  33. T4JZtv Says:

    Wow Great Job I was waiting for this episode for long time I got so bored waiting that I subscribed to your channel so worth it. Keep it up.

  34. 35057 Says:

    LOVE engine internals!

  35. miguelzepeda20 Says:

    Good video … is it hard to turn a 350 in to a 3(?) Stroker

  36. 67mustangreg Says:

    why would you only do a small patch of strip then paint? and wire wheel takes a lot of time and skill to get right… I preffer chemical strippers. they do a picture perfect job and reach all the nooks and cranies.

  37. motorztv Says:

    @albduke1 No, but we used micrometers to check the tolerances.

  38. motorztv Says:

    @miguelzepeda20 We forgot to mention it’s a 383, and no–it’s not that hard. Thanks for watching!

  39. motorztv Says:

    @35057 Thanks! We do too!

  40. motorztv Says:

    @T4JZtv Thanks for hanging in there!

  41. motorztv Says:

    @Westcoast802 Wow… we’re speechless. Thanks for subscribing!

  42. xavier3961 Says:

    Can you put the cam in before the crank or is it best to do the crank first? sorry if I am getting ahead of the episodes.

  43. motorztv Says:

    @xavier3961 As far as we know, it shouldn’t make a difference.

  44. albduke1 Says:

    can you give a breakdown of all the machining done to this engine and all the tricks that you did on the description

  45. motorztv Says:

    @albduke1 Sure, but you can check the motorz(dot)tv website, or this channel for the machine shop episode

  46. PattyManZ28 Says:

    @motorztv Could you maybe label the videos on this build in order on the channel? Thanks!

  47. Masterofdisaster151 Says:

    After scrubbing the loose paint off the block is there any other prep-work required, like applying primer, before you apply the duplicolor paint? Or can it be sprayed directly to the block and over the old paint?

  48. 89Carfreak Says:

    @xavier3961 Put in the crank and pistons first. You want to be sure to focus on one area at a time to get the best result.

  49. Karl21836 Says:

    haha love the sound effect in the PARTZ section :D

  50. motorztv Says:

    @Karl21836 Boioioioioioinggggggg!

  51. motorztv Says:

    @Masterofdisaster151 We sprayed it directly on the block, after cleaning the surface with a good degreaser.

  52. LYinKansas Says:

    so much blush lol what a doll!

  53. bedbugg1 Says:

    The next motor rebuild video! you have no idea how many times I rechecked the Motorz youtube seeing if the video has been posted!

  54. Lehtosenkanava Says:

    when are you going to upload next episode? Why are these episodes uploaded in such slow pace? :(

  55. motorztv Says:

    @Lehtosenkanava The next episode will be out within 2-3 weeks. Thanks for watching!

  56. brandon1997bmx Says:

    when will you rebuild the top end ??

  57. motorztv Says:

    @brandon1997bmx Next episode… coming soon :)

  58. beefystik Says:

    For some reason, this episode seems much hotter. I mean better…

  63. motorztv Says:

    @casselamericanista We’re planning on publishing it 3/23.

  64. nat1243 Says:

    when doing ring gap shouldent you use the piston to put the ring in the cylinder to get it in the cylinder evenly?

  65. impalassv Says:

    As far as you know, will you guys be doing anything with an LT1 anytime in the future? Or is there an episode that one was done already? Thanks

  66. motorztv Says:

    @impalassv We haven’t done anything, but that’s not to say it won’t happen!

  67. briansmobile1 Says:

    I LOVE the Dupli-Color Engine Enamel you featured at 17:11 ! I’ve used it for years. I use the gloss black ceramic engine paint all the time for wiper arms and wheel wells too. It holds up to the heat of the sun and brake heat too. AWESOME PAINT! I just wish AutoZone still carried it.

    YouTube does that sometimes, but the video is fine. Just click to another section of video when that happens, then click back.

  72. NemesisSypheroth Says:

    Who’s the new chick? She looks hot.

  73. motorztv Says:

    Olivia Korte (Motorz Girl) joined the cast with S05E02 (Machine Shop episode). You can see more at motorzgirl(dot)com or her Motorz Girl Facebook page.

  74. mav93angel93 Says:

    That girl is sexy and good explaining on the rebuild

  75. NemesisSypheroth Says:

    Thanks. You got yourself a keeper!! ;)

  76. motorztv Says:

    Thanks… we all agree with you!

  77. supersanchez1991 Says:

    she is hot

  78. Michiganborn1969 Says:

    Great video as always Chris. I also would love a video on window tinting. We have an old ’96 Accord I easily removed the old cracjed & bubbled tint with a steam machine, a razor & a few towels. As how to put clean, streak & bubble free tint back on would be an invaluable video especially under the hot California summer sun.

  79. GenuineCriminal Says:

    Nice looking chick does help the show.

  80. 333krisb Says:

    I love this show so much its helping me learn so much I am in the military and I am getting out to be a mechanical engineering because of your show so thank you so much

  81. motorztv Says:

    We’re glad it helps! Thanks for watching!

  82. TheBaller97 Says:

    i love the show and im a highschool freshman and i was wondering when i got get to college what should i major in to get into cars i was thinking mechanical engineering but im not exactly sure

  84. DingDangg Says:

    Is there a trick to putting the piston rings onto the piston without bending or damaging them?Also, how much does a rebuild kit cost such as the one you’re using in this video? (everything)BTW this is the best video i’ve seen yet for SB rebuilds.

  85. austinrockshard Says:

    I’ll rebuild her bottom end ;)

  86. IMKINDOFABIGDEAL13 Says:

    just a tip for next time. before you send your engine to the machine shop that is the best time to remove the old paint this way you can get ALL of it off. then once you get it back you can use a good primer before you paint it. its just better to start completely fresh as opposed to removing just the loose paint

  87. stiffed69 Says:

    i have now.. become…extremely jealous of your job haha, she is a beautiful looking girl!

  88. EndIessIy Says:

    Subbed because thats one gorgeous girl.

  89. dawg1157 Says:

    Don’t you have to use Plastigauge to measure the bearings and such?

  90. TheJaky1515 Says:

    I have rebuilt 100s of small blocks over 30 years never a failure. It doesn’t matter witch dam wat the piston rod faces. I can tear down clean rebuild and paint last thing in less that 2 hours.your slow

  103. StickToMyRawr Says:

    Any book store, maybe an auto parts store. I’ve bought a few books like that one from books a million

  104. jthuggamk3 Says:

    Thanks for the reply I ended up buying one from napa.

  106. OlympusHeavyCavalry Says:

  107. OlympusHeavyCavalry Says:

    I thought a piston pin was called a gudgeon pin?

  108. byankees12 Says:

    To make it easier to follow the progression of these videos, you should number them in the title. Also, when you add a new video in the series you could go back and post a link that would direct us to the next video. Great videos and very professional.Thanks

  109. oSHOLLIVERo Says:

    What do freeze plugs do ?

  110. chevyman5436 Says:

    They’re there for when some jackass puts water in the radiator during the winter, water expands when it freezes which would crack the block, so instead when the water freezes, they pop out the freeze plugs instead, sparing your engine. Lesson here? Don’t put straight water in the radiator in the winter!

  111. chevyman5436 Says:

    Don’t you need to plasti gauge the bearings to check the bearing clearance?

  112. oSHOLLIVERo Says:

    Hmm. I didnt know that. So when the water freezes they just pop out ? Makes since. Thanks man.

  113. chevyman5436 Says:

    @oSHOLLIVERo Yep. Another thing about them is the MAIN reason the holes are there are actually so when the block is casted, they can get the sand out. So they figured instead of welding the holes shut, they’d put plugs in case it freezes

  114. MrCobraterminator Says:

    How much would the entire top and bottom end rebuild cost?

  115. mattg716 Says:

    So, from start to finish, how much did this whole process cost, approximately? i am curious because i would like to this to my 5.0, doing all the work myself (except machining the parts), but i have no idea of how much it run.

  116. Canadianhuh Says:

    Don’t let the new girls head swell up too much! lol

    he didnt check crank bearing clearances

  121. Yayforhappy1 Says:

    I am rebuilding an engine, only problem is my “shop” is on the second floor, could you give some advice for hand carrying the engine?

  122. Whatthefuckisgoingon Says:

    its a good video i just feel u rushed thru the critical parts such ass the piston rings and others and used up valuable time for advertising…..

  123. Andrew Schreefer Says:

    why would you not use plasti gauge to check the bearing clearances on the main caps? And you torque the 4 inner caps first and then hit the first main cap with a rubber mallet or hammer on another hammer to seat the thrust bearing

  124. bigmike616 Says:

    how the hell did you have a hard time finding parts for a jeep cj….you can pretty much build a whole jeep from a quadratec catalog

    @ 10:59 that bearing DOES NOT go on that rod end cap. Also to check crankshaft end play you need to use a dial gauge W/ magnetic base and two pry bars. And that’s just for starters on what’s going on WRONG HERE. ~V~ Obsession

  163. Robonza Says:

    I noticed that. They didn’t do the most important thing either. Check the bearing clearance with plastic gauge. The ad also said the pistons experience many explosions per minute. That’s only if you get detonation. Fuel burns in the chamber. Hot chick tho.
