this is why this chanel has made it this far and has more to come. they have an idea, take action, face defeat, get back up, take a new angle, try again and follow through, making enjoyable and educational content along the way. this team is amazing so glad yall do what you do.

[@mad_like_a_hatter5469]

Unfortunately they went all in on the wild card if they did 1 or 2 episodic videos like history or science so we all could look forward to the next one instead of sifting through niche stuff. Love donut and have since the start but finding it harder to spend time on these videos with shots in the dark.

[@PneumaticFrog]

I wish donut made a far longer video of this rebuild.

[@MrPrajitura]

IKR? like, they put in the work, why not actually show more of it? my guess is they're thinking shorter videos for higher retention.

[@HaiFisch_TV]

I agree, this could've been a 45mins video and we all would've really enjoyed it

[@MrSatchelpack]

They could totally have a separate channel detailing the work for all the wrench heads who want to do something similar. It's almost the same footage right?

[@PneumaticFrog]

@jbphilly1234 not necessarily. They could mark it as educational. Educational videos usually get a higher pay per view. Or post it on a second channel I would happily modify a car on camera for donut.

[@PneumaticFrog]

@@MrSatchelpack yes exactly what I was thinking

[@SvdSinner]

Episode idea: Do an engine rebuild with only cheap weekend warrior tools and show where good tools would have made things better.

[@xilogex7403]

I love to think that entire episode would be just them losing socket bits every time they try and it’s hilarious

[@SonicProvocateur]

They only get use the Walmart $30 special tool kit. 😂

[@SvdSinner]

@SonicProvocateur Many years ago, when I was young and hungry, I pulled off a lot of fixes with little else beyond a cheap socket set and a few crescent wrenches. Never underestimate the guy with more determination and time than money.

[@Fopenplop]

Yall are paying for tools??

[@LostMyName15]

Yeah, not that impressive if you have hands and not meat sticks to work with... basically rebuilt my 5.9 Magnum with a 50$ ratchet kit, a BFH and a 3' helper bar... It's getting torn down today since the truck gets lifted/SAS/4-linked with an exo cage. That's 4 years and 28000 on here and other than the infamous plenum leak it all looks perfect still.

As a student in school for diesel tech, I actually had to do this with an international D466 we did have the torque specs and the specs for the valve lash, but that's the only things we used the manual for. It took my group about 11 weeks to get our engine apart, put back together, and have it run. It was a cool process and I recommend it for anyone who has the time and money and wants to learn all the ins and outs of an engine

[@tommyellis7728]

11 weeks? It took mine 4 weeks to rebuild a: 6.4 Powerstroke, MX13, DD15, ISX Cummins, and a 400 Big Cam Cummins. We were there for four hours a day. What the actual fuck took y'all so long on a nearly fully mechanical 30-50 year old engine?

[@kanojo1969]

Bolt torques are really important for a good long-lasting engine. But I stripped and rebuilt my corolla's 1971 engine when I was 16 without even knowing what a torque wrench was for. And it ran for almost a year, until I blew a piston and decided to buy a crate replacement. Just to get an engine started and run for a while you can forget about torque, as long as the bolts aren't actually loose and the head is properly tight on the gasket, it will start and run just fine.

D series, d16 was the first engine I ever rebuilt, it's so simple and taught me all the basics I loved it, good times

[@mas13ish1]

Nice job! It sounded pretty weird to me, but I'm guessing that is because it had not exhaust on it. I wouldn't have a clue on any of those torque specs, so you guy are killing it.

[@superrad1659]

well, its a Honda w/no exhaust, so naturally it's tone will be that of audible dookie lol. But you can listen to the firing of the engine... once its going it has a pretty steady pulse to it. If the timing was off it would have a rougher, more unbalanced purr to it.

[@CormacHolland]

Yeah it’ll definitely sound weird without the exhaust, and microphones are not great at picking up how the actual engine sounds.

[@nickgir]

Every Honda I've heard without exhaust sound like a bubble machine

[@superrad1659]

@@nickgir exactly my point lol. I used to work w/a cat that had 4g Prelude, open headers... One of the most obnoxious cars ever lol. We were doin pulls after work 1 night, "play" racing lol, and passed a cop... He (Prelude) was in the opposite lane n got behind me (cuz my TT was faster 😁), cop pulled him over, I kept going... Cop accused him of "streetracing", Coworker said he was only trying to pass "somebody" going under the speedlimit, and that it only SOUNDED like his car was going fast 😂 I dont remember if he got out of it or not, I wanna say he just got a speeding ticket.

Reusing old engine bolts (and then overtorquing them) seems like a great way to cause catastrophic engine failure at some random time in the furure.

[@stereotypicalwhitemale848]

Shouldn’t be an issue as long as the threads are in good shape you can tell if a bolt was stretched.

[@anonomus460]

[@DamdamF]

[@BrendenPragasam]

Instead of being some sort of "challenge" episode, i honestly wish they took the opportunity to make this a money pit episode and showed strategies you could use when reassembling something without instructions. If you're working on a make of car thats not that well documented its extremely common to do things without any instructions of any form

[@misseselise3864]

what you should do is not assemble something without instructions. they don’t plan on using the engine for anything so they wouldn’t be losing anything if they fucked it up

[@BrendenPragasam]

@@misseselise3864 I've assembled an engine with instructions from a similar family of vehicle, which is definitely a strategy, just taking note of changes ( very common with Volkswagens that engine share)

[@TheRealSykx]

@@misseselise3864 the last 30 seconds beg to differ

[@BrendenPragasam]

@@TheRealSykx its a 12 minute video the last 30 seconds aren't that enticing for watching all of it

[@nunyabusiness896]

IMO the takeaway is that torque specs aren't as critical as people think. Most of torque specs is to ensure bolts aren't literally jiggling loose nor so tight they snap off. Torque specs are literally just tested values that worked during the R&D phase and they have techs use to ensure failures weren't due to faulty assembly. Someone that has put enough things together to know the feel of a well tightened bolt could probably successfully rebuild an engine without even a torque wrench and have it run just fine. In fact, people will do that all the time during a rush repair right before a race when they don't have time to setup torque wrenches and look up specs.

[@Harbara]

We need more of this

[@poluzka2724]

[@packerman1203]

I'm not a honda expert on anything besides my own but doing rod bearings on my J35z2 taught me a few things. Right away the lack of an angle torque spec was a little worrying, cause the rod caps for my engine was 35ftlbs and then 90 degrees. Head bolts were worse, that I believe was a two step lbft sequence of like 45 and then 80 and after that it was 3 rounds of 90 degrees in the sequence, I was very tired after that and I was just changing out cylinder 6's piston with cylinder 3 from my first engine. (After doing rod bearings my engine went on to run another 20 minutes, I blame myself for not using assembly lube on literally anything even though I bought a tube of it. I have since swapped a third j35z2, this one being out of a 2014 RDX, into my crosstour, got about 1800 miles on it so far)

[@aaronburratwood.6957]

I rebuilt my EJ25 having never did this myself before. I also port/polished the heads and added headstuds. I too afraid the pull the pin on the timing tensioner though.
