[@RestoreIt]

Thanks for watching! I will reply to your comments once this storm passes Alicante and my internet comes back!

[@RosaSD30]

My boyfriend and I are super fans of your channel!! We are both ingeneers and we appreciate your work so much. Furthermore, we live in Elche (Alicante). Hope we could meet you...✌️

[@GroovyDrifter]

I have friends there, hope all ends soon. Best wishes.

[@Zouguuh]

@Restore It, please make your video's longer man. 15min is too damnn low. Make it at least 40min please. What you doing, is better than any movie at Netflix. Goodluck bro

[@iTeerRex]

Only if I ask question I would appreciate a reply, but to general comments, nah I don't expect any reply. Great series btw.

[@jesusaraujogambarini84]

I’m from alicante cared to translate your videos to Spanish ? I’wouldn’t mind giving a hand

[@masterbeta343]

Am i the only one who thought the ultrasonic cleaner sounded like the start to a sick song

[@mr.skeltal8687]

MasterBeta343 sounded like firestarter for the first half second

[@Canon7D365Project]

haha i thought so too

[@osmontpaul2493]

as in The War of Worlds ! :)

[@Tiagotaf]

The satisfaction of seeing a motor being renewed like this is too much!! I bet you loved every second of it. Thanks a lot for sharing with us!

[@bavarium313]

The best series on KZbin by far, keep the insanely hard work up mate, I can only wish to put the same love into my little Mk2 Fiesta! 👌

[@RestoreIt]

Thanks Bavarium! Appreciate it!

[@franciscodieguez5187]

If you liked this, I recommend you 100% Cameron Niemela's CR250 build

[@keremardicli4013]

The definition of quality, as always.... perfect job. Do not get bothered with the people who are complaining about the rectification process. This is not a walkthrough video.

[@motheolebelo]

How privilege i feel to have watched such an in depth process of a Cylinder head and Block clean, testing and re-assemble. Thank you for bring us such content, we truly appreciate it. Thumbs up to Rectidama for allowing you to film this content.

[@Chris_8270]

This restoration is an absolute credit to you sir, when this is finished its going to be the closest thing to a brand new E30 you'll probably find

[@2003garyb]

How in the world did man devise such a precise piece of technology to power our cars??? Awesome to watch! Thanks Steve. I know you must be getting pretty excited. We are too!

[@jimmyindahouse]

I was thinking about this project of yours just before entered my home notification popped up. cleaned my home, showered, made tea and now I will enjoy this video. Thankyou

Would love to see you taking the car to a Dyno when finished

[@ShiroArctic]

Watching a machine shop do their thing is immensely satisfying to me.

[@avec-zam7301]

Wow, i want to all this on a Honda cb 750four a year or two ago and i'm realy feeling the same joy watching your video's. Every job done, every bolt tighten is a step closer to the final Key turn. I wish you a lot of succes and joy when this is all over. Greatings from Belgium.

[@Theresistance64]

M30 "Big Six". Iron block, one of the most bullet proof engines ever produced by BMW. Had one in my 92 735iL.

[@LifeRunner4000]

Are my eyes deceiving me, or did he not use any assembly lube when assembling the bottom end there?

[@creative.with.JeffHak]

nope i think they did not use any .

[@juniwalk]

@@creative.with.JeffHak they must have it was just not on the video. it would not rotate so smoothly if it was not lubed.

[@TheJond007]

I was wondering the same but looks like they did. Bearing surfaces are shining.

[@JettaMK]

You can see the red fluid on the bearings.

[@M1LAD81]

Yup you're right. No assembly lube which is distrubing and even more so disturbing when the engine gets cranked for the first time. Yikes!

[@orlando1a1]

After this superb restoration, this car is surely going to run like a dream - better than the original.

[@lsswappedcessna]

This is going to be the most reliable BMW in existence.

[@leighharron]

Fantastic work. Leave all the parts there, makes you look all cool with an art installation in your house

[@ichewtoast111]

That ultrasonic cleaner is awesome.

[@denchikcrazy1064]

Very nice my friend!!!! Russia is watching.Good job

[@enriccrespo624]

Ostias con lo bien que hablas inglés no sabía que eras español jajaja. Me encanta tu canal tus videos me tienen enganchadisimo me miro cada segundo. Sigue así felicidades.

[@mada0zani]

Hi My Friday wouldn't be completed without an episode of restore it

[@DonchoMazhlekov]

I love how most of the comments are "oh no lube on the bearings" or "oh no they didnt do that thing"! Relax, people, these are professionals, quite good ones, too. The probability that they've done that more than you have and better than you have is quite high. There is lube. They have done everything correctly. Bear in mind that this is the 'short' version, you can't (and don't have to) film everything. Otherwise - great job on the engine. Looks good now.

[@AkAsCoTTii3]

Jesus, the sound that ultrasonic Bath makes! Almost spooky

[@numanocel5073]

Don’t wanna wait till next week! Great job!

[@kieranmann9761]

Excellent, you are lucky to have a great machine shop like that.

[@howardtakavingofa5270]

Good work for us bmw enthusiasts

[@Stuntman707]

That’s awesome, now you can start the fun bit. Figuring out how it all goes back together!

[@cvaz7623]

when taking off the springs for the valves. An easy way to get them off is a good smack with a socket and hammer

[@electronic7979]

Good restoration 👍

[@am_jeds]

That engineering is absolutely gorgeous!

[@uvasam13]

I'd check the valve lash after the head is installed and torqued down. Even with both mating surfaces decked, the head twists and moves around a little after the bolts are in and the valve clearances change. I set my valve lash after I rebuild my 885 and before I torqued it down. After I put the headbolts in, all of the clearances were too tight and I had to readjust. Last thing you want is to wipe a cam or wear out a rocker on break in. Good luck.

[@ViktorLab]

Как же круто наблюдать за восстановлением джвижка!

[@leolammas7940]

well meaning tip:Double check each valve clearance after tightening the eccentric because the tightening process can[and did on me] rotate the eccentric or leave the feeler gauge in place until tightening is complete ant the drag of the gauge stays the same. I enjoy watching your 'no nonsence' instructive viodeos.

[@SmasherFPV23]

Hello! I'm watching Your channel from a along time, and thank You for the detailed videos. As a bmw fan and owner I suggest checking valve clearance AFTER assembling the head on the block and torque-ing it down.

[@bostedtap8399]

Excellent company, very thorough and with the correct equipment. Thanks for sharing.

[@zachogdahl210]

I would absolutely love to have one of those ultrasonic cleaners.

[@Coyote27981]

It is preferred to use the socket side of the extension to push out the rocker bars. You can damage the aluminium plugs at the ends (dont ask me how i know...) If you hit it with the square end.

[@sonyhk3824]

Nice and good luck, looking forward next week

[@bg73]

The torque wrench is such a clever tool

[@maddogmiddelburg1963]

Strange way of working first installing the pistons and then cleaning out the holes with a tap.

[@othmanreparaturen4151]

😔

[@StephenJohnson-jb7xe]

I am looking forward to seeing the next video. Seeing as you painted so many parts with silver paint I was surprised to see you went with black for the block. If you really want an ultrasonic cleaner there are vids on YT showing how to DIY but I guess it depends if you have enough need to justify the space it takes.

[@valerioemidio]

The saddest part is when it ends... Waiting for the next episode!

[@1leggeddog]

awesome to see the full process

[@thesneak281]

Did you reuse the Pistons? No stroker build or anything just a refresh of the rings and bearings? I'm looking to do the same thing. Refresh a bottom end and hopefully not have to bore it bigger.

[@UA_VITAL]

Nice Restoration !!! Good work

[@lanimereala]

i swear on everything i own that your E30 Touring restoration and Mastermilo's T55 tank restoration are the only two series i really look forward to on KZbin. Couldn't have clicked faster.

[@magnum357225]

I prefer the milling machine cleanup of the block and the head much more than the gringing wheel, because u never know how the grinding wheel is spent,and when was it checked last time. Just a sugestion

This video made me happy. Thank you!

[@Godofhorrorsend]

[@Proth1975]

Interesting difference in machines vs US.... The grinding stone vs a decking/flycutter head is a really big one.

[@victorpelini5995]

What do you mean ? Whats best, grinding stone or decking machine ?

[@md4luckycharms]

@@victorpelini5995 flycutters can remove a lot more material faster, but they might not have the best surface finish, ideally you'd deck it and then use a surface grinder to get the best results but most of the time a flycutter will do the job good enough and cheaper and quicker

[@victorpelini5995]

@@md4luckycharms hoooo I see Well, ive seen more grindstone than flycutter in machine shops here (France) so I guess its cultural 🤷 Also you should remember the fact that murican motors are bigger and usually have twice the cylinder count 🙃 (dem V8)

[@md4luckycharms]

@@victorpelini5995 It's interesting to see the differences in engineering culture between countries I must say, thinking about it, it might be nice to see those differences mentioned at engineering schools. However, as to the reason I see more flycutters here in the States than in France. My thoughts are that much of the machinery was concentrated in the remaining machine shops after the world wars while here in the US the wartime machines got sold to the general public. Good quality used milling machines are in abundance here while I don't see many surface grinders out and about. I figure that the shops over there that could do that kind of work had the equipment already or got sufficient business that they could afford it, whereas here you had options as to which shop you could go to for cheaper. Not to mention that tolerances for engines are probably a bit more relaxed over here. Just my thoughts with the information that I currently have. On my bucket list is traveling to Europe to figure out how we got from blacksmithing to lathes to Mills to cnc machines repeatedly accurate to the millionth.

[@victorpelini5995]

@@md4luckycharms i have to agree, also machine shop arent that common here, you kinda have to do some miles before finding a place to do it

La verdad que no estoy seguro, pero voy a suponer que sos de España. Podrías hacer un vídeo (tipo blog, algo sencillo) explicando la historia de este auto, de donde salio, que te motivo a restaurarlo, porque termino en las condiciones que estaba antes de que empieces el proyecto, etc. Incluso en español que supongo que es tu lengua natal. Conocemos cada rincón de este coche pero nada de su historia. desde esta tapa que esta restauración esta genial, ya quiero ver ese motor en marcha. Saludos!

I am probably not first not even second and definitely not third that’s all that matters! And “I AM HEARTBROKEN😭”

[@_i-kr6eg]

Great to see a m20 coming back to life, great work. Question why did the engine guy not use lube on the bearings! mate you'll spin a bearing on start up I'd be taking the main cap off and adding lube asap

[@guillebenitosanjose]

Te sigo desde hace tiempo, me encantan tus videos. Molaría ver alguna colaboración con algún canal español ya que estas aquí, un saludo desde Madrid!

[@TrancerGTR]

Full engine spa:)), and another great video...

[@robbalinski1606]

Really hoped they lubed the bearings before turning the crank...and checked for oil clearence on the bearings

[@mxrider2strokebraaap54]

Really nice work😍

[@paulzapodeanu9407]

Those holes drilled into the counterweight on the crankshaft, are they for precise balancing? Went to the Porsche museum recently and saw a lot of these, for example on a 917k crankshaft. On the other hand at the Mercedes museum I saw a crankshaft from a 1930 racing car, I think a W25, and that didn't have them. I thought it was very odd maybe they shaved them of in a less conspicuous manner.

[@dpratt776]

I'm assuming they checked the clearences before resembely the crank, main journals and connectings rods, and no visible sign of assembly lube on the new bearings? And the new rings, did they gap checked and correctly clock to each coresponding piston or are these items not relevant for a modern (ish) engine? Great build video.

[@krlichos]

Dont u understand that EVERITHING that they have done its not in the video? Do you think that a rectification shop like that, will not prelube parts that need to be lubed? A lot of engineers knows it all around here man...

[@alhafizwacth6661]

I always wait for this episode 🤙

[@videocruncher]

Looks like they've honed cylinders without boring them out first (also used old pistons). Not a complete overhaul considering that cylinders wear out unevenly.

[@KrisisVal]

8:03 "literally perfectly flat" you felt that just with your hand? damn.

[@johnymerano3692]

Bearing shells without any lube, taping holes after pistons are in place and no check on piston rings? Could be a slight problem from my POV. The engine will be still way better than before though

[@fw1421]

What? New bearings and they install the crank DRY!🙀🙀🙀🙀🙀

[@SupermasiveHole]
