In this episode, I finally show you the work that's been carried out at Rectidama. A great engine machine shop close to me. rectidama.es. Firstly the head is completely dismantled. It's then ultrasonically cleaned in preparation for a pressure test, which it thankfully passed. The block was then skimmed and it's cylinders polished. All of the parts that needed to be put back in were also ultrasonically cleaned. A small repair on the head was necessary as the coolant, and probably water mix had eroded away some of the coolant channel. The head was then skimmed again and the new rocker arms, valves, springs, eccentrics, seals, bearings and the rest of it was put, in the same way, they came out. The new piston rings were then fitted to the clean pistons, ready to go in after the new bearing shells and crankshaft were also fitted. The pistons and connecting rods were then attached and tightened down to the correct specification. Finally, the valves were adjusted to 0.25 to complete the job.
Visit rectidama.es for any and all engine work you need in Spain. They serve all of Spain.
I cannot wait to get this engine going for the first time. However, the engine I will be putting back into the touring will be the coupe's old engine. Overhauled a while ago, but in good condition. This engine will have to wait for the coupe to be pretty much finished before it goes in.

Thanks for watching! I will reply to your comments once this storm passes Alicante and my internet comes back!
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...✌️
I have friends there, hope all ends soon. Best wishes.
@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
Only if I ask question I would appreciate a reply, but to general comments, nah I don't expect any reply. Great series btw.
I’m from alicante cared to translate your videos to Spanish ?
I’wouldn’t mind giving a hand
Am i the only one who thought the ultrasonic cleaner sounded like the start to a sick song
MasterBeta343 sounded like firestarter for the first half second
haha i thought so too
as in The War of Worlds ! :)
Would love to see you taking the car to a Dyno when finished
The best series on TH-cam by far, keep the insanely hard work up mate, I can only wish to put the same love into my little Mk2 Fiesta! 👌
Thanks Bavarium! Appreciate it!
If you liked this, I recommend you 100% Cameron Niemela's CR250 build
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!
Are my eyes deceiving me, or did he not use any assembly lube when assembling the bottom end there?
nope i think they did not use any .
@@creative.with.JeffHak they must have it was just not on the video. it would not rotate so smoothly if it was not lubed.
I was wondering the same but looks like they did. Bearing surfaces are shining.
You can see the red fluid on the bearings.
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!
Nice and good luck, looking forward next week
Fantastic attention to detail, these guys are bloody good at what they do!
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.
Excellent company, very thorough and with the correct equipment.
Thanks for sharing.
Nice, that’s some real wholesome engine work! 😊👍🏻
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
I love your videos, It’s the only series of videos I am actively watching on TH-cam!
That engineering is absolutely gorgeous!
Good work for us bmw enthusiasts
awesome! cant wait for the next vid!
That’s awesome, now you can start the fun bit. Figuring out how it all goes back together!
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!
Excellent, you are lucky to have a great machine shop like that.
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.
This video made me happy. Thank you!
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.
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
I always wait for this episode 🤙
Don’t wanna wait till next week! Great job!
I love this channel! Keep up the good work sir!
Fantastic work.
Leave all the parts there, makes you look all cool with an art installation in your house
This helps me learn more about engine's
M30 "Big Six". Iron block, one of the most bullet proof engines ever produced by BMW. Had one in my 92 735iL.
Hi bro 👋👋👋 excellent work and engine restoration 👍👍👍
Great work! Waiting for another week for the next one is a bit hard, but I'll manage!
Very nice my friend!!!! Russia is watching.Good job
Good job ! Can't wait to see your next video
awesome to see the full process
Big job, looking great!!
Epic job!!!!
Greets from Greece!,
Strange way of working first installing the pistons and then cleaning out the holes with a tap.
😔
Watching a machine shop do their thing is immensely satisfying to me.
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...✌️
Nice Restoration !!! Good work
Gracias por enseñarnos la restauración y estos procesos. Me encanta. Muchas gracias por tu canal.
Jesus, the sound that ultrasonic Bath makes! Almost spooky
This is going to be the most reliable BMW in existence.
After this superb restoration, this car is surely going to run like a dream - better than the original.
Damn bro so cool cant wait on next episode
Perfect video!!!
Full engine spa:)), and another great video...
Good restoration 👍
Hi
My Friday wouldn't be completed without an episode of restore it
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.
Man i love your videos, i'm happy for you, really. I would like to do the same for my E34 525i m20b25, and you know what ? My clutch died this morning lol... see you next week.🤙
Really nice work😍
Good looking house!
Great video, as always :)
Super cool!
No more to say then: love it :)
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.
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.
Amazing 😍
best channel. FC from Thailand.
I would absolutely love to have one of those ultrasonic cleaners.
Beautifull work😍
fantastic!
They do excellent work, Crack on...
when taking off the springs for the valves. An easy way to get them off is a good smack with a socket and hammer
That ultrasonic cleaner is awesome.
Looking good
Как же круто наблюдать за восстановлением джвижка!
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.
Gran trabajo, ya queda menos para disfrutar ese coche "nuevo"
omg, the wait is horrible! I cannot wait to see the next one!
Wow, what a video.
I wish I had that spring compressor when I did my two M20 heads!
Pierwszy start i panewki wału przytarte. Kto składa na sucho? Brawo
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.
Really interesting video ...
凄いね！これぞプロの仕事！
I love your project restoration from france
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.
I ❤️ IT !
8:03 "literally perfectly flat"
you felt that just with your hand? damn.
love your video. showed the installation of piston #3 twice. lol editing!
Damn life! Haha
Love it
Awesome :)
Seat ibiza glx... una maquina
Yo tuve uno para hacer tramos en pistas de tierra... impresionante...
4:44 the forbidden deep fryer
Yeeeey ❤. Wieeee =) just went on youtube and saw this =) ❤🥰
Cant wait
The saddest part is when it ends... Waiting for the next episode!
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
Firstly, this was a magnificent video, and I love the project.
Question; Did I see rust on the new block sitting at home?
Молодцы парни!
really enjoyed the precision of this episode for some idiosyncratic reason
The torque wrench is such a clever tool
HELL YEAH NEW EPISODE
13:02 satisfying
Am waiting your next Video ✌
OK I'll keep waiting
Another great video, and I see you have a new cat in your house
Awesome
