The crystals are dried up residues from the coolant mixing with aluminium oxide. When not dried up, its actually a kind of goo clogging up the hoses and thermostat
@@RestoreIt actually, that bushing is split, and you can kinda push it out from the middle to both sides, so you can access that bolt underneath. i remember scratching my head like you did trying to figure it out, and when i moved the block around, one half of the bushing just fell out.
14:41 - Removing the thermostat pipe - that happens when you mix two coolants that don't go with each other. they are lists what coolants you can mix and not.
Really nice. This helps a lot to understand the components of the engine and how to do the tear down. Can’t wait for the 2nd episode to see the fresh and newly cleaned engine being built up again.
Those crystals (and similar) are often caused by stuff like dissolved calcium from hard water when you use tap water, etc. It's why a lot of people now use de-ionised/filtered water to mix with antifreeze. If the engine is in constant use it doesn't build up like that.
Methodical and organised as usual. It looks to have had a hard and neglected life. I can't believe all that stuff in the oil pump inlet. It seems you came along at just the right time 😊👍
I added a new sound to my satisfying sounds list: 1. Breaking of morning ice crust on a puddle 2. Popping bubble wrap. + 3. Squeaky click when you start screwing off an old rusty bolt.
Good to see there's still people fixing stuff instead of just throwing everything directly in the trash. I just feel sorry for people who do not want to learn. It's a choice, plain and simple.
Amazing man. Love the journey! BTW, thank you for labeling parts as they show up! Honestly it's such a small thing that goes such a long way. You are the man!
I think, separating a mother with her child is easier than that moter giving up it`s gearbox...🥵 a Big like from me.Luv your vids.Oh yes....Thanx for not playing stupid music in your vids...
This is way much satisfying to watch for me , the way you work and technique and most importantly the tear down as it should be , I'm excited for part two , btw you get a new happy sub 😀👍
I’m amazed you didn’t open that engine to find a thousand broken pieces in it, given the state of the pump, mate. People who don’t maintain their vehicles have no business owning them. My team sergeant in Special Forces used to say, “Stupidity should be painful and expensive”...what I’ve found is that it’s usually painful and expensive for the next bloke who has to fix everything that’s knackered. As for the coolant goo...this is long, but the reading is good and important: BMW has issued a 1991 technical bulletin, 17 01 88(1743), which details problems with what is known as silicate gel precipitation in engines. This is the 'green goo' (yes, it actually says that in the BMW Tech bulletin - gotta love those German translators) that results as a consequence of an antifreeze over-concentration in the coolant, combined with hard water, and the phosphates commonly used in many antifreezes. BMW factory antifreeze has been formulated to prevent this problem of silicate drop-out without any coolant performance loss. This antifreeze contains no nitrites and no phosphates. The part number for a one gallon container is 88-88-6-900-316, and it costs about $13.00 per gallon.
You I just find it amusing the gaskets all of them, look so much better than the parts themselves, they weren't eaten away from the inside out nor the outside in with all that corrosion... I chuckled at that...so funny and weird to see science like this every once in a while.
couple things to help, When using a rattle gun, try to use as little extensions and adapters as possible, all those joints absorb the shocks use rattle guns on stuck bolts, generally thell remove them without snapping them and use the breaker bar more, putting loads of load on ratchets isnt a great idea Nice video cant wait for part two!
I was thinking to rebuild e30 m40 engine but I have not so much experience with German engine so thanky bro for every knowledge you give us 💓💓💓✔✔✔👍👍👍👊👊💕💕💕💓💓✔✔👍👍👊👍👍✔✔✔✔
As for the camshaft, I'd go for a new one (with a bit more attitude!) The rtv in the pick up tends to find its way all round the engine & camshafts that are lubed by a spray bar tend to suffer. Budget for the top end needing more work than normal.
FYI those core plugs (freeze plugs), easiest way to do them is to deform them first. Use a large punch or even a bolt right in the centre and give them a good hard hit with a hammer until you leave a large dent. Deforming them this way will pull the sides in and make them easier to remove.
Anti-freeze makes some weird crystals sometimes.... And that's some very very old anti-freeze probably some ancient weird formula -.-' If it was oil it old be a watery mud like texture.
The stuff that came put of the oil pump pickup was crazy. I wonder if thats why the camshaft and main bearings looked pretty scored up? Great work! love the content!
Thank you very much for this video. I'll definitely use it and pt 2 for reference when I strip mine this winter, it's running a lot better than yours was at first thankfully! There'll be no excuse for headscratching thanks to how clear and free of bull this was, unlike many maintenance videos. Brilliant
That bushing on the bracket over the oil filter housing comes out in two pieces, through the access hole for the bolt behind you push a flathead screwdriver between the two pieces to separate them then push the rear half of the bushing through the back and front through the front. Can then be reused. No need for fire and hammers lol
That crystallized mess in the thermostat is just the result of tap water being used in the cooling system, the calcium just builds up and makes a mess. I saw the same thing in an M20 that I re-sealed for a customer at my shop last week.
The crystals depend on where you are in the world and what your country allows in antifreeze. Here in America that's most likely aluminum added to help seal small holes in the coolant system. It is also the reason why you do not mix different types of coolant such as dec cool and plain green. You get a reaction and it plugs up the works.
Awesome video bud 👍 makes me miss the old days, meeting up with mates and working on cars, stripping engines and making everything better.........or in my case sometimes worse. Good job bud 👍
Nice video again! Small tip for the next time, the caps which hold the camshaft are line bored together with the head, so it's good practice to keep the caps in the right place.
It's the minerals from tap water & glycol from very old coolant. Best bet is to have the whole block "hot tanked" I'd also consider replacing the radiator. I know its a resto but the cost of a new radiator against the risk of an overheated Freshly rebuilt motor?
The crystals are dried up residues from the coolant mixing with aluminium oxide.
When not dried up, its actually a kind of goo clogging up the hoses and thermostat
Cheers K M, It will still kind of gooey, but awful stuff either way!
how do you clean it ?
Before reading this I was wondering if the person had been using tap water instead of distilled with the coolant.
@@crystaldragon141 I was thinking the same thing!
Sometimes it's also some anti leaking aditive product you can add to your coolant
I remember when u got the car and said, it won't be a "big restoration" 😂😂😂 nice video, good luck my friend!
Just a gift for people with an M40--Thank you. Great video.
"Which I then removed with fire and a hammer" .. the best way
fire makes everything easier :D
@@RestoreIt actually, that bushing is split, and you can kinda push it out from the middle to both sides, so you can access that bolt underneath. i remember scratching my head like you did trying to figure it out, and when i moved the block around, one half of the bushing just fell out.
Wait, there is another way?
That camshaft is toast
Awsome.
Thanks Tito4re!
@Tito4re Hold up, i used to watch your Videos quite a lot a few years back :) What happened, why did you stop uploading?
Also it's an example why "Distilled water" not tap water should be used with coolant.
Best is "waterless" or premix.
For sure... I was thinking that was part of the problem.
modern antifreeze can be mixed with tap water. But, i use distilled still. i can sleep in peace :)
Evan's waterless coolant never change no corrosion lifetime warranty
Their going to boil the block anyway
14:41 - Removing the thermostat pipe - that happens when you mix two coolants that don't go with each other. they are lists what coolants you can mix and not.
True dat - BMW uses blue/green (Glysantin G48), if mixed with red/pink (Glysantin G12), than this happens.
Your editing and video production remain among the highest on TH-cam, restoration videos or otherwise. Thank you, sir.

Thanks for letting me know mrman!
fairly sure that it, its a solid, hard yellowy rock that forms on the surface, not a gooey looking crystal.
Methodical and organised as usual. It looks to have had a hard and neglected life. I can't believe all that stuff in the oil pump inlet. It seems you came along at just the right time 😊👍
You really need to invest in a good compressed air impact gun, I think it would be easier for you to work
Very good point. I keep thinking I'm not allowed to make that sort of noise after years of worrying about it. Literally ordering one right now cheers!
@@RestoreIt Wait why wouldnt you be allowed to use a impact gun?
@@FluePeak I might be because it is very powerful and it can brake bolts some times, I don't really know.
@@ulyssepoulain4817 Yeah that makes sense
@@RestoreIt Really love your content man, looking forward to the next episode !

1. Breaking of morning ice crust on a puddle

+ 3. Squeaky click when you start screwing off an old rusty bolt.
man, im so excited for part II ! best cliffhangers on yt!
Haha cheers Callon!

How many first there are??? 😂😂😂😂 Oh boy here comes another great video to start a great weekend, love this engine restorations.
A strong third from you man. Cheers!
"Which I then removed with fire. And a hammer."
Sounds like he and I share the same philosophy when removing stubborn things.
Must say for the mountain of work you do, one of the few times I’ve seen you snap a bolt. Keep it up m8!
Excellent work! so excieted, thank you!
Great lighting in this episode - the dirt comes alive!
Как всегда - красота! Аж глаз радуется!

@@andreikashin 1 провод приходит от катушки и 4 уходит на цилиндры. Как у всех.
That was in a pretty rough state! I'm surprised it ran at all. Definitely in need of a rebuild, I'm looking forward to seeing it come back together.
Hello from Belarus🤚
I have e30 with m40 too, but saloon.
And is't so interesting and helpfull watch your videos about m40.
Keep it up🤘
I know nothing about cars but love watching your videos ☺️
This is exactly my engine and you just uploaded this recently, i feel blessed
Best youtuber ever
Thanks Waleed! A stretch, but I'll take it
I think, separating a mother with her child is easier than that moter giving up it`s gearbox...🥵 a Big like from me.Luv your vids.Oh yes....Thanx for not playing stupid music in your vids...
Love your vídeos
Thanks Marisa!
I think this series will come in handy when I am restoring my M43B18, they are different but in a few ways similar
I feel better knowing this engine will get restored.
Great video as always. You've inspired me to start rebuilding the M42 that's been collecting dust in my garage for the past two years.
I could watch you work for hours.
Looking forward to the cleaning and paint of this engine.
This channel just keeps on getting better and better. Love your work!
Yes, the clogged pipe is a result of the residual coolant sitting on one side of the closed thermostat for a very long time.
Excellent restoration video
This is way much satisfying to watch for me , the way you work and technique and most importantly the tear down as it should be , I'm excited for part two , btw you get a new happy sub 😀👍
Great video mate, a lot of work, and the best thing is you have a video to play when you can't remember where everything goes back.

Barring the oil sump pump that one doesnt count....cause that isnt a gasket as much as goo.
So therapeutic my restore it armchair spannering sessions great vid can’t wait to see the finished before and after pics - fantastic 👍
It's amazing to see an engine together & then it's in pieces! Great job & I can't wait for the next video!

Your videos are inspiring. Fearless! That engine has had a hard life - it's lucky to find you. I'd love to see you restore a BMW 2002 one day.
As a SMA fan. On inspection of the oil screen. I can safely say.
“Well, There’s your problem lady”. Looks like a good core for a start.
Always impresed by the quality of your videos. I´m hyped for the outcome and the journey to get there.
FYI those core plugs (freeze plugs), easiest way to do them is to deform them first. Use a large punch or even a bolt right in the centre and give them a good hard hit with a hammer until you leave a large dent. Deforming them this way will pull the sides in and make them easier to remove.
That motor definitely needs rebuilding. Great video

If it was oil it old be a watery mud like texture.
Maybe its just that then. I feel like this engine has never been looked after so it might be the case...
Great stuff and loved watching the tear-down! This engine has seen a lot of hard miles. The junk stuck in the oil pump was staggering!
Wow this is the first of your videos I have seen but i am very impresses really interesting and educational. Thank you.
If you will manage to save that engine...you will be the next Marvel superhero! But I am watching you for more than 1 year and I know you can do it!
21:47
I knew it
Camshafts wear as I said previously
The stuff that came put of the oil pump pickup was crazy. I wonder if thats why the camshaft and main bearings looked pretty scored up? Great work! love the content!

Awesome. Just thank you. I drive an E30 318i Cabriolet and maybe in the future I want to restore my m40 by myself. Good video.
After two years, I don't want to restore it by myself 😂 well, maybe. But not now.
Wowow wee wow, been waiting to see your video Steve!
Hey man! Cheers!
Thank you very much for this video.
I'll definitely use it and pt 2 for reference when I strip mine this winter, it's running a lot better than yours was at first thankfully!

That goo is an additive to stop coolant leaks. Mainly in radiators. It is supposed to be a temporary fix to get you home or to a repair shop.
Love the attention to detail with removal!!!!!

Back to old days. Great
Dirty beat up vans are a vibe when working on an engine. Love the aesthetic

You are a professional in both working and editing your videos and definitely deserve a subscription. Keep up the good work mate
I wonder what Sreten would say about the condition of that engine.
Coooooming up
Lots of swearing. Look at those clogged oil/coolant jackets. My lord.
AND THE RTV!
Great! Love those mechanics episodes over a bodyworks.
The gel like substance in the coolant thermostat etc. will be due to different types of antifreeze being mixed. The chemicals react with each other.
this is gonna be a great serie..

greetings from Turkey E30❤️
Use channel locks for freeze plugs, you can use the block as leverage and it’s a lot less of a hassle
Because of the worn out camshaft lobes you should check out if the holes in the oil rail above the shaft are clogged. It happens a lot.
Really looking forward for the next video man.. great work
Been looking forward to this one. hows the recruiting going?
Cheers Rob! Not bad, quite a lot to get through!
@@RestoreIt good stuff, glad you are being kept busy lol

Try dry ice blasting to clean things up without any chemicals and maintains original surface and texture
Only a couple broken bolts, and fortunately they still have stubs sticking out you can grab onto, so hopefully they won't be too difficult to remove.
Great!!!
I'm looking forward to Episode 2
The thought of dismantling an engine, scares the shit out of me😂
Great video man, thank you. Well done
Watching you from your start, pretty cool videos 👍👍👍
Lovely long video. Just what I love to see. 😊👍.
wtf, great man, please part 2 fast in a hurry
Great watch with a cuppa!
I have rather a noob question, how do you keep track of every nut and bolt location? do you label them?
Yeah if you look at the end of the video, you can see the tubs i use. I thought I'd show that process this time
So nice to watch! Very very well done! Greetings /Peter
Excellent video - thank you! Cheers!
PERFECT! love every video, this is so interesting! THANK YOU!
Judging by the state of that engine, the camshaft damage was due to clogged holes in the oil spray bar...common issue.
bar/psi oil pump , worn out camshaft/lifters ?
