Lamborghini V12 engine rebuild Part 4. Upgrading it to Miura spec
Вставка
- Опубліковано 4 жов 2024
- The engine in my Lamborghini Espada is currently undergoing a full rebuild after it started losing cooling water when we were on the Lamborghini Espada 50th tour last September. Here in part 4, the components are back from cleaning and machining and Iain explains how we can make the engine closer to Miura spec. Watch Iain Tyrrell's new UA-cam channel here • Lamborghini Miura S & ...

I think we've got very lucky with that bloke starting his own channel!
Hell, yeah!
I'll second that!
Every vid a joy ...
100%
Harry's channel is such a welcome relief from all the nouveau-riche 10 year olds running around buying Lamborghinis that have no appreciation for the history of the sports car and no real ability to describe what it's like to own and drive these cars beyond their exclamaing how cool they are.
22 minutes of automotive bliss.
Agreed
This chap really does know his spanners!
Yes a lot better than I do.....he wouldn't want me there... :-)
Scott Harker And wrenches.
@Pollywog he does know them BY NAME
This guy is a professor. Could listen to him all day long
2:05 The difference in valves between Maserati and Ferrari engines with Lamborghinis, he knows his stuff!
@Lord Rupert Lol how so?
I think the hollow stem is completely filled with Na. Heat from the valve head is conducted rapidly to the valve stem and thence to the valve guide in the cylinder head, which is water cooled. This was required in two valve high performance engines. Use of four valve heads decreases the specific valve heat loading.
Was Iain joking about when he said about when he started his career with Rolls Royce/Bentley he didn't use a torque wrench lol and if anyone walked in with one you'd be fired 😳
@@spacedust2270 Possibly not. I have heard that RR nuts and machine screws were so well made that hand torque with the appropriate swan neck ring spanner was all that was required. When the spanner just begins to flex, the nut or screw is just tight enough.
I will pay for a two weeks holiday working in this shop, with this gentleman. I very much fancy this instead of a beach resort.
He is great, another place in England iou might like to work on vacation is the Tank Museum in Bovinghon. Check out their work rebuilding tank engines on their UA-cam channel 👍
Put my name down too!
A new Lambo engine rebuild video, Iain launches a channel, a huge Tory landslide and a big jump in the value of the pound. Days don't get much better than this. I enjoy all of Harry's videos (cars and farm), but this particular series has been exceptional. Sodium used in valve stems to dissipate heat - I had no idea. Iain is fascinating to listen to and I look forward to his channel very much.
Great result last night, onward and upward....
"Death rattle par excellence" lol superb sentence about broken Ferrari sodium valves :)
I liked that.
YOur exhaust valve loose in the cylinder aint gonna sound pretty.....
I'm repeatedly impressed by Iain's extreme Lamborghini geekery.
I'm not mechanically-minded myself, but this series is fascinating and most enjoyable. Two real gentlemen, too. Sadly, an endangered species. Thank you.
They are the same like these old cars. Charismatic and with a heartful of soul!!
Don't give up hope, I'm skint but am an english gentleman at heart!
Ian has now his own channel. My life is now complete. Lovely
I'm not even that mechanically inclined but have been loving this series so far. The whole ambience of the workshop and all the love and knowledge on display from both of you, brilliant.
There aren't many channels I actually make time for and watch all the way through. Harry's is one of them.
Another fine video. Mr. Tyrrell's knowledge is amazing. I encourage him to write a book. It would be the bible for all exotic car restorers.
Great two Gentlemen. It is so relaxing and fascinating to see that Car Channel. No fast Videocuts, no Timepressure, no Beers, no Chics, no Wheely Donuts and it works.
That engine is like jewelry! Can't wait to see it back in the Espada!
Thanks Harry! We now have two knowledgeable, charismatic gentleman to tune in to. Bloody brilliant
Am I the only one that has been waiting for another update on this project? Great series!
Daniel Schmidt no!
I doubt it very much!
With the amount of knowledge and info these two have you could write a book on Lamborghini history.
for me this video was priceless. Maybe i'm a geek. I was mesmerized by the explanation
My god, theres not another car channel as good as this. The detail, the language, no dramatisation, just pure knowledge. Thanks Harry.
Subscribed to Ians channel too.
My good friend is a physics professor. He once took me to Fermi Lab outside of Chicago. The particle collector on the super collider was taken apart. I wanted to quit my job, move there, sleep on a cot and make coffee for those folks. It was awe inspiring. I feel the same way about Ian.
Engineering and Art combined, that's how it looks like. There are many great 2+2 cars to choose, but I think this is my favorite!
Great to see an owner drive a great car, and even better to see the rebuild. Thank you so much
This has been a fantastic series, absolutely loving it.
It is not enough that Harry gives us this gems that his videos are, and now we also have a spinoff that has potential to be one of my favourites in youtube! Awesome
Love this sort of presentation instead of just burning donuts and spitting out performance facts.
22 minutes goes fast , so glad the wizard has created a channel for us to binge on
Good to see that Mr Tyrrell reads the comments section! and went with the recommended ceramic coating on the exhaust manifolds.
That early XJS looks lovely.
My best viewing of the 'Harry's garage' series re the rebuild of his engine, I've learnt so much just by watching these two gents talking.
As a lamborghini nut since i was 8 years old, (I'm 40 now), this channel is pure gold! I love it!
Tyrrell's Classic Workshop on UA-cam - YES!
So enjoying this mini-series on the Espada. I think the combined auto-knowledge of both Iain and Harry exceeds Google! An absolute joy to listen to these gentlemen. Subscribed already to Iain’s new channel. Wish him good luck with the new venture.
It's been a lot of fun watching these videos. As an American enthusiasts, I rarely get a chance to even see cars like this. Let alone see what's involved in it's resurrection. So many things to consider. So many things to wear out and need replacing lest one does severe destruction. And to understand what's involved in the purchase and ownership of a car like this. I've been watching these out of order. This doesn't seem to matter as one is as enjoyable as the last.
Thanks for prodding Ian to start his own channel. You two are fantastic too watch!
Just watched the film about the Miura auction on the german grip channel. Now the yellow beauty is in the same workshop as Harry's Lambo. Just great stuff!
Just really great Harry. I could watch you and Iain talk all day long.
I thought Harry was the man but so is Iain Tyrrell.The best 22 minutes viewing in some time.
Thank god for Harry, this guy is a proper automotive expert.
Man, I have no words, that professional is like a wizard
I think this has been one of the most enjoyable series of videos I have ever seen. Bravo. And at the end of it all, the Espada will be started up - what a moment that will be.
What great guy, Ian is. Absolutely impressed in the way he goes about his work and his knowledge. I worked shore based for a trawling company in Aberdeen back in the 70's who had two trawlers with Polar V12 main engines with sodium exhaust valves and they "dropped" a few valves over time. What a mess. New piston, liner, head, turbo and damage to other cylinders. Total strip down and a tow back from the fishing grounds.
So that's how the sodium is incorporated in the valves. I had just assumed that technology simply had a fully filled core inside the stem, and that the sodium had better heat transfer properties than the outside. Fascinating !
Laz Arus it’s also that the sodium is going through a phase change from liquid to gas at 838C, which is a really hot exhaust valve temperature, so it can absorb a large amount of heat and hold a constant temperature. Like an ice cube in a glass holds it 0C.
@@EdwardT9 As a followup, I read that also. Similar in principle to how some of the tubular heatpipe heatsinks work that you find on PC hardware these days.
This is just excellent stuff! So much knowledge, no irritating music, just talking! Love it!! :)
Perfect. Anything less than this kind of perfection wouldn't be doing a car like this justice.
The world needs more of you! Thank you Harry for keeping the level up!
Just reading comments and clicking thumbs up everywhere, these videos are just so good, they evoke great positive commentary.
Listening to intelligent people talking is so refreshing. In an era of flat out rubbish I think people will appreciate it more than ever. Thank you.
I agree totally!! Thanks for this comment!
Amazing, Ian has all these measurements in his mind, so and so many millimeters!
I wish I could wind the clock back 30 years and serve an apprenticeship with this chap, his knowledge and experience is awe-inspiring. That red XJ-S in the background looks pretty special too. Like good wine and attractive women, old Jags get better and better with age. Didn't Gambit in The New Avengers have an early XJ-S in red, or was his yellow? My memory is letting me down a bit. I remember the yellow Rover 3500 Steed drove, and the dark green Broadspeed XJ-C with the utterly fabulous Gene Hunt Wheelarches. The car's of my childhood are so much more appealing than today's offerings. I wonder which cars of today our children will be hankering after in another 30 years though.
After watching Ian videos many times , I realized most of his dialogue is off Q cards, look at what his eyes are doing. He is still the best car whisperer ever
I could listen to these two talk all day about these cars. Fantastic! I was waiting for the comment about prior visit monsoon. 👍
Here’s a new one for you... I am coming to you from Ian’s channel. Both are now on my “never miss” list.
Stunning! So glad people like Harry exist in being custodians of our history and preserving it for future generations, this is so important.
Thank you all.....its a blessings ...
It’s a work of art what Tyrell do there. They have a UA-cam channel you say, they got a subscriber
What a complete joy to immerse oneself in exotic Italian engineering and to totally escape from the world of politics. 21 1/2 minutes of bliss! Thank you! Now, I’m going to watch Iain’s video, and I know beforehand that it’s going to be another deep joy to watch!😋
Amazing. That workshop is Paradise.
Just love this V12 build thread,, cant wait to hear it at 8K...
What a great way to kick off a dull, damp day!
Well done Harry getting the Tyrrell channel started. Now in my top 3. He is so interesting explaining things. Mine of information
Two big boys with big boy’s toys.
Excellent stuff, I’ve enjoyed every second of this video and other videos too.
Thank you for posting.
A hug from my daughter and listening to these guys...same level of bliss :)
There is only one word to describe what Ian and his staff do with cars. Craftsman.
Probably the most enjoyable series of videos I have seen on YT. Clearly classic car ownership is a real labour of love! We are so lucky to have the geniuses!
I grew up in the 1970s reading Road & Track magazine. While kids in my school were reading Hot Rod and dreaming about the latest Camaro I was the weird kid dreaming about Ghibli’s, Miura’s, Daytona’s, Alfa’s, Citroen’s, Lotus’s, etc. Espada, Jarama, Uracco/Jalpa were all cool cars. It bugs me that so many people throw shade at them because all they can identity Lamborghini with is the Miura and Countach/Diablo/Murcielago/Aventador. I think the Espada is fantastic. Nice that you’re giving one some love. Kudos.
Great stuff ! Whole series best all year !
Such a pleasure to watch the rebuild, cannot wait to see the car finished and hopefully a road trip to the Swiss alps.
Brilliant stuff. I could listen to these chaps all day!
Just got done rewatching part 2 and 3. Perfect timing.
These two guys are fantastic together! So much passion and knowledge.
If I ever scrap enough money together to buy a old V12 Lambo I'll buy one with a knackered engine and get Iain to rebuild/ mod it for me............. Please lottery tickets make this dream come true 🤞🤞🤞🤞🤞🤞🤞 loving these videos Harry 👌
I'm loving this series, thanks. Brave chopping the roof but it will add a new dimension to your enjoyment of the car. I've always had a soft spot for 4 seater Italian exotica. If only I could go back twenty or thirty years with a bag full of cash.
Could watch this all day long
Thoroughly enjoyed this video Harry. Tq so much for posting. Regards from Malaysia.
Out of all the UA-camrs I watch on UA-cam I enjoy Harry’s content the most...... it appeals to the enthusiast and engineer in me...... Absolutely Love the channel and look forward to the new content......
Thank you Harry for this episode!
Craftsmanship at its finest.
Nice Video
I would have fitted new valve seats as the copper beryllium ones do not hold up so well with modern fuels . You can see how far the exhaust valve is recessed into the seat and no top cut on the seat .
So cool Iain has his own channel, I could watch him all day just wrenching these cars! Harry is just too cool.
Harry, great video as always, facsinating to see the process and how easily Iain can talk you into little tweaks and upgrades! Thanks for talking Iain into starting his own channel as well - just watched the first episode and it is great to be able to watch a series like this without the presenter screaming at you about the latest crisis that they are facing. Long may it continue
Well that’s made my day! And Ian’s new UA-cam channel. Once I have finished watching this I will subscribe. Harry, I love your content but this series with Ian is wonderful, more please!
So refreshing
I am no car buff but I do enjoy the videos, excellent once a again and really good conservation between Harry and Ian
Watching the rebuild series in Covid isolation and it's fantastic. I love these cars but had no clue how they were engineered. Ian's engineering knowledge is incredible. Would trust him with my Miura if I ever buy one!
Excellent video Harry..! I am glad to learn about the internals of these V-12s. Some one in Palo Alto CA wanted me to rebuild one of these for his Miura S back in 1989.
This is pure gold, Harry.
I've been waiting impatiently for this installment!
Harry, without doubt the thing that comes across whether you're talking Farm or Garage, is your enthusiasm!
filmography is impressive as always. They always get the right shots and close ups.
Really nice walk around.Just the level of detail and so relaxed.Keep it up
Again Brilliant chat between Iain and yourself.... Fantastic and awesome to know Iain has started his own channel
These are absolutely brilliant, the engine looks brand new and run like new. Fascinating guy.
I’ve loved watching this mini series so far. So interesting.
Excellent Channels from both guys. I have been ill lately these guys have got me through some trying times. Thanks to both of you. Cheers Barry,
Popcorn ready, love these rebuild films.
Wonderful to see the progress and Iain’s expertise.
Thanks for sharing gents
👍👍
Love all the detail on the engine, cam lift, valve spring force etc. Just a great series on the Espada.
What a joy to hear real engineers talking...people who really know their job and unpretentious in every way. I shudder to think what the costs to rebuild that engine will actually be but the results will be exceptional. I have always dreamt of owning a P400 but the Lottery win is still in the post...now I need to save for the chassis upgrade as well...oh well..it’s only money😱😎😎😎😎
Was just wondering when the next part of the Espada rebuild would be up. Can't wait to see the engine being rebuilt in the next one, it's fascinating.
