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.
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.
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 TH-cam channel 👍
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.
I'm not mechanically-minded myself, but this series is fascinating and most enjoyable. Two real gentlemen, too. Sadly, an endangered species. Thank you.
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.
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.
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
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.
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.
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.
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.
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!
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!😋
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!
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.
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.
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.
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.
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!
Out of all the TH-camrs I watch on TH-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......
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.
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
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.
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 .
19:47 Just talking about the weight on these vehicles is fascinating. Bits of comparable information and commentary that's difficult to find elsewhere.
Well that’s made my day! And Ian’s new TH-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!
Lovely Christmas present, this installment. I could listen to both gentlemen all day. That shop is to die for,xand the cars inside are simply magnificent. Great craftsmanship and attention to detail. Watching this series has motivated me to plod along on my restoration projects. The final result will be a spectacular Espada. Cheers
Love these engine rebuilds. I've had a few done myself. Amazing what the guys do. Got a 65 Cooper in being rebuilt at the moment. I was playing with valves myself last week.
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'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.
Good for you with the Zircotec coatings! Now you can go one more and coat the pistons crowns and skirts for Lower coefficient of friction and much reduction in heat transfer on the piston. Its all in the details.. If you wanted to be really fancy you would also coat the valve areas inside into combustion chamber.. If you've ever seen a valve going up and down at 7k rpm they practically turn cherry red.. Magnificent work BTW. The shop you're working with are true pro's.
I'm so pleased that Ian Tyrrell has started making videos about his amazing work. I'm sure they will be a huge success. In fact the two of you together are superb to watch; I hope you do more together. Where else will you see THREE Espada's in the same workshop getting properly sorted out.
Really enjoy watching the Espada rebuild...having owned a series 3 here in Australia, I can relate, however I wish we had mechanics with Iain's experience and knowledge with Lambo's here as I had to send my engine to the USA for rebuild which cost more than I paid for the car! Keep up the great videos Harry.
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 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 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 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 TH-cam channel 👍
Put my name down too!
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
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.

Great result last night, onward and upward....
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!
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.
I'm repeatedly impressed by Iain's extreme Lamborghini geekery.
"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.....
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.
There aren't many channels I actually make time for and watch all the way through. Harry's is one of them.
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
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.
This has been a fantastic series, absolutely loving it.
Ian has now his own channel. My life is now complete. Lovely
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
Great to see an owner drive a great car, and even better to see the rebuild. Thank you so much
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.
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!
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.

Thank you all.....its a blessings ...

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.
Good to see that Mr Tyrrell reads the comments section! and went with the recommended ceramic coating on the exhaust manifolds.
As a lamborghini nut since i was 8 years old, (I'm 40 now), this channel is pure gold! I love it!
Just really great Harry. I could watch you and Iain talk all day long.
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!
I've been waiting impatiently for this installment!
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!
Just reading comments and clicking thumbs up everywhere, these videos are just so good, they evoke great positive commentary.
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.

Stunning! So glad people like Harry exist in being custodians of our history and preserving it for future generations, this is so important.
Great stuff ! Whole series best all year !
The world needs more of you! Thank you Harry for keeping the level up!
I thought Harry was the man but so is Iain Tyrrell.The best 22 minutes viewing in some time.
for me this video was priceless. Maybe i'm a geek. I was mesmerized by the explanation
I could listen to these two talk all day about these cars. Fantastic! I was waiting for the comment about prior visit monsoon. 👍
Thanks for prodding Ian to start his own channel. You two are fantastic too watch!
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.

22 minutes goes fast , so glad the wizard has created a channel for us to binge on
Well done Harry getting the Tyrrell channel started. Now in my top 3. He is so interesting explaining things. Mine of information
A hug from my daughter and listening to these guys...same level of bliss :)
I grew up in the 1970s reading Road & Track magazine.

Love this sort of presentation instead of just burning donuts and spitting out performance facts.
With the amount of knowledge and info these two have you could write a book on Lamborghini history.
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.
Again Brilliant chat between Iain and yourself.... Fantastic and awesome to know Iain has started his own channel

Thank god for Harry, this guy is a proper automotive expert.
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.

Tyrrell's Classic Workshop on TH-cam - YES!
Such a pleasure to watch the rebuild, cannot wait to see the car finished and hopefully a road trip to the Swiss alps.
Two of the very best channels on YT.
Harry, without doubt the thing that comes across whether you're talking Farm or Garage, is your enthusiasm!
It’s a work of art what Tyrell do there. They have a TH-cam channel you say, they got a subscriber
Thoroughly enjoyed this video Harry. Tq so much for posting. Regards from Malaysia.

Love all the detail on the engine, cam lift, valve spring force etc. Just a great series on the Espada.
Man, I have no words, that professional is like a wizard
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 .
Brilliant stuff. I could listen to these chaps all day!
I Build the Vertikal Tail Plane for the new Belugas, here in Stade, Germany. Nice to hear them start while watching your video ;-)
That early XJS looks lovely.
There is only one word to describe what Ian and his staff do with cars. Craftsman.
19:47 Just talking about the weight on these vehicles is fascinating. Bits of comparable information and commentary that's difficult to find elsewhere.
Well that’s made my day! And Ian’s new TH-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!
Harry, you can apply clear film on the glass roof that will help with the sun rays and heat, but not take away any of the clearness of the glass.
Just love this V12 build thread,, cant wait to hear it at 8K...
This is pure gold, Harry.
I could watch these all day.
Lovely Christmas present, this installment.

" It's a horn- when you get to the rev limiter". LMAO. Brilliant.
like the rx7!
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
Excellent as always, absolutely love Iain's incisive knowledge of classic Lamborghinis
Just got done rewatching part 2 and 3. Perfect timing.
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.

I’ve been waiting for this update! Thank you.
Here’s a new one for you... I am coming to you from Ian’s channel. Both are now on my “never miss” list.
These are absolutely brilliant, the engine looks brand new and run like new. Fascinating guy.
Great video as always Harry. And now we have something else to look forward to on a regular basis. Eagerly awaiting the first instalment.
I am no car buff but I do enjoy the videos, excellent once a again and really good conservation between Harry and Ian
I'm so pleased that Ian Tyrrell has started making videos about his amazing work. I'm sure they will be a huge success. In fact the two of you together are superb to watch; I hope you do more together. Where else will you see THREE Espada's in the same workshop getting properly sorted out.

Really nice walk around.Just the level of detail and so relaxed.Keep it up
I didn't know how much I didn't know about engines, but I do now. Love these videos and looking forward to more of the same from Iain Tyrrell.
I have always loved the Espada since they came out. I saw a Marzel in the flesh as well at a motor show here in NZ way back in the 1960's.
