Lamborghini Miura - Tracing a running fault to a 17th century invention | Tyrrell's Classic Workshop
Вставка
- Опубліковано 31 тра 2024
- This stunning Lamborghini Miura finished in Blue Speciale was lovingly restored by Iain and his team 4 years ago. It has returned for a service but has a running fault that Iain suspects may be as simple as stale fuel after low recent usage. After some detective work, Iain identifies the real culprit, whose technology can be traced back to a 17th century invention for windmills that would then form an integral part of steam engines!
Iain sets to work on rectifying the issue, before piecing everything back together for a quick tune up, before taking her out for a road test to see if the running fault has been resolved.

One of the things I love the most about this channel is that not only is the content really good, but while you listen to Mr. Tyrrell saying all of these interesting things, there's all this stuff in the background as well! No need to make up a set or travel to a location-just film in the workshop. I love how there's always an interesting Diablo, or a casual Ferrari (or Harry Metcalfe's Espada!) in the back of shot. It's a way better setting than just about any UA-cam channel could ever manage, regardless of how big their budget is.
You nailed it on all counts!
One could argue Jay Leno has more interesting stuff in the background - but he has obviously different resources, so to speak.
The distributor work and education was wonderful, but Iain, I must say, the pure joy of driving that car is so clearly coming through to the viewer. Just glorious. Thank you for bringing us along.
Every time Ian gets to put his foot down in a car that he's sorted the engine on, there's that excited "WOOOO" and a massive grin. The love of cars (and driving them) really shows through.
I think I would have used a plain grease or perhaps MoS2 grease. Copper grease isn't really meant for parts that are "rubbing".
But great video as always 🙂
Exactly my findings, too. (...in over 40 ys)
I’ve seen those distributors for decades and never had ANY idea how they worked. This video gave me a glimpse. Thank you.
I love it: "the loud pedal". That's some ear & touch to set up all 12 carbs. Just a wee twist to each, not too rich, and make the engine burble away. No laptop and some whiz-bang internet download. That is engine tuning at its finest. A joy to watch.
5:23 in one sentence you've explained spark advance in an understandable way. In my 20 year of 'car enthusiasm', I've never understood it so clearly. Thank you Tyrrell.
I've another 20 years on you and totally agree with you. It's so simple when Mr T explained it.
Thats because 20 years ago dizzys were a thing of the past in cars
I had a similar moment a while back when Iain explained he was putting cheap, nasty oil in a rebuilt engine. I was initially horrified thinking it should be super duper synthetic, but cheap nasty oil he explained allows the mating surfaces to bed in properly! Then after it's been run on they will swap to the good stuff. It all makes sense now.
Ian did it so well, but didn't even touch on how changing the springs and weights can change the advance curve, or how the changes in fuels from the 1960's to now means cars like the Miura need completely different curves to what they left the factory with, or how combining those mechanical advance units with a good vacuum advance gives a load dependent ignition curve, which modern computer based systems use many more sensors and some very complex coding to match.
The real advantage of the modern systems, is that they are far more maintenance-free then older methods.
@@johnsmith1474 Just about sums up a mechanic / technician as they are know now .Oil filter basic service and fill in the paper work ,it's all most know .With the garage's charging £100 an hr
The Miura V12 symphony orchestra!! What a stunning machine on every level. Just EPIC. Many thanks for sharing Iain- fabulous!
Someone recently proposed the question ‘In the era of electric cars, what would you do with your last tank of petrol?’. I think the last 90 seconds of this video answers that question.
Remember years ago, you could get T/Shirts, Mugs, etc with the slogan `GENIUS AT WORK`.....Never has anything been so adept.....Someone please find Iain a T/Shirt or Mug !!!!! I could watch and listen to Iain for hours, Iain you need to write an Autobiography of your life !!!
Iain is the definitive master of his art... Genius, combined with an obsessive devotion to excellence and the ability to assemble a team up to his standards, are what separates the best of them from the rest them.
If I manage to get even half as good at my work, as Mr Tyrrell is at his. I shall leave this world one very satisfied man.
That smile when it accelerates... Priceless.
The engine shot without the rear clamshell is magnificent!
The smile on Ian's face when he guns the car just made my day!. Yes, do feel like a 16 year old pushing dad's convertible on a covert drive while he was away....
OMG! The end of the video was fantastic! The sound!!!!!
Take care of yourself Iain, we need you.
Someone that truly enjoys his job and shares that pleasure with us. Nothing else on UA-cam is so relaxing and thrilling at the same time!
Well put. Relaxing and thrilling at the same time. Definitely knows what’s what.
True!!!
All things aside...can you imagine what those little contacts must be made of to withstand the constant opening and closing each revolution of the shaft?
Tough little buggers...
*This must be one of the very few channels on UA-cam that a "dislike" could not be justified :)
What a brillinat vid again. Nothing is more relaxing (and educating) as having a good glass of red wine and listen to Iain explain stuff. Thanks!
When your engineer uses a paint brush you know you're on to a winner. Very educational Thank you.
Obviously these are edited highlights, but even so, how many people in the world would be able to trace that fault with an "oh of course, that'll be a broken spring inside the distributor" ?? And the explanation and repair are just a joy to watch.
I well remember drooling over Lamborghini’s at the London motor show around 1970 and being amazed at all those carburettors, that reminds me I must get out into the garage and service my lawnmower ready for the first cut of the year.
In a world of take off and bolt on a new part, watching you is a delight. Thanks for these videos you keeping the world of proper engineering alive.
Had that problem on the Lucas DMBZ6 distributor on my Mark 2 Jaguar. I also had fitted Pertronix electronic ignition and Lucas Sports coil (in gold). Had to replace HT leads, distributor cap and rotor arm to prevent the very high voltage spark tracking though. Once sorted out went like the clappers though as fuel combustion became more efficient and the twin SU’ s became far easier to tune.
The sight of a Miura driving around with its rear clamshell off and engine exposed to the elements , must have been quite something for others to see..excellent episode once again! Thoroughly enjoyed every minute..
I was worried about rear wheel throwing rocks to the carbs.
The video shots of the V12 without the rear bodywork are magnificent. Then cutting away to Mr. Tyrrell's big smile behind the wheel to match our own. Kudos to the videographer.
Our Videographer, Jonathan Whipp is excellent indeed! Thank you for those words have duly passed them on to him.
I've rarely been more enthousiastic. My God, that engine sound is such music to my ears! From the bottom of my heart, thank you for making these videos.
There's something just glorious about the sound of a weber carburettor.
That engine was the quietest engine I have heard in ages. It sounded like no lash at all. Smooth and quiet.
As a kid I grew up with the Countach. I would kill to drive one, but somehow an opportunity to ride shotgun in this would be on top of my bucketlist.
I'm so glad to see that there are examples that get driven properly and not stored as garage queens. Let's enjoy these things while when still can.
Thanks for sharing Iain, you really make us feel part of your world.
My father walked in and thought I was watching Keir Starmer show off his car!! Great video as always.
Now that is a true 12 cylinder engine sound. Racy, growly, spitting and spinning. Great video Maestro.
The mini Miura keychain at 15:26. Gotta love it! The most beautiful car ever made, in my eyes. Luckily, at 6'2", knowing I can't really drive one helps accept the fact I'll likely never be able to own one. 😂
That shot of the carbs and throttle linkage at work was awesome.
Oh please, I've just finished watching Harry and his Jag and couldn't wait to check your wonderfully technical and enthralling diagnosis. Thankyou Iain, wonderful stuff, oh and the induction....bellisimo.
I miss this technology. This is the best explanation of ignition advance I've heard. I might make this compulsory viewing for the apprentices.
O M G … that V12 sound is an incredible RUSH!
I only meant to open the video in a new tab to watch later but it was so interesting straight off the bat, that Im still sitting here, 10 minutes in! Well done Iain!
I think I just fell a little more in love with the Miura, how mechanical it is.
"Every day's a school day" - Love Iain's humility and amiable manner - like the best kind of teacher we all wish we'd had!
Also, the step-up in camera work really noticeable on this video with the engine shots and driving sequence at the end. Superb stuff. Many thanks as always.
Another content creator making "mainstream" media programming BS obsolete, and good riddance to it!
He must have driven it without the rear bodywork to get those engine shots!
5:15 this is where the saying balls to the wall comes from. When they’re all the way out towards the wall the engine is working as hard as it can.
What a beautiful restoration... Interestingly the most modern upgrade is the bit that let it down. Superb example of Italian craftsmanship in the hands of a well seasoned oldskool British engineer. What a peach that car is !
18:33 The sound! Beautiful music. Induction noise is just plain rude. Very nice.
What more can one say. It's almost an ownership experience watching your films, as you are seemingly talking to 'me' about my Miura's problems - if only.
That's the most beautiful Miura I've ever seen, what a colour. Great video.
I understand very little in mechanics, but just listening to this channel makes me feel good :)
Ahhh the internal combustion engine. We’ll miss you when you’re gone. Just the whine of an electric motor to look forward to 🥲.
Stunning car and soundtrack Mr T.
Keep up the good work 🙏
and the whine of disgruntled owners queuing up to get a "quick" charge...
I'm looking forward to the runabouts and suvs in all having a gentle whine in my neigbourhood. I'm sick of the fumes and noise in London. It's a depression of constant asthmatic exhaust notes. Iain's cars are symphonic rare beauties. They'll be loved and cared for (lord knows his customers have the cash!), running on biofuel - occasional music for the soul while 99.99% of the rest of the boring ICEs in the world go the way of the dodo. Happy days that can't come quickly enough.
Had to watch this video twice to really appreciate the sound from this engine - Symphony for 12 pistons...!
Fascinating mechanical solution but when you compare mechanical points and carbs to modern electronic ignition and injection, you can see just how far we've come since these were the standard. The gains in power AND fuel efficiency with the modern hardware are quite significant. However there is a lovely sense of satisfaction seeing how it all works in the mechanical solutions.
Grazie! Grazie Mille!
What a treat to listen to Iain's narration, then those carburettors!
Placing the camera inside the engine compartment is such a kingly gift for any enthusuast.
Thank you, you made my month....
What a great sound of a V12 going to nearly red line and back down again. Love it ,
Like watching a composer tweak a perfect symphony. Nice work Iain!
Iain's workshop looks like it always has some Muira's in for some work in the same way there is always a focus at a Ford dealership. Excellent work as usual! True craftsman.
A case of muriaitus
There is always a focus at any car garage.🤣🤣🤣
I believe that 72% of all Muira's in the world are in a garage at any given moment in time. 12% are broken down waiting to be recovered. 6% are on their way to a garage and 10% are running brilliantly.
Posting comments here is pointless. He doesn’t care or read or reply.
@@eireaontaithe5760 really?😎
Well done Iain! That sound was glorious! No greater symphony than a Classic Lamborghini V12 with quad triple choke Webers!
Beyond the very interesting automotive content, it is a pleasure to watch the impressive personality of this dignified British gentleman. His ability for self-mockery is extremely sympathetic and can probably only be found in Great Britain in this way.
As a faithful viewer, I love all your shows Iain, but this in particular is one of my favourites; you doing what you do best, tracking down problems and literally optimising classic bits of gear. I still love your test drives and stories though.
Oh to be you Ian. It must be a joy to awake each morning.. Keep it up, your installments get me through the week. Many thanks Sir
Nice to see that Tyrrell’s workshop and my garage have something in common. Cardboard on the workbench 😁
Mate I expected you to say a Miura ;)
@@SerbanCMusca-ut8ny I'm also here for the comments:)
Another non fan then of that terrible sound of precision components being dragged across contaminated metal surfaced benches?
No wonder you are the go-to guy for the marque Iain. Excellent work.
One of the best channels on youtube for petrol-heads. Love to see an episode on your story, your car history and how you got started in restoring cars. And lastly, love to see an episode on refreshing, installing and tuning a weber carb.
I'd be more than happy to watch a detailed tune up from start to finish.
Nice to see you at your 'desk' explaining everything - and you wear the Miura so well, sir! What a GLORIOUS sound those twelve bulls make!
As someone who is just starting Their life as a automotive tech it's my dream to work on vintage Italian cars and this was a real joy to discover
Harry and tyrrell killed it this week. Both awesome videos!
Thanks Iain for keeping alive these beautiful pieces of enginering of the past.
I'll post it every time, because it's true every time: every video is an absolute gem. I feel lucky to follow Iain's journey. I'm not sure a greater job than his exists in the world.
Another fantastic "day at school" for me - cannot wait for the warm-up episode. Thanks!
'Hope you enjoyed it?' That was an epic! Felt like an hour had passed and what an encore at the end! Excited how you're going to top the Italian Job too, very interesting! Thanks Ian and team x
Same here, cannot wait to see what it is that would top the Italian job!
Simply amazing!!!👍👋I never tire of watching videos about Miuras. Thank you Iain.
I find Carbs and mech/vacuum dizzy cars quite satisfying to work on. Arguably quite simple with a few key things to get correct. And once setup correctly they do give very good service. Even points work quite well, though electronic is a nice option. Pretty damn rare to break a spring though!
You should do a "loud pedal" segment on all your videos- just to see what they sound like. This one will be hard to top. Thanks Tyrrell
Every day is a school day watching Iain in action.
Back in the seventies I was lucky to work on Maserati engines. That had two sets of ignition points in the distributors both dwell angles had to be exactly right otherwise it was impossible to get all cylinders timed right. We had a machine that would spin the distributor and allow us to set the dwell angles running also to check the advance curve. On the engine in this video it would be possible with four sets of point to have four sets of three cylinders all with slightly different timings. Good to see and hear old technology running perfectly.
My absolute all time favourite automobile. The colour is amazing and the restoration and tuning is beyond amazing.
My heart longs for this car. Absolutely beautiful
The 'Testing the Loud Pedal' chapter was very well done. Filming and editing really spot on.
I could really watch this endlessly. What a master. Good job Iain! Can't wait to see the work proceed on Harry's Countach.
2:51 Priceless, just bloody brilliant!
The split cardboard box on the bench, this guy now has my full attention.
With a real distributor, not some nerd chip with a sine wave on a screen.
Will try the copper grease in my distributor to replace rubber grease I normally use.
This is a real how to.
Thanks.
Fantastic video once again Iain. Great sound footage of those carbs too. The video was all the better for the effort it took to capture.
Fantastic video Iain, that engine is certainly on song! All the best from ‘The Malton Motor Company’
How in the world does Iain learn all of these mechanical devices by heart. Humans are incredible 😊
18:43. The sound is now my ringtone
I thought the days of charming, quintessentially British engineering masterclass viewing had gone.
This is the perfect antidote. 👌
Best sound quality capturing Weber induction under load. Guessing you placed a microphone near trumpets. Demonstrates why induction sound trumps loud exhaust. Well done you have produced a sound recording like no other on the internet.
Loving the practical fault fixing, did I mention the sound of that engine ...
A pleasure to see a man in his element.
Takes me back to the carburetors & distributors I worked on in my early cars--though truth be told I enjoy the convenience of my current efi.
Great video. At 18:37 we see the carburettors and the absence of the whole rear panel. Must be a strange sight a Miura passing along without half the car!😊
Yes. I would have loved to have seen a wide shot of that!
I would have too. Not meaning to be mean, and I'm confident Mr. Tyrell knows what his doing, but I'm not sure the owner would have liked it too much, seeing his car outside with no protection over the carbs air inlets (not sure how you call these "cones") ?
@@jeanbalthazar8014 I thought it might be a legal issue - No covering around the wheels, no tail lights or number plates etc.
Must be illegal unless a garage can do stuff normal mortals can't...but I guess no one was looking eh? All good stuff
@@jeanbalthazar8014 They are called "trumpets"........
Love the way you broke it down so we could understand the problem...Loved seeing the little cam revolutions close up!
Despite being "a certain age" and being a reasonable weekend warrior, I never fail to learn a few new things every video and it's sensational seeing the cars I listed over as a young schoolboy. Iain you are truly a blend of theoretical car professor and meticulous craftsmanship. Always look forward to it and never disappointing.
Every day is really a school day, great summation.
Indeed, every day is a school day. Great sound from the V12.
The look of joy when he hits the peddle 😁 everytime makes me smile too.
Great fun as always to watch you tear into the innards of these classic exotics. Makes us poor punters green with envy! Keep 'em coming.
Seeing someone who works on these daily grinning like that when he opened the taps makes you realise just how special these cars are and just how much someone enjoys their work! Fantastic channel, fantastic descriptions, a joy to watch! Keep the video's coming!
Great that this kind of professionalism still exists! 2 of my 4 cars are with carburetors. Both are non stock configuration. I think tuning and understanding of carburetor function has become more and more rare knowledge these days.
Another fantastic video Iain! The near lost art of troubleshooting is well on display here. As Iain said, "school is always in".
A dream car this Miura, and again a fantastic technical story :)
Brilliant job tracing that little spring causing the ignition timing issue, such a small component having such a major influence on the smooth, efficient running of the engine!
I'm also a firm believer in warming up an engine, ever since my earlier motorbiking days.
My daily driver is a little Fiat Panda 4x4 Twinair the little 2 cylinder 875cc turbocharged engine, which I treat with the same warming up procedure as my performance bikes and even do a little cool down at the end of a fast hard run.
I never just shut off the engine when I'm finished, I just let it idle gently and let the turbo cool off etc
‘We don’t care about how much it’s worth, we only care about the open road and the loud pedal’ the last 4 minutes of this video made me cry.
Every days a school day, such pride and humility with no excuses.
Nice job on a lovely car.
To be fair to Joe Lucas, their distributors were OK, it was the 'Lucar' 1/4" push on connectors which were the cause of most of the electrical problems in British cars. In the 70s my friends with Fiats swore just as much at Magneti Marelli electrics particularly their alternators.
Thank you for your channel. I just found it. I am not a mechanic and do not work on cars but I appreciate a beautiful car and very much appreciate what it takes to keep them running. Thanks for posting and I enjoy learning about the cars so thank you for that as well. And just to add, that Lamborghini Miura is absolutely stunning.
