Lamborghini Miura - Tracing a running fault to a 17th century invention | Tyrrell's Classic Workshop

[@gondayi]

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 KZbin channel could ever manage, regardless of how big their budget is.

[@x.x..x.x]

You nailed it on all counts!

[@stanislavczebinski994]

One could argue Jay Leno has more interesting stuff in the background - but he has obviously different resources, so to speak.

[@hpkntnw]

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.

[@Kaptain13Gonzo]

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.

[@daniel2001]

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.

[@liverpoolscottish6430]

The Miura V12 symphony orchestra!! What a stunning machine on every level. Just EPIC. Many thanks for sharing Iain- fabulous!

[@stuarthicks2696]

I’ve seen those distributors for decades and never had ANY idea how they worked. This video gave me a glimpse. Thank you.

[@ronmoore5632]

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 !!!

[@C.Fecteau-AU-MJ13]

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.

[@blackbuttecruizr]

That smile when it accelerates... Priceless.

[@fteoOpty64]

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....

[@cryalowicki]

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.

[@kevinsnowdon9797]

I've another 20 years on you and totally agree with you. It's so simple when Mr T explained it.

[@grahamadamson4722]

Me too. I always find at least one nugget of new knowledge in Iain's videos. Another brilliant video from the master.

[@LOTPOR0402]

Thats because 20 years ago dizzys were a thing of the past in cars

[@andy-james-]

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.

[@PiDsPagePrototypes]

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.

[@Milen4u]

The engine shot without the rear clamshell is magnificent!

[@DavidHh1969]

18:43. The sound is now my ringtone

[@markevns9983]

When your engineer uses a paint brush you know you're on to a winner. Very educational Thank you.

[@raypace2885]

OMG! The end of the video was fantastic! The sound!!!!! Take care of yourself Iain, we need you.

[@colinashby3775]

That engine was the quietest engine I have heard in ages. It sounded like no lash at all. Smooth and quiet.

[@randomsurfer3963]

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..

[@MrPahankeisari]

I was worried about rear wheel throwing rocks to the carbs.

[@GTE_Channel]

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.

[@keithwelton]

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.

[@SerbanCMusca-ut8ny]

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.

[@enfield777]

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.

[@porscha901]

A case of muriaitus

[@_Daio_]

There is always a focus at any car garage.🤣🤣🤣

[@piccalillipit9211]

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.

[@johnsawyer2516]

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.

[@simonsackett]

I'd be more than happy to watch a detailed tune up from start to finish.

[@chrisg1592]

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.

[@RamSkirata]

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!

[@NLBassist]

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!

[@chrisroach9459]

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.

[@weofnjieofing]

Well done Iain! That sound was glorious! No greater symphony than a Classic Lamborghini V12 with quad triple choke Webers!

[@CubeCyclone]

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 !

[@mattsansom644]

[@Gorgonzola001]

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.

[@iain_tyrrell]

Our Videographer, Jonathan Whipp is excellent indeed! Thank you for those words have duly passed them on to him.

[@timcameron9023]

That's the most beautiful Miura I've ever seen, what a colour. Great video.

[@jonathangorrell9674]

One thing I like to use when rebuilding an old distributor is Krytox grease and oil. This stuff is made by Dupont and it is basically teflon. The key is in a distributor is there is lots of arcing going on and that produces ozone. Ozone is a powerful oxidizer that eats up normal hydrocarbon lubricants but has no effect on Krytox. So Krytox lubricants last much longer in this environment. Dupont makes a lot of different Krytox lubricants so you need to get the right on for your application. Krytox is used in lots of aviation application but you don't need to pay for the aviation certified products.

[@ianrobertsonRR1]

I am also a big fan of Krytox products, their range of products is massive with some very high tech stuff used in both the air & space industry. Costly ? Oh my yes but tailored to the exact requirements of the application. Off the shelf copper grease seems a very odd choice as it is basically an anti seize product not really aimed at lubrication which also has conductive properties which I would not use in a distributor environment.

[@Tuberuser187]

I think I just fell a little more in love with the Miura, how mechanical it is.

[@thomasmulhall4873]

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....

[@iainmacleod4007]

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.

[@oohmeconkers1968]

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 🙏

[@Mercmad]

and the whine of disgruntled owners queuing up to get a "quick" charge...

[@Slimboid]

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.

[@mosca3289]

That shot of the carbs and throttle linkage at work was awesome.

[@michaelsummerell8618]

"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.

No wonder you are the go-to guy for the marque Iain. Excellent work.

[@jeremyjs8863]

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.

[@gchampi2]

Ever heard the phrase "running Balls Out"? Well, the centrifugal steam governor was the origin of that phrase, as the bob-weights (balls) would rise & extend outward as the running speed of the engine they were governing rose. Balls Out was the maximum running speed of the engine, just before the governor activates & lets out any excess steam - hopefully preventing an overspeed incident which could lead to catastrophic damage to the engine & surroundings...

[@trevorleggo1777]

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.

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. 😂

[@paynebabes123]

My father walked in and thought I was watching Keir Starmer show off his car!! Great video as always.

[@NigelMarston]

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.

[@samuelezanuso981]

Thanks Iain for keeping alive these beautiful pieces of enginering of the past.

[@who-gives-a-toss_Bear]

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.

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 🙂

[@Milo_Minderbinder]

Exactly my findings, too. (...in over 40 ys)

[@ypaulyuk1]

I thought the same, the copper stuff is abrasive and will cause the parts to wear quickers

[@davey_projects2977]

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!

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
