but they are not at all happy with that. Both are without cylinders for various reasons that have not yet been explained. discovered, so one by one I'm going to bring them back to life, run them with twelve pots again and take them out on the road and make sure that they're doing what they're supposed to do, so let's take a look at the first one.

This is our first Italian v12. It's our old friend and chassis number 109. The fifth production Lamborghini ever built. It started life as a 350 GT, which from the model name. meant it was a three and a half liter v12 engine, which is what Giotto Bertolini originally intended the engine to be or designed it to be what Lamborghini engineers john palo de lara and paul Austin San Lee did was convert the parts of the Arrhenius design in a stronger engine. more Hardy unit because the three and a half liters were not incredibly reliable in service, the cylinder block was so-so in terms of strength, but it became apparent that in long-term service it really did not function properly without a bit of improvement , so what they did in 1966 was they brought out the four-liter engine, the 400 GT, and what happened was cars like this, when they went back to the factory service department, they told the customers look, we have this wonderful engine v12 that produces more power and is more reliable why don't you let us change the three and a half liter engine to the four liter and it will fit perfectly because it's like virtually and a lot of people did it and there are some.

The 350 GTS still run with their original three and a half liter engines, but many of those who returned to support say that ISA, the customer relations department of the factory actually has this modification and this car is one of them and the beauty is Because these cars are very light and this engine supposedly makes 305 brake horsepower or three to five, depending on who you talk to, that's a lot of power for a 3,000-pound car in the 1960s and many cars simply couldn't compete with it. The Tustin Martens weren't really developing that kind of power and I wouldn't dare say they were road Ferraris either.

The 275 gtb was being developed in a six-carb form, in its final iteration, around 270 brake horsepower and then when the four-cam 275 came out. In 1966-67 it was developing 300 brake horsepower, making it faster than the equivalent Ferrari and Aston Martin at the time. It was actually going like the wind with the four-liter engine, but unfortunately this car is not going like the wind at the moment. It has arrived before we start to dismantle the car to restore it. I just want to see how it actually drives on the road. I need to do a mechanical evaluation on it, so that's what we're doing at the moment we've excavated it. and I haven't even tried to get this car running properly yet, so the reason I suspect it fails is nothing more than bad spark plugs, the risk of stating the obvious if the spark doesn't jump between the electrodes in a spark. spark plug, you don't get spark, you don't get combustion, the cylinder is just very, very gasoline, with very horrible resistance to all the other cylinders that don't work the way you want them to, so let's just take a look at this.

I can usually get through it. Various tricks often bring the cylinders back to life by simply treating the engine in a certain way, so what we do is warm it up very gently by keeping it at about 1500 rpm so that the engine is spinning at a reasonable speed, not idling and not accelerating. . but we will get some heat through the engine and the spark plugs can start working again, they can self clean and sort themselves and you would be surprised how much this happens and I am very reluctant to just take the spark plugs as a blanket.

Take the engines out and put them back in because every time you do that you slightly wear the threads in the spark plug opening in the cylinder head and in fact on these engines the spark plugs are not easily accessible at all, it's just natural for people . Tendency and situations like this to think that the term taking the car out on the road and driving it will actually fix the type of missing cylinders, but it doesn't work like that, funny beast spark plugs, they need a little TLC. to bring them back to life again and if you put me to it, if you drive the engine too hard, load it too much or just let it idle, they won't come back to life, there has to be a certain technique. to this, that's what I'm going to use and you never know it might come back at twelve or we might be stuck with ones that don't work, but it's certainly the right thing to start with, so let's get started with it.

She warmed this up the first time this happened to the car for quite a while and just see how she responds, we've warmed up the engine and a couple of the cylinders have started knocking again so I guess it sounds good. I like that it's running at eight now, the fact that there's clicking and spitting coming out of the exhaust is a good sign because that means the spark plugs are trying to work inside the combustion chambers, so what I'm doing is working my Now around the carburetors I just adjust them very roughly so I can tell which cylinders are working and which are not and through this process and the engine has gotten even hotter, even more popping has come to light and the engine has stopped. spit and a few more cylinders have gone off so now we have up to ten cylinders working and I'm going through the engine and I've made sure that it's the two rear cylinders on the right side of the engine that are going backwards.

The car's breath isn't actually doing anything coincident because they were next to each other because they are getting fuel, so normally you would blame the carburetor if two cylinders are coming from the same thing, but it's not just pure coincidence. In this case I am removing the wire from the HT with chicken pliers as they are called plastic pliers because I don't want to get electrocuted when the HT shorts through me as a pro with the spark plug so I am removing the wires because If I remove them so the spark has to go somewhere else and then gently insert it into the top of the spark plug leaving a gap of a few millimeters, you can actually hear the cylinder running because the plug sits. put under pressure with a jumping spark rather than a point that is permanently connected, sounds strange but it works, so I did it with the last two wires on the right side and made sure that the other 10 cylinders are now working satisfactorily.

I'm pretty happy with that, but we won't know for sure until we fix these two, so I'm going to remove the two plugs and put a new thought plug in each of them. cylinders and that should really make a difference in the engine now and to do that I'm using this is a genuine 1970 Lamborghini factory spark plug cap and the reason I have to use this is because the wall goes down to the spark. The engine spark plug is extremely thin and there is almost no material in this and they are designed that way. I don't know why Lamborghinis made the spark plug holes so small, but they did, it's awfully hard to get these plugs out. but there we are comfortably, we have one of these, so now I'm going to remove those two plugs, replace them and let's see what difference it makes.

It is very, very important to feed them very carefully. Whittle, very light, you see. I'm using very light finger pressure to make sure the spark plug actually goes into the threads nice and nice and easy. We don't want cross-threaded spark plugs. Thank you very much again, just a very delicate touch. Let's try to light the spark plug. It's happy and there we go, we just cut the compression washer, don't tighten it too much and now we can put the cables back in and this should make a dramatic difference. We should have a Lamborghini v12 again and this engine is pretty hot and this cable doesn't want to continue which is not a good combination so let's see how it sounds now and now finally I'm just going to.

I over-adjusted the carburetor opening to include those two plugs and now I'm going to back this up to match the others and she should smooth out and slow down nicely, there we have it, that sounds better, now that we've had a good look around and we have brought things back to life. I'm going to just give the car a run and see how it performs on the road. The purpose of this is before we begin to massively disassemble the car to do body restoration, etc., and we prefer to know that mechanically it is in working order and capable of doing what it is.

It's supposed to and if it doesn't, if I find there are some faults, we can at least report them now on the worksheet and then fix them as we go, but let's see if the engines run on 12 cylinders again in the road. I hope we go. I can see right away that he's shooting really well from underneath, yeah he's pulling hard, so I think we're good. I don't know when it was last run on 12, but it hasn't been long. really to contaminate the spark plugs if they are in a hostile environment when they are started, bypassed and moved, engines are designed to be properly warmed up and then driven in this era and if they don't have that type of ideal conditions if they are started and stopped They usually start complaining pretty quickly, so we'll see how we get along.

I mean, I'm very happy with this she's pulling, she's smooth, slow, no kangaroo gas, so let's see how we get along. on the road oh she sounds very sweet yeah everything should be really very nice now the brake servos are sticking the brakes are sticking which is not great there are two brake servos and they are mounted on the front from the trunk, behind the rear. seat so I'm not going to try anymore the brakes are free enough now I can feel them yes she is spinning freely so before the brakes get hot or before I have to use them again we'll go back to the garage but we have proven it. that at least the engine is fine, it's pulling like a train, it's actually very smooth, I mean, it's pulling away from a thousand revs and she's as smooth as silk, so it's okay, girl in the box, you know what The brakes are free again not now. resistance, so we will take it to the

workshop

. oil pressures as they should be.

Italian oil pressure gauges are generally electrical, so we don't tend to believe everything we see with them, we check them with a separate mechanical pressure gauge. a shaft connect it to the engine and if I have any concerns about the oil pressure I obviously wouldn't drive it at all but the oil doesn't it sounds mechanically quiet the oil pressure is five kilograms per centimeter which is fine just we will shoot straight. again, but at least the engine doesn't really do them any good to be running on less than all its cylinders, the bores get washed out and things will wear out more quickly, so from that point of view I know we were on safe ground now yeah You need to start and drive the car before you can start making a list.

I can feel the steering wheel being off center, bitter play in the clutch pedal, things like that, so everything will be noted. and we figure it out and we can take the car apart and do whatever needs to be done. A few people have commented on this car in the previous videos and in the videos from Harry's garage. This is actually a Ferrari Daytona, it's a right-hand drive example. it's not a factory original Daytona Spyder, it was made in the mid 70's shortly after the car was new by transmission in California to very exacting standards, it's actually not that different from the original benephyrin job they did, They only made seven models with right-hand drive from the factory.

Daytona Spiders and a car in this color combination and in Sorel Dean Norma Talas otto with the beige interior, light tan interior, if my memory serves me correctly, it was a car of the exact color, one of the original seven was owned by Whose Pete Townsend, but this car. It's a top top as it is called, but it is still a beautiful example, it has been driven eight thousand six hundred miles from new alone and is documented and genuine, making it one of the lowest mileage dated owners in the world, as I mean, it started out as a coupe back then.

It was converted but the car still drives wonderfully well. We did some restoration work on this car about five or six years ago. It came in black with black and red leather. We changed the color to the original factory color, which is a beautiful Pininfarina. It was part of the original Pinna Farina color palette for period-date owners and we also had the interior reverted to the original Connolly color. The car is actually for sale so we've dug it up because we try to keep the cars in a state of readiness at all times and I like to take them out from time to time and just make sure they're up to par, really the brakes aren't pulling out all the diseasesusual, the suspension is not seized, the motors are behaving and this one is not, it's not very good actually, it sounds good, but it has no power at all, so I'll turn it on and see how it sounds before we continue.

At first it sounds, it sounds good, it's picking up reasonably well, it's soft enough but it still works. too slow, sounds laborious, I mean a Daytona should really crunch when you step on the accelerator, it should gulp air and accelerate quickly for such a big engine that has a fairly light flywheel meaning it spins very fast so it sounds like it is to me in a bank, a complete bank of six cylinders. I came across this before each bank has its own ignition system. They are basically two six-cylinder engines joined together. What is this engine? As with many v12 and ignition systems they are autonomous.

They are completely separate, apart from the power supply, that's all, that's all they have in common, everything else, the whole system, the low voltage system, as it's called the high voltage system, is all in two independent , so I'm just going to have a look at the start with the basics, look at the power supply, it won't be much because the last time this car ran it ran very well, but the problem is if we leave it like this, it will cause damage. I have unburned fuel going through the cylinders, the engine, which is not very good, the spark plugs go bad and stopped working, so I want to nip this in the bud now and see if we can get it working like it should again, so I'm going to start by simply looking at and inspecting the ignition systems on each bank.

Well, I have already dealt with this a little more and it is the ones on that bench that do not work, it is the six cylinders at a notable level in an engine that worries everyone. It's actually only half running, so I'm going to check the ignition system and see if I can get it to actually go into operation to ring. I'll start with the low voltage system first, like I said. I'm sure it's no big deal, it could be a rotor that's gone bad inside the distributor, it could be a bad power supply, but I'll start with the basics and see if we can get a result.

I have found the problem. and it's the low voltage side so it's the power feed to the distributor and over the years someone has put this rather nasty electrical connector in the wiring which actually intermittently caused it to break even plus manufacturing, so I'm going to change it. This connector here put something better on it, it's surprising because that connector could have been there for years, but all of a sudden it started working. Fortunately, I've run into this before over the years, so it's not something specific, but rather the benches falling over and causing this problem. so we'll change that and try it again and see if hopefully it hasn't affected any of the spark plugs and the damage caused them to stop working but step by step let's get it working again first.

It's a pretty neat repair so we'll see how the engine sounds now, hopefully, better if everything in life was as simple as that, the world would be a very happy place, we were lucky really, but there we are, we'll give it a try . the car runs now to make sure she's you know it's been a while since this car has been used so I want to make sure she's in tip top condition so let's go and listen to what the engine sounds like in action and in anger on the road. We have water temperature readings, she is almost fine, she is on par with the oil temperature and she activates from her seat.

The witches saw the ball that you can really expect during the day unless you take it down the highway or very, very high. speeds because there's almost 15 liters of engine oil in a Daytona and it's located in a remote location, it doesn't actually heat up that easily so we're about to open it up and see if under load it's still running, it's fine at 12 now is starting. Allah, let's see how he responds when I open the terms, yeah, okay, okay, still running great through all the harassment like a train, like a Daytona. If these cars had lungs that big, I mean, this was the fastest production car in the world. in the late sixties, early seventies and again we'll try again just because we can, oh yeah it's amazing the difference a properly running engine makes in a car - it makes it run or breaks it down driving a V12 that It runs on nine or ten cylinders. these companies, the whole car feels knocked down, it is obviously unhappy, the heart of the machine does not beat correctly and it makes a big difference that this is so, you know, the v12 runs on 12 cylinders and sometimes it is not easy for people detect it. whether they're running, one or two, it could be a v10 and still be very fast and still sound great, but you know, when it's on 12, there's nothing like this, this is calming down, the shock absorption is going down.

It's warming up, the brakes are warming up. a bit, this is: I'm going to do the litmus test now on a Ferrari v12 road engine from this era, they should do it if they are tuned for a percentage well below 1500 rpm if you step on the accelerator or something, no It is easy. do, of course, immortal traffic, that's 50, yes, that's great, very good, very good, well, he's gone to his old self, well that concludes another

classic

turell workshop.
