Lamborghini V12 engine rebuild part 5. Putting it all back together again.

Lamborghini V12 engine rebuild part 5. Putting it all back together again.
welcome to a new Harry's garage video and as you can see we're

back

in in terral's workshop because this is

part

5 of the

Lamborghini

Espada

engine

rebuild

and there's been a slight pause I look

back

and we did the last video sort of beginning of December and what we've been waiting for were the Pistons to arrive they've actually were being made in America and they're made exactly to size for the car they're not on the shelf items but they're

back

in the
lamborghini v12 engine rebuild part 5 putting it all back together again
workshop and that means we're at the stage where we can

rebuild

the

engine

so I've come up have a quick look at what else is going on in this workshop there's always good stuff around this I see the mirrors got stripped as well all the

engine

s come a

part

on that as well but what I'm really interested is going join Marcus and Ian or at the bench and what we're gonna do is just start the

engine

rebuild

in this video so I can't wait to see it how's this action stations
by the look of it yes yes yes

again

Ian and you yeah thank you Marcus you're

putting

some grotty stuff on the bearings already aren't you oh yeah go yeah just wait the Bethany that's a little graphite paste I find you you knew they live yeah oh I don't graph that yeah and what's it do you that's just on the bearings just going on the bearings before you actually input the crank into place it's it's it's very busy stuff really because it sticks to everything
like glue yes and but as soon as the oil gets round and sort of it just washes off in term what's the word dissolves into the

engine

oil right because sometimes I've seen people squirt oil on all the berries before

putting

the crank here this is I see the better yeah yeah because that well until the old pressure builds up that will carry on so working so it's it's all about that starter I ought to see these Pistons how believe they're so lovely and they've got a little
trick bits on here yes they've got this is Tiff's lon you were saying it is a little black skirts yeah it's well it's all it's it's a friction reducer so the yeah that's that's it's a Teflon spray Don coating I've never seen that before yeah it's well a lot of Pistons manufacturers put bits on black patches on their pit rice and they quite often paint believe it or not right it's not made better these this is the real deal these have been made by a
company in California yeah we were I approached the British companies companies in the US they were about the friendliest and renewable resistant manufacturer so I've gone with them and they are yeah same compression is standard right they're forged so they will they're built to go to high revs and this is all just a really wide for people haven't seen some of the other videos one of my requests is we're gonna

rebuild

the

engine

I wanted it sort of a top spec I've always
been a bit jealous of the Miura that was higher revving than the Espada so how I'm not going to be using 8,000 rpm all the time but this

engine

basically should is capable so yeah you've investigated how we could do it and one of the things we had to do was upgrade the quality of the Pistons from cast to for just correct way around yes yeah so that's done so these are forged and they are at mr. too nice to put inside the apparently they had ordered 13 so I could have one piston for
the desk just got thirty twelve and these and these aren't on the Shelf item are there's a lot these are specially made specially made so you could say way that yes they're made to your size you'd say what size you want them yeah that's the case that's right well that the standard bore is 82 millimeters right and we've actually gone for eighty two point five to make sure we actually board beyond any miss Shay firmness in the bores so as I mentioned to you previously
yeah the extra half a millimeter diameter gives us about 40 CC 40 CC I mean you're really noticed yeah I don't know yeah but these these should be that these will drag a lot less up and down the cylinders than the original piston as well so you think there's a bit of a horsepower gain from having the tears I dunno yeah yeah I mean on a on a v12 that revs to sort of 7,000 the frictional losses and pumping losses can be a hundred two hundred and fifty brake horsepower over snip yep
absolutely so yeah we don't know what the gain is but it's yeah yeah it doesn't get all of that

back

does it it just reduces it a little yeah every little helps yeah and then you've done the balls on this to match this so you waited for the pistons arrived measure the ball oh sorry the pistons is that right so that is exactly right yeah yeah I mean the piston manufactures have given us a very precise specifications to work from and I chose the material so this is not NASCAR spec
aluminium riot this is somewhere in between rice around her in NASCAR no no I exactly yeah good well sorry it's time to break the news to you know the sir yet they've been they are bespoke so they've been made the actual skirt clearances two and a half thousands of an inch we've actually made it just a tiny bit more but modern pistons have a much smaller clearance than all the pista - because they try the material is more high-tech and it doesn't it doesn't sort of
expanding contras and changed quite a cyclic rise okay well so the first stage in the

engine

rebuild

then is that crank going into there then exactly but in Bolton it all up yeah I'd better let you crack on there I would suggest this a bit with that and then we can get on to stage two and I'm gonna be here long enough I think see a few Pistons getting well let's hope so yeah so we've blown everything out yeah it's been polished yeah we've put the new shell bearings in as
lamborghini v12 engine rebuild part 5 putting it all back together again
you call them and you're out yeah it's really aura but you know that's fine like me I've got this other one here yeah well I'll let you crack on with that because I'm not getting involved until what this bits rocket otherwise we're gonna crank or pond rod poking out of here oh so y'all that was the one that met cassidy okay yeah like I'm in a delivery room I shouldn't buy needs to go up at your end a bit much it's it yeah you still got the way yeah
yeah looking good right this ain't sure there we go okay lovely face on the web's isn't it on the bearings yes this is normally out in fresh air on other

engine

s than those of the crank that is actually incessantly inside the crank case here how much do you think a crank is worth for one of these and if you were to buy one from

Lamborghini

now yes about 14,000 pounds well that's a tease pass through those 17,000 yes a little bit postage automated yes I think there's certainly
an Italian president over personally yes so next stage is the claps then main bearing caps of which there are 677 enormous bearings then at the end of the cranks there's their bigger area yes a very different not not diameter wise but width wise yeah and you have to sort of order them as individual

part

s strangely enough because they've all got individual

part

numbers and we huh first were in place now and what are you doing about the the nuts but we'll go

back

the ones that have
been used before yes but that on the piste well we'll get to the business a minute but so these have been reused to the threads you haven't had to replace those is what we're tightening them you know yeah and even though manufacturers give you talks and things it's actually about feel it's how the have a thread than the nuts are going on and so for example I started my working life in a rolls-royce and Bentley workshop Anna Rosa listen Bentley didn't give torque figures
on

engine

s so it was actually about feel and about seat-of-the-pants the way if you if you if you brought a torque wrench into the workshop it was probably an instantly psychoville Afeni service because it's all about how the thread actually it's all about the feel and how the thread actually responds if you can feel weakness in it as you tighten it first you finished I can tell these are going on beautifully these knots yeah normally for thread or nuts damaged you talk hon type you
can't hand those read them no okay right tight on their tiny washes are they they are very thin they're delivered of

Lamborghini

these washers they use them on the cylinder head nuts as well they are super super thin what I really want to do is make sure that the cranks just feels nice when all right any capture sort their eyes see see how tight it is yeah or not hopefully without being too too loose it's all you know if it feels right it is right right okay so then you've got
those funny things it's end float the crank can sort of move this way in there and you have to get those it will that's the thrust washers are in just washes us yeah and we've already checked the end float actually and it is I guess it's as it should be so in that respect we're we're all right desert so every time you press the clutch pedals there it pushes

again

st the Craig's a crank has to hold the pressure of the clothes and unmodern cars a lot of cars these days
yeah well I say Morgan actually my adapt my idea of modern before electrics etcetera here you can't enough to push the clutch down before you start the

engine

I I do that I always think it this keeps the start emotive not having eternal to give saxy is that right but a lot of cars have an electrical switch on them how they do that as well and you can't start the

engine

last year touchdown yeah I always think to myself they must wreak havoc with the thrust bearings so would you start an
old

engine

with the press in the clutch I always do personally yeah I always think that starter motors having to turn all the other gear comes in the gearbox makes estimate but I agree yes like can't see on camera but they're little studs either side of the big stunts so is that just a you had it yeah so famous for bolt mains right which are beloved of American hot rodders and things and these have them as standard so yeah it's it just stops everything moving right it much because
because it's aluminium and not cast-iron yeah just you know precautionary stuff as you say this

engine

is actually a 4-1

engine

basically in it when he designed it I think it's the one it was but that's why I started life as a three liter three and a half liter I couldn't say for sure possibly it started life even as a three liter because I cut my cotton and what the capacity limit was in the early 60s but certainly if it sort of after 18 months it went up to four you know their
own keeper does Rena but they completely re-

engine

ered the block it's it's not the same block I always think going

back

to original

Lamborghini

early days the 350gt was a heavier car in the Miura was much lighter so I guess that might be the reason for leaders I don't know and yeah I suppose Ferrari was going for later as well yes it's the three and a half litre block wasn't actually up to been a racing car has a different sort of remit to a road car doesn't yet as long
lamborghini v12 engine rebuild part 5 putting it all back together again
as it lasts for 24 hours maximum or whatever is it a road car it's it's late leader hard life don't leave out cars there for a long period we're gonna try and turn right now yeah look at I'm gonna have to look at that just oh that's lovely yes I mean there's a bit us it's an ease of movement so I'm gonna say sticks is not sticks and it's just there is it's it's all bolted

together

you can feel that those berries are tights aren't they yeah
we're not gonna hook them down yet those are nice but no it's lovely isn't it sorry yes it's not a toy that's an

engine

how do I explain that oh yeah move swiftly on oh dear yes is taking longer than I expected it's the obsessive in me yeah this is normally reserved for cylinder head tightening but they all feel absolutely beautiful tightened up really nicely okay now still turns oh look at that yeah I love it when a plan comes

together

yeah like it's meant to be in
there yeah guy he's just seeing that spinning at 7000 rpm I just yeah it doesn't compute does it Wow I mean 6000 reps which of course almost every

engine

turbo half-decent

engine

does problems diesels and the Pistons are flying up inside the balls a hundred times a second this isn't it right so the crank is now in and spinning just lovely what's next stage then we'll start

putting

the Pistons and rods assemblies in so that we've put the Pistons on the rods with the new
gutter pens the new wrist pins as the Americans call them guys yeah and if they

again

they felt really really it felt really nice all the clearances you know we've checked and double-checked all the clearances are great and the connecting rods have been away to be Iraq tested to be a non-destructive texture tested they're all fine so we can put it all

back

together

with some new began bearing shells right so you how you do because it blocks the wrong way around these go in from the at
saw so we turn we do turn the block out when you turn the book over but then you got to get to the Academy and that's the tricky bit precise so we're gonna watch some magic right there you got an awkward thing called piston rings and all sources oh yes piston ring compressor just put loads of why we love these with oil around here when you suspect the pistons that what happens about the Rings they just go as standard rings do they well the ring the Rings are designed for HTTP mill bores
and especially made for these persons are but they're not the original modern piston rings in order to reduce frictional losses have a one millimeter top piston ring this much thinner that tetr-a one point 5 we see original bore ghost better

Lamborghini

in the nineteen seventies and sixties right and then there's a scraper at the bottom exactly which is three millimeters and the original

Lamborghini

one was four and a half that on there which is number one that one actually one nearest
the front right wonders oh because they're slightly stick yes exactly most v12 czar like that so that the rods can be next two years I'm eased on the yeah yes so we're gonna knock this in we have to watch the theater so we got loads yeah let's carefully do that okay hey presto you say it goes through that colors that lovely wrestled if anybody's wrestle an

engine

rebuild

without one of those piston ring compressors I would buy one now I've never had it as easy as that to
make sure that shells the right way around it's number two number isn't it exactly when it separates s William but you just want everything to be chapped

Lamborghini

actually put a little can remember from taking it a

part

they could little split pins through thee yes is the hole in the big and bolt and the split pin goes at least need nip up to the nearest available slot us 44 pounds to begins just spin this round so that you can actually get a sit there we go see there the numbers
there's number two piston and con rods and that's what we're matching up those numbers they're lovely EPS done in 1969 see ya right I'm gonna leave Marcus just to put a few more Pistons in there and con rods because I just wanna have a look at this S

part

acus has been some work going on on that over the last few weeks a little bit tidier than when I last saw it yeah come belaboring can we borrow you for a minute there was layer upon layer of yeah and zus coating wasn't
there sort of really thick under seal like bitumen based yeah the old-fashioned stuff you've taken quite a lot of that off but it has been doing a good job viola predict that the only absolutely yeah I know there's no corrosion that's all that's great it's astonishing job just a case of giving it all a good scrub really would deter JIT - yeah loyal and wrote dirt off I suppose gonna be great when it says 400 GT Espada you can see very pleased if enough fur yeah yeah it's
definitely add

Lamborghini

yeah yeah which is really good it's very pleasing that it's all in such good condition because yeah these are actually enclosed but this is called the pontoon timeframe if it's a repetitive basic layout yeah and these these because they're enclosed box actions that like all enclosed box sections of Steel of this era either they're metal on the inside because they didn't paint them and be once that once the divinity from the air gets in through a
tool a small pinhole or something it can't get out and they just sweat and the what moisture manifests itself is rust that's the big enemy of cars of this era but these are absolutely lovely father yeah yeah and he lose the ritual thank you it doesn't look original and now it's it's very solid good so yeah basically you clean it all off spend a couple of days in there with a scraper getting it all nice and clean on the roof so you've been trying out some different sort of
lasting thicknesses and stuff isn't yeah we know dilemma here isn't it was exactly the black roof had one advantage where you'll explain its how you glue it in place isn't it well it's the black roof was was largely opaque yeah and so all this lovely gooey sealant that was around the outside here you couldn't actually see it because it was so dark the trick with

putting

am a sort of more clear roofing is going to be to not have this horrible sploagie mess that you can see
right outside so we we means the various options a lot of modern car wind screens all car windows have a sort of black border to them yes get rid of things because they're all bonded in it not not use rubbing rubber seals anymore and it sort of disguises all this the sealant they use yeah but we can't really do that with the plastic because we got to be cared for one thing I'm conscious office but it doesn't blow off at my speed yeah well that was the first test I did when I test
drove the car was just to go just over 71 miles now just to see what the roof did the high-speed how do you think yeah I've been you know after 120 hours this wasn't a nice car you know that

part

s the world I mean the roof was absolutely fine but I think the possible solution is looking at the surround the windscreen has this stain steel while here it is and maybe we do something like that around here so it actually looks more fitted so we say yeah that would that would be a really
really good solution it really would I think that might be the way to go it wouldn't look out of place nothing and it would save a lot of it a lot of problems ya know a little place you'd like that still spins and it's got two Pistons in because I don't always do that always some edges are really tight huh yeah yes even must be vetted Syrian announcer yeah okay as we go along I'll get tighter the tens ago we forget how far up into the cylinder have they come isn't it
that is really quite a lot out isn't it car oh yeah yeah well there's the valve timing is critical because their valves are literally two or three millimeters away from the piston crowns if everything set up properly when you know they just narrowly miss each other that really is right out if you get the valve timing a tooth or two out on the chain it's bang yeah you get a very loud clattering noise yes yes that's not the thing that is actually it because you couldn't we
could move those companies absolutely yeah well it Bob aren't they yep that's great so next stage pisses overseeing bolt up and then you've got build the heads up and yes sir we're waiting for the valve springs to arrive still that says I finally arrived at a formula with the valve spring manufacturers yeah which is essentially within percentage of what the Miura spring started eyes sorry and yeah so that's the other main cause for concern for it if the

engine

s can read a bit
more I oh yes it's

part

of Al's floater just over 7,000 serious SVM with the standard springs and then the fact was they'd actually weakened over time exactly so they needed to be replaced and we've just made in that little bit strong exactly terrific well that's been great see the

engine

you know start going

back

together

how many months is that's about four or five months isn't it yeah that's something like that to get all the

part

s

together

but it's just
magic just I just think it's one of the most beautiful

engine

s and to see it sort of being reborn it's just great thank you very much okay yeah there we go so I hope you enjoyed this video as well I hope you have because there'll be some more videos coming along very soon you
