Status - progress
Due to moving
house a couple of times - and having to build a new garage - the rebuild
process took a bit longer than stipulated. But since I had to
build one, I went for the "full house" and built one that could take some
car work in the future. A total of 75 insulated square meters,
including a separate 20 sqm for the daily driver.
Now the garage
is finished enough to be used, and the rebuild is on its way.
The electrical
system was not up to standard, so it's not going back in at all. I've
got a full set of fuse boxes, a big box with relays and lots of wire in
different colours and thicknesses. So I set out to build a new
electrical system from scratch:

A pair of nylon
panels for cutting bread on serves as basis. With holes and
brackets for fitting the relays and fuse boxes...
All wires for
the electricity central cut to length, crimped with the right connectors
and shrinking tube and labelled, ready for connecting:

The pedal box
is now finished. Just before Christmas 2006 I had the adjustable
frame in place, the new aluminium pedals hanging from their pivot points
and the cylinders for clutch and brake hooked up to their respective "cunifer"
(cupper/nickel/ferro) tubes. Including the stainless
steel-reinforced hoses at every end.

Fuel tank and
pump was fitted on the 13th of March 2007.

The cap is not nice, and even after a
machine polish it was too gruffy to look good. It was installed, but
will be changed on a later date.
The items
still to be finished on the spring of 2007 are:
Dashboard:

There is progress here though, and just the missing leather covers on
the A-posts stop the finishing at the moment.
Complete
interior...
Medio March the work started, with gluing the rubber foam to the posts
and ceiling, to make the backing layer for the inner ceiling and leather
covers.
Long time no
see
but have been busy with the car and not taking the time to write.
However now it's time for an update.
Finishing
The
summer and autumn of 2007 I was busy with fixing things around the
house, so not much progress on the Marcos. When the cold came the
urge came back and I managed to put hours in the garage again. And on
the 15th of May 2008 the licence plates are on.
The progress
was like this:
Rear lamps is
part of the electrical system, and as usual with this lady, they didn't
just drop into place. That is; they did, but didn't manage to keep water
out, so had to come back out for me to make new gaskets. The first set
was obviously made from too hard rubber, and that did not form a tight
seal. A visit to a local coachbuilder got me some softer rubber strips
and with a few hours cutting and gluing, the job was done and the lamps
back in.

Getting the
front lamps in was a bigger job. As shown in earlier pictures the car
was originally delivered with the square headlamps, and they were from a
British (RHD)Vauxhall Viva. Since they were rusty and had rusty
brackets they needed to be thrown away and replaced anyway. And
because I always liked the versions with twin round headlamps better
anyway, I went for that solution. When you want to change
something and have to decide which parts you want to use, it's always
wise to consider the spare situation. In other word, if something goes
wrong next year or in five years, will you manage to get spares for it
or will you have to start all over again. In this case I chose a safe
way and bought a set of double round headlamps - including the original
plastic brackets - from a BMW 3-series from the late 1980's, knowing
that BMW cater for their owners longer than most other manufacturers.
It took some
effort to close the square hole and make two smaller ones, before
painting the inside of the light bay black, and adapting the brackets to
fit. To connect the lamps I got original plugs from a breakers and
connected them to the wires that was already laid out. The metal
brackets that's holding the perspex covers in place were of course
rusted and useless as anything else than templates. So new ones were
made, from stainless steel this time.
The covers
themselves were reusable, but needed new metal brackets, and these were
aluminium parts bought from Marcos Heritage. The last bit was that
they needed a really good polish and a lick of paint on the rear area
before use.

The car came
with the original wheels - in need of refurbishment. So they were
sent for beadblasting and when I got them back I etch primed and painted
them in a greyish silver and had them shod with 185/70-13 Conti tyres.
One tyre seemed to be leaking so I went back to fix it, and this showed
out to be because the rim was a bit rough and let air through. A bit of
grinding on the inside fixed the problem.
The electric system was finished after a few weeks working, with pliers,
wires, fuse boxes etc. Then came a period of testing and rectifying
errors, checking one circuit at the time.
One of the
errors that showed up was not electrical. When the fuel pump in the boot
was tested I could hear it work, but it produced no petrol at the carb.
My mistake, as I had switched the tube out of and return to the tank
itself. Quickly remedied, only to find out that when the pump
actually sucked petrol from the tank rather than blowing air into it, it
tried to drown the boot floor in petrol!!! The pump was an
old one I had laying in the garage, but not used much. It showed
that the O-rings had dried out and cracked, and leaking petrol in great
amounts. New O-rings sorted this out in a day.
To make
everything as secure as possible I also installed a cut off switch
When the
electrics were found to be in order, the engine was trial started -
without the coil connected - and turned as is should and managed to
build up oil pressure as well. So the coil was connected and the
"starting started". With a dose of choke and pumping on the
accelerator pedal it caught, coughed, spit half metre flames from the
carb and then actually started!
Without any
knocking or "dangerous" / expensive sounds. Needed some tinkering
with the ignition timing and carb settings but promising. And no
visible leaks. Then some time after I stopped it I discovered a
puddle of oil on the floor. Just underneath the bottom of the bell
housing. Frustrating! I checked the engine and gear box to
see if there were signs of external leaks, like valve cover gaskets,
head gaskets, gear box draining and refill plug etc. but nothing.
It had to be either the rear crankshaft oil seal or the front gearbox
oil seal. At least the gearbox had to come out. But the low
height of the car made this difficult. It needed to be lifted
high, and since I don't have a lift a needed something else. After
a while I went out and bought a high lifting workshop jack that took it
up to 80 cm, and with a set of axle stands (for lorries ! - they were
certified to 6 tonnes each) with almost the same capacity I was in
business.

Gearbox
drained of oil, prop shaft disconnected at the rear and drawn out of the
'box. After the normal procedure I managed to ease it down on a special
bracket that I bought and installed on one of the small garage jacks.
The oil seal on the engine was dry as it should. Same story on the
gearbox. But the paper gasket between the front of the gearbox and
the bell housing seemed suspect, so it was replaced and silicone sealant
added to the equation. But when it was going back in it refused!
It seemed impossible to line up the gearbox and the incredibly heavy
bell housing with the engine while laying on my back underneath the car.
New tools had
to be bought. An "elephant". Which is the name used here in
Norway for a hydraulic engine hoist.

So out came
the engine as well, after coolant draining and disconnecting everything.
With both units on the gear box table it went well with connecting, and
I could soon lift the united engine and gear box back in again.

New connecting
and start up - and no leak.
Until after the engine was turned off!!
What was this?
It ran without leaking, but started to leak after it stopped? Were
the oil seals leaky anyway?
It had to come
out again....
I picked apart
the the gear box nose and found the seal to be dry/tight, so smeared new
silicone underneath the nose to make sure it didn't leak there, and took
off the flywheel to make a better check on the rear oil seal on the
engine. Dry and fine.
Engine and
'box back into the car, connected and started up. Dry. Until it
was stopped!!!
Engine and box
out again.
New
examination. When I took the box/bell housing off I registered that the
steel plate between the bell housing and engine was a bit bent at the
top and was rattling until the bell housing was bolted really tight onto
the engine. Inspecting these things revealed one thing: This steel
plate had more than one function. I hadn't discovered that it was
supposed to hold the oil seal for the balance axle in place. But
this looks like a small tin can with a rubber gasket along the edge and
for the steel plate to be able to do its job properly it needed 3 extra
bolts to hold it hard towards the back of the engine block, and these
were missing. A quick search revealed 3 unc bolts of the right
length in a box and the plate was tightened up properly.
The balance
axle can be seen on the right side of the crank oil seal housing on the
first picture. On the second the "tin can" is in place, and the 3 holes
for the steel plate securing bolts can be seen even spread around the
perimeter of the "can".

Engine goes
back together with the gear box and back into the car. After
connecting and starting it looks fine. And this time it stays fine also
after the engine is turned off. SUCCESS!

On the trip to
England to collect the Lotus Esprit I also bought a roll over bar for
the Marcos, as I've noticed how flimsy the roof is. After sanding
it down and painting it flat black it was installed just behind the
seats and with the supporting bars bolted to the chassis underneath the
back shelf.
Those rear
bolts will also serve as anchoring points for the safety harness later
on.
Then we had
the windows. Some time ago I decided to use plastic, to save
weight. After finding out that plastic was abusively expensive I
searched the net and came up with an address in China where I could buy
2 pieces of polycarbonate at 150 by 150 cm for a total of GBP 110,
delivered to my door and including the Norwegian VAT. So these
were already standing in the garage when I came to installing the
windows. The side screens and quarter lights were easily cut with
an electric pendulum saw. But the rear screen showed up to be a
bastard. The old one was disintegrated and could not serve properly as a
template, so I tried as well as I could to find the right shape.
And then used a heat gun to warm it up before bending it into shape,
weighing it down with 4 litre plastic cans of anti freeze.
But as it
showed up it was not easy to form the right radius for the bends.
And the shape of the opening also has very sharp curves so it was
difficult to make the gasket stay in place. After several attempts
I had to give up and order a perspex screen from England. But this
one time I was disappointed with my supplier. It arrived with courier
service 2 days before I was going on a 3 day trip with the car to a
meeting in Sweden, but my hopes of having it in in a few hours were
killed when I opened the package. It contained something that was
not ready for my car at all - vastly oversize and obviously meant for
the owner to cut to size, but since I got no warning about this - and
still didn't have any template - it came as a disappointment.
And then the
next shock: When I started to cut it with my pendulum saw the brittle
type of plastic splintered all over the floor! Nothing like the
polycarbonate I had worked with before. Luckily the fracture
didn't spread into the part of the screen that was going in the car, but
you can assume I was awake by now.
The trip to
Sweden went on without the rear screen and without the sunroof.

The process
further consisted of firstly of gluing the gasket onto the car with
sikaflex and the laying the screen on the gasket many times, marking it
with a felt pen and cutting a few millimetres at the time with a small
angle grinder with a very thin blade.
In the end I
managed - just. But the curves on this "original" screen are also
a bit out of place, so it does not fit as good as it should, and I had
to use more sikaflex to prevent leakage. I already decided that
next year I'll buy a new one, but not having it sent to Norway. Instead
I'll take the car to the supplier and have them fit it.
The only thing
still missing now is the sun roof. And that will come the coming
winter...
So a few
pictures of the car as it is - including the fancy aluminium door
mirrors I bought recently:
This is how
I'm going to use the car in the future, even if I already have plans for
changes within a couple of years. Just came back from England with a new
chassis for my next project, the Lotus Esprit. And when I was there I
couldn't resist buying a Vauxhall / Opel "red top" engine. Which means a
2 litre Cosworth headed twink 16 valver from a
Cavalier/Vectra/Kadett/Astra. Even without going inside these engines
it's possible to have 200 free revving horsepowers just by changing the
inlet / throttle bodies and exhaust manifold / system......
Update on
the 3rd of November:
I've been fed
up by the miserable fit and Sicaflexed rear screen for a while and
finaly managed to find a good - and luckily a bit old fashioned - car
glass company that promised to cure the thing if I left the car with
them for a couple of weeks.
It is
therefore in their custody at the moment, as I'm waiting to collect a
parcel at the post office. One that contains a print card
(motherboard) and several bags of small electronic components that must
be soldered on to the board. When that work is done the result
will (hopefully) "glow" into life as a MegaSquirt ECU. This winter
may lead to a much better sounding and running Ford V4 engine, and a
Marcos ready for the long trip to England and the 50th Marcos
anniversary in August.
Update on
the 22nd on May 2009
This became
some more time than anticipated, but here it comes:
The
glassmasters in Porsgrunn managed what I didn't and what the modern
quick fixers didn't. They got the rear screen in and almost looking like
a normal car rear window. And during the winter months I've been
learning how to solder. And managed to finish the Megasquirt ECU, tested
and passed.

So - after the
magic box was finished I spent some with working on the house, but
started to collect bits an pieces that's needed for the installation.
That's the throttle position sensor, crank sensor, oxygen sensor and
wide band lambda unit. And I'll just use the injectors from the old XE-engine
that's laying in the garage for now. Along with the fuel pump from
the Volvo 940 that I dismantled last autumn.
However to
make it more practical to use the car, I need to finish the sun roof
installation. And progress has been achieved on that front too:
Looking at how
it looked from the start gives me shivers:
But after
immeasurable hours of hard work, it starts to take shape:
And here is
the finished product. Not as if it came from a factory yesterday but
water tight and a good addition to an exciting car:
