Engine bay tidy up, Part
1
Over the years I've done quite a lot of concours judging, and one of the first
things that struck me, was the scruffy condition of the engine compartment of
otherwise immaculate and highly polished cars. There were also those who went
to the opposite extreme of polishing and chrome plating everything in sight,
which is almost as likely to result in points deducted.
A well turned out engine
compartment is the one thing that shows real pride of ownership, and that the
owner is a true enthusiast and not just a poser. The aim should be to make everything
look as near as possible to how it looked when it left the factory. The ideal
time to make it all look good as new, is when you are doing a complete restoration,
but even if you are not, it is still possible to produce a prize winner, for
a little cost and effort. Here is how I would go about it.
First thing to do is make
things easy for yourself and remove the bonnet, this will come in for some treatment
in due course but for the time being wrap it up and put it somewhere safe.
Ideally at this stage you
should take the engine out but unless it needs a rebuild you will probably want
to leave it in. Most old cars have plenty of room around the engine so this
should not present a problem.
Before you go any further
take a load of pictures from every angle so you can see where everything goes,
and to show everybody what it used to look like when you have finished. Next
job is to remove all the ancillaries off the engine, including inlet and exhaust
manifolds, you will be surprised how much muck is behind them. I'm sorry but
the radiator will have to come off as well, and all the electrical stuff like
relays and regulators. Don't forget to label the wires so you know where to
put them back. Keep all the nuts bolts and screws in a box, you can either get
them zinc plated or better still use them to make a list of what's needed and
order new ones, making sure you get the correct threads. If you decide to get
your stuff re plated, consider taking all the screws out of the carburetor and
other ancillaries and getting them plated also. This means a lot of dismantling
all at once and a lot of things lying around in boxes, so a few quid spent on
plastic storage bins is a good investment.
Most Fifties and Sixties
cars have electrical relays enclosed in galvanised metal canisters, and these
can be made to look good very easily. Dismantle them by prising back the metal
tabs which retain the innards, then carefully put these to one side, together
with the cork gasket which keeps out the elements. The canisters can then be
plated with all the other stuff.
Make a list of everything
you are getting plated, in case anything gets lost.
You now need to do some shopping
for the following:-
- A big can of degreaser
such as Gunk or Jizer to clean off the engine.
- A bottle of white spirits
or thinners to clean off everything that needs painting.
- Some paint for the engine,
make sure you get the correct colour, they are all available so there are
no excuses. If your engine was black originally, use Black Smoothrite it's
as good as anything.
- An aerosol of black Japlac
(from Focus Do-it-all) for the black shiny bits.
- A large roll of black
loom tape to tidy up your wiring loom.
- Gaskets for manifolds,
rocker box and carb.
- An aerosol can of black
VHT paint for the exhaust manifold, or you can use Pot Black which is OK but
you have to brush it on so the finish isn't as good. You MUST get the manifold
sandblasted before attempting to paint it or you will be wasting your time
If the paint work on the surrounding areas won't clean up you will have to
repaint it so some aerosol cans of the correct colour will be needed, and
some appropriate primer. You may want to consider overhauling a few things
while you've got them off, in which case you need the necessary overhaul kits.
Right I'll leave you to
get stuck in to cleaning the engine off, and getting all the necessary, while
I put the kettle on and we will move on to the next stage next time.

A scruffy engine bay like
this can easily be transformed into a prize winner.
