Illustrated questions

#1

Considering I don't know the names of half the parts in my engine, and
considering that an image speaks a few hundred words, I decided to
illustrate my questions:

http://www.photocritic.org/hidden/mini/

fig 1:
What is the thing marked with "1"? It seems as though a duct should be
connected to the bottom of it, but I cannot find a loose duct anywhere in
the engine room of my car. I can't fathom what this thing is supposed to
do - it doesn't seem to filter or restrict the airflow in any way. Wouldn't
it make more sense to just take the whole thing off?

What is the little nozzle-type-thing marked "2"? It seems as if something
should be connected here as well, but once again, I can't find anything that
could viably be connected.

fig 2
1) What is this?
2) Why is it leaking oil?
3) How can I stop it from leaking oil?

fig 3
1) Is this the petrol overflow thing that is loose, or is it something else?
2) Should I try to reconnect it?

On the same picture, to the left of the image, is a black and white thing
affixed in the middle of some black tubing. Is this the fuel filter?

Sorry about all the questions, guys, but I'm a bit of a newbie.

Warm air valve. There should be a short aluminized fibre duct that sits
beneath it and connects to a tin shroud around the exhaust manifold.

There's a thermostatic flap valve inside it that allows hot air from
around the exhaust manifold to be mixed into the incoming air in cold
weather.

That makes sense. However, I live in England, and there is no such thing as
cold weather here (not compared to Norway, where I used to live for 15
years). so: Should I reconnect this thing, or should I just leave it the way
it is?

Quote:

Refit it with a smear of gasket compound on the threads.

Is this pressure switch below oil level in the engine? In other words, if I
take it off to put on this compound, will there be oil flying all over the
place?

Quote:

I can't see a fuel filter anywhere in your photos.

I would assume my car would have one, yes? where is it usually fitted in
minis, and should I replace it? I don't think it has been replaced the past
few years, unless it is part of a regular service.

Thanks so much for the answers so far!

.... and if I decide to not connect the duct, shoudl I just take the whole
device off? Would that improve airflow?

The duct is cheap enough. Just fit one and it will improve warm up times in
the winter ahead.

No, you won't get oil flying out. You will need to clean the threads of all
traces of oil before using jointing compound though.

Carb Mini's never had a fuel filter fitted as standard.

Oil pressure warning switch.

2) Why is it leaking oil?

Er.. Because it isn't sealed properly?

3) How can I stop it from leaking oil?

Refit it with a smear of gasket compound on the threads.

Personally i'd use a little bit of PTFE tape (plumbers use it) instead of
gasket sealant on that.

Ahh yes, but unlike almost any other newbie we've ever seen, you've got
the nouse to take some pics and show us what you're asking about!

You can remove whole thing (keep the airfilter box in place though,
just get rid of the metal bit) which will improce airflow slighty, if
you are looking to improve airflow though you should look at buying a
performance air filter although it will probably require that you
change the carb needle. Try searching these forums for "air filter" or
"stage 1" for more info on improving air flow.

You may find a little leaks out but you wont get covered.

I was under the impression that PTFE tape had a habit of breaking down
until long periods of high temperature?

I just did a highly scientific experiement:

PTFE tape held over a match seems to melt, but harden. I think that is a
good thing, really.

i would be saying that the unidentified hose in the bottom pic is a vaccum
hose
particuarly since you can see the fuel line just behind it,
my guess is that it goes to the brake booster (servo) if your a right hand
driver that is.
