Lubo, a very good morning.
Apologies for delay in replying, this email address is in work hence I
don't pick up any messages until Monday morning.
Re Alternator - yes the unit may have been supplied on an exchange
basis - you will have to check. There seems to have been little in the
way of technical diagnosis prior to changing it. Simply connecting a
voltmeter across the output terminals seems a fundamentally obvious
position to start from. Changing major - expensive components should
never be the first option.
With the motor running check the battery voltage engine warm, about
13.5 volts, start switching on the various electrical units, the rear
window heater and fan are big current consumers, provided the alternator
is fine the battery voltage should not drop. More loading causes extra
coils in the alternator to provide power to compensate.
Your dealer cannot hide behind the attitude - not sold here. I
appreciate they have no experience of 80s and hence were unaware of the
air screen pre heater and its high current draw. My response to that is
- they should do some research with Toyota or decline to work on the
vehicle due to lack of knowledge. I would add that there are many common
test procedures when fault finding that any competent mechanic /
technician would employ irrespective of his knowledge of the vehicle he
is working on. To be specific for your case - as above - use of a
voltmeter.
As a further example if there was a problem with the cooling system
would they dive in and change the radiator or would they have used a
coolant system tester?
The 80 has a diagnostic port - I do not know if the chaging circuit
can be tested through this - possibly someone may educate us.
Ticking,
The valves you are speaking of, I assume these must be the EGR -
Exhaust Gas Recirculation - valves. Two cast iron units located on the
upper part of the exhaust manifold. I have them on my '97 model. I don't
think they tick. I would add that in certain circumstances my engine has
always, in the 3 and half years I have owned it, made some strange very
occasional ticking noises. These have not changed in volume, frequency
or regularity. I have never been able to determine their cause, the
noises have not got any worse. The vehicle runs very well with plenty of
get up and go and is quiet, other than the exhaust - Julian !!
I am perfectly happy for you you to pass these e-mails on to your
Toyota dealer. They should know how the basic components in a vehicle
work - these things are common to all vehicles - they should test before
changing.
My verdict - and I'm not being sarcastic - more training required.
You also have learnt an expensive lesson.

Hi Gareth
thank you for the answer-it's on its way to 'Toyota' already :)
got answer form the chief mechanic agreed to look at it when i come
with the car 08.08.06-I get an appointment there for the
ticking. they mean it is EGR -Exhaust Gas Recirculation - valves. Now
as your email is on its way they might reconsider
their point of view ?????
cheers
