Well I used to drive a 77 Nova with the 250 L6 (at least until the
lady in the 240Z shortened it by a foot and a half).  This car
would get in the mid teens city and actually about 20 MPG on long 
highway runs.  The carb on the bloody thing had always been a bit 
screwed.  I had assumed that it was a combination of early generation
pollution control stuff and a flaky electric choke.  I was never able
to optimize the mileage, I tried to optimize to keep it from stalling. 
Even so I got very good at the Nova accelerator oscillation routine. 
One bit of advice, if it stalls on you on the road hit your emergency
flashers FIRST before you start you restart routine, even if you are 
well off the road.  My Nova is no more because 240Z did 35 mph in to 
the back bumper while I was at the side of the road.   That was back
in january and my leg still has the remainents of a nasty hematoma
where my shin decelerated against the steel dashboard as the Nova 
was pushed into a fence.

	"they mentioned they use GM oil"

Yeah, sure.  The place I bought my Chevy from uses Kendall "two fingers" oil.
Not that I would ever go there for an oil change, or even the time of day.
This is the place where I went for some warranty work one time and they stuck
the wrong key in the door and broke the lock.  They did the work and then just
parked it outside without saying anything.  I discovered it when I tried to
open the door using the right key.  Then they tried to tell me it was that way
when I brought it in.  (Classic dealer excuse no. 237).  They finally agreed to
fix it free, but to this day that lock isn't as smooth as it used to be.  Of
course, this dealer went out of business two years ago, showing that there is
some justice in the world after all.

Didn't we just have a long discussion about what's the "best" oil?  I think the
consensus was that it didn't matter a whole lot as long as you change it
regularly and stick to a known brand name.  I use whatever's on sale at K-Mart
and change it every 3K miles.  Lately, that's been Valvoline or Havoline.  A
local car place had Castrol on sale a while back.

Headers are exhaust pipes - often pipes quite literally, as most stock
exhausts are iron castings - which are "tuned" by (a) increasing the diameter
and (b) varying the length of the pipes. The former allows a freer flow of
exhaust; the latter "times" the pulse from the exhaust strokes of the cylinders
so that they don't conflict with one another. The goal is to reduce back
pressure on the cylinder.

There's also usually a sprung-weight savings.

The "turbo" is short-hand for "TurboHydramatic" the GM brand-name for
their automatic transmissions.

The 'clutch fan' is a 'fan clutch'. The fan clutch is a gizmo that allows
your engine fan to free-wheel at certain engine RPM's. That way there's less
air-resistance from the fan at times that the fan speed doesn't have a marked
improvement on engine cooling, resulting in less drag and more net horsepower
delivered to the crankshaft...

Actually, a well designed header does a bit better than that.  The exhaust
is emitted in pulses and if the header is tuned properly, the low pressure
behind the pressure peaks can be timed to "scavenge"  or suck the exhaust
gas from the other cylinders, which also has the effect of drawing a better
air/fuel charge through the intake side.  Good headers are well worth the
price, but tend to be noisier and more leakage prone than the stock manifold.
I think the sound is kinda cool, but that's definitely a subjective matter.
Legality may be a problem in some states...

I believe the '79 VW would have used Bosch's CIS injection system, with the

airsteam.  If this is the case, cleaning would involve forcing the solvent
through the injectors at pressure, and little more.  One thing to

would be from SAABs, but I would bet serious $$ that they are the

Just my humble opinion, but

- do you need the added braking power?
- is the caliper mounting the same in both cars?
- are the spindles identical (PLEASE tell me you'll put in new wheel bearings,
  races, and turn the rotors once on the car!)
- bigger brakes = more unsprung weight = increased rolling resistance = reduced
  gas mileage

Hi auto-netters/lovers,

I've got a Nissan Micra 1984 automatic and I'd like to know
if there is/are any technical/reference book about it.
Indeed, I've asked a Nissan dealer here in Paris and
they told there is one but it cost 700 francs, around 140$!

I think the Micra is not available in the US, may be too small,
or not safe enough dunno, but you can find it in Europe,
especially in UK.

So if any one can help me in that, It'd be great, 'coz
I'm having minor problems now, such as transmission belt broken,
but can expect the worst 8-(!

The Ultra-drive is supposedly fixed on 92 models, all prior years have 
problems. I've a 1990 Grand Caravan, a month ago mine fail totally at
44,000 mi. The perform the repair and in essense an upgrade to 
'92 level "kit" upgrade. The transmission shifts smoother than alot of
other Chrysler and non-Chrysler trannys. There goes my excuse to buy
a new Caravan :-)

It is a series of fixes inside the transmission relating the the computer
and stuff. The only mod not performed is the change in torque convertor
which relates to slow speed smoothness.

Hopefully, the previous owner has paperwork to show the work was performed.
You can't tell otherwise. An experience owner of a bad transmission 
that was repaired can tell after driving a while. 

My complaint is that it took a complete failure before the dealer agreed
to perform the standard upgrade. Basically, wait until it fails completely.

When cars were young, in the days of your grandparents before there
ever was a "hard top" model, there were touring cars. I have never
heard that the designation GT only applied to hardtop vehicles.

I used J-B Weld about two years ago to repair the carburetor on my '84
Honda Accord.  I had to take off the carburetor in order to replace the
insulator (base plate), which was leaking on the bottom.

One of the five nuts holding the carb to the base plate was frozen.  In
the end, I had to remove the base plate with the carb still attached,
then drill holes in the offending nut until it was weakened enough to
come off using a needle-nosed Vise-Grip.  (The stud which the nut went
onto was part of the base plate, which I had to replace anyway, so it
didn't matter that it was ruined by the drilling.)

Anyway, in the process of removing the nut, I broke off one of the vac-
uum hose fittings in the back of the carb.

A friend recommended J-B Weld.  I got some, then stood the carb up on
end with the broken fitting pointing up.  I took a small stick (actu-
ally, it was the little red plastic straw from a can of WD-40), stuck
it down the hole, and threaded the broken-off metal tube over it.  I
mixed some J-B Weld and applied it all around the broken area, then let
it sit for a day or so until it was thoroughly cured.

The car is still running fine, two years later.

Yes, I know I could probably have dug out the part of the metal tube
that was left in the carb, then replaced it with a new tube -- but the
J-B Weld fix definitely worked.

I own an '85 900 turbo, which has the standard rectangular U.S.

take the entire space occupied by the rectangular headlamp and the
trimpiece/parking light around it.  I've heard that the dealer price
on these is in the ballpark of $200/each, which is too rich for my

    My recollection of the Car&Driver article on the XR4Ti when it was first

four was more powerful than the 2.8 six in the European version. Maybe the
Pinto engine in the right tune isn't so bad after all. At least it has an
overhead cam!  Add a big exhaust pipe, an intercooler, and some induction mods
and you're right up to 225hp. 
 Besides, you can buy good used XR4Ti's over here for next to nothing! so nyeah
