If you are generally hard on your brakes, this is probably normal.

The problem with rubbing compound is that it is very easy to take off your
paint along with the wax.  Even if you are careful, you might wind up with
swirl marks on the car.

Adding a steering stabilizer will help, but if this has the old style
jeep steering (from mid 40's) it always has a lot of slop. I think they
updated it in the Mid 70's. A Sawginaw steering conversion is the correct
solution for the old system (just what Jeep did). Advanced Adapters sells a 
kit for this (and there are other outfits selling clones for 2/3's their price).

Good Luck!

You should cover the fluid reservior loosly with some plastic wrap.  If you don't, 
brake fluid may squirt out.  If the fluid remains on any painted surface, it will 
remove the paint.  Otherwise, C-clamps are the way to go . . .

Subject: How to fix moulding on Honda Prelude
Organization: Vertex Pharmaceuticals, Inc.
Date: Mon, 28 Sep 1992 20:50:42 GMT

I have a 1984 Honda Prelude. Recently, some kind soul managed to
slam their door into the side moulding. They hit it hard enough to break
one of the plastic brackets that hold the moulding on, so now it's
sticking out (and the door can't be opened without precariously bending
the moulding). I've purchased a new support bracket from the dealer,
but it isn't completely obvious to me how to install it...

I would guess that the moulding slides off, either by pushing it forward
or reverse (relative to the car). Is this correct? Or does it simply
pull off (which would seem to mean that all the brackets would be
in danger of breaking when I remove it)?

Thanks...

Only if it's a bypass oil filter and a hole probably wouldn't drop it
drop the pressure that much since your only running around 10% bypass
oil throught the filter.  If your refering to a typical auto full flow
filter, a hole in a full flow oil filter will show an increase in oil
pressure because of less restriction in the oil circuit.  Remember.
it's in series, and the oil pressure sensor should be AFTER
the oil filter/cooler.

Neither of my cars has an extra injector for fule for cold starts.  The Mazda
EGI in my RX-7 has one for 90% antifreeze solution, but that's a different
story.  The Bosch L-Jetronic systems mainly use air flow to regulate
the fule flow.  I beileve that the L Jetronic system is the one that I
was reading about with the aux air valve.  This preforms the same purpose
as the thermo time switch and extra fule injector because it closes over
time when it's cold, and due to the extra air flowing, it uses more fule.

It may also have an ambient temp sensor that gives the engine a richer
micture, but I'd have to look at the manual I have for Bosch systems.

I've noticed the over-sensitive brake pedal problem in two vehicles;
one was a low-milage Mazda 626 and the other was a U-haul truck.  They both
had power brakes.  I wouldn't call it "super" braking power, it had more to
do with a tiny touch locking the brakes after a cold start.  The brakes would
work just fine after a couple of minutes or so, it was just that you'd need
a reasonable amount of pedal travel to lock them up (IMHO much better).
I'd always thought that it was me getting used to power braking, but now that
someone else has mentioned it, maybe it wasn't just me...

Well, netters, here is my question again.  I've tried it twice, with no
answer.

As many of you know, the Corvette LT1 engine, and now the engine is the
'93 Toyota Corolla, use reverse flow cooling.  That is, the coolant starts
its flow through the engine at the heads, and then goes down past the
cylinder bores before returning to the radiator.  Several advantanges come
from this, including lower head temperatures (thus less pinging) and more
even temperatures for the cylinder, causing less taper when in operation.

With these advantages, why isn't reverse flow cooling used on a wider
scale?  I can hardly believe that it is due to "design inertia" since
the days of the Model T without a water pump.  Anyone???

>Try getting some decent revs outta that old 60's design pushrod engine, 

 I'm curious what you mean by "decent" revs, and why you believe you can't
get them out of a pushrod engine. My own experience tells me that I can
assemble a pushrod engine that is pulling strong at 7000RPM (normally
aspirated '75 odd-fire Buick V-6, 9:1, K-B 1X cam, hi-rev lifters, HD
pushrods and springs, Offy dual-port and 750CFM Holley, stock HEI). This
without the benefit of the larger-valve, larger-passage heads of later
years. This engine lost a little bottom-end torque (might be due to the
carb as much as anything) but goes like a bugger from 3000RPM - up. By
catalog shopping you can make a Chevy V-8 do better, especially if you
use a small-displacement block, like the 283, the 302 Z-28 motor or the
327. As you increase displacement the flow past the valves becomes your
limit, not valvetrain response, and your torque band gets taller and
moves to the left. Big-valve Ford heads will let you spin up nicely,
and unlike this year's "stunning advance" from overseas, you can set
your engine up however you please because there is an aftermarket full
of performance alternatives. Not to mention off-the shelf spare parts.

 You can get a distorted view of things by taking the automotive press
at their word. Ink under the fingernails is a poor substitute for grease.

-> if your tires make a little noise, this is fine -- you get maximum

 Unfortunately, on a conventional cambered road with a conventional
passenger car which isn't balanced for weight distribution, assuming
nothing wrong with brakes, alignment, or tires, most front engine, rear
wheel drive cars will lock the right front tire first during a
maximum-effort stop.  Depending on the proportioning and forward weight
shift, it may sometimes be most efficient to ignore the locked wheel
and let the other three do what they can.

 On most of the cars I've driven, pedal effort had little to do with how
hard the brakes were being applied.  This is particularly true of Ford
and GM power brake systems, which they seem to put on everything whether
it needs power brakes or not.

 We autocrossed a '75 Monza with a 350 V8 for several years.  When you
have a 3400 pound car with over 2000 pounds on the front wheels, you
learn a lot about stuff like that.  We were able to swap '81 brakes on
the back, which were basically the big Impala drums with a four bolt
pattern; that gave us GM wheel cylinder sizes from 5/8 to 1-1/4 to play
with.  Alas, the only possible upgrade to the front of an L-body was to
go to the later model vented rotors.  We'd get about a year of street
and autocross use before the stress cracks in the rotors got so bad we
were leery of running them.  We started changing them religiously after
we had one explode.  Lucky there was nothing hard and stationary around
at the time...

ack.

i saw one of those motors in detroit two years ago; it was an engineering
prototype at the time.  somehow i missed the fact that it had been introduced.

it's a very interesting motor, if it's the one i think it is.
the intake and exhaust cams have unusual profiles; the intent is
that by staggering the valve openings and closings, they can get
the effects of a stratified charge motor without the downsides
that come with such a design.

they also had a prototype 4 valve head for the V-6 on display too;
that one isn't in a production car yet, as far as i know.

 Try pouring 5cc or so of gas down the carb.  Since the formulation
changed back in '86 or so, gas tends to congeal and gunk up the inside
of the carb after an engine sits a year or two.  If the engine won't
start then, try a compression check.
