I know you probably didn't miss me but I just got back from a business trip.
My company sent me and my wife to a business meeting/Christmas party for a
job well done last year.  When the plane landed they drove up to the 757 in
a white 79 Ford pickup with a aircraft stair body on the bed so I could
disembark from the plane in BERMUDA!!!  Sometimes I really like working for
this company.  I was there for 3 days and Carol and I had a good time.

The driver for the transport service I hired to take us to boston told me
they have all Ford equipment.  1 Lincoln, 1 Mercury, and 2 full size vans.
She said the 2 vans both had over 400,000 miles each on them and both had
the original untouched motors in them.  1 had a new transmission and 1 got a
new rear end.  She said this was the one they use to pull a trailer with.
Not bad though for 800,000 combined miles.


Sorry if I'm rambling but I'm a little punchy right now.

Steve that's a nice stable of Ford horsepower you have listed there.
Congrats on the new purchase.
Simplest question first, When you check the fluid was the tranny warm,
engine idling, trans in park or neutral?  If these conditions are not met
then the fluid will read high on the stick.  Then when filling the trans
since you get a high false reading you don't put enough in.  The symptoms
you list sounds like what I experience when my fluid is low.

If it goes into all but high gear I suspect the fluid level is now too low or the modulator is bad or the air line is off the modulator.....If it only does this after warming up but works normally when cold then it may be more serious.  You may have some valves hanging or the clutch pack itself may be hanging when warm.  Normally low levels will affect the 2-3 upshft at all temps.
 Any ways, after filling with the correct amount fluid, the tranny
 shifted fine agian in the foward gears, but agian once the tranny warmed
 up, it would not shift back into drive.

You guys must be getting tired of hearing about all my failures the last two weeks but here I am again with a different computer case but the system now seems to be working as I hoped and I can actually access the modem and receive and send mail now.....WHEEW!  what a fiasco!

Anyhow, it looks like we might be getting some snow again so I'm going to go out and work on my plow some more.  This Meyer plow is in pretty good shape but had to replace a hose and fitting and drain the oil and refill it.  (I'm an expert on filling them now, only 4 plugs and 4 hose connections to dink with :-)) BUT......I have a question.....my side to side thingy doesn't seem to work properly, it moves ok but you can push it back and forth by hand.  I suspect there is a valve that must be leaking to allow this??

Well, I am probably not a GURU but I do know that reverse is usually the
last thing to go on a C6.  It sounds like you have a worn pump or some
other hard part that is causing a low pressure condition.

True, 75-79 Dodge wheels won't fit.  You want to avoid full-time 4wd Dodges
of this vintage for just about anything, except looking for a Big Block 4wd
tranny (they only came in these year trucks behind 440's.)  In 80 Dodge
came back to their senses and put the 5x5.5 lug pattern wheels back on
their trucks, along with bigger bearings for the wheels.  I have a set of
83 aluminum Dodge wheels on my 78 right now as snow tires (15x7 rims with
32x10.5 Swampers, I normally run 15x10 wheels with 35x12.5's.)

Ok, this is sort of a test.  I'm trying a sig file instead of building it in
outlook....BTW, I now have outlook back on line and am on my computer again.
I downloaded a new copy of Internet explorer and it fixed all the problems I
was having so I can use the full outlook package again (whoopee!).

Just a note about my last two weeks....first I decided to
upgrade.....upgrade didn't play after plugging.....modem died, then power
supply just when I got it all working again so I'm going after a 300 w power
supply to get my tower back on line (I hate desk tops).

I ran down to the Auto parts store and picked up a new swivel connector for
my Meyer plow and am on my way out to see if I can get it all working before
we get covered up.  It's 30 degrees, greasy but not really snowing much
right now, maybe it's just a hoax :-)

Well, I see my formatting didn't come through, back to the drawing board :-)
Oh, there it is :-)  I'm composing this in RTF, hope it works :-)

Lucky you, my computer's tellin me its 2° looks like its still snowing pretty
good (since about 10:00 last night) and the wind is whipping it up into some
nice drifts ...

AND the 1 U-joint I didn't replace when I had the front end replaced is apparently
bad as there's an odd pop every so often from the driveline in 4wd, so I'll
probably take the afternoon off (its finals week so its pretty slow) and see
if I can replace that joint.

Just lettin you know it wasn't a hoax for us.

Subject: Limited Slip Dana 60 Rear?


Hey guys,

Just a quick question regarding my D60 rear.  In the process of doing my
brake/bearings/etc. this weekend I tested it to see if its a limited slip.
I jacked up both wheels and put the axle on stands then rotated one wheel
forward.  The opposite wheel when in the reverse direction.  Usually this
indicates an open diff correct?  Or is it possible my LS is shot?

Its currently low on fluid.  I pulled the plug and could only barely feel
fluid with mu pinky fully in the hole.  How else can I tell if its a LS
rear without pulling the pumpkin cover?  BTW I looked for a tag on the
pumpkin but no dice.  Or would you suggest I do that now anyway since it
doesn't seem to be working correctly?

One more datapoint.  A week or so ago I had one wheel jacked up and I
could spin it with the other wheel still on the ground and not moving.
Wouldn't this indicate some sort of clutch system or am I all wet again?
It felt like something was giving some resistance but just not much.

TIA.

Sounds like an open diff to me.  Even if there was a limited slip in
there you should have at least a little resistance.

If you plan to drive it at all please fill the diff fluid to the
bottom of the fill plug.  All in all it sounds like you have a
regular open diff.  It can't hurt to take the cover off and take a
look, give it a good cleaning and fresh fluid.

I would say the truck was in neutral allowing the drive shaft to turn.

Subject: choke
Date: Mon, 11 Dec 2000 14:39:27 -0700

List:

Can someone clue me in on correct automatic choke operation?  I suspected
that mine was not closing for cold weather starts, since the engine starts
and runs rough, until it warms up.

Upon inspection- sure enough, the choke was nearly completely open during
cold-starting.  Additionally, it did not fully open after warming up.

I discovered the choke valve to be stuck in its 'nearly' open position.  The
binding point seemed to be inside the little vacuum plunger inside the choke
mechanism.  (Does this make any sense?).

Well, I got the mechanism freed up, so now the choke valve opens and closes
freely (by hand), and opens fully when the engine is running warm.  However,
it still does not close when starting cold, and to be honest, I don't
understand what is supposed to happen to get it closed (automatically).

I think I understand how it's supposed to open (rolled coil of metal warms,
expands, thus pushing the choke valve open), but what triggers the choke
valve to close when it's cold?  Is that little vacuum plunger supposed to
push it closed?  (I'm not even sure if it's actually a vacuum plunger).

Sorry for the tedious questions, but TIA for your input.  (you all are a
great resource!)

P.S.- thanks for your help with my power steering leak.  A new o-ring behind
the large threaded fitting did the trick- no teflon tape necessary.  Also, I
finally got my emissions stuff on (sort of) and passed the inspection, but
I'll leave the details for another time.

Hey Guys,

I got the power steering setup on my 67 F-100 yesterday.  Works very well,
not quite as good as I thought but I can park the thing and turn it with one
hand.

This is what I used.

FoMoCo Steering gear from a 72 F-250(same gear though 79)
Pulleys and pump from a 74 F-250 with a 390FE
Driver's side engine mount from a 72 F-250
Power steering shaft from a 68 with a FoMoCo box
new hoses and belts (74 F-250 w/ 390 V-8)

Total cost was about 200 bucks not including fluid and little stuff like
hose clamps.

The steering wheel is still out a bit, i.e. the shaft is too long. I
measured it all and compared and it should have fit like a glove, but, alas,
it didn't.  Looking to take it out again and have it cut and re-welded so my
damn turn signal will turn off.

Overall it was a success!  Power brakes next...any input?

Thanks for listening,

Other than taking off the cover spinning the wheel is the only way I know of.
If you suspect you might have a limited sliptry filling the oil up.   With
no oil the clutches tend to start drying out and no longer grip each other.
Just my opinion.

I myself prefer the manual cable choke myself but my understanding of the
automatic choke is that the rolled steel is spring steel and thats what
closes the choke when you first step on the gas before you start the truck.
As it warms up the spring steel relaxes and allows the choke to open. I think
thats how it works.

before you start the truck you need to press the gas pedal all the way to
the floor & then release it.this will  put the choke in the closed position.
as the engine warms up it will open the choke automatically.if you don't
have enough choke,you need to loosen the 3 screws on the round clamp that
holds plastic choke housing in place &  rotate it counter- clockwise(just
loosen them enough to rotate the plastic  housing) it usually doesn't take
very much  movement in order to give you more choke.

Everything in the linkages on the choke side of the carb has to move
perfectly free- the tension of the coiled spring pulls the choke/fast idle
mechanism closed, and slowly lets it off as the engine warms, but the spring
forces are fairly light.  If any crud buildup, dirt, rust, bent parts, etc.
restrict the free movement of parts, it will never work right.

If it's only a  dirt buildup jamming you, it can be very effective to get
the engine hot, and then spray it all down (outer linkages and choke shaft)
real good with carb/choke cleaner spray, with the "straw" attached for extra
force.  Use a good 1/2 can on the thing, until it's shiny and clean.  Soak
up all the extra juice- it's flammable.

The plunger you mention is the vacuum pulloff- it pulls the choke plate open
a bit after startup (against the spring), to give it enough air to keep it
running when real cold.

Dear List,

This is my latest status report on troubleshooting the miss in
my 1978 F150-400.

Many, many thanks to those of you who have provided suggestions.

I took the truck back to the shop this afternoon and left it expecting
it to get a valve job.

I had combined all of the suggestions into a report which I printed off
for the mechanic and I believe he has done most/all of the suggested tests.
One test which was suggested by several was the leak down test.  He had
planned to run this test when he had it before but I couldn't leave the
truck long enough for him to do it that day so it was the
first test that he did today.

This evening the mechanic called me with the latest puzzle.  The leak down
test
does not show leaking through the exhaust valves as expected but
is leaking back into the valve cover area.  He says that this indicates
that it is leaking by the valve guides (Rodney mentioned that he had had
this problem.) BUT the mechanic says that when this happens then the engine
should be smoking and it does not.

Another unexplained change.  The vacuum gauge was reading about 17" at idle
when I wrote the other day but was reading only about 12" today.
Tests for vacuum leaks, leaking hoses, etc. turned up nothing.

It now has new plugs, plug wires, rotor, distributor cap, intake manifold
and
carburetor.  The new plugs are evenly colored.

Compression test is good and values are pretty close.

He is taking it for an electronic analyzer check up tomorrow.

I appreciate everyones input and will be sure to let you know the outcome
when this thing is resolved.

Sincerely,

Dennis Smith

Is its still possible its a LS and just not working properly?

Don't worry I can't drive it yet since its not inspected.  Its only been
driven around the block once and into and out of my driveway.  Not far
enough for real problems.  Now my question.  If its NOT LS will it do any
harm to put in the diff fluid for a LS?  My thought is that its a
malfunctioning LS so I don't want to fill it with regular diff fluid.  Or
am I putting too much thought into this?  :-)

Actually its an automatic and the truck was in Park.  How does that affect
the outcome?

Unfortunately I don't have time to tear this truck apart right now.   I
need something to drive when the snow/ice hits and my '95 Mustang aint
gonna cut it.  I'm getting the windshield replaced tomorrow and after that
I only need to fix the exhaust leak and I should be able to get it ....
