Phil,

You are making me nervous! I don't think I mentioned anything about
an SRI(?). I was talking about the STI (Self-Test Input). I think John
Strauss' advice is probably the way you should go...get a good manual.

On my 3.0l Topaz, the STI is the single wire clipped to the EEC-IV
connector. The SRP (Signal Return Pin) it the is the upper right pin
when looking at the business end of the EEC-IV connector when the four
pins are considered the 'bottom' of the connector. Now your vehicle
may be different (can't remember what you drive...'94 F-150 - I6?)

(Ya know, when you start to get up in age, the second thing to go is
the eye sight.....can't remember what the first thing to go is )

Any ways, I just made a little wire up with male spade ends that would
fit the EEC-IV connector. With the SRP (Signal Return Pin) connected to
the STI (Self-Test Input), when you turn the key _on_ (not to start),
the EEC-IV will start its diagnostics. This is know as the KOEO (Key On,
Engine Off) test.

KOEO first initiates a self test of the processor, verifying control
module memory integrity and processing capability (much like when you
boot up your PC). Then it verifies that sensors and actuators are
operating properly. The system will then send codes for any failure(s).

Next it send a Seperator code 100 (but since the MIL doesn't show
zeros, it will appear as a code 1 with a loooong pause. Then the system
checks the KAM (Keep Alive Memory) for any stored codes. These codes
can indicate chronic amd intermittent problems that happened in the
past but are not now present. These are also know as "Continuous
Memory codes).

Note that in 1993 a lot of the terminology for the EEC-IV systems was
changed in an attempt to standardize the terms from one model to the next.
As John said, it would be a worth while investment to pick up a good
manual that is compatible with the version of EEC-IV that you have in
your vehicle. Heck, you may even have the EEC-V model if your vehicle
is new enough!

Could anyone in Fordland tell me the correct engine color for a rouge 337
engine? The engines were used in the 48 thru 52 F7 and F8 trucks, also in
Lincolns of that era. I need the color for the truck, not the car. They
are typically different. Thanks, Lee

Kevin,
The "WDM-BR" is the axle model number. (I think it indicates the size
of the pinion bearing, number of splines, and the
number of differential pinion gears (2 or 4).

The "86B" is the manufacture date (Year, Month, Week)

The 2.75 is the gear ratio for a conventional diff. (If
it was a traction-lok it would be 2L75)

The "9" is the ring gear size in inches (as someone
previously posted.)

The "385B" is coding used by the specific plant that
produced the axle.

Hope that is of some help.

Message-Id:
Content-Type: text/plain

I understand very well what a PCV valve does and how it does it. I also know
that the PCV valve dumps these gases into the carb. I thought to myself "this
must lower power". I also thought that removing the PCV valve would not hurt the
ventalation since the vacuum does VERY little anyway. I would just leave the
vents open and give it a try. My engine in not worn out (1200mi when I did it)
and it has not caused any oil leaks (80,000mi now).

I fully understand everyones pionts, but one thing I do not understand. How can
someone sit there and say "That just will not work. I have never done it, or
seen it done, but it will not work."

I have done it and it works. Yes the EPA my track me down, but THAT WAS NOT THE
POINT. The point was that one could disconnect the PCV valve (WITH HARM) and
gain power and mileage (say, in a 'off-road-only' application)!!!!

I change my oil evry 4000mi and my truck still smokes Z-28's (even after
80,000mi). (ie., no acid build up.)

One last point: Many older cars did not use a PCV valve and did not suffer from
any of the problems anyone has mentioned. (Sure, a few were more prone to oil
leaks, but that was due to the old gaskets. New gasket material is much better
than the past). ALSO, many new cars do not use PCV valves. If the PCV valve is
the holy savior of the internal combustion engine then why would some new cars
not have them?

I would have loved to hear what you guys would have said to Henry Ford about his
"Horseless Carriage"!!!!

I have a 1955 F-500. The grill looks like a 53.

Does anyone know anything about these?

Is the cab the same?

It's got a flathead in it. Can these be built to be reliable for say =
50,000 miles or so.=20

Everything I've seen is about F-100's.

If I ever get around to it, this will be turned into a daily driver =
parts truck. It has a dump so maybe I'll make a roll off bed for =
transporting cars or something.

Any info will be appreciated.

Thanks in advance

Ok Tony try a few of these....

1). Check belt tension as mentioned before Possible but unlikely
2). At night ( obviously the best time to see the bulb ) Start with no
accessory load just the motor running do you see the light yes or no,
Next start loading the system with accessorys one at a time A/C blower
on low step to speed and so on to high, then headlights ect.. while
doing this observe the light dose it increase in illumination with each
step ? If it dose your fighting an alt or voltage reg problem. More than
likley a diode in the alt. is decaying under load this should be tested
by your dealership since you still have a warrenty.

Okay, I have a simular problem, My amp gauge at times will go all the way up
the red on the 18 side. To make it go back down, I have to turn on the
headlights, and the vent full blast in order to get the amp gauge back to safe
position. Now does anyone have any ideas? The alternator is brand new.

That surely must be a symptom that the carb was already much too lean at the
mid/low end, and/or You have a vacuum leak. Or the wrong PCV valve...(or bad)
The PCV is simply a calibrated air leak into the manifold that the carb must
be jetted correctly to compensate for. It also has a spring loaded plunger
that "closes" the valve(mostly) under high vacuum so that excess crankcase
air doesn't swamp the carb mix at idle and light throttle. At anything past
low mid throttle openings, the amount of air admitted by a working PCV is
insignificant compared to the amount of air entering the manifold via the carb.
Stock carbs should be fine with the stock PCV valve. Different carbs may
need some minor jetting to put things just right.
Also "wild" cams can screw with PCV by not pulling enough vacuum to close
the valve at idle.
I still maintain that if removing the PCV helped mileage or power then You
have simply masked another problem.

I have no oil leaks (even after 80,000 mi). If my engine is worn out then I
>will take my worn out mileage (average 17/highway 21) over a *good* engine any

But if the PCV and *everything* else was working correctly, You would still
have *all* that, plus spew less pollutants into the air...

Don't be lazy, fix the real problem, hook up the PCV and we can all breathe
better.


>Just to let you guys know, not all cars used a PCV valve.

Well, no, not before about the mid sixties...
Not everyone had it figured out yet.


>As a matter of fact,
>some NEW cars do not have them!

I haven't yet seen a new car that didn't use PCV in one form or another.
Sometimes the goods are in hard to reach, impossible to see locations, but
it's there.

I'm game though... Name 2 new cars that don't use any kind of PCV.
Maybe I'll learn something interesting out of all this yet.

Happy motoring,

Un-calibrated voltmeter. To check, with the engine running, measure the
voltage accross your battery. If it's between 13.8 and 15 volts or so, the
problem is your meter, not your regulator. Otherwise, your regulator is toast.

Incedentally, you have a voltmeter (the gague that goes from 8 to 18 if my
memory serves me correctly) and a charge light. The charge light lights up
when the battery is discharging (a negative ammeter) and the voltmeter shows
you the voltage of the system. The voltmeters are hardly precision
instruments, so if you suspect a problem, check it out with a hand-held meter.

Thanks, good discussion. Here's something I've been wondering about. My 51
F1 flathead V8, as you'd imagine, has no PCV system. It has a 'road draft'
tube running from the top of the block, curving down the front of the engine,
through a belly pan, where it ends in the airflow under the truck, cut off in
a bologna slice. I assume this is supposed to create some slight vacuum, or
crankcase ventilation, when the truck is moving. There's also a vent tube
(doubles as oil filler) with a filtered cap. At rest after the engine is
shut off, this no longer functions as an intake, but wafts a little of that
noxious vapor you describled. If a person wanted to install a PCV system, by
putting a PCV valve where the road draft tube is, and connecting it to the
manifold/carburetor adaptor block, how would one:
Determine what PCV valve to use?
Figure if the vent to the intake needs to be metered (certain size hole)?

Any thoughts off the top of anyone's head would be welcome.

Wow, you have one of those? I've never seen one. Can you get parts for
them? Hot Rod parts, for instance? The hot trick used to be putting the big
Lincoln flathead in whatever little light vehicle was handy. I have the Merc
(255ci) in place of the original Ford (239ci) in my 51 F1. How much more do
the 337s weigh? How much bigger are they? Etc, etc? FYI, my flathead info
(from a website, http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.agt.net/public/bboogaar/flathead.htm or
http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.fullnet.net/user/mulligan/, not sure which) says they were also
available in '53 in the trucks.

Subject: 67 F100 questions
Message-ID:

I sent off for and received the build sheet for my 1967 F-100. I have some
questions about it for some of you old truck geniuses:

1. Mine has the stock ammeter and oil pressure gauge specified on the sheet.
It's still there. Does this necessarily make it the "Custom Cab" model? It does
not specify this on the sheet but I always thought that dummy gauges instead of
dummy lights were a custom cab feature.

2. The sheet states that it came with front and rear shocks. What, is this
special or something????

3. Dana 3.54:1 Limited slip differential is stated. I have been under the truck
and it's still there. Is this a good reliable/trouble free rear end? I guess
since it is limited slip that it has a clutch assembly in it. Do they wear out
more often than slip-all-over diff's? Also, what Dana/Spicer model is this? 44?

4. 352 2V low-compression engine is stated. It's still there (some may remember
my questions a month ago). *Woof* *Woof*! It's a dog!! Exactly how sad should I
be about this? Last time I drove it, it seemed pretty damned torquey, but that's
judging by today's rice-grinder standards. Would anybody know the possible stock
compression ratio? I'm thinking 8.5:1 or so. Also, are the heads supplied with
2bbl motors different from those supplied with 4bbl motors?

5. Has anyone emailed Ford for further info after having gotten a build sheet?
Do they do this?

This truck was built 32 days before I was born, so it's like destiny. I've bled
on it and I love it. I want to keep it forever. Any and all help would be
appreciated.

Again NO other problem. Everything woorked fine before, just better now! No a
PCV valve is not just a controlled air leak, it is "junk" air. It would be kind
of like hooking the carb up to the tail pipe.

THen why is everyone else only getting 8MPG?

Since I am getting around 10 (or more) MPG better than most everyone else I am
putting LESS pollution into the air even without the PCV valve dumping into the
carb.
BTW, I wonder how many people have the charcoal canister hooked up on their
Fords. The lines rotted away pretty fast. I have only seen one that works, and
it is one my truck!

My Chilton Truck and Van Repair Manual 1971-1978 agrees with you on the dates,
but Chevy doesn't list any PCV system in my manual!

OK all new cars DO vent the crankcase, But not all new cars vent it into the
intake!
The list is long. Go to a dealer and look.
The Viper & LS-1 do not vent the fumes into the intake.....
