It COULD be your strut rod bushings. My '92 does a pop now and then usually
brake related. I know my bushings need done, I'm just kinda lazy about
it.... since spending a BUNCH of time under my F-350!!!!

And thanks to Moe for recommending caliper for my Thumping fllorboard...
haven't had a chance to try it yet, but I know the caliper can move a bit.

This could simply be contaminated transmission fluid.
The lock-up torque converters are very sensitive to
this and will shudder as they try to engage if the
fluid isn't CLEAN. (It can feel almost like you're
driving over rumble-strips.)

As a first step, change the fluid (drop the trans.
pan AND drain on the torque converter), add a can of
trans. fluid conditioner (like Sea Foam's Trans Tune) it for a thousand miles and do it again. IF
it's just contaminated fluid, that should do it.

I'm having a problem which I know was addressed before but I don't remember
the solution. Hopefully one of you will and can share it with me. The
plastic bushing which attaches the clutch pedal to the rod in the master
cylinder is worn out. This happened to me once before and I replaced the
bushing which solved the problem for about a year. I seem to remember
someone replacing some other parts of the linkage in addition to the bushing
but I don't remember which parts it was. Which parts probably need to be
replaced, how much should they cost, and how difficult are they to install?

Just signed on to the list...I'm driving an 81 Ford F150 truck that
belonged to my father-in-law. It has 112K miles and has that "bumped and
bruised" look that a truck gets when it's almost 20 years old. The truck
has had all the routine maintenance done, and is in good mechanical shape,
and lately I've been thinking that it's time for a facelift - especially
the interior. I'd be interested in hearing about any replacements/upgrades
that others may have done..especially in the creature comforts.

Yahoo, first day back after taking Thursday and Friday off last week and
time to play ketchup on the emails...
Chuck ask;

He had occasion to call the Petronix folks today and the
engineer guy he talked
to said that they (Petronix) had worked hand in hand with
engineers of
different spark plug companies. What they found was that the
spark plugs
(any kind)would not work very long if anything more that
25000 volts went to them.
What can you add to this Phred?

I am not sure how much output voltage is actually measured from a 6A
ignition but the catalog indicates45 kV with a Blater Coil. But I wonder if
its the voltage that is critical or the actual current times the voltage?

Well, I spent the money for Platinum's awhile back thinking that in
addition to the performance of the MSD ignition I would get added
performance with the Platinum plugs. Initially I could not tell the
difference, but after about 2000 miles (that's about 2 months for us) the
engine developed a serious miss. Figuring that since my plugs were new, I
went about replacing cap, rotor, and wires without any success.
By this time I did the unmanly thing, broke down and asked for advice from
the MSD customer service guys and everyone I spoke with said the same thing,
"stay away from any platinum plug if you're using an MSD!". I don't recall
why this is such, when I am not running around catching up on things, I will

Since, I have used the factory recommended plug but one heat range cooler
(because I use propane 90% of the time) and have run the Motorcraft plugs at
least 20K miles each set. The truck has +174K miles on it today and I
believe I can count on 1.2 hands the times I've changed plugs, so 174
divided by 6 = 34.8,...hmmm - confession time;

Hi my name is Phred and I do not appreciate how the engine
compartement is layed out on the 5.0L, appears the designers purposedly want
to discourage people from working on their own vehicles...Okay, okay, just
venting here...

Can I attribute using the MSD ignition AND propane that keeps the spark
plugs clean and functioning? Most likely in addition to regular maintenance,
oil, and filter(s) changes.

For what its worth, the tech guys recommend the Petronix products on a
regular basis. Apperently its good stuff.

Hey Chuck, what is "FCA # 07175"? Interesting Ham radio operator call sign?
Sorry but I can't seem to get my act together today.

Does anyone have the 6-Off-Road ignition? It says it is
waterproof and shock proof which seems like good options, but it is about
$80 more. It also says that over 3000 rpm's it gives a single spark, rather
than the multiple spark at lower rpm's. What is the difference? More over,
what would be the point of that? I don't fully
understand the benefit of a multiple spark, as apposed to
one long spark. I
checked the website, and it still is not clear to me.

Well Rob, the Off-Road MSD 6 is just a "potted" ignition, in other words
its full of epoxy type material that is super hard. There is nothing really
different except that it has a rev limiter option via a short harness and
plug (trailer type connector). Is it worth the extra $80? If you plan on
doing a lot of mud boggin then most likely "yes", but for rock crawlers like
me that cross an occasional stream, then "nope".
The epoxy is no doubt rock hard, you will break the blade off your Buck
knife before chipping it, and it serves two purposes, one to waterproof the
unit and two to isolate the components from vibration.
At 3000 RPM the 20 degrees duration is not enough time for the ignition's
oscillator circuit to give you more than one spark. So the result is you get
one spark that will last the entrie 20 degree duration.
At lower RPM's the time to complete 20 degrees of crankshaft roation allows
the ignition oscillator circuits to produce more than one spark, so the
lower the RPM's the more sparks.
Autotronic (MSD) could make an ignition that would generate one long spark
that lasted the 20 degrees of rotation at low RPM's, but then the size of
the transformer and capacitors in the ignition would get a little on the
ridiculous side and certainly drive the cost of the unit upwards. This is
just a compromise. I hope this clears up a few questions you posed. Feel
free to contact me directly if you wish.
By the way, if any of you guys ever have any problems with some of the
products this company manufactures, let me know especially if it involves
repair work. I am a firm believer in providing customer service.

Have any of you installed the MSD ignition in a truck with
the 300 I6? Does
it make a noticable difference either in mileage or power?
I've got a 92
F150 with the 300 and Borg/Warner 4 speed. The only
modification is a 3"
Gibson cat back exhaust. I tow about 4,000 pounds with my
truck and would
love to get a little more power out of it.

We have a couple of guys that run the MSD 6 on the same engine and they
have had favorable results with both mileage and power. Noticably one guy
claimed that he can stay in overdrive (his Mazda 5 speed box) going over the
mountain pass here in El Paso whereas before he would be forced to
downshift. Not sure what his mileage figures are, but if you want I will ask
him tomorrow - its getting late here.

Andy asked regarding MSD & Duraspark;

Here are the questions:

1. Is the 6A compatible with the Dura-Spark ignition?
2. Will I notice an improvement over the Dura-Spark?
3. Does MSD sell a kit which will save me from cutting the
stock wires?
4. Will the 6A "box" replace the function of the DuraSpark


1. Yes, if you like, send my a fax number and I will send you a diagram on
two methods to wire in the MSD ignition with a Duraspark box.

2. Most likely you will. The Duraspark box is not "hot" ignition, but it is
very reliable. Sort of like the GM HEI ignition system, sure it stands for
"High Energy Ignition", but compared to what? the previous types of
ignitions that is points? Oh yeah sure then it is a High Energy Ignition.
Sorry to mention GM on a Ford list, but I felt it was necessary to make a
point. Sorry if I offend.

3. Oh oh, ask Don Porto how his ignition is working. His "PN 8778 - Ford
Adjustable Timing Control/Ignition is literally a direct replacement for the
Duraspark Ignition module. It is not a Multiple Spark Discharge but it is an
enhanced little puppy that also allows a range of 15 degrees of adjustment
while he is driving. This is done via a knob pot that can be mounted on your
dash, if you are pulling a load, and come up to a steep grade, just dialing
back the knob retards your timing.

4. Not sure what you mean, but you could do away with the Duraspark box and
run completely off the MSD ignition. Your trigger signal would now trigger
the MSD and not the Duraspark.

And to the OZ-Man himself, considering that Ford has the GFI system on
their OEM environmental fuel vehicles, I would rather wear pink. The system
is not reliable, I am dissappointed that Ford would even consider such a
system, but it happened. Ask about their sales of such vehicles, I bet its
not much at all. However Ford does plan on giving the Bi-Phase system a try
in Mexico this year or next (not sure exactly when). That will be the system
to have.

The place is closing down for now, must go.

Just got the newly rebuilt carb back on that 4.6L. Started up right away
but seemed
to be starving for gas. Was gonna investigate til I remembered that the
Black Silicone
valve cover gasket material had to sit for 24 hrs so had to shut it
off. Oh...while the carb
was off I did pull the valve cover 'cuz it was ugly and needed paint and
new gasket stuff.
