Subject: Apologies for any misinformation
It's been a busy 24 hours...
Have decided Laurinburg's suppposed A/C guru isn't so wise after all.
Took much of what he said as Gospel. Now will not repeat ANYTHING he
says. Yes, he's been messing with A/C longer than any of us, but
really don't think he's got the full grasp:
Asked following questions at lunch:
Why is DeLo accumulator on low side where nothing is being metered?
If high pressure occurs after liquification, why is DeLo high pressure
port BEFORE condensor?
He honestly couldn't answer, and proclaimed DeLorean a hopeless anomaly
So...
Stopped by GMC truck owner's house after work to really examine its
system. IS 100% IDENTICAL! (high side gauge port further down line).
Uses orifice tube metering device. Accumulator located AFTER
evaporator (that one still has me befuddled) with a low pressure
switch. Etc. If you can work on GM A/C, you can work on DeLorean.
Systems are totally the same.
Also examined my pressure switches at lunch. Low pressure switch
indeed two conductor -- just has extra line taking off elsewhere from
one terminal. High pressure switch is odd -- CLOSES at normal
pressure, but OPENS when there's a fault. Totally backwards of what
you'd expect. Fired up A/C and water poured off my accumulator -- no
doubt is on low side.
Also popped hood of one of the Lincolns and guess what I found on
compressor -- a pop off valve! Never noticed before. Looks just like
DeLo valve. Guess that's where Ford decided to put high pressure
protection. Rest of system of course totally DIFFERENT from DeLorean...
Background info: back in my R12 days took a new-to-me Lincoln to 3
different shops to make A/C work. No one could do it. That's how I was
introduced to Guru. If anyone could do it, he could. Well, he replaced
every single component (am sure that's why Two Tone Lincoln's A/C now
outperforms all the others) and still couldn't make cold air come out.
Car was proclaimed hopeless. I sat down with factory literature to
study the situation, and that's when it hit me: CAR HAD NO LOW SIDE
PORT. What everyone had been using as a low side port was really just
a guage attachment to diagnose throttle suctioning valve. In
subsequent trips to junkyards popped hoods of every '79 Ford -- not a
single low side port on any! Ford did not use low side ports in 1979.
Unfortunately my factory literature is 1978, so I have no idea how
they suggested anyone charge the system. Transplanted a low side hose
from a '72 LTD (so much for theory that hoses themselves become
pourous and leak). Also converted to R134 because that's all I could
buy (tools and freon). Imagine thrill when ICE cold air hit me in face
(from my "hopeless" car). Sealed the fate -- subsequent cars or failed
systems have all been converted to R134. Now have only one vehicle
still burning R12: an old blue AMC that will soon be given to my
little brother...
Again, apologies if any misinformation was repeated. Physics of freon
remain unchanged (evaporates even colder than freezing point of water,
condenses back to a liquid under pressure, etc), but some of the finer
points were definitely off. A clogged system will NOT return to static
pressure. High pressure is high pressure whether freon is liquid or gas.
And I just had a thought: does location of GM/DeLorean accumulators
have anything to do with cycling compressor? While the thing is
sucking obviously no freon is going to accumulate. But if it cycles
off, does accumulator give evaporating gas a place to expand until
compressor comes back on? Kind of like fuel accumulator? Would allow
system to continue cooling. Don't know, but it's in that particular
location for SOME reason.

Subject: Re: Air intake performance
I hear this a lot, regarding the mixture valve. I haven't driven my D
yet enough to know either way, but I have an idea about another
complaint that I've heard a lot of...
Most people I talk to say the PRV runs hot. Most say they'd like them
to run cooler or have better airflow in the engine compartment.
Isn't there a way to turn at least that passenger side breather gill
for the hot/cold air mixture valve into some kind of vent that washes
air over the engine? Perhaps some kind of duct, or maybe even a small
electric fan with a diverter?
I realize the engine doesn't see much air movement being mounted in
the rear, but at least the cover is well ventilated, and it has a lot
of room around it (relatively speaking). I'm suprised to hear folks
say it runs so hot.
Also, for those who are interested, I've finally got all my
transmission brackets, clutch lines and pieces all hooked up. I can
finally get back to the engine/head work (and work standing up, thank
God) I hope to crank it over during the first week of July.
Ever work on a car so hard, when you're done you're afraid to start
it up?

If what Andrew says is corect, I would say this is a bit of an oversight
- the fans are just as likely to have their wires pulled out than of
getting jammed and drawing too much current. Surely the fan-fail light
should tell you if one or both fans have gone either short or open
circuit? - I know the original device didn't, however it was something I
designed in to my Fan controller module. Can you confirm, Bob?

For as long as I've owned my DeLorean, I've never seen the car run
hot, unless I've had a radiator fan go out. And then I can tell,
because the needle passes the 220 mark. Otherwise, the temp always
stays low. Depending upon ambient temperature outside, the needle for
the coolant temp may not fall quickly like it does in the winter, but
the motor does stay cool. Then again, when I first got my car, I had
the all metal, 3-row radiator installed, and most importantly, the
cooling system is totally bled in my car.
It doesn't matter wheather or not you use the automatic bleeder kit,
or you bleed the system manually. You just need to bleed it. That I
would consider to be far more important than air flow across the
engine. Although, I don't even really know how much airflow over a
motor really helps at all. Lifting the hood on a conventional car,
and the engine cover on a DeLorean, both engine compartments have
always felt just as warm to me.

Moderator's note: some of the computer tech stuff is drifting away from the subject line of the mailing list. If I can't find a DeLorean connection it may not get posted.
Hi,
I'm a long time lurker, but this one thread has caused me to come out of the
cave. I've been working in the .com industry (for better and worse) for
eight years, since browser versions 3.x and such. Where I work we have 98%
user IE5 and 6 usage, 1.9% Netscape of various flavours. I say use all the
_javascript_ you want, as long as it's done well. There's no reason at all to
suppose that properly written and tested JS will bork browsers. We run a
sophisticated web based tool set and it has been tested on pretty much every
graphical based browser out there, even AOL 6.0 using a dialup connection on
a Mac (the acid test).
The moral of the story is, as with anything... if you're going to do
something, do it really well. Sort of the attitude that most everyone takes
when dealing with their DMC.
While I'm here I'll also say to the person that mentioned about two weeks
ago that they can't stand Montreal: I've been living in Montreal since March
of 2002 and can attest to the fact that it is an incredible city!
Incidentally are there any DMC owners in Montreal?
Cheers,
Chris

Subject: Venting outside air over engine
Would love to route some air over my engine too, but don't think
passenger side grill is the location. Engine intake really has to be
connected to outside world. At 95 degrees, on a treeless highway, with
hot freon in the condensor, and coolant above 220, my fuel mixture
will predetonate (full throttle) if it's breathing under the hood.
Guess hot air is last straw. Did clear up at higher octane (suggestion
for summer driving).
Even though our engine compartments are brutal, are plenty of DeLo's
that have been driven 100,000 miles that way. Probably pushed the
limits of heat endurance, but they made it. Given lack of options
(other than Q panel vents, where would re-routed air come from?), best
option may be to keep cooling system at peak maintenance and lubricate
with heaviest possible oil. Driving on the edge.
BTW: actual condition after purchase of cooling system in my
advertised "maintained" car makes me wonder if a future rash of heat
related failures, akin to recent TAB problems, is waiting.

He'll correct me if I'm wrong I'm sure...;)
I've only heard about this "other" radiator in passing. What's it
made out of? Who sells it and what does it cost? I have been educated
with regards to the importance of bleeding the cooling system, and I
plan on buying a constant bleed kit from a vendor. I don't understand
your reference to bleeding the system from inside the car however, or
do you just mean to say that your system is always bled?

Subject: Re: Venting outside air over engine
Intake air and coolant are the important items in maintaining proper engine
temps. The air flowing over the exterior of the engine pays a pretty
insignificant role. The main thing is allowing the heat to dissipate away
from the engine compartment and the Delorean seems able to handle that
pretty well. Coolant temps of 220 degrees are a bit high but aren't that
extreme and I've yet to see a properly tuned DeLorean without a turbocharger
that will pre-detonate at 13 degrees BTC ignition timing. One thing to
remember about the DeLorean is that the fuel tank is directly down wind of
the radiator. Also, the fuel that isn't used recirculates back to the tank
from the engine picking up heat on each go around. Deflecting the radiator
air flow away from the fuel tank would, IMHO, be benificial. Any air routing
in the engine compartment area would be best directed at the intake system
and not simply blowing cool air over the top of the engine. One thing I
found on my car, after several years of road trips, was that the radiator
fins started filling up with dirt and bugs. The AC condeser fins are
spaced wider than the raditor's and the dirt passes through the condeser
but hangs up in the radiator fins. You can't see the front side of the
radiator fins without removing the radiator from the car. Because of it's
location, it's very difficult, if not impossible, to blow out the entire
finned area while it's in the car. When I removed my radiator it was about
30% blocked. I installed a triple core metal tank radiator and have
experianced no heat problems since.

Subject: RE: Venting outside air over engine
An interesting phenomenon I encountered when I put the BTTF build on the
back of my car is how much cooler the engine ran while I was driving. When I
built it I left the exhaust vents open to the engine cover vents. While in
motion, I get a Bernoulli Effect across the top of the vents creating a
vacuum at the back, thus sucking the hot air out of the engine compartment.

Actually, that isn't quite true. Almost every article
I've read and dyno charts I have seen show that total
removal of the intake assembly does NOT produce the
best performance gains.
Because I travel over a gravel road almost daily
during the summer, I was getting dust on the throttle
plate and the air filter was "clogging" much more
frequently than desired. I was also pulling in hot
air off the engine since the twin turbos require the
moving of the alternator and this, in turn, requires
the removal of the stock "intake tube".
I now have the same air intake that Ron Wester has on
his "Screaming Yellow Zonker" DeLorean.
PURISTS READ NO FURTHER!!!!
Essentially, we cut an opening into the passenger side
rear pontoon and placed a very large K&N filter in the
pontoon. Then we ran a 3" I.D. tube to a throttle
body cover from a Vortec engine.
Several things were accomplished by this. First, I am
now receiving "cold air" very efficiently. The enigne
breathes very nicely with noticeable gains in
performance and mileage. Second, the throttle body
plate stays immaculately clean. Picking up the air
where I now do eliminates the dust sucked up into the
engine compartment. Also, the new "hat" is held on by
a hose and clamps. This eliminates the dust seepage
around the o-ring at the throttle body.
IMHO an air flow over the engine will not do much for
cooling the engine. It would, however, be nice for an
intercooler for those of us with turbos.
A final thought on "hot engines": Early in my
DeLorean ownership I experienced overheating on a
somewhat regular basis. Since switching years ago to
the all metal, triple core radiator and adding the
self bleeder, I have had zero cases of overheating and
that includes being stuck in stop and go traffic in
100º+ heat for nearly an hour.
Just my personal experience.

Need a favor.
Can someone measure the voltage at coil position #15 with key on/run

Need to verify that mine is not right.

I have just done this job and heres a tip...well it worked very well for
me...
Using a decent 11mm 6 point socket apply reasonable torque to the nut then
keep hitting the socket with a hammer and it will give way just a little as
first and just keep tapping away until the nut moves freely. If the nut is
badly corroded to the stud then the stud hopfully will come out complete. If
you do snap any studs they normaly snap at the manifold. When you are left
with studs I strongly recomend getting a decent roller-type stud extractor
like the Facom 287B.7 ( someone on the list said you can get them at Sears
in the US? ) then again apply reasonable torque on the stud and just keep
tapping with the hammer until it comes free.
I also strongly recomend NOT using any heat unless you really know what you
are doing. I tried heat and it caused me problems with 2 studs, the other
10 I used this method and it worked perfectly
> What are the torque settings for the exhaust manifold?
Rob Grady told me the manual says 16lb but you can go to 18 tops..he also
said something about not using anti seze on the studs
Id be intrested to know how you get on

Has anyone run across either a universal dead pedal or one made specifically for the Delorean? Has anyone found one that is close enough to be easily modified to fit?

Subject: Steering rack stiction
My steering rack is sticking now that it's hot and I'm doing all of my driving with the air on. It seems when the car is cool, the steering performs flawlessly, but as it reaches operating temp on 80 degree days, the steering rack seems to heat up from the radiator and begins to exhibit stiction. The wheel sticks where ever you tend to put. I've pulled the pinion cap and loosened the spring tension on the nylon slider by adding 2 custom paper gaskets to raise the pinion cover, but it only delays the effect and makes the steering a little looser when cold. It's been topped off with 90wt gear oil. Any one else experience this feature? Any suggestions.
Thanks,
Jim 6147

Subject: Re: Torque question
I don't believe it is specifically listed in the manual. However, I
used the M10 bolt spec of 11 lb/ft or 15 Nm. I also put the torque
to the nuts again about 15 min later because it looked to me like
the gasket would compress some. I got a bit more movement to the
torque wrench click. So far so good at about 8,000 miles on the job.
