If the thermistor comes unplugged, the engine thinks it is constantly cold and defaults to ~2200RPM. Verify the connection on the thermistor, May be able to reach around from behind the engine to plug it in without having to take everything off.

Subject: AW: front brake caliper/rotor from another car?

Ford Granada, Capri, Escort and some other Ford of the 70s and early 80s
use our calipers. Or let's better say we use their front calipers.

There are also single pistons and gasket kits available. So there's no
need to use parts that don't belong there.

Elvis



Are there any more typical cars that use our same front calipers and or
rotors? I know that master cylinder is the same as a Saab 900 but what of
the calipers? I know that brake pads from a 78 toyota pickup work, does its
calipers work too?

NO ! If the turn lights would make such a power loss ath the alternator,
what do you think would happen when the headlights or A/C is on ? They need
at least 10 times more power !

You may have a bad connection at the binacle or near by.

Elvis




My car has had minor power fluctuations ever since I got it. For
example, the dash lights dim when the turn signal light is on.
Is this an old problem due to the stock alternators/voltage
regulators?

I have talked to many tire experts and they all told me on my 91 motorhome,
81 DeLorean and 65 Corvair, that ANY tires over 7 years of age should be
replaced.   I let the motorhome tires go to 7 years and on inspection they
looked good with no cracks in sidewalls or separation between tread......at
8 years the side wall layers were pealing although the tread looked and
measured almost new.....it has 12K miles on them.  I replaced them.   My
DeLorean has 8k miles on it and as it is over 20 years old, they will be
replaced soon.   They still look and measure like new, but they are hard and
brittle!  It is my second or third car and does not get much use and I
rarely go out on the highway at any speed with it so have been lucky so far.

Subject: Re: idea for the group

There are a lot of posts on no start, hard start, rough idle, high
idle, hot start, dying after running, etc. It is all over the place
and not logically laid out like a flow chart except for the flow chart
on the ignition system. It WOULD be nice to have a fault tree created
especially for the new owner who wants to get his car running right.
Unfortunatly it is a BIG job. Much of this was learned from painful
experience or the experience of others. In many cases it is just a
matter of going over the work of previous mechanics and doing it
"right". Vacuum leaks top the list. They are the cause of many of the
symptoms that lead to getting the car "fixed". Another issue is that
most cars have multiple problems. When you fix the "big" one you
uncover many smaller ones. For example a car won't start. You finally
get it running but it won't idle right. Well you didn't know the idle
was a problem because it wasn't running! Now you have to dive into the
systems that control the idle. Now it is idling but it has no power.
You fix that and now it won't shift right because the clutch cylinders
are leaking. You get that fixed and the brakes leak. You can see that
this can be a large task. As for where to put it when it is finished,
that's easy. It goes on the DMCNEWS website under technical. Maybe the
way to do this would be to assign areas to different clubs and
technical advisors with some overlapping so everyone would be checking
on each other and you get the widest range of expertise. This is not a
one man project! To begin I would start with research into all the
previous posts and magazine articles.

Subject: Re: Engine Swap-Out

I disagree with the statement below.

$5K to get a extra 70HP out of a 20+ year old engine
is a awful lot of money.  My conversion will be
between 260-300HP, and (best I can tell at this point)
will be about the same cost.  When I am done, I will
have a modern technology engine with higher output and
better fuel economy than the PRV.  More importantly,
the ability to go to any junkyard or auto part store
to get parts for the engine.

I can guess that some may think "Yea, but your project
is not done!"  True, and in the end if it even works I
may blow my target price..  However, I believe the
documented Chevy V6 conversions have been under the
$5k price point.  This may have been Duke?

Subject: Re: Engine Swap-Out (Rice Burners)

Louie G and I ran into pack of rice burners at a fast food restaurant
on the way to SEDOC. Wings, gee whiz decals, the works. Met them again
on a Georgia interstate hill. Easily accelerated past. Never saw them
again after that.

Is a difference between HP and torque. Seem to remember someone once
told me HP measured at "top of the engine" and torque "at the bottom".
Think what they meant was torque translates into actual power
delivered to wheels. PRV has surprising bottom end grunt. Performance
certainly adequate off the line (is not going to embarass you at a
stop light). Where it really shines is under load. Do have to drop
back into 4th gear on really steep grades (overdrive gearing), but
it's steady 75 mph rest of the way to top.

Drive I-95 hills north of Richmond many times every year. Only
vehicles that can maintain speed are my old model Lincolns (of
course), SUV's, and the DeLorean. We play leap frog: rice burners etc
shoot past on the downhill side, then I overtake on the way back up.

Subject: Re: delorean power steering??

Don't know exactly how applicable old model full size Lincolns are, but:

My Mark V's handle very differently than DeLo. Is more than just girth
-- power steering translates into very different front wheel
movements. At speed LAST thing you want to do is rapidly move steering
wheel. A little dab'll do ya. When we went to Dave Swingle's mother's
house last spring had a copilot who drove part way (in Lincoln because
of broken arm). Reminded her not to move wheel more than 1/4
revolution, and slowly at that. Didn't want to flip the car at 80 mph.
Plus with power steering the only restraint is driver him/herself --
can spin steering as rapidly as you want with one finger, then suffer
consequences...

Really don't think you'd like a DeLo with power steering. Would make
things like Ken K's Dragon Run very difficult. Martin's correct: only
benefit is turning wheels while car stationary.

Subject: DeLorean model name...and other registration info

Hi,
What is the correct model name for the DeLorean?

I have found 2 variations:

* DeLorean DMC-12
* DeLorean LK Sport Coupé 
(what the heck does LK stand for?)

My registration document states: 

DeLorean DMC-12 / 2.8i V6

Does any of you have another model name stated in your registration document?

Also, my car is registered with a weight of 1280kg, with a max allowed total
weight of 1470.

Standard rims in front is 6" and rear is 8".
Min. load index in front is 75/H
Min. load index in front is 88/H
Noise level is 97db (at) 5500 rpm

Effect is 96kW
Ccm is 2849
Width is 185cm
Length is 427cm

All this according to the registration document.

Are there many variations from your registration documents? 

The problem, as I
see it, is that the DeLorean was never type approved in Europe (and in Norway),
so my guess is that there is lots of variations in each owner's registration
document.

Since the factory is no more, I'm interested in getting as accurate info as
possible to put into my registration document. So far my local traffic station
have been most helpful in changing "the little things" that were wrong to begin
with.

Now, I'd like feedback on ANYTHING that may be incorrect info in my registration document.

I assumed that it maybe electrical most if not all the fuel components have 
been cleaned, rebuilt or replaced in the last few two or three years. The car 
starts normal most of the time but once in a while it just won't start. If you 
turn and hold the key the engine will struggle, and if you pump the gas peddle 
it sometimes gives the engine a second long before it stalls. but if you turn 
the key then let the car sit for maybe 5min it will start right back up, and 
will be just a little shaky and will smooth out after an it runs for 15sec or 
so.

Subject: Re: Re: Engine Swap-Out

Hi Greg.  The previous responses have pretty well
covered the options available and highlighted the
renault tranny as the "weakest link" in any upgrade
plans.  I personally am finishing up the Eagle 3.0 PRV
conversion.  I'm using a '92 eagle 3.0 engine which
allowed me to: 1) retain the PRV "heritage" of the D
2) avoid any sort of adapter plates between the engine
and tranny and 3) maintain the Delorean's original
weight distribution and handling.  Some other benefits
that came along with the newer PRV were increased
displacement (to 3.0 liters), even-fire configuration,
increased compression ratio, electronic fuel injection
and serpentine belts.

In stock form, this engine won't put out as much power
as many of the other options, but for my project, I
placed a higher priority on the three items I listed
above.  As for power, I plan on a "phase 2" engine
where I'll do some of the typical power increasing
modifications (and I haven't ruled out a
supercharger).  My power goals however will not be
above the capabilities of the tranny.

You really have to determine what your goals are. Do
you just want more power?  Do you want electronic fuel
injection? etc. etc.  None of the conversions are easy
and none are cheap. Also consider how much can you do
yourself.  (Something as simple as fabricating an
alternator bracket can be costly if you have to have a
shop build it for you.)

Even though the engine I chose was a "bolt-in", I ran
into several fairly major problems during my
conversion.  I've covered these pretty well on my
website (www.projectdelorean.com), but feel free to
email me directly if you have any additional questions.

Has anyone ever cross-threaded their spark plugs?  What did you do to
remedy the situation?

Subject: running light failure

on my 81 vin 3543, the running lights on the driver's side (yellow 
light on front bumper, yellow light on front fender, red light on 
rear quarter panel, and center bulb on rear tail lamp assembly) will 
not come on.  in addition to that, the front blinker on driver's 
side works but does not stay on when the lights are turned on.  the 
passenger side lights work fine.  i have checked all the bulbs and 
cleaned all the terminals with no luck.  can anyone point me in the 
right direction to solve this problem.  

thanks for your help.

Subject: vacuum problem analysis please!

Hello List,

i have a number of tests completed now in my plea for help from the smart 
guys out there.

to recap:
my car has been tuned for the last three years with two things wrong - 

1) the vacuum hose that goes to the distributer advance diaphram was plugged 
into the MIDDLE connector on the advance solenoid.  this is wrong, it should 
have been plugged into the outer connector while the middle should go to the 
thermal control valve.  i don't know HOW I missed this in the past with all my 
work on the car......

2) that hose which was routed wrong had a BALL BEARING wedged into it to cut 
off vacuum to the advance diaphragm.  

I stumbled across the ball bearing while doing some other work on the car 
(cleaning the motor).  when i removed it, the idle increased to about 1000 and it 
ran rough.  here are the steps i have taken since then to try to rectify the 
problem.

1) found those two hoses to be routed incorrectly.  routed them the right way 
as well as verify correct routing of ALL hoses, including checking to see if 
hoses are on in the right manner on the thermal control valve.

2) checked timing as per shop manual with advance diaphragm hose disconnected 
and plugged from distributor with idle at 775.  timing on #6 cylinder 
indicates approximately 12 deg BTC with engine at approx 190 deg F engine temperature 
(according to book, there should be no advance right now when above 104 deg 
F).  HOWEVER, when i replace that hose onto the advance diaphragm, i can feel 
that there is vacuum on it (there shouldn't be) and it then shoots up the 
advance on the timing.  now with the timing wheel on my light at 0 (not showing 
advance) i can see the timing mark way up at like 50 deg BTC.  at this point, the 
car runs smoother and better (when advanced and at idle).

3) started inspecting WHY there is vacuum to the diaphragm when the car is 
hot.  checked the idle speed switch.  with a meter, i verified that with the car 
not running, the switch does indeed function when activated (checked ohms).  

4) started the engine and with it running and at idle, checked the voltage at 
the electrical connector on the side of the advance solenoid.  got a definite 
14.5 volts.  this should indicate that the idle speed switch is working 
correctly and it is tripped at the proper times.  this should also indicate that 
the advance solenoid, if it is not broken, should be energizing AND should not 
allow vacuum to the distributer advance diaphragm.  yet it DOES!  

what has me puzzled is that this would tend to indicate a broken advance 
solenoid.  however i replaced this part this summer already (and perhaps i was the 
one who routed those hoses backwards when installing it).  i suppose i COULD 
have a defective part, but i got it from Grady and it wasn't a used part.    

also note that when the car is running,  it tends to smooth out for a bit, 
then begin to surge a little, then smooth out, etc.  the exhaust is very rich, 
too.  sometimes when working over the engine it is enough to make your eyes 
water a little.  

what else should i check in order to rule out other possibilities?  the only 
conclusion i can come to is that the advance solenoid is broken, but it's hard 
to believe since it is a pretty new part.  any other ideas?  other tests of 
other parts to do?  certainly the problem (or at least A problem) is the 
presense of vacuum at the diaphragm even when the solenoid is receiving 14.5V from 
the idle microswitch.  what else could be at fault?

I am at a loss and would like to continue working on this over the weekend, 
so if you have a response, please CC it to my actual email address as well as 
to the list so i can get it right away.

Thanks in "advance" (heh heh)
Andy

Subject: delorean air conditioning question


I need some help with evacuating the air conditioning system.Does anyone know how many cfm to bring it down too? My pump can pull 5 cfm but im sure thats way more than necessary.Im not certified for  air conditioning work so I dont know.Can to much vacuum damage the deloreans ac system? It seems to much would cause the seals to fail.Isnt that correct? 

 

                                                 thanks guys

Sounds like the wires are crossed. It's not an even fire six 
cylinder. SB 1,6,3,5,2,4 - be sure you find number one cylinder. It 
is passenger side firewall cylider. Passenger side is 1,2,3 from the 
firewall.

haven't paid for, at least YET.  What could be causing this, sounds 
horrible and drives even worse?

Adam, Part of it is the old alternator, but most of it would be the grounds.

Subject: [DML] Power fluctuations, normal??


My car has had minor power fluctuations ever since I got it. For
example, the dash lights dim when the turn signal light is on.
Is this an old problem due to the stock alternators/voltage
regulators?

thanks, adam
