84 4KQ Susp. Clunk & Power questions
My '84 4KQ is clunking in the rear suspension. It is constant, and seems
to happen most when running over bumps, but also happens when
power is being transferred, such as when the drivetrain undergoes a
torque reversal.
I have had the rear A-arm bushings replaced recently, and the diff mounts
<look> OK. I am wondering if this could be caused by the rear strut
bearings going south?
Also, is it possible to swap the camshaft on this engine for one of the
later model 5-cylinders for the extra horsepower? If so, does anyone have
an idea of where to get one?
Thanks for any help!

Hi,
I just got this address for quattro owners and thought I would
just send a short note.
I just bought a 1986 5000 Quattro S/W Turbo and will be looking
for information about it in the near future.
Is there a Home page or any other address to look for for info or
how do we go about finding info.
I've always been a VW fan and so far quite happy with my
purchase.
I am located in Calgary, Canada.
Thank you,
Jean Pichette

I'm sorry if this posts twice but i got a strange error message after i
tried the first time.
I need to change my speedometer. I have a used instrument panel i'm
replacing the old one with. It is an 85 5ks. Do i need to remove the
steering wheel to pull the unit out? I pulled off the horn cover
(centerpiece) and saw nothing but possibly a small screw behind the horn
with a small hole to access it. The lighting was poor so i don't even
know if there is a screw there. Could someone please help me out here?
I hate trying something without knowing and screwing it up. Thanks...

Subject: Re: Reverse problems
Bruce,
Something that my dad and I just figured out after we replaced the
automatic in my '86 5000CS Turbo with a 5spd, that the mechanic that
acutally changed the transmissions out, decided to put the 5spd in there
with some defective and old parts from the other car that the old trannie
came out of. The part that I am referring to, which is the same as in
your '89 I think, is the ball and socket joint that connects to the
from the linkage to the actually trannie. If this part and the other two
ball and socket joints that are right near by, one for one of the rods
and another for the other plus a adjusting rod that has two joints as
well, are not in very good solid shape, it will cause weird things to
happen to your shifter. Check your manual to see what I am talking
about. This might help but maybe not, it's just a thought.
Karl.

Subject: UFO brakes (WAS: Insurance Bashing)
UFO brakes are a nickname given to the internal caliper brakes used by
Audi on the 91 200 quattro *wagon* (not on the sedan) and on the early
nineties V8s. Audi figured they could better braking by increasing the
swept area of the front brakes. To do this without putting bigger wheels
on the cars, they figured out a way to mount the calipers on the inside
of the rotor, thus being able to extend the rotor all the way to the
inside edge of the wheel. This has been leading to some cooling and
other problems that make the rotors warp very, very quickly (sometimes
when the cars came off the truck, I've been told at the dealer).
Audi switched to using some new material in the rotors sometime in 92 (I
think) and is still using remanufactured rotors as new rotors are hugely
expensive. The remanufactured ones ain't cheap either, but it's
better...
Look for a cage like structure around the front brakes, visible through
the wheels, to see if a car has UFO brakes. They're not necessarily a
lot of trouble, but the potential is there...

I am putting it into an ur-q, so I guess I have some advantage here, I know
it all fits.

I have had my swap in the works for 9 mos now and just getting back into
it. I spent 6 hours on saturday buzzing out the left and right side
harnesses
from my donor 89. At this point I am figuring out what I need to use from
the
old harness and how and where to make the break.
I went for the complete engine including all the sensors and misc stuff
including idle stab. I also have the carbon canister, O2 frequency valve,
wastegate frequency valve. Don't have a deceleration fuel cut-off valve,
not sure it is really needed. I also grabbed the all the fuel system stuff,
fuel distributor, injector lines, injectors and control pressure regulator.
Be sure to get the whole ECU to engine wiring harness and ECU. It's
also nice to get the the engine harness from the left side of the car
although
you can fab what you need here. Be sure to grab the coil and its booster.
Don't forget the knock sensor, RPM sensor, ref mark sensor, especialy
the mount blocks. Also get the distibutor amd hall sensor. Grab the
flywheel and clutch/pressure plate too. The list just goes on and on and
on...
The turbo uses the WOT and idle switches too, just packaged differently.
For my swap, I learned of a mid 80s Audi application which has seperate
WOT and idle switches, kinda like the ur-q setup, but goes into the
integrated
3 wire connector. This will then plug right into the late model harness. I
am
using the stock ur-q throttle body and a 5000 turbo intake manifold from,
I think 84. This guy is nice because it doesn't have the idle air bypass
tube
built into manifold on the 86 and later cars and the early throttle body
works
with it. Also it has a mounting boss on the side of the manifold for the air
temp
sensor, whereas the later 5kT cars have the air temp sensor in the
intercooler.
I don't think I will be using the aux turbo coolant pump. I would get these
parts,
in case you decide to plumb it in.
>Also. Remember the $10 turbo I took out of the junkyard off the 5kt? It
>was a K26. Not water cooled. Well, the one in this car is water cooled,

Go with the water cooled one. The 5kT cars made the change somewhere
in 84/85, but before 86. Yup they're both K26s.
>Anyone done this job before? If so, let me know!! OTherwise, Ill keep you
>all posted!
Well I am up to my chin right now, changed out the front crank seal
yesterday and will be installing the tweaked turbo this week. Then its
flywheel/clutch/engine/tranny assembly time. The fun has just begun.
Any questions, ask away!

Subject: Radiator: Repair vs. Replace, Plastic vs. Metal
Hi all. Was replacing the rad fan on my 5kS a few days ago, and
happened to notice that the rad was leaking. Seems to be at the
junction between the plastic end cap and the Al core. Went back
about a year in the archives, and found some discussion on the
topic, but didn't find any real consensus on the issue, so I
figured it might be worth revisiting...
Here's a list of the pros and cons I've come up with so far:
Pro Con
- ----------------------------------------------------------
Repair cheap expensive (when it breaks unexpectedly)
core deposits (unless cleaned)
Replace longevity $$$
no deposits
Plastic originality somewhat fragile
lightweight
Metal higher thermal K heavy
(only if copper)
more durable ??
Currently, I'm leaning toward replacement with an OEM unit.
Thoughts anyone?

Yes, it blows air over the injectors. Should help prevent air in fuel
lines I guess. Don't know exactly at what times its
supposed to operate though.
What was your hot start problem? Most often the case is bad fuel check
valve or leaky injectors.

You need a lot of patience and in some cases special tools to use the
Bentley manual. Some mechanical ability wouldn't hurt either. I don't know
how the thread on engine related error codes got mixed up with the climate
control panel error codes. The climate control system has it's own
diagnosis system with code reading and all. Does not always prove helpful.
The error codes for the engine are completely different and are read by
inserting a fuse in the fuel pump relay and watching the engine check
light. This again is not always very helpful.

It's to cool the injectors to prevent vaporlock and might also improve =

"Uh, no, I've got the 10 valve turbo motor."
"Oh, we don't sell modifications for the 10 valve motor."
