Saving another V8

Yes, all. My madness knows no bounds. A second V8 to join my stable soon.

It is a 3.6. 1991model. Similar spec to my 1990 model, but with some of the later updates- such as gas-dampers for the bootlid.
A photo shoot will have to happen before both head for extended storage- I'm either going away for work, or they will lock me up indefinitely.

HI,

great to hear! Can you provide some more details, color, interior, etc.?

Well, After a short while being too busy- the result is

A Metallic Black, 1991 3.6 V8. Overall, similar spec as my silver one-
Grey leather, memory heated seats.
Additionally, full remote alarm with closure function.

Generally, runs like a bag of nails. Bent and blunt nails at that.
Starts fine. Albeit after a couple of seconds cranking. battery is the wrong capacity too.
Running wise- it revs from idle, but does not sound clean.
In gear, it doesn't accelerate very well, and feels rough. At 3000rpm, it's fine, but still sluggish acceleration.
A clean up and check over of all of the sensors, rotors, plugs, leads is needed.

Fuel consumption is very high. 17mpg @ 60.

Brakes
Hmm. It does stop. Think Titanic...
Fairly sure one caliper is rather lazy.

Gearbox
Paperwork shows an expensive rebuild in it's life, but it doesn't shift as well as the other car. Sport mode doesn't function. (throttle switch/pot?) Used in manual selection releases a bit more of the hidden horsepower (not so much horse power as 3-legged donkey power)

The shift selector is the later version that won't release the key unless it's in park. That works. However, it doesn't always indicate 'P', so starting has to be done in Neutral sometimes. I presume adjustment is required.

It needs a good cleanup, but otherwise is solid.
Ride is fine, currently running on 17inch A8 alloys

I've also acquired the camshaft alignment tools, a complete new undertray.

So, all in all, the verdict is-

I'm utterly insane!

Mark,

you're _indeed_ insane? Don't want alter '93 or don't they come by any more in the UK?

I would check the engine timing, maybe it's off a bit, could be a reason for the poor acc.

Pictures, Sir?

Regards and happy to have at least one addict in the kingdom

I keep promising pictures, but never get around to it. So I won't promise.

Both cars are full of junk, and look tatty right now.

Timing. I shall take a look at it in due course. It almost feels as if it is firing on 7, not 8.
Much work to do.
The headlining in the new car is hanging low at the back. Just the material cover. Flapping loose.

As for later cars. I looked at a Ragusa green, 4.2. Described as being in pretty good condition.

I fixed or diagnosed half the instruments in the process of looking it over. Just to determine if it had any oil pressure. It was actually oil tight.
But the car was falling apart, and needed a full strip to bare shell. The paint looked like someone had started rubbing it down, already.
He wanted double it's worth, and wouldn't sell to me. Fair enough. I think it's been sold and broken now.

Worst case, burnd exaust valve.

At some stage in the past, the heads have been rebuilt, new seals, gaskets. Documented. I think in the main, it has just sat neglected for too long.

I'm an optimist.

Ok, but you still do not know what the preowner hat done with the car.
maybe it runs with new sparkplugs, ignition wires, caps and distributors fine again or worst case szenario.

Indeed.
I start tackling it in earnest, tomorrow. A number of items to attack. Already, it's driving a little better. It's a little touchy when the connections to the idle stabiliser is wiggled.
The air temp sensor connections are looking a little ropey, and I'm sure there's something lurking in the plug to the throttle pot/switches.

For starters.

At least the handbrake works! But then, at present, only gravity has a chance of overcoming it. Engine power is currently insufficient.

Some of it, I already knew about, but had forgotten. Like the air temp sensor wiring.
Some of it has become more apparent as I have been fiddling.

The problem with working away from home a lot, is not having the kit and space that is normally available. So it's a check and make do, mostly.
I can see the Audi Workshop manual being put to some use.

In the very near future, I shall be changing over the brakes, as with the silver car.

Choices are-
HP2/S6 struts as before. Very easy to do, with minimal workshop space. The last set, I obtained for £200, Brakes, struts, disks, pads complete. This is preferred for now, as it would keep commonality with the 2 cars. A bit rare over here.

Or

Porsche calipers. 993s can be found for sensible money, work with the S6/A8(et al) discs. So I would just need mounting brackets.
Or, the uber sexy 6pot caliper, from the larger machines in VAG group.

I would take the easier way with the HP2 Brakes, for 200GBP is very cheap.
My HP2 had cost years ago approx. 400€ with out disks and pads.

A with all things, first things first.
The car was running on 7 cylinders, sometimes only 6.

A dodgy HT lead- very expensive 10mm custom leads, but badly assembled. So the spark was breaking down to #4. More curious is #8- it doesn't appear to be getting any fuel.
So, time to make another codes lead.

But, currently, it's running so much better, with improved fuel consumption. So, it's going in the right direction.

The throttle pot/switch is an issue- or rather, the completely messed up wiring, which has 5 soldered repairs. Not good ones either.

New fault found.
Dodgy connection to the switch at the top of the steering rack. Fixed that, now have Hydraulic system warning on the instruments.

And currently, there is no signal to front left indicator, and is proving a sod to find.

Oh my God.....
Thats why the preownder sold the car,
he messed up more than he fixed well.
