Looks like the car took a hard hit back when the fender got wonked.
An entire chunk of engine, including all of the lower A/C mounts, has been welded back on.
I doubt that AC and block damage was from the fender being hit - much more common to see that kind of cracking on a car that's had a high-speed collision with a sleeping policeman, or possibly just a kerb.

The knock sensor and ABS harness covers are normal - check the rear ABS harnesses too, especially the driver's side, as they can probably use some repair with self-amalgamating rubber tape.

Looking at your interior, your seats are in excellent condition so even if not accurate, the mileage is still likely under 100k. Looks like your dash AC temp sensor vent is still complete too which is a good sign.

Did you figure out yet whether your car is late enough '88 to get the high-compression piston design?

Is this a quiz? Or is there an easy way to tell? (Pant, pant, pant)

what is the VIN or engine serial number is what he is asking.

It is likely to be the early S4 which is slightly lower CR (9.3vs 10:1)

Reckon I can use 89 octane, though.

The right (small) resonator is bashed up too.
I will probably get a set of '87/GTS big resonators for use with an X-pipe, anyway.


OK. I guess I'll calm down, now.
The rear ABS harnesses do need recovering.


The A/C sampler cover is from Nicole.

That crank gear looks pretty chewed up. And it has a Gates racing belt?

Ken, if you decide you'd rather outfit that car with an 86.5 block and computers, instead of that quirky S-4 setup, let me know.

Ha! I keep looking at the engine and thinking I forgot to put the side plenums on. (Seriously. )

I think that's water and a trick of the flash.
The gear is nice, with no 'lip' at the back.
The 'racing' belt was only on there for ~130 miles.

Don't see any blue on the timing belt and what makes the water pump bad? From the looks of the block face where the pump impeller sets,you have other issues.

Ed - the impeller assembly spins independent of the pulley. 138 miles on the belt/pump.

I think it boiled over, plain water was put in for further testing.
The metal impeller sat in plain water for a while, post failure.
Hence the rust stains.

The block face is smooth, with no scoring I can feel.
(There were no foreign objects present when I pulled it.)


I refitted the pump, without bolts, sans gasket; the impeller section spins without binding.



I'm sending the pump back to the PO.
I will take more photos of the block.
Y'all can work out the details.

Ok, good to know. The more info and facts we have the better for future development.
So, what makes the pump "bad"?

The pump does not.

Poor word choice, perhaps.

As a 'professional courtesy', and the fact it was not done on my watch, I wasn't going to mention it was yours.




Colin brought it up.

Colin brought it up.
Right, and the bright blue belt comment was Colin's idea also?
I do agree a bad choice of words.
"If" one of my pumps was on there and "if" there was a problem between the pulley and the impeller shaft, maybe it would be a good idea to find out why it doesn't pump,instead of just saying its "bad" because it doesn't pump.

Ed - you've developed a word sensitivity, me thinks. (I know the feeling.)

'Super dark blue', as in black, because the Gates Racing belt is usually blue on other applications, AFAIK.

I used the word 'bad' in the typical automotive vernacular to describe the part's function, not the literal meaning: "inadequate or below standard; not satisfactory for use" to describe the part itself.

So if the belt driving the pump is not capable of turning the pump,in which case causes the pump not to pump, the pump is bad. Got it! Comon!.
By the way, proffessional courtesy would have been a phone call, e-mail, pm. Just sayin'.
I may have been sensitive on the blue word as I have gotten jabbed about the paint before and will plate the next batch. Hopefully the color plating will be acceptable.
It is curious though,how someone not involved in the car for some reason had the need to mention that the pump was alledgedly one of mine and it should be checked, and in doing so you say it is bad but are unable or unwilling to explain why it is bad and not being used.
Since you are the owner of the car and the pump, that is alledgedly mine, why haven't you contacted me about it, as a professional courtesy, to help in getting it back to me to find out what,if anything, could be wrong with it and maybe be able to fix a possible problem or condition that could affect other owners who have the pump installed?
