 |
|
Iam about to become a proud owner of a 1977 924. The car iam about to buy has been sitting for 8 years now, it has a problem with the injection and needs some work to make it go. Dont know what has become plugged in there yet. It will fire up with some strating fluid, but isnt enought to see how it runs. The odometer reads 94ooo miles, and the guy says its the original and not rolled over mlg. I dont really buy it thoug, but the interior is almost mint (one seat has two small craks on the bottom, and the rest is just mint). No dents or holes, just small surface rust the windshield, etc. It has been repainted and will look good with some work. The motor looks pretty clean inside.
AT this point Iam confused about the real mlg of the car, since it was once imported form montana 17 years ago and has not been driven for 8 years.
Is there any certain part of the car that could reveal its true mileage in terms of wear or grime or oxidation ?
P. S. The car is dirt cheap, but I havent made sure yet the motor doesnt need a rebuild or the clutch needs replacing. |

Welcome to the board!!
As you consider buying this car, consider that I estimate that it may take a couple of thousand dollars to return it to safe running condition.

| A good (and easy) method of guestimating mileage is by looking at the wear on the brake and clutch pedals. |

The pedals look good. And the the condition of the vehicle is fairly nice, considering the interior and the repaint. All the other cars this vintage that I have looked at usually have visible holes in the rockers and floors, even newer ones, but this one has all the panels straight and practiclly only a few minor rust spots that I could even fix em myself. The guy says the day he parked it it was running fine and trany shifted nicely. The motor starts up just fine, but I think the right motor mount is broken. Iam going there one more time to do a comp test and see if i could run the motor for a little longer.
The thing is that where I live its really hard to find a project that has a nice interior and good body like this.
I was wondering if those leather seats would show the mileage of the car or maybe the sloppyness of the shifter or something like that?
This car has either just 94XXX miles or 194XXX miles. What would a 924 look like if it had 194k on it? I think most of the compenents would be toasted! And this guy has not done anything to the car in 17 years, not even the water pump? Maybe, its just too good to be true. The guy paid $5000 for it in 1989. |

the car will need the entire fuel system to be taken out and cleaned, including the fuel tank.

The dude did it last year. Since then the gas went bad again. No sure how much rust is in there. But I can tell he worked on this and most of the components were taken off, but not put together properly. The thing is that something happened to it during his "once a month" start up, so he never boethered to fix it til now. My first guess is that this is the WUR, cause it starts but fails to run.
I was thinking of swithcing to a carb. Which car do I get an Audi/VW manifold like this? |

Welcome to the board. Where are you located? There maybe someone in your area that can take a look at it for you/ with you and help you decide before you buy.
The early cars didn't have the galvanized body so rust can really cause you problems, especially around the windshield, sunroof and rockers. You can easily get into some serious money just on the body work, before you even attack the running issues. No such thing as a "cheap Porsche". 
Try to find a Haynes manual first (I think there's a link on this board) and read up on the CIS. A non-running 924 can have a myriad of problems as the cause and one that's been sitting this long will need, as already mentioned, a complete fuel system cleaning, including the removal of the fuel tank.
You may, depending on your location, be able to find a running example in your area that would be less money to ressurect. Either way, you'll have a good time, I'm sure.
Read the FAQ on this board. It will answer alot of your questions. The carb conversion can actually decrease the engine output on an already anemic little car. But lots of people have done it. Personally, I think the CIS is pretty simple to work on and not hard to fix, once you learn how they work.
Good luck!

Once you get your CIS fuel injection system sorted out, which is NOT technically difficult to fix, BUT can be hard to understand. You will never want to drive a carb engine again.
A car with CIS working properly, starts first time every time, runs smooth from start up, has amazing fuel economy, and never misses a beat, mile after mile.
Good second hand parts for your CIS, are plentiful, most of the board members are experts on the system, you will probablyy find it easier and cheaper to get your CIS system working WITHOUT carbs.
Carbs suck ! literally  |

| I dont have anything against carbs, hence Iam used to vintage BMWs. I worked on the injection a few times myself, but the whole idea about cleaning this whole thing up and then adjusting it kinda makes me wanna get rid of it. |

If you put carbs on, you'd still have to clean the fuel tank. That's probably the hardest part of getting the system back into working order. Clean the tank, check the pumps for debris blockage, change the filter, put a liner in the tank while you've got it out, pump some techron through the lines toclean them and soak into the fuel distributor, change the injectors or have them cleaned, change the rubber seats for the injectors (dried out they'll cause vaccuum leaks) and your pretty much set. If no one's been jacking with the mixture before you got it, you shouldn't need to do much adjusting. Probably want to replace the WUR, clean the cold start valve and test it and the auxillary air valve for correct operation. Not too much more to it.
Are you in a witness protection program? Is that why you can't reveal your location?

Well, the mechanicals are probably the easiest thing to deal with. Having a sound body and interior is a major plus, in my opinion. But don't skip the detail, check thoroughly for minor/major accident repair if it's been repainted...
The engines in these cars are simple and easy to work on... and pretty damn cheap, relatively speaking. Parts are generally easy to source, too (if you're in or near Big City, North America).
That being said, I agree with Paul, don't think it's only gonna cost twenty bucks at the local auto shop to restore it to good health! On the plus side, it isn't gonna cost twenty-thousand bucks, either (unless you want it to  ).

I'm of the opinion, with a car this age, it really doesn't matter how many miles are on it. If it's structurally sound and the interior is good, then there's a better than average chance it's had a good life.
I guess the major difference between 94k miles and 194k miles is whether you might be up for a complete driveline rebuild in the near future (including the engine, clutch, gearbox, brakes, etc). Unfortunately, unless you really know a thing or two about cars and can give it a thorough inspection, the only real way to be sure is to get it running and take it for a good, long drive (catch-22, eh?)
Is the engine and engine bay relatively clean? I mean, after sitting for eight years it's probably a bit dirty and dusty. But is it relatively clean, no major corrosion anywhere or dirty, thick, oily sludge all over it? If it's relatively clean, that's another sign that it's had a good life. Same goes for the rest of the driveline and brakes, etc.
In the end it's up to you. Can you afford or would be willing to drop a few thousand bucks into it if you had to? If not, walk away...
