Posted: Thu Aug 07, 2025 6:53 am Post subject: Awakening an 82 924 that hasn't run in over a year (minimum) |
|
|
Hi everyone, I've possibly made the dumbest decision of my life and finally bought a project car. After digging in the depths of the forum for the past two days while waiting to be accepted, I have compiled my first chunk of questions.
I have acquired a 1982 924 2.0 with the Audi engine. She runs and drives, but has a busted front driver side (LHD) brake line that seems to be unavailable now.... anybody know where I could find those lines? There's also some fluid on the front of the brake booster, what could I be getting into here?
Additionally, she seems to be missing some pieces that connect to the fan or radiator that I can't tell what's missing based on the parts diagrams. There's a tube covered in tinfoil (assumably cracked thus the tinfoil) to the left of where the hood latches and whatever connects is gone. What is that?
Whoever was in here before me also did some backyard wiring for the fuel pump and the lights (and a lot of the engine bay yay). When the fuel pump turns on it buzzes LOUD. It's a bosch pump from what I can tell, but I don't know whether to be concerned about the buzz or not as I use it to know its on atm.
She also has a sloppy shifter and reverse is a PITA to get into. Is that just going to be linkages and bushings? Or am I in for a world of "fun"?
I'm sorry for all the questions, I know I will have a lot more over the next few months. TYSMIA!!!
*small edit: after digging through the small box of goodies that was included with the car I have found a shifter that's missing hardware from only944.com, a drum brake wheel cylinder from Dorman, and a headlight cover. _________________ Just trying my best to figure this out without total failure

On the brake line, if it's the hard line, it shouldn't be too difficult to get some hard line, bend it, and have the ends terminated to match. As I recall, both ends are a flare fitting, but also metric, so that might be a wrinkle. I'd take pictures of the ends, take the brake line off, as well as the fittings or hose at either end, and take it to a brake shop (or at least measure how long it is). The should be able to sell you some hard line and match the flare and fittings. I can't say I've personally done that; I've only replaced pre-made hard lines. That said, I think a good brake shop should be able to figure it out. I was able to buy new flex lines with no issues, so keep looking if that's the issue.
Some pictures of the fan and radiator area would be helpful, but there's nothing too complicated about the setup. The wiring could be a pain; I'd wonder why the PO meddled there. The fuel pumps on these is more noticeable than most cars - I think due to the pump being external. I can hear mine pretty plainly with the engine not running, but it's not so loud that it stands out with the engine running. My experience with Bosch pumps is they either lock up from sitting, or start leaking; I've never had one just quit working on a car being driven. So unless it's still an obvious sound over the engine, I'm not sure there's anything wrong. I'm not familiar with the shifter on the Audi transaxle you've got, but I think it's going to be the same thing as most shifter issues: blown bushings. You can get to the ones at the shift lever side pretty easily, but the ones at the transmission end are a big job to get to. I was going to tackle mine when I first got the car going, but the whole transmission needs to be rebuilt, and I've found I can work around the sloppiness.
Anyway, good luck with it! I've found a lot of answers searching around here; sometimes that's the quickest way, but you'll definitely run into things worth sounding off here. _________________ 1980 931 diamond in the rough |

Thank you!! Here's a link to my google drive that I'm building as the project goes along, I haven't figured out how to embed a photo in here yet, but that's the mystery tinfoil tube. https://drive.google.com/drive/folders/1C90KRI_WBfL3f8z8NIg2WlteMujj7h4O?usp=sharing And okay cool, I can't notice the fuel pump once the engine is running so that makes me feel a bit better about the loudness.
I have ordered the hardware for the shifter arm, a shifter linkage arm, and I'm trying to figure out what other bushings I'll need for in there. I also found my sacrificial 11mm because I'm going to try my hardest to not drop the trans. _________________ Just trying my best to figure this out without total failure

https://drive.google.com/drive/folders/1C90KRI_WBfL3f8z8NIg2WlteMujj7h4O?usp=sharing Here's the mystery tube, it would make sense if its the alternator air duct as there's a tube in the depths on what looks like could be the alternator. Would you happen to know the part numbers for whatever's missing and the upper ducting? I've been staring at part diagrams of the cooling systems and fans but I'm not sure what tube is what in there since I'm missing something and potentially other things. _________________ Just trying my best to figure this out without total failure

Update: I finally found the mystery tinfoil tube part number. It is indeed the connection piece for the alternator. Literally called "connection piece" in the parts manual......so helpful Porsche. But PN #047903199, after more digging by part number I stumbled across this post on here I somehow didn't find previously https://www.924board.org/viewtopic.php?p=415176&sid=6125b450e49026821fa21dbf1d23ff58 which led me to an STL file for the part if I can't source it locally, which it seems like is near impossible based on further research.
How important is tinfoil tube (that's what I've decided to call it)? Further digging has left me with a 50/50 consensus. Half say I need it to not fry my alternator with heat and the other half say their car never had it and work perfectly fine.
My main goal with Poppy rn is to get her fully functional and back to operational reliably. Trying to figure out my plan of attack here as I'm balling on a college kid budget and trying to determine important must-dos _________________ Just trying my best to figure this out without total failure

I'd look into alternatives, like you might be able to find some kind of flexible dryer duct or something along those lines at a hardware store. Definitely make sure it's not able to flop around and come off; some big hose clamps might even be able to crush down a significantly bigger piece of hose and hold it on. I've got a 931, which has the alternator mounted up high with no cooling duct, so I can't speak much to the ducting situation. As long as you're not dealing with pretty hot temps and/or mostly stop-and-go driving, you might get away with it for a while or indefinitely. Another approach would be to dig up a spare alternator (probably used, but make sure it works), and drive it until the one that's on it dies (or doesn't). You know they wouldn't put it on there unless there was some need for it, but it's hard to say what triggers that need. _________________ 1980 931 diamond in the rough |

Thanks Beartooth, I am still debating on what to do with the tinfoil tube and the cooling tube. I think I am going to try and source a new tinfoil tube via 3d print and connect a tube of some sort on there and go with it, but that will be lower on my list of to-dos.
I'll be making a new thread as I found some more "fun" in the engine bay and the po's redneck wiring job has spread further than originally thought. yay. _________________ Just trying my best to figure this out without total failure

The tube for the alternator is pretty standard 50mm heater tube. Bought it on aliexpress for a couple of bucks. |

Awesome thank you so much, do you happen to know the length I need? _________________ Just trying my best to figure this out without total failure

Not exactly, but I'm quite sure it's shorter than a meter. |

Hello, welcome to the board!!
As for the shifter linkage.Sometimes it helps to disconnect the linkage inside of the car and reinstall it with 180° deg.offset.That fixed my shifter problem 30 years ago.....Sometimes it is the lever itself that has been worn over the decades.

Thanks Riggard and Nobbi! I'll see what happens when I throw in the new hardware for the shifter and linkage arm and hopefully that cleans it up. I'm guessing I'll also probably need the little plastic/rubber bearing shell (PN 94442423101) for the new shifter arm to sit in? _________________ Just trying my best to figure this out without total failure

Reverse has no synchro on 924, this is somewhat standard behaviour I think. Unless it seems PITA beyond what would be justified by having no synchro then you don't need to chase that particular problem. |
