 |
|
Hello!
We recently got a Porsche 924 from 1979 that have stood still for over 10 years and the plan is to bring it back to life.
We plan to take out the engine and renovate it, heard that the valve springs are a good thing to change after all those years?
The chassis has some corrosion but nothing severe. It is hard to push the car, the front disc brakes look really corroded.
One thing that's strange is that the brake pedal goes all the way to the floor and it doesn't brake. The brake fluid reservoir is full.
It would be great to hear some tips of what we should check/replace after 10 years of being still.

| I suggest you read all my posts. My car was sitting for 10 years also. But I suspect yours is worse then mine was. |

Can you outline what stands out as to your first impressions of the car? For example, air sensor plate movement, appearance of spark plugs, deposits in fuel tank checked by pulling the in-tank pump, how the engine turns over by hand, what the coolant looks like, estimates of compression, and so forth. |

Hello, and welcome Tanso, member # 5550
On here you'll find over 310749 +1… articles that you'll have to navigate through:
Search is your friend: Read the How-To so you can use it in G00gle (better results).
http://www.924board.org/viewtopic.php?t=33395
But, even before that, read the FAQ at 924.org so you get the basics?
Oh, and posting pics can be helpfull How to post pics on this board
Furthermore …CIS
CIS, CIS, CIS… can't say it enough
All CIS is is the Bosch K-jetronic 'Continuous Injection System'
It needs cleaning from tank to injector, especially the WUR/fuel pressure…
Clean it all, read the PDF's, get to know the system, don't do half work,
ask twice to get it right …or maybe it won't run, sadly
So, does the project, your car have a name?

| Wikipedia: Brake Fluid > > wrote: | | brake fluids are hygroscopic (water absorbing), which means they absorb moisture from the atmosphere under normal humidity ... |
So, overtime brake fluid collects moisture …in those 10 years it could have become too much!
Now the water responds to cold (–°C) and before you know it the Brake Master Cilinder needs a rebuild (seals).
You'll find several reports in the past around here that show resamblence.
Replace the brake fluid every 3 or 4 years as a preventative measure to avoid damage to the BMC.
Good luck!
Harm.

| The brake pressure issue is the master cylinder. The seals go bad from sitting, its a common problem for a lot of cars that sit. I wouldn't use a m/c that sat for that long anyway. Replace all the hoses for the brakes and clutch as well as rebuilding the calipers. Nothing is more important than being able to stop. |

Really great tips!
These are the tips I got so far.
1. The CIS needs a total cleaning from tank to injector.
2. Check the brake master cylinder and rebuild seals if necessary.
3. Replace hoses for brake and clutch. Change brake fluid.
4. Rebuild brake calipers.
On saturday we are hoping to get the engine out. Today we purchased a used engine lift and stand for a good price. What more than the valve springs should we check and replace when we have the engine out?
Here are some pictures:

Not bad. There is some patina but for example the dashboard is in great shape!

Yes I believe that the dashboard has not been affected by the sun in the garage

Car looks like a good starting point for sure. It almost looks like it has the white from the Sebring edition cars. What do the seats look like, i couldn't make out the pattern.
Good luck with the build.

Looks good....not sure I'd take the engine out w/o checking out everything first. You might be surprised and have yourself a running car with not much effort. Engines are tough, fuel system is the downfall of sitting up....

Yes, I also was surprised Tanso et al. were pulling the engine.
Perhaps, the PO had had problems which necessitated removal; otherwise, to me, the prudent thing to do would have been
to re-build the fuel system, verify the ignition system, and see what needs to be done from there. |

Maybe the engine might run as it is now but we want to inspect the engine from the inside and don't want to destroy anything unnecessarily.
We are going to skim the head and fit the Porsche 924 turbo head gasket, read on 924.org that it will raise the compression. Anybody here done it?
We have never worked with this type of engine before and we have never removed the engine from a car before either. But we are doing it for fun and learning also.
On saturday we hope to begin the process if the weather are with us.

looks better than mine did. there was no brake fluid in mine at all. when I took it home, and rolled it down the driveway. I was halfway into the garage, when I realized that the brake pedal went ALL the way to the floor with nothing happening. lucky for me (and the garage) the motor was seized, because I jammed it in gear, and it skidded to a stop.  make sure to check the rings, because all mine were gunked up, and wouldn't hold compression. plus the blown head gasket. and the electrical which I am working on now. and the cis, which thankfully I cleaned before trying to start. It looked like coffee coming out of the tank.  |
