New To Porsche - 928S...The Questions begin.
Discussion
Hi all,
I'm new to Porsce and have recently bought myself a non-running 928S, which I will have on my drive on Friday.
I've found various links etc by searching previous posts which is giving me loads to read about.
However, first things first. What shoudl I be looking for on a car that has been stood for a while? i.e. which bits will almost certainly be screwed?
Secondly, Where are the real rust spots on the car to look for? Unless I'm mad, I believe the bodywork is all aluminium, so corrosion shouldn't be a problem there, but I'm sure there must be other parts I should be looking at?
Any help appreciated and I'm hoping to set up a bit of a web page as I start stripping her down and restoring her.
I'm completely new to Porsche and the 928, so anything you can tell me, no matter how obvious to you it sounds, would be appreciated!
Thanks
JC

Bodywork is not aluminium, but it is galvanised steel IIRC.... non-running 928... your a brave man!
Thanks for confirming I'm completely mad....
I needed something to get my teeth into, and the best way to learn something is to do it.... I think...
In the end, it should be an experience. Good to know, I'm wrong about my first assumption though... always encouraging!!

if its not a stupid question, do you know what's causing it not to run ?
Apparently, it will idle all o.k. but as soo as you start to apply any gas, it dies.
I can't quote off hand but I've found a few occurances of this on the web, and they see to point to some sort of regulator (I have the exact name somewhere) That will be my first port of call, once I've satisfied myself that all the normal combustion processes are happy.
The PO had his own take on what was wrong with it too, something to do with airflow....
I think I need to get it in the garage and just start from the bottom and work up. I don't think it's going to be an easy project, but I have an empty garage and I need something to keep me out of trouble.
cool, very best of luck, lovely cars. I think there's a site, might be called www.928.org which may be useful (could be wrong about the address though)
Congratulations and good luck John!
What sort of 928 is it? I've got a non running '81 928S Auto which had exactly the same problem you described, so do let me know the root cause when you find out!
Cheburator knows a guy who specialises in 928s and is good for cheap spares apparently?

Congrats on your '83 928. If you are in UK your spec may be different from mine, but my US spec '83 was the fastest car sold in North America that year. It is an "S" car, with 4.7 liter motor. Mine is a 5-speed (I have two 944's too, one being a S2 cab).
The 928 most certainly does use aluminum body work, the front hood and doors are aluminum, but the rest of the body is galvanized steel or plastic (front and rear bumpers). Check it out with a magnet, you'll see.
If the car starts and idles, you have most of the battle already won, I would think. Check the relays, they are notorious for malfunctioning on a car that old. Change out the relay that controls the EFI, because if it isn't already gone, it will be soon.
Also, you may look at the Temp II sensor, the Thermo Time Switch, both of which are up front on the motor and easy to get to. The latter controls the cold start valve, which is waaaay under that spider intake. Of course, it could be the CSV too. If your car is a Euro-spec, then these things may be a bit different, as the Euro is more car (more horsepower) than mine.
In any case, I would start with the replacement of the relays, because I had one fail, took it apart, and was surprised to see a mild frosting of corrosion all over the light copper wire wrapping around the internals. They sometimes die slowly.
BY ALL MEANS............DO NOT neglect the timing belt. If it has been sitting a long time, or if it has 40,000 or 50,000 miles on it, you better have it replaced in the name of good preventative maintenance. Otherwise, you might be one to hear that rare sound of popping 928 valves, ouch!!!!
If you have any specifics, I'd be glad to reference info to you, and you're welcome to PM me on my email directly if you want.
Here's a tip on your car. If it idles, and wants to stall when you give it the gas, go ahead and let it idle and get up to operating temp. Keep trying to blip the throttle to see if it breaks out of the stalling it's trying to do. Mine did EXACTLY the same thing, but all of a sudden when it warmed up, it all of a sudden ran just perfectly. It turned out to be the Thermo time switch, located on the starboard side of the motor, at the front where the radiator hose joins the motor.
Regards and good luck, when these things are running they will put a smile on anyone's face. Many times the difficulty with the motor can be traced to VERY simple things, as these motors have no real weakness.

Here's something for inspiration. Turn your speakers up!
(this is the 928 racing video I recently posted, in case you have already seen it....showing me on my way to work in the morning, ha ha.....just joking)
www.jeepvideos.com/mpeg/031122sp-traffic.mpg
Notice how the 911 is running in the video, and how it avoids sliding off the track backwards. :-)
