Evening all, I’m after a bit of advice please .
I’ve recently won at auction a UK 1980 Porsche 928 4.5l
the car has been stored since 1996 and not turned a wheel, I think it was stored without fuel and coolant.
ive (my mechanic friend) has done a leak down test and compression test etc. these resulted in psi ranged on cylinders of between 180 and 190 psi. All went so well that we tried starting it (after other tests ) and it runs really nicely on the lift in neutral, although it could do with better fuel and service bits.

now I want to do things right, although it had a service before it was layed up (at 78k). And I think a cam belt etc, I think after 28 years stuff will need changing - including the 1994 Pirelli P6 tyres.

so, I’ll start, but if other can add things please that will be great.

I’ll check the discs, callipers and pads and replace if necessary.

then

• oil
• oil filter
• air filter
• spark plugs
• fuel filter
  
  if anyone can help with other items and makes models I’ll really appreciate it. In the last year I seem to have purchased 2 928 and a 928s4 but have little idea on servicing / looking after them. Think it’s going to be a steep learning curve.

You will need to replace:

• Fuel lines (in the engine bay - all of them)
• Power steering lines

Unless you like car fires.

You will also need new tires if they were last replaced in the 90's.

Go through the FAQ. From the FAQ...

I might add a water pump to the mix while you're in there.

Oh and also - the sound insulation pad on your hood will probably disintegrate in short order. You can still order OEM. If you have a 2 section pad you will need to order 2 pads and cut one up.

apologies Sir, I had looked at this faq beforehand and forgot. If truth be know I’m not the best on the forums. You’re right, I like to keep all the smoke and flames in the wiring in the car and not let it out.
pill try reading some more stuff and try and avoid posting things that might have been asked before.

No reason to apologize. Sometimes such a reply is just missing context. It's more like a presumption that you might have missed the FAQ altogether if myself or someone else can easily recall an answer there, so it's more like, "Hey, look at this gold mine of info."

Also, learning to use the Search tools will be the greatest asset for enabling your best possible ownership experience IMO.

Good to see someone else from the UK. Leicestershire here.
Check your green wire from the distributor and also have a thorough going through of all of your ground points.

Some things degrade with age and some with use [some both]. Your engine bay wiring for instaance may well be surprisingly OK but check it out- specifically the front of engine harness and whatever you have on those models for engine management [I know little about the earlier engines]. The biggest threat to your motor will likely be the state of the head gaskets. For reasons I cannot fully determine some suffer serious degradation of the head gaskets and when this happens there can be major head corrosion damage [see Michael's current thread on his GTS strip down and tha tis 14 years younger than yours. Some examples can and do sit there quite happily with no major issues but unfortunately there is no way of knowing without strip down at this moment in time.

Not sure what your model has in terms of fuel pressure regulator and dampers but anything with rubber internals exposed to fuel is suspect including fuel lines tank to engine and back again.

Brake fluid should be in serious need of flush, flush, flush - Bleed, bleed, bleed! Among the other things you mentions...
