928 service intervals
 

I hate to ask a newbie stupid question, but I just bought a nicely maintained '84 and I'm trying to find service interval information. I've googled "928 service intervals" and checked through some forums and everyone talks about the timing belt.

But what are the recommended intervals for cap, rotor, plugs, fuel filter, air filter, etc.

Do you just do everything when the t-belt is done? I know everything was done on my car fairly recently. I just want to know when it will need to be done next so I can plan for maintenance.

In your position I would find a good 928 experienced mechanic and have the car checked over from one end to the other, then work out a service plan to suit your budget and preferences with your mechanic. There isn't much value in trusting any work that a previous owner has had done to your car. Everybody forms a unique relationship with a service provider, so my nicely maintained is very rarely your nicely maintained.

None of the usual tune up items are things to have much concern with, they last a LONG time and don't do anything especially bad when they fail.

Fuel lines, timing belt, shocks, brakes, and related suspension stuff are safety items.

My own rule on service is that I restore areas of the car when they get opened up, replacing and renewing everything accessible.

OK. I generally do all my own work (everything from minor maintenance to engine swaps). If there's something I can't figure out in the multi-volume Service Manual there is a good local shop.

I had a major PPI done prior to purchase and have documentation for service on fuel lines, clutch, t-belt, fuel injectors, belts hoses, sensors, transmission replacement / lsd install, ect in a huge 3-ring binder.

I was just trying to see if the stuff I would consider as "tune-up" was any more frequent than the timeing belt service - which it sounds like is not.

Drive and enjoy, always watch for leaks. These cars are rock solid after you get the bugs out as most are from neglected maint from the previous owner. SmileWavy

Sounds like everything works fine, so I would drive it.

Nothing at all showed up in the PPI?

Ground service, generally messing with all the electrical stuff might be a good hobby, or make the outside more shiny and the inside more conditioned. ;)

Well -out of a 4 page PPI check list, one thing did show up. The up shift light doesn't work. I decided I can live with that. The pod was recovered in leather about a year ago, but the leather on the dash is lifting a little near the upper vent.

I'll pull the dash later this year to have that receovered too and when I have the cluster out I'll try to track down what might be causing the upshift light not to work.

Of course the trans is notchy in 1st and 2nd, but from what I 've gathered on the forums that's really just the way it is on the pre-BW trannys.

A quick plug for EuroWorks in Indian Trail NC. They did a very thorough PPI and the technician took plenty of time to talk with me on the phone about the car before I drove up from FL to get it.

Of course I had a compression check done too. Everything was good. One cylinder came back a little high, but still within acceptable limits.

Here's the car BTW -

VERY nice looking car, obviously the previous owner put a lot of time and money into it. Steering wheel looks like Paul Champagne's work, it "almost" makes me like burgundy interiors. ;)

It does need a cover for the 14 pin connector, its a plastic piece that clips to the fender edge and goes under the jump post cap and keeps water off the 14 pin wiring.

Hard to say on the shifting, I've got a 91 Mustang with almost perfect shifting feel, and an 83 928 with 145k miles on the tranny and a new clutch (worst combo, tight clutch old tranny) and it just varies on how the 83 feels. Most mornings when its cold I shift slow and skip second gear going from 1st to 3rd, but yesterday after it was warmed up a bit I was almost power shifting from 1st to 2nd, and thats not normal for my 83. Normally it has a "catch" and delay before going into 2nd.

How well does it downshift into 2nd?

Yeah - it is Paul's work. I'll have him redo the dash/golve box later this year. I hear you on the burgandy interior - but it is a loving tribute to the 80s.

Previous owner was a guy up in NC named Lamar Lutz. He is probably the most meticulous car owner I've ever met. Every page of documtented work in his huge 3-ring binder was in its own plastic sleeve. I know I paid high market for a 16V, but I really wanted a car that had been thoroughly sorted out. I already have my project car (88 300ZX turbo) and I didn't want two. I wanted a well sorted car that I could drive, maintain, and enjoy.

RE: the 14 pin cover, yes - a friend of mine mentioned that. I'll need to track one down.

As for the tranny - its really tight when its cold. Once it warm up it shifts OK. Down shifts to 2nd aren't too bad most of the time. I usually don't have to force it, I just kind of ease it and it seems to slide into 2nd without too much resistance most of the time. However, sometimes it just doesn't want to go. Like you said - it seems hit or miss.

I do blip the throttle on down shift, sort of heel-and-toe, which smooths things out a lot. That tranny seems to really like a rev-matched down-shift, especially into 2nd.

Cool. Thanks a lot for catching that. I'll order one from Pelican today.

Looks very nice and tidy. Never hurts to change oil, rad fluid,bleeds brakes...then continue keeping that binder up to date!!!

BTW...plug wires last awhile. When they start to go you will know it. But they are $$$. The other tune up stuff is cheap.

Drive and enjoy...looks like you found a great car.

Did you drive it home??? Any thoughts?

Nice looking car, congrats with your purchase!

Yeah - I drove about 500 miles home. Made the whole trip in one day. 500 miles there that morning. Looked over the car, dropped off the rental, and drove it back to FL that afternoon. It was my first time driving a 928. I had driven Carrera 3.2s and 944s, 951s, and even a slant nose 87 930 - but a lot of those cars I drove 20+ years ago. The 928 was a great experience for all different reasons than I had anticipated.

If I had been looking for a pure sports car, I may not have made the purchase. But I have a heavily modified '88 (old school) 300ZX turbo that is much faster and handles more tightly in terms of pure performance. I doubt I will actually put the 928 on a track - although maybe once or twice just to see what its like.

And to me the 88Z feels a little more modern than the 928, I guess because that era Z was really an 80s car (came out in 1984) where as the 928 was really a late 70s car that had evolved.

But the 928 is a great GT car and there is so much innovation that is a tribute to Porsches technology of that era - first all aluminum engine with no sleeves, rear mounted trans, alluminum body panels, threaded shock bodies, twin disk clutch, etc. Tons of things that wouldn't show up on other cars for many years. And you can feel the craftsmanship in the car. The car did not skip a beat the whole drive back. I'm definitely enjoying it.

Plus - I'm 40, which means I was in High School in 1983, which means I loved Risky Business. And its probably a bit cliche - but its fun to have a car that can help relive some of those nostalgic memories.

Lastly - it fits baby seats - yes I researched before the purchase, and test fitted it when I got home. We're expecting twins (our first - and only) in about 6 weeks.

No car on earth is better for a one day 500 mile trip than a 928.

500 in a rental car, OUCH. ;)

Very nice car and congrats x 2...or is that 3 ;)

You're going to have your hands full with three babies!
