So what is the highest mileage Air-Cooled Porsche out there?

[ooid]

I know I would definitely be eaten alive by 993 and 964 mafia but why not? We have seen the famous 300k 996, and a few 986 boxsters out there so far. Would be good to see some super-high mileage air cooled Porsches, and owner advice on maintenance and etc? (ideally with the original engine condition).

That was beautiful. I think it was stolen a few months ago, poor guy was posting everywhere but they found it later on. -He managed to have 3 engine rebuilds though in that 1million ; )

I think the highest 993 one at 911uk forum is around 234k yet

Impressive

Yup, I remember seeing that.. Some interesting insight from him also; (loved his emissions trick, lol)

[i]The key to longevity:
1. ONE DRIVER!
2. Service - The car has been serviced by Porsche throughout, and only by 2 mechanics. I started out doing oil changes every 5,000 miles. I thought this would be a good selling point and hadn't kept a car more than 2 years. Once I hit 100,000 miles and realized that I would be keeping the car, I began doing oil changes every 15,000 miles. My miles however are mostly on the highway.
3. The break in: I had the advantage of starting off with a car with 42 miles on the odometer. I did the break in by the book. I kept the revs below 4000, no heavy throttle inputs etc. It was painful.
4. The warm up: I ALWAYS do a proper warm up. Revs below 4000, no heavy throttle inputs. In a mile or two the temperature gauge starts to move a bit and it's time to go.
5. Driving: I don't baby the car at all, but I don't beat it up either. I avoid heavy throttle inputs when the rpm's are below ~3000. The engine likes to rev and I stomp on it all the time when I'm up in the power band.
6. Oil consumption: I don't remember ever adding oil when I was changing it every 5000 miles. This engine was built right. Once I went to every 15,000 miles I would add a quart or 2 in between oil changes. In the past few months I've been adding oil more frequently, but the engine was leaking some, so consumption is hard to gauge. At the 300,000 mile service the leak was addressed . They replaced some gaskets (for the second or third time).
7. Repair: For the most part, the only things that have needed replacement are parts that are expected to wear out. Brakes, suspension parts, spark plugs, distributor caps, belts etc. I don't know where all of the records are anymore, but I only remember replacing the alternator, the SAI check valve, the clutch once, the top twice, the head unit (7 or 8 times), a bent tie rod once.
8. The SAI CEL: I first got the SAI CEL around 90,000 miles. It didn't matter then because I lived in rural southern VA and didn't need to pass any emissions test. I addressed it with a piece of black tape. When I moved back to the Phila area, and needed to pass emissions, they did a SAI flush. This unclogged 5/6 ports. I still throw the SAI CEL every 1-2,000 miles but I can reset it and get all the flags to come up O'K and fake my way through emissions testing (10 years [/i]
