Upside I reckon is that it pushed me into a 911, but I'm still wounded over it.

Well guys, I don't know. My car is one of the oil users. I 've used a fair bit of oil, probably 4-5 litres in just over 8000 kms. Most of my running is around town with some trips and the odd track day thrown in but my impression is that it mainly uses oil around town. I always check it before and after a trip or a track day and I don't recall having to top it up after....go figure!
Steve - the build date on mine is September 2008. No fuel pump issues. Just starts and runs like a good Porsche should.

My 09 C4S had issue at 2200 miles related to the PCM (it reboots itself continuously, brought it into the dealership and they replaced it with a brand new one), car has ~ 11K miles now and NO ISSUE at all. My 09 C2S cab has ~2400 miles and NO ISSUE what so ever.

Simsgw, I also fly and am well aware of testing (draining/viewing) the fuel before each flight. It is very easy to see it in the fuel but unless you analize the oil, like Macstr writes, you really don't know the amount of water/fuel in it.
Most aircraft owners have their oil analyzed at each oil change to verify what is in the oil. If excess water or oil is in it then you start doing things different on engine operation and maintenance.
I have the oil analyzed, at each change, on each vehicle I own, to track what is happening. I also always get the OIL up to operating temps to help get rid of any condensation/fuel that may develop during engine warm up. There are times on very short trips I will go many miles out of my way to make sure the OIL us up to temp. I also change my oil at 5,000 miles and/or twice a year, before storage, if the mileage is shorter.

Oil is very hygroscopic though. If opportunity is given for water to accumulate it certainly will. I just never thought about using a Porsche that way myself.

I was notified today that the part was not available and will be sent from germany so I may not get my car back until next week. Given the number of cars to have experienced this issue in the US, I would have expected that this part was available. Nonetheles, there isnt anthing that i can do about it right now.
We will see what happens soon.

I finally got my car back today and it is running fine at this time. I only drove it home so I will see when I get a chance to put in on the road again.
My car was built as it was built 01/09. Maybe that is why I had a bad fuel pump. It seems like the earlier builds have the bad HPFP.

Having problems with my Cayman S now..I suspect its the high pressure fuel pump 
It takes a few cranks to start the engine now..And when driving down to the garage to get it checked, it was offbeat for a while..The car started to jerk and there was no power! Fuel starvation maybe?? But the fuel level is 3/4 though..When finally reached my local garage, the PIWIS tester showed 3 faults on the DME.
1.)P0441 - Tank Vent System
2.)P1024 - Fuel High Pressure Too High After Engine Off
3.)P1023 - Fuel Pressure / Fuel Volume Too Low At Start
The technicians are currently checking on it, and will inform me once they are done with their diagnosis.
Got a really bad feeling its the HPFP though..
