I'd like to conduct a survey of 1996-2008 Porsche owners in order to get an idea of what kinds of preventative maintenance have the most value/effect. Whether your car is healthy or if you've experienced an IMSicon failure or bore/cylinder scoring issue, please share. I will post this survey in a number of forums and compile the information in order to get some conclusive data on what works instead of just relying on circumstantial evidence:

1) The year, model, and mileage of your Porsche the last time you drove it (i.e., at the time of failure, if it experienced one)
2) Did your car experience either an IMS or cylinder-scoring-related engine failure?
2a) Did the failure occur on a racetrack?
2b) What was the nature of the failure?
3) What oil is/was used in the car?
4) Did/does the car have a LN engineering spin-on oil filter, or the stock oil filter?
4a) If the filter was a spin-on, did/does the car also have the extra magnetic strip installed?
5) Did/does the car have a magnetic oil drain plug?
6) Did/does the car have a 3rd radiator installed?
7) Did/does the car have a low-temp thermometer installed?
