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?

Nobody's willing to help out?

The problem with these kinds of surveys is that you get a terribly skewed sample of respondents. The majority of respondent will be the ones who have had issues with a smattering on ones who haven't had problems. I don't believe the results tell you anything.

Skewed or not, here goes.

1) I have owned a 2001 Boxster S since 2010. I'd intended to keep it six months, but its charms overwhelmed me.

2) Never had any IMS troubles, thank goodness, and in my very unscientific opinion, they're grossly overfeared.

3) I use very ordinary oil, 10-30W, and change every 5K miles, with filter changes at 10K. I have a lift, so I change it myself.

4) Stock filter.

5) No magnetic plug.

6) Normal OEM cooling system. Changed waterpump and thermostat soon after I bought the car.

7) OEM thermostat.

I'll be interested to see what sorts of responses you get.
