Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I used the method that threeOh advised and it seems to work.
Leading evidence: 'Use method' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'conservative one' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Use method' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suspected cause
The best approach is probably the conservative one: to follow the manual.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just got an '04 C4S with 1K miles on odo. Manual calls for 2K mile break in period, where exceeding 4200 RPM is not recommended, along with the usual varying speeds, no hard braking etc. Does conventional wisdom hold to these parameters? I appreciate advice on best approach for this car. Of note, a 1K mile service was done before I got the car, including a fresh crankcase of Mobil 1 0-40.
Thanks - Phil
I would treat the car very gingerly during the break-in period. The proper approach 'may' save you a whole lot of heartache what with all the RMS failure talk around here. Also, remember not to ramble on the highway at the same speed for excessive periods of time; try to vary it at speed by 10mph regularly.
If you do not test the rev limiter driving off the dealer's lot, you will be doomed to a life of mediocre performance and oil usage.. Always get the engine to full operating temp before driving hard and vary the engine speed periodically.

I used the method that threeOh advised and it seems to work.
1) warm up well.
2) 10 to 20 miles between 3,000 and 5,000
3) 50 miles 3,000 to 7,000. Don't push, slowly bring up the revs, simply keep the engine loaded.
- what do you mean keep the engine loaded and slowly bring up the revs?
4) repeat 2 and 3 3 more times.
5) enjoy
Ah, Phil just wants to give it a ride.
If you haven't hit 6500RPM in that thing yet, you have more discipline than I would. It's a hoot.
Take it for a loooong drive around the East Coast, all under 5000RPM. Hit the Shore, up to Newport and Boston, back over to Albany, and home, and you have your break in period!
I don't know about you guys, but driving the way Porsche recommended for 2k miles would be extremely difficult, I had a hard enough time trying to get to 2k kms, and that was with the method that threeOh suggested. Now I get in the car and drive, sometimes hard, but always trying hit every rev range in every gear. I guess only time will tell.
Thanks for all the advice! Keeping it under 4200 rpm is a killer, but likely worth it in the long run. It does reach operating temp fairly quickly, which is a positive. Damn thing just sounds SOO good!!
