New p-car owner, breaking in rebuilt engine
Hi All, new P-car owner here. I just bought a beautiful well-kept 2005 Carrera S last week. It had 42,000 miles and a recent factory engine replacement only about 100 miles before I bought it. From the service record, it appears that the previous engine had an IMS failure. I felt this was a great buy because not only was I starting with a new engine, but it also came with a 2 yr. warranty on the engine.
I'm also following the break-in procedure for this car by trying to keep the revs below 4200rpm (not as easy as I thought
) for the first 1000 miles (manual says 2000, but I think that's unnecessarily long). Any other recommendations for caring of this new rebuilt engine? Any 997 owners with rebuilt engines out there, how are your cars doing?
Thanks,
Roger

My advise would be to adhere to the 2000 mile break in. Why not? Engine may be brand new. Why not give it time to break in properly. Porsche was free to come up with any number it wanted. One must assume the 2000 mile number is based on something other than a coin toss.
Also, I would treat engine to an early oil/filter service: 500, 750 or 1000 miles; pick a number you like. Then treat engine to another oil/filter service at end of break in.
During the break in period give engine a minute or so of idling after a cold start -- I wait until I hear the secondary air injection pump shut off (Boxster) or when the fast engine idle speed drops down to near nominal (Turbo).
Then I drive the car gently -- both cars are manuals -- keeping engine rpms below 3000 until engine coolant needle has been at nominal operating temperature for a few minutes.
I always with a new or broken in engine, cold warm or hot, avoid real low rpm and high load conditions (lugging).
Once up to temp I just drive the car.
Before shutting the engine off I let it idle a moment or two (the Turbo a bit longer) to shed any heat load that might have built up during harder running, unless the previous couple of minutes of driving was city/stop and go driving in which any heat load built up during say freeway high speed running would have dissipated.
Regardless what you do, enjoy the car!
Sincerely,
Macster.

If you're capable of deeming 1000 miles enough "break-in" why do you solicit other break in guidelines?

Brand new engine or reconditioned? From previous post here indicated most engine replacement are using reconditioned engine. If that's the case, does the break-in guideline apply? Just wondering...

Great advice guys! Thanks! Here's a few snaps I took on my first weekend drive. That first drive on the backroads was surreal! Also just joined PCA - Golden Gate Chapter, looking forward to next years driving events.

Hey there,
I think that's the car I was looking at a few weeks ago. Did you get it from a BMW dealer in the Bay area? Instead of that, I wound up buying one just like it (2005 S, black/tan) closer to home.
Another IMS issue! I was surprised at how many cars had either IMS or RMS issues when I was looking.
Mine has 37k miles on it and I was thinking that if there was a major IMS/RMS issue, it would have happened already but I guess it can strike at any time.
Enjoy!

Were the photos shot on Mt. Tam?
