1999 996 Engine Reliability & RMS


Vehicle Information: Year: 1999; Body Type: Cabriolet; Total Mileage: 19,486;

The more I read about the 1999 996, the more concerned I become about the overall "longevity" of the car. I am a fanatic about preventative maintenance, changing ALL fluids about double as specified, cleaning the radiators,oil & filter every 2,000 (Mobil 1 since new) or 1 year. Replaced the belt, just to be safe - you get the idea. Always Dealer serviced with Porsche fluids, etc. Dealer even remarked last visit that car has never even hit the rev limiter (Big Brother in the ECU). This car is treated better than I treat myself - and yet, now that the warranty has expired, I am having more difficulty enjoying the car due to all the press about engine replacements and crate motors and the dreaded RMS failure. The impression I'm getting is that regardless of how well the car is maintained or carefully driven, it's a matter of chance whether the RMS goes or some other unknown (or unadmitted by Porsche "weakness")means new engine at owners expense. I certainly don't want to sell the car but the possibility of a $20,000 engine replacement is a concern. Some say that at 19,000 miles, if it was going to fail, it would have. Others say, early 996 engines go with no warning anywhere from 2,000 to 90,000. I'd be happy with the latter but life is full of uncertainty. Absent trading for a 2003 or 2004, any suggestions on how to improve the odds for engine life?As always, your knownledge of these cars is amazing and your assistance is of great value to me.
