Hi guys: First of all, you're welcome to Soloporsche.com community. We are proud to be the best spanish spoken Porsche forum in the internet, but we are open to worldwide Porsche enthusiastic. In this thread we want to compile as much information as possible referred to M96 engine failures. We'll be very pleased to receive your data about blown engines (car, model year, mileage, failure, and so on). Thanks in advance :[applause]
This is a thread about the very problematic wet-sump 986 Boxster and 996 Carrera engines and not about the problem-free dry sump 996 GT3, Turbo and GT2 old school motors. The engine code starts with M96 for all of them. Big problems: M96.01,02,04 - 996 Carrera 3.4 M96.03 - 996 Carrera 3.6 M96.20 - 986 2.5 M96.21,24 - 986 S 3.2 M96.22,23 - 986 2.7 No problems: M96.70 - 996 Turbo & GT2 M96.76 - 996 GT3 mk1 360 hp M96.79 - 996 GT3 mk2 381 hp My 986 2.5 engine broke 2 times (at 70.000 km something happened to one head and at 110.000 km came the total engine crash, which we are starting to talk in this thread. The wet-sump engines have oil starvation problems and they crash sooner or later. And they crash totally, so you have to buy a new engine. I know personally 5 996 Carreras with crashed engines: 996 3.4 @ 110.000 km 996 3.4 @ 100.000 km 996 3.4 @ 42.000 km 996 3.6 @ 48.000 km 996 3.6 @ 60.000 km +my ex-986 2.5 @ 110.000 km If you search for a 9x6 in www.mobile.de then you see many ads with "ATM" or "Auschtauchmotor" which means the engine is changed. People wonder how can a 911 Carrera be so cheap... Porsche enthusiasts keep away from 996's, so there are not too many people left who would want them. I have had my expensive lessons with the Boxster and I will never return to 986 - the 968 Cabriolet is much better car and the 944 Cabriolet is much-much better product. And they are quicker cars, too. And as I am a person with friends, so the 4-seater is the right car.
