Kelvin, at least before blowing your engine you had some few times of glory cruising at 270! When I blown it, I was stopped at the traffic light... the noise was exactly tha same you described (I thought to an OM Leoncino - a '50-'60 italian small truck) This is my story http://www.renntech.org/forums/index.php?showtopic=4501&hl= (I don't know if the link works but in case you can search here for the title of the 3D "another (?) 996 3.4 engine broken..., is normal that a serviced 67.000 Km...". At last I've spent 11.000 euro for engine, clutch and flywheel replacement. Since, due to the low mileage, I claimed for extra warranty, after 6 months I had back 1K from Porsche as 30% of the only replacement engine list price (5870€ + VAT). The "funny" think (it would be very funny to see how this would be considered in a trial...) is that the "opening the engine for failure search" - must for claiming the warranty - costed me 1K.... :censored: I'm very very very nauseated from Porsche...

Many thanks Loren! But... what should tell this? That if I'm going to repair the engine Porsche will provide me a new modified crankcase and bearing housings (that is the correct word for those things that started to damage the engine, followed by the bearing shells..). The point is: why they have modified the crankcase?... Anything else? (I think customers would had been happier if P had recall this problem instead of 993cabrios...)

today I found this: http://www.alldata.com/TSB/50/99503540.html note TSB Number 11A/0 of august 2003 "Engine - Modified Crankcase/Bearing Housing Usage" that seems exactly my problem... and, finally, regarding the redesigning I found this on PCA web site http://www.pca.org/tech/tech_qa_question.a...3-A86727374661}

Hi, I'm from Italy and I own an immaculate 996 C2 cabrio, built in june '99. The car has a total of 67.000 Km (42000 miles) and it's been always serviced (last service 500 km ago). Saturday, after a little 50 km highway ride, when I stopped at a red light near home I heard a big mechanical noise coming from the engine... but the engine was running great since i stopped.. no warning lights on the dash and strong oil pressure. I was 500mt from home so I ride very very slow to park the car in the box... On monday I put the car on a truck and I went to my service.... He found some small copper pieces in the oil! He first thought to valvle guides, but when he removed the crankcase oil screen he found... parts of bearing shells! I've heard that this is a very well known problem of 3.4l engines and Porsche redesigned the entire crankcase... and the solution is: ENGINE REPLACEMENT. The problem is that the car is out of warranty and the cost here in Italy will be about 8-9Euro (10-12K US$) for a replacement engine. My question is: do Porsche recognize that this is a design mistake? If my engine had 100.000 miles I'd be prepared for the replacement but not on a 40k miles engine! I bought a Porsche, a brand whose reputation is also made with reliability... next time will I have to buy a Jap? Someone has some previous references? Thanks
