This 1999 Porsche 911 (996) experienced catastrophic engine failure from a bad bearing. We removed the old engine and replaced it with a low mileage unit from California. Luckily the new engine came with a brand new factory Porsche air oil separator installed, as well as new OEM spark plugs. The new clutch was installed over a new crank seal, and the air conditioning compressor was swapped out for good measure, as we knew the old one functioned normally. The oil pan was re-sealed and a new LN engineering intermediate shaft bearing retrofit was installed. After reassembly the driveline of this Porsche is in tip top shape.
