What to look for
Coolant pipe fittings (glued/bonded) pulling out
The GT1-derived Mezger engine's coolant manifolds use aluminium pipes bonded into cast housings; after many heat cycles (especially track use) the adhesive can let go and a pipe can pull out, dumping coolant, sometimes onto the rear tyres. Applies to 996 Turbo/GT2/GT3 engines (the cited article's photo is of a 996 twin-turbo engine). Coolant typically escapes quickly as steam; the bigger hazard is coolant on the road or track. From the 911 Buyers shop: this is mainly a concern on cars tracked hard for long sessions; we don't see it fail often on cars driven on the road. Pinned pipes are still a plus when you buy or sell.
What fixes it: Pipes pinned (or re-bonded/welded) in the housings; normally an engine-out job, often combined with clutch/other work.
Carbon-ceramic (PCCB) rotor wear/cracking
PCCB discs (standard on this car) are condemned for chips, cracks or small amounts of wear; replacement is very expensive, and many cars have been converted to steel. Mostly a concern on tracked cars.
What fixes it: Inspect rotors (and pad thickness) before purchase; replace damaged rotors, or convert to iron rotors.
Clutch and flywheel wear
Clutch/flywheel life is shortened by track use; buyers' guides advise budgeting for replacement around 40,000-60,000 miles.
What fixes it: Clutch and flywheel replacement.
IMS bearing (Carrera)
The intermediate-shaft bearing on M96 engines can fail without warning. Many have been upgraded; ask for the invoice. Mezger cars do not have this problem.
Rear main seal
An oil leak between engine and gearbox. Common; often done together with the IMS and clutch.
Bore scoring
Scored cylinder walls on higher-mile engines. A borescope inspection settles it.
Coolant system
Radiators behind the front bumper collect debris and corrode; check them and the expansion tank.

911 (996), 1999–2005: what is done, version by version
Turbo / GT2 / GT3 (Mezger engine):
Not verified yet: Most US intervals for the 996: air and cabin filters, drive belt, gearbox oils; The IMS bearing is not a factory service item; see common repairs.
Confidence: Low. Sources: 1, 2.
Intervals are whichever comes first, miles or years. "Porsche factory (converted from km)" means Porsche's own figure for another market, turned into miles with the same km-to-mile pairing Porsche uses in the US.
