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 GT3 Mk2 (all Mezger GT/Turbo engines). A failure at speed can spill coolant under and around the car. 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.
Dual-mass flywheel wear
Non-RS GT3s use a dual-mass flywheel; a worn unit shows as free play felt during light acceleration and deceleration.
What fixes it: Replace the flywheel whenever the clutch is replaced.
Rear main seal leak
RMS leaks are a common discussion point; a few cars leaked from the factory early on.
What fixes it: Replace the seal (gearbox-out), ideally with the clutch.
Carbon-ceramic (PCCB) rotor wear/cracking
PCCB discs (optional) 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.
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.
Maintenance schedule

Pick the car, enter its miles and model year: the planner shows what is due now, the next services and the full schedule, whichever comes first, miles or years.

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. Your car's own maintenance booklet is the final word. HBi Auto's recommendations for cars that are tracked, driven hard or stored are being added by our service team.
