What to look for
IMS bearing (997.1)
Still present on the M97, but the larger bearing fails far less often than on the 996. It cannot be replaced without opening the engine.
Bore scoring (997.1)
More common on the 3.8 S. A borescope is the only way to know before you buy.
Coolant pipes and radiators
Same front radiators as the 996; check for debris and leaks.
PDK (997.2)
Reliable; check the software and that the fluid was done on schedule.

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.

Written by the 911 Buyers and HBi Auto team in Mocksville, NC. Market numbers come from 911 Tracker's VIN-checked US sales and say what they are based on; maintenance intervals say where each one comes from. This course is general information, not an inspection, an appraisal or legal or tax advice.
