•Drain and inspect engine oil for any metal particles or debris, presence of metal is a deal-breaker indicating IMS bearing wear
•Confirm IMS bearing has been proactively replaced with LN Engineering retrofit or equivalent, request receipts
•Check all valve cover gasket areas and spark plug tubes with UV light for active oil leaks
•Verify oil pressure behavior with a mechanical gauge, pressure must rise appropriately above 4 bar at higher RPM
•Review full service history for oil change frequency, M96 needs changes every 8,000 km maximum with quality full synthetic
•Have a Porsche specialist perform a pre-purchase inspection including borescope cylinder inspection and oil analysis
•Check production date, not just model year, to determine whether the car has the dual-row (pre-2000) or single-row (2000 onward) IMS bearing

Do not choose a 986 based on displacement or power alone, the IMS bearing risk is tied to production date, not engine size. Cars built from 1996 to 1999 (2.5L) got the more robust dual-row bearing, while every 2.7L and 3.2L S car from 2000 onward got the weaker single-row bearing with a higher documented failure rate. If buying an early 2.5L, the dual-row bearing lowers but does not eliminate risk, so proactive IMS retrofit is still worth budgeting for. If buying a 2.7L or 3.2L S from 2000 onward, treat IMS retrofit as mandatory rather than optional unless documented work already exists.
