Inside the Porsche Cayman.
Early 987 Cayman with the M97 engine has the well-known IMS bearing weak point. We inspect at service, photograph, and quote LN Engineering IMS retrofit only when the evidence supports it — not every 987 needs it. The bearing changed midway through production; the retrofit is a permanent solution.
The 981 Cayman moved to the MA1 direct-injection flat-six — a completely different engine architecture, no IMS concern, and one of the most rewarding modern flat-sixes made. The 718 Cayman turbocharged flat-four (MA2) introduced carbon-buildup considerations on the intake valves — walnut blasting around 80–100k km restores factory drivability.
PDK dual-clutch (981 and 718) needs fluid on interval — every 60–80k km, correct spec, factory procedure. Not 'lifetime'. On GT4 cars (981 3.8, 718 4.0 with 6-speed manual), maintenance is closer to a track-day car — brake fluid, pad condition, alignment, coolant all get scrutinised every service.
