Top Risk Areas
The systems that tend to fail first on the 2002 Porsche Boxster, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The bearing for the intermediate shaft, which drives the camshafts, is prone to premature failure, leading to metal debris in the oil and eventually catastrophic engine failure if not addressed. This is a design flaw in the M96 engine.
Cylinder walls can develop scoring, particularly on the non-driven bank, due to issues with piston coatings, clearances, and possibly fuel wash. This leads to increased oil consumption, rough running, and eventually engine rebuild or rep…
The Air/Oil Separator can fail, allowing excessive oil to be drawn into the intake manifold. Symptoms include significant white smoke from the exhaust, rough idle, and increased oil consumption. While not catastrophic, it's a messy and c…
