What is the 1997-2008 Porsche Boxster Intermediate Shaft (IMS) Bearing Failure?
The Boxster shares the M96/M97 engine family with the 911, making it equally susceptible to IMS bearing failure. The sealed bearing loses lubrication and fails, sending metal debris throughout the engine. The 986 Boxster is actually the most commonly affected model due to its pro… Repairs typically run $1,800-$4,000. Severity: high.
What is the 2005-2012 Porsche Boxster Cylinder Bore Scoring?
The M96 and M97 engines in the Boxster develop cylinder bore scoring similar to the 911. Scoring typically occurs on cylinders 1 and 6 due to uneven oil distribution in the flat-six layout. Symptoms begin with increased oil consumption and progress to misfires and rough running. Repairs typically run $6,000-$18,000. Severity: high.
What is the 2005-2008 Porsche Boxster Intermediate Shaft End-Play and Bearing Wear?
Beyond complete IMS bearing failure, the intermediate shaft can develop excessive end-play as the bearing wears. This causes timing chain tension variations and gear mesh changes that produce intermittent rattling and metallic noises. End-play beyond 0.10mm indicates imminent bea… Repairs typically run $2,000-$4,500. Severity: high.

Severity: medium.
What is the 1997-2008 Porsche Boxster Air-Oil Separator (AOS) Diaphragm Failure?
The AOS on the Boxster M96 engine suffers the same diaphragm rupture as the 911 variant. The failed diaphragm allows unmetered air into the intake and oil vapor to bypass the separation system, causing oil consumption, rough idle, and fouled spark plugs. Repairs typically run $400-$1,200. Severity: medium.
