What Problems Does the 1998 Porsche 718 Boxster Have?
The 1998 Porsche Boxster (986 generation) is known for several frequently reported problems, with the most infamous being the Intermediate Shaft (IMS) bearing failure. This bearing supports the intermediate shaft in the engine, and its failure can lead to catastrophic engine damage. While not all M96 engines suffer this, it's a significant concern for 1997-2005 Boxsters. For the 1998 model specifically, the single-row IMS bearing is considered more susceptible than later revisions. Potential owners should strongly consider whether the IMS bearing has been replaced or proactively addressed.
Another common issue involves coolant system components, including water pumps, radiators, and expansion tanks, which can fail over time, leading to leaks or overheating. Oil leaks, particularly from the rear main seal (RMS), are also prevalent, though often not as serious as IMS failure if caught early.
Porous cylinder heads are another less common but serious concern for early M96 engines, leading to coolant loss or intermixing. Variocam actuator issues (affecting valve timing) can also crop up. Electrical problems, while generally minor, can include failing mass airflow (MAF) sensors, oxygen sensors, and instrument cluster pixel failures.
The convertible top mechanism, especially the plastic-geared early versions, can fail, requiring repair or replacement. Suspension components like control arm bushings and struts wear out, affecting handling.
Regarding recalls, the 1998 Boxster had a few, primarily for minor issues. One notable recall (98V204000) involved the possibility of the rear suspension trailing arm mounting bolt detaching on certain 1997-1998 models, which could affect vehicle control. Another (97V250000) addressed potential cracking of the fuel filter cover. Always check specific VINs for recall completion. Despite these issues, a well-maintained Boxster can be very reliable, but proactive maintenance and addressing known weaknesses are crucial.

How long will the 1998 Porsche 718 Boxster last?
A well-maintained 1998 Porsche Boxster (986 generation) can easily achieve 150,000 to 200,000 miles or more, often providing 20+ years of enjoyable service. Longevity heavily depends on diligent maintenance, particularly addressing the notorious Intermediate Shaft (IMS) bearing pre-emptively. Owners who perform regular oil changes, coolant system flushes, and replace wear-and-tear items like suspension bushings, ignition coils, and sensors as needed, report excellent long-term durability.
However, neglected examples will show accelerated deterioration. Beyond the IMS, age-related weaknesses include degradation of rubber components (bushings, seals, hoses), electrical gremlins due to wiring harness aging, and potential convertible top motor or transmission issues. Regular inspection and addressing small problems before they escalate are key to maximizing its years of service and durability.
