Are there any problems with the 986 Boxster?
The upgraded aos features a doubling in size of capacity for scavenging and is less prone to sucking up oil during high speed cornering. M96 engines fitted to the 986 and 987 Boxster can have issues with a bearing at one end of the engine intermediate shaft. The shaft connects the two ends of the engine timing gear.
Why does my Porsche Boxster have an AOS problem?
The AOS has caused numerous issues on Porsche engines and is an item to be closely monitored. As the membrane in the AOS fails, oil is sucked into the air intake. Initially this can show up as a check engine light for fuel adaptations with oil being deposited on the o2 sensors causing emission faults.

Why is the spark plug leaking on my Boxster?
Spark plug tube seals are also prone to leaking – leaks from the spark plug tube seals can be frustrating. Often, you wont see the oil initially, as it’s sealed in by the coil on top of the spark plug. The tube fills with oil and causes misfires by destroying the plug and the coil.
