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.
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.
Are there any issues with the Porsche Boxster M96?
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. At one end, the shaft drives the oil pump and at the other, finishes in a sealed bearing.

Why is there a problem with my Porsche 911?
Crankcase vacuum exceeds the normal range in the engine under heavy acceleration and sucks in air damaging the rear main seal. This is commonly seen on Audi engines as well. A failing aos also causes too much oil to pass into the intake and will force the engine management to adjust fuel mixtures to compensate.
What’s the difference between a Porsche Boxster and a Boxster S?
Unlike its Boxster brother, the S version of the mid-engined Porsche roadster offered a 3.4-liter unit from its predecessor, but with some improvements and a lower vehicle mass. The Boxster S showed the world that the mid-engine cars might not be as expensive as a Diablo or a Ferrari.

What causes a Porsche Boxster engine to leak?
On the early cars, Porsche also used a center bolt to secure the IMS bearing that was too weak and sometimes snapped. If this bolt breaks, then the intermediate shaft begins to float around in the bottom of the engine, and you can soon experience catastrophic engine failure. This area is also highly prone to leaks.

Where are the oxygen sensors on a Porsche Boxster?
Keeping the engine at the stoichiometric level (14.6:1 air/fuel ratio) helps the engine generate the most power with the least amount of emissions. The oxygen sensors are located in the exhaust system of the engine, and they sense the oxygen content of the exhaust gases.
Why did my Porsche 911 fail the smog test?
My Porsche 911 just failed the smog test because the emission monitors were incomplete… specifically the oxygen sensor monitor. I’ve driven it for at least 100 miles but I still can’t get the monitors complete. Do you happen to know the exact drive cycle to follow to get the monitors ready?
What should I do with my Porsche 911?
A. Start your Porsche 911 and let it idle for approximately 2 1/2 minutes. This will allow the ECU to diagnose oxygen sensor aging; meaning the computer will be monitoring the oxygen sensor warm-up period and reaction to rising exhaust temperatures. During this period the ECU is also testing the Secondary Air Injection system. B. Begin driving.
What happens if the oxygen sensor is not working?
In general, if the oxygen sensor is not working, the car will be running very poorly, and will also be outputting a lot of harmful emissions. Almost all of the time, the Boxster’s computer will give a warning signal that lights up the Check Engine Lamp if the signal received by the computer is out of its normal range.
