Why does my 996 Boxster blow smoke out of the exhaust?
996, 997’s, and Boxsters use an oil air separator which basically reduces oil vapor that recirculates in the engine. Unfortunately, they use a rubber diaphragm that is prone to failure. The result is excessive smoke out of the exhaust on start up and driving.
Why does my Porsche Cayman have white smoke?
White/Bluish smoke on cold start, and it makes a giant, embarrassing and smelly smoke screen in the driveway or on the street… That was exactly what happened to my 2008 Porsche Cayman. Although this problem seems more common among 986 Boxster and 996 911, some other Porsche sports cars may have the same issue.
Why do I get smoke when I start up my Porsche?
It lasts for a second or two only. There is no smoke during driving. After driving, a subsequent start-up will not produce any smoke until the car has been parked for an hour or so. After resting, the smoke appears again. Oil level is around half-way, so not an overfill. The oil separator was replaced around 2000 miles ago.
Why is white smoke coming out of my exhaust?
Most people’s initial reaction when they see white smoke coming out of their exhaust, is to assume the worse…..blown headgasket, slipped cylinder lining, catastrophic engine failure. While on rare occasion that is the case, many times it is nothing more than a bad Oil Air Separator (OAS, AOS, Air Oil Separator, etc).

Why does my Porsche Boxster have smoke coming from the engine?
A quick puff of smoke as you start a cold engine is not uncommon, especially on the Porsche flat six engine in the Boxster. There are many theories and various thoughts as to why this happens – none are proven.
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 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 there smoke coming out of my exhaust?
The result is excessive smoke out of the exhaust on start up and driving. Some smoke on start up is normal on a horizontal engine, but it shouldn’t last more than 10-15 seconds. When the OAS fails, the car will start smoking for longer periods of time, until is a huge smoke cloud as you drive.
Why does my car smoke when I start up?

When the OAS fails, the car will start smoking for longer periods of time, until is a huge smoke cloud as you drive. One of the other symptoms of a failed OAS, is a chirping or harmonic noise near the rear of the engine by the transaxle.

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.
What kind of engine does a Boxster 2.5 have?
The problem affects mostly the 2.5 and Carrera 3.4 engines: the 3.2 Boxster S engine appears to be unaffected because it has thicker cylinder walls than the 3.4 engine. When this failure happens, you will see oil and coolant begin to mix together, or a slight unexplained coolant loss.
