Why did Porsche change the oil system on the Carrera?
Oil System Inadequacy: The air-cooled predecessor to the M96 engine incorporated a dry-sump system that was designed to keep a significant amount of oil in reserve for extended performance driving. With the introduction of the M96 engine, Porsche moved away from that design, primarily due to the high cost of implementing a separate dry-sump system.
Is there a problem with my Porsche 911 Carrera?
This “D-chunk” problem seems ironically to occur mostly in gently driven cars. 911 Carreras that are driven hard at the track or on the street do not tend to see this type of damage. At least with respect to the track cars, one theory is that these cars tend to have their oil changed much more often.
Is there a problem with the Carrera 3.4 engine?
The problem affects mostly the 2.5 Boxster and Carrera 3.4 engines. When this failure happens, you will see oil and coolant begin to mix together or a slight unexplained coolant loss. If your engine experiences this failure, it can be rebuilt using LN Engineering’s Nickasil liners installed.
What happens when the air separator fails on a Porsche 911?
When this unit fails, the result is oil sucked out of the engine and into the intake. While the air-oil separator will not cause immediate mechanical damage to your engine, it may make it smoke tremendously and/or run roughly (see Pelican Technical Article: Porsche 911 Air Oil Separator).

What to do if your Porsche Carrera engine is leaking?
If you find that your engine is leaking from the rear main seal (also known as the flywheel seal), then simply install a new one while adding a little bit of Curil-T sealant to help keep it dry (see Photo 10 of Pelican Technical Article: Clutch Replacement on the Porsche 911 Carrera ).
When to change coolant on Porsche 911 Carrera?
To keep your 911 operating correctly, it’s important to check the level, strength, and overall condition of the coolant on a regular basis. You also need to change the coolant before it degrades to the point where it doesn’t perform its job adequately.
