What kind of engine does the Porsche 996 have?
At its debut, the 996 featured the most significant change from the classic 911 series: a water-cooled engine replacing the previously air-cooled engine.
Is the Porsche 996 rare in the world?
The stereo and HVAC systems are nothing but trouble, and the repair costs will reflect the inflation-adjusted $100,000 MSRP, not the $13,000 you paid for the car. The 996 is not rare. It will never be rare.
How to troubleshoot a Porsche 911 Carrera engine?
Here’s a few useful 84-89 carrera tidbits that others sent me while going through my recent diagnosis. 1. Remove a spark plug wire and insert a test plug into the wire, place it next to the engine, have someone crank the engine and look for a spark (or remove one of the plugs and do the same).
Why did the Porsche 911 M96 engine fail?
The M96 engine that powers these cars is subject to complete and total failure due to a weak intermediate shaft (IMS) bearing, a valvetrain component that fails often and requires a total engine teardown to replace, leaving the owner with a 3,100-pound paperweight and a $15,000 bill.
Are there any problems with the Porsche M96 engine?
The M96 (and subsequent similar M97) water-cooled engine is definitely a strong-performing engine, however along the stages of its development it has suffered from some design deficiencies that have been identified and corrected by Porsche over the 11-year lifespan of the engine.
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.
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.
What happens when IMS bearing fails on Porsche?
When the bearing does fail, foreign object debris from the bearing circulates throughout the engine, causing further damage to other areas in the engine. On the early cars, Porsche also used a center bolt to secure the IMS bearing that was too weak and sometimes snapped.
