Known Issues
Intermediate Shaft Bearing Ims:
While the 964 does not have the same IMS bearing issue as later M96 engines, its predecessor (911 G-Series) had potential oil feed issues that the 964 addressed. However, early engine builds may still require diligent inspection.
Valve Stem Seals:
Can degrade over time, leading to oil consumption and blue smoke on startup.
Head Gasket:
While robust, can fail under extreme heat or if the engine is consistently over-revved.
Varioram System:
Early 964s (1989-1990) featured the Varioram intake system, which can have issues with vacuum leaks or actuator failures affecting performance.
Fuel Pump And Lines:
Aging rubber fuel lines and components can degrade, requiring replacement to prevent fuel leaks.
