Frequently Asked Questions
Why does my 964’s M64 engine leak oil, and does the manual cover the fix?
Oil leaks on the M64 flat-six most commonly originate from the rear main seal, valve cover gaskets, and the chain tensioner area. Yes — the manual includes full step-by-step seal and gasket replacement procedures with torque specifications for every fastener.
Does this manual cover both the Carrera 2 and Carrera 4 platforms?
Yes. Both the RWD Carrera 2 (G50 gearbox) and the AWD Carrera 4 (G64 gearbox with front differential) are fully covered, including platform-specific suspension geometry, differential service, and driveshaft procedures.
Are the Turbo and Turbo S variants included?
Yes. The wide-body Turbo (internally coded 965) running the 3.3L M30/69 and the later 3.6L M64/50 turbocharged engines are covered in full, including boost system, intercooler, and G50/33 gearbox service data.
