1992 Porsche 968 Problem Reports
Report A Problem
Pinion bearing failure can cause noise in the manual transmission. A revised assembly procedure and components are required for repair.
In automatic transmissions, the flexible hub at the engine flywheel may deteriorate and fail, causing a large amount of play in the driveline. This failure may be caused by prolonged engine oil leaks.
The dual mass flywheel can fail and cause symptoms like noise and chatter when operating the clutch and changing gears.
Aged brake fluid can cause numerous problems and should be replaced regularly.
If engine misfiring, rough running, or fuel consumption issues are not resolved quickly, the catalytic converter can overheat and fail.
Pay close attention to warning lights and have the brakes inspected regularly—immediately address any brake problems. Hard driving habits will cause excessive brake pad and rotor wear.
Suspension components (including control arms, boots, and ball joints) are critical and require regular inspection.
The tensioner for the camshaft chain must be inspected regularly because the non-metallic pad for the timing chain variocam adjuster can crack/break apart unexpectedly. The inspection/repair will require valve cover removal and reinstallation.
The cooling system must be inspected regularly, as small leaks can develop at the reservoir. The heater valve and fan operation should also be inspected.
The front hood and rear deck lid support struts may fail; replacement is required.
