Problems and faults: Porsche 964 911 Cabriolet
- Early Porsche 964 911 engines were built without a cylinder head gasket and a small percentage leaked. In 1991, Porsche updated the production engines by adding a cylinder head gasket, redesigning the cylinder head base, and installing all steel head studs.
- From 1990, the Porsche 911 was fitted with a dual mass flywheel – to isolate drive-train vibration – though the early Freudenberg units were unreliable. In 1992, Porsche changed to more reliable LUK-manufactured units.
- In late 1993, Porsche added a vent kit for the distributor, to help prevent the dual distributor rubber belt from breaking due to ozone concentrations – these kits can be retrofitted.
- For vehicles produced before 1991, oil leaks from the transmission are not uncommon.
- Corrosion may occur around the windscreen, side windows and the engine bay.
