I am in the process of buying a 1994 Porsche 968 Cabriolet with approximately 52k miles and wanted to get opinions from experienced 968 owners regarding timing belt service intervals and whether I am being overly conservative.
The car appears to be a fundamentally solid, well-documented example:
A Porsche specialist inspected the car recently and actually did NOT recommend immediate timing belt replacement. Their view was that the belt appeared to be in good condition and they did not see an urgent issue.
However, my understanding has always been that 968 timing belt service is heavily age-based, not just mileage-based, and that catastrophic engine damage is possible if the belt system fails. The current belt service is now roughly five years old.
So my question to experienced 968 owners is:
Would you proactively redo the full front-engine/timing belt service immediately on a car like this despite the low mileage since replacement, or would you consider another 1–2 years reasonable given:
Thanks.
The car appears to be a fundamentally solid, well-documented example:
- clean history
- long-term ownership history
- documented timing belt services throughout its life
- no major leaks
- healthy cooling system
- good PPI overall
- no major structural concerns

- documented replacement history
- low miles since last service
- good inspection findings
- specialist shop not recommending urgent replacement?
- timing belt
- rollers
- tensioner
- balance shaft belt
- cam seal
- balance shaft seals
- oil pump front seals
Thanks.
