Timing belt; age or mileage? My Porsche 944 had it's timing belt replaced
8 or 10 years ago, but I probably haven't driven it 4,000 miles since then. Opinions on whether it should be replaced again or ride with it? This vehicle is strictly for amusement.

I'm seeing 60 to 100k for replacement type stuff, nothing on age.

...dry rot or other deterioration of the belt. I would think it's OK, but one never knows...

If it's an interference engine, I'd probably have someone you trust check the condition of the belt. If it's a non-interference engine (doubtful, but I know nothing about Porsches), I'd drive it without worry until you hit the mileage at which replacement is recommended.

the pistons and valves don't clear each other, so if the belt were to snap well yeah, they'd maybe totally destroy the engine. ButI know nothing about Porsches.
