Thank you, I also thought they were. I asked my mechanic today and on checking Autodata it didn't really give much info. My brother is handily serving his apprenticeship with Renault, and has been suggested to him that it's worth putting the new belt on, timing it up properly and seeing how it goes as it was near enough idling speed. New INA belt kit ordered and water pump as well. Hoping this 440 can live another day.
