Done yesterday, easier than expected.
Jazz 1.3 16v 6m Elegance, april 2017.
After 96000 miles, intake valves had increased the gap while exhaust valves were ok.
I've easily changed also the ancillary belt, ten minutes thanks to the automatic tensioner, it was still running but in bad conditions.
4,5 hours including oil and filters change and this is how an engine appears after 96000miles of high quality oil.
