Hello!
I have a Jazz 03 with almost 260k km on the clock for around a year and a half now. General maintenance is being done roughly every 10-12k km. But I still have one big issue as the title says.
On cold start the car is quiet, the oil is still thick but not even after 10-15 seconds the orchestra begins. I start to hear valves clicking a lot (i assume its the valves, coz i checked videos on Youtube where it was similar). With higher RPMs i cannot hear it, maybe a bit if i concentrate, due to general engine noise.
I had my valves adjusted approximately at 245k km. It helped just a little, but not by much.
One thing I observed recently when going up our small sloped driveway was that when I let the clutch slip a bit whilist going up on idle (not pressing gas) was that the clicking went silent.
I suspect these things:
Timing chain is too loose? (tensioner failing or chain being too stretched out)
If the timing chain is failing, couldnt it skip a teeth too? (some engines are able to function even if the timing isnt 100 percent right)
Could there be some wear on camshaft or rocker arms?
Valve clearance still not good?
The car still runs and drives very well, but I want it to be mechanically in order. The engine, apart from this issue, is pretty healthy and isn't consuming oil (oil level between changes barely decreased, someone tackled that already). And for god's sake I know that Jazz can be quiet, since one elderly couple in my village has the same Jazz and I sound like a tractor going past compared to them
Any clues?
