This a170 petrol 2006 has 165000km and there is this tappet noise.
I had the hydraulic valve lifters replaced, as well as the timing chain, but the noise remains.
What could be the cause ?
Cams worn?
Oil pump pressure?
Faulty oil pump?
Gunk on oil pickup sump?
How to diagnose without taking out the engine?
