(STRANGE KNOCKING) Hi all,

Could someone guide me, I have Yaris 2002 1.0 VVT-i
I use LPG sistem,
Question: After driving for 30 min or more, until the engine heat`s up, than in idle i hear some knocking noise, soon as i give more gas the knocking is gone, it sounds like some nice diesel car (just a little knocking but not usual for petrol cars) I have chaked the valves at the service, they are OK, i have change the oil , but its all the same. Yaris has 77.000 km, Can it be the Chain Drive??? And on what km/mile has to be changed?

Thank you all
