timing belt or timing chain?

[alwayz_yummy]

mali ka, wala pa ko nakikitang local revo na timing chain--7k is still timing belt, 1kz, 1zz, 1kd, etc.. all passenger models ng toyota uses timing belt. nissan offers timing chain talaga, from ga16, qd32, td27, sr20, etc....

and i dont believe na makina ng avanza ay timing chain.. its practicallty the same as what the vios/echo has.....and most top-end models nga ng toyota timing belt parin...even diesl engines...
