Guess the same problem with my cultus 2006, oil being used is zic high flow (20w-50). Mechanic said not to use zic a , as engine not in so good condition so it will reduce the oil.
As soon as u start the engine u can hear the noise like "tik tik" and sound remains there on idle. So for that a month or three weeks ago I get my head worked from khiradiya , tikki , valve, waterbody etc all were installed new, even the cam(kabuli) was changed. But the sound is still there, Sound like tractor engine or sewing machine u can say. what to do @Xulfiqar bhai and other seniors . Need help
