5k was too little actually it was like laddu charawnga exam me pass kar do. I got so relieved to hear that other 75hps running without timing kit change. There was few 75hps who had failures. But I still think for short distances and city run cars 7.5k km oil change interval is good. Btw Pradeep what kind of noises did you hear when timing chain gave up? Were there any other symptoms apart from chain noise?
